Pharmacy claims data as a tool to measure adherence

Abstract

Medication possession ratio (MPR) was introduced as a uniform methodology for estimating medication adherence from pharmacy claims data, but it does not provide accurate information on the continuity of medication usage and the measurement of medication persistency and identification of eventual gaps in medication supply. The combination of an MPR and a persistency metric could provide timely information on the dynamics of patient medication adherence.
