OBJECTIVES: The Center for Medicare & Medicaid Services aims to improve the quality of care and overall health status of Medicare beneficiaries. This study demonstrates a novel intervention, the Medication Adherence Tracker (MAT), which is a collaborative effort between a managed care organization and contracted primary care providers(PCPs) to address non-adherence through patient-specific interventions. The primary objective was to examine the intervention effect on refill rates for statin medications using a mixed-effect model among patients enrolled in the MAPD Coverage plan. METHODS: Data was collected by a large managed care health plan. Pharmacy reports were provided to PCPs through the embedded nurse team. The intervention was carried out by the PCP’s office. Retrospective analysis was performed on contracted PCPs practicing in South Texas who participated in the MAT initiative from June to December 2017. Non-adherent MAPD beneficiaries, defined as having their year-to-date proportions of days covered rate below 80%, and under the care of these PCPs, were included. The logistic mixed-effect model was used to determine the association between the intervention and outcome, adjusting for predictors at two levels (physician and patient). RESULTS: Of the 2,194 patients with new claims, 69.87% were females, 67.74% used both: anti-diabetic and anti-hypertensive medications and had a mean age of 73.29 years. When the PCP’s office intervened in at least 80% of their non-adherent patients, those patients were 2.5 times more likely to refill their prescription post-intervention(CI:1.68-3.94,p<0.0001) as compared to patients under the care of PCPs who contacted less than 40% of their non-adherent patients. Every additional year of the physician’s experience increased the odds of refilling the prescription by 2%(OR=1.02,CI:1.01-1.03,p=0.0013). CONCLUSIONS: Refilling statin prescriptions in previously non-adherent patients was strongly associated with greater physician experience (years of practice) and higher percentage of physician outreach. Increasing physician involvement in closing the non-adherence gap can lead to improved adherence.
