本文报告了在美国癌症协会的前瞻性队列研究--癌症预防研究II中测试和使用国家死亡指数来确定生命状况的结果。这个由100多万名男性和女性组成的队列于1982年被志愿者招募，是有史以来与国家死亡指数联系在一起的最大队列之一。在通过人工跟踪追踪到1988年生命状况的15,000多人之间的联系中，93%的已知死亡得到了确定。敏感度因人口因素(种族、性别)和识别信息的可获得性(社会安全号码，中间字母)而异。当社会安全号码可用时，97%的已知死亡被准确识别。使用了计算机化的匹配算法，以最大限度地减少人工审查记录。通过这种方法，作者能够有效和准确地拒绝许多假阳性匹配，同时保持合理的人工记录审查和死亡证明获取水平，从而允许继续自动跟踪这一宝贵的队列。
This paper reports the results of testing and using the National Death Index to ascertain vital status in the American Cancer Society's prospective cohort study, Cancer Prevention Study II. This cohort of over one million men and women, enrolled by volunteers in 1982, is one of the largest ever to be linked with the National Death Index. In a linkage of over 15,000 persons whose vital status through 1988 had been traced through manual follow-up, 93% of all known deaths were ascertained. Sensitivity varied by demographic factors (race, sex) and availability of identifying information (Social Security number, middle initial). When the Social Security number was available, 97% of known deaths were accurately identified. A computerized matching algorithm was used to minimize manual review of records. With this method, the authors were able efficiently and accurately to reject the many false-positive matches while maintaining a reasonable level of manual record review and death certificate acquisition, thus allowing for continued automated follow-up of this valuable cohort.
