title: Outcome measures for acute and chronic gout.
abstract: Gout provides some unique challenges in classification and measurement of outcomes. Our aim was to evaluate criteria for classification and to develop and validate optimal instruments to measure outcomes for acute and chronic gout. A planning committee and interested attendees met to propose classification criteria and domains for outcomes. Seven of the current American Rheumatism Association preliminary criteria for classification were proposed as the best current criteria for acute gouty arthritis, pending further studies. The presence of gout is best established by crystal identification, although this technique has limitations. Five domains for acute gout outcomes and 9 for chronic gout were identified along with proposed instruments for testing and validation. The unique problems of gout evaluation can and will be addressed.
