A trauma expert consensus: Capabilities are required early to improve survivability from traumatic injury.

BACKGROUND: Mortality reviews examine US military fatalities resulting from traumatic injuries during combat operations. These reviews are essential to the evolution of the military trauma system to improve individual, unit, and system-level trauma care delivery and inform trauma system protocols and guidelines. This study identifies specific prehospital and hospital interventions with the potential to provide survival benefits. METHODS: US Special Operations Command fatalities with battle injuries deemed potentially survivable (2001-2021) were extracted from previous mortality reviews. A military trauma review panel consisting of trauma surgeons, forensic pathologists, and prehospital and emergency medicine specialists conducted a methodical review to identify prehospital, hospital, and resuscitation interventions (e.g., laparotomy, blood transfusion) with the potential to have provided a survival benefit. RESULTS: Of 388 US Special Operations Command battle-injured fatalities, 100 were deemed potentially survivable. Of these (median age, 29 years; all male), 76.0% were injured in Afghanistan, and 75% died prehospital. Gunshot wounds were in 62.0%, followed by blast injury (37%), and blunt force injury (1.0%). Most had a Maximum Abbreviated Injury Scale severity classified as 4 (severe) (55.0%) and 5 (critical) (41.0%). The panel recommended 433 interventions (prehospital, 188; hospital, 315). The most recommended prehospital intervention was blood transfusion (95%), followed by finger/tube thoracostomy (47%). The most common hospital recommendations were thoracotomy and definitive vascular repair. Whole blood transfusion was assessed for each fatality: 74% would have required ≥10 U of blood, 20% would have required 5 to 10 U, 1% would have required 1 to 4 U, and 5% would not have required blood products to impact survival. Five may have benefited from a prehospital laparotomy. CONCLUSION: This study systematically identified capabilities needed to provide a survival benefit and examined interventions needed to inform trauma system efforts along the continuum of care. The determination was that blood transfusion and massive transfusion shortly after traumatic injury would impact survival the most. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level V.

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

BACKGROUND: 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. METHODS: 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. RESULTS: 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 ( ß = 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. CONCLUSION: 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.

Family Physician's Satisfaction Report: Military 2021 vs. Civilian 2020 and 2022.

INTRODUCTION: In the Medscape 2020 Compensation Report, family physicians ranked low for feeling fairly compensated, choosing their specialty again and choosing medicine again. However, the Medscape data may not represent military family physicians. METHODS: A large survey was emailed to 2,562 military family physicians via a military professional organization list-serve from February to April 2021. The inquiry included 6 statements pertaining to professional satisfaction. The main outcome measures were proportions of "agree" and "strongly agree." The proportions were compared to the Medscape Compensation Report 2020 and 2022. Statistical analysis was completed with a two-tailed Z-score for 2 populations. RESULTS: Sixty-one percent of military family physicians feel fairly compensated compared to 54% of civilian family physicians in 2020 and 55% in 2022 (P = .065, .119). Eighty-six percent of military family physicians would reselect medicine compared to 74% of civilian family physicians in 2020 and 73% in 2022 (P < .001 for both). Eighty percent of military family physicians would reselect their specialty again compared to 70% of civilians in 2020 and 68% in 2022 (P = .004, P = .001, respectively). CONCLUSIONS: Military family physicians were more likely to choose medicine generally and family medicine specifically again. Military family physicians and civilian family physicians do not statistically differ in feeling fairly compensated. A strong majority of military family physicians are satisfied with their military-sponsored medical education.

Putting the ready in readiness: A post hoc analysis of surgeon performance during a military mass casualty situation in Afghanistan.

