The French Advanced Course for Deployment Surgery (ACDS) calledCours Avancé de Chirurgie en Mission Extérieure (CACHIRMEX): history of its development and future prospects

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.

Emergency Cranial Surgeries Without the Support of a Neurosurgeon: Experience of the French Military Surgeons

INTRODUCTION

Unlike orthopedic or visceral surgeons, French military neurosurgeons are not permanently deployed on the conflict zone. Thus, craniocerebral war casualties are often managed by general surgeons in the mobile field surgical team. The objective of the study was to provide the feedback of French military surgeons who operated on craniocerebral injuries during their deployment in a role 2 surgical hospital without a neurosurgeon.

MATERIALS AND METHODS

A cross-sectional survey was conducted by phone in March 2020, involving every military surgeon currently working in the French Military Training Hospitals, with an experience of cranial surgery without the support of a neurosurgeon during deployment. We strived to obtain contextual, clinical, radiological, and surgical data.

RESULTS

A total of 33 cranial procedures involving 64 surgeons were reported from 1993 to 2018. A preoperative CT scan was not available in 18 patients (55%). Half of the procedures consisted in debridement of craniocerebral wounds (52%, n = 17), followed by decompressive craniectomies (30%, n = 10), craniotomy with hematoma evacuation (15%, n = 5), and finally one (3%) surgery with exploratory burr holes were performed. The 30-day survival rate was 52% (n = 17) and 50% (n = 10/20) among the patients who sustained severe traumatic brain injury.

CONCLUSIONS

This survey demonstrates the feasibility and the plus-value of a neurosurgical damage control procedure performed on the field by a surgeon nonspecialized in cranial surgery. The stereotyped neurosurgical techniques used by the in-theater surgeon were learned during a specific predeployment training course. However, the use of a live telemedicine neurosurgical support seems indispensable and could benefit the general surgeon in strained resources setting.

Ethical Issues Regarding Neurosurgical Management of Penetrating Brain Injury in the French Armed Forces

Combat penetrating brain injury (PBI) differs significantly from PBI in civilian environments. Differences include technical factors such as the weapons involved, strained resource environments, and limited medical materials and human resources available. Ethical issues regarding the management of PBI in military settings may occur. This case study examines the case of a 20-year-old member of the French Armed Forces that suffered a penetrating brain injury in a combat situation. The four-quadrant method along with the four principles of medical ethics (respect for autonomy, beneficence, nonmaleficence, and justice) was used to analyze this case and to apply ethics to the practice of military medicine. Nowadays, we possess the medical and surgical resources as well as the aeromedical evacuation capability to save the life of a soldier with a penetrating craniocerebral wound. Nonetheless, the functional outcome of this type of wound places military doctors in an ethical dilemma. The line of conduct and clinical protocol established by the French Medical Health Service is to manage all PBIs when the patient's life can be saved and to provide all available financial and social support for the rehabilitation of patients and their family.

Concordance of CT imaging and surgical lesions in penetrating abdominal trauma

OBJECTIVE

The management of penetrating abdominal wounds has greatly benefited from the development of computed tomography (CT), particularly in stable patients. In this setting, the scanner is the reference examination. Our study aims to evaluate the performance of preoperative CT in the assessment of penetrating abdominal lesions.

MATERIAL AND METHODS

Between January 1, 2015 and January 1, 2022, 81 patients were hospitalized following penetrating abdominal trauma at the Army Training Hospitals of Sainte-Anne and Laveran. Fifty-one stable patients who had an abdominopelvic CT scan and thereafter underwent abdominal surgery (laparotomy or laparoscopy) were included. Radiological and surgical data were collected from the electronic record and compared by a descriptive analysis (calculation of the sensitivity, specificity, positive and negative predictive value of the CT for the detection of lesions of the various organs) and by a correlation of the CT findings with surgical findings using Kripendorff's alpha coefficient.

RESULTS

The cohort was largely male (n=45; 88%), with injuries by knife wound in 62.7% of cases (n=32) and gunshot in 35.3% (n=18) of cases. The median age was 36years (25-47). The median index of severity score (ISS) was 17 (10-26). Excellent agreement between predicted and actual findings was obtained for solid organs (α=0.801) with high sensitivity and specificity (81.8% and 96.6%, respectively). The largest discrepancies were observed for the hollow organs (α=26.2%, sensitivity of 53.3% and specificity of 76.2%) and the diaphragm (α=67.3%, sensitivity 75%, specificity 92.3%). Surgical exploration was non-therapeutic for five patients (9.8%). The failure rate for non-operative treatment was 10% (n=1).

CONCLUSION

CT detection of solid organ lesions in patients with penetrating abdominal wounds is excellent. However, the detection of hollow organ and diaphragmatic wounds remains a challenge with a risk of over- and underdiagnosis. Laparoscopic exploration should be able to fill in the gaps in the CT findings.

Nine years of surgical activity in the deployed French military role 2 medical treatment facility in Mali

INTRODUCTION

In January 2013, France launched a military operation in Mali, which ended in August 2022. This study aimed to analyse the global activity performed by a surgical team within the role 2 medical treatment facility (MTF) deployed in Gao during this period, in order to adapt medical battlefield support and combat casualty care teaching.

METHODS

A retrospective study was conducted using the French surgical database OpEX (French Military Health Service) from January 2013 to August 2022. All patients operated on were included.

RESULTS

During this period, 1298 patients with a median age of 29 (range: 23-38) years were included. Among them, 229 (17.6%) underwent a combat-related trauma surgery (CRTS), 234 (18.0%) underwent a non-CRTS, 167 (12.9%) underwent a non-trauma-related surgery and 668 (51.5%) underwent a scheduled surgery in the context of medical supply to the population.Among the CRTS group, 195 (85.2%) patients underwent an orthopaedic procedure, 73 (31.8%) required a general surgery. Finally, 15 (6.6%) wounded required a specialised surgery.

