Description

  Embodiments described herein relate generally to a medical information management apparatus.

  In recent years, with the spread of multi-slice CT (computed tomography) and MRI (magnetic resonance imaging), the number of examinations read by doctors is increasing. For this reason, techniques for efficiently performing interpretation work such as use of past reports, association with findings, switching of conversion candidate prediction, detection of lesions, and presentation of related examinations have been developed. Similarly, presentation of medical status is a technique for efficiently performing interpretation work. Since the medical status is not included in examination information such as examination order, medical image information, medical report, etc., it is manually extracted by the user in the selection format or extracted by pattern matching from the character string contained in the examination information. There is a need.

Hereinafter, an operation example of the medical information system related to the medical status determination process by the medical information management apparatus 1 will be described. The medical status determination processing according to the present embodiment is roughly divided into two types: a type for determining a lesion determination parameter using an examination order and a type for determining a lesion determination parameter using a medical record. Hereinafter, a type using an examination order will be described in the first embodiment, and a type using a medical record will be described in a second embodiment.
Example 1
FIG. 7 is a diagram illustrating an operation flow of each device of the medical information system 100 related to the medical status determination process according to the first embodiment. As shown in FIG. 7, order information for the examination order of the current examination and the name of the lesion to be examined in the current examination are input by the attending physician or the like via the input device of the RIS examination order issuing apparatus 200 (step SA1). The order information is information necessary for issuing an inspection order for the current inspection. The lesion name is the name of the lesion to be examined in this examination. One or more lesion names may be input. The lesion name may be extracted from the order information by pattern matching. The lesion name to be input may be input by distinguishing the main lesion from the metastatic lesion, or may be input as one lesion. For example, in the case of lung cancer, the main lesion of lung cancer, the brain metastasis of lung cancer, and the lymph node metastasis of lung cancer may be input separately, or may be input collectively as lung cancer.

  When step SA1 is performed, the RIS inspection order issuing apparatus 200 issues the inspection order for the current inspection based on the input order information (step SA2). The issued examination order is transmitted to the medical image photographing apparatus 600. The medical imaging apparatus 600 receives the examination order from the RIS examination order issuing apparatus 200, performs medical imaging according to the received examination order, and generates a medical image related to the patient (step SA3). The generated medical image is transmitted from the medical image photographing apparatus 600 to the medical image storage apparatus 500 of the PACS. The PACS medical image storage device 500 receives a medical image from the medical image photographing device 600 and stores the received medical image. The medical image is used for subsequent interpretation.

  When step SA2 is performed, the RIS examination order issuing device 200 transmits the examination order and the lesion name related to the current examination to the medical information management device 1. The medical information management apparatus 1 receives the examination order and the lesion name regarding the current examination from the RIS.

  Next, the read / write unit 21 of the medical information management device 1 reads treatment event information related to the current examination from the treatment event storage unit 13 (step SA4). As shown in FIG. 3, the treatment event information includes a patient ID, a treatment date and time, and a treatment lesion name. The read / write unit 21 searches the treatment event storage unit 13 based on the patient ID and the lesion name included in the order information input in step SA1, and uses the treatment event information associated with the lesion input in step SA1 as a treatment event. Read from the storage unit 13. Note that the method for reading treatment event information is not limited to the above method. For example, in order to read treatment event information related to the current examination, the user inputs at least one piece of information on the patient ID, treatment date and time, and treatment lesion name related to the current examination via the operation unit 33, and the read / write unit 21 is input. The treatment event storage unit 13 is searched using the obtained information as a keyword, and the treatment event information associated with the input information is read from the treatment event storage unit 13.

  The following processing from step SA5 to step SA11 is repeated for each lesion name. For example, when lung cancer and pneumonia are read as lesion names, the processes from step SA5 to step SA11 are performed for each of the lung cancer and pneumonia. When distinguishing the main lesion from the metastatic lesion, the processes from Step SA5 to Step SA11 are performed for each of the main lesion and the metastatic lesion. For example, the main lesion of lung cancer may be distinguished from brain metastases and lymph node metastases.

  The end stage of step SA4 is a stage where an examination order for the current examination is issued and medical imaging is performed. At this stage, in general, lesion information for this examination is not created. That is, the lesion information on the target lesion stored in the lesion information storage unit 19 at the end stage of step SA4 is the lesion information of the previous examination on the target lesion.

