Abstract

Researchers of complex systems argue that the growing complexity of tasks in modern systems surpasses the cognitive capabilities of individuals and teams. There is a huge gap between the tons of data being produced by systems and people’s ability to process them and arrive at the actual information that is required for their decisions. The present study suggests a theory-based approach to how a team briefing may affect the performance of teams in complex systems. Medical surgery was chosen and examined as one example of a complex process in which multidisciplinary teams are involved in a highly dynamic environment and where errors have severe consequences.

The study was conducted in two phases: first the briefing content and design were developed. This stage included interviews with team members (nurses, anesthesiologists, and surgeons) and pilot observations in operations. Then, the briefing effect was tested by comparing the frequency of Non-routine events in operations with and without a briefing. Non-routine events were deviations from good performance or 'near misses' observed in 130 operations conducted without a briefing and 102 operations conducted with a briefing.

Results showed a 25% reduction in the number of events and a 16% increase in the number of operations performed without any event. Team members who participated in briefings considered them most valuable to their own work; the team's work; and to patient safety. The teams started to perform briefings as their daily routine during the study even when the research team was absent and continue this routine to this very day.
