Objectives: This study assessed whether sociodemographic differences exist in triage assignment and whether these differences affect initial diagnostic testing in the emergency department (ED) for patients presenting with chest pain.
Methods: A nationally representative ED data sample for all adults (>or=18 years) was obtained from the National Hospital Ambulatory Health Care Survey of EDs for 1997-2006. Weighted logistic regression was used to examine the associations between race and presenting symptom, triage assignment, and test ordering, adjusting for patient and hospital characteristics.
Results: Over 10 years, an estimated 78 million visits to the ED presented with a complaint of chest pain. Of those presenting with chest pain, African Americans (odds ratio [OR] = 0.70; 99% confidence interval [CI] = 0.53 to 0.92), Hispanics (OR = 0.74; 99% CI = 0.51 to 0.99), Medicaid patients (OR = 0.72; 99% CI = 0.54 to 0.94), and uninsured patients (OR = 0.65; 99% CI = 0.51 to 0.84) were less likely to be triaged emergently. African Americans (OR = 0.86; 99% CI = 0.70 to 0.99), Medicaid patients (OR = 0.70; 99% CI = 0.55 to 0.88), and uninsured patients (OR = 0.70; 99% CI = 0.55 to 0.89) were less likely to have an electrocardiogram (ECG) ordered. African Americans (OR = 0.69; 99% CI = 0.49 to 0.97), Medicaid patients (OR = 0.67; 99% CI = 0.47 to 0.95), and uninsured patients (OR = 0.66; 99% CI = 0.44 to 0.96) were less likely to have cardiac enzymes ordered. Similarly, African Americans and Hispanics were less likely to have a cardiac monitor and pulse oximetry ordered, and Medicaid and uninsured patients were less likely to have a cardiac monitor ordered.
Conclusions: Persistent racial, sex, and insurance differences in triage categorization and basic cardiac testing exist. Eliminating triage disparities may affect "downstream" clinical care and help eliminate observed disparities in cardiac outcomes.
