Validation of Database Autopsy for Review of Pregnancy-Associated Deaths in Canada.

ABSTRACT

The database autopsy method was developed to determine probable causes of maternal deaths in the Canadian Institute for Health Information's hospital discharge abstract database; however, the method has yet to be validated. Using immediate cause of death information from Québec's hospitalization database as the gold standard, this study assessed the validity and reliability of the database autopsy method for pregnancy-associated deaths. The method had high sensitivity and specificity for identifying the most common causes of these deaths, as well as high interobserver agreement. We conclude that the database autopsy method is valid and reliable overall.
