Brief reportChronic Disease and Disasters: Medication Demands of Hurricane Katrina Evacuees
Introduction
On August 29, 2005, Hurricane Katrina struck the Gulf Coast, forcing the relocation of more than 18,000 Louisiana and Mississippi residents into mass evacuee centers in San Antonio, TX. Disaster-related morbidity from acute traumatic injuries, environmental exposures, and infectious diseases was expected, and medical relief plans focused on these well-recognized consequences of natural disasters.1 Although survivor needs are likely incident specific, recent evidence suggests that post-disaster medical care often involves few patients with acute conditions2, 3 and many patients with low-acuity complaints.4, 5, 6
In this report, disease surveillance and pharmaceutical use data from a group of displaced Hurricane Katrina survivors are presented. These data describe the survivors’ medication requirements and the extent to which these needs were met by federal disaster relief teams and local retail pharmacies.

Methods
The primary outcomes of interest for this ecological study were medications dispensed to Hurricane Katrina evacuees residing in a San Antonio evacuee center from September 2nd through the 21st, 2005. During this period, the Centers for Disease Control and Prevention assisted the San Antonio Metropolitan Health District with disease surveillance in four primary evacuee centers. Health care was provided to evacuees in one evacuee center by the Texas-1 and Florida-2 disaster medical assistance
Results
Daily evacuee census ranged from 2020 to 6219 people (median = 3707). The median number of healthcare encounters per day was 218 (5% of evacuee population), with a range of 5 to 574 encounters (<1% to 13% of evacuee population). Of 5030 evacuee healthcare encounters captured by the syndromic surveillance system, 4229 (84%) were categorized;b 2834 (67%) were for acute care conditions, 634 (15%) were explicitly for care of chronic medical conditions, and 761 (18%) were for routine care, including
Conclusion
Hurricane evacuees in San Antonio relied on retail pharmacies to meet the majority of their medication needs. Although evacuees seeking care for chronic medical complaints accounted for relatively few healthcare encounters (15%), their medication needs constituted 68% of all DDDs dispensed. The DMATs deployed to San Antonio appeared better equipped to meet the acute care medication needs of evacuees than their chronic medication demands. The DMAT pharmacy dispensed fewer doses per prescription

Other problems with access to medications during a disaster include not having a prescription to refill at a pharmacy in a non-affected area or being unable to recall what drugs and/or dosages were prescribed to access them from another source.
