This study analyzed the accuracy of the National Death Index when personal identifiers were used that included or excluded Social Security number. Computerized records of the Department of Veterans Affairs were used for comparison. Different combinations of identifiers other than Social Security number correctly identified from 83 to 92 percent of dead and 92 to 99 percent of living persons. These results should prove useful in ascertaining the mortality status of patient populations without information on Social Security numbers.
本研究分析了使用包含或排除社会安全号码的个人标识符时国家死亡指数的准确性。使用退伍军人事务部的计算机记录进行比较。除社会安全号码外的不同标识符组合能正确识别83%至92%的死亡人员和92%至99%的在世人员。这些结果在确定没有社会安全号码信息的患者群体的死亡状况方面应会很有用。
