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.