CONCLUSIONS

In line with the activity described in the role 2 MTF deployed in other contemporary asymmetric conflicts, this activity is moderate, especially if only combat-related injuries are considered; medical support to the population occupied most of the surgical activity. For CRTS, most of the traumas are limb traumas. Other traumas are composed of various lesions, which are often life-threatening. This fact imposes the presence of an orthopaedic surgeon with the appropriate equipment, as well as a general surgeon with a wide range of skills, in asymmetric conflicts.

Early Evaluation of a New French Surgery Course in the Best Practice of Dealing With Major Incidents and Mass Casualty Events

OBJECTIVE

The main objective of this study is to evaluate the impact of a nationwide 5-month course aimed to prepare surgeons for Major Incidents through the acquisition of key knowledge and competencies. Learners' satisfaction was also measured as a secondary objective.

DESIGN

This course was evaluated thanks to various teaching efficacy metrics, mainly based on Kirkpatrick's hierarchy in medical education. Gain in knowledge of participants was evaluated by multiple-choice tests. Self-reported confidence was measured with 2 detailed pre and post training questionnaires.

SETTING

Creation in 2020 of a nationwide, optional and comprehensive Surgical Training in War and Disaster Situation as part of the French surgery residency program. In 2021, data was gathered regarding the impact of the course on participants' knowledge and competencies.

PARTICIPANTS

The study included 26 students in the 2021 cohort (13 residents and 13 practitioners).

RESULTS

Mean scores were significantly higher in the post-test compared to the pre-test, showing significant increase in participants' knowledge during the course: 73,3% vs. 47,3% respectively (p ≤ 0.001). Average learners' confidence scores to perform technical procedures showed at least a +1-point increase on the Likert scale for 65% of items tested (p ≤ 0.001). 89% of items showed at least a +1-point increase on the Likert scale when it came to average learners' confidence score on dealing with complicated situations (p ≤ 0.001). Our post-training satisfaction survey showed that 92% of all participants have noticed the impact of the course on their daily practice.

CONCLUSION

Our study shows that the third level of Kirkpatrick's hierarchy in medical education was reached. This course therefore appears to be meeting the objectives set by the Ministry of Health. Being only 2 years old, it is on the road to gathering momentum and further development.

Head Face and Neck Surgeon Deployment in the New French Role 2: The Damage Control Resuscitation and Surgical Team

INTRODUCTION

High-intensity conflict is back after decades of asymmetric warfare. With the increase in the incidence of head, face, and neck (HFN) injuries, the French Medical Military Service has decided to deploy HFN surgeons in the new French Role 2: the Damage Control, Resuscitation, and Surgical Team (DCRST). This study aims to provide an overview of HFN French surgeons from their initial training, including the surgical skills required, to their deployment on the DCRST.

MATERIALS AND METHODS

The DCRST is a tactical mobile medico-surgical structure with several configurations depending on the battlefield, mission, and flux of casualties. It represents the new French paradigm for the management of combat casualties, including HFN injuries.

RESULTS

The HFN's military surgeon training starts during residency with rotation in the different subspecialties. The HFN surgeon follows a training course called "The French Course for Deployment Surgery" that provides sufficient background to manage polytrauma, including HFN facilities on modern warfare. We have reviewed the main surgical procedures required for an HFN military surgeon.

CONCLUSION

The systematic deployment of HFN surgeons in Role 2 is a specificity of the French army as well as the HFN surgeon's training.Currently, the feedback from an asymmetric conflict is encouraging. However, it will have to innovate to adapt to modern warfare.

Plastic and Maxillofacial Training for War-Zones - A Systematic Review

Study Design

Injuries sustained in war-zones are variable and constantly developing according to the nature of the ongoing conflict. Soft tissue involvement of the extremities, head and neck often necessitates reconstructive expertise. However, current training to manage injuries in such settings is heterogenous. This study involves a systematic review.

Objective

To evaluate interventions in place to train Plastic and Maxillofacial surgeons for war-zone environments so that limitations to current training can be addressed.

Methods

A literature search of Medline and EMBase was performed using terms relevant to Plastic and Maxillofacial surgery training and war-zone environments. Articles that met the inclusion criteria were scored then educational interventions described in included literature were categorised according to their length, delivery style and training environment. Between-group ANOVA was performed to compare training strategies.

Results

2055 citations were identified through this literature search. Thirty-three studies were included in this analysis. The highest scoring interventions were over an extended time-frame with an action-oriented training approach, using simulation or actual patients. Core competencies addressed by these strategies included technical and non-technical skills necessary when working in war-zone type settings.

Conclusions

Surgical rotations in trauma centers and areas of civil strife, together with didactic courses are valuable strategies to train surgeons for war-zones. These opportunities must be readily available globally and be targeted to the surgical needs of the local population, anticipating the types of combat injuries that often occur in these environments.

Operative Trauma Courses: A Scoping Review to Inform the Development of a Trauma Surgery Course for Low-Resource Settings

BACKGROUND

A multitude of operative trauma courses exist, most of which are designed for and conducted in high-resource settings. There are numerous barriers to adapting such courses to low- and low-middle-income countries (LMICs), including resource constraints and contextual variations in trauma care. Approaches to implementing operative trauma courses in LMICs have not been evaluated in a structured manner.

METHODS

We conducted a scoping review of the literature including databases (e.g., PubMed, Web of Science, EMBASE), grey literature repositories, and structured queries of publicly available course materials to identify records that described operative trauma courses offered since 2000.

RESULTS

The search identified 3,518 non-duplicative records, of which 48 relevant reports were included in analysis. These reports represented 23 named and 11 unnamed operative trauma courses offered in 12 countries. Variability existed in course format and resource requirements, ranging from USD 40 to 3,000 per participant. Courses incorporated didactic and laboratory components, which utilized simulations, cadavers, or live animals. Course content overlapped significantly but was not standardized. Data were lacking on course implementation and promulgation, credentialing of instructors, and standardized evaluation metrics.

