Aims: Verbal autopsy (VA) is an attractive method for ascertaining causes of death in settings where the proportion of
people who die under medical care is low. VA has been widely used to determine causes of childhood and maternal deaths,
but has had limited use in assessing causes in adults and across all age groups. The objective was to test the feasibility of
using VA to determine causes of death for all ages in Bavi District, Vietnam, in 1999, leading to an initial analysis of the
mortality pattern in this area. Methods: Trained lay field workers interviewed a close caretaker of the deceased using a
combination closed/open-ended questionnaire. Results: A total of 189 deaths were studied. Diagnoses were made by two
physicians separately, with good agreement (k~0.84) and then combined to reach one single underlying cause of death for
each case. The leading causes of death were cardiovascular and infectious diseases (accounting for 20.6% and 17.9% of the
total respectively). Drowning was very prevalent in children under 15 (seven out of nine cases of drowning were in this age
group). Discussion: One month seemed an acceptable minimum recall period to ensure mourning procedures were over. A
combination VA questionnaire was an appropriate instrument provided it was supported by adequate training of
interviewers. Two physicians were appropriate for making the diagnoses but predefined diagnostic methods for common
causes should be developed to ensure more replicable results and comparisons, as well as to observe trends of mortality over
time. The causes of death in this study area reflect a typical pattern for developing countries that are in epidemiological
transition. No maternal deaths and a low infant mortality rate may be the result of improvements in maternal and child
health in this study area. Using the VA gave more precise causes of death than those reported at death registration.
Although the validity of the VA method used has not been fully assessed, it appeared to be an appropriate method for
ascertaining causes of death in the study area.
