Importance There is a need to define which outcomes matter to patients with psoriasis to deliver value for the patient when managing their condition. Objectives To generate a comprehensive overview of all outcomes relevant in the management of psoriasis as defined by patients. Evidence Review A systematic review was performed by searching 3 databases (MEDLINE, Embase, and Web of Science) from August 1, 2019, until March 27, 2021, using a comprehensive search strategy consisting of 4 concepts including psoriasis, patients, outcomes, and relevance. A (citing) reference search was also performed of all retrieved articles. Two independent reviewers screened the retrieved records by title/abstract against the eligibility criteria. Studies were eligible for inclusion if they reported on the importance of outcomes for patients with psoriasis. No language restrictions were used. Data extraction and quality assessment were also performed independently. Quality assessment was done using the QUALSYST tool. Findings In total, 10 365 records were screened for eligibility, of which 24 studies were included for synthesis. A total of 23 317 patients were evaluated, and 273 (154 unique) items were retrieved. These items were aggregated into 23 outcomes: (almost) complete clearance; symptom control; difficult location clearance; time to clearance; treatment efficacy, sustainability, safety, tolerability, and convenience; comorbidity control; daily and social activity; emotional well-being; intimate relationships; productivity; health-related quality of life; confidence in care; control of disease; communication with care professional; information from other sources than care professional; and cost of care (societal and for the patient). These were then further grouped into 4 core areas: physical/clinical, life impact, resource use, and adverse effects. The mean overall quality of the studies was 75.6% (range, 35.7%-100%). Conclusions and Relevance This systematic review analyzed patient-relevant outcomes reported in patients with psoriasis to aid in the transition to a value-based treatment approach.
