Purpose: The aim of this study was to assess the perceived value and impact of a hands-on mock call simulation program on resident confidence with interpretation of emergency department overnight call cases.
Methods: A five-session course was implemented in June of 2018 for rising PGY-3/R2 residents to mimic the experience of overnight call with indirect supervision. Sessions were led by senior residents in the program and consisted of timed, independent interpretation of 15-20 high-yield cases per day which highlighted "do-not miss" critical findings and simulated workflow interruptions including phone calls, consultations, and questions from technologists. IRB-approved, and anonymous pre- and post-course surveys were administered to participants which assessed residents' degree of confidence in interpretation of on-call cases and comparison of the mock call experience with existing preparatory strategies. Survey responses were analyzed using McNemar's test and Mann-Whitney U test.
Results: Our survey response rate was 91% (29/32). After completing the mock call simulation, there was a significant increase in the mean Likert score of resident confidence levels and feelings of preparedness from 4.59 to 7.38 (p < 0.01). The majority of respondents (72.4% [21/29]) felt that the mock call simulation was "extremely useful." One hundred percent of respondents indicated that the mock call simulation should be implemented for the following year.
Conclusion: Implementation of a hands-on mock call simulation significantly improves the confidence levels of radiology residents before assuming on-call responsibilities and may serve as an adjunct to existing preparatory strategies.