  When step SA4 is performed, the read / write unit 21 reads the lesion information of the previous examination for the target lesion from the lesion information storage unit 19 based on the patient ID and the lesion name included in the order information (step SA5). As shown in FIG. 6, the lesion information includes a patient ID, an order ID, a lesion name, a lesion determination parameter, a medical status, an examination date and time, and a previous examination date and time. In order to read the lesion information of the previous examination for the target lesion, the user searches the lesion information storage unit 19 using the combination of the patient ID and the lesion name input in step SA1 as a keyword, and determines the patient ID and the lesion name. The lesion information associated with the combination is read from the lesion information storage unit 19. This read lesion information is the lesion information of the previous examination.

  When step SA5 is performed, the lesion information creation unit 25 of the medical information management apparatus provisionally creates the lesion information of the current examination using the lesion information of the previous examination read in step SA5 (step SA6). For example, the value of the lesion confirmation parameter is set to the value of the lesion confirmation parameter of the previous examination read in step SA5, the value of the medical status is set to the value of the medical status of the previous examination read in step SA5, The value of the previous inspection date / time is set to the value of the inspection date / time read in step SA5. Further, the order ID and the inspection date and time values are set to the inspection date and time of the current inspection. The lesion information creation unit 25 may set a value input by the user via the operation unit 33 as the value of the examination date and time of the current examination, or may automatically set the value.

  In step SA5, the lesion information of the previous examination may not be stored in the lesion information storage unit 19. For example, when the current examination is the first examination, there is no lesion information of the previous examination in the lesion information storage unit 19. In this case, the lesion information creation unit 25 provisionally creates the lesion information of the current examination using predetermined lesion information determined in advance (step SA7). The predetermined lesion information can be arbitrarily set in advance by the user via the operation unit 33 or the like for each lesion information item. Hereinafter, the value of each item of the lesion information set in advance is referred to as a preset value. For example, “no doubt” is set as the preset value of the lesion determination parameter, “screening” is set as the preset value of the medical status, “N / A” is set as the preset value of the previous examination date, and the examination date preset The date and time of the current examination is set as a value. In this case, the lesion information creation unit 25 sets the value of the lesion determination parameter to “no doubt”, sets the value of the medical status to “screening”, and sets the value of the previous examination date to “N / A”. The inspection date and time are set to the current inspection date and time. The lesion information creation unit 25 may set a value input by the user via the operation unit 33 as the value of the examination date and time of the current examination, or may automatically set the value. Thereby, the lesion information of this examination is created provisionally.

  When step SA6 or SA7 is performed, the lesion determination parameter specifying unit 27 specifies the lesion determination parameter of the current examination using a specific character string included in the examination order transmitted from the RIS (step SA8). Specifically, first, the lesion determination parameter specifying unit 27 reads a lesion determination parameter database stored in the lesion determination parameter storage unit 15. The lesion determination parameter specifying unit 27 specifies the search character string defined in the lesion parameter database from the character strings described in the examination order transmitted from the RIS.

