Statin adherence in patients enrolled in the disease management program for coronary artery disease – comparison between patients’ and general practitioners’ self-reports and patient records
Abstract Introduction Patients with coronary artery disease (CAD) should take a statin daily for secondary prevention. However, statin adherence in patients with CAD is low. This study investigated the proportion of adherent patients enrolled in the disease management program for CAD (DMP-CAD). Adherence was examined by comparing patients’ self-reports, general practitioners’ (GPs) self-reports, and prescription data. Methods Between October 2019 and March 2020, all patients enrolled in the DMP-CAD in three GP practices in Germany were invited to participate in the study. Participants completed a questionnaire on the tolerability of statins. Further, prescription data from patient records, low-density lipoprotein (LDL) levels, and GPs’ assessment of statin adherence were examined. The Medication Possession Ratio (MPR) served as a measurement tool for adherence. Results Seventy-four patients were included. MPR showed high statin adherence for most patients (83.8%). However, GPs did not reliably identify non-adherence in their patients. Generally, the mean LDL values were above the guideline recommendations (97.7 ± 27.9 mg/dl), with higher values in the non-adherent (123.6 ± 42 mg/dl) than in the adherent group (93.1 ± 22 mg/dl). Non-adherent patients were more likely to be employed (41.7% vs. 11.3%). Discussion Patients in this study showed high statin adherence. However, the LDL target value was often not reached. Therefore, GPs should take advantage of the good adherence of their patients and try to lower LDL levels by adjusting the dosage and/or changing the statin prescribed. Future studies should investigate typical characteristics of non-adherent patients in DMP-CAD so that GPs can target these patient groups and improve their adherence.
