OBJECTIVES: To understand the impact of prescription synchronization, offered through the ScriptSync(R) program at CVS pharmacies nationwide, on adherence and reducing visits to the pharmacy. DESIGN: Cohort study, conducted between March 26, 2015, and December 18, 2015. Program enrollment occurred in August 2015, with a 120-day baseline period preceding enrollment and a 120-day follow-up period. SETTING AND PARTICIPANTS: CVS retail community pharmacies across the United States. CVS Pharmacy patients voluntarily enrolling in the prescription synchronization program at CVS retail community pharmacies across the United States who filled 3 or more eligible prescriptions before program enrollment. The study included 126,597 patients who enrolled in the program and 81,355 patients who enrolled after the study enrollment period. OUTCOME MEASURES: Adherence was defined as the medication possession ratio. The average number of pharmacy visits per month was a second outcome measure. RESULTS: Exposed patients had a 7.5 percentage point adherence improvement (from 79.6% to 87.1%), compared with a 2.8 percentage point improvement among the unexposed (from 78.1% to 80.9%) for a benefit of 4.7 percentage points (P < 0.0001). Among patients with adherence opportunities, the net impact on adherence was 10.6% (P < 0.0001). The program resulted in 0.17 fewer visits per month (P < 0.0001). CONCLUSION: Offering prescription refill synchronization at a large national retail pharmacy chain resulted in improved adherence and fewer visits to the pharmacy in the 4 months following ScriptSync enrollment. Prescription refill synchronization programs should be considered in the care of patients with multiple comorbidities.
