Frequency and Clinical Utility of Alerts for Intra-Institutional Radiologist Discrepant Opinions.
Journal of the American College of Radiology : JACR 2023 Februrary 24
OBJECTIVE: Determine the rate of documented notification, via an alert, for intra-institutional discrepant radiologist opinions and addended reports, and resulting clinical management changes.
METHODS: This Institutional Review Board-exempt, retrospective study was performed at a large academic medical center. We defined an intra-institutional discrepant opinion as when a consultant radiologist provides a different interpretation from that formally rendered by a colleague at our institution. We implemented a discrepant opinion policy requiring closed-loop notification of the consulting radiologist's second opinion to the original radiologist, who must acknowledge this alert within 30 days. This study included all discrepant opinion alerts created 10/1/19-12/31/21, of which two radiologists and an internal medicine physician performed consensus review. Primary outcomes were degree of discrepancy and percent of discrepant opinions leading to change in clinical management. Secondary outcome was report addendum rate compared to an existing peer learning program using Fisher's exact test.
RESULTS: Of 114 discrepant opinion alerts among 1,888,147 reports generated during the study period (0.006%), 58 alerts were categorized as major (50.9%), 41 moderate (36.0%), and 15 as minor discrepancies (13.1%). Clinical management change occurred in 64/114 cases (56.1%). Report addendum rate for discrepant opinion alerts was 4-fold higher than for peer learning alerts at our institution (66/315=21% vs. 432/8273=5.2%%; p<0.0001).
DISCUSSION: Although discrepant intra-institutional radiologist second opinions were rare, they frequently led to changes in clinical management. Capturing these discrepancies by encouraging alert use may help optimize patient care and document what was communicated to the referring or consulting care team by consulting radiologists.
