title: [Intentional search and reclassification of maternal deaths in Mexico: The effect on the distribution of causes].
abstract: OBJECTIVE
  To correct the misclassification and improve the quality of information on maternal mortality in Mexico.
  
  
  METHODS
  Using clinical records and verbal autopsies, we studied all deaths certified as maternal deaths as well as a selection of deaths of women of childbearing age whose causes were considered as suspected of hiding a maternal death, all of which occurred during 2011 within Mexico.
  
  
  RESULTS
  The deliberate search of maternal deaths and reclassification allowed the rescue of just over 100 deaths that were not originally registered or coded as maternal and confirmed or corrected the causes of death recorded on death certificates as confirmed maternal deaths. This procedure also allowed the reclassification of 297 maternal deaths of women in the groundwork of the National Institute of Statistics and Geography.
  
  
  CONCLUSIONS
  International Search and Reclassification of Maternal Deaths is a very useful procedure for improving the classification of cases that were not classified as maternal deaths and the effect was greater with the coding of indirect obstetric deaths.
