Despite advancements in military medical treatment and evacuation, soldiers in austere environments remain vulnerable to disease and non-battle injury and may face prolonged evacuation before receiving definitive care. In particular, arranging care for a soldier presenting with a conditions that has a wide differential diagnosis, such as acute altered mental status (AMS), can be especially challenging. We highlight the case of an otherwise young, healthy U.S. Soldier serving in Indonesia, who presented with acute AMS concerning for undifferentiated infection. Subsequent workup at the receiving hospital following evacuation revealed Salmonella enterica infection, more commonly known as typhoid. However, even with clinical findings of typhoid encephalitis and initiation of empiric treatment, medical care proved challenging in the resource-limited local facilities, despite multiple escalations of care. Ultimately, the patient was evacuated to a tertiary facility in Singapore, where his condition improved, and 4 days after initial presentation the patient had no definitive findings of infections on lumbar puncture. This case not only highlights the threat of typhoid and other infectious diseases in modern operations but also the challenges of suboptimal medical care in both the prehospital and hospital settings when utilizing host nation facilities.

Background: In emergency casualty and evacuation situations, manual ventilation using self-inflating bags remains a critical skill; however, significant challenges exist in ensuring safety and effectiveness, since inaccurate manual ventilation is associated with life-threatening risks (e.g., gastric insufflation with aspiration, barotrauma, and reduced venous return). Methods: This study assessed the impact of audiovisual feedback from the bag-valve-mask (BVM) emergency narration guided instrument (BENGI), a handheld manual ventilation guidance device, on improving performance and safety, immediately and 2 weeks after, with no additional manual ventilation training. In a crossover manikin simulation study with 20 participants, BENGI immediately and significantly improved tidal volume and respiratory rate accuracy. Results: Intraand inter-participant variations were lower with BENGI, with Poincaré plot analysis showing improved performance that remained for at least 2 weeks following BENGI training. Conclusion: BENGI's audiovisual feedback improves manual immediately and persistently, making it invaluable for training and clinical use in diverse scenarios, from battlespace to civilian emergencies.

Herein, we present a simplified approach to prehospital mass casualty event (MASCAL) management called "Move, Treat, and Transport." Prior publications demonstrate a disconnect between MASCAL response training and actions taken during real-world incidents. Overly complex algorithms, infrequent training on their use, and chaotic events all contribute to the low utilization of formal triage systems in the real world. A review of published studies on prehospital MASCAL management and a recent series of military prehospital MASCAL responses highlight the need for an intuitive MASCAL management system that accounts for expected resource limitations and tactical constraints. "Move, Treat, and Transport" is a simple and pragmatic approach that emphasizes speed and efficiency of response; considers time, tactics, and scale of the event; and focuses on interventions and evacuation to definitive care if needed.

Building on our strategic framework and operational model, we will discuss findings from our ethnographic study entitled, "The Impact of Catastrophic Injury Exposure on Resilience in Special Operations Surgical Teams (SOST)." Our goal is to establish that medical-martial creativity supports Special Operation Forces (SOF) medics' ability to fluidly modulate pressure amid real-time military medical decision-making in austere environments. We will use qualitative quotes to explore how SOST medics express medical-martial creativity in support of unconventional resilience. We continue to highlight tactical engagement by using bag sets as a metaphor for understanding the practical performance of this social determinant. To achieve our goals, we will: 1) define the social determinant of medical-martial creativity and provide a brief background on creativity; 2) thematize various ways in which medical-martial creativity is optimized or degraded; and 3) relate tactical engagement with medical-martial creativity to our metaphor of bag sets. We conclude by gesturing to how medical-martial creativity enables SOF medics' ingenuity, which allows them to freely maneuver complex real-time decision-making to support SOF mission success.

Training needs of Special Operations Forces (SOF) medics were surveyed and new training initiatives have been created to meet their needs. SOF medics perform an array of medical procedures in austere environments with minimal supervision. Medical skills decay over time after initial training and the perceived training needs of active SOF medics were unclear. To fill this gap, active SOF medics (n=57) completed a survey that included confidence ratings and indications of whether additional training would make them more proficient in 70 medi cal knowledge and procedural skills, assembled into categories by a panel of experts (airway, trauma, neuro, differential di agnosis, administrative, infection, critical care, environmental, other). Data were analyzed with analysis of variance (ANOVA) and nonparametric statistics at P<.05. Confidence was highest in the trauma, administrative, and airway categories, and lowest in the infection, differential diagnosis, and neuro categories (P<.05 or less). Categories indicating the greatest need for additional training were environmental and critical care, while those indicating lowest need were the airway and trauma categories (P≤.05). Additional training was endorsed by >75% of participants in each category. SOF medics also wanted additional training in all areas, preferably hands-on with live patients in realistic scenarios, taught by experienced medics. Findings highlight the training needs of SOF medics and demonstrate the value of bottom-up feedback toward op timizing sustainment training. Based on present findings, two TACMED (Tactical Medicine) Divisions at the SOF Echelon III level were created to meet the sustainment training needs of SOF medics

