Evaluating the Effects of a Medication Adherence Packaging Program on Outcomes in Older People.

Abstract

Objective To determine the impact of an adherence packaging and medication synchronization program on hospital visits for older people living independently in the community. Design A retrospective pre-post study that evaluated patient outcomes over a 24-month period was conducted. Patient-specific socio-demographic, medical, and hospital visit-related data were collected for 12 months before and after patient enrollment in the adherence packaging program. Setting The study was conducted at Rx Partners LTC, LLC, a University of Pittsburgh Medical Center (UPMC) pharmacy in Pittsburgh, Pennsylvania. Participants Patients 65 years of age or older, of any gender, with UPMC Health Plan insurance coverage, who enrolled in the adherence packaging program between July 2019 and December 2019. Intervention Enrollment in the adherence packaging program included medication synchronization and packaging in prefilled medication sets delivered to the patient's home monthly. Monthly medication reconciliation and review by clinical pharmacists was an included value-added service. Results Of the 92 patients included in the analysis, 60 had hospital visits during their pre-enrollment period for a total of 146 visits, compared with 54 patients in the postenrollment period totaling 126 visits; however, the mean rate of hospital visits was not statistically significant (1.59 versus 1.37; P = 0.48). Pharmacists prevented 1.87 medication errors/patient in the postenrollment setting. Conclusion Enrollment in the program was associated with fewer hospital visits, though not statistically significant, and pharmacists had abundant opportunity to prevent medication errors and optimize regimens. Further evaluation is warranted in a larger cohort.
