Mortality Matters: Linking EHR with Multiple Death Data Sources for Accurate Outcome Analyses

Survival analysis is fundamental to countless areas of health research and treatment effectiveness studies. Analyses that consider only deaths recorded in the EHR under-represents true mortality. By linking EHR and third-party death data through the use of de-identified tokens, researchers can conduct survival analysis with greater confidence all while protecting PHI.

In this discussion, speakers from Datavant and TriNetX will share:

• The impact of more complete mortality data on survival risk analysis
• The strengths and limitations of common sources of death data
• Gain best practices in the linking of mortality data from various sources
