Referring also to FIG. 3, audio recording system 104 may include directional microphone array 200 having a plurality of discrete microphone assemblies. For example, audio recording system 104 may include a plurality of discrete audio acquisition devices (e.g., audio acquisition devices 202, 204, 206, 208, 210, 212, 214, 216, 218) that may form microphone array 200. As will be discussed below in greater detail, modular ACD system 54 may be configured to form one or more audio recording beams (e.g., audio recording beams 220, 222, 224) via the discrete audio acquisition devices (e.g., audio acquisition devices 202, 204, 206, 208, 210, 212, 214, 216, 218) included within audio recording system 104.
For example, modular ACD system 54 may be further configured to steer the one or more audio recording beams (e.g., audio recording beams 220, 222, 224) toward one or more encounter participants (e.g., encounter participants 226, 228, 230) of the above-described patient encounter. Examples of the encounter participants (e.g., encounter participants 226, 228, 230) may include but are not limited to: medical professionals (e.g., doctors, nurses, physician's assistants, lab technicians, physical therapists, scribes (e.g., a transcriptionist) and/or staff members involved in the patient encounter), patients (e.g., people that are visiting the above-described clinical environments for the patient encounter), and third parties (e.g., friends of the patient, relatives of the patient and/or acquaintances of the patient that are involved in the patient encounter).
Accordingly, modular ACD system 54 and/or audio recording system 104 may be configured to utilize one or more of the discrete audio acquisition devices (e.g., audio acquisition devices 202, 204, 206, 208, 210, 212, 214, 216, 218) to form an audio recording beam. For example, modular ACD system 54 and/or audio recording system 104 may be configured to utilize audio acquisition device 210 to form audio recording beam 220, thus enabling the capturing of audio (e.g., speech) produced by encounter participant 226 (as audio acquisition device 210 is pointed to (i.e., directed toward) encounter participant 226). Additionally, modular ACD system 54 and/or audio recording system 104 may be configured to utilize audio acquisition devices 204, 206 to form audio recording beam 222, thus enabling the capturing of audio (e.g., speech) produced by encounter participant 228 (as audio acquisition devices 204, 206 are pointed to (i.e., directed toward) encounter participant 228). Additionally, modular ACD system 54 and/or audio recording system 104 may be configured to utilize audio acquisition devices 212, 214 to form audio recording beam 224, thus enabling the capturing of audio (e.g., speech) produced by encounter participant 230 (as audio acquisition devices 212, 214 are pointed to (i.e., directed toward) encounter participant 230). Further, modular ACD system 54 and/or audio recording system 104 may be configured to utilize null-steering precoding to cancel interference between speakers and/or noise.
As is known in the art, null-steering precoding is a method of spatial signal processing by which a multiple antenna transmitter may null multiuser interference signals in wireless communications, wherein null-steering precoding may mitigate the impact off background noise and unknown user interference.
In particular, null-steering precoding may be a method of beamforming for narrowband signals that may compensate for delays of receiving signals from a specific source at different elements of an antenna array. In general and to improve performance of the antenna array, in incoming signals may be summed and averaged, wherein certain signals may be weighted and compensation may be made for signal delays.
Machine vision system 100 and audio recording system 104 may be stand-alone devices (as shown in FIG. 2). Additionally/alternatively, machine vision system 100 and audio recording system 104 may be combined into one package to form mixed-media ACD device 232. For example, mixed-media ACD device 232 may be configured to be mounted to a structure (e.g., a wall, a ceiling, a beam, a column) within the above-described clinical environments (e.g., a doctor's office, a medical facility, a medical practice, a medical lab, an urgent care facility, a medical clinic, an emergency room, an operating room, a hospital, a long term care facility, a rehabilitation facility, a nursing home, and a hospice facility), thus allowing for easy installation of the same. Further, modular ACD system 54 may be configured to include a plurality of mixed-media ACD devices (e.g., mixed-media ACD device 232) when the above-described clinical environment is larger or a higher level of resolution is desired.
Modular ACD system 54 may be further configured to steer the one or more audio recording beams (e.g., audio recording beams 220, 222, 224) toward one or more encounter participants (e.g., encounter participants 226, 228, 230) of the patient encounter based, at least in part, upon machine vision encounter information 102. As discussed above, mixed-media ACD device 232 (and machine vision system 100/audio recording system 104 included therein) may be configured to monitor one or more encounter participants (e.g., encounter participants 226, 228, 230) of a patient encounter.
Specifically, machine vision system 100 (either as a stand-alone system or as a component of mixed-media ACD device 232) may be configured to detect humanoid shapes within the above-described clinical environments (e.g., a doctor's office, a medical facility, a medical practice, a medical lab, an urgent care facility, a medical clinic, an emergency room, an operating room, a hospital, a long term care facility, a rehabilitation facility, a nursing home, and a hospice facility). And when these humanoid shapes are detected by machine vision system 100, modular ACD system 54 and/or audio recording system 104 may be configured to utilize one or more of the discrete audio acquisition devices (e.g., audio acquisition devices 202, 204, 206, 208, 210, 212, 214, 216, 218) to form an audio recording beam (e.g., audio recording beams 220, 222, 224) that is directed toward each of the detected humanoid shapes (e.g., encounter participants 226, 228, 230).
As discussed above, ACD computer system 12 may be configured to receive machine vision encounter information 102 and audio encounter information 106 from machine vision system 100 and audio recording system 104 (respectively); and may be configured to provide visual information 110 and audio information 114 to display rendering system 108 and audio rendering system 112 (respectively). Depending upon the manner in which modular ACD system 54 (and/or mixed-media ACD device 232) is configured, ACD computer system 12 may be included within mixed-media ACD device 232 or external to mixed-media ACD device 232.
As discussed above, ACD computer system 12 may execute all or a portion of automated clinical documentation process 10, wherein the instruction sets and subroutines of automated clinical documentation process 10 (which may be stored on one or more of e.g., storage devices 16, 20, 22, 24, 26) may be executed by ACD computer system 12 and/or one or more of ACD client electronic devices 28, 30, 32, 34.
As discussed above, automated clinical documentation (ACD) process 10 may be configured to automate the collection and processing of clinical encounter information to generate/store/distribute medical records. Accordingly and referring also to FIGS. 4-8, ACD process 10 may be configured to obtain 300 encounter information (e.g., machine vision encounter information 102 and/or audio encounter information 106) of a patient encounter (e.g., a visit to a doctor's office) of at least a first encounter participant, wherein the encounter information may include audio encounter information obtained from at least a first encounter participant (e.g., encounter participant 228, 226, 230, and/or 242). ACD process 10 may further be configured to process 302 the encounter information (e.g., machine vision encounter information 102 and/or audio encounter information 106) obtained from at least the first encounter participant, e.g., to generate an encounter transcript (e.g., encounter transcript 234) and/or generate 304 a user interface displaying a plurality of layers associated with the audio encounter information obtained from at least the first encounter participant. In some implementations, ACD process 10 may process at least a portion of the encounter transcript (e.g., encounter transcript 234) to populate at least a portion of a medical record (e.g., medical record 236) associated with the patient encounter (e.g., the visit to the doctor's office). Encounter transcript 234 and/or medical record 236 may be reviewed by a medical professional involved with the patient encounter (e.g., a visit to a doctor's office) to determine the accuracy of the same and/or make corrections to the same.
As noted above, ACD process 10 may process 302 the audio encounter information obtained from at least the first encounter participant. In some implementations, processing 302 the first audio encounter information may include defining 306 linkages between each of the plurality of layers associated with the audio encounter information. For example, the first layer of the plurality of layers may be an audio signal associated with the audio encounter information (e.g., complete audio of the encounter, encompassing and clearly delineating each participant), wherein the second layer of the plurality of layers may be a transcript associated with the audio encounter information (e.g., a diarized audio transcript (verbatim) for each participant in the encounter), and wherein the third layer of the plurality of layers may be a medical report associated with the audio encounter information (e.g., a draft medical report in the appropriate clinical output format). In some implementations, additional layers may include, e.g., the above-noted machine vision-based recording of the encounter, including various signal formats and features, and discrete, standardized, actionable data resulting from the encounter, including, but not limited to medication plans (for example, in RxNorm) or lab orders (for example, LOINC) or diagnoses (for example, ICD10, CPT etc). In the example, the signals captured from the encounter information may be processed 304 into at least the above-noted three separate, yet closely linked and interdependent layers.
In some implementations, ACD process 10 may include an ASR portion that may process 302 the audio encounter information producing an approximate (e.g., diarized) verbatim transcript along with alignment information indicating the audio interval corresponding to each transcript word. In some implementations, a deep learning (e.g., sequence to sequence) model associated with ACD process 10 may convert the transcript to a medical report. It will be appreciated that various attribution techniques may be employed by ACD process 10 that may effectively softly assign responsibility for a given output (e.g., medical report) word to input (e.g., conversation transcript) words (e.g. attention weights, integrated gradient, etc.) according to the model. As a result, this may provide a soft mapping from the transcript word positions to report word positions. In some implementations, the input word position assigned maximal attribution for a given output word may be interpreted as being aligned (linked) to that output (e.g., when a hard mapping is required). Based on the ASR time alignment, a word in the draft medical report, aligned to a word in the ASR conversation transcript, may now be associated with an audio time interval of the associated audio signal of the audio encounter information.
In some implementations, ACD process 10 may also may link (i.e., align) the ASR conversation transcript words with the draft medical report words. For transcript words that may have maximal attribution value for some set of medical report words, ACD process 10 may link them with the first word in that set. For the remaining transcript words, ACD process 10 may link them to the same word that the nearest preceding (or if none, nearest subsequent) conversation transcript word is linked to.
