Optimal emergency personnel allocation after a natural disaster

Area of Science:

• Disaster medicine
• Emergency medical services research
• Public health preparedness

Background:

• Limited research exists on the impact of natural disasters on Emergency Medical Services (EMS) utilization and public awareness.
• Understanding emergency call patterns post-hurricane is vital for optimizing response and public health strategies.

Purpose of the Study:

• To analyze emergency call types and distribution following South Florida hurricanes in 2005.
• To identify key areas for public health education and EMS training to mitigate disaster impact.

Main Methods:

• Retrospective review of 911 calls to Miami-Dade Fire Rescue (MDFR) dispatch.
• Data collected for the 3 days preceding and following Category 3 or higher hurricanes (Katrina, Rita, Wilma) in 2005.

Main Results:

• Hurricanes Katrina and Wilma significantly increased daily 911 calls compared to pre-storm levels.
• Katrina and Wilma led to statistically significant increases in calls for breathing emergencies, convulsions/seizures, and hazardous situations.
• Hurricane Rita showed a significant increase in calls for convulsions and seizures.

Conclusions:

• Hurricane events are associated with a notable rise in 911 calls for respiratory issues, seizures, and hazardous situations.
• Targeted public health education, strategic EMS resource allocation, and adapted triage protocols can reduce strain on emergency services and improve outcomes after disasters.
