The appointment-based model (ABM) significantly improves medication adherence through patient enrollment, medication review, and synchronized refills. Achieving 31% prescription synchronization is key for widespread chronic disease adherence improvements.
Area of Science:
- Pharmacy Practice
- Medication Adherence Research
- Health Services Research
Background:
- The appointment-based model (ABM) enhances pharmacy efficiency through medication synchronization (med sync).
- While refill alignment is known to improve adherence, the impact of other ABM components remains unclear.
- Key ABM components include patient identification/enrollment, medication review, preparation, and delivery.
Purpose of the Study:
- To determine which ABM components significantly enhance medication adherence.
- To assess the relationship between prescription volume managed by ABM and adherence rates.
Main Methods:
- Retrospective, cross-sectional analysis of data from 68 community pharmacies.
- Collected medication adherence data for antihypertensive, antihyperlipidemic, and oral hypoglycemic agents.
- Analyzed the impact of specific ABM operations on adherence.
Main Results:
- Four ABM components were significantly associated with improved adherence: patient recruitment, medication delivery, flexible payments, and medication assessment/outreach.
- Synchronizing at least 16% of a pharmacy's prescription volume improved adherence.
- Synchronizing at least 31% of prescription volume led to significant adherence improvements across all studied chronic disease categories.
Conclusions:
- Implementing four core ABM components (patient identification/enrollment, medication review, refill alignment, medication preparation) significantly boosts medication adherence.
- Pharmacies aiming to improve adherence for chronic diseases should target synchronizing a minimum of 31% of their total prescription volume.
