Improved Casualty Depiction System for Simulated Mass Casualty Exercises.

INTRODUCTION: Assessing military medical teams' ability to respond to large-scale mass casualty (MASCAL) events has become a priority in preparing for future conflicts. MASCAL exercises rely on large numbers of simulated patients with limited medical training. Role-players must be appropriately prepared to ensure that medical exercises adequately assess the expected capabilities of military medical units. The Uniformed Services University of the Health Sciences (USUHS) has evaluated future military providers for decades using a large-scale, multiday, immersive simulation called Bushmaster. Despite a robust casualty training system, the fidelity of the portrayals remained limited. MATERIALS AND METHODS: Through collaboration with national military medical experts, a comprehensive casualty depiction system was developed. This system relied on structured casualty cards linked to time-based illness scripts. Structured casualty cards included an appropriate balance of disease non-battle injuries and trauma, included multipatient presentations based on shared events (i.e., multiple injured personnel due to an aircraft crash), normal and pathologic combat stress, population/unit considerations, requirements for different roles within the medical unit, and expected clinical outcomes. Illness scripts, supplemented by video guides, included time-based courses of illness/injury and prescribed responses to different typical treatments. This system was piloted during an annual MASCAL exercise (Operation Bushmaster) at USUHS. Clinical faculty were queried on the fidelity of this new system while role-players were evaluated on feasibility. RESULTS: Three hundred casualty cards linked to 49 illness scripts were created, peer-reviewed, and piloted at Bushmaster. A total of 170 military members with limited medical training portrayed simulated patients utilizing the new casualty depiction system. Clinical faculty members strongly agreed that the improved casualty depiction system improved the realism of individual patient presentations (96%). Eighty-three percent of role-players strongly agreed that the casualty depiction system was easy to understand. CONCLUSIONS: This improved casualty depiction system was a feasible approach to enhance the fidelity of a MASCAL exercise. It has since been shared with military medical units around the globe to assist with their MASCAL exercises, making future multisite evaluations of this casualty depiction system possible.

Development and Implementation of Web-Based Safety Planning Intervention Training for Firefighter Peer Support Specialists.

Background: Recent findings indicate that firefighters may be at increased risk for death by suicide; however, there has been only limited suicide prevention work in fire service to date. Aim: The objective of this program evaluation project was to develop and evaluate a web-based Safety Planning Intervention (SPI) training course for firefighter peer support specialists. Method: Peer support specialists who completed the web-based SPI training were administered evaluation questionnaires before the training and then again at a 3-month follow-up assessment. Results: A total of 213 peer support specialists completed the SPI training. Most participants took 2-3 h to complete the training. Participants generally reported high levels of satisfaction with the course, with the vast majority (94.4%) indicating they would recommend it to their peers. Course completers also demonstrated significant gains in SPI knowledge and self-efficacy from baseline to 3-month follow-up (all p's < .001). Moreover, the percentage of participants who reported completing a safety plan with someone they suspected at being of risk for suicide increased approximately 7-fold from baseline (3.5%) to 3-month follow-up (25.2%; p < .001). Participants further reported that 97.6% of the safety plans that they completed resulted in a positive outcome. Limitations: This was a program evaluation project that did not include a control group. Thus, causality cannot be inferred. Conclusions: The present findings suggest that web-based SPI training is a feasible and scalable approach for training peer support specialists to deliver the SPI to at-risk individuals.

Posttraumatic stress and delay discounting: a meta-analytic review.

