BackgroundThis study assessed the feasibility, self-efficacy and cost of providing a high fidelity medical simulation experience in the difficult environment of an air ambulance helicopter.MethodsSeven of 12 EM residents in their first postgraduate year participated in an EMS flight simulation as the flight physician. The simulation used the Laerdal SimMan™ to present a cardiac and a trauma case in an EMS helicopter while running at flight idle. Before and after the simulation, subjects completed visual analog scales and a semi-structured interview to measure their self-efficacy, i.e. comfort with their ability to treat patients in the helicopter, and recognition of obstacles to care in the helicopter environment. After all 12 residents had completed their first non-simulated flight as the flight physician; they were surveyed about self-assessed comfort and perceived value of the simulation. Continuous data were compared between pre- and post-simulation using a paired samples t-test, and between residents participating in the simulation and those who did not using an independent samples t-test. Categorical data were compared using Fisher's exact test. Cost data for the simulation experience were estimated by the investigators.ResultsThe simulations functioned correctly 5 out of 7 times; suggesting some refinement is necessary. Cost data indicated a monetary cost of $440 and a time cost of 22 hours of skilled instructor time. The simulation and non-simulation groups were similar in their demographics and pre-hospital experiences. The simulation did not improve residents' self-assessed comfort prior to their first flight (p > 0.234), but did improve understanding of the obstacles to patient care in the helicopter (p = 0.029). Every resident undertaking the simulation agreed it was educational and it should be included in their training. Qualitative data suggested residents would benefit from high fidelity simulation in other environments, including ground transport and for running codes in hospital.ConclusionIt is feasible to provide a high fidelity medical simulation experience in the difficult environment of the air ambulance helicopter, although further experience is necessary to eliminate practical problems. Simulation improves recognition of the challenges present and provides an important opportunity for training in challenging environments. However, use of simulation technology is expensive both in terms of monetary outlay and of personnel involvement. The benefits of this technology must be weighed against the cost for each institution.

Objectives: High-fidelity medical simulation (HFMS) is increasingly utilized in resident education and evaluation. No criterion standard of assessing performance currently exists. This study compared the intermethod reliability of real-time versus videotaped evaluation of HFMS participant performance.Methods: Twenty-five emergency medicine residents and one transitional resident participated in a septic shock HFMS scenario. Four evaluators assessed the performance of participants on technical (26-item yes ⁄ no completion) and nontechnical (seven item, five-point Likert scale assessment) scorecards. Two evaluators provided assessment in real time, and two provided delayed videotape review. After 13 scenarios, evaluators crossed over and completed the scenarios in the opposite method. Real-time evaluations were completed immediately at the end of the simulation; videotape reviewers were allowed to review the scenarios with no time limit. Agreement between raters was tested using the intraclass correlation coefficient (ICC), with Cronbach's alpha used to measure consistency among items on the scores on the checklists. Conclusions: Real-time and videotaped-based evaluations of resident performance of both technical and nontechnical skills during an HFMS septic shock scenario provided equally reliable methods of assessment.ACADEMIC EMERGENCY MEDICINE 2009; 16:887-893 ª
