Background
A resident working under the entrustable professional activity of a graduated independent coverage model must identify nonaccidental trauma and notify clinicians of this concern to facilitate potential removal of the child from harm. The resident’s role in identifying child abuse has not previously been studied.
Objective
The purpose of this study was to assess radiology residents’ ability to identify radiographic imaging findings of nonaccidental trauma in a simulated call environment.
Materials and methods
The Wisdom in Diagnostic Imaging Emergent/Critical Care Radiology Simulation (WIDI SIM) is a strategically designed computer-aided simulation of an emergency imaging experience that has been rigorously tested and proven to be a reliable means for assessing resident preparedness to competently and independently cover radiology call. The residents are provided with 65 cases of varying difficulty, including normal studies. Those cases include ones that require the resident to accurately identify skeletal findings of nonaccidental trauma. The residents respond using free text that is then scored manually by faculty members utilizing a robust grading rubric. Missed cases are then categorized by observation error and/or interpretative errors.
Results
A total of 675 radiology residents were given a case of nonaccidental trauma using the WIDI simulation web-based test platform between 2014 and 2017. Child abuse was consistently underdiagnosed by radiology residents being tested for call readiness irrespective of the numbers of years in training. Correct diagnostic score averages per year ranged from 10% to 79%. In year 1, 71% of residents correctly diagnosed nonaccidental trauma with a total of 101 participants. In year 2, 130 residents participated with only 20% answering correctly. In year 3, there were 201 participants with 79% correctly diagnosing nonaccidental trauma. In year 4, only 10% of 243 residents accurately diagnosed nonaccidental trauma. Residents from various stages of training were tested. Cases used with leading histories provided, accounted for a higher correct call rate.
Conclusion
Radiology residency programs may be deficient in teaching residents to accurately recognize and report child abuse. This deficiency has potential implications for programs where a radiology attending is not present after hours as it raises the concern that child abuse may be missed by residents taking independent call. These data further question whether graduating radiologists are competent to recognize nonaccidental trauma and demonstrates the need for additional mandatory training during radiology residency.
