What it does
Utilizes a simplified medication regimen protocol paired with an operant conditioning paradigm to significantly improve medication adherence, as well as establish a metric for medication adherence, create a database to protect providers against medical malpractice, and live assessment of whether a treatment plan is working or not.
In order to simplify the medication regimen, we use an evidence-based approach that utilizes a tool called a medication grid. This grid works with a notification system that not only reminds the patient when to takes their medication, but makes it easier to understand what they have to take.
Operant conditioning is achieved based on machine learning forecasting of risk of coronary events (primarily myocardial infarction and CVD-related death), as determined by latent variable analysis. Patient systolic and diastolic blood pressure data is pooled into risk categories, who's bounds are defined by a Bayesian learning model initialized to the current literature. As we obtain our user population's demographics and mortality data, this data serves as posterior evidence into our model and update bounds accordingly. Thus, risk is individualized based on patient's personal characteristics and health related behaviors. Once forecasted risk is determined, it is communicated to the patient in simple, effective visuals that will reinforce medication adherence. In addition, forecasted risk is assessed next to a null hypothesis of risk decrease with 100% adherence to treatment. This serves to determine whether or not the degree of medication adherence corresponds with degree of improvement in forecasted risk, as well as if the current treatment plan is effective.
