Asthma is a prevalent, morbid, and costly chronic condition that may result in preventable exacerbations requiring emergency department (ED) care. In North Carolina we have limited information about the frequency and characteristics of asthma-related ED visits. ⋯ We have characterized the burden of asthma in EDs across North Carolina, by county and among key subpopulations. These data can be used to target and evaluate local and statewide asthma-control policy efforts.
