Abstract
Systems and methods are provided for managing medical adherence. An exemplary method may include managing medical adherence utilizing data aggregating and processing to determine impact on a user's health based on their behavior related to prescribed medication. The method may entail utilizing data related to a medication regimen and patient behavior to determine a patient's compliance to the regimen in terms of dosage and time. These values may be utilized to calculate a medical adherence value representing a patient's adherence to a prescribed regimen. Responsive to determining low medical adherence, a notification may be generated which may result in an intervention with the patient.
Core Innovation
The invention is a computer-implemented adherence management system that manages a user's adherence to a prescribed regimen by receiving data related to the user and information related to the prescribed regimen having one or more items or steps relating to medication, diagnostic testing, exercise, and diet, where a respective literacy level is associated with each of the one or more items or steps. The data related to the user includes blood glucose levels measured by a blood glucose monitor, and the medication includes insulin.
The system calculates a literacy level based on a survey completed by the user, based on an accuracy of data input by the user into an electronic device, and based on whether the user did not enter certain data or entered erroneous data, wherein the literacy level is reduced in those cases. The system calculates compliance to quantity and compliance to time for each of the one or more items or steps based on the received data, including compliance to time for medication by determining whether the user consumed a given medication within a window of time.
The value of the window of time is based on expected timing of a future meal and a dosage of the given medication to be consumed. The system calculates an adherence count associated with each item or step by summing the compliance to quantity, the compliance to time, and the respective literacy level associated with the item or step, and then determines a daily adherence for each item or step and a daily regimen adherence value by summing daily adherence across all items or steps in the regimen.
The invention computes a daily regimen baseline value by re-calculating the daily regimen adherence value using a maximum potential value for the adherence count for each item or step associated with the user. The system determines an overall adherence value based on the daily regimen adherence value and the daily regimen baseline value, compares the overall adherence value with a threshold value, and generates a notification when the overall adherence value is less than the threshold. The generated notification is transmitted to the electronic device and contains one or more intervention options, including administration of a literacy survey and explanation to the user of benefits of following the prescribed regimen and impact of failure to follow the prescribed regimen.
Claims Coverage
This partial set includes three independent claims. Across these independent claims, the inventive features center on literacy-based adherence scoring, compliance to quantity and compliance to time using prescribed comparisons, aggregation into overall adherence with a baseline, threshold comparison, and conditional notification with intervention options; medication-time compliance is tied to an expected future meal and dosage.
Literacy level based on survey and input accuracy
Calculating the literacy level based on a survey completed by the user, based on an accuracy of data input by the user into an electronic device, and based on whether the user did not enter certain data or entered erroneous data, wherein the literacy level is reduced in those cases.
Compliance to quantity and compliance to time per item or step
Calculating a compliance to quantity and a compliance to time for each of the one or more items or steps based on the received data, wherein compliance to time for medication includes determining whether the user consumed a given medication within a window of time, wherein the value of the window of time is based on an expected timing of a future meal and a dosage of the given medication to be consumed.
Adherence count summing compliance and literacy
Calculating an adherence count associated with each of the one or more items or steps by summing the compliance to quantity, the compliance to time, and the respective literacy level associated with each of the one or more items or steps.
Overall adherence value from daily adherence and daily regimen baseline
Calculating a daily regimen adherence value by summing the daily adherence of all of the one or more items or steps in the regimen; calculating a daily regimen baseline value by re-calculating the daily regimen adherence value by utilizing a maximum potential value for the adherence count for each of the respective items or steps in the regimen associated with the user; determining an overall adherence value based on the daily regimen adherence value and the daily regimen baseline value; and comparing the overall adherence value with a threshold value.
Notification with intervention options when below threshold
Generating a notification when the overall adherence value is less than the threshold value; and transmitting the generated notification to the electronic device, wherein the generated notification contains one or more intervention options including administration of a literacy survey and explanation to the user, via the electronic device, of benefits of following the prescribed regimen and impact of failure to follow the prescribed regimen.
Across the independent claims, the central inventive combination is literacy-level computation from survey and data-entry accuracy, compliance-to-quantity and compliance-to-time per regimen item or step, aggregation via adherence count into daily regimen adherence, baseline computation using a maximum potential adherence count, calculation of an overall adherence value that is compared to a threshold, and generation/transmission of a notification that includes one or more intervention options when the overall adherence value is below the threshold.
Stated Advantages
Provides one or more intervention options when overall adherence is less than the threshold value, including administration of a literacy survey and explanation of benefits of following the prescribed regimen and impact of failure to follow the prescribed regimen.
Documented Applications
Managing adherence of a user having a blood glucose condition to a prescribed regimen for treating the blood glucose condition, where the medication includes insulin.
Managing adherence for a prescribed regimen including medication, diagnostic testing, exercise, and diet items or steps.
Managing adherence for a blood sugar condition identified as diabetes.
