ACR RADPEER Committee White Paper with 2016 Updates: Revised Scoring System, New Classifications, Self-Review, and Subspecialized Reports.

The ACR's RADPEER program is currently the leading method for peer review in the United States. To date, more than 18,000 radiologists and more than 1,100 groups participate in the program. The ABR accepted RADPEER as a practice quality improvement in 2009, which can be applied toward maintenance of certification; there are currently over 2,200 practice quality improvement participants. There have been ongoing deliberations regarding the utility of RADPEER, its goals, and its scoring system since the preceding 2009 white paper. This white paper reviews the history and evolution of RADPEER and eRADPEER, the 2016 ACR Peer Review Committee's discussions, the updated recommended scoring system and lexicon for RADPEER, and updates to eRADPEER including the study type, age, and discrepancy classifications. The central goal of RADPEER to aid in nonpunitive peer learning is discussed.
