In 2002 the Mexican MoH started a passive identification of maternal deaths in women of reproductive age using death certificates recorded and a special list of potential causes of maternal or pregnancy related deaths
Collecting all information available of each “potential maternal death”: Medical records, Verbal Autopsy, Death Certificate, Maternal Mortality Committee Report, Critical Links of maternal deaths, etc.
Corroborate one by one with INEGI database and Incorporating those which qualify as new registries into the “official” mortality database (INEGI)
1,320 Mat. deaths added = 13.2% in 8 years % Deaths

Studies such as undertaken in Mexico can then lead both to improved ascertainment through training of those involved in certification and provide a basis for improved garbage code reassignment algorithms.
Verbal autopsy for a representative sample of deaths can be obtained through three strategies:
Using verbal autopsy in a sample of communities where there is active surveillance of deaths e.g. SRS in India
Using verbal autopsy as a follow-up to a national census that included questions on deaths in the recent time period. Deaths in the recent time period will be an undercount but the cause-specific mortality fractions should be useful if the recall of death is not related to the cause of death
Using verbal autopsy in household surveys. Verbal autopsy can be included for sibling deaths and deaths in the household
