Advanced Surgical Skills for Exposure in Trauma (ASSET) course improves military surgeon confidence.

OBJECTIVE: Active duty military surgeons often have limited trauma surgery experience prior to deployment. Consequently, military-civilian training programs have been developed at high-volume trauma centers to evaluate and maintain proficiencies. Advanced Surgical Skills for Exposure in Trauma (ASSET) was incorporated into the predeployment curriculum at the Army Trauma Training Detachment in 2011. This is the first study to assess whether military surgeons demonstrated improved knowledge and increased confidence after taking ASSET. DESIGN: Retrospective cohort study. SETTING: Quaternary care hospital. PATIENTS AND PARTICIPANTS: Attending military surgeons who completed ASSET between July 2011 and October 2020. MAIN OUTCOME MEASURE(S): Pre- and post-course self-reported comfort level with procedures was converted from a five-point Likert scale to a percentage and compared using paired t-tests. RESULTS: In 188 military surgeons, the median time in practice was 3 (1-8) years, with specialties in general surgery (52 percent), orthopedic surgery (29 percent), trauma (7 percent), and other disciplines (12 percent). The completed self-evaluation response rate was 80 percent (n = 151). The self-reported comfort level for all body regions improved following course completion (p < 0.001): chest (27 percent), neck (23 percent), upper extremity (22 percent), lower extremity (21 percent), and abdomen/pelvis (19 percent). The overall score on the competency test improved after completion of ASSET, with averages increasing from 62 ± 18 percent pretest to 71 ± 13 percent post-test (p < 0.001). CONCLUSIONS: After taking the ASSET course, military surgeons demonstrated improved knowledge and increased confidence in the operative skills taught in the course. The ASSET course may provide sustainment of knowledge and confidence if used at regular intervals to maintain trauma skills and deployment readiness.

[The review of the monograph "Ambroise Paré. The first surgeon of the Kingdom" by E. E. Berger].

The review considers the approach placing famous French surgeon A. Paré into more general European context of European Renaissance of XVI century and into local context of intellectual life of Paris of this period. The refutation of widespread in history of medicine opinion about strict separation of university medicine from artisan surgery in Medieval Europe is discussed.

Defining capabilities in deployed UK military prehospital emergency care.

The UK military prehospital emergency care (PHEC) operational clinical capability framework must be updated in order that it retains its use as a valid operational planning tool. Specific requirements include accurately defining the PHEC levels and the 'Medical Emergency Response Team' (MERT), while reinforcing PHEC as a specialist area of clinical practice that requires an assured set of competencies at all levels and mandatory clinical currency for vocational providers.A military PHEC review panel was convened by the Defence Consultant Advisor (DCA) for PHEC. Each PHEC level was reviewed and all issues which had, or could have arisen from the existing framework were discussed until agreement between the six members of this panel was established.An updated military PHEC framework has been produced by DCA PHEC, which defines the minimum requirements for each operational PHEC level. These definitions cover all PHEC providers, irrespective of professional background. The mandatory requirement for appropriate clinical exposure for vocational and specialist providers is emphasised. An updated definition of MERT has been agreed.This update provides clarity to the continually evolving domain of UK military PHEC. It sets out the PHEC provider requirements in order to be considered operationally deployable in a PHEC role. There are implications for training, manning and recruitment to meet these requirements, but the processes required to address these are already underway and well described elsewhere.

Do You See What I See? A Comparison of CCC and Self-Assigned Milestones Across Military Medical Specialties.

