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 提取的健康社会决定因素改善自杀预测自杀是全球和美国退伍军人死亡的主要原因之一特别的。目前的风险评估方法在准确识别风险方面的能力有限。自杀风险最高的患者。该提案的总体目标是通过更细致地了解自杀事件来加强自杀预测工作健康的社会决定因素与自杀风险之间的关联。健康的社会决定因素（SDH）是指人们出生、生活、工作、和年龄。许多 SDH 是已知的自杀危险因素。虽然可以获得SDH 从结构化 EHR 数据来看，它们的范围是有限的。最近的一项研究表明 EHR 指出包含的有关 SDH 的信息比结构化数据多大约 90 倍。为了解决这个问题差距，我们提出了一种逐步的方法，利用 EHR 和新计算的力量探索自然语言处理提取的 SDH 和自杀意念、企图和死亡。这种方法对于下一代的发展至关重要一代自杀预防工具。
