Background: A new service model integrates the specialty pharmacy's comprehensive service with the retail pharmacy's patient contact, giving patients options for medication delivery to home, pharmacy, or doctor's office.
Objective: Evaluate the impact of the new service model on medication adherence.
Design: Retrospective cohort study
Settings: One hundred fifteen CVS retail stores in Philadelphia participated in a pilot from May 2012 to October 2013, and 115 matched CVS retail stores from around the nation served as controls.
Patients: All eligible patients from the intervention and control stores received specialty medications through CVS retail pharmacies prior to implementation of the new service model.
Intervention: The intervention patients were transitioned from retail pharmacy service to the specialty pharmacy with delivery options. The control patients received standard retail pharmacy services.
Main outcome measures: Proportion of days covered and first fill persistence were tracked for 12 months before and after program implementation.
Results: Under the new service model, 228 patients new to therapy in the post period had a 17.5% increase in the rate of obtaining a second fill as compared to matched controls. Patients on therapy in both the pre- and the post-periods had a pre-post increase of 6.6% in average adherence rates and a pre-post increase of 10.8% in optimal adherence rates as compared to 326 matched controls.
Conclusion: The study demonstrated significant improvement in both adherence to therapy and first-fill persistence among patients in the new service model integrating specialty pharmacy's comprehensive services with the retail pharmacy's patient contact and medication delivery choices.
