Pretreatment stabilization increases completion of trauma-focused evidence-based psychotherapies

Abstract: Objective: Veterans with posttraumatic stress disorder (PTSD) initiate and complete cognitive processing therapy (CPT) and prolonged exposure (PE) at low rates within Veterans Health Administration (VHA) despite substantial dissemination and training. This study investigated how trauma-informed, skills-based treatment (“stabilization”) administered before CPT and PE was related to initiation and completion of trauma-focused evidence-based psychotherapies (TF-EBPs). Method: Data were extracted from the VHA electronic medical record to identify veterans who initiated outpatient treatment in the PTSD Clinical Team (PCT) at a Veterans Affairs Health Care System. Treatment initiation was defined as three or more PCT visits with no prior PCT care for at least 18 months (N = 341). Before initiation of TF-EBP, veterans received either no stabilization or received individual and/or group stabilization. Results: Twenty-eight percent of veterans without stabilization (n = 115) initiated TF-EBP, compared with 34% of veterans who completed individual-only stabilization (n = 82), and 10% of veterans who completed group-only stabilization (n = 29, p = .050). Compared with those with no stabilization, individual stabilization was associated with significantly higher TF-EBP completion (93% vs. 50%, p < .001). CPT completion was also significantly higher for veterans who received individual-only stabilization (90% vs. 43%, p = .001). Results for PE followed the same relationship, but did not reach significance (100% vs. 67%, p = .090). Conclusions: Findings suggest that individual stabilization may improve delivery of TF-EBPs in VHA settings by increasing TF-EBP completion without reducing initiation, while pretreatment with group-only stabilization may reduce initiation of TF-EBPs. Results inform how models of care can improve TF-EBP retention and completion among veterans with PTSD.

    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.
