Impact on emergency departments
Dr Jamie Ranse RN PhD
Research Fellow, Emergency Care
An event where a group of people come
together for a common purpose within a
particular space or venue.
Where there is the potential for a delayed
response to health emergencies due to a
number of challenges, primarily related to
the environment and patient egress.

• USA: Characteristics and resource utilization over a two year period
• 209 patients
• Present with alcohol intoxication
• Intravenous fluids and antiemetic’s
• Average length of stay of 3.3 hours
• USA: In-hospital care of adolescents and young adults who attended music concerts over a
five year period
• 142 patients
• 61% required an intervention (medications, intravenous fluids, intubation, imaging).
• Some events resulted in the activation of the hospital disaster and emergency incident

CASE: Commonwealth Games, Gold Coast 2018
Fast facts about the health service during the
• Over 440 Games-related presentations to emergency
departments at Gold Coast University Hospital and Robina
•178 inpatient admissions were Games-related
• Increase of 7% on the same period in 2017
• Gold Coast Health staff were seconded to develop and run
the polyclinic in the Athletes Village
CASE: when mass gatherings become mass casualty
• In-event health services
• Reasonable understanding
• External health services
• Some insight into the impact on ambulance services
• Some insight into the impact on hospital services
• Not comparable across events
• There is minimal research focusing on the impact of mass gatherings on health
services, such as ambulance services and hospitals
• A better understanding of this health space is required
• Collaboration between in-event and external health services
