How to improve quality of care in overcrowded emergency departments?
Development and evaluation of a virtual research environment. (Preprint)
BACKGROUND Despite wide literature on ED overcrowding, scientific knowledge on emergency physicians’ cognitive processes coping with overcrowding is limited. OBJECTIVE We sought to develop and evaluate a virtual research environment that will allow us to study the effect of physicians’ strategies and behaviours on quality of care in the context of emergency department overcrowding. METHODS A simulation-based observational study was conducted over two stages: the development of a simulation model and its evaluation. A research environment in Emergency Medicine combining virtual reality and simulated patients has been designed and developed. Then, twelve emergency physicians took part in simulation scenarios and had to manage thirteen patients during a 2-hour period. The study outcome was the authenticity of the environment through realism, consistency and mastering. The realism was the resemblance perceived by the participants between virtual and real Emergency Department. The consistency of the scenario and the participants’ mastering of the environment was expected for 90% of the participants. RESULTS The virtual emergency department was considered realistic with no significant difference from the real world concerning facilities and resources except for the length of time of procedures that was perceived to be shorter. 100% of participants deemed that patient information, decision-making and managing patient flow were similar to real clinical practice. The virtual environment was well-mastered by all participants over the course of the scenarios. CONCLUSIONS The new simulation tool, Virtual Research Environment in Emergency Medicine has been successfully designed and developed. It has been assessed as perfectly authentic by emergency physicians compared to real EDs and thus offers another way to study human factors, quality of care and patient safety in the context of ED overcrowding.
