Introduction: Limited research has been conducted on the impact of deployment-related trauma exposure on post-traumatic stress symptoms in military medical personnel. This study evaluated the association between exposure to both combat experiences and medical duty stressors and post-traumatic stress symptoms in deployed military medical personnel.Materials and Methods: U.S. military medical personnel (N = 1,138; 51% male) deployed to Iraq between 2004 and 2011 were surveyed about their exposure to combat stressors, healthcare stressors, and symptoms of post-traumatic stress disorder (PTSD). All participants were volunteers, and the surveys were completed anonymously approximately halfway into their deployment. The Combat Experiences Scale was used as a measure of exposure to and impact of various combat-related stressors such as being attacked or ambushed, being shot at, and knowing someone seriously injured or killed. The Military Healthcare Stressor Scale (MHSS) was modeled after the Combat Experiences Scale and developed for this study to assess the impact of combat-related healthcare stressors such as exposure to patients with traumatic amputations, gaping wounds, and severe burns. The Post-traumatic Stress Disorder Checklist-Military Version (PCL-M) was used to measure the symptoms of PTSD.Results: Eighteen percent of the military medical personnel reported exposure to combat experiences that had a significant impact on them. In contrast, more than three times as many medical personnel (67%) reported exposure to medical-specific stressors that had a significant impact on them. Statistically significant differences were found in self-reported exposure to healthcare stressors based on military grade, education level, and gender. Approximately 10% of the deployed medical personnel screened positive for PTSD. Approximately 5% of the sample were positive for PTSD according to a stringent definition of caseness (at least moderate scores on requisite Diagnostic and Statistical Manual for Mental Disorders criteria and a total PCL-M score ≥ 50). Both the MHSS scores (r(1,127) = 0.49, p < 0.0001) and the Combat Experiences Scale scores (r(1,127) = 0.34, p < 0.0001) were significantly associated with PCL-M scores. However, the MHSS scores had statistically larger associations with PCL-M scores than the Combat Experiences Scale scores (z = 5.57, p < 0.0001). The same was true for both the minimum criteria for scoring positive for PTSD (z = 3.83, p < 0.0001) and the strict criteria PTSD (z = 1.95, p = 0.05).Conclusions: The U.S. military has provided significant investments for the funding of research on the prevention and treatment of combat-related PTSD, and military medical personnel may benefit from many of these treatment programs. Although exposure to combat stressors places all service members at risk of developing PTSD, military medical personnel are also exposed to many significant, high-magnitude medical stressors. The present study shows that medical stressors appear to be more impactful on military medical personnel than combat stressors, with approximately 5-10% of deployed medical personnel appearing to be at risk for clinically significant levels of PTSD.

Introduction: Traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD) are two of the signature injuries in military service members who have been exposed to explosive blasts during deployments to Iraq and Afghanistan. Acute stress disorder (ASD), which occurs within 2-30 d after trauma exposure, is a more immediate psychological reaction predictive of the later development of PTSD. Most previous studies have evaluated service members after their return from deployment, which is often months or years after the initial blast exposure. The current study is the first large study to collect psychological and neuropsychological data from active duty service members within a few days after blast exposure.Materials and Methods: Recruitment for blast-injured TBI patients occurred at the Air Force Theater Hospital, 332nd Air Expeditionary Wing, Joint Base Balad, Iraq. Patients were referred from across the combat theater and evaluated as part of routine clinical assessment of psychiatric and neuropsychological symptoms after exposure to an explosive blast. Four measures of neuropsychological functioning were used: the Military Acute Concussion Evaluation (MACE); the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS); the Headminder Cognitive Stability Index (CSI); and the Automated Neuropsychological Assessment Metrics, Version 4.0 (ANAM4). Three measures of combat exposure and psychological functioning were used: the Combat Experiences Scale (CES); the PTSD Checklist-Military Version (PCL-M); and the Acute Stress Disorder Scale (ASDS). Assessments were completed by a deployed clinical psychologist, clinical social worker, or mental