Purpose of the NDI

• Identifies deceased study subjects
• Provides the following:
  • dates of death
  • states of death
  • death certificate numbers

Notes: NDI was implemented in 1982. It is a central computerized index to death record information on file in the state vital statistics offices.

Assists researchers who are conducting prospective or retrospective studies to determine which study subjects may have died.

  • Underlying cause of death codes

Notes: Before NDI Plus most users purchased death certificates from the states (1982-1997)

Then in 1997, after about 8 years of negotiations with the states, the NDI was permitted to release cause of death codes

Provides International Classification of Diseases codes – ICD codes
