Improving quality of mortality estimates among non-Hispanic American Indian and Alaska Native people, 2020

Résumé fourni par la source

Racial misclassification on death certificates leads to inaccurate mortality data for American Indian and Alaska Native (AI/AN) populations. We describe methods for correcting for racial misclassification among non-Hispanic AI/AN (NH-AI/AN) populations using data from the year 2020. We linked National Death Index records with the Indian Health Service (IHS) patient registration database to identify AI/AN decedents. Matches were then linked to the National Vital Statistics System mortality data to identify AI/AN individuals who had been misclassified as another race on their death certificates. Analyses were limited to NH-AI/AN and purchased/referred care delivery areas or urban areas. We compared death rates and counts pre- and postlinkage and calculated sensitivity and classification ratios by region, sex, age, cause of death, and urban area. Racial misclassification on death certificates among NH-AI/AN varied by geographic region. Some of the highest racial misclassification occurred in the Southern Plains and Pacific Coast. Death rates for NH-AI/AN people and differences between NH-AI/AN and non-Hispanic White people were larger using the linked data. Improving AI/AN mortality data using linkages between vital statistics data and IHS strengthens data quality and can help address health disparities through public health planning efforts.