In some implementations, a visual recording (e.g., video stream of the patient encounter), if available, may also be a layer and may be time indexed and thus a given point in the recording may be associated with the same time in the audio recording and thus a conversation transcript word and draft report word. In some implementations, if discrete, standardized, actionable data is produced as a second (parallel) output sequence of the sequence to sequence model, then a similar model output attribution technique may be used to align tokens in this actionable data with the ASR conversation transcript words, and thus the audio intervals.
In some implementations, ACD process 10 may generate 304 a user interface displaying a plurality of layers associated with the audio encounter information obtained from at least the first encounter participant. For example, and referring at least to the example implementation of FIG. 5, an example user interface (e.g., user interface 500) is shown. It will be appreciated that UI 500 is shown merely for example purposes only, and that more or less features and arrangements of features may be used without departing from the scope of the present disclosure.
As can be seen from FIG. 5, UI 500 includes the first layer of the plurality of layers (e.g., first layer 502 which may be a visualization and/or direct play-back of an audio signal associated with the audio encounter information (e.g., complete audio of the encounter, encompassing and clearly delineating each participant), second layer 504 of the plurality of layers which may be a transcript (e.g., encounter transcript 234) associated with the audio encounter information (e.g., a diarized audio transcript (verbatim) for each participant in the encounter), and third layer 506 of the plurality of layers which may be a medical report (e.g., medical report/record 236) associated with the audio encounter information (e.g., a draft medical report in the appropriate clinical output format). It will be appreciated that that each layer (audio, transcript, draft report, etc.) may be rendered in multiple different ways, and in the most appropriate way for a given use/preference of the end-user. As such, the specific rendering of layers should be taken as example only and not to limit the scope of the disclosure.
As noted above, encounter transcript 234 (via second layer 504) and/or medical record/record 236 (via third layer 506) may be reviewed by a medical professional involved with the patient encounter (e.g., a visit to a doctor's office) to determine the accuracy of the same and/or make corrections to the same. For example, a scribe involved with (or assigned to) the patient encounter (e.g., a visit to a doctor's office) may review encounter transcript 234 and/or medical record 236 to confirm that the same was accurate and/or make corrections to the same. In the event that corrections are made to encounter transcript 234 and/or medical record 236, automated clinical documentation process 10 may utilize these corrections for training/tuning purposes (e.g., to adjust the various profiles associated the participants of the patient encounter) to enhance the future accuracy/efficiency/performance of automated clinical documentation process 10.
Alternatively/additionally, a doctor involved with the patient encounter (e.g., a visit to a doctor's office) may review encounter transcript 234 and/or medical record 236 to confirm that the same was accurate and/or make corrections to the same. In the event that corrections are made to encounter transcript 234 and/or medical record 236, automated clinical documentation process 10 may utilize these corrections for training/tuning purposes (e.g., to adjust the various profiles associated the participants of the patient encounter) to enhance the future accuracy/efficiency/performance of automated clinical documentation process 10.
As such, and referring at least to the example implementation of FIG. 6, assume for example purposes only that a scribe is reviewing the encounter information using UI 500. In some implementations, ACD process 10 may receive 308 a selection of a first portion of the audio encounter information at a first layer of the plurality of layers on the user interface, and ACD process 10 may display 310 an annotation of at least one of a second layer of the plurality of layers and a third layer of the plurality of layers corresponding to the first portion of the audio encounter information of the first layer of the plurality of layers selected on the user interface. For instance, the scribe may use, e.g., cursor 508 or other known input techniques, to select a portion of first layer 502 (i.e., the audio information of the audio encounter information), which may be received 308 by ACD process 10. As a result, in some implementations, ACD process 10 may display 310 some kind of annotation of either the second layer (e.g., the portion of the transcript associated with the selected portion of the first layer) and/or the third layer (e.g., the portion of the medical report associated with the selected portion of the first layer). In the example, ACD process 10 has displayed an annotation (e.g., bold font) of the second layer (e.g., the portion of the transcript associated with the selected portion of the first layer) and the third layer (e.g., the portion of the medical report associated with the selected portion of the first layer). It will be appreciated that any type of annotation may be used (e.g., bold, italics, underline, highlights, shading, transparency, etc.) without departing from the scope of the present disclosure. As such, the use of bolding as the annotation should be taken as example only and not to otherwise limit the scope of the disclosure.
Similarly, in some implantations, ACD process 10 may receive 312 a selection of the first portion of the audio encounter information at one of the second layer of the plurality of layers and the third layer of the plurality of layers on the user interface, and ACD process 10 may provide 314 audio of the first layer corresponding to the first portion of the audio encounter information of one of the second layer of the plurality of layers and the third layer of the plurality of layers selected on the user interface. For example, and referring to the example implementation of FIG. 7, the scribe may use, e.g., cursor 508 or other known input techniques, to select a portion of second layer 504 (e.g., the transcript), and/or the third layer (e.g., the medical report) which may be received 312 by ACD process 10. As a result, in some implementations, ACD process 10 may provide 314 the audio of first layer 502 (e.g., the audio information of the audio encounter associated with the selected portion of second layer 504).
As such, ACD process 10 may leverage the above-noted defined linkages, such that the encounter recording as captured above may be provided to a human scribe (or physician) in such a fashion, so that they may navigate through each of these layers independently and be always in sync. For instance, if the scribe navigates through first layer 502 (audio) by listening, the part of the transcript that corresponds to that part of the audio may be bolded, highlighted, etc. accordingly, as well as the resulting medical report (and if relevant actionable data) from that information. Additionally/alternatively, if the scribe selects a part of the report, the audio/transcript sections that affected that part of the report may be bolded, highlighted, emphasized, etc. This annotation also may correspond to the audio and report “cursor” (e.g., audio cursor 510) moving, e.g., audio may next play from that position and typing/keyboard-navigation may commence from that position in the report. As a result, since each of the plurality of layers may be synchronized, a scribe (or physician, etc.) may later playback the whole patient encounter, navigate (e.g., “clicking” a mouse cursor of other pointing device at any position) in any portion of any of the layers, make edits, and would know which edit/correction belongs to the other sections (layers). More generally, “clicking” (i.e. resetting the cursor) in one viewed layer may annotate and update the cursor in the linked points/excerpts in the other layers.
In some implementations, at least a portion of the audio encounter information determined to lack relevance to the medical report may be one of sped up and skipped 316 by ACD process 10. For example, in some implementations, it may be possible for the scribe to “playback” the whole encounter and see the draft medical report “emerge” (or simply see each associated report words highlighted, in sync with the cursor) so that they may ascertain which signals from the encounter caused/triggered which parts of the report, and react (e.g., correct/edit, etc.) accordingly. However, ACD process 10 may sped up or skip 316 the audio not only where no speech is detected by the ASR portion of ACD process 10, but also where the model (e.g., sequence to sequence/abstractive summarization, etc.) does not attribute any significant responsibility for the draft report to that excerpt of the conversation transcript's aligned audio (e.g., accumulated attribution across all outputs (e.g., medical report text) for an input (e.g., ASR word/excerpt) being below some threshold). For instance, assume for example purposes only that Mrs. Smith (i.e., the patient in this example) asks the Doctor about his golf game, which the Doctor spends about 30 seconds discussing. In the example, ACD process 10 may determine that the discussion of the Doctor's golf game is not relevant for the draft report to that excerpt of the conversation transcript's aligned audio, and may either skip or speed up (fast forward) through that portion of the audio (and the associated transcript).
Similarly, at least a portion of the audio encounter information determined to lack relevance to the medical report may be annotated 318 by ACD process 10. For instance, and referring to the example implementation of FIG. 8, UI 500 is shown. In the example, ACD process 10 may annotate 318 the portion of the audio encounter information (e.g., transcript and/or medical report) where the model (e.g., sequence to sequence/abstractive summarization, etc.) model does not attribute any significant responsibility for the draft report to that excerpt of the conversation transcript's aligned audio. For instance, assume for example purposes only that Mrs. Smith (i.e., the patient in this example) asks the Doctor “By the way, how has your golf game been lately?”, to which the Doctor replies “Oh it's been terrible. People are starting to call me “captain Hook!” In the example, ACD process 10 may determine that the discussion of the Doctor's golf game is not relevant for the draft report to that excerpt of the conversation transcript's aligned audio, and may annotate 318 (e.g., bold) that portion of the transcript. This may be especially advantageous for direct editing by a physician, who typically would not listen to the audio if reviewing/finalizing the report directly subsequent to the patient encounter. Thus, ACD process 10 may annotate 318 the subset of the transcript for which the model does not (significantly) attribute any portion of the medical report, allowing the physician to quickly scan for clinically relevant information potentially inadvertently missed by the model (e.g., not captured in some form in the report).
As discussed above, automated clinical documentation (ACD) process 10 may be configured to automate the collection and processing of clinical encounter information to generate/store/distribute medical records. Accordingly, as discussed above and referring also at least to FIG. 9, ACD process 10 may be configured to obtain 300 encounter information (e.g., machine vision encounter information 102 and/or audio encounter information 106) of a patient encounter (e.g., a visit to a doctor's office) of at least a first encounter participant, wherein the encounter information may include audio encounter information obtained from at least a first encounter participant (e.g., encounter participant 228, 226, 230, and/or 242). ACD process 10 may further be configured to process 302 the encounter information (e.g., machine vision encounter information 102 and/or audio encounter information 106) obtained from at least the first encounter participant, e.g., to generate an encounter transcript (e.g., encounter transcript 234) and/or generate 305 a user interface displaying a plurality of layers associated with the audio encounter information obtained from at least the first encounter participant, wherein at least one of the plurality of layers is one of exposed to the user interface and not exposed to the user interface based upon, at least in part, a confidence level. In some implementations, ACD process 10 may process at least a portion of the encounter transcript (e.g., encounter transcript 234) to populate at least a portion of a medical record/report (e.g., medical record 236) associated with the patient encounter (e.g., the visit to the doctor's office). Encounter transcript 234 and/or medical record 236 may be reviewed by a medical professional involved with the patient encounter (e.g., a visit to a doctor's office) to determine the accuracy of the same and/or make corrections to the same.
