Does the unexpected death of the manikin in a simulation maintain the participants’ perceived self-efficacy? An observational prospective study with medical students

Abstract

Abstract Background The death of a simulated patient is controversial. Some educators feel that having a manikin die is prejudicial to learning; others feel it is a way of better preparing students for these situations. Perceived self-efficacy (PSE) reflects a person’s perception of their ability to carry out a task. A high PSE is necessary to manage a task efficiently. In this study, we measured the impact of the death of a simulated patient on medical students’ perceived self-efficacy concerning their ability to cope with a situation of cardiac arrest. Methods We carried out a single-centre, observational, prospective study. In group 1 (n = 27), pre-graduate medical students were warned of the possible death of the manikin; group 2 students were not warned (n = 29). The students’ PSE was measured at the end of the simulated situation and after the debriefing. Results The PSE of the two groups was similar before the debriefing (p = 0.41). It had significantly progressed at the end of the debriefing (p < 0,001). No significant difference was noted between the 2 groups (p = 0.382). Conclusions The simulated death of the manikin did not have a negative impact on the students’ PSE, whether or not they had been warned of the possible occurrence of such an event. Our study helps defend the position which supports the inclusion of unexpected death of the manikin in a simulation setting.