CONCLUSIONS

While many operative trauma courses have been described, most are not directly relatable to LMICs. Barriers include cost-prohibitive fees, lack of resources, limited data collection, and contextual variability that renders certain surgical care inappropriate in LMICs. Gaps exist in standardization of course content as well as transparency of credentialing and course implementation strategies. These issues can be addressed through developing an open-access operative trauma course for low-resource settings.

Learning trauma surgery through cytoreductive surgery

OBJECTIVES

Regarding war surgery (WS), the initial and continuing education of French military gastrointestinal surgeons (FMGIS) is considered flawed and inappropriate. This results from the low incidence of gastrointestinal (GI) trauma, its predominantly non-surgical management, and a daily surgical practice that strongly differs from WS. Conversely, cytoreductive surgery (CRS) of peritoneal metastases has similarities with WS which led us to assess its potential contribution to the initial and continuing education of FMGIS in WS.

METHODS

We reported the activities of the GI surgery departments of the military teaching hospitals of Percy and Begin. The first one dedicated to traumatology and the second to CRS. We then specifically looked into the surgical procedures conducted by the FMGIS during deployment from January 2004 to December 2014.

RESULTS

Amongst the 600 severe trauma patients admitted to the Percy trauma center between January 2019 and December 2020, 17 underwent abdominal surgery with a total of 25 procedures performed. During the same period, 61 patients undertook CRS in Begin with an average of 7 surgical processes per patient carried out and a total of 418 abdominal surgical procedures. Outside abdominal packing and nephrectomy (not performed in CRS), the numbers of splenectomy, gastrointestinal / gynecological resections (hysterectomy and/or adnexectomy), or liver resection were higher during CRS compared to abdominal trauma surgery with 10 times less patients (10 vs 1, 43 vs 9, 20 vs 0, 6 vs 0, respectively).

CONCLUSION

CRS, through its similarities with WS, seemed to be an appropriate tool for the initial and continuing education of FMGIS in WS and, to an extent, of civilian trauma surgeons who could eventually treat terrorist attacks casualties on the national territory.

Animal model-based simulation training for three emergent and urgent operations of penetrating thoracic injuries

PURPOSE

To develop animal models of penetrating thoracic injuries and to observe the effects of the animal model-based training on improving the trainees' performance for emergent and urgent thoracic surgeries.

METHODS

With a homemade machine, animal models of lung injuries and penetrating heart injuries were produced in porcine and used for training of chest tube drainage, urgent sternotomy, and emergent thoracotomy. Coefficient of variation of abbreviated injury scale and blood loss was calculated to judge the reproducibility of animal models. Five operation teams from basic-level hospitals (group A) and five operation teams from level III hospitals (group B) were included to be trained and tested. Testing standards for the operations were established after thorough literature review, and expert questionnaires were employed to evaluate the scientificity and feasibility of the testing standards. Tests were carried out after the training. Pre- and post-training performances were compared. Post-training survey using 7-point Likert scale was taken to evaluate the feelings of the trainees to these training approaches.

RESULTS

Animal models of the three kinds of penetrating chest injuries were successfully established and the coefficient of variation of abbreviated injury scale and blood loss were all less than 25%. After literature review, testing standards were established, and expert questionnaire results showed that the scientific score was 7.30 ± 1.49, and the feasibility score was 7.50 ± 0.89. Post-training performance was significantly higher in both group A and group B than pre-training performance. Post-training survey showed that all the trainees felt confident in applying the operations and were generally agreed that the training procedure were very helpful in improving operation skills for thoracic penetrating injury.

CONCLUSIONS

Animal model-based simulation training established in the current study could improve the trainees' performance for emergent and urgent thoracic surgeries, especially of the surgical teams from basic-level hospitals.

Emergency department thoracotomy in a physician-staffed trauma system: the experience of a French Military level-1 trauma center

PURPOSE

To investigate survival after emergency department thoracotomy (EDT) in a physician-staffed emergency medicine system.

METHODS

This single-center retrospective study included all in extremis trauma patients who underwent EDT between 2013 and 2021 in a military level 1 trauma center. CPR time exceeding 15 minutes for penetrating trauma of 10 minutes for blunt trauma, and identified head injury were the exclusion criteria.

RESULTS

Thirty patients (73% male, 22/30) with a median age of 42 y/o [27-64], who presented mostly with polytrauma (60%, 18/30), blunt trauma (60%, 18/30), and severe chest trauma with a median AIS of 4 3-5 underwent EDT. Mean prehospital time was 58 min (4-73). On admission, the mean ISS was 41 29-50, and 53% (16/30) of patients had lost all signs of life (SOL) before EDT. On initial work-up, Hb was 9.6 g/dL [7.0-11.1], INR was 2.5 [1.7-3.2], pH was 7.0 [6.8-7.1], and lactate level was 11.1 [7.0-13.1] mmol/L. Survival rates at 24 h and 90 days after penetrating versus blunt trauma were 58 and 41% versus 16 and 6%, respectively. If SOL were present initially, these values were 100 and 80% versus 22 and 11%.

CONCLUSION

Among in extremis patients supported in a physician-staffed emergency medicine system, implementation of a trauma protocol with EDT resulted in overall survival rates of 33% at 24 h and 20% at 90 days. Best survival was observed for penetrating trauma or in the presence of SOL on admission.

Military Orthopedic Surgeons Are Not Just Traumatologists

INTRODUCTION

Each French military orthopedic surgeon is both an orthopedic surgeon and a trauma surgeon. Their mission is to support the armed forces in France and on deployment. The aim of this study was to describe the type of orthopedic surgery performed for the armed forces in France. Our hypothesis was that scheduled surgery was more common than trauma surgery.