  More specifically, first, the lesion determination parameter specifying unit 27 specifies a search destination related to the examination order from search destinations defined in the lesion parameter database. For example, in the case of FIG. 4, the inspection purpose included in the record of rule ID1 and the record of rule ID2 corresponds to the search destination related to the inspection order. Next, the lesion determination parameter specifying unit 27 specifies a search character string associated with a search destination related to the examination order. For example, in the case of FIG. 4, a search character string in which “preoperative examination” of the record with the record ID 1 and ““ lesion name ”+“ suspect ”” of the record with the record ID 2 are associated with the search destination regarding the examination order. It corresponds to. Next, the lesion determination parameter specifying unit 27 specifies the specified search character string from the character strings included in the examination order. For example, when the search character string is “preoperative examination”, the character string “preoperative examination” is specified from the character strings included in the examination order. When the search character string is ““ lesion name ”+“ no doubt ””, the character string ““ lesion name ”“ no doubt ”” is specified from the character strings included in the examination order. As the “lesion name”, a lesion name transmitted from the RIS or a lesion name included in a treatment event is used. The lesion determination parameter specifying unit 27 replaces the lesion name transmitted from the RIS and the lesion name included in the treatment event with the “lesion name” of the search character string, and ““ The character string “suspicious name” is specified. For example, when the “lesion name” is “lung cancer”, the character string “suspected lung cancer” is specified from the examination order. Alternatively, a lesion name variation dictionary may be prepared in advance, and the lesion name variation example may be replaced with a “lesion name” to specify a character string from among the character strings included in the examination order. For example, for “liver cancer”, a dictionary of modified examples such as “liver cancer”, “liver cancer”, “liver cancer” and “liver cancer” is prepared, and from among the character strings included in the examination order “Suspected liver cancer”, “suspected liver cancer”, “suspected liver cancer”, “suspected liver cancer”, and “suspected liver cancer” may be specified. When the search character string is specified from the examination order, the lesion confirmation parameter associated with the search character string in the lesion confirmation parameter database is set as the lesion confirmation parameter of the current examination. For example, in FIG. 4, when the character string “preoperative examination” is specified from the examination order, the lesion confirmation parameter for the current examination is set to “confirmed”. Further, in FIG. 4, when the character string “suspected lung cancer” is identified from the examination order, the lesion determination parameter of the current examination is set to “suspected”.

  When step SA8 is performed, the medical status determination unit 29 applies the lesion determination parameter specified in step SA7 and the lesion name of the current examination to the status transition information regarding the lesion name of the current examination, and determines the medical status of the current examination. Determine (step SA9). As described above, the status transition information storage unit 17 stores status transition information in association with each of a plurality of disease names. The status transition information is information indicating the transition of the medical status according to the lesion determination parameter. For example, the status transition information is a file expressing the transition of the medical status according to the lesion determination parameter. The status transition information may be expressed in a database format, or may be expressed in a description language such as XML or HTML.

  FIG. 8 is a diagram schematically illustrating status transition information in a flowchart format. The status transition information in FIG. 8 shows the status transition information of solid cancer as an example. The status transition information is created based on a general diagnosis flow of solid cancer. Screening is the clinical status of a test that searches for lesions. When a lesion is added during the examination, screening is set as the medical status of the examination. As a result of the screening, if it is determined that there is no suspicion of the solid cancer before the test, the diagnosis for the solid cancer is completed. On the other hand, when it is determined that there is a suspicion of solid cancer, the medical status shifts to the close examination A. The close examination A is a medical status of examination for differential diagnosis before treatment. When it is determined that there is no suspicion of a lesion as a result of interpretation in the close examination A, the diagnosis for solid cancer is completed. On the other hand, when it is determined that the presence of the solid cancer is confirmed as a result of the interpretation in the detailed examination A, the medical status shifts to the follow-up observation A. The follow-up A is a medical status of an examination for observing a lesion before treatment. As a result of the follow-up observation A, when it is determined that there is a suspicion of metastasis, the medical status shifts to the close examination A again. As a result of the follow-up A, when a treatment event occurs (that is, when a solid cancer is treated after a follow-up of a lesion whose presence has been confirmed by a close examination), the medical status shifts to the follow-up B. The follow-up B is a medical status of an examination for observing a lesion after treatment. As a result of interpretation in the follow-up B, if it is determined that there is a suspicion of recurrence or metastasis, the medical status shifts to the close examination B. The close examination B is a medical status of examination for differential diagnosis of recurrence and metastasis after treatment. If the presence of recurrence or metastasis is confirmed as a result of interpretation in the close examination B, the diagnosis status shifts to follow-up observation A. On the other hand, if it is determined as a result of the close inspection B that there is no suspicion of recurrence or metastasis, the diagnostic status shifts to follow-up B. If it is determined as a result of follow-up B that the patient has been completely cured, the diagnosis of solid cancer is completed.

  “No doubt”, “suspected”, and “confirmed” in FIG. 8 are used as lesion confirmation parameters in this embodiment. The present inventors have found that the medical status of the current examination can be determined if the lesion determination parameter and the medical status of the previous examination are known.

  The medical status determination unit 29 according to the present embodiment determines the medical status of the current examination from the status transition information using the lesion determination parameter and the medical status of the previous examination.
