The five-year NIMH grant is intended to predict suicidal ideation and suicide attempt by tapping into routine EHRs\u2014including clinician notes\u2014as well as data from a Vanderbilt and UK biobank.Researchers will leverage Vanderbilt\u2019s BioVU, the world\u2019s largest repository of human DNA stored at a single site, which is linked to de-identified health records. In addition, colleagues from Stanford University will use data from the UK Biobank to conduct genetic analyses of suicidal ideation risk in a second population.\u201cExpanding our capture of suicidal phenotypes will enable improved understanding of the genetic architecture of suicidal thoughts and behaviors and the contributing genetic and clinical risk factors,\u201d said principal investigator Douglas Ruderfer, VUMC assistant professor of medicine, psychiatry and behavioral sciences and biomedical informatics.\u201cWhile most individuals who consider suicide do not attempt it, we know ideation is an important risk factor and, if identified, could provide a flag for patients whom we might be able to help,\u201d adds Ruderfer.","saveContent":"The National Institute of Mental Health has awarded researchers at Vanderbilt University Medical Center a $2.7 million grant to study the use of artificial intelligence for the prediction of suicide risk.VUMC investigators will leverage predictive algorithms previously developed using machine learning and electronic health record data to assign suicide risk scores to thousands of genotyped patients.\u201cIn this study, we tackle two key challenges,\u201d says principal investigator Colin Walsh, MD, VUMC assistant professor of biomedical informatics, medicine and psychiatry and behavioral sciences. \u201cFirst, we know that many cases of suicidal thoughts and behaviors are missed if we rely on structured data alone.