In some implementations, processing 302 the first audio encounter information may include defining 306 linkages between each of the plurality of layers associated with the audio encounter information. For example, the first layer of the plurality of layers may be a visualization and/or direct play-back of an audio signal associated with the audio encounter information (e.g., complete audio of the encounter, encompassing and clearly delineating each participant), wherein the second layer of the plurality of layers may be a transcript associated with the audio encounter information (e.g., a diarized audio transcript (verbatim) for each participant in the encounter), and wherein the third layer of the plurality of layers may be a medical report associated with the audio encounter information (e.g., a draft medical report in the appropriate clinical output format). In some implementations, additional layers may include, e.g., the above-noted machine vision-based recording of the encounter, including various signal formats and features, and discrete, standardized, actionable data resulting from the encounter, including, but not limited to medication plans (for example, in RxNorm) or lab orders (for example, LOINC) or diagnoses (for example, ICD10, CPT etc). In the example, the signals captured from the encounter information may be processed 304 into at least the above-noted three separate, yet closely linked and interdependent layers.
In some implementations, ACD process 10 may include an ASR portion that may process 302 the audio encounter information producing an approximate (e.g., diarized) verbatim transcript along with alignment information indicating the audio interval corresponding to each transcript word. In some implementations, a deep learning (e.g., sequence to sequence) model associated with ACD process 10 may convert the transcript to a medical report. It will be appreciated that various attribution techniques may be employed by ACD process 10 that may effectively softly assign responsibility for a given output (e.g., medical report) word to input (e.g., conversation transcript) words (e.g. attention weights, integrated gradient, etc.) according to the model. As a result, this may provide a soft mapping from the transcript word positions to report word positions. In some implementations, the input word position assigned maximal attribution for a given output word may be interpreted as being aligned (linked) to that output (e.g., when a hard mapping is required). Based on the ASR time alignment, a word in the draft medical report, aligned to a word in the ASR conversation transcript, may now be associated with an audio time interval of the associated audio signal of the audio encounter information.
In some implementations, ACD process 10 may also may link (i.e., align) the ASR conversation transcript words with the draft medical report words. For transcript words that may have maximal attribution value for some set of medical report words, ACD process 10 may link them with the first word in that set. For the remaining transcript words, ACD process 10 may link them to the same word that the nearest preceding (or if none, nearest subsequent) conversation transcript word is linked to. As a result, since each of the plurality of layers may be synchronized, a scribe (or physician, etc.) may later playback the whole patient encounter, navigate in any of the layers, make edits, and would know which edit/correction belongs to the other sections (layers).
In some implementations, a visual recording (e.g., video stream of the patient encounter), if available, may also be a layer and may be time indexed and thus a given point in the recording may be associated with the same time in the audio recording and thus a conversation transcript word and draft report word. In some implementations, if discrete, standardized, actionable data is produced as a second (parallel) output sequence of the sequence to sequence model, then a similar model output attribution technique may be used to align tokens in this actionable data with the ASR conversation transcript words, and thus the audio intervals.
In some implementations, ACD process 10 may generate 305 a user interface displaying a plurality of layers associated with the audio encounter information obtained from at least the first encounter participant, wherein at least one of the plurality of layers is one of exposed to the user interface and not exposed to the user interface based upon, at least in part, a confidence level. For example, and referring again at least to the example implementation of FIG. 5, an example user interface (e.g., user interface 500) is shown. It will be appreciated that UI 500 is shown merely for example purposes only, and that more or less features and arrangements of features may be used without departing from the scope of the present disclosure.
As can be seen from FIG. 5, UI 500 includes the first layer of the plurality of layers (e.g., first layer 502 which may be a visualization and/or direct play-back of an audio signal associated with the audio encounter information (e.g., complete audio of the encounter, encompassing and clearly delineating each participant), second layer 504 of the plurality of layers which may be a transcript (e.g., encounter transcript 234) associated with the audio encounter information (e.g., a diarized audio transcript (verbatim) for each participant in the encounter), and third layer 506 of the plurality of layers which may be a medical report (e.g., medical report/record 236) associated with the audio encounter information (e.g., a draft medical report in the appropriate clinical output format). It will be appreciated that that each layer (audio, transcript, draft report, etc.) may be rendered in multiple different ways, and in the most appropriate way for a given use/preference of the end-user. As such, the specific rendering of layers should be taken as example only and not to limit the scope of the disclosure.
As noted above, encounter transcript 234 (via second layer 504) and/or medical record/record 236 (via third layer 506) may be reviewed by a medical professional involved with the patient encounter (e.g., a visit to a doctor's office) to determine the accuracy of the same and/or make corrections to the same. For example, a scribe involved with (or assigned to) the patient encounter (e.g., a visit to a doctor's office) may review encounter transcript 234 and/or medical record 236 to confirm that the same was accurate and/or make corrections to the same. In the event that corrections are made to encounter transcript 234 and/or medical record 236, automated clinical documentation process 10 may utilize these corrections for training/tuning purposes (e.g., to adjust the various profiles associated the participants of the patient encounter) to enhance the future accuracy/efficiency/performance of automated clinical documentation process 10.
Alternatively/additionally, a doctor involved with the patient encounter (e.g., a visit to a doctor's office) may review encounter transcript 234 and/or medical record 236 to confirm that the same was accurate and/or make corrections to the same. In the event that corrections are made to encounter transcript 234 and/or medical record 236, automated clinical documentation process 10 may utilize these corrections for training/tuning purposes (e.g., to adjust the various profiles associated the participants of the patient encounter) to enhance the future accuracy/efficiency/performance of automated clinical documentation process 10.
As noted above, at least one of the plurality of layers is one of exposed to the user interface and not exposed to the user interface based upon, at least in part, a confidence level. For example, ACD process 10 may employ a confidence model that may only expose (e.g., display) at least one layer (e.g., the medical report layer 506 or a section of the medical report layer section) to the user interface if ACD process 10 (via the confidence model) determines there is sufficient confidence, such as a threshold confidence level, that the draft report (or draft report section) will be faster than being typed from scratch. For instance, exposing (e.g., displaying) the medical report/section to UI 500 (e.g., for editing) may enable the ability to change some incorrectly labeled terms/sentences, which may be faster than manually typing out the entire section from the beginning; however, if so many terms/sentences are incorrect (and therefore need to be changed), it may be faster to simply type out the entire section from the beginning, rather than making substantial changes to the draft report section. As such, in the example where ACD process 10 determines an estimated time that it will take to make corrections compared to an estimated time that it will take to type out the entire section from the beginning, and determines it may be faster to simply type out the entire section from the beginning (rather than make corrections), ACD process 10 may not display the report/section by not exposing the report/section to UI 500 in the first place. In some implementations, the use of the confidence level for exposure may be only for outputs expected to be part of the actual case record, e.g., the medical report layer and the optionally concurrently generated discrete/actionable structured data. In some implementations, the decision to expose or not expose may be per section of the medical report (or structured data), e.g., Exam section (report) or Lab Orders (structured), etc.
In some implementations, ACD process 10 may leverage various features of the confidence model, including the statistics (e.g., min, max, standard deviation, etc.) of the difference in probability between the first and second most likely word hypothesized at each position in the report/section via, e.g., a model (e.g., sequence to sequence model), the log likelihood of the draft report/section per the model (e.g., in addition to a length normalized version of this), confidence values from the ASR portion of ACD process 10 (e.g., particularly for segments to which the report/section content is attributed) and information regarding the typical (e.g., mean/standard deviation) number of edits required for a relevant physician and typical number of edits made by a relevant scribe. For draft reports/sections that ACD process 10 may actually expose to be edited (rather than typed from scratch), ACD process 10 may collect the number of edits made and time required to make them, which may be added to training and improvement of the confidence model over time.
For example, in some implementations, ACD process 10 may train 408 a model that maps the transcript to the medical report from pairs of prior transcripts and medical reports. For instance, the core model (e.g., sequence to sequence model) of ACD process 10 that may map the conversation transcript to the medical reports may be trained 408 from pairs of (e.g., ASR approximate) transcripts and medical reports. For example, as additional reports are generated/edited/typed by scribes/physicians, these additional reports may be automatically (or manually) added to the training pool for the sequence to sequence model, which may be automatically intermittently retrained. In some implementations, the model may be metadata-dependent (e.g., physician, institution, scribe, etc.), either by (e.g., regularized) adaptation to appropriate subsets of the training pool or by using this metadata as inputs or combination thereof. That is, the training pool may be specific to the user, type of user, or institution of the user making the changes to the medical report. In some implementations, the number and types of edits made by the scribe (or other user) may also be used by the confidence model to better predict the number of edits (and thus editing efficiency) for subsequent drafts.
