National Hospital Care Survey [NHCS] Linked to National Death Index [NDI] Data
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.
