NCHS Data Linkage

Restricted-Use Linked NHCS-CMS Medicare Data

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 CMS Medicare Master Beneficiary Summary File (MBSF). Linkage of NHCS data with the CMS Medicare MBSF provides the opportunity to conduct a vast array of utilization studies on the Medicare-eligible population.


Data Access

Due to confidentiality requirements, the Restricted-use linked NHCS-CMS MBSF data are accessible only through the NCHS Research Data Center (RDC) Network. All interested researchers must submit a research proposal to the RDC. Please see the RDC website for instructions on submitting a proposal.
