Community Pharmacy Medicare Part D Consultations: Plan-Switching Decisions and Chronic Medication Adherence

Abstract

Objectives: (1)To compare Part D plan switching for users and nonusers of a pharmacy-led Medicare Part D consultation service and (2) to evaluate the effect of service use on chronic medication adherence. Methods: This was a longitudinal study, occurring in one independently owned community pharmacy in Iowa. Medicare Part D beneficiaries who used the service were compared to nonusers. Dispensing data were used to compare planswitching and the effect of service use on chronic medication adherence between service users and nonusers. Proportion of days covered (PDC) was used to evaluate medication adherence. Results: In the 2017 and 2018 plan year, 79 and 138 Medicare beneficiaries used the service, respectively. These individuals were compared to 849 Medicare beneficiaries and a random sample of 101 beneficiaries in respective years. The respective switching rates for service users in 2018 and 2019 plan year were 43% and 15.9%, compared to 4% switching rates in both years for nonusers. Using the Medicare Part D consultation yielded a statistically significant positive effect on switching in both plan years (P values
