title: Differential utility of medical procedures in the assessment of chronic pain patients.
abstract: Physicians are frequently called upon to evaluate patients with chronic pain to (1) establish the etiology, (2) determine the extent of impairment and disability, and (3) prescribe treatment. In many cases, there is little agreement as to what evaluation procedures should be used or how to weight and integrate these findings. Two studies were conducted to determine the domain of procedures pain specialists believe are most important in evaluation and the clinical utility of each. A survey of 75 physicians specializing in the treatment of chronic pain was conducted. Coefficients of concordance indicated that physicians displayed substantial agreement as to the differential utility of 18 physical examination and diagnostic procedures. The relevance of each of these procedures in the assessment of 100 pain patients was evaluated. Differential weights for each procedure derived from the survey were highly correlated with clinical practice. The results of the present studies provide a basis for development of a standardized assessment procedure that incorporates statistically derived weights to quantify medical findings.
