ObjectiveEmergency department (ED) crowding prevents the efficient and effective use of health services and compromises quality. Patients who use the ED for nonemergent health concerns may unnecessarily crowd ED services. In this article we describe characteristics of pediatric patients in the United States who use EDs for nonemergent visits.MethodsWe analyzed data from the 2002-2005 Medical Expenditure Panel Survey. The Medical Expenditure Panel Survey is conducted by the Agency for Healthcare Research and Quality and consists of a nationally representative sample of the civilian noninstitutionalized population of the United States. Our study sample consisted of 5512 person-years of observation. We included only ED visits for children from birth to 17 years of age with a specified International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code. The main dependent variable for our multivariate logistic model was nonemergent ED use, which was constructed by using the New York University ED-classification algorithm. Independent variables were derived from Andersen's Behavioral Model of Health Services Utilization.ResultsWe found that from 2002 to 2005, a nationally representative sample of US children from birth to 17 years of age used EDs for various nonemergent or primary care-treatable diagnoses. Overall, children from higher-income families had higher ED expenditures than children from lower-income families. Children with private insurance had higher total ED expenditures than publicly insured or uninsured children, but uninsured children had the highest out-of-pocket expenditures. We found that children from birth to 2 years of age were less likely to use the ED for nonemergent diagnoses (odds ratio [OR]: 0.13; P < .01) compared with older children. Non-Hispanic black children were also less likely to use the ED for nonemergent diagnoses (OR: 0.40; P = .03) than were non-Hispanic white children.ConclusionChildren's sociodemographic characteristics were predictors of nonemergent use of ED services.
