The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA)-Outcome Measures in Rheumatology (OMERACT) Psoriatic Arthritis (PsA) Core Set working group is in the process of selecting core instruments for PsA clinical trials. During a 2-h workshop and breakout group discussions at the GRAPPA 2017 annual meeting in Amsterdam, the Netherlands, participants discussed the first set of candidate instruments to be taken through the OMERACT Filter 2.1 instrument selection process: 66/68 swollen/tender joint count (66/68JC), Spondyloarthritis Consortium of Canada (SPARCC) enthesitis index, patient's global assessment (GRAPPA and OMERACT formulations), Health Assessment Questionnaire-Disability Index (HAQ-DI), Psoriatic Arthritis Impact of Disease (PsAID) questionnaires 9 and 12, and Functional Assessment of Chronic Illness Therapy (FACIT) Fatigue. Based on the assessment of domain match (content and face validity) and feasibility according to the OMERACT instrumen...

To identify a core set of domains (outcomes) to be measured in psoriatic arthritis (PsA) clinical trials that represent both patients' and physicians' priorities. We conducted (1) a systematic literature review (SLR) of domains assessed in PsA; (2) international focus groups to identify domains important to people with PsA; (3) two international surveys with patients and physicians to prioritise domains; (4) an international face-to-face meeting with patients and physicians using the nominal group technique method to agree on the most important domains; and (5) presentation and votes at the Outcome Measures in Rheumatology (OMERACT) conference in May 2016. All phases were performed in collaboration with patient research partners. We identified 39 unique domains through the SLR (24 domains) and international focus groups (34 domains). 50 patients and 75 physicians rated domain importance. During the March 2016 consensus meeting, 12 patients and 12 physicians agreed on 10 cand...

Background: In recent clinical trials in patients with psoriatic arthritis (PsA), the response criteria and disease activity measures that have been used were those developed for rheumatoid arthritis. However, these have not yet been validated in PsA. Objective: To compare the responsiveness and discriminative capacity of the psoriatic arthritis response criteria (PsARC), American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR) response criteria and the Disease Activity Score (DAS) and core-set measures in patients with PsA and peripheral arthritis, using the data from two randomised placebo-controlled trials of tumour necrosis factor inhibitors. Methods: In an infliximab trial, 104 patients with active PsA were randomised to receive placebo or infliximab for 16 weeks. In an etanercept trial, 60 patients with active PsA were randomised to receive placebo or etanercept for 12 weeks. Data from baseline and the end of the intervention phase were used from each study. Responsiveness was assessed using the standardised response mean and effect size. Capacity to discriminate between the active drug and placebo was assessed using t values or a x 2 test. Measures were ranked in order of their t value or x 2 value. Results: The EULAR criteria performed better in discriminating the active drug from placebo than the ACR20 improvement criteria, which in turn performed better than the PsARC. It was also found that the pooled indices (DAS and DAS28) were generally more responsive, and performed better in discriminating active drug from placebo, than the single core-set measures. Conclusion: Response criteria and pooled indices developed for rheumatoid arthritis are useful for the assessment of arthritis in PsA clinical trials.

This module reflected work within the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) to develop and validate composite disease activity measures in psoriatic arthritis (PsA). At the Outcome Measures in Rheumatology (OMERACT) 8 Meeting, a core set of domains to be assessed in randomized controlled trials (RCT) and longitudinal observational studies of PsA was agreed upon. At OMERACT 10, 5 proposed composite responder definitions for PsA were reviewed and discussed, including new data from the GRACE (GRAppa Composite Exercise) study. At OMERACT 11, ongoing retrospective analyses of RCT data using the 3 proposed measures (Composite Psoriatic Disease Activity Index, Psoriatic Arthritis Disease Activity Score, and Arithmetic Mean of the Desirability Function) were discussed in detail. There was agreement that developing composite outcome measures for use in RCT and longitudinal observational studies in PsA was important. Concerns were expressed regarding ...

Objective The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) and Outcome Measures in Rheumatology (OMERACT) psoriatic arthritis (PsA) working group is developing a Core Outcome Measurement Set for PsA clinical trials [randomized controlled trials (RCT) and longitudinal observational studies (LOS)] using the OMERACT Filter 2.1 instrument selection algorithm. Our objective was to assess the Psoriatic Arthritis Impact of Disease questionnaire (PsAID12) for the measurement of the core domain PsA-specific health-related quality of life (HRQOL). Methods PsAID12 measurement property evidence gathered in a systematic literature review, and additional analyses conducted in LOS, were used to inform a consensus process. Analyses that had not been published were independently reviewed by the OMERACT technical advisory group. Data and process were presented, discussed in breakout groups, and voted on at the OMERACT conference (Terrigal, Australia, May 2018). Resu...
Defining Outcome Measures for Psoriatic Arthritis: A Report from the GRAPPA-OMERACT Working Group
The Journal of rheumatology, 2017
The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA)-Outcome Measures in Rheumatology (OMERACT) Psoriatic Arthritis (PsA) Core Set working group recently published the updated 2016 psoriatic arthritis (PsA) core domain set, a set of disease features that should be measured in all clinical trials. At the GRAPPA annual meeting in July 2016, the PsA working group presented the updated PsA core domain set endorsed by 90% of participants at OMERACT in May 2016 and drafted a roadmap for the development of the PsA core outcome measurement set. In this manuscript, we review the development process of the PsA core domain set and the ongoing and proposed work streams for development of a PsA core measurement set.
