Characteristics of traumatic brain injury during Operation Enduring Freedom-Afghanistan: a retrospective case series.

Traumatic brain injury (TBI) is a significant cause of morbidity and mortality, especially among members of the armed services. Injuries sustained in the battlefield are subject to different mechanisms than those sustained in civilian life, particularly blast and high-velocity injury. Due to the unique nature of these injuries and the challenges associated with battlefield medicine, surgical interventions play a key role in acute management of TBI. However, the burden of chronic disease posed by TBI is poorly understood and difficult to investigate, especially in the military setting. The authors report the case logs of a United States Navy neurosurgeon, detailing the acute management and outcomes of 156 patients sustaining TBI between November 2010 and May 2011 during the war in Afghanistan. By demographics, more than half of the patients treated were local nationals. By mechanism of injury, blunt trauma (40.4%) and explosive injury (37.2%) were the most common contributors to TBI. Decompressive craniectomies (24.0%) and clot evacuations (14.7%) were the procedures most commonly performed. Nearly one-quarter of patients were transferred to receive further care, yet only 3 patients were referred for rehabilitative services. Furthermore, the data suggest that patients sustaining comorbid injuries in addition to TBI may be predisposed to worse outcomes. Improvements in documentation of military patients may improve knowledge of TBI and further identify potential variables or treatments that may affect prognosis. The increased survivability from TBI also highlights the need for additional research expenditure in the field of neurorehabilitation specifically.

Provider Knowledge Gaps in HIV PrEP Affect Practice Patterns in the US Navy.

INTRODUCTION: Although HIV pre-exposure prophylaxis (PrEP) is available at no cost to personnel in the United States (U.S.) military, uptake has been lower than expected. An online survey was conducted assessing current knowledge, perceptions, and attitudes of primary care providers in the U.S. Navy. MATERIALS AND METHODS: A cross-sectional anonymous online survey was conducted among U.S. Navy healthcare providers in active service. Providers' demographics, medical practice and PrEP experience, and attitudes regarding PrEP were assessed by self-rated PrEP knowledge. RESULTS: Greater than half of respondents reported being knowledgeable about PrEP and a majority (78%) supported the provision of PrEP in the military health system. However, only 19% had ever prescribed PrEP. Self-reports of having been questioned by a patient about PrEP, having high levels of comfort discussing sexual risk behaviors, and being in a specialty of infectious disease, occupational health, or preventive medicine were associated with increased knowledge about PrEP. The more knowledgeable a provider was about PrEP, the more likely they were to prescribe it (29% vs. 6%). CONCLUSIONS: Although Navy providers were supportive of the provision of PrEP by the military, knowledge gaps remain. Training to address the knowledge deficit as well as improving sexual history taking are potential areas to target in implementing PrEP in primary care specialties.

2015 Department of Defense Health Related Behaviors Survey (HRBS).

The Health Related Behaviors Survey (HRBS) is the U.S. Department of Defense's flagship survey for understanding the health, health-related behaviors, and well-being of service members. In 2014, the Defense Health Agency asked the RAND Corporation to review previous iterations of the HRBS, update survey content, administer a revised version of the survey, and analyze data from the resulting 2015 HRBS of active-duty personnel, including those in the U.S. Air Force, Army, Marine Corps, Navy, and Coast Guard. This study details the methodology, sample demographics, and results from that survey in the following domains: health promotion and disease prevention; substance use; mental and emotional health; physical health and functional limitations; sexual behavior and health; sexual orientation, transgender identity, and health; and deployment experiences and health. The results presented here are intended to supplement data already collected by the Department of Defense and to inform policy initiatives to help improve the readiness, health, and well-being of the force.

Field Expedient Vasopressors During Aeromedical Evacuation: A Case Series from the Puerto Rico Disaster Response.

IntroductionEmergency physicians are using bolus-dose vasopressors to temporize hypotensive patients until more definitive blood pressure support can be established. Despite a paucity of clinical outcome data, emergency department applications are expanding into the prehospital setting. This series presents two cases of field expedient vasopressor use by emergency medicine providers for preflight stabilization during aeromedical evacuation to a hospital ship as part of the United States Navy disaster response in Puerto Rico. A critical approach and review of the literature are discussed.Case ReportTwo critically ill patients were managed in an austere environment as a result of the devastation from Hurricane Maria (Yabucoa, Puerto Rico; 2017). They both exhibited signs of respiratory distress, hemodynamic instability, and distributive shock requiring definitive airway management and hemodynamic support prior to aeromedical evacuation.DiscussionThe novel use of field expedient vasopressors prior to induction for rapid sequence intubation was successfully and safely employed in both cases. Both patients had multiple risk factors for peri-induction cardiac arrest given their presenting hemodynamics. Despite their illness severity, both patients were induced, transported, and ultimately admitted to the intensive care unit (ICU) in stable condition following administration of the field expedient vasopressors.Conclusion:Field expedient vasopressors were safely and effectively employed in an austere field environment during a disaster response. This case series contributes to the growing body of literature of safe bolus-dose vasopressor use by emergency physicians to temporize hypotensive patients in resource-constrained situations.
