Abstract
In a syndromic dual use application, North Carolina emergency department (ED) visits for oral health-related problems were studied using BioSense patient records stratified by age group, patient residence county, and payment method. After a case definition process using both chief complaints and diagnosis codes, the study obtained population-based visit rates and revealed age- and county-specific problems consistent over three full years ending 30Jun2011 and worsening in selected counties. The state total ED burden for oral health problems was ~2% (0.2% - 9.7% by county).