Rapid and effective tourniquet application is crucial in life-threatening limb hemorrhage to minimize mortality. However, the widespread availability of counterfeit tourniquets is a growing concern, as these devices may lack essential quality control measures, potentially compromising patient care. We describe one case where the delayed mechanical failure of a Combat Application Tourniquet (CAT)-like tourniquet caused the death of a Ukrainian soldier during evacuation to an urban trauma center. In April 2022, a 19-year-old male underwent a bilateral below-the-knee amputation from an antipersonnel landmine. Massive hemorrhage prompted the use of bilateral CAT-like tourniquets. During transportation, the right tourniquet's windlass broke, resulting in a brisk hemorrhage. Due to the high patient-to-healthcare-personnel ratio, the bleeding remained unaddressed for an unknown amount of time, resulting in death from hemorrhagic shock. This study underscores the need for robust quality control measures and the establishment of strict regulations against deploying counterfeit tourniquets to avoid preventable deaths.

Biting sandflies are known for transmitting leishmaniasis, but sandflies also transmit sandfly fever viruses that may disrupt military operations. Sandfly fever is caused by serotypes of the Phlebovirus genus (primarily the Naples, Sicilian, or Toscana serotypes). The illness is known colloquially as "three-day fever" and "papataci fever." The clinical course of the disease normally spans about 3 days, with patients exhibiting a prodromal phase consisting of fatigue, chills, abdominal pain, and possibly facial flushing and tachycardia. Disease onset is marked by hyperpyrexia, myalgia, and arthralgia. The incubation period is typically 3-5 days, with viremia in humans lasting typically less than 1 week. This manuscript describes sandfly appearance, behavior, and geographic distribution. It then lists comparable diseases for differential diagnosis. Finally, as no vaccine exists for the sandfly virus, it concludes with steps for preparation and prevention to prevent outbreaks from disrupting military operations.

Background: The Military Health System is a unique subsector within the nation's Graduate Medical Education (GME), with a different incentive structure for specialty selection for military medical students compared with their civilian counterparts. Changes by the Defense Health Agency (DHA) in 2017 emphasized a shift in military GME to training "operational" medical specialties. This study sought to gain insight into military medical students' reactions to the 2017 DHA transition by examining whether students continued to select "operational" specialties at similar rates as well as whether students remained satisfied with attending medical school. Methods: We performed a retrospective analysis of Uniformed Services University (USU) post-match students from 2015 to 2020 using anonymized data from the Association of American Medical Colleges (AAMC) Graduation Questionnaire, separated into pre-DHA (2015-2017) and post-DHA (2018-2020) transition groups. Results: Regarding both intent to practice an operational specialty and satisfaction with choosing medical school, there was no statistically significant difference between the preand post-DHA transition groups. Conclusions: Whether preor post-DHA transition, USU medical students demonstrated similar preferences for operational specialties as well as similar levels of satisfaction with medical school attendance, suggesting that this transition may not significantly influence medical students' career preferences nor blunt their desire to enter military medicine.

Introduction: A systematic radiological examination is needed for military airborne troops in order to detect subclinical medical contraindications for airborne training. Many potential recruits are excluded because of scoliosis, kyphosis, or spondylolisthesis. This study aimed to determine whether complementary radiological assessment excludes too many recruits and whether medical standards might be lowered without increasing medical risk to appointees. Methods: This retrospective, epidemiological, cross-sectional single-center study spanned 5 years at the French paratroopers' initial training center. We analyzed all medical files and full-spine X-ray results of all enlisted troops during this period. Secondary evaluation by an orthopedic surgeon enabled 23 enlisted personnel, deemed medically unacceptable because of X-ray findings, to be given waivers for airborne training. A follow-up review of their 23 files was conducted to determine whether static-line parachute jumps were hazardous to those who were initially declared medically unacceptable. Results: Of the 3,993 full-spine X-rays, 67.5% (2,695) were described as having normal alignment and structure; 21.8% (871) had lateral spinal deviation; and 10.7% (427) had scoliosis. Sixty-six recruits (1.6%) were deemed unfit because of findings that did not meet the standard on the fullspine X-ray: 53 enlisted personnel had scoliosis greater than 15°, and 13 had spondylolisthesis (grade II or III). Of the 23 patients granted waivers, 82.3% with scoliosis (14) and all patients with kyphosis had not declared any back pain after 5 years. Conclusion: The findings, supported by a literature review of foreign military data, suggest that spondylolisthesis above grade I and low back pain are more significant than scoliosis and kyphosis for establishing airborne standards.

