Albertini JG, et al. - In this nonrandomized controlled intervention study including 2329 US surgeons, researchers assessed if confidentially sharing stages-per-case performance data with individual surgeons benchmarked to their peers nationally (a behavioral intervention) could be effective at reducing extreme overuse in Mohs micrographic surgery (MMS). The physicians affiliated with the American College of Mohs Surgery were included in the intervention group and physicians not affiliated with the American College of Mohs Surgery were considered as controls. An immediate and sustained reduction in mean stages per case, as well as an associated cost saving, was reported among outlier physicians as a consequence of sharing individual reports of MMS practice patterns with physicians as compared with physicians who did not receive these reports.
