Improving Medication Adherence and Health Care Outcomes in a Commercial Population through a Community Pharmacy.

Abstract The aim was to evaluate the impact of a multifaceted set of medication management interventions offered by a community pharmacy on adherence, health care utilization, and costs within a commercial population. Patients initiating therapy within 16 drug classes from February 7, 2013, to October 6, 2013, were offered various adherence interventions by Walgreens pharmacy. Patients were linked deterministically to IMS medical and prescription databases for 6-month pre- and post-index data analysis. Walgreens patients (intervention) were matched to patients using other pharmacies (control) on drug class, index date, baseline demographics, clinical factors, utilization, and costs. Outcomes were evaluated at the intent-to-treat level using post-index differences and generalized estimating equations (GEE) regression model. Paired t tests (continuous variables) and McNemar's test (dichotomous variables) were used to determine the significance of estimated model coefficients at α = 0.05. The groups (n = 72,...
