Abstract:
|
The National Center for Health Statistics (NCHS) conducts mortality follow-up for its survey participants, creating an essential data resource for health research and policymaking. NCHS current mortality linkage employs a probabilistic matching process that uses Social Security Number (SSN) and other personal identifying information to select death records for survey participants. NCHS recently changed its collection of SSN information to include only the last four-digits, requiring an evaluation of linkage outcomes using partial SSN. Using the linkage of the National Health Interview Survey to death records, we compare linkage outcomes and mortality rates obtained using different SSN information. Findings will demonstrate the accuracy of partial SSN in record linkage and the utility of collecting such information for federal statistical agencies.
