Linking the National Hospital Care Survey (NHCS) with the National Death Index (NDI) provides information on the outcomes of hospitalizations and allows for analysis of individual and provider characteristics associated with in-hospital and post-discharge mortality. We test the viability of confirming hospital mortality through the linkage of preliminary 2011 NHCS data for "known dead" inpatient discharges (i.e., patients that died during a hospitalization) with the NDI, assessing the true match rate and the quality of the match. We then expand the analysis to identify patients with a 30-, 60-, and 90-day post-discharge mortality. The true match rate for the "known dead" is 94 percent.
将国家医院护理调查（NHCS）与国家死亡指数（NDI）相链接，可提供有关住院治疗结果的信息，并能分析与住院期间及出院后死亡率相关的个体和医疗机构特征。我们通过将2011年NHCS关于“已知死亡”住院患者出院（即住院期间死亡的患者）的初步数据与NDI相链接，来测试确认医院死亡率的可行性，评估真正的匹配率和匹配质量。然后，我们扩大分析范围，以确定出院后30天、60天和90天内死亡的患者。“已知死亡”患者的真正匹配率为94%。