BACKGROUND: All military surgeons must maintain trauma capabilities for expeditionary care contexts, yet most are not trauma specialists. Maintaining clinical readiness for trauma and mass casualty care is a significant challenge for military and civilian surgeons. We examined the effect of a prescribed clinical readiness program for expeditionary trauma care on the surgical performance of 12 surgeons during a 60-patient mass-casualty situation (MASCAL). METHODS: The sample included orthopedic (four) and general surgeons (eight) who cared for MASCAL victims at Hamad Karzai International Airport, Kabul, Afghanistan, on August 26, 2021. One orthopedic and two general surgeons had prior deployment experience. The prescribed program included three primary measures of clinical readiness: 1, expeditionary knowledge (examination score); 2, procedural skills competencies (performance assessment score); and 3, clinical activity (operative practice profile metric). Data were attained from program records for each surgeon in the sample. Each of the 60 patient cases was reviewed and rated (performance score) by the Joint Trauma System's Performance Improvement Branch, a military-wide performance improvement organization. All scores were normalized to facilitate direct comparisons using effect size calculations between each predeployment measure and MASCAL surgical care. RESULTS: Predeployment knowledge and clinical activity measures met program benchmarks. Baseline predeployment procedural skills competency scores did not meet program benchmarks; however, those gaps were closed through retraining, ensuring all surgeons met or exceeded the program benchmarks predeployment. There were very large effect sizes (Cohen's d ) between all program measures and surgical care score, confirming the relationship between the program measures and MASCAL trauma care provided by the 12 surgeons. CONCLUSION: The prescribed program measures ensured that all surgeons achieved predeployment performance benchmarks and provided high-quality trauma care to our nation's service members. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

The Tägerwilen II report: Recommendations from the NATO Prehospital Care Improvement Initiative Task Force.

BACKGROUND: The Committee of the Chiefs of Military Medical Services (COMEDS) initiated the Prehospital Care Improvement Initiative Task Force (PHCII TF) to advise on how to improve prehospital care within NATO nations. The Task Force consisted of the NATO Military Health Care Working Group and its subordinated expert panels, including the Blood Panel, the Emergency Medicine Panel and the Special Operations Forces Medicine Panel. METHOD: The PHCII TF identified four key prehospital care themes for exploration: 1) Tactical Casualty Care, 2) Blood Far Forward), 3) Forward Surgical Capabilities), and 4) Prolonged Casualty Care. A consensus experimentation workshop explored the four themes, utilizing a modified Delphi technique and Utstein rotations during syndicate work, resulting in 83 consensus statements. The consensus statements were further evaluated on six criteria: actionable, measurable, urgent, interoperability, low risk/threat and impact. RESULTS: The 83 consensus statements, when weighted against the six criteria, resulted in 15 recommendations, focusing on standardization of training, ensuring provision of evidence-based practices and removing legislative barriers to improve prehospital care. CONCLUSION: The recommendations on these four themes reflect the most significant priorities in improving prehospital care, and must be incorporated in the on-going revision of NATO doctrine.

Department of Veterans Affairs (VA) and U.S. Department of Defense (DoD) guidelines for management of dyslipidemia and cardiovascular disease risk reduction: Putting evidence in context.

Atherosclerotic cardiovascular disease (ASCVD) remains the leading cause of morbidity and mortality in the United States (U.S.) and incurs significant cost to the healthcare system. Management of cholesterol remains central for ASCVD prevention and has been the focus of multiple national guidelines. In this review, we compare the American Heart Association (AHA)/American College of Cardiology (ACC) and the U.S. Department of Veterans Affairs (VA) and U.S. Department of Defense (DoD) Cholesterol guidelines. We review the evidence base that was used to generate recommendations focusing on 4 distinct themes: 1) the threshold of absolute 10-year ASCVD risk to start a clinician-patient discussion for the initiation of statin therapy in primary prevention patients; 2) the utility of coronary artery calcium score to guide clinician-patient risk discussion pertaining to the initiation of statin therapy for primary ASCVD prevention; 3) the use of moderate versus high-intensity statin therapy in patients with established ASCVD; and 4) the utility of ordering lipid panels after initiation or intensification of lipid lowering therapy to document efficacy and monitor adherence to lipid lowering therapy. We discuss why the VA/DoD and AHA/ACC may have reached different conclusions on these key issues.

Is tactical combat casualty care in terrorist attacks suitable for civilian first responders?

