In plenary presentations, examples of composite measures developed for rheumatoid arthritis (RA) and ankylosing spondylitis (AS) were reviewed, followed by a presentation of the assessment of disease activity in systemic lupus erythematosus. Three recently devised composite methods of assessing activity or response in PsA also were presented. Considerable discussion followed in breakout groups, and members agreed that a new composite measure specifically for PsA is necessary. The composite measure should include components that encompass the spectrum of psoriatic disease, i.e., in addition to assessment of peripheral joints, it should include assessment of sacroiliitis, spondylitis, enthesitis, and dactylitis, as well as skin and nail disease.<\/jats:p>","DOI":"10.3899\/jrheum.090956","type":"journal-article","created":{"date-parts":[[2010,2,10]],"date-time":"2010-02-10T11:17:53Z","timestamp":1265800673000},"page":"453-461","source":"Crossref","is-referenced-by-count":21,"title":["Composite Measures in Psoriatic Arthritis: GRAPPA 2008"],"prefix":"10.3899","volume":"37","author":[{"given":"DAFNA D.","family":"GLADMAN","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ROBERT","family":"LANDEW\u00c9","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"NEIL J.","family":"McHUGH","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"OLIVER","family":"FITZGERALD","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"DIAMANT","family":"THACI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"LAURA","family":"COATES","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"PHILIP J.","family":"MEASE","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ABRAR A.","family":"QURESHI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"GERALD G.","family":"KRUEGER","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CHRISTOPHER T.","family":"RITCHLIN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ARTHUR F.","family":"KAVANAUGH","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"AMIT","family":"GARG","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2262","published-online":{"date-parts":[[2010,2,9]]},"reference":[{"key":"2018112909215966000_37.2.453.1","first-page":"579","article-title":"Development of a disease activity score based on judgment in clinical practice by rheumatologists","volume":"20","author":"van der Heijde","year":"1993","journal-title":"J Rheumatol"},{"key":"2018112909215966000_37.2.453.2","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2005.039859"},{"key":"2018112909215966000_37.2.453.3","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2005.042630"},{"key":"2018112909215966000_37.2.453.4","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2008.094870"},{"key":"2018112909215966000_37.2.453.5","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/keh624"},{"issue":"Suppl 3","key":"2018112909215966000_37.2.453.6","first-page":"71","article-title":"Assessment of flares in lupus (SLE) patients in a placebo-controlled randomized phase II\/III study of rituximab (EXPLORER) [abstract]","volume":"68","author":"Merrill","year":"2009","journal-title":"Ann Rheum Dis"},{"key":"2018112909215966000_37.2.453.7","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2006.051706"},{"issue":"Suppl 2","key":"2018112909215966000_37.2.453.8","first-page":"526","article-title":"Response criteria for psoriatic arthritis I: derivation of models for response [abstract]","volume":"67","author":"Gladman","year":"2008","journal-title":"Ann Rheum Dis"},{"issue":"Suppl 2","key":"2018112909215966000_37.2.453.9","first-page":"526","article-title":"Response criteria for psoriatic arthritis II: developing and comparing response criteria for PsA [abstract]","volume":"67","author":"Gladman","year":"2008","journal-title":"Ann Rheum Dis"},{"key":"2018112909215966000_37.2.453.10","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/ken406"},{"key":"2018112909215966000_37.2.453.11","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(07)61128-3"},{"key":"2018112909215966000_37.2.453.12","doi-asserted-by":"crossref","first-page":"238","DOI":"10.1159\/000250839","article-title":"Severe psoriasis \u00e2\u0080\u0094 oral therapy with a new retinoid","volume":"157","author":"Fredriksson","year":"1978","journal-title":"Dermatologica"},{"key":"2018112909215966000_37.2.453.13","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2004.04.012"},{"key":"2018112909215966000_37.2.453.14","doi-asserted-by":"publisher","DOI":"10.1002\/art.24562"},{"key":"2018112909215966000_37.2.453.15","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2133.2006.07389.x"},{"key":"2018112909215966000_37.2.453.16","doi-asserted-by":"crossref","unstructured":"Coates LC Fransen J Helliwell PS .