METHODS

We conducted a retrospective descriptive analysis of the surgical activity for military patients in the orthopedic surgery departments of the four French military platform hospitals. All surgical procedures performed during 2020 were collected. We divided the procedures into the following categories: heavy and light trauma, posttraumatic reconstruction surgery, sports surgery, degenerative surgery, and specialized surgery. Our primary endpoint was the number of procedures performed per category.

RESULTS

A total of 827 individuals underwent surgery, 91 of whom (11%) were medical returnees from deployment. The surgeries performed for the remaining 736 soldiers present in metropolitan France (89%) consisted of 181 (24.6%) trauma procedures (of which 86.7% were light trauma) and 555 (75.4%) scheduled surgery procedures (of which 60.8% were sports surgery). Among the medical returnees, there were 71 traumatology procedures (78%, of which 87.3% were light traumatology) and 20 procedures corresponding to surgery usually carried out on a scheduled basis (22%, of which 95% were sports surgery).

CONCLUSION

Military orthopedic surgeons are not just traumatologists; their activity for the armed forces is varied and mainly consists of so-called programmed interventions.

The French Pre-Deployment Advanced Course in Anesthesia and Resuscitation: Development and Future Prospects

INTRODUCTION

Military anesthesiologists from the French Military Medical Service (FMMS) are part of the Forward Surgical Teams deployed in overseas military operations. The practice of anesthesia in combat zones requires specific skills that are not taught during the initial curriculum for French civilian anesthesiologist. The Pre-Deployment Advanced Course in Anesthesia and Resuscitation (DACAR) program was developed to prepare military anesthesiologist from the FMMS before their deployment in overseas military operations.

METHODS

Created in 2013 by the French Military Medical Academy, the DACAR program is divided into two modules and carried out once a year. The DACAR program trains all military anesthesiologist residents at the end of their curricula. Since 2019, a number of Certified Registered Nurse Anesthetists have completed the DACAR program. The DACAR program is organized around the main axes of experience feedback from previous deployments in combat zones as well as didactic learning and practical training using high-fidelity simulation.

RESULTS

Since 2013, a total of 99 trainees completed the DACAR program during six complete cycles of two modules. The DACAR program has gradually been enriched from 14 courses in 2013 to 28 in 2019. Participants' reported satisfaction rates have increased steadily since 2016, when 88% of courses were rated as "interesting" or "very interesting," and only 4% as "not very interesting." By 2019, those figures had improved to 96% and 2%, respectively.

CONCLUSION

The DACAR program is a structured and adapted military medical course aimed at completing the curriculum of military anesthesiologists from the FMMS before deployment in overseas military operations. Regular audits and updates ensure that the DACAR training program maintains the highest standards of quality and rigor.

Role of Cancer Surgery in the Improvement of the Operative Skills of Military Surgeons During Deployment: A Single-Center Study

INTRODUCTION

The maintenance of military surgeons' operative skills is challenging. Different and specific training strategies have been implemented in this context; however, little has been evaluated with regard to their effectiveness. Cancer surgery is a part of military surgeons' activities in their home hospitals. This study aimed to assess the role of oncological surgery in the improvement of military surgeons' operative skills.

METHODS

Between January and June 2019, the surgical activities of the departments of visceral, ear, nose, and throat, urological, and thoracic surgery were retrospectively reviewed and assessed in terms of the operative time (OT). All surgeons working at the Sainte Anne Military Teaching Hospital were sent a survey to rate on a 5-point scale the current surgical practices on their usefulness in improving surgical skills required for treating war injuries during deployment (primary endpoint) and to compare on a 10-point visual analog scale the influence of cancer surgery and specific training on surgical fluency (secondary endpoint).

RESULTS

Over the study period, 2,571 hours of OT was analyzed. Oncological surgery represented 52.5% of the surgical activity and almost 1,350 hours of cumulative OT. Considering the primary endpoint, the mean rating allocated to cancer surgery was 4.53 ± 0.84, which was not statistically different than that allocated to trauma surgery (4.42 ± 1.02, P = 0.98) but higher than other surgery (2.47 ± 1.00, P < 0.001). Considering the secondary endpoint, cancer surgery was rated higher than specific training by all surgeons, without statistically significant difference (positive mean score of + 2.00; 95% IC: 0.85-3.14).

CONCLUSION

This study demonstrates the usefulness of cancer surgery in improving the operative skills of military surgeons.

Evaluation of neurosurgical training of French military surgeons prior to their deployment

BACKGROUND

A specific training course was formalized in 2007 in order to facilitate the management of cranio-encephalic injuries by French military general surgeons during deployment, within the Advanced Course for Deployment Surgery (ACDS). The objective is to evaluate the neurosurgical pre-deployment training course attended by the military surgeons.

METHODS

From June 2019 to September 2019, we conducted a cross-sectional survey in the form of a digital self-completed questionnaire, addressed to all graduated military surgeons working in the French Military Training Hospitals. The survey included: (1) a knowledge assessment; and (2) a self-assessment of the training course. The participating surgeons were classified into two groups according to their participation (group 1) or not (group 2) in the neurosurgical module. The main outcome was the score received on the knowledge assessment.

RESULTS

Among the 145 military surgeons currently in service, 76 participated in our study (53%), of which 49 were classified in group 1 (64%) and 27 in group 2 (36%). Group 1 surgeons had a significantly higher score than Group 2 at the knowledge assessment (mean 21.0±7.1 vs. 17.8±6.0, P=0.041). The most successful questions were related to TBI diagnosis and surgical technique, while the least successful questions dealt with "beyond emergency care" and surgical indications.

CONCLUSION

The French pre-deployment neurosurgical training course provides a strong neurosurgical background, sufficient to perform life-saving procedures in a modern conflict situation. However, neurosurgical specialized advice should be solicited whenever possible to assist the in-theatre surgeon in surgical decisions.

