The NHCS is an integrated program of health care provider and establishment surveys and inventories conducted by the National Center for Health Statistics to provide national data on the provision and utilization of health care resources for the major sectors of the health care delivery system. These data are used to monitor health care use, the impact of medical technology, and the quality of care provided to the US population. Currently active NHCS components include the following national probability surveys: the National Hospital Discharge Survey (NHDS), the National Survey of Ambulatory Surgery (NSAS), the National Ambulatory Medical Care Survey (NAMCS), the National Home and Hospice Care Survey (NHHCS), and the National Nursing Home Survey (NNHS).
HIV data needs are addressed through each of the NHCS components through the collection and provision of diagnostic and other information related to HIV. These data describe the utilization of the major sectors in the health care delivery system and the impact of treating HIV on the health system. Specifically, NHDS reports have been published addressing trends in hospital use for HIV. The NAMCS and the NHAMCS provide data on visits to physicians’ offices, and hospital emergency and outpatient departments, respectively, and also collect data on visits at which HIV serology tests were ordered or provided. The NHHCS provides data on the patients receiving care and services received from home health agencies and hospices.
