Debriefing decreases mental workload in surgical crisis: A randomized controlled trial

Area of Science:

• Medical Education
• Surgical Simulation
• Human Factors Engineering

Background:

• Mental workload, the cognitive effort for tasks, can increase during crises.
• Elevated mental workload negatively impacts performance and patient safety.
• This study investigates interventions to manage mental workload in surgical training.

Purpose of the Study:

• To measure the impact of debriefing on surgical trainees' mental workload.
• To assess the effect of a systematic crisis approach on cognitive load.
• To evaluate performance changes related to mental workload in simulated surgical crises.

Main Methods:

• Twenty junior surgical residents underwent simulated postoperative crises.
• Participants were randomized into a debriefing with feedback group or a control group.
• Mental workload was measured using a wireless vibrotactile device assessing response times.

Main Results:

• The debriefing group showed a significant reduction in mental workload (median response time decrease of -695 ms).
• The control group experienced an increase in mental workload (median response time increase of 42 ms).
• The difference in mental workload reduction between groups was statistically significant (P=0.049).

Conclusions:

• Debriefing after simulated surgical crises may decrease trainee mental workload.
• Reduced mental workload can potentially enhance operative performance and patient safety.
• This highlights the value of structured debriefing in surgical education.
