Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This Application claims the benefit of priority from Provisional Application No. 61/839,528, entitled “Systems and Methods for Managing Patient Conditions,” filed Jun. 26, 2013, which is incorporated herein by reference in its entirety.

TECHNICAL HELD

Various embodiments of the present disclosure relate generally to managing medical adherence. More specifically, particular embodiments of the present disclosure relate to systems and methods for managing medical adherence utilizing data aggregation and processing the data to determine impact on a patient's health based on their behavior related to a prescribed medication.

BACKGROUND

An important aspect of medical care is medication management. In fact, medication adherence, that is, a patient's utilization of the prescribed regimen of medication on time and in the correct dosage, is directly related to the success of the treatment or management of a medical condition. For example, organ transplant patients may be prescribed pills in the order of 30-50 per day that have to be consumed at specific times through the day. Inconsistency in adherence to the prescribed regimen may have serious short-term and long-term consequences, such as organ rejection or even death. Mismanagement of regimens associated with other medical conditions, such as HIV, allergies, diabetes, asthma, hypertension, may also lead to similar consequences that range from causing discomfort to being lethal.
Typically, various health service provides, provide “pill-box” type resources to monitor medication adherence. These resources are limited to providing users with reminders of the medicine they have taken or simply keeping a record of actions related to compliance with a medication regimen.
However, it can be difficult for a healthcare provider to efficiently manage a patient's medical adherence utilizing such an approach to improve a patient's health or clinical outcomes.

Reference will now be made in detail to the exemplary embodiments of the disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
FIG. 1 is a schematic diagram of an exemplary network environment in which various systems may manage and monitor medical adherence, according to an embodiment of the present disclosure. As shown in FIG. 1, the environment may include a plurality of user or client devices 102 that are communicatively coupled to each other as well as one or more server systems 106 via an electronic network 100. Electronic network 100 may include one or a combination of wired and/or wireless electronic networks. Network 100 may also include a local area network, a medium area network, or a wide area network, such as the Internet.
In one embodiment, each of user or client devices 102 may be any type of computing device configured to send and receive different types of content and data to and from various computing devices via network 100. Examples of such a computing device include, but are not limited to, mobile health devices, a desktop computer or workstation, a laptop computer, a mobile handset, a personal digital assistant (PDA), a cellular telephone, a network appliance, a camera, a smart phone, an enhanced general packet radio service (EGPRS) mobile phone, a media player, a navigation device, a game console, a set-top box, a biometric sensing device with communication capabilities, or any combination of these or other types of computing devices having at least one processor, a local memory, a display (e.g., a monitor or touchscreen display), one or more user input devices, and a network communication interface. The user input device(s) may include any type or combination of input/output devices, such as a keyboard, touchpad, mouse, touchscreen, camera, and/or microphone.
In one embodiment, each of the user or client devices 102 may be configured to execute a web browser, mobile browser, or additional software applications that allows for input from patients and other individuals from the medical field including physicians, nurses, pharmacists, etc. One or more of user or client devices 102 may be further configured to execute software allowing for monitoring of patient behavior including the ability to receive user input or utilizing associated sensors to monitor patient behavior. For example, user or client devices 102 may contain an application which allows it to receive data from a paired and/or integrated blood sugar level monitor and then transmit the data to other entities within environment 100. Alternatively, user or client devices 102 may contain applications which allow for a patient to input information related to patient behavior such as consumption of medication, including, but not limited to, dosage and/or compliance information.
Server system 106 in turn may be configured to receive data related to a medication regimen, individual medications in a medication regimen, patient, patient behavior, etc. It should be noted that while a singular server system 106 is described, method 200, described below with respect to FIG. 2, may be implemented using a plurality of server systems working in combination, a single server device, or a single system.
Also, as shown in FIG. 1, server system 106 may include one or more databases 108. In an embodiment, databases 108 may be any type of data store or recording medium that may be used to store any type of data. For example, databases 108 may store data received by or processed by server system 106 including information related to a patient's prescribed regimen, including timings and dosages associated with each medication of the regimen. Databases 108 also may store information related to the patient including their literacy level related to each of the prescribed medications.
Additionally, as shown in the example of FIG. 1, server system 106 may include processor 110. In an embodiment, processor 110 may be configured to execute a process for managing medical adherence. The management process may, for example, continue to constantly monitor regular (e.g., daily, weekly, monthly, etc.) compliance to time and dosage of a medical regimen. Utilizing these values along with additional factors, metrics may be generated which efficiently indicate a patient's overall adherence to a medication regimen.
