Abstract

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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
