Inefficacy of simulator-based training on anaesthesiologists' non-technical skills.

BACKGROUND: Analysis of critical incidents in anaesthesia practice emphasizes the important role of non-technical skills (NTS) in improving patient safety. Therefore, debriefing with regard to NTS has been added to medical management (MM) simulator training to improve acute crisis competencies of anaesthesiologists. The purpose of this study was to compare the NTS and MM performance of two groups of anaesthesiologists in a simulated anaesthesia crisis after undergoing different types of training.

METHODS: Forty-two anaesthesiologists were randomly assigned to two different training groups, with each group participating in two simulation training sessions. One group's (NTS+MMG) training included extensive debriefing of NTS (resource management, planning, leadership and communication) and MM, while the other group (MMG) received a simpler debriefing that focused solely on MM. The quality and quantity of NTS and quality of MM performance were rated by reviewing the videotapes of the scenarios.

RESULTS: NTS+MMG did not prove superior to MMG with regard to behavioural and MM markers. The quality of NTS performances correlated significantly (P<0.01) with the quantity of NTS demonstration, and also correlated significantly with the MM actions (P<0.01) in both groups.

CONCLUSION: A single session of training including debriefing of NTS and MM did not improve the NTS performances of anaesthesiologists when compared with anaesthesiologists who only received MM training. This might indicate that a more frequent or individual training is needed to improve participants' NTS performance.
