Abstract

Background: The appointment-based model (ABM) is a framework for medication synchronization (med sync) which allows improved efficiency in pharmacy operations. Refill alignment forms the foundation of med sync programs and has proven to improve medication adherence. However it is uncertain if the remaining four components of ABM including the identification and enrollment of patients, medication review and patient assessment, preparation of medications, and delivery of medications can positively impact adherence.

Objective: To identify ABM core component(s) that significantly improve medication adherence and evaluate the extent to what prescription volume utilizing ABM impacts adherence.

Methods: A retrospective, cross-sectional analysis was conducted on 68 community pharmacies. Medication adherence rates were collected for antihypertensive, antihyperlipidemic, and oral hypoglycemic agents. Analyses were performed to determine the impact of ABM operations on adherence.

Results: Four components of ABM were associated with significant improvement in adherence. The ABM operations related to those components include patient recruitment, medication delivery, flexible payment options, documenting synchronized medications and refill date, assessing patient ability to fill medications prior to refill date, refill timelines, and inquiring about medication changes during the patient outreach call (p < 0.05). While synchronizing at least 16% of a pharmacy's total prescription volume improved adherence, synchronizing at least 31% produced significant improvement across all chronic disease categories (p < 0.05).

Conclusion: Operationalization of four core components from the ABM process - identifying and enrolling patients, medication review and assessment, alignment of refills and preparation of medications - were all found to significantly improve adherence. Pharmacies wanting to improve adherence rates across chronic disease categories should aim to have a minimum of 31% of their prescription volume synchronized.
