Does Patients' Perception of Improvement following a Pain Management Programme, Match Reported Minimally Clinically Important Differences?
Clinical outcomes for patients attending a pain management programme were evaluated to determine whether patients who rated an improvement on a Global Impression of Change Score, achieved mean changes in BPI that were consistent with 'acceptable' change, and to determine mean changes on other outcomes in this population. It is suggested that a mean change of 2.09 in pain interference, as measured by the Brief Pain Inventory (BPI), could be considered acceptable to patients. Currently data is unavailable for changes in pain acceptance.
