Abstract:
|
The linked mortality file produced by the National Center for Health Statistics (NCHS) relies on a linkage algorithm for determining vital status based on whether a survey participant matched a death certificate record from the National Death Index. As part of a process to continually improve the linkage algorithm an evaluation was undertaken to determine if (1) the cutoffs for declaring match status should be changed and (2) the number of potential matches requiring manual review could be reduced. We merged the Household Component of the Medical Expenditure Panel Survey (MEPS) - a subsample of the National Health Interview Survey (NHIS) - to the linked mortality file. MEPS is a panel survey that follows participants for 2 years. At each round of data collection a participant is assigned a disposition code which was used in our analysis as a comparative measure of vital status to re-examine and re-estimate the sensitivity and specificity of our linkage algorithm. This analysis will help inform (1) potential improvements to the linkage algorithm used by NCHS to assess vital status of survey participants' and (2) the accuracy of mortality status data in a household panel survey.
