Associations Between Natural Language Processing-Enriched Social Determinants of Health and Suicide Death Among US Veterans.

ABSTRACT:

Importance

Social determinants of health (SDOHs) are known to be associated with increased risk of suicidal behaviors, but few studies use SDOHs from unstructured electronic health record notes.

Objective

To investigate associations between veterans' death by suicide and recent SDOHs, identified using structured and unstructured data.

Design, setting, and participants

This nested case-control study included veterans who received care under the US Veterans Health Administration from October 1, 2010, to September 30, 2015.
