Use of an Observer Tool to Enhance Observers' Learning of Anesthesia Residents During High-Fidelity Simulation: A Randomized Controlled Trial.

INTRODUCTION: The growing number of learners implies that all of them cannot play an active role during high-fidelity scenarios. Studies suggest a positive educational value when learners are observers only, but it remains uncertain whether learning outcomes might be improved by using an observer tool (OT). METHODS: Eighty-nine anesthesia residents were randomized to use an OT (n = 44, OT+; based on a cognitive aid) or not (n = 45, OT-) when not role-playing. The main outcome parameter was the learning outcomes assessed by comparing the change (before-after) in the response score to a questionnaire dedicated to medical knowledge obtained in the OT+ and OT- groups. The impact of using the OT was also assessed by measuring the perceived stress level and the change of the Anesthetists' Non-Technical Skill items values. RESULTS: At the end of the session, the mean medical knowledge score (mean ± SD) was higher in the OT+ group than in the OT- group (11.4 ± 2.7 vs. 9.6 ± 2.4, respectively, P = 0.0008). The mean Anesthetists' Non-Technical Skill score and level of stress perceived did not differ between groups. Trainees rated similarly the learning value and satisfaction related to the simulation course. CONCLUSIONS: This study suggests that observing high-fidelity simulation scenarios using an OT based on a cognitive aid increases the medical knowledge gain when compared with that seen in passive observers. This study suggests that the use of an OT improves the educational value of simulation.

External Cardiac Massage Training of Medical Students: A Randomized Comparison of Two Feedback Methods to Standard Training.

BACKGROUND: The most recent recommendations support learning of external cardiac massage (ECM) through feedback devices. OBJECTIVES: The objective was to compare the effects on immediate and 3-month retention of ECM technical skills when using feedback devices compared with training without feedback as part of a half-day training session in medical students. METHODS: This randomized study was performed using the Resusci Anne QCPR manikin in 64 medical students. We compared the quality of ECM with nonfeedback training in the control group (group 1) vs. 2 feedback learning methods (group 2, PocketCPR and group 3, Skill Reporter each used with visual display available to the trainee). At the end of the training session and 3 months later, students performed chest compressions blindly during a 2-min assessment session. The median compression score was the primary outcome for assessing immediate and long-term retention. RESULTS: Regarding immediate retention, the median compression score was significantly lower in group 1 (23%) than in groups 2 (81%) and 3 (72%) (p < 0.05) with no difference between the 2 feedback methods. At 3 months, mean compression scores remained high but not significantly different between the 2 feedback groups. CONCLUSION: The use of a feedback device used for ECM training improves the quality of immediate retention of technical ECM skills compared with traditional teaching in medical students. At 3 months, the 2 groups with feedback retained a high level of performance. No significant difference could be demonstrated between the 2 feedback methods.