Delay discounting-the extent to which individuals show a preference for smaller immediate rewards over larger delayed rewards-has been proposed as a transdiagnostic neurocognitive process across mental health conditions, but its examination in relation to posttraumatic stress disorder (PTSD) is comparatively recent. To assess the aggregated evidence for elevated delay discounting in relation to posttraumatic stress, we conducted a meta-analysis on existing empirical literature. Bibliographic searches identified 209 candidate articles, of which 13 articles with 14 independent effect sizes were eligible for meta-analysis, reflecting a combined sample size of N = 6897. Individual study designs included case-control (e.g. examination of differences in delay discounting between individuals with and without PTSD) and continuous association studies (e.g. relationship between posttraumatic stress symptom severity and delay discounting). In a combined analysis of all studies, the overall relationship was a small but statistically significant positive association between posttraumatic stress and delay discounting (r = .135, p < .0001). The same relationship was statistically significant for continuous association studies (r = .092, p = .027) and case-control designs (r = .179, p < .001). Evidence of publication bias was minimal. The included studies were limited in that many did not concurrently incorporate other psychiatric conditions in the analyses, leaving the specificity of the relationship to posttraumatic stress less clear. Nonetheless, these findings are broadly consistent with previous meta-analyses of delayed reward discounting in relation to other mental health conditions and provide further evidence for the transdiagnostic utility of this construct.

Incidence of Suicidal Ideation and Suicide Attempt Based on Time in a Deployed Environment.

INTRODUCTION: Knowing when suicidal ideation (SI) or suicide attempt (SA) is most likely to occur in a deployed environment would aid in focusing prevention efforts. This study aims to determine when evacuation for SA and SI is most likely to occur based on the absolute and relative number of months in a deployed setting. MATERIALS AND METHODS: This is a case-control study of active-duty military personnel evacuated from the U.S. Central Command area of responsibility for SI or an SA between April 1, 2020, and March 30, 2021. The arrival month and expected departure month were identified for all the included evacuees. The month of evacuation and proportion of completed deployment were compared. Secondary outcomes of mental health diagnosis or need for a waiver was also examined. RESULTS: A total of 138 personnel evacuated for SI or attempted suicide during the 12-month study period were included in the analysis. Evacuations occurring during month 3 of deployment were significantly higher (P < .0001) than those during other months. The 30% and 50% completion point of deployment had statistically higher frequencies of evacuations for SI/SA (<.0001). A secondary analysis revealed that 25.4% of the individuals had a documented preexisting behavioral health condition before deployment (P < .0001). CONCLUSION: Specific points along a deployment timeline were significant predictors for being evacuated for SI and SA.

Network analysis of posttraumatic stress disorder in a treatment-seeking sample of US firefighters and emergency medical technicians.

BACKGROUND: First responders, including firefighters and emergency medical technicians (EMTs), are under extreme stress from repeated exposure to potentially traumatic events. To optimize treatment for this population, it is critical to understand how the various posttraumatic stress disorder (PTSD) symptom factors are associated with one another so these relations may be targeted in treatment. METHOD: Using a sample of treatment-seeking firefighters/EMTs (N = 342), we conducted a partial correlation network analysis of the eight-factor model. A Bayesian directed acyclic graph (DAG) was used to estimate causal associations between clusters. RESULTS: Approximately 37 % of the sample screened positive for probable PTSD. Internal re-experiencing and external re-experiencing had the strongest edges. In the DAG, internal re-experiencing was the parent node and was potentially predictive of external re-experiencing, negative affect, dysphoric arousal, and avoidance. LIMITATIONS: Data were drawn from a treatment-seeking sample that may not generalize to all firefighters/EMTs. CONCLUSIONS: The current findings are consistent with prior research suggesting re-experiencing plays a critical role in developing and maintaining PTSD symptoms. Future research should investigate non-treatment-seeking first responders, as well as EMTs and firefighters as individual populations.

First Responder Attitudes Regarding Working Near a Supervised Injection Facility: Relationship to Burnout, Secondary Traumatic Stress, and Compassion Satisfaction.

