NCHS Data Linkage

Linkages with the National Hospital Care Survey Data

NCHS has conducted linkages with the National Hospital Care Survey (NHCS) data and mortality information from the National Death Index (NDI) and Medicare enrollment and claims data from the Centers for Medicare & Medicaid Services (CMS). NHCS is designed to provide accurate and reliable health care statistics that answer key questions of interest to health care and public health professionals, researchers, and health care policy makers. The linked data expand the analytic utility of the data collected from NHCS and provide the opportunity to conduct a vast array of studies focused on the associations between a variety of health factors, health care utilization and mortality.

The linked datasets were created with support from the Office of the Secretary Patient Centered Outcomes Research Trust Fund (OS-PCORTF).
