Women veterans may experience a variety of traumatizing events and conditions before, during, and after their military service, such as intimate partner violence, military sexual trauma, moral injury, and posttraumatic stress disorder. These experiences put them at greater risk for significant behavioral and physical health sequelae, which can be associated with difficulty with civilian reintegration and complexities around homelessness. Homeless women military veterans are often uncounted, undergo different environmental situations than their male counterparts, and are vulnerable to sexual violence and unintended pregnancies. Identifying homeless women military veterans is an important first step; otherwise, they remain “invisible.” Comprehensive, collaborative, interdisciplinary health care in which trust is established and care is holistic and individualized will produce the most optimal outcomes.  相似文献

In cases of suspected violations of rules, regulations or the law by armed forces personnel, investigations are invariably mandatory. Military investigations differ from well-researched civilian criminal investigations. Differing from civilian police detectives, most military investigators – as disciplinary supervisors and military police personnel – have a number of tasks to accomplish, which include leading in combat and ensuring military readiness. Military investigations can lead to substantive negative or positive consequences for military readiness, including mental health, unit cohesion and subjective legal certainty. This impact on unit cohesion and mental health is influenced by any prior history of distress or trauma; military investigations are often preceded by contravention of internal disciplinary acts, complaints and traumatic events. This study explores factors in the differing military and legal systems of Germany and the United Kingdom (UK) that might help military personnel to successfully conduct investigations while ensuring deployment readiness and maintaining human rights.  相似文献

Suicide continues to be a significant public health problem in the United States and the Department of Defense (DoD). Timely and systematic postvention efforts can play an instrumental role in helping family members, peers, and military command to best manage the aftermath of a suicide. To date, several postvention efforts have been implemented in the military. However, there continues to be an overall lack of understanding of the specific short- and long-term effects of exposure to military suicide. In addition, more emphasis needs to be placed on empirically driven approaches to postvention and program evaluation. The purpose of this article is threefold: (1) to provide a summary of the postvention literature with special emphasis placed on the military organization; (2) to propose a conceptual model as a framework for understanding Military-Unit Suicide Survivorship; and (3) to briefly highlight postvention strategies within the DoD in the context of a number of research, clinical, and policy recommendations.  相似文献

Abstract

This paper reviews the military context of exposure to combat and deployment in Dutch soldiers. It does so by reviewing war victims and military psychiatry after WWII in the Netherlands, and describes Dutch deployments from the late 1970s to the present. ‘Who is the Dutch soldier’ is asked to articulate the mental load on the individual soldier before, during, and after deployment. The narrative review of this paper allows one to review how the armed forces personnel is challenged in relation to their specific assignment and in what respect the psychological dimensions are addressed and met in the face of risk and adversity. Finally, some critical considerations for future veterans care programmes are raised.  相似文献

Since September 11, 2001, the United States has engaged in an extended period of military conflict, resulting in 4.1 million men and women serving in support of Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn. Whereas not all servicemembers experience mental health issues, many have experienced difficulties with readjusting to the civilian world, often requiring mental health services both inside and outside of the Department of Veterans Affairs. Issues related to stigma and military culture contribute to barriers not only for veterans seeking treatment but for clinicians providing services who may lack experience with military culture. This article provides a framework to use military concepts in clinical sessions to further therapeutic engagement with the military/veteran client.  相似文献

Military personnel may encounter morally injurious events that lead to emotional, social, and spiritual suffering that transcend and/or overlap with mental health diagnoses (e.g., post‐traumatic stress disorder [PTSD]). Advancement of scientific research and potential clinical innovation for moral injury (MI) requires a diversity of measurement approaches. Drawing on results from the bifactor model in Currier et al.'s (2017) psychometric evaluation of the Expressions of Moral Injury Scale‐Military version (EMIS‐M), this study validated a four‐item short form of the instrument with two samples of veterans with a history of war‐zone service. Namely, despite the reduced number of items, the EMIS‐M‐Short Form (SF) yielded favourable internal consistency and comparable levels of convergent validity with theoretically related constructs (e.g., PTSD and struggles with morality and ultimate meaning) as the full‐length version. Notwithstanding the possible utility of distinguishing between self‐ and other‐directed forms of MI, factor analytic results further revealed that the EMIS‐M‐SF was best conceptualized with a unidimensional factorial model that might allow for a general assessment of MI‐related outcomes. Overall, these initial results suggest that the EMIS‐M‐SF may hold promise as a short, reliable, and valid assessment of overall outcomes related to a possible MI.  相似文献

PurposeAortic stenosis (AS) is the most common cause of adult valvular heart disease. In the past decade, minimally invasive surgery (MIS) to treat AS has gained popularity, especially if performed in combination with rapid deployment valves (RDVs), which shorten cross-clamp time (XCT). This study examines specific outcomes and related costs of aortic valve replacement (AVR) before and after the introduction of RDVs.MethodsWe used the AVR simulator, an economic model developed to correlate cost and resource utilization associated with the adoption of RDVs, to compare 2 scenarios: (1) a current scenario based on standard AVR practices and (2) a proposed scenario based on increasing use of RDVs and an MIS approach. Both scenarios involved 3 subgroups of patients treated with (1) conventional AVR, (2) MIS, and (3) AVR combined with a coronary artery bypass graft. The current scenario (status quo) involved patients treated with traditional biological valves, and the proposed scenario involved patients who underwent implantation with an RDV. The AVR simulator was fed with real-world input data to estimate complication rates and resource consumption in the proposed scenario. Real-world input data for this analysis were obtained from patients diagnosed with a symptomatic heart valve disease between 2015 and 2018, at Clinica-San-Gaudenzio, Novara, Italy. Lastly, the AVR simulator estimated hospital savings by comparing the 2 scenarios.FindingsA total of 132 patients underwent implantation with a traditional biological valve, and 107 were treated with a commercial valve system. The RDV was associated with an increase of 52% of patients undergoing MIS, which generated a 6.1-h reduction of XCT and a total savings of €6695. RDVs also reduced intensive care unit (ICU) and hospital ward length of stay (LOS), leading to savings of €677 and €595 per patient, respectively. Mortality and blood transfusions also improved. The savings for the hospital (related to shorter XCT, hospital ward LOS, and ICU LOS) amounted to €144.111. Our findings were consistent with data gathered from our real-word setting, and results of a sensitivity analysis indicate that our findings were robust across different possible situations.ImplicationsSwitching to RDVs and MIS procedures for AVRs was associated with a reduction of costs related to XCT, hospital ward LOS, and ICU LOS. Hospitals can upload literature- and experience-based clinical and cost values to the AVR simulator to estimate a hospital's performance with the introduction of RDVs compared with standard biological valves. This study was not randomized, so more extensive studies could confirm our results in the future.  相似文献
