Study objective We identify frequent users of the emergency department (ED) and determine the characteristics of these patients. Methods Using the 2000 to 2001 population-based, nationally representative Community Tracking Study Household Survey, we determined the number of adults (aged 18 and older) making 1 to 7 or more ED visits and the number of visits for which they accounted. Based on the distribution of visits, we established a definition for frequent user of 4 or more visits. Multivariat...
