With the move into Gold Coast University Hospital, a new disaster plan was developed in 2017. To assess preparedness for the Commonwealth Games (April 2018), a number of mass casualty exercises were conducted, including a large multi-agency exercise with Queensland Police and Ambulance Services. During this preparation phase, senior clinicians from the perioperative area clarified their sub-plans and developed a novel model of periop response.

This study assesses this model of response and evaluates it within the context of periop disaster exercises.

The periop response model evolved through multi-disciplinary key stakeholder engagement into a defined model of surgical, anesthetic, and periop nursing responses with dedicated roles and parallel communication streams from ED to OR by the respective specialties. Throughout different disaster exercises, this model of response was tested, refined, and evaluated by formal post-exercise debriefs and group meetings.

Since May 2017, seven different mass casualty exercises with periop response were performed; firstly, a table-top (EmergoTrainSystem) format was used, which revealed communication and logistical deficiencies. After model refinement, further exercises were accomplished, all within the clinical environment, including movements of mock patients from ED to OR. These exercises generated improvements in communication, coordination, and logistics. Every exercise was also used to test more detailed information, communication, and organizational tasks of the various involved craft groups, such as notification, call-in lists, whiteboard structure, transport facilitation, and many more. Overall, our newly developed periop response model proved to be robust and successful, even with rotating personnel through different roles.

Apart from the success of the periop response model, other hospital areas (ICU, bed and ward management) became involved. With growing interest and staff turn-over a regular periop disaster response exercise program has now been established. This model of periop response has potential for use in other health systems.
