Minen MT, et al. - Researchers aimed at assessing the frequency of headache revisits among patients who present to an Emergency Department (ED) for management of migraine and sociodemographic factors associated with the revisit. Using the New York City Department of Health and Mental Hygiene Syndromic Surveillance database, it was noted that more than a quarter of initial ED visits for migraine are followed by headache revisits in <6 months. Of the revisits for headache, 9% occur within 72 hours and 46% occur within 90 days of the initial migraine visit. No association of sex, age, and poverty level with an ED revisit was noted.