INTRODUCTION: Prehospital management of intentional mass casualty incidents is a unique challenge to Emergency Medical Services. Tactical Combat Casualty Care (TCCC) and the use of tourniquets for extremity hemorrhage have already proven to reduce mortality on the battlefield. This literature review aims to determine the place of these military concepts in a civilian high-threat prehospital setting. METHODS: The PubMed database was searched for articles published between January 1, 2000, and December 1, 2019, containing descriptions, discussions, or experiences of the application of tourniquets or other TCCC-based interventions in the civilian prehospital setting. Data extraction focused on identifying important common themes in the articles. RESULTS: Of the 286 identified articles, 30 were selected for inclusion. According to the Oxford Centre for Evidence-based Medicine Levels of Evidence, overall level of evidence was low. Most articles were observational, retrospective cohort studies without a nontourniquet control group. Outcome measures and variables were variably reported. Two articles specifically analyzed tourniquet use during high-threat situations, and three described their application by law enforcement personnel. Overall, tourniquets were found to be effective in stopping major limb bleeding. Reported mortality was low and related complications appeared to be infrequent. Only four articles mentioned the application of other TCCC-based maneuvers, such as airway and respiratory management. CONCLUSION: This literature review shows that tourniquets appear to be safe tools associated with few complications and might be effective in controlling major bleeding in civilian limb trauma. For example, during mass casualty incidents, their use could be justified. Training and equipping ambulance and police services to deal with massive bleeding could likewise improve interoperability and victim survival in a civilian high-threat prehospital setting. More qualitative research is needed to further evaluate the effects of hemorrhage control training for first responders on patient outcomes. Literature describing the application of other TCCC-based principles is limited, which makes it difficult to draw conclusions regarding their use in a civilian setting. LEVEL OF EVIDENCE: Systematic review, level III.

Joint replacements in the Canadian Armed Forces.

SUMMARY: There is currently no consensus on the appropriate sports and occupational restrictions for military service members with a joint replacement. Data from the United States show that 14% of military patients complete an operational deployment after the index surgery. No published data are available on arthroplasty in the militaries of other North Atlantic Treaty Organization countries. Research is needed to determine the appropriate medical employment limitations for Canadian Armed Forces members with a knee or hip replacement. Service members wanting to continue military service should be carefully screened to ensure that their duties do not compromise the longevity of the implant and that the risk of mission-threatening complications is minimal.

Effectiveness of a Primary Care-Based Pediatric Weight Management Program.

BACKGROUND: Childhood obesity is a growing epidemic of great concern for our nation, including pediatric populations treated at military treatment facilities. OBJECTIVE: This study aims to retrospectively evaluate the effectiveness of a primary care-based structured weight management program in a sample of pediatric patients with obesity at a military treatment facility. METHODS: This study was a retrospective chart review of patients enrolled in the All About Me Program (AAMP) from August 1, 2011, through July 10, 2012. Baseline demographics, 5-2-1-0 behavioral targets, and anthropometric measures were obtained from 54 enrollees. Pre- and post-program weight, body mass index (BMI) percentile, and 5-2-1-0 behavioral targets were compared for 20 patients who completed the program which consisted of a total of five visits over 3 months. RESULTS: Participants showed a significant reduction in their BMI, improvement in daily servings of fruits and vegetables, reduction in recreational screen time from baseline, improvement in daily physical activity, and reduction in consumption of sugary beverages. CONCLUSIONS: These preliminary findings are a promising indicator that primary care-based obesity interventions may be effective for the management and treatment of pediatric obesity. IMPLICATIONS FOR NURSING: This evidence-based toolkit provides a practical point-of-care guidance on the prevention, assessment, and treatment of childhood obesity and can be easily implemented in other primary care settings.

Hypertension and selected indicators of health assessment in a population of 19-year-old men subject to military qualifications.

Assessment the prevalence of hypertension and its relation to selected indicators of health status and performance, including classification of BMI, obesity classifications, and body structure in a large test group of 19-year-old men.The study was observational-retrospective, and included a group of 17,282 men, aged 19, from the Malopolska region. All subjects met the qualifications for compulsory military service in 2017. We analyzed selected data obtained from the records of the Ministry of National Defense-spiral-ZINT. Data collection and analysis were carried out from April 1, 2018 to August 31, 2018.Hypertension was found at 0.6%, weak body structure at 0.8% and obesityco-existing with cardiorespiratory insufficiency has been reported 2.6% of respondents and it was more frequent in the recruiters from HT II than I. The underweight concerned almost 7%, and the overweight and obesity of 1/4 of conscripts. The vast majority of people with hypertension were characterized by excessive body weight (74.8%), mainly overweight.Hypertension was seen in a negligible percentage of males studied and was significantly associated with an increase in BMI, particularly with regards to being overweight.

