Application review process

Researchers who want to use the National Death Index (NDI) must go through the rigorous application process and sign confidentiality documents. The independent NDI review board reviews every application. The board then approves or disapproves each project.

NDI advisors review each application to ensure that state data, including Personally Identifiable Information (PII), are protected against misuse.

The NDI application review process takes approximately 2–3 months.

Application review criteria

When reviewing NDI applications, several criteria are considered—

  1. Project's statistical purpose
  2. Whether, how, and why the project proposes to provide third parties with access to identifiable data
  3. Project's approval by an Institutional Review Board for the protection of human subjects
  4. Whether the project will be doing a follow-up with next-of-kin or health care providers
  5. Whether the project will keep NDI data in a data registry, long-term study, or surveillance
  6. Whether, how, and why the project proposes to provide third parties with access to identifiable data
  7. Project's plan for final disposition or retention of identifiable data

NDI advisors have contributed to the evolution of these criteria. NDI advisers will continue revising these criteria, as needed, to address new issues or accommodate unique situations identified in future NDI applications.

NDI advisors

NDI advisors are a mix of state vital records and health statistics staff, as well as outside researchers and health scientists.