BACKGROUND: The Accreditation Council for Graduate Medical Education (ACGME) requires residency programs to complete competency-based assessments of medical trainees based on nationally established Milestones. Previous research demonstrates a strong correlation between CCC and resident scores on the Milestones in surgery, but little is known if this is true between specialties. In this study, we investigated a variety of specialties and sought to determine what factors affect self-assessment of milestones. In addition, a post-hoc analysis was completed on the COVID-19 pandemic effects on self-evaluation. METHODS: This is an IRB approved observational study on prospectively collected self-evaluation milestone data that is used within each ACGME program's Clinical Competency Committees. Medical trainees within the San Antonio Uniformed Services Health Education Consortium were approached for possible participation in this study with permission from program directors. RESULTS: There was no significant difference between self-assessments and CCC-assessments based on self-identified gender or residency type (surgical versus nonsurgical) for any milestone domain. Within the postgraduate year (PGY) groups, the PGY5 and PGY6 tended to rate themselves higher than CCC. Chiefs (Internal Medicine PGY2/3, and General Surgery PGY5/6) tended to be more accurate in scoring themselves than the interns (PGY1) within the milestone of Interpersonal Skills and Communication (chiefs 0.5 vs. interns 0.62, p = 0.03). On post hoc analysis of self-rating, during the first wave of the COVID 19 pandemic, Post-Covid residents were more likely to underrate themselves in Systems-Based Practice compared to the Pre-Covid cohort (-0.49 vs 0.10; p = 0.007) and more likely to rate themselves higher in Professionalism (-0.54 vs. -0.10, p = 0.012). CONCLUSION: Unique to this study and our institution, there was no gender difference found in self vs CCC evaluations. With the change in learning environment from COVID, there was also a change in ability for some learners to self-assess accurately. As medical educators, we should understand the importance of both encouraging learners to practice self-assessment as well as give feedback to trainees on their progress. We also need to educate our faculty on the use of milestones for assessment to create a true gold standard in the CCC.

The first two years of the use of low titer group O whole blood during French Military overseas operations: A retrospective study.

BACKGROUND: On the battlefield, hemorrhage is the main cause of potentially preventable death. To reduce mortality due to hemorrhagic injuries, the French Military Medical Service (FMMS) has deployed low titer group O whole blood (LTOWB) since June 2021 during operation BARKHANE in the Sahel-Saharan strip. Questions persist regarding the circumstances under which the FMMS employs LTOWB during overseas operations. STUDY DESIGN: We performed a retrospective analysis of all LTOWB transfused by the FMMS during overseas operations in the Sahel-Saharan strip between June 1, 2021, and June 1, 2023. Information was collected from battlefield forward transfusion sheets. RESULTS: Over the 2-year study period, 40 units of LTOWB were transfused into 25 patients. Of the 25 patients, 18 were combat casualties and seven were transfused for non-trauma surgery. Of the 40 units of LTOWB transfused, 22 were provided during Role 2 care, 11 during tactical medical evacuation (MEDEVAC), and seven in light and mobile surgical units. Among combat casualties, LTOWB was the first blood product transfused in 13 patients. In combat casualties, 6 h post-trauma, the median ratio of plasma: red blood cells (RBCs) was 1.5, and the median equivalent platelet concentrate (PC) transfused was 0.17. No immediate adverse events related to LTOWB transfusion were reported. CONCLUSION: LTOWB is transfused by the FMMS during overseas operations from the tactical MEDEVAC until Role 2 care. Deployment of LTOWB by the FMMS enables an early high-ratio plasma/RBC transfusion and an early platelet transfusion for combat casualties.

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.

European military surgical teams in combat theater: A survey study on deployment preparation and experience.

INTRODUCTION: Adequate (predeployment) training of the nowadays highly specialized Western military surgical teams is vital to ensure a broad range of surgical skills to treat combat casualties. This survey study aimed to assess the self-perceived preparedness, training needs, deployment experience, and post-deployment impact of surgical teams deployed with the Danish, Dutch, or Finnish Armed Forces. Study findings may facilitate a customized predeployment training. METHODS: A questionnaire was distributed among Danish, Dutch, and Finnish military surgical teams deployed between January 2013 and December 2020 (N = 142). The primary endpoint of self-perceived preparedness ratings, and data on the training needs, deployment experiences, and post-deployment impacts were compared between professions and nations. RESULTS: The respondents comprised 35 surgeons, 25 anesthesiologists, and 39 supporting staff members, with a response rate of 69.7 % (99/142). Self-perceived deployment preparedness was rated with a median of 4.0 (IQR 4.0-4.0; scale: 1 [very unprepared]-5 [more than sufficient]). No differences were found among professions and nations. Skills that surgeons rated below average (median <6.0; scale: 1 [low]-10 [high]) included tropical disease management and maxillofacial, neurological, gynecological, ophthalmic, and nerve repair surgery. The deployment caseload was most often reported as <1 case per week (41/99, 41.4 %). The need for professional psychological help was rated at a median of 1.0 (IQR 1.0-1.0; scale: 1 [not at all]-5 [very much]). CONCLUSIONS: Military surgical teams report overall adequate preparedness for deployment. Challenges remain for establishing broadly skilled teams because of a low deployment caseload and ongoing primary specializations. Additional training and exposure were indicated for several specialism-specific skill areas. The need for specific training should be addressed through customized predeployment programs.