In an embodiment, processor 110 may be configured to receive instructions and data from various sources including user or client devices 102 and store the received data within databases 108. In some implementations, any received data may be stored in the databases 108 in an encrypted form to increase security of the data against unauthorized access and complying with HIPAA privacy regulations. Processor 110 or any additional processors within server system 106 also may be configured to provide content to client or user devices 102 for display. For example, processor 110 may transmit displayable content including messages or graphic user interfaces soliciting information related to patient behavior.
FIG. 2 is a flow diagram of a method 200 for managing a patient's medical adherence, according to an embodiment of the present disclosure.
In step 202, method 200 includes receiving data related to the patient. For example, this data may be received and/or retrieved by processor 110 from one or more databases 108 or may be directly received from one or more user or client devices 102. The data may include information related to a medication regimen associated with the patient that includes one or more medications, patient behavior data (e.g. objective and subjective data), a respective literacy level associated with each of the one or more medications, and a respective drug importance factor associated with each of the one or more medications. This received data may previously be generated utilizing processor 110 and stored in databases 108. Alternatively, the received data may be transmitted by one of user or client devices 102, including data previously transmitted and stored in databases 108. In embodiments, one of user or client devise 102 may transmit data in real time, continuously, periodically, or based on a predetermined duty cycle.
In embodiments, information related to a medication regimen, may include information regarding all the medicine included in the regimen including prescribed dosage and times related to the medication.
In additional embodiments, this information may include unique identities assigned to the regimen and unique identities assigned to each of the one or more medications in the regimen allowing for easier management of data. For example, in the case of multiple diseases for which a patient may be treated, regimen identities may be assigned by multiples of 100. For example, a first disease regimen number may be 100, a second disease regimen number may be 200, and henceforth. As discussed earlier, each regimen may contain one or more medications prescribed by a physician. Each medication in a regimen may be assigned a unique number for identification. For example, D[i,j], D[i,j+1] . . . D[i, n#i], where Medication ID=subscript 1, subscript 2. Here, Here subscript 1 (e.g., i) refers to the regimen number and subscript 2 (e.g., j, j+1, . . . ) refers to the ID of the medication in the same regimen. The regimen numbers may be assigned in incremental manner sequentially starting from first regimen of the patient.
Accordingly, while data related to a medical regimen may be captured based on the original medication name, the data may be managed in an easier manner by assigning each medication a unique identity utilizing the naming convention discussed above. In some embodiments, other suitable name/identifying conventions may be used with the principle of this disclosure.
For example, FIGS. 3A and 3B illustrate an exemplary implementation of calculating the regimen number and assigning unique identification numbers, according to an embodiment of the present disclosure. Step 308 entails assigning each respective disease a unique disease number, disease 310 (HIV) is assigned a “1,” disease 311 (diabetes) is assigned a “2,” and disease 312 (cancer) is assigned a “3.” Thereafter, in step 304, each of the assigned numerical values are multiplied by 100 to produce disease regimen numbers 314, 316, and 317 for the respective diseases. The disease numbers from step 304 are then utilized to calculate medication number in step 306. Step 306 is illustrated in more detail in FIG. 3B. Using the disease regimen numbers 314, 316, and 317, the mediation numbers are calculated by incrementally adding an incremental integer value to the disease number starting with 1 for each respective medication associated with the regimen. For example, for disease 310 (HIV), for a first medication 320 (Comibir) associated with disease regimen number 314, a 1 is added to 100 to calculate a medication number value of 101. For a second medication 321 associated with disease regimen number 314, a 2 is added to 100 to calculate a medication number value of 101. The medication numbers for medications 322, 323, 324, and 325 are similarly calculated based on the associations of these medications with respective disease regimens 316 and 317. In some embodiments, these values then may be stored in databases 108.
In embodiments, patient behavior data may refer to data related to patient behavior including when and if a patient complied with recommendations of a regimen For example, patient behavior data may indicate that a patient orally consumed a certain dosage of medication at various specific times such as 8 a.m., 2 p.m., and 8 p.m. daily.
