On September 18, 2003, Hurricane Isabel made landfall as a category 2 hurricane over the mid-Atlantic region, generating record conditions for the region's 27 years of monitoring. The purpose of this study was to investigate the impact of the hurricane on the number and type of emergency department (ED) patient visits and its impact on hospital admission rate from the day of landfall to day 5 postlandfall. Comparisons were made with a control group, which comprised average daily ED census during the six-month period preceding landfall and the average daily admission rates for the preceding six months. ⋯ A significant overall reduction in ED visits by almost half the typical average volume was noted on the day of landfall (-46%). During the four days immediately following landfall, however, there was a marked increase in the overall ED census, with a particularly high increase on day 1 postlandfall. The largest complaint category increase was minor trauma (+57%). Hospital admission rates were highest on the day of landfall and seemed to return to baseline on day 1 postlandfall. These data may be useful for structuring ED personnel and hospital resource allocation to better serve its community during hurricane preparedness planning.