In some implementations, e.g., towards the end of the patient encounter, as the confidence of the information regarding the medical report section rises, more items may be documented (e.g., added) in this section. For instance, assume for example purposes only that one of the encounter participants (e.g., the physician) mentions “examination.” Using the techniques described above, ACD process 10 may recognize this fact, and may display some associated points about the physical examinations under the “Examination” section (e.g., in the medical report layer 506 shown at least in FIG. 5), which may be first grayed. In the example, as the physician continues to verbalize further associated points that make the confidence level of what was entered into the Examination section higher, the greyed points may become solid, and further adjustments/edits may be made by ACD process 10 shortly thereafter (e.g., in the following seconds). Similarly, related to the “Assessment/Plan” section (e.g., in the medical report layer 506) after the physician verbalizes his assessment, ACD process 10 may start documenting that section, first grayed, but then the grayed words may become more solid (e.g., darker or normal solid color) with more points being added as ACD process 10 knows more and the confidence level rises. In some implementations, showing the transition from grey to solid wording may help train scribes (or other users) to use ACD process 10 and recognize how it works.
In some implementations, ACD process 10 may update 410 an output of the user interface based upon, at least in part, one or more modifications made at least one layer of the plurality of layers. For instance, rather than the output being static during the editing process, ACD process 10 may update 410 the output based on the modifications made by the editor so far (e.g., based on the decoder being autoregressive in nature). In particular, the decoder (e.g., sequence to sequence decoder) output may depend on its preceding output. As such, if the scribe (or other user) makes a correction in one part of the draft report, ACD process 10 may update a best guess at the subsequent content. In some implementations, this may be distracting to the user, and so to make it less distracting, it may be optionally limited to a toggle-able mode (e.g., online/synchronous vs. global review mode) and/or limited to only modifying the draft output for subsequent sections of the report. In some implementations, there may be at least four ways that corrections to case-record-persistent system outputs (e.g., medical reports, structured data) may be utilized. For example, pairs of ASR transcripts and corrected reports may be used for offline (sequence to sequence, transcript->report) model training. If in the typing acceleration mode as opposed to draft-report-correction mode, as the user types, the prediction for next sentence may be updated, which may not be model training/adaptation, but rather a reflection of the (auto-regressive) model predicting next output based on report content so far. If in the draft-report-correction mode, as the user makes corrections, prediction of subsequent content (sentences or perhaps less distracting, sections) and thus the draft report content (in this report) may be updated, again utilizing the same auto-regressive nature of the sequence to sequence model (and not some result of model training). Tuples of ASR transcripts (along with ASR confidence information), draft reports and noted user edits (e.g., corrections) may be used for an offline confidence model (e.g., required number of edits) training.
In some implementations, ACD process 10 may update 412 a prediction for a next sentence to be typed based upon, at least in part, current content of at least one layer of the plurality of layers, where in some implementations, the at least one layer of the plurality of layers may be the medical report. For example, for reports that the above-noted confidence model (via ACD process 10) determines are best typed from scratch rather than editing a draft, ACD process 10 may leverage the summarization model to accelerate composition by having it predict the next sentence to type and updating that prediction based on, and to be consistent with, what the scribe (or other user) has typed so far. For instance, ACD process 10 (e.g., via UI 500) may allow the user to select the model's prediction of the current/next sentence being presented to the user in the report by selecting the tab key (or other shortcut) to complete the sentence (e.g., auto-completion based typing accelerant). In this way, ACD process 10 (e.g., via the model) may only predict the draft report a sentence at a time based on the scribes typing/feedback. In some implementations, the prediction may be based not just upon what the scribe is currently writing, but may additionally (or alternatively) be based upon the context of what the scribe has previous written in previous sentences of the report (or based upon a training pool specific to the scribe). In some implementations, the sentence prediction may be based on the same model that produces the draft medical report. In some implementations, when based on the confidence model and it is decided to suppress the draft medical report (section), the ACD process 10 based auto-completion typing accelerant may allow the salvage of some efficiency improvement.
As discussed above, automated clinical documentation (ACD) process 10 may be configured to automate the collection and processing of clinical encounter information to generate/store/distribute medical records. Accordingly and referring also at least to FIGS. 10-11, ACD process 10 may be configured to obtain 300 encounter information (e.g., machine vision encounter information 102 and/or audio encounter information 106) of a patient encounter (e.g., a visit to a doctor's office) of at least a first encounter participant, wherein the encounter information may include audio encounter information obtained from at least a first encounter participant (e.g., encounter participant 228, 226, 230, and/or 242). ACD process 10 may further be configured to process 302 the encounter information (e.g., machine vision encounter information 102 and/or audio encounter information 106) obtained from at least the first encounter participant, e.g., to generate an encounter transcript (e.g., encounter transcript 234) and/or generate 304 a user interface displaying a plurality of layers associated with the audio encounter information obtained from at least the first encounter participant. In some implementations, ACD process 10 may receive 307 a user input from a peripheral device to navigate through each of the plurality of layers associated with the audio encounter information displayed on the user interface. In some implementations, ACD process 10 may process at least a portion of the encounter transcript (e.g., encounter transcript 234) to populate at least a portion of a medical record (e.g., medical record 236) associated with the patient encounter (e.g., the visit to the doctor's office). Encounter transcript 234 and/or medical record 236 may be reviewed by a medical professional involved with the patient encounter (e.g., a visit to a doctor's office) to determine the accuracy of the same and/or make corrections to the same.
As noted above, ACD process 10 may process 302 the audio encounter information obtained from at least the first encounter participant. In some implementations, processing 302 the first audio encounter information may include defining 306 linkages between each of the plurality of layers associated with the audio encounter information. For example, the first layer of the plurality of layers may be a visualization and/or direct play-back of an audio signal associated with the audio encounter information (e.g., complete audio of the encounter, encompassing and clearly delineating each participant), wherein the second layer of the plurality of layers may be a transcript associated with the audio encounter information (e.g., a diarized audio transcript (verbatim) for each participant in the encounter), and wherein the third layer of the plurality of layers may be a medical report associated with the audio encounter information (e.g., a draft medical report in the appropriate clinical output format). In some implementations, additional layers may include, e.g., the above-noted machine vision-based recording of the encounter, including various signal formats and features, and discrete, standardized, actionable data resulting from the encounter, including, but not limited to medication plans (for example, in RxNorm) or lab orders (for example, LOINC) or diagnoses (for example, ICD10, CPT etc). In the example, the signals captured from the encounter information may be processed 304 into at least the above-noted three separate, yet closely linked and interdependent layers.
In some implementations, ACD process 10 may include an ASR portion that may process 302 the audio encounter information producing an approximate (e.g., diarized) verbatim transcript along with alignment information indicating the audio interval corresponding to each transcript word. In some implementations, a deep learning (e.g., sequence to sequence) model associated with ACD process 10 may convert the transcript to a medical report. It will be appreciated that various attribution techniques may be employed by ACD process 10 that may effectively softly assign responsibility for a given output (e.g., medical report) word to input (e.g., conversation transcript) words (e.g. attention weights, integrated gradient, etc.) according to the model. As a result, this may provide a soft mapping from the transcript word positions to report word positions. In some implementations, the input word position assigned maximal attribution for a given output word may be interpreted as being aligned (linked) to that output (e.g., when a hard mapping is required). Based on the ASR time alignment, a word in the draft medical report, aligned to a word in the ASR conversation transcript, may now be associated with an audio time interval of the associated audio signal of the audio encounter information.
In some implementations, ACD process 10 may also may link (i.e., align) the ASR conversation transcript words with the draft medical report words. For transcript words that may have maximal attribution value for some set of medical report words, ACD process 10 may link them with the first word in that set. For the remaining transcript words, ACD process 10 may link them to the same word that the nearest preceding (or if none, nearest subsequent) conversation transcript word is linked to.
In some implementations, a visual recording (e.g., video stream of the patient encounter), if available, may also be a layer and may be time indexed and thus a given point in the recording may be associated with the same time in the audio recording and thus a conversation transcript word and draft report word. In some implementations, if discrete, standardized, actionable data is produced as a second (parallel) output sequence of the sequence to sequence model, then a similar model output attribution technique may be used to align tokens in this actionable data with the ASR conversation transcript words, and thus the audio intervals.
In some implementations, ACD process 10 may generate 304 a user interface displaying a plurality of layers associated with the audio encounter information obtained from at least the first encounter participant. For example, and referring again at least to the example implementation of FIG. 5, an example user interface (e.g., user interface 500) is shown. It will be appreciated that UI 500 is shown merely for example purposes only, and that more or less features and arrangements of features may be used without departing from the scope of the present disclosure.
As can be seen from FIG. 5, UI 500 includes the first layer of the plurality of layers (e.g., first layer 502 which may be a visualization and/or direct play-back of an audio signal associated with the audio encounter information (e.g., complete audio of the encounter, encompassing and clearly delineating each participant), second layer 504 of the plurality of layers which may be a transcript (e.g., encounter transcript 234) associated with the audio encounter information (e.g., a diarized audio transcript (verbatim) for each participant in the encounter), and third layer 506 of the plurality of layers which may be a medical report (e.g., medical report/record 236) associated with the audio encounter information (e.g., a draft medical report in the appropriate clinical output format). It will be appreciated that that each layer (audio, transcript, draft report, etc.) may be rendered in multiple different ways, and in the most appropriate way for a given use/preference of the end-user. As such, the specific rendering of layers should be taken as example only and not to limit the scope of the disclosure.
As noted above, encounter transcript 234 (via second layer 504) and/or medical record/record 236 (via third layer 506) may be reviewed by a medical professional involved with the patient encounter (e.g., a visit to a doctor's office) to determine the accuracy of the same and/or make corrections to the same. For example, a scribe involved with (or assigned to) the patient encounter (e.g., a visit to a doctor's office) may review encounter transcript 234 and/or medical record 236 to confirm that the same was accurate and/or make corrections to the same. In the event that corrections are made to encounter transcript 234 and/or medical record 236, automated clinical documentation process 10 may utilize these corrections for training/tuning purposes (e.g., to adjust the various profiles associated the participants of the patient encounter) to enhance the future accuracy/efficiency/performance of automated clinical documentation process 10.