health technician.Results: A total of 894 patients were evaluated. Data from 93 patients were removed from the data set for analysis because they experienced a head injury due to an event that was not an explosive blast (n = 84) or they were only assessed for psychiatric symptoms (n = 9). This resulted in a total of 801 blast-exposed patients for data analysis. Because data were collected in-theater for the initial purpose of clinical evaluation, sample size varied widely between measures, from 565 patients who completed the MACE to 154 who completed the CES. Bivariate correlations revealed that the majority of psychological measures were significantly correlated with each other (ps ≤ 0.01), neuropsychological measures were correlated with each other (ps ≤ 0.05), and psychological and neuropsychological measures were also correlated with each other (ps ≤ 0.05).Conclusions: This paper provides one of the first descriptions of psychological and neuropsychological functioning (and their inter-correlation) within days after blast exposure in a large sample of military personnel. Furthermore, this report describes the methodology used to gather data for the acute assessment of TBI, PTSD, and ASD after exposure to an explosive blast in the combat theater. Future analyses will examine the common and unique symptoms of TBI and PTSD, which will be instrumental in developing new assessment approaches and intervention strategies. [ABSTRACT FROM AUTHOR]

Introduction: Suicide is a significant problem in the U.S. military, with rates surpassing the U.S. general population as of 2008. Although there have been significant advances regarding suicide risk factors among U.S. military service members and veterans, there is little research about risk factors associated with suicide that could be potentially identified in theater. One salient study group consists of service members who receive a psychiatric aeromedical evacuation out of theater. The primary aims of this study were as follows: (1) determine the incidence of suicide-related aeromedical evacuation in deployed service members, (2) identify demographic and military characteristics associated with suicide-related aeromedical evacuation, and (3) evaluate the relationship between suicide-related aeromedical evacuation from a deployed setting and military separation.Materials and Methods: This was an archival analysis of U.S. Transportation Command Regulating and Command and Control Evacuation System and Defense Manpower Data Center electronic records of U.S. military service members (N = 7023) who were deployed to Iraq or Afghanistan and received a psychiatric aeromedical evacuation out of theater between 2001 and 2013. χ2 tests of independence and standardized residuals were used to identify cells with observed frequencies and proportions, respectively, that significantly differed from what would be expected by chance. In addition, odds ratios were calculated to provide context about the nature of any significant relationships.Results: For every 1000 psychiatric aeromedical evacuations that occurred between 2001 and 2013, 34.4 were suicide related. Gender, ethnicity, branch of service, occupation classification, and deployment theater were associated with suicide-related aeromedical evacuation (odds ratios ranged from 1.37 to 3.02). Overall, 53% of all service members who received an aeromedical evacuation for any psychiatric condition had been separated from the military for a variety of reasons (both voluntary and involuntary) upon record review in 2015. Suicide-related aeromedical evacuation was associated with a 37% increased risk of military separation compared to evacuation for another psychiatric condition (P < 0.02).Conclusions: Findings provide novel information on risk factors associated with suicide-related aeromedical evacuation as well as military separation following a suicide-related aeromedical evacuation. In many cases, the psychiatric aeromedical evacuation of a service member for suicidal ideations and their subsequent separation from active duty is in the best interest of the individual and the military. However, the evacuation and eventual military separation can be costly for the military and the service member. Consequently, the military should focus on indicated prevention interventions for individuals who show sufficient early signs of crisis and functional problems so that specialized interventions can be used in theater to prevent evacuation. Indicated prevention interventions should start with leaders' awareness and mitigation of risk and, when feasible, evidence-based interventions for suicide risk provided by behavioral health (eg, brief cognitive behavioral therapy for suicide). Future research should evaluate the feasibility, safety, and efficacy of delivering suicide-related interventions in theater. [ABSTRACT FROM AUTHOR]
