Objective:
The purpose of this study was to transition from a traditional score-based peer-review system to an education-oriented peer-learning program in our academic abdominal radiology practice.
Material And Methods:
This retrospective study compared our experience with a score-based peer-review model used prior to September 2020 and a peer-learning model implemented and used exclusively beginning in October of 2020. In peer review, a web-based peer-review tool randomly generated a list of cases, which were blindly reviewed in consensus. Comparison of the consensus interpretation with the original report was used to categorize each reviewed case and to calculate the rates of significant and minor discrepancies. Only cases with a discrepancy were considered to represent a learning opportunity. In peer learning, faculty prospectively identified and submitted cases for review in several categories, including case interpretations with a discrepancy from subsequent opinion or result, interpretations considered to represent a great call, and interesting or challenging cases meriting further discussion. The peer-learning coordinator showed each case to the group in a manner which blinded the group to both submitting and interpreting radiologist and invited discussion during various stages of the case.
Results:
During peer review, a total of 172 cases were reviewed over 16 sessions occurring between April 2016 and September 2020. Only 3 cases (1.8%) yielded significant discrepancies whereas 13 (7.6%) yielded minor discrepancies, representing a total of 16 learning opportunities (3.6 per year). In peer learning, 64 cases were submitted and 52 reviewed over 7 sessions occurring between October 2020 and October 2021. 29 (56%) were submitted as an interesting or challenging case meriting further discussion, 18 (35%) were submitted for a discrepancy, and 5 (10%) were submitted for a great call. All 52 presented cases represented learning opportunities (48 per year).
Conclusion:
An education-focused peer-learning program provided a platform for continuous quality improvement and yielded substantially more learning opportunities compared to score-based peer review.
