Major Incident Hospital Simulations in Hospital Based Health Care: A Scoping Review.

Major incidents are occurring in increasing frequency, and place significant stress on existing health-care systems. Simulation is often used to evaluate and improve the capacity of health systems to respond to these incidents, although this is difficult to evaluate. A scoping review was performed, searching 2 databases (PubMed, CINAHL) following PRISMA guidelines. The eligibility criteria included studies addressing whole hospital simulation, published in English after 2000, and interventional or observational research. Exclusion criteria included studies limited to single departments or prehospital conditions, pure computer modelling and dissimilar health systems to Australia. After exclusions, 11 relevant studies were included. These studies assessed various types of simulation, from tabletop exercises to multihospital events, with various outcome measures. The studies were highly heterogenous and assessed as representing variable levels of evidence. In general, all articles had positive conclusions with respect to the use of major incidence simulations. Several benefits were identified, and areas of improvement for the future were highlighted. Benefits included improved understanding of existing Major Incident Response Plans and familiarity with the necessary paradigm shifts of resource management in such events. However, overall this scoping review was unable to make definitive conclusions due to a low level of evidence and lack of validated evaluation.
