Electronic Dance Music events (EDMs) are complex mass gatherings and given published rates of illnesses, injuries, and hospitalizations, these events can place an additional burden on local health care services. Accordingly, during the planning process for EDMs many stakeholders are involved; however, local hospitals, a key part of the medical safety plan, are often excluded. In this case report, it is posited that the involvement of local hospital(s) and the resulting integration of on-site and acute-care service provision during an event, ultimately reduces the burden placed on local hospitals.

Case report; synthesis of published literature.

A 25,000 person per day, two-day mass gathering EDM event trialed a model of collaborative planning with a local community hospital. Planning included the identification of a hospital liaison, pre-event teleconferences between event staff, contracted and public medical response teams, emergency management teams, harm reduction practitioners, public health, and hospital personnel. Throughout the collaborative planning process, vital information was shared in order to optimize patient continuity of care and streamline the transition of care from site medical response to an acute care setting. Outcomes included the prevention of unnecessary transfers to the hospital; however, those patients who required transfer had their initial treatment started prior to leaving the venue. Further, collaborative planning also contributed to improved bidirectional data sharing to better understand the impact on the local hospital of the event, including transfers from the onsite medical team as well as transports from the community and self-presentations for care.

The collaboration of onsite medical and hospital teams improved the delivery of essential medical care to the patrons of the event and added a layer to the safety planning process essential to mass gathering events.
