Strategies for using the National Death Index and the Social Security Administration for death ascertainment in large occupational cohort mortality studies.

This paper describes a multistage process to improve the completeness and time-/cost-effectiveness of ascertaining deaths in large employee cohorts. The process uses the vital status data service of the Social Security Administration (SSA) to identify people who can be confirmed as living, in order to reduce the number of records submitted for a National Death Index (NDI) search. The accuracy of SSA results is verified by submitting a sample of known-living and known-deceased people.

Mortality updates (1970-1997) of two refinery/petrochemical plant cohorts at Baton Rouge, Louisiana, and Baytown, Texas.

Objective: The purpose of this retrospective cohort study is to update mortality experience at refinery/petrochemical plant facilities in Baton Rouge, Louisiana, and Baytown, Texas.

Methods: Standardized mortality ratios (SMRs) were calculated for 1970-1997 based on death rates in the respective states.

Results: SMRs are near or below unity for most causes of death.