Traum'cast: an online, open-access educational video podcast series for teaching military trauma care to all healthcare providers

The aim of this paper was to describe the development of ‘Traum’cast’, an ambitious project to create a high-quality, open-access, 12-week video podcast programme providing evidence-based continuing medical education for civilian and military healthcare practitioners dedicated to the management of trauma caused by weapons of war. The management of such patients became a particular public health issue in France following the 2015 terrorist attacks in Paris, which highlighted the need for all healthcare professionals to have appropriate knowledge and training in such situations. In 2016, the French Health General Direction asked the French Military Medical Service (FMMS) to create a task force and to use its unique and considerable experience to produce high-quality educational material on key themes including war injuries, combat casualty care, triage, damage control surgery, transfusion strategies, psychological injury and rehabilitation. The material was produced by FMMS and first broadcast in French and for free, on the official FMMS YouTube channel in September 2020. Traum’cast provides evidence-based continuing medical education for civilian and military healthcare practitioners. Traum’cast is an educational innovation that meets a public health requirement.

French civilian surgical expertise still inadequately prepared for mass casualties 3 years after major terror attacks in Paris (2015) and Nice (2016)

BACKGROUND

Three years after the terror attacks in Paris and Nice, this study aims to determine the level of interest, the technical skills and level of surgical activity in exsanguinating trauma care for a nonselected population of practicing French surgeons.

METHODS

A questionnaire was sent between July and December 2017 to French students and practicing surgeons, using the French Surgical Colleges' mailing lists. Items analyzed included education, training, interest and clinical activity in trauma care and damage-control surgery (DCS).

RESULTS

622 questionnaires were analyzed and was composed of 318 (51%) certificated surgeons, of whom 56% worked in university teaching hospitals and 47% in Level I trauma centers (TC1); 44% were digestive surgeons and 7% were military surgeons. The mean score of 'interest in trauma care' was 8/10. Factors associated with a higher score were being a resident doctor (p = 0.01), a digestive surgeon (p = 0.0013), in the military (p = 1,71 × 10) and working in TC1 (p = 0.034). The mean "DCS techniques knowledge" score was 6.2/10 and factors significantly associated with a higher score were being a digestive surgeon (respectively, p = 0.0007 and p = 0.001) and in the military (respectively p = 1.74 × 10 and p = 3.94 × 10). Reported clinical activity in trauma and DCS were low. Additional continuing surgical education courses in trauma were completed by 23% of surgeons.

CONCLUSION

French surgeons surveyed showed considerable interest in trauma care and treatment. Despite this, and regardless of surgical speciality, their theoretical and practical knowledge of necessary DCS skills remain inadequate.

How do deployed general surgeons acquire relevant skill sets and competencies and mitigate skill fade?

There are recognised difficulties internationally with acquisition and retention of skills among deployed military general surgeons. These are compounded by reduced trauma workload in non-deployed roles or during low tempo or limited activity deployments, and the winding-down of combat operations in Iraq and Afghanistan. We summarise the relevant military-run courses, military-civilian collaborations and potential future strategies that have been used to address skill sets and competencies of deployed surgeons. We use examples from the American, British, Danish, French, German and Swedish Armed Forces. There is variation between nations in training, with a combination of didactic lectures, simulation training and trauma placements in civilian settings at home and overseas. Data regarding effectiveness of these techniques are sparse. It is likely that combat surgical skill-set acquisition and maintenance requires a combination of employment at a high-volume trauma centre during a surgeon's non-deployed role, together with military-specific courses and high-fidelity simulation to fill skill gaps. There are multiple newer modalities of training that require further evaluation if they are to prove effective in the future. We aimed to summarise the current methods used internationally to ensure acquisition and retention of vital skill sets for these surgeons.

The Damage Control Resuscitation and Surgical Team: The New French Paradigm for Management of Combat Casualties

INTRODUCTION

The aim of this work was to introduce the new French forward resuscitation and surgical unit. It's also to discuss the choices and waivers granted to fit the tactical context of modern conflicts and the current epidemiology of combat casualties.

MATERIALS AND METHODS

A multidisciplinary task force of 11 people proceeded to the conception and the creation of a new military resuscitation and surgical unit. The preliminary work included a scoping review of the combat casualties' epidemiology in modern conflicts and an analysis of the recent French medical-surgical treatment facilities lessons learned. In April 2019, a technical-operational evaluation was conducted to confirm all the technical, ergonomic, and organizational choices made during the design phase.

RESULTS

The multidisciplinary task force resulted in the creation of the Damage Control Resuscitation and Surgical Team (DCRST). The DCRST focused on the resuscitation strategy, including transfusion of blood products, and the life-saving surgical procedures to be performed as close as possible to the point of injury. It was designed for the resuscitation of two patients: the life-saving surgery of two patients and the very short-term intensive care (<12 hours) of four patients at the same time. The DCRST provided sufficient autonomy to provide take care of four T1 and four T2 or T3 casualties per day for 48 hours. It was armed with 23 soldiers. The technical equipment represented 5,300 kg and 27 m3. All the technical medical equipment could be stored in two 20-foot containers.

CONCLUSION

The DCRST represents a new paradigm in medical support of French military operations. It offers the advantage of two combat casualties' surgical management at the same time, as close as possible to the combat zone. It responds to a 2-fold epidemiological and logistical challenge.

Adding the Capacity for an Intensive Care Unit Dedicated to COVID 19, Preserving the Operational Capability of a French Golden Hour Offset Surgical Team in Sahel

Introduction

In April 2020, the military medical planning needs to be recalibrated to support the COVID-19 crisis during a large-scale combat operation carried out by the French army in Sahel.

