Study Validates Optimal Medication Adherence

New research conducted by CVS Caremark (CVS) and Brigham and Women’s Hospital published in the January 2014 issue of the American Heart Journal, validates the effectiveness of a widely-used standard for optimal medication adherence. The study confirmed that patients need to achieve a Medication Possession Ratio (MPR) of at least 80 percent meaning they are adherent to 80 percent or more of their prescription medications in order to reduce their risk of hospital readmission after a heart attack. Patients with more moderate levels of medication adherence following a heart attack (60-79 percent MPR) derived less clinical benefit from their prescribed medications and had higher levels of disease-related clinical events. An MPR of 80 percent has long been considered optimal, but this threshold had little empirical support. Related: See NCPIE’s Be Medicine Smart
