['To identify and describe disparities in the provision of Emergency Department (ED) care in pediatric patients presenting with chest pain (CP).', 'Nationally representative data were drawn from the National Hospital Ambulatory Medical Care Survey (NHAMCS). All ED visits with a chief complaint of CP and age <19 years from 2002 to 2006 were analyzed. The primary outcome variable was "Anytest" performed (defined as any combination of complete blood count, electrocardiogram, and/or chest x-ray). Univariable analyses were performed with "Anytest" as the dependent variable and patient characteristics as independent variables. Multivariable analysis was performed using logistic regression with the same independent patient characteristics.', 'Eight hundred eighteen pediatric CP visits representing 2 552 193 such visits nationwide were analyzed. Gender and metro/non-metro location were not associated with "Anytest." However, Caucasian patients (p = 0.01) and those with private insurance (p < 0.01) were significantly more likely to receive testing despite otherwise similar demographics and severity of illness. Multivariate analysis revealed race (p = 0.03), expected payer (p = 0.003), and triage level (p = 0.009) were significantly and independently associated with the frequency of testing performed.'] Do disparities exist in the emergency department evaluation of pediatric chest pain?