BACKGROUND: Emergency responders are the most frequent overdose responders, however, little is known about the impact of supervised injection facility (SIF) location on first responders. The purpose of this study was to determine whether firefighter/paramedic attitudes about being stationed near an SIF were related to burnout, secondary traumatic stress, and compassion satisfaction. METHODS: Firefighter/paramedics from Vancouver Fire and Rescue Services (n = 54) completed an online survey. General linear models were used to assess differences in burnout, secondary traumatic stress, and compassion satisfaction based on attitudes regarding being stationed near an SIF while controlling for occupational stress. FINDINGS: Firefighters with negative attitudes regarding station placement near an SIF experienced more burnout compared with those with neutral/mixed attitudes and less compassion satisfaction compared with those with positive attitudes. There were no differences between those with positive and neutral/mixed attitudes. CONCLUSIONS: These findings have implications for education and training of emergency responders stationed near SIFs. They also highlight the need for more research into the effects of and possible clinical opportunities needed to support first responders' work near an SIF. APPLICATION TO PRACTICE: While these findings represent early exploratory evidence, increased burnout and reduced compassion satisfaction may be common reactions among first responders who experience negative attitudes toward SIFs. Prevention efforts could incorporate programs to enhance health and well-being of first responders and education regarding substance use and harm reduction, while workforce surveillance for signs of distress or burnout could be implemented to trigger additional mental health services and interventions. while policymakers should remain aware of SIF-related impacts on all stakeholders, including first responders.

Stamp Out Stigma: a national campaign to decrease stigma and increase behavioral health in fire service.

Firefighters are at risk for behavioral health problems; however, mental health stigma is a barrier to seeking treatment. Although effective treatments exist, many firefighters report that internal stigma prohibits presentation for effective care. This study aimed to decrease stigma about behavioral health in fire service through the development and delivery of a peer-led anti-stigma intervention campaign called Stamp Out Stigma (SOS). SOS consisted of three related phases. During Phase 1 (n = 12), we produced testimonials and piloted the videos with firefighters to determine which were most compelling. During Phase 2 (n = 23), we beta-tested our training curriculum with two departments, resulting in a significant decrease in internalized stigma but not in self-stigma. During Phase 3 (n = 73), we presented the curriculum to two cohorts of firefighters. Participation in the SOS workshop was associated with a significant decrease in firefighters' self-stigma from pre-, M = 22.7, SD = 6.3, to post-workshop, M = 20.8, SD = 5.5, t(66) = 3.2, p = 0.002. Participation in the SOS workshop was associated with a significant decrease in firefighters' internalized stigma, M = 2.0, SD = 0.5, to post-workshop, M = 1.8, SD = 0.4, t(66) = 2.8, p = 0.007. The SOS approach to stigma reduction is promising for modifying negative attitudes toward mental health and treatment seeking among professional firefighters.

MediLinker: a blockchain-based decentralized health information management platform for patient-centric healthcare.

Patients' control over how their health information is stored has been an ongoing issue in health informatics. Currently, most patients' health information is stored in centralized but siloed health information systems of healthcare institutions, rarely connected to or interoperable with other institutions outside of their specific health system. This centralized approach to the storage of health information is susceptible to breaches, though it can be mitigated using technology that allows for decentralized access. One promising technology that offers the possibility of decentralization, data protection, and interoperability is blockchain. In 2019, our interdisciplinary team from the University of Texas at Austin's Dell Medical School, School of Information, Department of Electrical and Computer Engineering, and Information Technology Services developed MediLinker-a blockchain-based decentralized health information management platform for patient-centric healthcare. This paper provides an overview of MediLinker and outlines its ongoing and future development and implementation. Overall, this paper contributes insights into the opportunities and challenges in developing and implementing blockchain-based technologies in healthcare.

A vocational rehabilitation partnership to provide transition services to young adults with neurodevelopmental disabilities: The cognitive skills enhancement program.

BACKGROUND: There is an urgent need for services that support a successful transition to postsecondary education and employment for young adults with neurodevelopmental and cognitive disabilities (e.g. autism spectrum disorder, attention-deficit/hyperactivity disorder, traumatic brain injury). OBJECTIVE: The purpose of this expository article is to describe the Cognitive Skills Enhancement Program (CSEP), a comprehensive clinical program designed for young adults with neurodevelopmental and cognitive disabilities transitioning to postsecondary education. METHODS: CSEP was developed through a community-academic partnership between a university and a state vocational rehabilitation program. Young adult participants complete programming that addresses four primary clinical targets: (1) emotion regulation, (2) social skills, (3) work readiness, and (4) community participation with the overall goal to increase awareness and promote successful employment outcomes while they transition to post-secondary education. RESULTS: To date, CSEP has supported 18 years of sustained programming and clinical services to 621 young adults with neurodevelopmental and cognitive disabilities. CONCLUSION: This partnership model allows for flexible responses to participant needs, implementation barriers, and advances in evidence-based practices. CSEP meets the needs of diverse stakeholders (e.g. state vocational rehabilitation, postsecondary training facilities, participants, universities) while providing high-quality and sustainable programming. Future directions include examining the clinical efficacy of current CSEP programming.