In embodiments, literacy level (LL) is a metric to assess the familiarity of a patient with a prescribed regimen and its medications. This value may be calculated or updated based on various conditions. In a first exemplary condition, a patient may be asked to take a survey with questions related to literacy regarding medical adherence for the unique regimen. This survey or observations by a physician regarding a patient's knowledge base may be utilized to set the baseline literacy level for a patients particular regimen. The score based on a survey or a physician's observations may be updated subsequently based on additional surveys or observations. In a second exemplary condition, the literacy level may be impacted by determination that erroneous medication data was entered by a patient using user or client device 102 a threshold amount of times over a particular period. For example, in monitoring daily medication adherence over a week, it may be determined that the patient entered erroneous medication data or did not enter any medication data a threshold amount of times in the week. Thereafter, the assigned literacy level to the regimen may be dropped. In a third exemplary condition, the literacy level may be impacted based on occurrence of a condition based on lack of medical adherence by a patient. For example, if there are any ill effects based on user behavior, such as lowering of blood sugar levels due to missing medication.
In embodiments, intervention techniques, such as changing the types of medicine or motivational interviews with patients, may be applied in response to determination of low literacy levels. Motivational interviews may include a physician (or other medical professional) speaking with a patient, discussing benefits of following the regimen, and explaining impact of failure to do so. Thereafter, levels of error, ill effects, and survey results may be reassessed alter a certain time period, suds as daily, weekly, monthly basis.
In embodiments, drug importance factor (DIF) may be entered by a medical professional (e.g., physician, pharmacist, physician's assistant, etc.) associated with a patient's medical regimen utilizing a user or client device 102. This value may allow for defining a relative importance of a given medication with respect to other medications in the same regimen for a specific patient or disease being treated. In detail, data related to the assignment of drug importance factors may be assigned by a physician during medication validation. While a physician may utilize a comparison or relativity in their thought process for assigning the drug importance factor, each medication in a regimen is assigned a drug importance factor without any contingency on any other medication. As an example, a physician may be provided with a data entry field next to each medication to weigh its importance for the prescribed regimen, on a scale of 1 to 3. In such an example, it is possible for all medications in a regimen to get an assigned value of 3 each if found important. Alternatively, any suitable scale may be used which is consistence with the principle of the present disclosure. However, in embodiments, a minimum of 1 is assigned in order to ensure all medications obtain a non-zero value for the purposes of being able to calculate a daily medication adherence as is discussed in further details below.
In an additional embodiment, for calculating the drug importance factor (DIF), the rationale behind a physician's drug importance factor scoring may be partially supplemented by using pharmacokinetic techniques. The drug importance factor baseline may be based on clinical data or set by a certified pharmacologist by examining interrelationships between medications and hence their effects on similar patients.
In step 204, method 200 includes calculating a compliance to dosage and a compliance to time for each of the one or more medications based on the received data.
Regarding compliance to dosage, this value may be calculated utilizing exemplary method 400. In step 402, step 400 includes determining prescribed dosage for each of the one or more medications based on the received data That is, the presence disclosure contemplates utilizing information regarding the prescribed regimen to determine dosage associated with each of the one or more medications. For example, this may be based on the prescription information input by a physician or a physician's assistant in-charge of providing medical services to a patient.
In step 404, method 400 includes assigning boolean (or binary) values for actual dosage consumed based on the prescribed dosage and received data related to patient behavior. For example, data associated with patient behavior may indicate whether a patient consumed a particular prescribed dosage. Accordingly, in an exemplary embodiment, when a dosage is consumed, a value of “1” may be assigned, while when a dosage is not consumed a value of “0” might be assigned. Since, a patient may consume an inaccurate amount of the prescribed dosage, different thresholds may be assigned regarding whether a partial consumption leads to an assignment of “1” or “0” value. For example, if a dosage of three pills of a first medication is assigned and the patient consumes only two out of the three pills, a boolean may be assigned a “1” if a threshold value is preset so that anything higher than a 60% consumption of a dosage is considered to be compliant. This threshold amount may be preset by a medical professional taking into account in the importance of the medicine, impact on variations in dosage, and other additional factors.
In step 406, method 400 includes calculating compliance to dosage for each of the one or more medications utilizing the assigned boolean values. For example, for ten dosages prescribed throughout the day, the boolean values may be utilized to calculate an overall value for the day. For example, if 8 out of 10 prescribed dosages for a particular medication where complied with throughout the day, then the actual consumed dosage would be assigned a “1” for those 8 instances and a “0” would be assigned for the other two instances. Accordingly, a compliance value of 0.8 may be calculated for the compliance to dosage for that particular medicine by dividing the overall boolean value with the total prescribed instances.
In additional embodiments, the compliance to dosage may simply be a ratio of dosage consumed to total dosage prescribed. For example, if a patient was prescribed 10 units of a medication in a day and took only 8 units, then the respective compliance to disease is obtained by dividing the amount of units actually consumed by the prescribed units. In this instance, it would be 8/10 which equals 0.8.
