In plenary and breakout sessions at the GRAPPA annual meeting (Boston, September 2007), the current status of measures used in clinical trials was reviewed, and development of simplified measures for use in various types of clinical practice (rheumatology, dermatology, and general practice) was discussed. We present a review of those discussions.
