Impact sur l’apprentissage des compétences techniques de l’utilisation d’une grille d’observation chez des internes d’anesthésie-réanimation observateurs en séance de simulation : étude randomisée

Abstract : Introduction: the increasing use of high-fidelity simulation is limited by the imbalance between the growing number of students and the human resources available in such a way that all residents cannot play a role during scenarios. For those who are role-playing, experiential learning improves knowledge and competences. Studies suggest a positive educational value when learners are observers only, but several studies suggest that learning outcomes might be improved by using an observer tool. This study aims at measuring the impact of an observer tool on trainees’ technical skills. Methods: in this study performed in the Simulation center (LabForSIMS) of the Paris Sud Medical School, 89 anesthesia residents (3rd or 4th year) were included and randomized to use an observer tool (n = 44, OT +) or not (n = 45, OT-) when not being 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 the knowledge of technical skills obtained by those in the OT+ and OT- groups. The impact of using the observer tool was also assessed by measuring the stress level and the perception of change of the anaesthetists’ non-technical skills (ANTS) items values. Results: all questionnaires could be analyzed. The mean technical skills score [m ± 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 ANTS score of at the end of session was 29.3 ± 3.9 in the OT- group versus 29.1 ± 4.6 in the OT+ group (p = 0.8). Stress perceived did not differ between the two groups [group OT-: 6.6 ± 2.1 vs group OT+: 6.7 ± 2.1, p = 0.9]. When trainees rated the learning value and satisfaction related to the simulation course, there was no difference among groups. Conclusion: this study suggests that observing immersive scenarios of high fidelity simulation using an observer tool increases the medical knowledge gain when compared to the gain seen in passive observers. This study suggests that the use of an observer tool improves the educational value for trainees. Additional studies are needed to assess if a similar benefit would occur by using an observer tool dedicated to non-technical skills.