Alternatively/additionally, a doctor involved with the patient encounter (e.g., a visit to a doctor's office) may review encounter transcript 234 and/or medical record 236 to confirm that the same was accurate and/or make corrections to the same. In the event that corrections are made to encounter transcript 234 and/or medical record 236, automated clinical documentation process 10 may utilize these corrections for training/tuning purposes (e.g., to adjust the various profiles associated the participants of the patient encounter) to enhance the future accuracy/efficiency/performance of automated clinical documentation process 10.
Therefore, and referring at least to the example implementation of FIG. 11, to help review encounter transcript 234 and/or medical record 236 to confirm that the same was accurate and/or make corrections to the same, in some implementations, ACD process 10 may receive 307 a user input from a peripheral device to navigate through each of the plurality of layers associated with the audio encounter information displayed on the user interface. In some implementations, the peripheral device may include, e.g., a keyboard (e.g., keyboard 1100), a pointing device (e.g., mouse 1102), a foot pedal (e.g., foot pedal 1104), a dial (e.g., dial 1106), or combination thereof. It will be appreciated that other peripheral devices may be used without departing from the scope of the present disclosure. One or more of the peripheral devices may be physically or wirelessly connected to the computing device displaying UI 500.
As such, and referring again at least to the example implementation of FIG. 6, assume for example purposes only that a scribe is reviewing the encounter information using UI 500. In some implementations, receiving 307 the user input from the peripheral device may include receiving 309, via the user input from the peripheral device, a selection of a first portion of the audio encounter information at a first layer of the plurality of layers on the user interface, and ACD process 10 may display 310 an annotation of at least one of a second layer of the plurality of layers and a third layer of the plurality of layers corresponding to the first portion of the audio encounter information of the first layer of the plurality of layers selected on the user interface. For instance, the scribe may use, e.g., any of the example peripheral devices, to select a portion of first layer 502 (i.e., the audio information of the audio encounter information), which may be received 309 by ACD process 10. As a result, in some implementations, ACD process 10 may display 310 some kind of annotation of either the second layer (e.g., the portion of the transcript associated with the selected portion of the first layer) and/or the third layer (e.g., the portion of the medical report associated with the selected portion of the first layer). In the example, ACD process 10 has displayed an annotation (e.g., bold font) of the second layer (e.g., the portion of the transcript associated with the selected portion of the first layer) and the third layer (e.g., the portion of the medical report associated with the selected portion of the first layer). It will be appreciated that any type of annotation may be used (e.g., bold, italics, underline, highlights, shading, transparency, etc.) without departing from the scope of the present disclosure. As such, the use of bolding as the annotation should be taken as example only and not to otherwise limit the scope of the disclosure.
Similarly, in some implantations, receiving 307 the user input from the peripheral device may include receiving 313, via the user input from the peripheral device, a selection of the first portion of the audio encounter information at one of the second layer of the plurality of layers and the third layer of the plurality of layers on the user interface, and ACD process 10 may provide 314 audio of the first layer corresponding to the first portion of the audio encounter information of one of the second layer of the plurality of layers and the third layer of the plurality of layers selected on the user interface. For example, and referring again at least to the example implementation of FIG. 7, the scribe may use, e.g., any of the example peripheral devices, to select a portion of second layer 504 (e.g., the transcript), and/or the third layer (e.g., the medical report) which may be received 312 by ACD process 10. As a result, in some implementations, ACD process 10 may provide 314 the audio of first layer 502 (e.g., the audio information of the audio encounter associated with the selected portion of second layer 504).
As noted above, the physician (or scribe) may need to verify the correctness of the medical report created by ACD process 10. This may involve, e.g., checking for correctness of each sentence/word in the medical report generated by looking for evidence in the conversation transcript (attribution), checking the correctness of the conversational transcript generated by an ASR) by listening to the audio segment. The use of dedicated hardware (e.g., a peripheral device) may be utilized by ACD process 10 to improve editing efficiency for medical transcriptionists/physicians, etc. to help navigate and browse (e.g., sentence by sentence) through the draft medical report, the associated conversation transcript excerpt, and/or associated audio file, annotated (e.g., highlighted, bolded, etc.) with its corresponding audio cued up for easy playback.
For example, in some implementations, the user input from the peripheral device may include a keyboard shortcut when the peripheral device is keyboard 1100. For example, default and/or user defined keyboard shortcuts may be used to interact with UI 500. For instance, a combination of keys (e.g., control+shift+S) may execute a particular command for UI 500. For instance, such a shortcut may cause UI 500 to, e.g., switch between sentences in an output of the medical report, switch between sections in the output of the medical report, switch between the medical report and the transcript, provide/playback audio of the audio signal, cease/stop playback of the audio of the audio signal, speeding up playback of the audio of the audio signal, or slow down playback of the audio of the audio signal. It will be appreciated that various other keyboard shortcuts, as well as single key inputs (e.g., arrows, spacebar, etc.) may execute the above-noted commands for UI 500 without departing from the scope of the disclosure.
In some implementations, the user input from the peripheral device may include a pointing device action when the peripheral device is pointing device 1102. For example, default and/or user defined mouse actions may be used to interact with UI 500. For instance, movement of the mouse cursor over a particular portion of one of the above-noted layers, clicking or double clicking on a particular portion of one of the above-noted layers, hovering over a particular portion of one of the above-noted layers, using a scroll wheel of the mouse, etc. may execute a particular command for UI 500. For instance, any one of the example uses of the mouse may cause UI 500 to, e.g., switch between sentences in an output of the medical report, switch between sections in the output of the medical report, switch between the medical report and the transcript, provide/playback audio of the audio signal, cease/stop playback of the audio of the audio signal, speeding up playback of the audio of the audio signal, or slow down playback of the audio of the audio signal. It will be appreciated that various other keyboard shortcuts, as well as single key inputs (e.g., arrows, spacebar, etc.) may execute the above-noted commands for UI 500 without departing from the scope of the disclosure.
In some implementations, the user input from the peripheral device may include raising and lowering of the foot pedal when the peripheral device is foot pedal 1104. For example, default and/or user defined foot pedal actions may be used to interact with UI 500. For instance, raising and lowering of the foot pedal (similar to how the foot pedal in a vehicle may function) may execute a particular command for UI 500. For instance, lowering the pedal (e.g., using the user's foot to press down on pedal 1104) may cause UI 500 to, e.g., provide/playback audio of the audio signal, and may speed up playback of the audio of the audio signal depending on the amount the pedal is lowered. Conversely, raising the pedal (e.g., lifting the user's foot off the pedal 1104) may cause UI 500 to, e.g., cease/stop playback of the audio of the audio signal, and may or slow down playback of the audio of the audio signal depending on the amount the pedal is raised.
In some implementations, the user input from the peripheral device may include at least one of a rotating action, an up action, a down action, a left action, a right action, and a pressing action of the dial when the peripheral device is dial 1106. For example, default and/or user defined dial actions may be used to interact with UI 500. For instance, UI 500 (via ACD process 10) may switch the focus between sentences in the output medical report by rotating the dial, e.g., one click clockwise may move the focus to the next sentence and counter clockwise may move the focus to the previous sentence. As another example, UI 500 (via ACD process 10) may switch the focus between different sections of the medical report using the up/down arrows on dial 1106. Similarly, as discussed above at least with regard to FIGS. 6 and 7, evidence in conversational transcripts for the selected sentence in the report/transcript may be annotated (e.g., highlighted, bolded, etc.). Evidence may include a word or phrase or sentence and may be obtained from attention weights (e.g., byproduct of a sequence to sequence based summarization system) or other dedicated models for attribution. As another example, UI 500 (via ACD process 10) may switch focus from the medical report to the conversational transcript using, e.g., left/right arrows on dial 1106. As another example, UI 500 (via ACD process 10) may browse may switch the focus between sentences in the transcript by rotating the dial, e.g., one click clockwise may move the focus to the next sentence and counter clockwise may move the focus to the previous sentence. As yet another example, UI 500 (via ACD process 10) may, when the annotated sentence in the transcript is selected by pressing dial 1106, play back the corresponding audio chunk (e.g., identified by time stamps from the ASR decoding).
It will be appreciated that any of the example peripheral devices may be used in any combination with each other's functions without departing from the scope of the disclosure. For example, using pointing device 1102 to hover over a particular portion of the transcript, medical report section, or audio signal may be the starting location where, the functions of e.g., dial 1106 may be used. As such, the use of any particular peripheral device and its particular function should be taken as example only and not to otherwise limit the scope of the disclosure.
As such, ACD process 10 may leverage the above-noted defined linkages and peripheral devices, such that the encounter recording as captured above may be provided to a human scribe (or physician) in such a fashion, so that they may navigate through each of these layers independently and be always in sync. For instance, if the scribe navigates through first layer 502 (audio) by listening, the part of the transcript that corresponds to that part of the audio may be bolded, highlighted, etc. accordingly, as well as the resulting medical report (and if relevant actionable data) from that information. Additionally/alternatively, if the scribe selects a part of the report, the audio/transcript sections that affected that part of the report may be bolded, highlighted, emphasized, etc. This annotation also may correspond to the audio and report “cursor” (e.g., audio cursor 510) moving, e.g., audio may next play from that position and typing/keyboard-navigation may commence from that position in the report. As a result, since each of the plurality of layers may be synchronized, a scribe (or physician, etc.) may later playback the whole patient encounter, navigate (e.g., “clicking” a mouse cursor of other pointing device at any position) in any portion of any of the layers, make edits, and would know which edit/correction belongs to the other sections (layers). More generally, “clicking” (i.e. resetting the cursor) in one viewed layer may annotate and update the cursor in the linked points/excerpts in the other layers.
