Improving ascertainment of suicidal ideation and suicide attempt with natural language processing

2022-02-27

Abstract excerpt

<h4>Methods: </h4> relying on diagnostic codes to identify suicidal ideation and suicide attempt in Electronic Health Records (EHRs) at scale are suboptimal because these phenotypes are heavily under-coded. We propose to improve the ascertainment of suicide phenotypes using natural language processing (NLP). We developed information retrieval methodologies to search over 200 million notes from the Vanderbilt EHR....
