BackgroundThe existence of race and gender differences in the provision of cardiovascular health care has been increasingly recognized. However, few studies have examined whether these differences exist in the emergency department (ED) setting.ObjectivesTo evaluate race, gender, and insurance differences in the receipt of early, noninvasive diagnostic tests among persons presenting to an ED with a complaint of chest pain.MethodsData were drawn from the U.S. National Hospital Ambulatory Health Care Survey of EDs. Visits made during 1995-2000 by persons aged 30 years or older with chest pain as a reason for the visit were included. Factors affecting the likelihood of ordering electrocardiography, cardiac monitoring, oxygen saturation measurement using pulse oximetry, and chest radiography were analyzed using multivariate probit analysis.ResultsA total of 7,068 persons aged 30 years or older presented to an ED with a primary complaint of chest pain during the six-year period, corresponding to more than 32 million such visits nationally. The adjusted probability of ordering a test was highest for non-African American patients for all tests considered. African American men had the lowest probabilities (74.3% and 62% for electrocardiography and chest radiography, respectively), compared with 81.1% and 70.3%, respectively, among non-African American men. Only 37.5% of African American women received cardiac monitoring, compared with 54.5% of non-African American men. Similarly, African American women were significantly less likely than non-African American men to have their oxygen saturation measured. Patients who were uninsured or self-pay, as well as patients with "other" insurance, also had a lower probability than insured persons of having these tests ordered.ConclusionsThis study documents race, gender, and insurance differences in the provision of electrocardiography and chest radiography testing as well as cardiac rhythm and oxygen saturation monitoring in patients presenting with chest pain. These observed differences should catalyze further study into the underlying causes of disparities in cardiac care at an earlier point of patient contact with the health care system.
