Pain and Post-traumatic Stress Disorder Symptoms: Dyadic Relationships Between Canadian Armed Forces Members/Veterans With Chronic Pain and Their Offspring

Abstract: Chronic pain and mental health issues occur at higher rates in Veterans than the general population. One widely recognized mental health issue faced by Veterans is post-traumatic stress disorder (PTSD). Trauma symptoms and pain frequently co-occur and are mutually maintained due to shared mechanisms. Many Veterans are also parents. Parental physical and mental health issues significantly predict children's chronic pain and related functioning, which can continue into adulthood. Only one US-based study has examined pain in the offspring of Veterans, suggesting heightened risk for pain. Research to date has not examined the associations between trauma and pain, and the dyadic influences of these symptoms, among Veterans and their children. The current study aimed to describe pain characteristics in Canadian Armed Forces (CAF) Members/Veterans with chronic pain and their offspring (youth and adult children aged 9-38). Cross-lagged Panel Models (CLPM) were conducted to examine dyadic relationships between pain interference and trauma symptoms of CAF Members/Veterans and their offspring. Over half of adult offspring and over one quarter of youth offspring reported chronic pain. Results revealed effects between one's own symptoms of PTSD and pain interference. No significant effects of parents on offspring or offspring on parents were found. The findings highlight the interconnection between pain and PTSD consistent with mutual maintenance models, and a lack of significant interpersonal findings suggestive of resiliency in this unique population. PERSPECTIVE: We characterized chronic pain in offspring of Canadian Armed Forces Members/Veterans with chronic pain and examined dyadic relationships between PTSD symptoms and chronic pain interference. Findings revealed that PTSD symptoms and pain interference were related within Veterans and offspring, but no dyadic relationships were found, which could reflect resiliency.

    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.
