Medication Adherence in Psoriatic Arthritis

Summary

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.

Interventions

OTHER

Disease activity in psoriatic arthritis (DAPSA)

DAPSA includes a 68/66 joint count summed with a patient global, patient pain score, and C- reactive protein level. The DAPSA provides a continuous score of arthritis activity and has validated cut points for remission (\< 4) and low disease activity (\< 14).

OTHER

Compliance-Questionnaire-Rheumatology (CQR)

The CQR is a self-administered questionnaire that was developed with the aim of correctly identifying patients that were classified as "low" adherers (taking \<80% of their medication correctly). The four point Likert answering scale ranges from; "Definitely don't agree" (scored 1) to "Definitely agree" (scored 4) with lower scores indicating lower levels of adherence. Total score is between 0 and 100.

The Psoriatic Arthritis Quality of Life (PsAQoL)

The Psoriatic Arthritis Quality of Life (PsAQoL) measure is a disease specific patient-reported outcome measure which measures the effect that psoriatic arthritis has on a patient's quality of life. It is a self-administered, 20-item questionnaire that takes about three minutes to complete. The answers are restricted to true or false.A high score on the PsAQoL indicates a lower quality of life.
