    Abstract:
    PURPOSE: The objective of this paper is to assess the volume, accuracy, and timeliness of radiology resident preliminary reports as part of an independent call system. This study seeks to understand the relationship between resident year in training, study modality, and discrepancy rate. METHODS: Resident preliminary interpretations on radiographs, ultrasound, CT, and MRI from October 2009 through December 2013 were prospectively scored by faculty on a modified RADPEER scoring system. Discrepancy rates were evaluated based on postgraduate year of the resident and the study modality. Turnaround times for reports were also reviewed. Differences between groups were compared with a chi-square test with a significance level of 0.05. Institutional review board approval was waived as only deidentified data were used in the study. RESULTS: A total of 416,413 studies were reported by 93 residents, yielding 135,902 resident scores. The rate of major resident-faculty assessment discrepancies was 1.7%. Discrepancy rates improved with increasing experience, both overall (PGY-3: 1.8%, PGY-4: 1.7%, PGY-5: 1.5%) and for each individual modality. Discrepancy rates were highest for MR (3.7%), followed by CT (2.4%), radiographs (1.4%), and ultrasound (0.6%). Emergency department report turnaround time averaged 31.7 min. The average graduating resident has been scored on 2,746 ± 267 reports during residency. CONCLUSIONS: Resident preliminary reports have a low rate of major discrepancies, which improves over 3 years of call-taking experience. Although more complex cross-sectional studies have slightly higher discrepancy rates, discrepancies were still within the range of faculty report variation.
