Verbal Autopsy

WHO Verbal autopsy standards:

In 2012, WHO published a revised shortened verbal autopsy (VA) questionnaire (called Release Candidate 1). The instrument has now been used in several field settings. In addition, other instruments have been developed based on validation studies. The Institute of Health Metrics and Evaluation at the University of Washington and its partners are also promoting a shortened VA questionnaire.
