Abstract
LOZANO-ESPARZA, Susana; ZAZUETA, Oscar E; HERNANDEZ-AVILA, Juan Eugenio and LAJOUS, Martín. Comparing the usefulness of two mortality registries for data-linkage for prospective cohorts in Mexico. Salud pública Méx [online]. 2022, vol.64, n.1, pp.96-99. Epub Mar 06, 2023. ISSN 0036-3634. https://doi.org/10.21149/13384.
Objective:
To estimate the sensitivity and specificity of two Mexican death registries for the identification of vital status using a publicly available record-linkage tool.
Materials and methods:
We selected all reported deaths (n=581) and 575 alive participants in an epidemiologic cohort with active follow-up. Individual records were cross-linked to two mortality registries.
Results:
A sensitivity of 87.2% (95%CI: 84.7, 90.2) and specificity of 99.3% (95%CI: 98.2, 99.8) were jointly achieved with both registries. Major discrepancies in cause of death were observed in 10.8% of deaths.
Conclusion:
There is initial evidence that Mexican death registries are a valuable resource for mortality follow-up in epidemiologic studies.
