Interpretation of Basic Clinical Images: How Are Surgical Residents Performing Compared to Other Trainees?

Background: During medical training students, residents, and fellows learn how to accurately interpret basic radiographic images. This skill is mostly utilized by physicians in the acute and critical care settings. It is unclear whether surgical residents' interpretation skills differ from that of other trainees.

Methods: A 30-question online quiz was developed to evaluate trainees' skills in interpreting images using various radiologic modalities. The participating cohort included (1) medical students (MS), (2) general surgery residents (GST), internal medicine residents and fellows (IMT), and radiology trainees (RT). The impact of residency specialty and level of training on performance was evaluated.

Results: A total of 69 postgraduate trainees and 19 MS enrolled in the online quiz. The average score was 67.6% (±16.6). GST scored higher than IMT (74.2% ± 10.7% vs. 67.9% ± 11.3%, p = 0.038); however, they were equally proficient to RT. MS had the lowest interpretation accuracy rates compared to postgraduate trainees (57.4% ± 16.8%, p < 0.001). On different radiographic modalities, junior GST performance was comparable to MS, JR-IMT, and Junior Radiology Trainees (JR-RT). On computed tomography (CT) body, GST (83.1% ± 15.7%) scored higher than IMT (70.3% ± 17.7%, p = 0.026) and MS (61.7% ± 23.4%, p < 0.001). Similar findings were demonstrated on ultrasound modality. A difference in performance was not evident for X-rays, CT head, and tubes/lines localization images.

Conclusions: GST were able to correctly interpret 74.2% of basic clinical images. Although superior in the evaluation of pathologies seen on CT body and ultrasound, GST have comparable performance to other trainees in X-rays, tube/line localization images, and CT head. Integration of radiology education in surgical training may enhance performance and potentially improve patient care.
