JOURNAL OF SURGICAL EDUCATION 2023; 80:1320-1339. [PMID: 37516576 DOI: 10.1016/j.jsurg.2023.06.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 05/11/2023] [Accepted: 06/17/2023] [Indexed: 07/31/2023]
Abstract
INTRODUCTION Live anaesthetized animals are used as simulation models to teach techniques in the emergency management of trauma. We aimed to explore how "live tissue training" (LTT) is designed, delivered and evaluated in order to better understand and characterize aspects of educational merit. METHODS A systematic review was performed using PRISMA guidance. A combined approach, involving a 3-stage modified narrative synthesis process and reflexive thematic analysis was used to identify key concepts across the published literature. FINDINGS Qualitative synthesis of 48 selected articles suggests that LTT is mainly used to teach military and civilian physicians and military medical technicians. The procedures trained vary with the learner population, from simple pre-hospital trauma tasks to advanced operative surgical skills. Many courses use a combination of didactic and practical training, with an animal model used to train practical application of knowledge and procedural skills. Descriptions of the learning interventions are limited, and explicit use of educational theory or pedagogic frameworks were absent within the literature. Four themes were identified regarding aspects of LTT that are valued by learners: "recreating the experience," relating to fidelity and realism; "tick tock" "dynamics of hemorrhage", encompassing the impact of bleeding and urgent pressure to act; "emotional impact" of conducting the training, and "self-efficacy: I believe I can do it." CONCLUSION Thematic analysis of published literature suggests that there may be educational benefit in the use of live tissue models due to time criticality and bleeding, which creates a real-life event. LTT also invokes an emotional response, and learners experience an increase in self-efficacy from participation. We consider that these aspects and associated pedagogy should be addressed when researching and developing alternative simulation modalities, in order to intelligently replace, reduce and refine the use of animals in training practitioners in the emergency management of trauma.

Abstract
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. World J Surg 2023; 47:1662-1683. [PMID: 36988651 DOI: 10.1007/s00268-023-06985-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/12/2023] [Indexed: 03/30/2023]
Abstract
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.

Human body donation and surgical training: a narrative review with global perspectives. Anat Sci Int 2023; 98:1-11. [PMID: 36227535 PMCID: PMC9845172 DOI: 10.1007/s12565-022-00689-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 10/06/2022] [Indexed: 02/01/2023]
Abstract
Utilization of human material in surgical simulation training has been well-established as an effective teaching method. Despite the value of donor-based surgical simulation training, its application may be hampered by difficulties regarding access to donated bodies. Therefore, the aim of this review is to assess body donation and body acquisition practices with regard to surgical simulation training programs around the world. The results of this review highlight discrepancies regarding body donation practices and surgical simulation programs among continents and countries. The utilization of donor bodies in surgical simulation appears to mirror body donation practices. In countries that rely mostly or exclusively upon unclaimed bodies or executed criminals, there are scant reports of donor-based surgical simulation programs. In countries where willed-body donation is the principal source of human material, there tend to be many surgical simulation programs that incorporate human material as part of surgical training. This review suggests that, in anatomical and surgical education, the utilization of active willed-body donation programs, as opposed to the utilization of unclaimed human bodies, positively corresponds with the development of beneficial donor-based surgical simulation programs. Likewise, donor-based surgical simulation training programs may have an influence on the perpetualization of willed-body donations.

