Objective Workplace-based assessment (WBA) plays a crucial role in assessing entrustable professional activities (EPAs) in the competency-based medical education era. This pilot study explored the perceptions of residents and assessors of two WBAs for three Korean Society of Emergency Medicine EPAs.
Methods Eight emergency medicine (EM) residents underwent WBAs, with mini-clinical evaluation exercises (mini-CEX) conducted by nine EM faculty members and multisource feedback (MSF) provided by two internal medicine faculty members and four emergency room nurses, for a total of 69 assessments. We conducted an anonymous online survey to gather feedback on experiences, perceptions, and recommendations for improving WBA, such as mini-CEX and MSF, with responses scored on a 5-point Likert scale.
Results Of the 23 initial participants, 15 (65.2%) responded, including 5 residents and 10 assessors. EM faculty viewed mini-CEX favorably, noting its strong integration of supervision and effectiveness in assessing resident performance. EM residents reported comfort issues during assessments, preferring immediate feedback and multiple assessors. MSF was generally perceived positively but showed discrepancies in the utilities of rating scales and feedback types, indicating potential areas for improvement.
Conclusion Two WBAs for three Korean Society of Emergency Medicine EPAs were found to be feasible and acceptable in the context of Korean EM residency training. However, perceptions varied between assessors and residents, necessitating clear communication about WBA objectives and processes. Our findings are useful for shaping future EPA-based training programs, balancing traditional and WBA methods, and enhancing feedback quality.

Objective Our aim was to compare the compression quality, exercise intensity, and energy expenditure in 5-minute single-rescuer cardiopulmonary resuscitation (CPR) using 15:1 or 30:2 compression-to-ventilation (C:V) ratios or chest compression only (CCO).
Methods This was a randomized, crossover manikin study. Medical students were randomized to perform either type of CPR and do the others with intervals of at least 1 day. We measured compression quality, ratings of perceived exertion (RPE) score, heart rate, maximal oxygen uptake, and energy expenditure during CPR.
Results Forty-seven students were recruited. Mean compression rates did not differ between the 3 groups. However, the mean percentage of adequate compressions in the CCO group was significantly lower than that of the 15:1 or 30:2 group (31.2±30.3% vs. 55.1±37.5% vs. 54.0±36.9%, respectively; P<0.001) and the difference occurred within the first minute. The RPE score in each minute and heart rate change in the CCO group was significantly higher than those of the C:V ratio groups. There was no significant difference in maximal oxygen uptake between the 3 groups. Energy expenditure in the CCO group was relatively lower than that of the 2 C:V ratio groups.
Conclusion CPR using a 15:1 C:V ratio may provide a compression quality and exercise intensity comparable to those obtained using a 30:2 C:V ratio. An earlier decrease in compression quality and increase in RPE and heart rate could be produced by CCO CPR compared with 15:1 or 30:2 C:V ratios with relatively lower oxygen uptake and energy expenditure.