Compliance to dosage may provide valuable information about a patient's behavior. For example, an indication regarding a trend in a rise or drop of medication taken may be very significant for certain patients, such as patients on a short acting insulin regimen to control their diabetes.
Regarding compliance to time, this interaction may be calculated utilizing exemplary method 500. In step 502, method 500 includes determining prescribed dosage time for each of the one or more medications based on the received data. That is, utilize information regarding the prescribed regimen to determine the time when each of the one or more medications is to be consumed. For example, this may be the prescription information input by a physician or a physician's assistant in-charge of providing medical services to a patient.
In step 504, method 500 includes assigning boolean (or binary) values for actual consumption time based on the prescribed dosage time and received data related to patient behavior. For example, data associated with patient behavior may indicate the time a patient consumed a particular dosage. Accordingly, in an exemplary embodiment, when a dosage is consumed at the correct time, a value of “1” may be assigned, while when a dosage is not consumed at a prescribed time, a value of “0” might be assigned. Since, a patient may not always consume the medicine at the prescribed time, a threshold amount of time may be set which is considered as still complying with the regimen. For example, if a threshold of 15 minutes is set, then if the patient consumes a dosage fifteen minutes before or after a prescribed time of 6 p.m., the consumed dosage may be considered to be complying with the prescribed dosage time. The threshold amount of time may be preset by a medical professional taking into account in the importance of the medicine, impact on variations in dosage, and other additional factors including, but not limited to availability of the prescribed medication.
In step 506, method 500 includes calculating compliance to time for each of the one or more medications utilizing the assigned boolean values. For example, for ten dosages prescribed throughout the day, the boolean values may be utilized to calculate an overall value for the day. For example, if 8 out of 10 actual consumption times for a particular medication complied with the prescribed dosage times, then the actual consumption time would be assigned a “1” for those 8 instances and a “0” would be assigned for the other two instances. Accordingly, a compliance value of 0.8 may be calculated for the compliance to time for that particular medicine by dividing the overall boolean value with the total instances.
In additional embodiments, the compliance to time may simply be a function of the time delays associated with consumed dosages. For example, the prescribed times for dosages may be utilized as a baseline, and every instance of non-compliance of time related to a dosage may result in a drop in the compliance to time value. In embodiments, the drops in a compliance to time value may be proportional to the time delays and/or early consumption.
In some embodiment, the compliance to time may be a function of times and dosage. For example, consumption of a prescribed amount of medication at the suggested time would count as 100 percent compliance for that instance. However, a five minute delay may count as 75% compliance, a ten minute delay may count as 50% compliance, and so on and so forth, until a time when the prescribed dose is considered to have zero percent compliance. The times for the percent of compliance may be set based on pharmaceutical and clinical research associated with the effectiveness of a medication, and other factors. For example, if insulin is to be injected by a diabetes patient at 2 p.m. with an expectation of a meal to be consumed at 2:30 p.m., then injecting it at 2:30 p.m. may not have the desired impact that injecting it on schedule would have.
With reference to FIG. 2, in step 206, method 200 further includes calculating a drug adherence count (DAC) associated with each of the one or more medications. In detail, the drug adherence count may be calculated by summing at least two of the compliance to dosage (CD), the compliance to time (CT), and the respective literacy level (LL) associated with each of the one or more medications. In embodiments, the drug adherence count may be calculated by summing all three of the compliance to dosage (CD), the compliance to time (CT), and the respective literacy level (LL) associated with each of the one or more medications.
In embodiments, drug adherence count (DAC) serves as a metric that efficiently accounts for a consumed medication including compliance with respective prescribed time of the day when it is supposed to be taken, compliance with respective prescribed dosage of the medication, and a patient's literacy about the medications the regimen. In an exemplary embodiment, the calculation of DAC may be presented in an equation as follows:
DAC=CD+CT+LL
In step 208, method 200 includes determining a daily medication adherence (DDA) for each of the one or more medications based on the drug adherence count (DAC) and the drug importance factor (DIF) associated with each of the one or more medications. In embodiments, the daily medication adherence is determined by multiplying the drug adherence count by the drug importance factor associated with each of the one or more medications. In embodiments, daily medication adherence is a metric which aids in efficiently indicating adherence towards the proscribed regimen by adding relative weightage to medication that is considered more relevant or important. Continuing the example from step 206, the calculation for determining the DDA may be presented in an equation, as follows:
DDA=DAC×DIF
In step 210, method 200 includes calculating a daily regimen adherence (DRA) value by summing the daily medication adherence of all of the one or more medications in the medication regimen. In embodiments, allowing for the summing of the daily medication adherence for each of the or the or more medications in a regimen, allows for a singular value which efficiently represents adherence for the whole regimen. This allows for an efficient and quick monitoring of a prescribed regimen, instead of straining resources, such as time, to look at compliance for each individual medication.
