Mastering multicasualty trauma care with the Trauma Non-technical Skills Scale.

Multicasualty events present complex medical challenges. This is the first study to investigate the role of nontechnical skills in prehospital multicasualty trauma care. We assessed the feasibility of using the Trauma Nontechnical Skills Scale (T-NOTECHS) instrument, which has not yet been investigated to evaluate these scenarios. We conducted an observational study involving military medical teams with Israel Defense Forces Military Trauma Life Support training to assess the T-NOTECHS' utility in predicting prehospital medical team performance during multicasualty event simulations. These teams were selected from a pool of qualified military Advanced Life Support providers. Simulations were conducted in a dedicated facility resembling a field setting, with video recordings to ensure data accuracy. Teams faced a single multicasualty scenario, assessed by two instructors, and were evaluated using a 37-item checklist. The T-NOTECHS scores were analyzed using regression models to predict simulation performance. We included 27 teams for analysis, led by 28% physicians and 72% paramedics. Interrater reliability for simulation performance and T-NOTECHS scores showed good agreement. Overall T-NOTECHS scores were positively correlated with simulation performance scores ( R = 0.546, p < 0.001). Each T-NOTECHS domain correlated with simulation performance. The Communication and Interaction domain explained a unique part of the variance ( β = 0.406, p = 0.047). Assessment and Decision Making had the highest correlation ( R = 0.535, p < 0.001). These domains significantly predicted specific items on the simulation performance checklist. Cooperation and Resource Management showed the least correlation with checklist items. This study confirms the T-NOTECHS' reliability in predicting prehospital trauma team performance during multicasualty scenarios. Key nontechnical skills, especially Communication and Interaction, and Assessment and Decision Making, play vital roles. These findings underscore the importance of training in these skills to enhance trauma care in such scenarios, offering valuable insights for medical team preparation.

Prehospital transfusion of labile blood product using intraosseous perfusion with multi-lumen extender: Why not?

French prehospital military medical teams are provided with labile blood products to effectively address hemorrhagic shock. In combat environment, standard good medical practice may limit efficacy of therapeutic goals regarding damage control resuscitation. We present here a case report describing the management of a soldier heavily wounded during a helicopter forward medical evacuation in Sahel region. We report the challenge encountered by medical team using only a humeral intraosseous route available due to severity of lesions and challenging environment. In this configuration, multi-lumen extender enabled transfusion of two units of packed red blood cells and two units of plasma, and analgesia while limiting manipulation and dislodgment of the fragile intraosseous route. This situation, outside of usual good medical practice, raises issues of hemolysis, physicochemical compability of drugs and blood products, and consequences on flow rate reduction. With this case, we emphasize the benefit of multi-lumen extender associated with intraosseous route for early management of heavy casualties in harsh prehospital environment. Literature suggests that hemolysis and physicochemical compability should remain limited. The main issue of this setting consists of flow reduction and can be addressed by prioritizing humeral route, and using counter pressure cuffs, until a second peripheral or central line is available and management can resume without the need for multi-lumen extender.

Improved Casualty Depiction System for Simulated Mass Casualty Exercises.

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. 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. 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. 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.

Performance of far forward iceless blood storage containers in controlled cold environments.

The Golden Hour Box (GHB), an iceless blood container designed for transfusion closest to the point of injury, is used by military medical teams in remote damage control resuscitation. While its performance is well-established in hot environments, it remains underexplored in cold conditions, a significant consideration in emerging global conflict zones. Four GHBs were preconditioned at +4°C or +18°C for 8 h and subsequently exposed to controlled laboratory simulated temperatures of -5, -15, and -25°C for 100 h. The study focused on their capability to maintain an internal temperature between +2 and +6°C, the recommended range for red blood cells unit storage and transport, using calibrated sensors for precise monitoring. When exposed to negative Celsius temperatures, GHBs showed varied performance depending on preconditioning temperatures. When preconditioned at +4°C, GHBs maintained an internal temperature within the target range (+2 to +6°C) for 100 h at -5°C, 52 ± 1 h at -15°C, and 29 ± 4 h at -25°C. In contrast, the internal temperature of GHBs preconditioned at +18°C exceeded this range in less than 30 min, then dropped below 2°C more rapidly than those preconditioned at +4°C, occurring within 20 ± 2 h at -15 and 13 ± 1 h at -25°C. The GHB, when properly preconditioned, effectively maintains internal temperatures suitable for blood product transport in extreme cold. Future research, including analyses of blood performances, is still needed to validate these results in more realistic operational conditions for use in cold environments.

