We evaluate the ability of a microcomputer program (Automatch) to link patient records in our hospital's database (N = 253,836) with mortality files from California (N = 1,312,779) and the U.S. Social Security Administration (N = 13,341,581). We linked 96.5% of 3,448 in-hospital deaths, 99.3% for patients with social security numbers. None of 14,073 patients known to be alive (because they were subsequently admitted) was linked with California deaths, and only 6 (0.1%) of 6,444 were falsely identified as dead in the United States file. For patients with unknown vital status but items in the database likely to be associated with high 3-year mortality rates, we identified death records of 88% of 494 patients with cancer metastatic to the liver, 84% of 164 patients with pancreatic cancer, and 91% of 126 patients with CD4 counts of less than 50. Hospital data can be accurately linked with state and national vital statistics using commercial record linkage software.
我们评估了一个微型计算机程序（Automatch）将我们医院数据库中的患者记录（N = 253,836）与加利福尼亚州的死亡档案（N = 1,312,779）以及美国社会保障管理局的档案（N = 13,341,581）相链接的能力。我们成功链接了3448例住院死亡病例中的96.5%，对于有社会保障号码的患者，链接成功率为99.3%。已知存活的14073例患者（因为他们随后又入院了）中，没有一例与加利福尼亚州的死亡记录相链接，在美国档案中，6444例患者中只有6例（0.1%）被错误地认定为死亡。对于生命状态未知但数据库中有可能与3年高死亡率相关项目的患者，我们找到了494例肝转移癌患者中88%的死亡记录、164例胰腺癌患者中84%的死亡记录以及126例CD4细胞计数低于50的患者中91%的死亡记录。使用商业记录链接软件，医院数据可以与州和国家的人口动态统计数据准确链接。
