Medication synchronization adoption and pharmacy performance

While medication synchronization programs are becoming a staple in community pharmacies, a standard process needs to be identified to provide consistent positive outcomes. Many studies demonstrate how medication synchronization affects individual level patients but have not examined how medication synchronization affects the pharmacy's performance. Because community pharmacies are calibrated based on performance to adherence measures for all patients, it is important to understand whether resource-intensive interventions, such as medication synchronization, lead to improved performance.

The aims of this study were to 1) examine pharmacy characteristics associated with medication synchronization adoption and 2) examine whether medication synchronization is associated with pharmacy-level performance on select medication adherence and utilization measures.

This study used a cross-sectional design. Community pharmacies participating in the North Carolina Community Pharmacy Enhanced Services Network (NC CPESN℠) program were included in this study. Pharmacy performance was measured as summary score of pharmacy's performance on seven risk-adjusted measures which were used to measure pharmacy's performance in the program. Adoption of medication synchronization was measured as a binary variable capturing whether the pharmacy offered med sync at the time the survey was administered.

Surveys were received from 160 out of 268 participating pharmacies (59.7% response rate) with a total of 155 pharmacies being included in the analytic sample. Pharmacies that adopted medication synchronization were more likely to have a clinical pharmacist on staff (c = 5.4, p = 0.019). Holding all else constant, medication synchronization adoption was not significantly associated with total medication adherence performance (p = 0.371).

Medication synchronization has proven successful in improving individual patient level adherence but may not change a pharmacy's overall performance in adherence for all patients. Further research is needed to examine how effective implementation might contribute to whether a medication synchronization program leads to meaningful gains in adherence for all patients.