As discussed above, automated clinical documentation (ACD) process 10 may be configured to automate the collection and processing of clinical encounter information to generate/store/distribute medical records. Accordingly, as discussed above and referring also at least to FIGS. 12-14, ACD process 10 may be configured to obtain 300 encounter information (e.g., machine vision encounter information 102 and/or audio encounter information 106) of a patient encounter (e.g., a visit to a doctor's office) of at least a first encounter participant, wherein the encounter information may include audio encounter information obtained from at least a first encounter participant (e.g., encounter participant 228, 226, 230, and/or 242). ACD process 10 may further be configured to process 302 the encounter information (e.g., machine vision encounter information 102 and/or audio encounter information 106) obtained from at least the first encounter participant, e.g., to generate an encounter transcript (e.g., encounter transcript 234) and/or generate 505 a user interface displaying a plurality of layers associated with the audio encounter information obtained from at least the first encounter participant, wherein at least a portion of one of the plurality of layers is added to a section of the one of the plurality of layers based upon, at least in part, a confidence level. In some implementations, ACD process 10 may process at least a portion of the encounter transcript (e.g., encounter transcript 234) to populate at least a portion of a medical record/report (e.g., medical record 236) associated with the patient encounter (e.g., the visit to the doctor's office). Encounter transcript 234 and/or medical record 236 may be reviewed by a medical professional involved with the patient encounter (e.g., a visit to a doctor's office) to determine the accuracy of the same and/or make corrections to the same.
In some implementations, processing 302 the first audio encounter information may include defining 306 linkages between each of the plurality of layers associated with the audio encounter information. For example, the first layer of the plurality of layers may be a visualization and/or direct play-back of an audio signal associated with the audio encounter information (e.g., complete audio of the encounter, encompassing and clearly delineating each participant), wherein the second layer of the plurality of layers may be a transcript associated with the audio encounter information (e.g., a diarized audio transcript (verbatim) for each participant in the encounter), and wherein the third layer of the plurality of layers may be a medical report associated with the audio encounter information (e.g., a draft medical report in the appropriate clinical output format). In some implementations, additional layers may include, e.g., the above-noted machine vision-based recording of the encounter, including various signal formats and features, and discrete, standardized, actionable data resulting from the encounter, including, but not limited to medication plans (for example, in RxNorm) or lab orders (for example, LOINC) or diagnoses (for example, ICD10, CPT etc). In the example, the signals captured from the encounter information may be processed 304 into at least the above-noted three separate, yet closely linked and interdependent layers.
In some implementations, ACD process 10 may include an ASR portion that may process 302 the audio encounter information producing an approximate (e.g., diarized) verbatim transcript along with alignment information indicating the audio interval corresponding to each transcript word. In some implementations, a deep learning (e.g., sequence to sequence) model associated with ACD process 10 may convert the transcript to a medical report. It will be appreciated that various attribution techniques may be employed by ACD process 10 that may effectively softly assign responsibility for a given output (e.g., medical report) word to input (e.g., conversation transcript) words (e.g. attention weights, integrated gradient, etc.) according to the model. As a result, this may provide a soft mapping from the transcript word positions to report word positions. In some implementations, the input word position assigned maximal attribution for a given output word may be interpreted as being aligned (linked) to that output (e.g., when a hard mapping is required). Based on the ASR time alignment, a word in the draft medical report, aligned to a word in the ASR conversation transcript, may now be associated with an audio time interval of the associated audio signal of the audio encounter information.
In some implementations, ACD process 10 may also may link (i.e., align) the ASR conversation transcript words with the draft medical report words. For transcript words that may have maximal attribution value for some set of medical report words, ACD process 10 may link them with the first word in that set. For the remaining transcript words, ACD process 10 may link them to the same word that the nearest preceding (or if none, nearest subsequent) conversation transcript word is linked to. As a result, since each of the plurality of layers may be synchronized, a scribe (or physician, etc.) may later playback the whole patient encounter, navigate in any of the layers, make edits, and would know which edit/correction belongs to the other sections (layers).
In some implementations, a visual recording (e.g., video stream of the patient encounter), if available, may also be a layer and may be time indexed and thus a given point in the recording may be associated with the same time in the audio recording and thus a conversation transcript word and draft report word. In some implementations, if discrete, standardized, actionable data is produced as a second (parallel) output sequence of the sequence to sequence model, then a similar model output attribution technique may be used to align tokens in this actionable data with the ASR conversation transcript words, and thus the audio intervals.
As noted above, in some implementations, ACD process 10 may generate a user interface displaying a plurality of layers associated with the audio encounter information obtained from at least the first encounter participant. For example, and referring again at least to the example implementation of FIG. 5, an example user interface (e.g., user interface 500) is shown. It will be appreciated that UI 500 is shown merely for example purposes only, and that more or less features and arrangements of features may be used without departing from the scope of the present disclosure.
As can be seen from FIG. 5, UI 500 includes the first layer of the plurality of layers (e.g., first layer 502 which may be a visualization and/or direct play-back of an audio signal associated with the audio encounter information (e.g., complete audio of the encounter, encompassing and clearly delineating each participant), second layer 504 of the plurality of layers which may be a transcript (e.g., encounter transcript 234) associated with the audio encounter information (e.g., a diarized audio transcript (verbatim) for each participant in the encounter), and third layer 506 of the plurality of layers which may be a medical report (e.g., medical report/record 236) associated with the audio encounter information (e.g., a draft medical report in the appropriate clinical output format). It will be appreciated that that each layer (audio, transcript, draft report, etc.) may be rendered in multiple different ways, and in the most appropriate way for a given use/preference of the end-user. As such, the specific rendering of layers should be taken as example only and not to limit the scope of the disclosure.
As noted above, encounter transcript 234 (via second layer 504) and/or medical record/record 236 (via third layer 506) may be reviewed by a medical professional involved with the patient encounter (e.g., a visit to a doctor's office) to determine the accuracy of the same and/or make corrections to the same. For example, a scribe involved with (or assigned to) the patient encounter (e.g., a visit to a doctor's office) may review encounter transcript 234 and/or medical record 236 to confirm that the same was accurate and/or make corrections to the same. In the event that corrections are made to encounter transcript 234 and/or medical record 236, automated clinical documentation process 10 may utilize these corrections for training/tuning purposes (e.g., to adjust the various profiles associated the participants of the patient encounter) to enhance the future accuracy/efficiency/performance of automated clinical documentation process 10.
Alternatively/additionally, a doctor involved with the patient encounter (e.g., a visit to a doctor's office) may review encounter transcript 234 and/or medical record 236 to confirm that the same was accurate and/or make corrections to the same. In the event that corrections are made to encounter transcript 234 and/or medical record 236, automated clinical documentation process 10 may utilize these corrections for training/tuning purposes (e.g., to adjust the various profiles associated the participants of the patient encounter) to enhance the future accuracy/efficiency/performance of automated clinical documentation process 10.
As noted above, at least one of the plurality of layers may be one of exposed to the user interface and not exposed to the user interface based upon, at least in part, a confidence level. For example, ACD process 10 may employ a confidence model that may only expose (e.g., display) at least one layer (e.g., the medical report layer 506 or a section of the medical report layer section) to the user interface if ACD process 10 (via the confidence model) determines there is sufficient confidence, such as a threshold confidence level, that the draft report (or draft report section) will be faster than being typed from scratch. For instance, exposing (e.g., displaying) the medical report/section to UI 500 (e.g., for editing) may enable the ability to change some incorrectly labeled terms/sentences, which may be faster than manually typing out the entire section from the beginning; however, if so many terms/sentences are incorrect (and therefore need to be changed), it may be faster to simply type out the entire section from the beginning, rather than making substantial changes to the draft report section. As such, in the example where ACD process 10 determines an estimated time that it will take to make corrections compared to an estimated time that it will take to type out the entire section from the beginning, and determines it may be faster to simply type out the entire section from the beginning (rather than make corrections), ACD process 10 may not display the report/section by not exposing the report/section to UI 500 in the first place.
In some implementations, ACD process 10 may leverage various features of the confidence model, including the statistics (e.g., min, max, standard deviation, etc.) of the difference in probability between the first and second most likely word hypothesized at each position in the report/section via, e.g., a model (e.g., sequence to sequence model), the log likelihood of the draft report/section per the model (e.g., in addition to a length normalized version of this), confidence values from the ASR portion of ACD process 10 (e.g., particularly for segments to which the report/section content is attributed) and information regarding the typical (e.g., mean/standard deviation) number of edits required for a relevant physician and typical number of edits made by a relevant scribe. For draft reports/sections that ACD process 10 may actually expose to be edited (rather than typed from scratch), ACD process 10 may collect the number of edits made and time required to make them, which may be added to training and improvement of the confidence model over time.
For example, in some implementations, ACD process 10 may train 408 a model that maps the transcript to the medical report from pairs of prior transcripts and medical reports. For instance, the core model (e.g., sequence to sequence model) of ACD process 10 that may map the conversation transcript to the medical reports may be trained 408 from pairs of (e.g., ASR approximate) transcripts and medical reports. For example, as additional reports are generated/edited/typed by scribes/physicians, these additional reports may be automatically (or manually) added to the training pool for the sequence to sequence model, which may be automatically intermittently retrained. In some implementations, the model may be metadata-dependent (e.g., physician, institution, scribe, etc.), either by (e.g., regularized) adaptation to appropriate subsets of the training pool or by using this metadata as inputs or combination thereof. That is, the training pool may be specific to the user, type of user, or institution of the user making the changes to the medical report. In some implementations, the number and types of edits made by the scribe (or other user) may also be used by the confidence model to better predict the number of edits (and thus editing efficiency) for subsequent drafts.
