Ambulatory Health Care Data

The National Hospital Ambulatory Medical Care Survey (NHAMCS) is designed to collect data on the utilization and provision of ambulatory care services in hospital emergency and outpatient departments and ambulatory surgery locations. Findings are based on a national sample of visits to the emergency departments,  outpatient departments, and ambulatory surgery locations of noninstitutional general and short-stay hospitals.

The National Health Care Surveys (including NAMCS, NHAMCS, and NHCS) are working with the Centers for Medicare and Medicaid Services Electronic Health Record Incentive Programs: Promoting Interoperability (PI) (formerly known as Meaningful Use (MU)) and the Merit-based Incentive Payment System (MIPS).
