National Hospital Ambulatory Medical Care Survey

The National Hospital Ambulatory Medical Care Survey (NHAMCS) is a federal program that collects data on visits to hospital outpatient clinics and emergency departments across the United States. It gathers information about patient demographics, reasons for visits, diagnoses, tests, treatments, and outcomes. This data helps health officials, researchers, and policymakers understand patterns in emergency and outpatient care, assess healthcare quality, and plan resources. The survey provides a valuable snapshot of how hospitals serve patients, supporting efforts to improve healthcare accessibility and effectiveness nationwide.
