(P2-43) Utilizing a Unified Health Command Structure for Mass Gathering Preparedness and Response: Lessons Learned from the 2008 Pacific Arts Festival

Abstract

Background

The Pacific Arts Festival is a mass-gathering event occurring every four years in Oceania. The 10th festival in American Samoa, July 20 to August 2, 2008, brought 2200 performers and 2500 tourists (a 15% population increase) from 27 Pacific nations to the island. Anticipated healthcare concerns included hospital surge (175% in 2004), HIV/STI transmission, imported/communicable diseases, food/water/sanitation-borne illness, interpersonal violence, and healthcare resource utilization.

Objective

To describe the preparedness and response efforts for this mass gathering event by emergency medical services, the hospital, and the department of health.

Methods

A retrospective review of after-action reports, public health and emergency department surveillance records, and key-informant interviews was conducted. Descriptive statistics were used to evaluate data.

Results

A Unified Command structure was utilized for pre-/post-event response. Patient surveillance data was collected daily. During the festival 217 participants (42% female, 58% male, Average age 36) sought medical care. Acute illness (n = 166), injury (n = 39), other (n = 15), routine follow up (n = 9), chronic conditions (n = 6), mental health (n = 1), OB/GYN (n = 1) were complaints addressed. Predominant acute illnesses included headache (n = 49, 23%), respiratory illness (n = 30, 14%), musculoskeletal pain (n = 26, 12%), and gastroenteritis (n = 17, 8%). One fatality occurred among delegates. No public health outbreaks were reported. Visits per healthcare venue demonstrated a decentralization of patient surge from the hospital setting (37.4% venue aid stations, 28.1% delegation medical staff, 24% DOH clinic, 10.6% hospital).

Conclusion

A unified health command structure was effective in responding to this mass gathering event. Surveillance data was rapidly gathered and utilized to direct healthcare resources. Efforts to decentralize healthcare from the hospital were successful. Public health emergencies were avoided.
