The interaction between alcohol misuse and belongingness on suicidal ideation among military personnel

Abstract: Previous research suggests a high prevalence of suicidal ideation among military personnel. Suicidal ideation is associated with suicide attempts and death. This study focused on the association between belongingness-a component of the Interpersonal Psychological Theory of Suicide-and alcohol misuse on suicidal ideation among the different categories of military branch and military service status. Using the Military Suicide Research Consortium Common Data Elements database (N = 2516), we conducted linear regression analyses to examine the moderating effect of belongingness and alcohol misuse on the association between military branch and military service status (i.e., Active Duty) on suicidal ideation. Results showed a negative significant association between belongingness and suicidal ideation, and a positive significant association between alcohol and suicidal ideation. The results indicated that alcohol misuse moderated the association between military branch and suicidal ideation, but did not moderate the association between military service status and suicidal ideation. Additionally, the results indicated that belongingness moderated the association between military branch and suicidal ideation and the association between military service status and suicidal ideation. The results highlight the differences across military branches and military service statuses and suggest the importance of developing tailored suicide prevention programs to address the specific needs of each military subpopulation.

    Identifying opioid relapse during COVID-19 using natural language processing of nationwide Veterans Health Administration electronic medical record data

    Abstract: Novel and automated means of opioid use and relapse risk detection are needed. Unstructured electronic medical record data, including written progress notes, can be mined for clinically relevant information, including the presence of substance use and relapse-critical markers of risk and recovery from opioid use disorder (OUD). In this study, we used natural language processing (NLP) to automate the extraction of opioid relapses, and the timing of these occurrences, from veteran patients' electronic medical record. We then demonstrated the utility of our NLP tool via analysis of pre-/post-COVID-19 opioid relapse trends among veterans with OUD. For this demonstration, we analyzed data from 107,606 veterans OUD enrolled in Veterans Health Administration, comparing a pandemic-exposed cohort (n = 53,803; January 2019-March 2021) to a matched prepandemic cohort (n = 53,803; October 2017-December 2019). The recall of our NLP tool was 75% and our precision was 94%, demonstrating moderate sensitivity and excellent specificity. Using the NLP tool, we found that the odds of opioid relapse postpandemic onset were proportionally higher compared to prepandemic trends, despite patients having fewer mental health encounters from which to derive instances of relapse postpandemic onset. In this research application of the tool, and as hypothesized, we found that opioid relapse risk was elevated postpandemic. The application of NLP Methods: to identify and monitor relapse risk holds promise for future surveillance, risk prevention, and clinical outcome research.
