Abstract:

The National Center for Health Statistics (NCHS) conducts the National Hospital Ambulatory Medical Care Survey (NHAMCS) to measure utilization of ambulatory medical care service provided in non-Federal, non-institutional general and short-stay hospitals located in the 50 states and the District of Columbia. From its beginning in 1991, NHAMCS has collected data about sample visits made to hospital emergency and outpatient departments. In 2009, the survey also began collecting data about visits made for ambulatory surgery. In 2010, the survey universe was further expanded to include visits made to freestanding (not-hospital based) ambulatory surgery centers. This paper discusses the sampling design for the current survey.
