Résumé / Abstract

We determined the knowledge and skills associated with medication adherence for 61 heart failure patients over the age of 5 0. Adherence data were collected using electronic medication event monitoring systems, pharmacy refills, and participants' self-report. Only 20% of participants correctly remembered their medications' indications, but larger proportions could read prescription labels (62%), distinguish tablet and capsule colors (54%), and open medication bottles with flip-top lids (100%), and knew the medication dosages (66%) and administration times (49%). We modeled the effects of knowledge and medication skills on medication adherence while controlling for demographics. The final mixed effect multiple logistic model contained knowledge of correct dosing times (p= 0.001) and reading ability (p=0.029) as the best predictors of medication adherence. Our assessments and model identified patient-specific barriers to adherence and predicted patients at risk of poor adherence who may be targets of an intervention.
