  • Description:
    This brochure lists all publicly available data items for the National Ambulatory Medical Care Survey (NAMCS) and the National Hospital Ambulatory Medical Care Survey (NHAMCS), arranged by ambulatory care setting and year. NAMCS and NHAMCS are conducted by the Centers for Disease Control and Prevention’s National Center for Health Statistics (NCHS), within NCHS’ Division of Health Care Statistics. The surveys are components of the National Health Care Surveys, a family of surveys that measure health care utilization across various settings, including physician offices, community health centers, hospital emergency departments (EDs), outpatient departments (OPDs), and ambulatory surgery locations. The lists provided here show which variables were used in each survey year and how they have changed, or remained the same, over time. Ambulatory medical care is the predominant method of providing health care services in the United States, and although it occurs in a wide range of settings, the largest proportion of ambulatory care takes place in physician offices. NAMCS was inaugurated in 1973 to gather, analyze, and disseminate information about the health care provided by office-based physicians. NAMCS is complemented by NHAMCS, which was first conducted in 1992 to expand the scope of data collection to the medical services provided in EDs, OPDs, and ambulatory surgery locations (both hospital-based and freestanding). Hospital-based ambulatory surgery locations were added to NHAMCS in 2009, and freestanding centers were added in 2010. Together, NAMCS and NHAMCS data provide an important tool for tracking ambulatory health care utilization in the United States.
