Self-reported hearing aid requirements among US military personnel and the association with probable posttraumatic stress disorder

Abstract: Background: Auditory problems are ubiquitous among U.S. military personnel. Hearing aids are an effective treatment for both hearing loss and tinnitus, two of the most common diagnoses among veterans awarded disability compensation, but the prevalence of hearing aid requirements in the U.S. military is unknown. Another military health problem is posttraumatic stress disorder (PTSD), an anxiety disorder characterized by exposure to a traumatic event. While some studies have found an association between auditory problems and PTSD, no research has examined the relationship between hearing aid requirements and PTSD. Purpose: To identify the prevalence of self-reported hearing aid requirements in U.S. military personnel and examine the association with PTSD. Research Design: Cross-sectional study. Study Sample: The study population included 104,728 U.S. Navy and Marine Corps service members who completed a Periodic Health Assessment between August and December 2021. Data Analysis: Prevalence of self-reported hearing aid requirements was calculated. A multivariable logistic regression model was used to determine the association between hearing aid requirements and PTSD, while adjusting for covariates. Results: Overall, 1.0% (1,088/104,728) of the study population self-reported requiring hearing aids. Hearing aid requirements were positively associated with age, and the highest prevalence was among those aged 40 years and older (3.8%). There was also a statistically higher prevalence among men compared with women (1.2 vs. 0.5%), Marines compared with Navy personnel (1.2 vs. 0.9%), and active duty compared with National Guard/Reserve components (1.1 vs. 0.6%). A significantly higher proportion of service members who required hearing aids screened positive for PTSD than those without hearing aids (30.4 vs. 7.5%). In multivariable regression, those who required a hearing aid, compared with those who did not, had more than three times higher odds of screening positive for PTSD (odds ratio: 3.45; 95% confidence interval: 3.00-3.96). Conclusion: To our knowledge, this is the first study to report the prevalence of self-reported hearing aid requirements in the U.S. military as well as an association between requiring hearing aids and screening positive for PTSD. Our findings reaffirm the need for interprofessional collaboration between audiologists and psychological health professionals when providing care for these patients.

    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.
