NCHS Data Linkage Activities NCHS has developed a record linkage program designed to maximize the scientific value of the Center's cross-sectional surveys. Linked data files enable researchers to examine the factors that influence disabilities, diseases, health care utilization, morbidity, and mortality. NCHS is currently linking various NCHS surveys with death certificate records from the the National Death Index (NDI), program participation and disability determination data from the Social Security Administration (SSA) and Medicare utilization and expenditure data from the Center for Medicare and Medicaid Services (CMS).
