Leading to recovery: Group performance and coordinative activities in medical emergency driven groups

The influence of human factors on team performance was investigated in "medical emergency driven groups" composed of medical professionals treating a sudden cardiac arrest in a high fidelity simulator setting. The group composition is unique, but realistic, in that it is not constant. Three phases are distinguished: In Phase 1, 3 nurses are present; in Phase 2, a resident joins; and in Phase 3 a senior doctor joins. It was hypothesized that directive leadership behavior would enhance group performance. This was supported with regard to the directive leadership behavior of the nurse first on bedside in Phase 1, and for directive leadership of the resident in Phase 2-but only with regard to behavior occurring in the first 30 see after entering the group, which reflects the need for quick action in this time-sensitive task. For Phase 3, we expected not only directive leadership but also indirect guidance by "structuring inquiry" of the senior doctor to enhance performance. This was confirmed for structuring inquiry. Results indicate that to enhance group performance training should go beyond "technical" training that concentrates on medical necessities. Rather, it should include aspects of group coordination, emphasizing that coordinating behavior should be adapted (a) to the situation and (b) to professional role requirements.
