Association between use of services to address adverse social determinants of health and documented suicide attempt among patients in the Veterans Health Administration

Abstract: Suicide prevention is a top priority for the US Department of Veterans Affairs (VA), and suicide is often associated with adverse social factors (e.g., financial, legal, and housing problems). The VA provides social services integrated with healthcare services, which may increase the opportunities to detect and document suicide attempt in EHR records. Using VA administrative data, we examined three cohorts of all patients from 2014 to 2018 who had housing instability (n = 659,987), justice involvement (n = 200,487), and unemployment (n = 346,556). Administrative records were used to determine ordinal indicators of receipt of VA social services (no services, low, or high). The outcome was suicide attempt noted in the healthcare record (i.e., documented suicide attempt) in the 1-6 months following the incident adverse social factor. We conducted logistic regressions utilizing a discrete-time survival framework with person-month as the unit of analysis, which facilitated accounting for covariates while isolating the independent association of social service utilization. After adjusting for covariates, high receipt of housing services (vs. no services) was significantly associated with documented suicide attempt during the 6-month observation period (aOR = 1.14, 95%CI = 1.06-1.22). A similar association was observed for high vs. no use of justice programs (aOR 1.24; 95% CI:1.12-1.37). There was no significant association between employment services utilization and documented suicide attempt during the 6-month observation period. Our finding that utilization of social services as positively associated with documented suicide attempt likely reflects increased suicide attempt surveillance and documentation with social service involvement. Future research should explore operationalizing patient-level distress in administrative data.

    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.
