The Idikan adult mortality study found verbal autopsies moderately useful for determining adult cause-specific mortality in developing countries. More hospital data are needed to confirm the technique's validity for adult death statistics.

Area of Science:

  • Public Health
  • Epidemiology
  • Demography

Background:

  • Cause-specific adult mortality data are scarce in developing nations.
  • Verbal autopsy (VA) is a potential method for collecting this data.

Purpose of the Study:

  • To assess the utility of the verbal autopsy methodology for determining cause-specific adult mortality.
  • To compare VA-assigned causes of death with hospital-recorded causes.

Main Methods:

  • A cohort of 4333 adults in an urban community was followed for 2 years.
  • Deaths were investigated using verbal autopsies administered by trained interviewers.
  • Two physicians independently assigned causes of death, with discrepancies resolved by a senior physician.

Main Results:

Related Experiment Videos

  • Verbal autopsy showed moderate agreement between independent coders (Kappa = 0.23) and with hospital-assigned causes (Kappa = 0.1).
  • Only 8 of 60 deaths occurred in hospitals during the study period.
  • The technique appears moderately useful for adult death statistics.

Conclusions:

  • Verbal autopsy is a moderately useful tool for adult mortality statistics in resource-limited settings.
  • Further research with a larger number of hospital deaths is required to definitively establish the validity of VA.
  • The study highlights the challenges and potential of VA in improving mortality data collection.
