Longitudinal description and evaluation of an emergency department avoidance strategy for a youth mass gathering (Schoolies) in Australia.

The IEHS, operational during Schoolies, appeared to reduce pressures on local EDs by offering rapid, targeted care for potentially vulnerable youth; decrease requirements for hospital transport and minimise impacts on care provision for the local community. Given increases in ED crowding and pressures on ambulance services, such care models may be worth considering for other types of MGEs and in other locations.