Material and Methods

Since 2019, proper positioning of Forward Surgical Teams (FSTs) has been imperative in peer-to-near-peer conflict and led to the development of a far-forward surgical asset: The Golden Hour Offset Surgical Team (GHOST). Dedicated to damage control surgery close to combat, GHOST made the FST aero-mobile again, with a light logistical footprint and a fast setting. On 19 and 25 March 2020, Niger and Mali confirmed their first COVID-19 cases, respectively. The pandemic was ongoing in Sahel, where 5,100 French soldiers were deployed in the Barkhane Operation.

Results

For the first time, the FST had to provide, continuously, both COVID critical care and surgical support to the ongoing operation in Liptako. Its deployment on a Main Operating Base had to be rethought on Niamey, to face the COVID crisis and support ongoing operations. This far-forward surgical asset, embedded with a doctrinal Role-1, sat up a 4-bed COVID intensive care unit while maintaining a casualty surgical care capacity. A COVID training package has been developed to prepare the FST for this innovative employment. This far-forward surgical asset was designed to support a COVID-19 intensive care unit before evacuation, preserving forward surgical capability for battalion combat teams.

Conclusion

Far-forward surgical assets like GHOST have demonstrated their mobility and effectiveness in a casualty care system and could be adapted as critical care facilities to respond to the COVID crisis in wartime.

Extremity soft tissue coverage in the combat zone: use of pedicled flap transfers by the deployed orthopedic surgeon

BACKGROUND

In theaters of operation, military orthopedic surgeons have to deal with complex open extremity injuries and perform soft-tissue reconstruction on local patients who cannot be evacuated. Our objective was to evaluate the outcomes and discuss practical issues regarding the use of pedicled flap transfers performed in the combat zone on local national patients.

METHODS

A retrospective study was conducted on data from patients treated by a single orthopedic surgeon during four tours in Chad, Afghanistan and Mali between 2010 and 2017. All pedicled flap transfers performed on extremity soft-tissue defects were included, and two groups were analyzed: combat-related injuries (CRIs) and non-combat related injuries (NCRIs).

RESULTS

Forty-one patients with a mean age of 25.6 years were included. In total, 46 open injuries required flap coverage: 19 CRIs and 27 NCRIs. Twenty of these injuries were infected. The mean number of prior debridements was significantly higher in the CRIs group. Overall, 63 pedicled flap transfers were carried out: 15 muscle flaps, 35 local fasciocutaneous flaps and 13 distant fasciocutaneous flaps. The flap types used did not differ for CRIs or NCRIs. Complications included one flap failure, one partial flap necrosis and six deep infections. At the mean follow-up time of 71 days, limb salvage had been successful in 38 of the 41 cases. There were no significant differences between CRIs and NCRIs in terms of endpoint assessment.

CONCLUSIONS

Satisfying results can be achieved by simple pedicled flaps performed by orthopedic surgeons deployed in forward surgical units. Most complications were related to failure of bone infection treatment. The teaching of such basic reconstructive procedures should be part of the training for any military orthopedic surgeon.

A decade in the battlefield (2004-2014): A French military perspective on the high mortality associated with non-exclusively orthopedic or brain combat injuries

BACKGROUND

During the last few decades, French armed forces have regularly deployed in asymmetric conflicts. Surgical support for casualties of these conflicts occurs in NATO role 2 and 3 medical treatment facilities (MTF); definitive surgical care occurs in France following a strategic medical evacuation. The aim of this study was to describe the combat injury profile of these soldiers who presented with either non-exclusively orthopedic and/or brain injuries.

METHODS

This descriptive study is a retrospective analysis of the surgical management of French casualties performed in role 2 or 3 MTF in Afghanistan, Mali, Niger, Djibouti and the Central African Republic between January 2004 and December 2014.

RESULTS

One hundred patients were included. Forty had fragment wounds. The most severe lesions were of the head, neck or thorax. The average injury severity score (ISS) was 34.9 (IC 95% 29.8-40). 17 damage control procedures were performed. Thirty patients died with a mean ISS of 61 (IC 95% 56-67); 5 deaths were considered as preventable. The most frequent surgical procedures in the MTF were digestive (n=31) and thoracic surgery (n=19). Thirty patients needed second-look surgery in France; eleven had severe complications. No patient died following medical evacuation to France.

CONCLUSIONS

Results from this study indicated that the mortality following non-exclusively brain or orthopedic injuries remains high in modern asymmetric conflicts. Level of Evidence IV.

Application of the Masquelet technique in austere environments: experience from a French forward surgical unit deployed in Chad

PURPOSE

We sought to evaluate the results of the Masquelet-induced membrane technique (IMT) for long bone defect reconstruction within the limited-resource setting of a French forward surgical unit deployed in Chad.

METHODS

A prospective and observational study was conducted in all patients with a traumatic segmental bone defect in any anatomical location treated by IMT from November 2015 to December 2019. Although IMT was applied by various orthopedic surgeons with variable expertise, all followed the same surgical protocol. Endpoint assessment was performed 12 months after IMT application.

RESULTS

Sixteen patients with a mean age of 32.7 years were included in the study. Bone defects were located on the tibia (n = 8), the femur (n = 6) or the radius (n = 2). Thirteen bone defects were infected. After debridement, the mean bone defect length was 4.3 cm. External fixation of the tibia and femur was predominant in both stages. Bone union was achieved in only 8 of the 16 cases at a mean time of 7.6 months. All failures were related to persistent infection or insufficient fixation stability in the second stage.

CONCLUSIONS

This series is the first to report IMT use in a forward surgical unit. Despite frequent complications, local patients can benefit from this procedure, which is the only available method for bone reconstruction in areas with limited medical resources. A rigorous technical completion at both stages is crucial to limit septic or mechanical failures.