Optimizing Care for Military Women: The Value of the Dual-Certified Family and Women's Health Nurse Practitioner.

The number of women in the military has more than tripled over the past 50 years, increasing from 5% in the 1970s to 17% in 2023, making them essential for global health engagement and military operations. Provider competence and confidence are barriers to the consistent availability of preventive, gynecologic, and reproductive services for women across service locations and duty platforms. The Defense Health Board recommends standardizing services and improving the availability and scope of services for women at every point of care. In direct conflict with these recommendations, however, is a congressional call for a drawdown of medical forces, which creates a need for operationally trained clinicians with a broad skill set including comprehensive care for women. Advanced practice registered nurses, such as family and women's health nurse practitioners, are key assets to fill this gap on military medical health-care teams. At the request of the U.S. Air Force, the Graduate School of Nursing at the Uniformed Services University began offering a Women's Health Nurse Practitioner (WHNP) program in 2014. The WHNP curriculum was layered onto the existing Family Nurse Practitioner program so that Family Nurse Practitioner students receive enhanced education in women's health and WHNP students are prepared to meet the holistic, primary care needs of patients across the lifespan in addition to caring for women with obstetric and urogenital health concerns. This article highlights the value of dual-certified Family Nurse Practitioners and WHNPs in the military health-care system. These Uniformed Services University alumni are uniquely prepared to provide comprehensive primary and specialty care for female warfighters across the lifecycle from stable, well-resourced duty stations to austere, operational settings or deployment platforms.

Specificity of tactical rescue in combat operations

The article contains basic information defining tactical rescue in combat operations.Starting from the genesis, following issues developing the specificity of this issue, i.e., the operationof military medical teams divided into modules and zones of providing assistance depending on thetactical situation, which determine priorities in providing assistance to the wounded. In addition, theprocedure for relieving pain with analgesics was characterised, depending on the conditions and thepossibilities in tactical conditions. The included issues may be helpful in the directional education ofsoldiers on the subject matter. The determinant of creation of the article is to make the reader awareof the above issue and the specificity of the tactical rescuer’s actions on the battlefield. Serious injuriesand deaths occur during combat operations. Thanks to appropriate conservative actions resulting fromthe soldier’s knowledge, a large number of fatal cases can be avoided. That is why knowledge in thisarea is so important at every level of a military unit.Keywords: tactical rescue, combat operations, patrol operations, battlefield, providing assistance tothe injured

Application of a Near-infrared Spectroscope by an Extreme Forward Medical Team for the Triage of Casualties With Traumatic Brain Injury.

During deployment of military medical teams similarly to prehospital practice, without immediate computed tomography scan access, identifying patients requiring neuro-specific care to manage pragmatic triage proves crucial. We assessed the contribution of this portable near-infrared spectroscope (NIRS) handheld device, Infrascanner Model 2000 (InfraScan Inc.; Philadelphia, PA), to screen patients suspected to require specific neurosurgical care. This single-center retrospective analysis was based on the data from the medical records of the traumatic brain injured patients. We analyzed all the patients strictly over 18 years old presenting a clinical history of traumatic brain injury (TBI) with a Glasgow Coma Scale (GCS) < 15. Thirty-seven medical records of patients admitted for TBI met the inclusion criteria for our analysis. The median GCS was 9 [3-14]. Eight patients (21.6%) underwent neurosurgery and 25 (67.6%) required intensive care unit (ICU) admission, after initial assessment and resuscitation. The NIRS was the most sensible to detect intracranial hematoma (n = 21), intracranial hematoma leading to surgery (n = 8), and intracranial hematoma leading to admission in ICU (n = 25). Its negative predictive value was 100% regarding hematomas leading to surgery. False-positive results were encountered in 10 cases (27.0%). Excluding cases harboring confounding extracranial hematomas, parietal area was still the most represented (n = 3). The NIRS was relevant to detect hematoma leading to prompt surgery in our study. The lack of specificity in a nonselected cohort of patients underlines the need to associate simple clinical feature such as neurological deficit and NIRS results to perform rational triage.