As noted above, in some implementations, ACD process 10 generate 505 UI 500 displaying the plurality of layers associated with the audio encounter information obtained from at least the first encounter participant, and in some implementations, ACD process 10 may annotate 509 at least the portion of the one of the plurality of layers added to the section of the one of the plurality of layers based upon, at least in part, the confidence level. For example, in some implementations, e.g., during a patient encounter, toward the end of the patient encounter, or during scribe training during playback, as the confidence of the information regarding the medical report section rises, more items may be documented (e.g., added) in this section. For instance, assume for example purposes only that one of the encounter participants (e.g., the physician) mentions “assessment” or “plan” or alternatively ACD process 10 may use NLU to determine from the conversational transcript 234 that the context of what the physician is saying (e.g., “and come back for a follow up in two weeks”) may apply to the “Assessment/Plan” section (e.g., in medical report layer 506) of medical report 236. Using the techniques described above, ACD process 10 may recognize this, and may add (display) some associated points about the recommendation under the “Assessment/Plan” section (e.g., in the medical report layer 506 shown at least in the example implementation of UI 500 in FIG. 13), which may be first added and grayed based upon a first confidence level of what was said. That is, “recommending she come back for a follow up in 2 weeks” (shown at portion 1300 a) may be first be added and grayed based upon the first confidence level being below a threshold confidence level. In the example, and referring at least to the example implementation of UI 500 shown in FIG. 14, as the physician continues to verbalize further associated points of what was respectively entered into the Assessment/Plan section, which therefore makes the confidence level (e.g., an updated confidence level above the threshold confidence level) of what was entered become higher, some of the grayed points (e.g., “recommending she come back” shown at portion 1300 b) associated with the higher confidence level may be annotated (e.g., become solid or other type of annotation), or further adjustments/edits may be made by ACD process 10 shortly thereafter (e.g., in the following seconds) to correct the grayed portion based on the confidence level now taking into account the additional context of the further verbalization, which may then become solid. As such, after the physician verbalizes his assessment, ACD process 10 may start documenting that section, first grayed, but then the grayed words may become more solid (e.g., darker or normal solid color) with more points being added and becoming more solid as ACD process 10 knows more and the confidence level of what was said rises. In some implementations, showing the transition from gray to solid (or other annotation) wording may help train scribes (or other users) to use ACD process 10 and recognize how it works; however, it will be appreciated that the annotation of wording based upon confidence level may occur at any stage of the patient encounter and/or post patient encounter during scribe/physician playback/editing.
In some implementations, ACD process 10 may update 410 an output of the user interface based upon, at least in part, one or more modifications made at least one layer of the plurality of layers. For instance, rather than the output being static during the editing process, ACD process 10 may update 410 the output based on the modifications made by the editor so far (e.g., based on the decoder being autoregressive in nature). In particular, the decoder (e.g., sequence to sequence decoder) output may depend on its preceding output. As such, if the scribe (or other user) makes a correction in one part of the draft report, ACD process 10 may update a best guess at the subsequent content. In some implementations, this may be distracting to the user, and so to make it less distracting, it may be optionally limited to a toggle-able mode (e.g., online/synchronous vs. global review mode) and/or limited to only modifying the draft output for subsequent sections of the report.
In some implementations, ACD process 10 may update 412 a prediction for a next sentence to be typed based upon, at least in part, current content of at least one layer of the plurality of layers, where in some implementations, the at least one layer of the plurality of layers may be the medical report. For example, for reports that the above-noted confidence model (via ACD process 10) determines are best typed from scratch rather than editing a draft, ACD process 10 may leverage the summarization model to accelerate composition by having it predict the next sentence to type and updating that prediction based on, and to be consistent with, what the scribe (or other user) has typed so far. For instance, ACD process 10 (e.g., via UI 500) may allow the user to select the model's prediction of the current/next sentence being presented to the user in the report by selecting the tab key (or other shortcut) to complete the sentence. In this way, ACD process 10 (e.g., via the model) may only predict the draft report a sentence at a time based on the scribes typing/feedback. In some implementations, the prediction may be based not just upon what the scribe is currently writing, but may additionally (or alternatively) be based upon the context of what the scribe has previous written in previous sentences of the report (or based upon a training pool specific to the scribe). As discussed above,
As discussed above, automated clinical documentation (ACD) process 10 may be configured to automate the collection and processing of clinical encounter information to generate/store/distribute medical records. Additionally, as discussed above and referring also at least to the example implementation of FIG. 15, ACD process 10 may be configured to obtain 300 encounter information (e.g., machine vision encounter information 102 and/or audio encounter information 106) of a patient encounter (e.g., a visit to a doctor's office) of at least a first encounter participant, wherein the encounter information may include audio encounter information obtained from at least a first encounter participant (e.g., encounter participant 228, 226, 230, and/or 242). ACD process 10 may further be configured to process 302 the encounter information (e.g., machine vision encounter information 102 and/or audio encounter information 106) obtained from at least the first encounter participant, e.g., generate 602 an alert to obtain additional encounter information of the patient encounter, to generate an encounter transcript (e.g., encounter transcript 234) and/or generate 304 a user interface displaying a plurality of layers associated with the audio encounter information obtained from at least the first encounter participant. In some implementations, ACD process 10 may process at least a portion of the encounter transcript (e.g., encounter transcript 234) to populate at least a portion of a medical record (e.g., medical record 236) associated with the patient encounter (e.g., the visit to the doctor's office). Encounter transcript 234 and/or medical record 236 may be reviewed by a medical professional involved with the patient encounter (e.g., a visit to a doctor's office) to determine the accuracy of the same and/or make corrections to the same.
As noted above, ACD process 10 may process 302 the audio encounter information obtained from at least the first encounter participant. In some implementations, processing 302 the first audio encounter information may include defining 306 linkages between each of the plurality of layers associated with the audio encounter information. For example, the first layer of the plurality of layers may be a visualization and/or direct play-back of an audio signal associated with the audio encounter information (e.g., complete audio of the encounter, encompassing and clearly delineating each participant), wherein the second layer of the plurality of layers may be a transcript associated with the audio encounter information (e.g., a diarized audio transcript (verbatim) for each participant in the encounter), and wherein the third layer of the plurality of layers may be a medical report associated with the audio encounter information (e.g., a draft medical report in the appropriate clinical output format). In some implementations, additional layers may include, e.g., the above-noted machine vision-based recording of the encounter, including various signal formats and features, and discrete, standardized, actionable data resulting from the encounter, including, but not limited to medication plans (for example, in RxNorm) or lab orders (for example, LOINC) or diagnoses (for example, ICD10, CPT etc). In the example, the signals captured from the encounter information may be processed 304 into at least the above-noted three separate, yet closely linked and interdependent layers.
In some implementations, ACD process 10 may include an ASR portion that may process 302 the audio encounter information producing an approximate (e.g., diarized) verbatim transcript along with alignment information indicating the audio interval corresponding to each transcript word. In some implementations, a deep learning (e.g., sequence to sequence) model associated with ACD process 10 may convert the transcript to a medical report. It will be appreciated that various attribution techniques may be employed by ACD process 10 that may effectively softly assign responsibility for a given output (e.g., medical report) word to input (e.g., conversation transcript) words (e.g. attention weights, integrated gradient, etc.) according to the model. As a result, this may provide a soft mapping from the transcript word positions to report word positions. In some implementations, the input word position assigned maximal attribution for a given output word may be interpreted as being aligned (linked) to that output (e.g., when a hard mapping is required). Based on the ASR time alignment, a word in the draft medical report, aligned to a word in the ASR conversation transcript, may now be associated with an audio time interval of the associated audio signal of the audio encounter information.
In some implementations, ACD process 10 may also may link (i.e., align) the ASR conversation transcript words with the draft medical report words. For transcript words that may have maximal attribution value for some set of medical report words, ACD process 10 may link them with the first word in that set. For the remaining transcript words, ACD process 10 may link them to the same word that the nearest preceding (or if none, nearest subsequent) conversation transcript word is linked to.
In some implementations, a visual recording (e.g., video stream of the patient encounter), if available, may also be a layer and may be time indexed and thus a given point in the recording may be associated with the same time in the audio recording and thus a conversation transcript word and draft report word. In some implementations, if discrete, standardized, actionable data is produced as a second (parallel) output sequence of the sequence to sequence model, then a similar model output attribution technique may be used to align tokens in this actionable data with the ASR conversation transcript words, and thus the audio intervals.
In some implementations, ACD process 10 may generate 304 a user interface displaying a plurality of layers associated with the audio encounter information obtained from at least the first encounter participant. For example, and referring again at least to the example implementation of FIG. 5, an example user interface (e.g., user interface 500) is shown. It will be appreciated that UI 500 is shown merely for example purposes only, and that more or less features and arrangements of features may be used without departing from the scope of the present disclosure.
As can be seen from FIG. 5, UI 500 includes the first layer of the plurality of layers (e.g., first layer 502 which may be a visualization and/or direct play-back of an audio signal associated with the audio encounter information (e.g., complete audio of the encounter, encompassing and clearly delineating each participant), second layer 504 of the plurality of layers which may be a transcript (e.g., encounter transcript 234) associated with the audio encounter information (e.g., a diarized audio transcript (verbatim) for each participant in the encounter), and third layer 506 of the plurality of layers which may be a medical report (e.g., medical report/record 236) associated with the audio encounter information (e.g., a draft medical report in the appropriate clinical output format). It will be appreciated that that each layer (audio, transcript, draft report, etc.) may be rendered in multiple different ways, and in the most appropriate way for a given use/preference of the end-user. As such, the specific rendering of layers should be taken as example only and not to limit the scope of the disclosure.