Evaluation of a fellowship abroad as part of the initial training of the French military surgeon

INTRODUCTION

Military surgery requires skills that in general cannot be easily learnt in civilian training. Participation in a fellowship abroad adapted to the particular operating conditions of the foreign deployment is one route that might secure the necessary supplementary training. We therefore assessed the relevance of such a fellowship in the preparedness of young military surgeons in their first deployment.

METHODS

This study included all active military surgeons who had completed a fellowship abroad during their initial training from 2004 to 2017 in Tchad or Senegal or Djibouti. The collection of data was performed using a questionnaire. The main judgement criterion was the rate of positive answers awarded to the relevance of this fellowship in the preparedness of respondents' first foreign deployment.

RESULTS

Sixty-nine of 73 surgeons answered. Sixty-one estimated the fellowship had allowed them to feel more operational during their first mission, with 83.61% rating this feeling as important. Also, 61 recommended the use of a fellowship for war surgery training. The grade assigned to the surgical benefit was 8.48/10.

CONCLUSION

A fellowship abroad permits one to become familiar with surgical practice under austere circumstances and the particularities of the surgical structures at the front. Current trainees' feedback confirms its relevance.

Surgical management of spine injuries in severe polytrauma patients: a retrospective study

Background: Optimal surgical management of spinal injuries as part of life-threatening multiple traumas remains challenging. We provide insights into the surgical management of spinal injuries in polytrauma patients. Methods: All patients from our polytrauma care network who both met at least one positive Vittel criteria and an injury severity score (ISS) >15 at admission and who underwent surgery for a spinal injury were included retrospectively. Demographic data, clinical data demonstrating the severity of the trauma and imaging defining the spinal and extraspinal number and types of injuries were collected.Results: Between January 2012 and December 2016, 302 (22.2%) patients suffered from spinal injury (143 total injuries) and 83 (6.1%) met the inclusion criteria. Mean ISS was 36.2 (16-75). Only 48 (33.6%) injuries led to neurological impairment involving the thoracic (n = 23, 16.1%) and lower cervical (n = 15, 10.5%) spine. The most frequent association of injuries involved the thoracic spine (n = 42). 106 spinal surgeries were performed. The 3-month mortality rate was 2.4%.Conclusions: We present data collected on admission and in the early postoperative period referring to injury severity, the priority of injuries, and development of multi-organ failure. We revealed trends to guide the surgical support of spinal lesions in polytrauma patients.

Terrorist threat: Creating a nationwide damage control training program for non-trauma care providers

INTRODUCTION

The current terrorist threat challenges nations to train numerous non-trauma care providers with different backgrounds in damage control (DC) strategies. The purpose of this work was to propose a specific DC training program.

METHODS

A Task Force of 16 civilian and military physicians met for a 24-hour session, to propose the construction of a DC training program for non-specialised caregivers.

RESULTS

Existing DC training programs are heterogeneous, mainly theoretical and almost only for physicians. A program entitled Damage Control for Terrorist Attack Victims (DC-TAV) was then proposed. Identified training targets were care providers from prehospital and hospital staffs, with no experience in trauma care. The training objectives were the improvement of individual and collective skills in managing terrorist attacks casualties. The tools selected for training concerned e-learning on a dedicated digital teaching platform (including a core section of four modules with types and mechanisms of injury, basic DC techniques, triage, organisation of emergency medical response and two complementary modules for doctors with DC resuscitation including remote transfusion and DC surgery), hands-on workshops with procedural simulation and full-scale simulation exercises, technical (tourniquets, haemostatic gauzes, needle thoracostomy, chest tube drainage, management of airway, coniotomy) and non-technical (leadership, communication, coordination and triage, decision-making, appropriate use of resources) skills. Finally, an evaluation of the DC-TAV program was planned.

CONCLUSIONS

The DC-TAV program is an ambitious, civilian-military, nationwide and long-term program, based on a harmonised standard of care and including multidimensional training. Further studies are required to assess its efficacy.

Australasian general surgical training and emergency medical teams: a review

Emergency medical teams (EMTs) have provided surgical care in sudden-onset disasters in low- and middle-income countries. General surgeons have been heavily involved in many EMTs due to their traditional broad set of surgical skills and experience. With the increased subspecialization of general surgical training in many high-income countries, including Australia and New Zealand, finding general surgeons with adequately broad experience is becoming more challenging. Furthermore, it is now considered standard for EMTs deploying to a sudden-onset disaster to have undergone credentialing, demonstrating sufficient training of their deployed members. The purpose of this review was to highlight the challenges and potential solutions facing those involved in training and recruiting general surgeons for EMTs in Australasia.

Deployment of the Surgical Life-saving Module (SLM) in 2017: Lessons learned in setting up and training operational surgical units

INTRODUCTION

The military operations carried out by the French armed forces, occasionally require the use of the Surgical Life-saving Module (SLM), to ensure the surgical support of its soldiers. Due to its extreme mobility and capacity of fast deployment, SLM is particularly useful in small-scale military operations, such as Special Forces missions. In 2017, the French SLM was for the first time used to ensure surgical support of allied forces, which were lacking forward surgical capabilities.

MATERIALS AND METHODS

the SLM is a mobile, heliborne, airborne, surgical structure with parachuting capability onto land or sea, therefore essentially focused on life-saving procedures, also known as "damage control" surgery. Due to the need for mobility and rapid implementation, the SLM is limited to a maximum of 5 interventions or, in terms of injuries, to 1 or 2 seriously injured patients.

RESULTS

Over a period of 2 months, 5 medical teams were successively deployed with the SLM. A total of 157 casualties were treated. The most common injuries were caused by shrapnel 561%), followed by firearms (36%), and blunt trauma (2.5%). Injuries included the limbs (56%), thorax (18%), abdomen (13%), head (11%), and neck (2%). The average ISS was 8.5 (1-25) with 26 patients presenting with an ISS greater than or equal to 15. The average NISS was 10.8 (1-75) with 34 casualties having an NISS equal to or greater than 15. The surgical procedures were broken down as follows: 126 dressings, 16 laparotomies, 7 thoracotomies, 12 isolated thoracic drains (without thoracotomy), 1 cervicotomy, 12 amputations, 7 limb splints, 2 limb fasciotomies, 2 external fixators and 1 femoral fracture traction.

