Surgical teams: role perspectives and role dynamics in the operating room.

Observations of surgical teams in the operating room (OR) and interviews with surgeons, circulating registered nurses (RNs), anaesthesiologists and surgical technicians reveal the importance of leadership, team member competencies and an enacted environment that encourages feelings of competence and cooperation. Surgical teams are more loosely coupled than intact and bounded. Team members tend to rely on expected role behaviours to bridge lack of familiarity. While members of the surgical team identified technical competence and preparation as critical factors affecting team performance, they had differing views over the role behaviours of other members of the surgical team that lead to surgical team performance. Observations revealed that the work climate in the OR can shape interpersonal relations and begins to be established when the room is being set up for the surgical case, and evolves as the surgical procedure progresses. The leadership and supervisory competencies of the circulating RNs establish the initial work environment. Both influenced the degree of cooperation and support that was observed, which had an effect on the interactions and relationships between other members of the surgical team. As the surgery unfolds, the surgeon's behaviours and interpersonal relations modify this environment and ultimately influence the degree of team work, team satisfaction and team performance.