Building a sustainable Mil-Civ partnership to ensure a ready medical force: A single partnership site's experience.

One of the challenges in military medicine is ensuring that the medical force deployed to the theater of combat operations is prepared to perform life, limb, and eyesight saving care at a level of care comparable to our top civilian Level I trauma centers. There is increasingly more evidence demonstrating that the majority of military physicians are not exposed to trauma or combat casualty care-relevant surgical cases on a consistent basis in their daily practice at their garrison military treatment facility (MTF). To prevent this widening skills and experience gap from become more of a reality, the 2017 National Defense Authorization Act called for the expansion of military and civilian (Mil-Civ) medical partnerships, working toward embedding military medical providers and surgical teams in busy civilian trauma centers. Vanderbilt University Medical Center is one of the busiest trauma centers in the country and being in close proximity to the local MTF at Fort Campbell, KY, it is primed to become one of the premier Mil-Civ partnerships. Creating a strategy that builds the partnership in a calculated and stepwise fashion through multiple avenues with centralized leadership has resulted in the early success of the program. However, Vanderbilt University Medical Center is not immune to challenges similar to those at other Mil-Civ partnerships, but only by sharing best practices can we continue to make progress.

High Success Rate of Prehospital and En Route Cricothyroidotomy Performed in the Israel Defense Forces: 20 Years of Experience.

Securing the airway is a crucial stage of trauma care. Cricothyroidotomy (CRIC) is often addressed as a salvage procedure in complicated cases or following a failed endotracheal intubation (ETI). Nevertheless, it is a very important skill in prehospital settings, such as on the battlefield. This study aimed to review the Israel Defense Forces (IDF) experience with CRIC over the past two decades. The IDF Trauma Registry (IDF-TR) holds data on all trauma casualties (civilian and military) cared for by military medical teams since 1997. Data of all casualties treated by IDF from 1998 through 2018 were extracted and analyzed to identify all patients who underwent CRIC procedures.Variables describing the incident scenario, patient's characteristics, injury pattern, treatment, and outcome were extracted. The success rate of the procedure was described, and selected variables were further analyzed and compared using the Fisher's-exact test to identify their effect on the success and failure rates. Odds Ratio (OR) was further calculated for the effect of different body part involvement on success and for the mortality after failed ETI. One hundred fifty-three casualties on which a CRIC attempt was made were identified from the IDF-TR records. The overall success rate of CRIC was reported at 88%. In patients who underwent one or two attempts, the success rate was 86%. No difference was found across providers (physician versus paramedic). The CRIC success rates for casualties with and without head trauma were 80% and 92%, respectively (P = .06). Overall mortality was 33%. This study shows that CRIC is of merit in airway management as it has shown to have consistently high success rates throughout different levels of training, injuries, and previous attempts with ETI. Care providers should be encouraged to retain and develop this skill as part of their tool box.

Situational Awareness: Forecasting Successful Military Medical Teams.

Military healthcare providers working in military interprofessional healthcare teams (MIHTs) require situational awareness (SA) to ensure safe and efficacious patient care. This study aimed to explore SA in MIHTs to understand how SA can be reinforced and maintained in MIHTs. The research team set out to answer two questions: "What aspects of individual and team SA are particularly important for MIHTs?" and "How can we enable military healthcare providers to be effective MIHTs members with robust SA?". This study used Grounded Theory methodology collecting perspectives from 30 study participants from various backgrounds, including 11 different healthcare professions from the U.S. Army, Air Force, and Navy. Each study participant had experiences participating in, leading one, or leading many MIHTs. Data were collected in three cycles and analyzed within each cycle until saturation was reached. Five themes were robustly represented in the data set regarding SA: (1) contextually informed adaptability, (2) readiness, (3) trust, (4) communication, and (5) mission focus. The urgency often faced by MIHTs brings SA and the principles that underpin SA into sharper focus. The SA themes identified in this research may provide insight into training effectiveness, team strengths and weaknesses, and team performance.

Helicopter Rescue Missions for Emergency Medical Aid at Sea: A New Assignment for the French Military Medical Service?

