Variables and data collection
Patient data were collected with a hardcopy questionnaire assessing socio-demographic characteristics, medication related information (duration statin use, prescriber) and patient’s adherence to statins (see measurement instruments). In this study implementation adherence (defined in the ABC taxonomy of medication adherence) was studied, as current statin users were included 27. Patients were asked by the dispensing pharmacy technician to fill out the questionnaire in the pharmacy or to return the questionnaire by mail. HCPs’ socio-demographic characteristics and HCPs’ usual care to support adherence (see measurement instruments) to statins were assessed using a hardcopy questionnaire.