As noted above, encounter transcript 234 (via second layer 504) and/or medical record/record 236 (via third layer 506) may be reviewed by a medical professional involved with the patient encounter (e.g., a visit to a doctor's office) to determine the accuracy of the same and/or make corrections to the same. For example, a scribe involved with (or assigned to) the patient encounter (e.g., a visit to a doctor's office) may review encounter transcript 234 and/or medical record 236 to confirm that the same was accurate and/or make corrections to the same. In the event that corrections are made to encounter transcript 234 and/or medical record 236, automated clinical documentation process 10 may utilize these corrections for training/tuning purposes (e.g., to adjust the various profiles associated the participants of the patient encounter) to enhance the future accuracy/efficiency/performance of automated clinical documentation process 10.
Alternatively/additionally, a doctor involved with the patient encounter (e.g., a visit to a doctor's office) may review encounter transcript 234 and/or medical record 236 to confirm that the same was accurate and/or make corrections to the same. In the event that corrections are made to encounter transcript 234 and/or medical record 236, automated clinical documentation process 10 may utilize these corrections for training/tuning purposes (e.g., to adjust the various profiles associated the participants of the patient encounter) to enhance the future accuracy/efficiency/performance of automated clinical documentation process 10.
As such, and referring again at least to the example implementation of FIG. 6, assume for example purposes only that a scribe is reviewing the encounter information using UI 500. In some implementations, ACD process 10 may receive a selection of a first portion of the audio encounter information at a first layer of the plurality of layers on the user interface, and ACD process 10 may display an annotation of at least one of a second layer of the plurality of layers and a third layer of the plurality of layers corresponding to the first portion of the audio encounter information of the first layer of the plurality of layers selected on the user interface. For instance, the scribe may use, e.g., cursor 508 or other known input techniques, to select a portion of first layer 502 (i.e., the audio information of the audio encounter information), which may be received by ACD process 10. As a result, in some implementations, ACD process 10 may display some kind of annotation of either the second layer (e.g., the portion of the transcript associated with the selected portion of the first layer) and/or the third layer (e.g., the portion of the medical report associated with the selected portion of the first layer). In the example, ACD process 10 has displayed an annotation (e.g., bold font) of the second layer (e.g., the portion of the transcript associated with the selected portion of the first layer) and the third layer (e.g., the portion of the medical report associated with the selected portion of the first layer). It will be appreciated that any type of annotation may be used (e.g., bold, italics, underline, highlights, shading, transparency, etc.) without departing from the scope of the present disclosure. As such, the use of bolding as the annotation should be taken as example only and not to otherwise limit the scope of the disclosure.
Similarly, in some implantations, ACD process 10 may receive a selection of the first portion of the audio encounter information at one of the second layer of the plurality of layers and the third layer of the plurality of layers on the user interface, and ACD process 10 may provide audio of the first layer corresponding to the first portion of the audio encounter information of one of the second layer of the plurality of layers and the third layer of the plurality of layers selected on the user interface. For example, and referring to the example implementation of FIG. 7, the scribe may use, e.g., cursor 508 or other known input techniques, to select a portion of second layer 504 (e.g., the transcript), and/or the third layer (e.g., the medical report) which may be received by ACD process 10. As a result, in some implementations, ACD process 10 may provide the audio of first layer 502 (e.g., the audio information of the audio encounter associated with the selected portion of second layer 504).
As such, ACD process 10 may leverage the above-noted defined linkages, such that the encounter recording as captured above may be provided to a human scribe (or physician) in such a fashion, so that they may navigate through each of these layers independently and be always in sync. For instance, if the scribe navigates through first layer 502 (audio) by listening, the part of the transcript that corresponds to that part of the audio may be bolded, highlighted, etc. accordingly, as well as the resulting medical report (and if relevant actionable data) from that information. Additionally/alternatively, if the scribe selects a part of the report, the audio/transcript sections that affected that part of the report may be bolded, highlighted, emphasized, etc. This annotation also may correspond to the audio and report “cursor” (e.g., audio cursor 510) moving, e.g., audio may next play from that position and typing/keyboard-navigation may commence from that position in the report. As a result, since each of the plurality of layers may be synchronized, a scribe (or physician, etc.) may later playback the whole patient encounter, navigate (e.g., “clicking” a mouse cursor of other pointing device at any position) in any portion of any of the layers, make edits, and would know which edit/correction belongs to the other sections (layers). More generally, “clicking” (i.e. resetting the cursor) in one viewed layer may annotate and update the cursor in the linked points/excerpts in the other layers.
As noted above, ACD process 10 may generate 602 an alert (e.g., an audio alert or a visual alert such as a pop-up message, text message, email, etc.) to obtain additional encounter information of the patient encounter. For example, ACD process 10 may be aware of the relevant sections of the above-noted medical report sections when processing the obtained encounter information, as well as explicit data points (such as physical exam findings, lab orders, etc.). In the example, as will be discussed below, ACD process 10 may determine that, e.g., additional information may be needed from the patient, since some of the current encounter information obtained so far may be vague, missing, could not be documented/verified (e.g., neurological section, extremities, etc.), or information which would make the patient encounter more compliant to clinical/administrative guidelines. In some implementations, such as the above example, ACD process 10 may generate 602 an alert (e.g., for the physician) to obtain additional encounter information of the patient encounter to address the encounter information deficiencies.
In some implementations, the alert may be generated 602 and provided to the physician (or other healthcare professional) while the patient is still in the examination room to make it easier to then obtain the additional encounter information; however, the alert may be generated at any time. In some implementations, a virtual assistant (e.g., virtual assistant 238 from FIG. 2) may generate and provide the alert to inform any medical professional (e.g., doctors, nurses, physician's assistants, lab technicians, physical therapists, scribes/transcriptionist, etc.) and/or staff members involved in the patient encounter) to gather the additional encounter information. In some implementations, the alert may be provided during a pre-visit portion of the patient encounter (e.g., patient check in) and/or a post-visit portion of the patient encounter (e.g., check out).
In some implementations, processing 302 the first audio encounter information may include comparing 606 at least one layer of the plurality of layers with at least one data source, which may include at least one of physical exam finding information, lab order information, medical condition checklist information, and compliance information. For example, as discussed above with regard to at least FIG. 2, ACD process 10 may be configured to access one or more data sources 118 (e.g., plurality of individual data sources 120, 122, 124, 126, 128), examples of which may include but are not limited to one or more a medical conditions symptoms data source, a prescriptions compatibility data source, a medical insurance coverage data source, a data source storing past/present physical exam findings of the patient, past/present lab order information for the patient, a medical compliance data source, combination thereof, etc.
Continuing with the above example, assume for example purposes only that the information documented in the medical report section of UI 500 denotes that the physician has conducted a standard physical examination for the patient. In the example, assume that the standard physical examination has nine medical points that should be checked for a standard physical examination (e.g., eyes, throat, reflexes, blood pressure, etc.). Further assume in the example that only eight of the nine medical points that should be checked for a standard physical examination have been completed by the physician. In the example, ACD process 10 may use the patient encounter information (e.g., from the medical report) to determine that a standard physical examination has been conducted with only eight medical points being documented, obtain one of the above-noted data sources that indicates that there are nine medical points that should be checked for a standard physical examination, compare 606 the information in the medical report (e.g., the eight documented medical issues) with one of the obtained data sources that indicates that there are nine medical points that should be checked for a standard physical examination, determine that one of the medical points that should be checked for a standard physical examination has not been documented in the medical report (e.g., blood pressure), and generate an alert for the physician to obtain the missing ninth medical point (e.g., blood pressure). In some implementation, the encounter information in the medical report section that was used (at least in part) to determine that an alert should be generated may be annotated (as discussed above) to help the physician confirm that additional information is indeed needed.
As another example, assume that for example purposes only that the information documented in the medical report section of UI 500 denotes that the physician has conducted a standard physical examination for the patient. In the example, assume that the standard physical examination includes a mandatory blood test. Further assume in the example that the physician has not ordered a blood test. In the example, ACD process 10 may use the patient encounter information (e.g., from the medical report) to determine that a standard physical examination has been conducted without a blood test being documented, obtain one of the above-noted data sources that indicates that a blood test should be included for a standard physical examination, compare 606 the information in the medical report (e.g., showing a lack of blood being drawn or blood test being ordered) with one of the obtained data sources that indicates that a blood test should be included for a standard physical examination, determine that the patient's blood should be drawn and a blood test should be ordered for a standard physical examination that has not been documented in the medical report (e.g., blood pressure), and generate an alert for the physician to obtain the missing information (e.g., blood draw/test).
It will be appreciated that while the above example involves an indication of missing information from a medical examination, other examples of missing (or vague) information may be used without departing from the scope of the present disclosure. For instance, ACD process may similarly generate an alert if the information in the medical report indicates additional information may need to be obtained from the patient encounter to be more compliant with clinical/administrative guidelines. As another example, ACD process may similarly generate an alert if the information in the medical report indicates a particular prescription has not been filled/refilled where one of the above-noted data sources indicates that the particular prescription should be filled/refilled. As another example, ACD process may similarly generate an alert if the information in the medical report indicates symptoms of a particular illness that could be verified by examining some part of the patient that has been examined. As such, the specific disclosure of generating an alert for a missed medical examination point should be taken as example only and not to otherwise limit the scope of the present disclosure.
