Introduction: Psoriatic arthritis (PsA) is a heterogeneous chronic disease with a significant patient-perceived impact leading to pain, fatigue, impaired function and quality of life and psychological distress. Remission is the announced treatment target in PsA. Several definitions of remission have been proposed including definitions on composite scores such as the Disease Activity in Psoriatic Arthritis (DAPSA) and Minimal Disease Activity (MDA), however their translation into the patient's perspective is lacking. Flares are frequent in PsA and are important for patients but are not well-defined from the physician's perspective. Although some work is ongoing regarding remission and flare from the patient's perspective, currently no information allows to cross-tabulate and compare the patient and physician perspectives regarding remission and flare in PsA .
