In 2016, members of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA), in collaboration with KPMG LLP (UK), conducted a study to measure care in psoriatic arthritis (PsA). A key finding was that centers do not usually have processes in place to measure the effect of improved quality of care. Our objectives were to identify and select best-practice indicators to enable PsA caregivers to assess and monitor the outcomes of specific initiatives aimed at improving care in 4 focus areas: (1) shortening time to diagnosis; (2) improving multidisciplinary collaboration; (3) optimizing disease management; and (4) improving disease monitoring.
(1) Structured review of scientific and grey literature to obtain evidence for a long list of 100 potential indicators across the 4 focus areas; (2) survey expert rheumatologists and dermatologists to review the long list and identify the most meaningful and feasible indicators for use in day-to-day practice; (3) consensus discussion to identify a shortlist of indicators based on predefined selection criteria; (4) electronic group discussion to refine definitions of shortlisted indicators and targets; and (5) review of the shortlisted indicators at the annual GRAPPA meeting in July 2018 to ensure the indicators meet the preliminary criteria.
The expert group arrived at a consensus with a shortlist of 8 best-practice indicators across 4 key focus areas aligned with the patient pathway.
There were 8 evidence-based best-practice indicators and respective targets that were identified to enable the monitoring of quality of care and target improvements.