Dynamics of Gene Loss following Ancient Whole-Genome Duplication in the Cryptic Paramecium Complex.

Whole-genome duplications (WGDs) have shaped the gene repertoire of many eukaryotic lineages. The redundancy created by WGDs typically results in a phase of massive gene loss. However, some WGD-derived paralogs are maintained over long evolutionary periods, and the relative contributions of different selective pressures to their maintenance are still debated. Previous studies have revealed a history of three successive WGDs in the lineage of the ciliate Paramecium tetraurelia and two of its sister species from the Paramecium aurelia complex. Here, we report the genome sequence and analysis of 10 additional P. aurelia species and 1 additional out group, revealing aspects of post-WGD evolution in 13 species sharing a common ancestral WGD. Contrary to the morphological radiation of vertebrates that putatively followed two WGD events, members of the cryptic P. aurelia complex have remained morphologically indistinguishable after hundreds of millions of years. Biases in gene retention compatible with dosage constraints appear to play a major role opposing post-WGD gene loss across all 13 species. In addition, post-WGD gene loss has been slower in Paramecium than in other species having experienced genome duplication, suggesting that the selective pressures against post-WGD gene loss are especially strong in Paramecium. A near complete lack of recent single-gene duplications in Paramecium provides additional evidence for strong selective pressures against gene dosage changes. This exceptional data set of 13 species sharing an ancestral WGD and 2 closely related out group species will be a useful resource for future studies on Paramecium as a major model organism in the evolutionary cell biology.

The Effectiveness of Online Experiential Learning in a Psychiatry Clerkship.

OBJECTIVE: The Uniformed Services University of the Health Sciences 5-week psychiatry clerkship educates about 180 students a year at sites around the USA. In 2017, weekly in-person experiential learning sessions were implemented for local students and resulted in improved performance in several end-of-clerkship Objective Structured Clinical Examination (OSCE) skills as compared to distant learners who did not receive these sessions. The difference in performance (~ 10%) highlighted a need to provide comparable training for distant learners. Providing in-person, repeated simulated experiential training at multiple distant sites was not practical, requiring development of a novel online approach. METHODS: Students at all four distant sites over 2 years (n = 180) participated in five weekly synchronous online experiential learning sessions, while local students (n = 180) received five weekly in-person experiential learning sessions. Tele-simulation used the same curriculum, centralized faculty, and standardized patients as the in-person iterations. Overall end-of-clerkship OSCE performance was compared for learners receiving online versus in-person experiential learning for non-inferiority. Specific skills were compared to receiving no experiential learning. RESULTS: Overall OSCE performance was non-inferior for students who received synchronous online as compared to in-person experiential learning. Performance on each skill other than communication improved significantly when comparing students who received online versus no experiential learning (p < 0.05). CONCLUSIONS: The use of weekly online experiential learning to enhance clinical skills is comparable to in-person efforts. Virtual, simulated, synchronous experiential learning provides a feasible and scalable platform for training complex clinical skills to clerkship students, a critical capability given the impact the pandemic has had on clinical training.

Associations Among PTSD, Cognitive Functioning, and Health-Promoting Behavior in Post-9/11 Veterans.