CONCLUSIONS

The numerous SLM deployments in larger operations highlighted its ability to adapt both in terms of equipment and personnel. Continuous management of equipment logistics, robust personnel training, and appropriate organization of the evacuation procedures, were the key elements for optimizing combat casualty care. As a consequence, the SLM appears to be an operational surgical unit of choice during deployments.

Teaching courses in the management of visceral trauma

Several changes introduced in the management of trauma during the last two decades have considerably decreased the practical exposure to bleeding trauma patients by residents and young surgeons. Hemorrhage still represents the second cause of death from trauma worldwide, and the surgical maneuvers required for its control must be learned and practised in specific courses. These courses address the "second hour" of trauma, beyond ATLS^©, and also emphasize the decision-making process, communication among team members, and discussion of clinical scenarios. The significant progress made in simulation technologies and virtual reality systems have yet to replace living tissue models to train surgeons in the rapid control of active bleeding, although that replacement is probably not far away.

Skill sets required for the management of military head, face and neck trauma: a multidisciplinary consensus statement

Introduction

The evolution of medical practice is resulting in increasing subspecialisation, with head, face and neck (HFN) trauma in a civilian environment usually managed by a combination of surgical specialties working as a team. However, the full combination of HFN specialties commonly available in the NHS may not be available in future UK military-led operations, necessitating the identification of a group of skill sets that could be delivered by one or more deployed surgeons.

Method

A systematic review was undertaken to identify those surgical procedures performed to treat acute military head, face, neck and eye trauma. A multidisciplinary consensus group was convened following this with military HFN trauma expertise to define those procedures commonly required to conduct deployed, in-theatre HFN surgical combat trauma management.

Results

Head, face, neck and eye damage control surgical procedures were identified as comprising surgical cricothyroidotomy, cervico-facial haemorrhage control and decompression of orbital haemorrhage through lateral canthotomy. Acute in-theatre surgical skills required within 24 hours consist of wound debridement, surgical tracheostomy, decompressive craniectomy, intracranial pressure monitor placement, temporary facial fracture stabilisation for airway management or haemorrhage control and primary globe repair. Delayed in-theatre procedures required within 5 days prior to predicted evacuation encompass facial fracture fixation, delayed lateral canthotomy, evisceration, enucleation and eyelid repair.

Conclusions

The identification of those skill sets required for deployment is in keeping with the General Medical Council’s current drive towards credentialing consultants, by which a consultant surgeon’s capabilities in particular practice areas would be defined. Limited opportunities currently exist for trainees and consultants to gain experience in the management of traumatic head, face, neck and eye injuries seen in a kinetic combat environment. Predeployment training requires that the surgical techniques described in this paper are covered and should form the curriculum of future military-specific surgical fellowships. Relevant continued professional development will be necessary to maintain required clinical competency.

Management of war-related vascular wounds in French role 3 hospital during the Afghan campaign

OBJECTIVES

To describe the management of war-related vascular injuries in the Kabul French military hospital.

METHODS

From January 2009 to April 2013, in the Kabul French military hospital, we prospectively included all patients presenting with war-related vascular injuries. We collected the following data: site, type, and mechanism of vascular injury, associated trauma, type of vascular repair, amputation rate and complications.

RESULTS

Out of the 922 soldiers admitted for emergency surgical care, we recorded 45 (5%) patients presenting with vascular injuries: 30 (67%) gunshot-related, 11 (24%) explosive device-related, and 4 (9%) due to road traffic accident. The majority of injuries (93%) involved limbs. Vascular injuries were associated with fractures in 71% of cases. Twelve (26.7%) had an early amputation performed before evacuation. Twenty (44.4%) patients underwent fasciotomy and three (6.6%) sustained a compartment syndrome.

CONCLUSIONS

This was the first French reported series of war-related vascular injuries during the last decade's major conflicts. The majority of injuries occurred in the limbs. Autologous vein graft remains the treatment of choice for arterial repair. Functional severity of these injuries justifies specific training for military surgeons.

Concept and evaluation of the German War Surgery Course - Einsatzchirurgie-Kurs der Bundeswehr

INTRODUCTION

Military surgeons must be prepared to care for severe and complex life-threatening injuries rarely seen in the civilian setting. Typical civilian training and practice do not provide adequate exposure to the broad set of surgical skills required. The German Bundeswehr Medical Service has developed and refined the War Surgery Course (WSC) to meet this training gap. This article describes the recent experience with this readiness curriculum.

METHODS

Run annually since 1998, WSC consists nowadays of 5 days with 20 theoretical modules. Four sessions with standardised practical skills training use a live tissue porcine model, and the recently added cadaver-based Advanced Surgical Skills for Exposure in Trauma course. Sixteen military surgeons who participated in the WSC in January 2016 completed a survey of their self-rated readiness for 114 predefined emergency skills before and after completion, and provided an overall evaluation of the course.

RESULTS

Self-assessed readiness improved significantly over baseline for all areas covered in both the practical skills and theoretical knowledge portions of the WSC curriculum. Additionally, all participants rated the course as important and universally recommended it to other military surgeons preparing for missions.

CONCLUSIONS

The WSC course format was well received and perceived by learners as a valuable readiness platform. Ongoing evaluation of this course will enable data-driven evolution to ensure a maximum learning benefit for participants. With the increasing multinational nature of modern military missions, surgeons' training should follow international standards. Continuing evolution of military surgical training courses should further encourage the sharing and adoption of best educational practices.