Establishing an enduring Military Trauma Mortality Review: Misconceptions and lessons learned.

Under direction from the Defense Health Agency, subject matter experts (SMEs) from the Joint Trauma System, Armed Forces Medical Examiner System, and civilian sector established the Military Trauma Mortality Review process. To establish the most empirically robust process, these SMEs used both qualitative and quantitative methods published in a series of peer-reviewed articles over the last 3 years. Most recently, the Military Mortality Review process was implemented for the first time on all battle-injured service members attached to the United States Special Operations Command from 2001 to 2018. The current Military Mortality Review process builds on the strengths and limitations of important previous work from both the military and civilian sector. To prospectively improve the trauma care system and drive preventable death to the lowest level possible, we present the main misconceptions and lessons learned from our 3-year effort to establish a reliable and sustainable Military Trauma Mortality Review process. These lessons include the following: (1) requirement to use standardized and appropriate lexicon, definitions, and criteria; (2) requirement to use a combination of objective injury scoring systems, forensic information, and thorough SME case review to make injury survivability and death preventability determinations; (3) requirement to use nonmedical information to make reliable death preventability determinations and a comprehensive list of opportunities for improvement to reduce preventable deaths within the trauma care system; and (4) acknowledgment that the military health system still has gaps in current infrastructure that must be addressed to globally and continuously implement the process outlined in the Military Trauma Mortality Review process in the future.

Tactical Combat Casualty Care Training, Knowledge, and Utilization in the US Army.

INTRODUCTION: Tactical Combat Casualty Care (TCCC) is the execution of prehospital trauma skills in the combat environment. TCCC was recognized by the 2018 Department of Defense Instruction on Medical Readiness Training as a critical wartime task. This study examines the training, understanding, and utilization of TCCC principles and guidelines among US Army medical providers and examines provider confidence of medics in performing TCCC skills. MATERIALS AND METHODS: A cross-sectional survey, developed by members of the Committee on TCCC, was distributed to all US Army Physicians and Physician Assistants via anonymous electronic communication. RESULTS: A total of 613 completed surveys were included in the analyses. Logistic regression analyses were conducted on: TCCC test score of 80% or higher, confidence with medic utilization of TCCC, and medic utilization of ketamine in accordance with TCCC. CONCLUSIONS: <60% of respondents expressed confidence in the ability of the medics to perform all TCCC skills. Supervising providers who that believed 80 to 100% of their medics had completed TCCC training had more confidence in their medic's TCCC abilities. With TCCC, a recognized lifesaver on the battlefield, continued training and utilization of TCCC concepts are paramount for deploying personnel.

It Totally Possibly Could Be: How a Group of Military Physicians Reflect on Their Clinical Reasoning in the Presence of Contextual Factors.

INTRODUCTION: Contextual factors (eg, diagnostic suggestion and burnout) can affect physician clinical reasoning performance, leading to diagnostic error. Yet, contextual factors have only recently been studied and none of that work focused on how physicians appraise (ie, evaluate) the clinical situation as they reason. The purpose of this qualitative study was to use appraisal to describe the effect of contextual factors on clinical reasoning. MATERIALS AND METHODS: Physicians (n = 25) either viewed two video cases or participated in two live scenarios, one with contextual factors and one without. Afterwards, they completed a "think-aloud" reflection while reviewing the cases. Transcribed think-alouds were coded for appraisal markers, comparing cases with and without contextual factors. RESULTS: When contextual factors were present, participants expressed more emotional evaluation and uncertainty about those emotions. Across all types of cases, participants expressed uncertainty about the case and assessed what "could" or "would" have gone differently. CONCLUSIONS: This study suggests that one major effect of contextual factors may be that they induce emotions, which may affect the process of clinical reasoning and diagnostic error. It also suggests that uncertainty may be common in clinical practice, and we should thus further explore its impact.