Abstract
PURPOSE It is challenging to prepare military surgeons with the skills of combat damage control surgery (CDCS). The current study aimed to establish a damage control surgery (DCS) training platform for explosive combined thoraco-abdominal injuries. METHODS The training platform established in this study consisted of 3 main components: (1) A 50 m × 50 m square yard was constructed as the explosion site. Safety was assessed through cameras. (2) Sixteen pigs were injured by an explosion of trinitrotoluene attached with steel balls and were randomly divided into the DCS group (accepted DCS) and the control group (have not accepted DCS). The mortality rate was observed. (3) The literature was reviewed to identify the key factors for assessing CDCS, and testing standards for CDCS were then established. Expert questionnaires were employed to evaluate the scientificity and feasibility of the testing standards. Then, a 5-day training course with incorporated tests was used to test the efficacy of the established platform. In total, 30 teams attended the first training course. The scores that the trainees received before and after the training were compared. SPSS 11.0 was employed to analyze the results. RESULTS The high-speed video playback confirmed the safety of the explosion site as no explosion fragments projected beyond the wall. No pig died within 24 h when DCS was performed, while 7 pigs died in the control group. After a literature review, assessment criteria for CDCS were established that had a total score of 100 points and had 4 major parts: leadership and team cooperation, resuscitation, surgical procedure, and final outcome. Expert questionnaire results showed that the scientific score was 8.6 ± 1.25, and the feasibility score was 8.74 ± 1.19. When compared with the basic level, the trainees' score improved significantly after training. CONCLUSION The platform established in this study was useful for CDCS training.

Abstract
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.

Abstract
BACKGROUND In the Netherlands, each year a three-day international multidisciplinary trauma masterclass is organized to provide the knowledge and skills needed to care for critically injured trauma patients. This study was designed to longitudinally evaluate the effect of the course on participant's self-assessment of their own ability and confidence to perform general and specific skills. METHODS Between 2013 and 2016, all participants were invited to complete a questionnaire before and during follow-up. Participants were asked to self-assess their level of confidence to perform general skills (communication, teamwork, leadership) and specific skills. Mean scores were calculated, and mixed models were used to evaluate correlation. RESULTS We asked 265 participants to participate. Response rate was 64% for the pre-questionnaire, 63% for the post-questionnaire and for 3 months, 1 year and 2 years, respectively, 40%, 30%, 20%. The surgical group showed a statistically significant increase in self-assessed confidence for general skills (3.82-4.20) and specific technical skills (3.01-3.83; p < 0.001). In the anesthetic group, self-assessed confidence increased significantly in general skills (3.72-4.26) and specific technical skills (3.33-4.08; p < 0.001). For both groups statistical significance remained during follow-up. CONCLUSIONS This study demonstrated a sustained positive effect of a dedicated multidisciplinary trauma training curriculum on participant's self-assessed confidence to perform both general and specific technical skills necessary for the care of injured patients. Given the known association between confidence and competence, these findings provide evidence that dedicated trauma training curricula can provide positive lasting results. LEVEL OF EVIDENCE This is a basic science paper and therefore does not require a level of evidence.

Abstract
BACKGROUND Due to the increasing threat of terrorist attacks and assassinations even in Europe, the interest in management of severe vascular injuries, which, with an increased incidence of 10% are to be expected with such penetrating wounds, is also growing; however, with increasing subspecialization in surgery there is a threat that the know-how in vascular surgery will become lost among non-vascular surgical specialists. Therefore, the Germany military established an educational program, the so-called DUOplus concept, to ensure that future military surgeons acquire and retain the experience and skills to fulfill the demanding role of a deployed surgeon. OBJECTIVE The DUOplus concept of the German Medical Forces is introduced with a special focus on vascular surgery training. RESULTS All trainee German military surgeons attain a second specialization alongside general surgery. This residency includes several courses in various surgical specialties as well as a 12-month rotation in a vascular surgery department. The core elements of vascular trauma training are two practical courses on life-like models. In these courses, which were developed especially for the needs of non-vascular surgeons in hands-on training, open surgical techniques and damage control measures including resuscitative endovascular balloon occlusion of the aorta (REBOA) are taught on suitable models and intensively practiced. CONCLUSION All surgeons potentially confronted with traumatic and iatrogenic vascular injuries should have some basic competence in the management of vascular trauma. Especially the courses in vascular surgery for non-vascular surgeons offer such a skill set for every surgeon. Next to the German military surgeons, the courses are attended more and more by civilian and military surgeons from different surgical specialties and nationalities.
