Based on findings that clear, directive leadership can enhance performance in cardiac resuscitation [5,8], we further (5) investigated if stress was associated with fewer leadership statements. Methods Participants and simulator This study was conducted at the Simulator Center of the University Hospital in Basel, Switzerland, between December, 2007 and May, 2008. Workshops were offered to 4th year medical students and presented as a learning experience in a patient simulator. Prior to this simulation, no CPR training had been offered to the students within their

medical curriculum. No information about the content of the scenarios and about our specific hypotheses Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical was provided to students before the study (blinding). The study was done in compliance with the Helsinki Declaration, approved by the local ethical committee (Ethikkommission beider Basel, EKBB, http://www.ekbb.ch/), and written informed consent was obtained from all participants. For this study, we used a high fidelity manikin with the possibility of remote control of vital signs (Human Patient Simulator, METI) [36,37]. This full body simulator is a computer-based manikin with human physiology emulation capability that

also can interact very realistically, e.g. by talking. Study design and intervention This is a prospective randomized controlled study. Prior to the test-scenario, Inhibitors,research,lifescience,medical all students were made familiar with the simulator in a baseline training session followed by a general video-assisted debriefing focusing on ACLS algorithms (Figure 1). Students were then randomly allocated to two different Inhibitors,research,lifescience,medical randomization arms using computer generated randomization lists. Students in the control group did not receive any further instructions. Students in the intervention group received a 10 minute instruction to cope Inhibitors,research,lifescience,medical with stress. They were informed that an emergency situation is a stressful experience for health care workers and that perceived

stress may interfere with their decision-making abilities and performance. Particularly, feeling overwhelmed by stress may cause cognitive impairment potentially leading to loss of concept how to deal Megestrol Acetate with an emergency situation, which in turn further increases stress (vicious cycle). However, it is possible to overcome this situation by focusing on the basic conditions of the situation and the selleck immediate actions that are needed. They were instructed that they should ask two task-focusing questions aloud (“what is the patient’s condition?”, “what immediate action is needed?”) to overcome the negative consequences of feeling overwhelmed by stress.