Historically in charge of the search and rescue of aircraft in distress alongside military aeronautical crews, the doctors and nurses of the French Military Medical Service (FMMS) also participate in helicopter rescue missions for emergency medical aid at sea off the French metropolitan coast. This public service mission is placed at the heart of force medicine because it can be transposed to external theaters of operations (OPEX). Recent changes in the regulation of medical aid at sea, in particular the creation in 2013 of maritime emergency mobile resuscitation services, initially weakened the role of the teams of the FMMS. However, their 2018 and 2019 activity report reflects the persistence of strong involvement. The "FMMS 2020" model, especially through its "openness" aspect, allows the FMMS the optimal conditions to maintain its position as a key player in this field, particularly through the development of institutional partnerships with the public health service. Associated with their mastery of the air-maritime environment, strengthening the skills in emergency medicine of the military medical teams in charge of this mission appears to be 1 of the main measures ensuring the achievement of this objective and a high quality of care for patients.

Highly realistic cadaveric trauma simulation of the multiply injured battlefield casualty: an international, multidisciplinary exercise in far-forward surgical management.

We designed an ultra-high-fidelity military cadaveric surgical simulation course to train military medical teams for specific battlefield injuries. Our aim was to deliver a highly realistic, immersive simulation training experience, teaching both technical and non-technical skills necessary for the management of war-injuries in the austere environment of a far forward surgical facility. We designed an educational cohort study around the course to measure its learning impact. 25 personnel participated in 15 non-continuous hours of simulation that included 12 patient scenarios. Participants were given previously piloted questionnaires pre- and post-simulation to assess their confidence with managing battlefield injuries by body area, their views on the realism of the simulation, and their perceptions of training benefit. All questions were assessed using a Likert scale of 1-10 (10=best). The response rate for complete questionnaires was 95%. Baseline confidence scores were; abdomen (5.5), pelvis (5.7), chest (6.2), airway (6.3), extremity (7.3). Confidence gains following training were; abdomen (+1.7), pelvis (+ 1.6), chest (+1.6), airway (+1.2), extremity (+0.8). The most realistic aspects of the simulation were; injury replication (9.1), the cadaver as a multiply injured casualty (9.1) and the multidisciplinary team (9.2). The mean ratings for technical and non-technical skill acquisition were 9.1 and 9.0 respectively. Cadaveric simulation was reported to be ideal for learning military medical skills (9.3), and participants strongly recommended that provision should be increased (9.7). We have demonstrated an ability to recreate highly realistic injuries in an ultra-high-fidelity simulation of a multiply injured military casualty. There was a measurable increase in confidence for both technical skills in all major body areas, and non-technical skills. Multinational and multidisciplinary working strongly enhanced learning.

It provides some additional comments on the national protocol including disease name, virus origin, population susceptibility, interpretation of serum-specific antibody test results, evaluation of outbreak outcome and so on.

The effects of military-wide introduction of advanced tourniquets in the Israel Defense Forces

BackgroundEarly application of tourniquets has reduced injury death rates. At the end of 2013, the Israel Defense Forces Medical Corps completed a military-wide introduction of the Combat Application Tourniquet as the standard-issued tourniquet. The accompanying clinical practice guideline encouraged combat soldiers and medical teams towards a liberal use of tourniquets for extremity injuries, even when in doubt. ObjectivesThis study aimed to assess the effects of the wide introduction of advanced tourniquets on the rate of tourniquet applications, the type of tourniquet applied, and the differences in hospitalisation outcomes following the introduction. MethodsThe study population was composed of hospitalised military casualties with an extremity injury treated by military medical teams between 2006 and 2015. Prehospital data were extracted from the Israel Defense Forces Trauma Registry and matched to corresponding hospital data from the Israeli National Trauma Registry. Two periods were compared: 2006–2013 "pre-intervention period" and 2014–2015 "post-intervention period". ResultsA total of 1,578 casualties were recorded during the study period. Of these, 320 (20.3%) occurred between 2014–2015. Characteristics of casualties in the post-intervention period were similar to those in the pre-intervention period including the rate of traumatic amputations (2.5% vs 2.2%, p = 0.93) and Injury Severity Score of 16 or above (12.8% vs 14.9%, p = 0.40). The rate of tourniquet application was more than four-fold in the post-intervention period compared to the pre-intervention period (22.8% vs 5.5%, p < 0.001). Nevertheless, rates of in-hospital amputations (1.6% vs 1.6%, p = 1.00) and death (0.9% vs 1.3%, p = 0.53) were similar in the two periods. ConclusionFollowing the IDF military-wide introduction of advanced tourniquets, the tourniquet application rate rose sharply, the use of old tourniquets ceased over time, and in-hospital amputation rate did not increase. These findings suggest that the awareness for haemorrhage control using advanced tourniquets rose.

