Psoriatic arthritis (PsA) is a chronic multisystemic disease requiring ordinary doctor visits and an adherence to medication. Evaluating the parameters affecting the medication adherence is essential for the efficacy of the treatment. To our knowledge no study has ever evaluated the factors affecting the medication adherence in patients with PsA so far.
Psoriatic arthritis (PsA) is a multisystemic disease requiring ordinary doctor visits and an adherence to medication. Due to its chronic nature treatment regimens lasts for the lifetime and that may affect the efficacy of the treatment. Although treatment with drugs is a biological intervention, medication adherence and eliminating the factors affecting it seems essential for treatment efficacy. To our knowledge no study has ever evaluated the factors affecting the medication adherence in patients with PsA so far. Our aim in this study is to evaluate the factors affecting the medication adherence in patients with PsA.
