项目摘要

Improving Suicide Prediction using NLP-Extracted Social Determinants of Health Suicide is among the leading causes of death worldwide and among United States Veterans in particular. Current methods of risk assessment are limited in their ability to accurately identify patients who are at the highest risk of suicide. The overarching goal of this proposal is to strengthen suicide prediction efforts by gaining a more granular understanding of the association between social determinants of health and suicide risk. Social determinants of health (SDH) refer to the conditions in which people are born, live, work, and age. A number of SDH are known risk factors for suicide. While SDH could be obtained from the structured EHR data, their scope is limited. A recent study has shown that EHR notes contain about 90 times more information about SDH than the structured data. To address this gap, we propose a stepwise approach that leverages the power of EHR and new computational methdologies to explore associations between natural language processing extracted SDH and suicide ideation, attempt and death. This approach is critical to the development of next- generation suicide prevention tools.

使用NLP提取的健康决定因素改善自杀预测自杀是全世界和美国退伍军人中死亡的主要原因之一特别的。当前的风险评估方法的准确识别能力有限自杀风险最高的患者。该提议的总体目标是通过获得对人的更加了解来加强自杀预测的努力健康决定因素与自杀风险之间的关联。卫生的社会决定因素（SDH）是指人们出生，生活，工作，和年龄。许多SDH是自杀的已知风险因素。虽然可以获得SDH 从结构化的EHR数据中，它们的范围有限。最近的一项研究表明EHR注意与结构化数据相比，有关SDH的信息包含的信息约为90倍。解决这个问题差距，我们提出了一种逐步的方法，该方法利用EHR和新计算的力量探索自然语言处理提取的SDH和自杀念头，企图和死亡。这种方法对于下一步的发展至关重要一代预防自杀工具。