INTRODUCTION: PTSD is associated with negative health behaviors that increase chronic disease risk, yet health behaviors and their determinants are not well investigated in this context. One understudied mechanism of health behaviors is cognitive functioning. Deficits in cognitive functioning may undermine engagement in health-promoting behavior, thereby increasing the negative impact of PTSD. We tested three hypotheses: (1) Greater PTSD symptom severity is associated with less health-promoting behavior; (2) greater PTSD symptom severity is associated with poorer cognitive functioning across verbal memory, processing speed, attention, and executive functioning domains; and (3) verbal memory and executive functioning exhibit indirect effects on the relationship between PTSD and health-promoting behavior. MATERIALS AND METHODS: We examined associations between PTSD symptom severity (Clinician-Administered PTSD Scale for DSM-IV), cognitive functioning, and health-promoting behavior (Health-Promoting Lifestyle Profile II) in 124 post-9/11 veterans (average age = 37.82; 85.5% male; 63.7% White; 18.5% Black; 26.6% Hispanic). Cognitive domains examined included verbal memory (California Verbal Learning Test), processing speed (Digit Symbol Coding), attention and working memory (Digit Span), and executive functions (Trail Making Test and Stroop Interference). RESULTS: Regression analyses indicated that greater PTSD symptom severity was associated with less health-promoting behavior (B = -.0101, SE = 0.0016, P < .0001; R2 = 0.3052). Path analyses revealed that verbal learning and memory partially accounted for this relationship (R2 = 0.037- 0.043; P < .05). CONCLUSIONS: Therapeutic targeting of these relationships may have implications for the prevention of long-term disease impact in veterans; longitudinal research is needed to elucidate the potential impact on chronic disease.

Massed vs Intensive Outpatient Prolonged Exposure for Combat-Related Posttraumatic Stress Disorder: A Randomized Clinical Trial.

Importance: Improved, efficient, and acceptable treatments are needed for combat-related posttraumatic stress disorder (PTSD). Objective: To determine the efficacy of 2 compressed prolonged exposure (PE) therapy outpatient treatments for combat-related PTSD. Design, Setting, and Participants: This randomized clinical trial was conducted among military personnel and veterans at 4 sites in Texas from 2017 to 2019. Assessors were blinded to conditions. Data were analyzed from November 2020 to October 2022. Interventions: The interventions were massed-PE, which included 15 therapy sessions of 90 minutes each over 3 weeks, vs intensive outpatient program PE (IOP-PE), which included 15 full-day therapy sessions over 3 weeks with 8 treatment augmentations. The IOP-PE intervention was hypothesized to be superior to massed-PE. Main Outcomes and Measures: Coprimary outcomes included the Clinician-Administered PTSD Scale for Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (DSM-5) (CAPS-5) and the PTSD Checklist for DSM-5 (PCL-5) administered at baseline and posttreatment follow-ups. Measures ranged from 0 to 80, with higher scores indicating greater severity. Diagnostic remission and reliable change were secondary outcomes. Results: Among 319 military personnel and veterans screened, 234 were randomized (mean [SD] age, 39.20 [7.72] years; 182 [78%] male participants), with 117 participants randomized to IOP-PE and 117 participants randomized to massed-PE. A total of 61 participants (26%) were African American, 58 participants (25%) were Hispanic, and 102 participants (44%) were White; 151 participants (65%) were married. Linear mixed-effects models found that CAPS-5 scores decreased in both treatment groups at the 1-month follow-up (IOP-PE: mean difference, -13.85 [95% CI, -16.47 to -11.23]; P < .001; massed-PE: mean difference, -14.13 [95% CI, -16.63 to -11.62]; P < .001). CAPS-5 change scores differed from 1- to 6-month follow-ups (mean difference, 4.44 [95% CI, 0.89 to 8.01]; P = .02). PTSD symptoms increased in massed-PE participants during follow-up (mean difference, 3.21 [95% CI, 0.65 to 5.77]; P = .01), whereas IOP-PE participants maintained treatment gains (mean difference, 1.23 [95% CI, -3.72 to 1.27]; P = .33). PCL-5 scores decreased in both groups from baseline to 1-month follow-up (IOP-PE: mean difference, -21.81 [95% CI, -25.57 to -18.04]; P < .001; massed-PE: mean difference, -19.96 [95% CI, -23.56 to -16.35]; P < .001) and were maintained at 6 months (IOP-PE: mean change, -0.21 [95% CI, -3.47 to 3.06]; P = .90; massed-PE: mean change, 3.02 [95% CI, -0.36 to 6.40]; P = .08). Both groups had notable PTSD diagnostic remission at posttreatment (IOP-PE: 48% [95% CI, 36% to 61%] of participants; massed-PE: 62% [95% CI, 51% to 73%] of participants), which was maintained at 6 months (IOP-PE: 53% [95% CI, 40% to 66%] of participants; massed-PE: 52% [95% CI, 38% to 66%] of participants). Most participants demonstrated reliable change on the CAPS-5 (61% [95% CI, 52% to 69%] of participants) and the PCL-5 (74% [95% CI, 66% to 81%] of participants) at the 1-month follow-up. Conclusions and Relevance: These findings suggest that PE can be adapted into compressed treatment formats that effectively reduce PTSD symptoms.