Piloting delivery of PfSPZ vaccines for malaria through a cryogenic vaccine cold chain to travel and military medicine clinics.

BACKGROUND: PfSPZ vaccines comprising Plasmodium falciparum (Pf) sporozoites (SPZ) have demonstrated > 90% protection against variant Pf malaria infections for at least 12 weeks; they are the only vaccines with the level of efficacy necessary to protect travellers. PfSPZ are eukaryotic cells stabilized by cryopreservation and distributed using a cryogenic (below -150 °C) cold chain. The Ebola vaccine and mRNA vaccines against SARS-CoV-2 pioneered uptake of vaccines requiring non-standard ultra-low temperature cold chains. The cryogenic cold chain using liquid nitrogen (LN2) vapour phase (LNVP) cryoshippers, is simpler, more efficient than -80, -20 or 2-8 °C cold chains, and does not use electricity. This study was conducted to evaluate implementation and integration of a cryogenically distributed vaccine at travel and military immunization clinics. METHODS: We conducted sequential 28-day studies evaluating vaccine shipping, storage, maintenance and accession at two US military and two civilian travel health/immunization clinics. In each clinic, personnel were trained in equipment use, procurement and handling of LN2, temperature monitoring and inventory record keeping by in-person or video instruction. RESULTS: Sites required 2-4 h/person for two persons to assimilate and develop the expertise to manage vaccine storage and LNVP operations. LN2 for recharging cryoshippers was delivered every 1-2 weeks. Vaccine ordering, receipt, storage and inventory control was conducted effectively. Simulated single dose vaccine cryovial retrieval and thawing were performed successfully in different travel clinic settings. Continuous temperature monitoring at each site was maintained with only one short excursion above -150 °C (-145 °C) through shipping, use and reverse logistics. Staff, during and at study conclusion, provided feedback that has been incorporated into our models for cold chain logistics. CONCLUSIONS: These studies demonstrated that the training in delivery, storage, administration and integration of PfSPZ vaccines can be successfully managed in different immunization clinic settings for travellers and military personnel.

Next-generation tourniquet: Recommendations for future capabilities and design requirements.

BACKGROUND: Advances in tourniquet development must meet new military needs for future large-scale combat operations or civilian mass casualty scenarios. This includes the potential use of engineering and automation technologies to provide advanced tourniquet features. A comprehensive set of design capabilities and requirements for an intelligent or smart tourniquet needed to meet the challenges currently does not exist. The goal of this project was to identify key features and capabilities that should be considered for the development of next-generation tourniquets. METHODS: We used a modified Delphi consensus technique to survey a panel of 34 tourniquet subject matter experts to rate various statements and potential design characteristics relevant to tourniquets systems and their use scenarios. Three iterative rounds of surveys were held, followed by virtual working group meetings, to determine importance or agreement with any given statement. We used a tiered consensus system to determine final agreement over key features that were viewed as important or unimportant features or capabilities. This information was used to refine and clarify the necessary tourniquet design features and adjust questions for the following surveys. RESULTS: Key features and capabilities of various were agreed upon by the panelists when consensus was reached. Some tourniquet features that were agreed upon included but are not limited to: Capable of being used longer than 2 hours, applied and monitored by anyone, data displays, semiautomated capabilities with inherent overrides, automated monitoring with notifications and alerts, and provide recommended actions. CONCLUSION: We were able to identify key tourniquet features that will be important for future device development. These consensus results can guide future inventors, researchers, and manufacturers to develop a portfolio of next-generation tourniquets for enhancing the capabilities of a prehospital medical provider. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level V.