Fixed Wing Tactical Aircraft for Air Medical Evacuation in Sahel

ObjectiveThe medical support of military operations over a 5 million km2 area in the Sahel-Saharan strip has justified the use of a medical fixed wing aircraft. Two CASA CN 235 aircraft currently perform medical evacuation (medevac) from the point of injury to forward surgical structures and then to the international airport before strategic medevac to France. MethodsA retrospective observational study including all flights performed from January 2013 to December 2017 by the medical CASA located in Mali. ResultsThree thousand three flight hours were achieved. Four hundred twenty-four medevacs were performed for 898 patients. Seventy-five percent were evacuated from forward surgical structures. Their initial categorization included 10% Alpha, 23% Bravo, and 67% Charlie. Mechanical ventilation was performed for 5%; 34.5% had common medical or surgical pathologies, 34.2% were combat casualties mostly by explosion, and 18.7% were nonbattle injuries. No difficulties related to the aeronautical environment were reported by the teams. ConclusionTactical medevac with fixed wing aircraft has become a crucial link in the French medical evacuation chain in remote areas. Military emergency medical teams were able to provide in-flight intensive care before and after damage control surgery. Discussions are underway to consider possible doctrinal and logistical evolutions.

Post-traumatic stress disorder in disaster workers and emergency personnel

The problem of stress and disorders occurring in a team (traumatic stress) is the subject of numerous scientific studies in relation to victims of traffic accidents, rape, acts of terrorism and war. The research on this overlooked subject concerns specific professions such as the military, police, fire brigades and rescue medical teams. The aim of this research is to analyze the mechanisms leading to increased susceptibility to stress and predisposing factors for the occurrence of post-traumatic stress disorder and its specific features among people working in emergency medical teams.

Slides in the Tray: How Fire Crews Enable Members to Borrow Experiences

Experiential learning is essential for many high-performing teams, yet there are also challenges to its incorporation into team training. Using an interpretivist lens, this study explores how members of wildfire crews are encouraged to appropriate the experiences of their teammates to improve team process. First, we offer a tripartite argument for how experiential learning is inhibited. Then, based on our findings, we argue that a key practice of critical teamwork is the ability of team members to “borrow” experiences or learn from the experiences of others. We examine how firefighters interpret the concept of experience; the delineation between experiences and personal experiences was often blurred, as some firefighters spoke about experience as something that could be gained through activities that are not specifically firefighting. We delineate five training interactions through which firefighters are encouraged to appropriate the experiences of their colleagues. We then discuss how this extends the principles of the Nested Phase Model for critical teams and suggest areas for future research. These findings have implications for all types of critical teams—including military units and medical teams—as well as high-reliability organizations.

Successful implementation of thirty five major orthopaedic procedures under poor conditions after the two thousand and fifteen Nepal earthquake.

After receiving the 25 April 2015 Nepal earthquake relief mission, a fully self-sufficient Rescue Center of Trauma set up quickly in downtown Kathmandu by Chengdu Military Medical Team of PLA P. R. China. The medical team consisted of 68 members and 40 tons of supplies, which was equivalent to a small hospital. The medical area and living area were constructed with tents. Operating areas were converted from eight simple bungalows. The main purpose of the Rescue Center of Trauma was to save those earthquake survivors who needed surgery. From 30 April to 10 May, 35 cases of orthopaedic internal fixation and external fixation operations were completed in the Rescue Center of Trauma. Surgery involved a total of 27 patients. All of the 27 orthopaedic surgery patients received treatment without any serious complications, including internal fixation failure, infection, amputation, limb deformities, limb dysfunction, or skin necrosis. Trauma infection rates are usually higher after an earthquake. Due to poor conditions, implementation of orthopaedic surgery at a field hospital is limited due to a lack of blood, equipment, and drugs. Infection control remains a key determinant of the success of surgery. Effective measures to control infection include strict environmental disinfection, extending the sterilizing time of fixation devices and supplies, doubling the number and time of washing and disinfection, and rational use of antibiotics based on past experience.