The influence of cannabis use disorder on post-traumatic stress disorder symptoms, depression symptoms, and non-suicidal self-injury among college students.

Objective: The interrelationships between cannabis use disorder (CUD), post-traumatic stress disorder (PTSD) and depressive symptoms, and non-suicidal self-injury (NSSI) were examined. Participants: Undergraduates (N = 363) who reported using cannabis within the past six months were recruited. Method: Mediation analyses was conducted to examine if CUD symptoms were indirectly associated with greater risk for engagement in current NSSI through more severe PTSD and depression symptoms. A factor comprised of PTSD-depression symptoms was created given PTSD and depression symptoms were highly correlated. Results: Greater CUD symptom severity indirectly increased risk for current NSSI via more severe PTSD-depression symptoms, after accounting for gender and alcohol use disorder symptoms. Conclusion: The current study provides preliminary evidence for the negative consequences of CUD on college students' mental health symptoms and engagement in NSSI, and future longitudinal research is needed to examine the dynamic relationships between CUD, PTSD-depression symptoms, and NSSI over time.

A brief report on the temporal relations between social functioning and behavioral health among veterans.

Using a four-wave longitudinal design, three competing hypotheses (i.e., social selection, social causation, and reciprocal causation) were tested pertaining to the relation between social functioning and several indices of behavioral health [i.e., post-traumatic stress symptoms (PTSS), distress, and alcohol-related problems] among military veterans exposed to trauma. Across two latent growth curve analyses, data largely supported longitudinal links between improved social functioning and positive behavioral health, often indicating that the improvements in social functioning frequently precede improvements in behavioral health. Overall, findings underscore the merit of directly targeting social functioning as part of mental health treatment among trauma-exposed individuals.

Satisfaction and feasibility of videoconsultation (VC) in orthopaedic and trauma surgery in the context of the COVID-19 pandemic: Prospective study of 783 patients.

BACKGROUND: The COVID-19 pandemic has required that specialists use videoconsultation (VC) to maintain continuity of care. As in-person consultations (IPCs) and surgical procedures were cancelled, VC became the tool of choice. No recent French study has assessed VC as the main consultation modality. The objective of this prospective study was to evaluate: 1) patient satisfaction, 2) access to and the future of VC, 3) and the reasons for VC refusal in the setting of the pandemic. HYPOTHESIS: Patients responded favourably to VC. PATIENTS AND METHOD: We conducted a prospective, single-centre, observational study of consecutive patients who were invited to switch from IPC to VC during the lockdown of March 16 to May 11, 2020, when IPCs were not available. All patients were included in the study, regardless of whether they accepted the VC. The reasons for refusal were recorded at the time of the invitation. The surgeons sent the patients who accepted an emailed satisfaction questionnaire after the VC. RESULTS: Of the 783 patients with scheduled IPCs, 291 (37.2%) accepted a VC instead, 408 (52.1%) refused the VC, and 84 (10.7%) could not be contacted by telephone and were therefore excluded. The VC acceptance rate was 37% (291/783). Of the 291 VC patients, 233 (80.1%) returned the satisfaction questionnaire, although 2 questionnaires had too many missing data to be included, leaving 231 patients for the analysis. The VC was the first consultation with the surgeon for 66 (28.6%) patients. Of the 165 (71.4%) other patients, 51.6% (85/165) were receiving post-operative follow-up. On a 0-5 scale, the global VC experience was scored 4.3±0.8. Of the 231 VC patients, 161 (69.7%) felt that the VC was equivalent to an IPC, 18 (7.8%) that it was poorer, and 7 (3%) that it was better than an IPC; 45 (19.5%) had no opinion on this point. If choosing between a VC or an IPC had been possible during this first lockdown, 168/231 (72.7%) patients would have chosen an IPC. In contrast, 198/231 (85.7%) patients said they would choose an IPC after the lockdown. The group that refused the VC had a significantly older mean age (57.8±16.4 years vs. 48.0±14.4 years, p<0.0001) and lived closer to the institution (p<0.0001), whereas the sex distribution was comparable, with 42.9% of males (175/408) refusing and 46.8% (108/231) accepting the VC (p=0.39). The main reason for refusal was a wish for an in-person encounter with the surgeon (268/408, 65.7%). Patients aged ≥65 years were more likely to refuse due to technical considerations (access to electronic equipment and to the Internet), whereas patients ≤35 years were more likely to wait for an IPC. CONCLUSION: The rate of satisfaction with the VC was high. Satisfaction was not significantly associated with the reason for the consultation (joint involved, degenerative or post-traumatic condition, first VC, first consultation, or follow-up before or after surgery). Although most patients who accepted the VC felt that this modality was equivalent to an IPC, many remained desirous of an in-person encounter with the surgeon, notably among the youngest individuals. Outside the setting of a pandemic, the IPC remains the consultation modality of choice for most of our patients. LEVEL OF EVIDENCE: V, prospective study without a control group.

