Validating the verbal autopsy questionnaire for maternal mortality in pakistan

Area of Science:

• Public Health
• Demography
• Epidemiology

Background:

• Maternal mortality presents a significant global health disparity, with ratios up to 40 times higher in some African countries than in Northern Europe.
• The maternal mortality ratio (MMR) serves as a key indicator of women's societal status and the accessibility of maternal healthcare.
• Existing data collection methods require validation to accurately capture maternal mortality causes.

Purpose of the Study:

• To assess the agreement between hospital-assigned causes of death and obstetrician reviews using a verbal autopsy (VA) questionnaire.
• To validate the sensitivity and specificity of the VA questionnaire for the Pakistan Demographic and Health Survey (PDHS) 2007.
• To identify methods for enhancing the accuracy of verbal autopsy data collection.

Main Methods:

• A validation study was conducted by the National Institute of Population Studies (NIPS) from July to September 2006.
• The study involved reviewing completed VA questionnaires to compare assigned causes and categories of death.
• The sensitivity and specificity of the VA questionnaire were tested.

Main Results:

• The study aimed to determine the level of agreement between different methods of assigning causes of death.
• Validation of the VA questionnaire's sensitivity and specificity was a primary objective.
• The study highlighted the importance of rigorous training for review panelists.

Conclusions:

• Rigorous training of review panelists in utilizing coded questionnaire information can enhance the sensitivity of the VA technique.
• Accurate data collection is essential for understanding and addressing maternal mortality.
• Improving verbal autopsy methods is key to reducing the gap in maternal mortality rates.