Continuing the example from step 208, the daily regimen adherence (DRA) is a sum of DDA for medications D[i,j], D[i,j+1] . . . D[i,n#i].
In step 212, method 200 includes calculating a daily regimen baseline value (DRB)by re-calculating the daily regimen adherence value by utilizing a maximum potential value for the drug adherence count for each of the respective medications in the regimen associated with the patient. Accordingly, the daily regimen baseline value represents a value that would be achieved if there was ideal compliance to dosage and ideal compliance to time. This metric allows for contextualization of patient behavior in light of the prescribed medication regimen. An ideal patient should have equal values for both the daily regimen adherence value and the daily regimen baseline value.
As an example, a maximum value is assumed for DAC in DDA=DAC×DIF. Then the newly calculated DDAs are summed as in the case of calculating DRA for calculating the daily regimen baseline value (DRB).
In step 214. method 200 includes determining a medication adherence value (DA) based on the daily regimen adherence value and the daily regimen baseline value. For example, a ratio of the daily regimen adherence value and the daily regimen baseline value may serve as the medication adherence value. In instances, the determined ratio may be multiplied by a constant factor to ensure that the medication adherence value (DA) is an integer. For example, the following equation may be utilized:
DA=(DRA/DRB)×10
Accordingly, as an example if the DRA is 7 and the DRB is 10, the medical adherence value will be 7
In step 216, method 200 includes comparing the medication adherence with a threshold value. A threshold value may be set for a level where the clinical medical intervention may be necessary. For example, if a medical adherence value under 8 may have short-term or long-term consequences, than a threshold value of 8 may be set. This value may be set by a physician, based on clinical data, application of learning algorithms on clinical data (whether the patient's or broader set of patients), or a function of a combination of a physician's recommendations along with clinical data.
In additional embodiments, multiple threshold values may be set to which the medical adherence value is compared. For example, a first threshold value may be a critical value which represents a serious lapse in adherence, which requires urgent intervention. A second threshold value may be an adherence value which is not critical but still of medical concern. For example, on a scale of 0-10, a value of 3 may be a critical value under which the adherence value must not drop. If it does, then the patient may require serious immediate care. On the other hand, a value of 8 may be significant enough to require investigation of possible intervention.
In step 218, method 200 includes generating a notification when the medial adherence value is less than the threshold value. In detail, once it is determined that the medication adherence value is less than the threshold value a notification may be generated that may be then provided to the patient or other concerned entities such as pharmacists, physicians, and clinicians, etc. The notifications may serve as reminders as well as instruments to force reconsideration of treatment plans and interventions.
In additional embodiments, medication adherence may be calculated for successive days. Thereafter, processor 110 may then calculate a variation of the medical adherence over successive days. A rise or drop over a threshold amount on successive days may also trigger a notification, since the rise or drop may indicate that a patient is not maintaining a stabilized dosage. The notification may prompt an intervention including prompting another literacy survey, in response to which a physician may personally intervene.
While the method 200 is explained with respect to a daily time period, the same principles may be applied to calculate a medical adherence for any user-selected time period including a week, a month, etc. The principle of the present disclosure may be used to monitor patient adherence to any medical regimen, including but not limited to,diagnostic testing, exercise, diet, etc.
In further embodiments, medical adherence values may be utilized in combination with other such self-management scores to obtain an overall health management score. Analytics framework may provide relationships between such scores for a patient, in order to identify violating parameters and correct them—all with the use of a single dashboard displaying these scores. Hence, exemplary embodiments aid in reducing the time for customers and physicians to make decisions about clinical issues, as well as enhancing accuracy of clinical decisions. Embodiments of the present disclosure are disease and population size agnostic, and therefore have applicability across the spectrum of healthcare matters.
In some embodiments, data related to a patient's medical adherence may be parsed and cleansed to comply with HIPPA privacy guidelines. Thereafter, the data may be provided to pharmaceutical companies or other entities to use behavioral data to modify their products and/or recommendations.
In additional embodiments, in addition to providing a physician information about a patient's medical adherence, modeling systems based on user behavior may be utilized to provide treatment recommendations to physicians. For example, providing suggesting to physician regarding medication that have a high level of medical adherence.