Suicide attempts and mental health diagnoses in combat-injured service members: A retrospective cohort study.

INTRODUCTION: Examinations of risk factors for suicide attempt in United States service members at high risk of mental health diagnoses, such as those with combat injuries, are essential to guiding prevention and intervention efforts. METHODS: Retrospective cohort study of 8727 combat-injured patients matched to deployed, non-injured patients utilizing Department of Defense and Veterans Affairs administrative records. RESULTS: Combat injury was positively associated with suicide attempt in the univariate model (HR = 1.75, 95% CI 1.5-2.1), but lost significance after adjustment for mental health diagnoses. Utilizing Latent Transition Analysis in the combat-injured group, we identified five mental/behavioral health profiles: (1) Few mental health diagnoses, (2) PTSD and depressive disorders, (3) Adjustment disorder, (4) Multiple mental health comorbidities, and (5) Multiple mental health comorbidities with alcohol use disorder (AUD). Multiple mental health comorbidities with AUD had the highest suicide attempt rate throughout the study and more than four times that of Multiple mental health comorbidities in the first study year (23.4 vs. 5.1 per 1000 person years, respectively). CONCLUSION: Findings indicate that (1) combat injury's impact on suicide attempt is attenuated by mental health and (2) AUD with multiple mental health comorbidities confers heightened suicide attempt risk in combat-injured service members.

Enhancing resiliency and optimizing readiness in military personnel through psychological flexibility training: design and methodology of a randomized controlled trial.

Background: Enhancing resiliency and optimizing readiness in military personnel is a high priority for the U.S. Department of Defense. Most military resiliency-enhancement programs are evidence-informed interventions. However, few randomized studies have demonstrated efficacy of any intervention or training program to enhance resiliency and prevent the development of psychological health symptoms in military personnel when exposed to operational stressors. This manuscript provides an overview of the theoretical foundation, research design, and research methods of a preventive intervention trial designed to evaluate the efficacy of a training program to enhance resiliency and prevent psychological health symptoms in military personnel. The resiliency training intervention is based on Acceptance and Commitment Therapy (ACT), an evidence-based intervention with broad empirical support for improving functioning in those living with psychological and medical conditions. Method/design: This study will evaluate the efficacy of a two-day training program based on ACT for fostering psychological flexibility, the central target in ACT, for enhancing resiliency, and for preventing the development of psychological health symptoms. The research participants will be a non-clinical population of active duty military personnel (N = 600). The ACT-based training program (n = 300) will be compared to a military resiliency training as usual, known as Master Resilience Training (n = 300). Assessment measures will be administered at the baseline assessment, after training, prior to a military deployment, and after returning from a deployment. Qualitative interviews will be conducted to provide feedback on the training program.Clinical Trial Registration: NCT05094115.