Usefulness of point-of-care ultrasound in military medical emergencies performed by young military medicine residents.

INTRODUCTION: To evaluate the usefulness of point-of-care ultrasound (POCUS) performed by young military medicine residents after short training in the diagnosis of medical emergencies. METHODS: A prospective study was performed in the emergency department of a French army teaching hospital. Two young military medicine residents received ultrasound training focused on gall bladder, kidneys and lower limb veins. After clinical examination, they assigned a 'clinical diagnostic probability' (CP) on a visual analogue scale from 0 (definitely not diagnosis) to 10 (definitive diagnosis). The same student performed ultrasound examination and assigned an 'ultrasound diagnostic probability' (UP) in the same way. The absolute difference between CP and UP was calculated. This result corresponded to the Ultrasound Diagnostic Index (UDI), which was positive if UP was closer to the final diagnosis than CP (POCUS improved the diagnostic accuracy), and negative conversely (POCUS decreased the diagnostic accuracy). RESULTS: Forty-eight patients were included and 48 ultrasound examinations were performed. The present pathologies were found in 14 patients (29%). The mean UDI value was +3 (0-5). UDI was positive in 35 exams (73%), zero in 12 exams (25%) and negative in only one exam (2%). CONCLUSION: POCUS performed after clinical examination increases the diagnostic accuracy of young military medicine residents.

Treatment of military cases of cerebrospinal fever during WWI: the concerted efforts of the RAMC, MRC and Lister Institute to make serum therapy work.

Cerebrospinal fever was rare in the British Army prior to World War I. An outbreak of the disease on Salisbury Plain in late 1914 posed new challenges. The War Office established the Central Cerebrospinal Fever Laboratory at the Royal Army Medical (RAM) College early in 1915 to conduct research, develop diagnostic tests and coordinate the military response. The Royal Army Medical Corps (RAMC) set up dedicated cerebrospinal wards for the hospitalisation and treatment of patients. The new Medical Research Committee (MRC) supported bacteriological studies of epidemic strains of the meningococcus responsible for the outbreak. The Lister Institute of Preventive Medicine, an independent research institution, acted as a key supplier of antimeningococcus serum. The mortality of military patients during 1915 was poor because the testing infrastructure was still developing, the RAMC had limited experience of treating cases, and the therapeutic serums available at the time seemed ineffective. The survival rate of home troops improved during the war-through the concerted efforts of the RAMC, MRC and Lister Institute-due to timely diagnosis, and early, intensive and prolonged treatment with improved serums. The Official History of the War highlights subsequent trials undertaken with strain-specific MRC serums in late 1918 and 1919 but fails to acknowledge that in late 1917/early 1918 the Lister Institute supplied the RAM College with large quantities of an efficacious multivalent serum and corresponding monovalent serums that were not included in a formal trial.

Evolution of military medicine literature: a scientometric study of global publications on military medicine between 1978 and 2017.

OBJECTIVES: Scientometrics is a popular statistical discipline providing data relevant to publication patterns and trends in a certain academic field. There are no scientometric analyses of publications produced in military medicine literature. The present study aims to perform a holistic analysis of military medicine literature. METHODS: All data of this study were collected from the Web of Science Core Collection. All indexed documents between 1978 and 2017 were included. Countries, authors, institutions, citations and keywords relevant to the military medicine literature were comprehensively analysed. An infomap revealing global productivity and infographics of scientometric networks were generated. RESULTS: A total of 48 240 published items were found, 82.29% of which were original articles. USA, covering 56.66% of all literature dominated the military medicine field followed by the UK, China, Canada and Israel. We found that 18 of 20 most productive institutions in the world were from USA and the US Department of Defense was the most contributing institution in the literature with 9664 documents. The most used keywords over a 40-year period were 'military', 'veterans', 'posttraumatic stress disorder' and 'military personnel'. A scientometric network of keywords showed a complicated 'starburst pattern'. CONCLUSION: All most contributing countries except Turkey, China and Israel were developed nations. Only one institution (Tel Aviv University) from developing countries was noted in the list of 20 most productive institutions. The researchers from developing and the least developed countries should be encouraged and supported to carry out novel studies on military medicine.
