Abstract

Aims: Little is known about usual care by physicians and pharmacy teams to support adherence to statins and whether the extent of this care is associated with adherence to statins. Objective of the study was to examine the relationship between the extent of adherence supporting activities of HCPs and patients’ adherence to statins. Methods: Cross-sectional study in 48 pharmacies and affiliated physicians’ practices, between September 3, 2014 and March 20, 2015. Patients visiting the pharmacy with a statin prescription from participating prescribers were invited to participate. Usual care to support adherence was assessed among HCPs with the Quality of Standard Care questionnaire about usual care activities to support adherence. Adherence to statins was assessed among patients with the MARS-5 questionnaire. The association between the extent of HCPs’ adherence supporting activities and patients’ adherence was examined by means of multilevel regression analysis. Results: 1,504 patients and 692 HCPs (209 physicians, 118 pharmacists and 365 pharmacy technicians) participated. No association was found between the extent of physicians’ adherence supporting activities and patients’ adherence to statins. The extent of adherence supporting activities by pharmacy teams in usual care was negatively associated with patients’ adherence to statins (B coefficient -0.057 (95%CI: 0.112-0.002). Conclusions: This study suggests that there is no positive relationship between the extent of HCPs’ adherence supporting activities in usual care and patients’ adherence to statins. Other methods than questionnaires (e.g. electronic monitors (to assess adherence) and observations (to assess usual care) should be applied to confirm the results of this study
