Poor medication adherence limits the effectiveness of chronic illness management and control and increases the likelihood of hospitalizations, emergency room visits, and preventable disease progression. This study examines the medication possession ratio (MPR) for patients whose prescribing clinicians and case managers were messaged electronically about their patient not refilling his/her prescription. Compared to a control group, patients whose prescribers were notified had a significantly greater increase in MPR than a matched control group of patients whose prescribers did not receive notification. The increased MPR for the experimental group continued after the conclusion of the alerts but at not as high of a rate. This suggests that prescribers must be kept informed about medication adherence to achieve highest MPR for their patients. The study also showed a seasonal fluctuation in medication adherence rates, with patients adhering less during winter months. In summary, a low-touch, electronic-based medication adherence intervention can improve antipsychotic medication adherence rates.
