Through its data linkage program, NCHS has been able to expand the analytic utility of the data collected from National Hospital Care Survey (NHCS) by augmenting it with mortality data from the National Death Index (NDI). Linkage of NHCS data with the NDI mortality data provides the opportunity to conduct a vast array of outcome studies designed to investigate the association of a wide variety of health factors with mortality.

Through its data linkage program, NCHS has been able to expand the analytic utility of the data collected from the National Hospital Care Survey (NHCS) by augmenting it with 2014-2018 administrative data from the Centers for Medicare & Medicaid Services’ (CMS) Medicare program. Linkage of NHCS data with the CMS Medicare Data provides the opportunity to conduct a vast array of studies on health care utilization and expenditures among the elderly U.S. population and persons receiving Medicare disability benefits.

Through its data linkage program, NCHS has been able to expand the analytic utility of the data collected from the 2014 and 2016 National Hospital Care Surveys (NHCS) by linking patient records with up to three years of administrative housing data from the U.S. Department of Housing and Urban Development’s (HUD) largest housing assistance programs: the Housing Choice Voucher (HCV) program, Public Housing (PH) , and privately owned, subsidized Multifamily housing (MF). These innovative linked data will support a wide array of patient outcomes studies, including the opportunity to study complex relationships between housing and health.

Through its data linkage program, NCHS has been able to expand the analytic utility of the data collected from the National Hospital Care Survey (NHCS) by augmenting it with administrative data from the Department of Veterans Affairs (VA). NHCS data have been linked to VA administrative data containing information on details of active-duty service in the United States uniformed services (such as branch of service and era of active-duty service) and VA benefit program utilization including VA health care, service-connected disability compensation, pension, VA guaranteed home loan program, life insurance, education, training and veteran readiness (vocational rehabilitation), and employment benefit programs.

Through its data linkage program, NCHS has been able to expand the analytic utility of the data collected from the National Hospital Care Survey (NHCS) by augmenting it with Medicaid and Children’s Health Insurance Program (CHIP) claims data collected by the Centers for Medicare & Medicaid Services (CMS) Transformed Medicaid Statistical Information System (T-MSIS). Linkage of NHCS patient data with T-MSIS enrollment and claims data creates a new data resource that can support research studies focused on a wide range of patient health outcomes and the association of means-tested government insurance programs with health and health outcomes.

NCHS has linked data from various surveys with 1999-2013 Medicare program enrollment and health care utilization and expenditure data from the Centers for Medicare & Medicaid Services (CMS). Linkage of the NCHS survey participants with the CMS Medicare data provides the opportunity to study changes in health status, health care utilization and costs, and prescription drug use among Medicare enrollees. Medicare is the federal health insurance program for people who are 65 or older, certain younger people with disabilities, and people with End-Stage Renal Disease.

This dataset includes all infant deaths that were linked to their corresponding birth certificate and includes all items released in the public-use file. Additional information in this file includes state and county of residence and exact dates of birth and death (which includes day of month, month, and year).

As a principal source of information on health care utilization in the United States, NHCS collects inpatient and emergency department data from a nationally representative sample of U.S. hospitals sourced from administrative and electronic health records data. The 2020 NHCS is conducted by the National Center for Health Statistics (NCHS) and is a member of the National Health Care Surveys – a family of surveys which measure health care utilization across a variety of health care providers and settings.
