ABSTRACT
BACKGROUND: Positive communication behaviour within anaesthesia teams may decrease stress response and improve clinical performance. We aimed to evaluate the effect of positive communication during medical handover on the subsequent team-based clinical performance in a simulated critical situation. We also assessed the effect of positive communication behaviour on stress response. METHODS: This single-centre RCT involved anaesthesia teams composed of a resident and a nurse in a high-fidelity scenario of anaesthesia-related paediatric laryngospasm after a standardised handover. During the handover, similar information was provided to all teams, but positive communication behaviour was adopted only for teams in the intervention group. Primary outcome was team-based clinical performance, assessed by an independent blinded observer, using video recordings and a 0-to 100-point scenario-specific scoring tool. Three categories of tasks were considered: safety checks before the incision, diagnosis/treatment of laryngospasm, and crisis resource management/non-technical skills. Individual stress response was monitored by perceived level of stress and HR variability. RESULTS: The clinical performance of 64 anaesthesia professionals (grouped into 32 teams) was analysed. The mean (standard deviation) team-based performance score in the intervention group was 44 (10) points vs 35 (12) in the control group (difference: +8.4; CI95% [0.4-16.4]; P=0.04). The effects were homogeneous over the three categories of tasks. Perceived level of stress and HR variability were not significantly different between groups. CONCLUSIONS: Positive communication behaviour between healthcare professionals during medical handover improved team-based performance in a simulation-based critical situation.
