Survey of Iowa emergency medical services on the effects of the 1993 floods.
BACKGROUND
From June through August 1993, extensive flooding in the Mississippi and Missouri River basins resulted in 50 deaths and 12 billion dollars [U.S.] in damages in nine Midwestern states. In Iowa (1990 population 2,777,000), the government declared all 99 counties Federal Disaster Areas. This study examines how this event impacted local emergency medical services (EMS).


METHODS
All 797 registered prehospital ambulance, rescue, and first-response companies in Iowa received survey questionnaires. Two follow-up mailings were provided for non-responders.


RESULTS
A total of 468 EMS companies (59%) returned completed questionnaires. The geographic distribution of responders and non-responders was similar. Of the companies responding, 132 (28%) reported an impact on their operations from the flood disaster. The most frequently reported operational changes included the use of non-traditional vehicles, providing aid to regions outside usual service areas, and involvement in non-medical rescue operations.


CONCLUSIONS
A major flood provides unique challenges for emergency medical services. Cross-sectional surveys can identify areas of improvement for prehospital systems located in flood-prone areas. Results from this study provide a basis for constructing a more refined instrument to study future flood disasters.
