Getting better all the time? Facilitating accurate team self-assessments through simulation

Introduction Our study explores the extent to which teams are accurate assessors of their own performance and teamwork, and how simulation can help this critical skill develop over time. Methods Surgery residents in teams of three completed five daily simulations. After each scenario, each team reviewed their performance and jointly completed a scenario-specific team performance evaluation and a 17-item Communication and Teamwork Skills tool. Videos were rated to obtain discrepancy values. Paired-samples t-tests and mean comparisons were used to examine changes in team self-assessment accuracy and comparisons between high-performing and low-performing teams. Results Resident (n=30) teams rated team performance higher than faculty across the first 3 days (p<0.01), but provided similar ratings thereafter. Agreement of team performance from day 1 to 5 significantly improved (p<0.001). Teams rated their teamwork higher than faculty across all days (p<0.01). Top performing teams provided more accurate self-assessments for both teamwork (average discrepancy 8% vs 39%) and team performance (average discrepancy 12% vs 23%). Conclusion Teams that continue to work together over time may become more accurate judges of their own performance, but do not become more accurate assessors of teamwork competencies.
