Resident pre-dictation of ED case delay signoff of those reports, but overall, residents improve report turnaround time

Purpose: In academic radiology departments, attendings and resident are increasingly working together overnight for Emergency Department (ED) radiology coverage. The purpose of this study was to quantify reporting turnaround time for overnight cases read by residents and for overnight shifts with residents on duty. Methods: A retrospective study was performed at a hospital system where one overnight attending covers two hospitals with a 2nd/3rd year overnight resident, and a second overnight attending covers two other hospitals 80% of the time independently and 20% of the time with a fourth-year resident. In the first analysis, the median difference in turnaround time, from the time when the case was completed by the technologist to the time the attending finalized it, between cases read independently by attendings and cases pre-dictated by residents was calculated. In the second analysis, the median difference in turnaround time for all cases performed at the second two hospitals was compared on nights when an attending was on duty alone versus nights when a fourth-year resident was also on duty, regardless of if the resident had pre-dictated the case. Results: For computed tomography (CT), radiographs (XR), and ultrasound (US), there was a significant delay in turnaround time for cases pre-dictated by residents compared to cases read independently by attendings, ranging between 11 and 49 min depending on resident seniority and modality (p ≤ 0.001). For all cases on nights with a 4th year resident working, overall median report turnaround time decreased by 7 min (p < 0.001). Conclusion: Resident pre-dictation causes delay in the finalization of individual CT, US, and XR reports; however, overall, working with residents results in a significant decrease in report turnaround time supporting the belief that overnight resident education does not delay patient care.
