[Intentional search and reclassification of maternal deaths in Mexico: The effect on the distribution of causes]. / Búsqueda intencionada y reclasificación de muertes maternas en México: el efecto en la distribución de las causas.

OBJECTIVE: To correct the misclassification and improve the quality of information on maternal mortality in Mexico. MATERIALS AND 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.

Objetivo. Corregir la mala clasificación y mejorar la calidad de la información sobre la mortalidad materna en México. Material y métodos. A través de los registros clínicos y autopsias verbales, se estudiaron todas las defunciones certificadas como maternas y una selección de defunciones de mujeres en edad fértil, cuyas causas fueron consideradas como sospechosas de encubrir una muerte materna; todas ocurridas durante 2011 en México. Resultados. La búsqueda intencionada y reclasificación de muertes maternas permitió rescatar más de 100 muertes que no habían sido registradas ni codificadas inicialmente como maternas y se ratificaron o rectificaron las causas anotadas en los certificados de defunción. Este procedimiento también permitió reclasificar como muertes maternas 297 defunciones de la base preliminar del Instituto Nacional de Estadística y Geografía. Conclusiones. La Búsqueda Intencionada y Reclasificación de Muertes Maternas es un procedimiento muy útil para mejorar la calidad de la información sobre la mortalidad materna.
