Two Delphi exercises were conducted among different groups of rheumatologists.

Cluster analysis and multidimensional scaling showed that these items clustered into 5 concepts (joint inflammation, severity of symptoms, stereotypical nature, pain, and gout archetype) distributed along 2 dimensions (objective to subjective features and general features to specific features of gout). Using this analysis, expert panel discussion generated a short list of potential features: joint swelling, joint tenderness, joint warmth, severity of pain, patient global assessment, time to maximum pain, time to complete resolution of pain, an acute\u2010phase marker, and functional impact of the episode.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A short list of features has been identified and now requires validation against a patient\u2010 and physician\u2010defined gout flare in order to determine the best combination of features.<\/jats:p><\/jats:sec>","DOI":"10.1002\/art.24166","type":"journal-article","created":{"date-parts":[[2009,3,31]],"date-time":"2009-03-31T01:47:56Z","timestamp":1238464076000},"page":"535-543","source":"Crossref","is-referenced-by-count":36,"title":["Toward a valid definition of gout flare: Results of consensus exercises using delphi methodology and cognitive mapping"],"prefix":"10.1002","volume":"61","author":[{"given":"W.
