Master's thesis in Health and social sciencesThe provision of life aid support to critically ill and injured patients in helicopter emergency medical sevices (HEMS) is a complex process strogly dependent on the team’s non-technical skills to provide sufficient health care.These skills include task management, situation awareness, decisionmaking and teamwork. However there has been a lack of frameworks for measuring such non-technical skills for air amulance personell. In 2015 Julia Myers performed a cuztomisation of the former validated observation tool Aneasthetists Non Technical Skills (ANTS) for use in HEMS called AeroNOTS (aeromedical non- technical skills). In the present study we apply this tool in a simulated clinical setting in Norway, to explore whether the tool is applicable in our environment,assess the tool’s validity, and measure whether NTS improve according to physicians’ experience.Stiftelsen Norsk Luftambulans