Introduction: Mass casualty events (MASCALs) in the combat environment, which involve large numbers of casualties that overwhelm immediately available resources, are fundamentally chaotic and dynamic and inherently dangerous. Formal triage systems use diagnostic algorithms, colored markers, and four or more named categories. We hypothesized that formal triage systems are inadequately trained and practiced and too complex to successfully implement in true MASCAL events. This retrospective analysis evaluates the real-world application of triage systems in prehospital military MASCALs and other aspects of MASCAL management. Methods: We surveyed Special Operations Forces (SOF) medics known to us who have participated in military prehospital MASCALs and analyzed them. Aggregated data describing the scope of the incidents, the use of formal triage algorithms and colored markers, the number of categories, and the interventions on scene were analyzed using descriptive statistics, and lessons learned were consolidated. Results: From 1996 to 2022 we identified 29 MASCALs that were managed by military medics in the prehospital setting. There was a median of three providers (range 1-85) and 15 casualties (range 6-519) per event. Four or more formal triage categories were used in only one event. Colored markers and formal algorithms were not used. Life-saving interventions were performed in 27 of 29 (93%) missions and blood transfusions were performed in four (17%) MASCALs. The top lessons learned were: 1) security and accountability are cornerstones of MASCAL management; 2) casualty movement is a priority; 3) intuitive triage categories are the default; 4) life-saving interventions are performed as time and tactics permit. Conclusion: Formal triage systems requiring the use of diagnostic algorithms, colored tags, and four or five categories are seldom implemented in real-world military prehospital MASCAL management. The training of field triage should be simplified and pragmatic, as exemplified by these instances.

Background: The resuscitative endovascular balloon occlusion of the aorta (REBOA) technique controls abdominal, pelvic, junctional, and postpartum hemorrhage via aortic endoclamping. There are no protocols or clear indications guiding REBOA use in a two-tiered prehospital emergency medical system, as found in France. We conducted a Delphi study to clarify the indications and contraindications for REBOA application in such a system. Methods: We performed a Delphi study in three rounds with an international group of doctors with REBOA expertise and clinical experience (members of the EndoVascular and Trauma Management Society). Based on the consensus answers, complemented by existing data in the literature, we developed a protocol for REBOA use in a medicalized prehospital setting. Results: We identified 10 questions that were not answered in the literature and submitted them to 21 experts. Over three rounds, consensus was reached on these 10 questions. The most important ones were "In your opinion, in a hemorrhagic patient, vascularly well-filled and whose hemodynamics remain unstable with 3mg/h of norepinephrine, should we inflate a REBOA to prevent the patient's death and get them to the operating room alive?" and "In the case of REBOA placement (zone I) in the prehospital setting, would you agree that the maximum occlusion duration is approximately 30 minutes, with a partial or intermittent occlusion when possible?" Conclusion: We propose a protocol for REBOA use in a medicalized prehospital setting. This protocol clarifies that hemorrhagic shock, despite a noradrenaline (also known as norepinephrine) dose of 0.6µg/kg/min, is considered too serious for the patient to be transported to the trauma center without REBOA. Moreover, it clarifies that a zone 1 REBOA should be inflated for maximum 30 minutes and with a partial occlusion strategy, if possible. This protocol should be updated based on feedback following the establishment of prehospital REBOA and large randomized studies.

Lumbar paraspinal muscle compartment syndrome is an uncommon, rapidly progressive, and potentially devastating injury with fewer than 40 cases reported in the literature. It initially mimics nonemergent causes of low back pain, disproportionately affects young men, and is most often secondary to acute physical exertion. The disease process is commonly associated with rhabdomyolysis. Diagnostic tools include physical examination, measurement of lactate and creatine kinase levels, MRI, and direct compartment pressure measurement. While medical and nonoperative management strategies have been explored, the gold standard for treatment is emergent lumbar fasciotomy. Opioid and non-steroidal pain management, as well as physical therapy, are the mainstays of post-treatment recovery, with many surgical patients reporting complete symptom resolution at long-term follow-up. This article discusses the case of a 27-year-old, male, active-duty, Special Operations Aviation Soldier who presented to the emergency department and was found to have lumbar paraspinal muscle compartment syndrome.
