Overview
Brief Summary
This study will compose a national database of drug adherence and investigate the factors that affect drug adherence in patients taking new oral anticoagulation therapy in Turkish Population.
Detailed Description
NOACs have several clinical and pharmacological advantages over warfarin however suboptimal adherence is one of the most common causes of failure to respond to medications and outcomes. This observational multicenter, retrospective study, will compose a national database of drug adherence and investigate the factors that affect drug adherence in patients taking new oral anticoagulation therapy in Turkey. Social support and adherence to therapy factors that may affect drug adherence and adverse events will be assessed by self-report questionnaires. Non-adherence will be tested for demographic, clinical, awareness of NOAC therapy and socioeconomic factors.

Outcomes
Primary Outcomes
Compliance of NOACs in Turkish Population
Time Frame: 10 months
Factors that may affect drug adherence and adverse events will be assessed by self-report questionnaires. Non-adherence will be tested for demographic, clinical, awareness of NOAC therapy and socioeconomic factors. The validity of the Morisky Adherence Scale had already been demonstrated with regard to medication adherence in patients receiving vitamin K antagonists. An extended 8-item Morisky scale was used instead of the original 4-item Morisky scale in order to better identify the situations and the conditions that could affect medication adherence and to better assess the psychometric features.The reliability and the validity of the 8-item Morisky Adherence Scale translated into Turkish had been demonstrated in Turkish population by previous studies.
