Paediatric mass casualty response through the lens of Functional Resonance Analytical Methodology- lessons learned.

BACKGROUND: Mass Casualty Incidents are rare but can significantly stress healthcare systems. Functional Resonance Analytical Methodology (FRAM) is a systematic approach to model and explore how complex systems adapt to variations and to understand resilient properties in the face of perturbations. The aim of this study was to use FRAM to create a model of a paediatric trauma system during the initial response to the Manchester Arena Attack to provide resilience-based insights for the management of future Mass Casualty Incidents (MCI). METHODS: Qualitative interviews in the immediate aftermath of a terrorist bombing, were followed up with further in-depth probing of subject matter experts to create a validated and verified FRAM model. This model was compared with real incident data, then simplified for future studies. RESULTS: A Work As Imagined (WAI) model of how a paediatric emergency department provided resilient healthcare for MCI patients from reception and resuscitation to definitive care is presented. A focused model exploring the pathway for the most severely injured patients that will facilitate the simulation of a myriad of potential emergency preparedness resilience response scenarios is also presented. CONCLUSIONS: The systematic approach undertaken in this study has produced a model of a paediatric trauma system during the initial response to the Manchester Arena Attack, providing key insights on how a resilient performance was sustained. This modelling may provide an important step forward in the preparedness and planning for future MCIs.

Impacting trauma care in resource-limited settings: Lessons learned from Tanzania's web-based trauma registry initiatives.

BACKGROUND: Trauma significantly impacts Tanzanian healthcare. Lacking standardized hospital-based minimal trauma data sets places further challenges for policymakers. In other resource-limited countries, implementing trauma systems and registries has reduced injury mortalities. In 2013, we introduced an electronic trauma registry, iTRAUMATM at the Tanzanian Muhimbili Orthopedic Institute (MOI) but noted several drawbacks. In 2023, we introduced a robust web-based trauma registry platform. This study assesses the feasibility and utility of implementing the platform at MOI and summarizes challenges, lessons, and results compared to existing systems. METHODS: This prospective observational study involved clinicians collecting data directly on the platform at the point-of-care, following specific training. Semi-structured interviews with local stakeholders identified challenges and areas for improvement. Data were reported from July to December 2023. RESULTS: Data from 2930 patients showed 59% of injuries were from road traffic collisions (RTCs), with 43% of patients arriving at MOI by non-ambulances. Our findings show that non-ambulance arrivals were associated with higher injury severity (p < 0.026), mortalities (p < 0.017), and delayed hospital arrival (p < 0.004), underscoring the critical role of prompt transport in trauma management. The new platform identified trauma care gaps, with a mean arrival-to-care time of 29.89 min, prompting trauma training at MOI to enhance clinician capacities. It also demonstrated superiority over existing systems by improving data completeness, timeliness, and usability. Challenges included gaining support for the platform's functionality, technology integration, and navigating administrative changes. With continued communication, stakeholder acceptance and support were achieved. CONCLUSION: The web-based platform has become MOI's standard trauma database, demonstrating its feasibility and utility. It overcame the existing challenges of data completeness, timeliness, and usability for policymaking. Positive feedback has prompted plans to expand the platform to other hospitals, benefiting clinical benchmarking and trauma preventive efforts. Ensuring sustainability requires involvement from the Ministry of Health, ongoing training, functionality enhancements, and strengthened global partnerships.

Isolated Lung Ventilation With Tracheostomy Using Two Intubation Tubes for Severe Endotracheal Hemorrhage Due to Pulmonary Contusion.

A 72-year-old man presented with severe pulmonary contusions and multiple traumas, including aortic injury, pelvic fracture, and renal injury. The patient required multidisciplinary treatment, including transcatheter arterial embolization, thoracic endovascular aortic repair, right lung upper lobe partial resection, and massive transfusion. During the initial treatment, the patient experienced respiratory failure due to endotracheal bleeding, and we attempted isolated lung ventilation with a 37 Fr double-lumen endotracheal intubation tube. Although drainage by suction and protection of the healthy lung was vital, the patient was unable to maintain ventilation volume because of poor drainage. Additionally, the respiratory status deteriorated. To resolve the situation, a tracheotomy was performed and two endotracheal intubation tubes (6.0 mm inner diameter, and 9.0 mm outer diameter) were inserted through a large U-shaped tracheal hole 18 hours after admission. The respiratory status of the patient gradually improved after the procedure. There were two advantages of this method of respiratory management. Firstly, each of the two endotracheal tubes had a separate cuff, allowing more reliable separation of the healthy lung from the injured lung. Secondly, bronchoscopes of sufficient diameter (4.9 mm outer diameter ) were used bilaterally, allowing sufficient drainage of viscous airway secretions mixed with hematoma and improving atelectasis. Although venovenous extracorporeal membrane oxygenation is a crucial support tool when the respiratory status deteriorates due to severe pulmonary contusions, our method of airway management may be attempted in patients with multiple traumatic injuries with coagulopathy.

Association of trauma classifications to long-term outcome in blunt trauma patients.

PURPOSE: The impact of major trauma is long lasting. Although polytrauma patients are currently identified with the Berlin polytrauma criteria, data on long-term outcomes are not available. In this study, we evaluated the association of trauma classification with long-term outcome in blunt-trauma patients. METHODS: A trauma registry of a level I trauma centre was used for patient identification from 1.1.2006 to 31.12.2015. Patients were grouped as follows: (1) all severely injured trauma patients; (2) all severely injured polytrauma patients; 2a) severely injured patients with AIS ≥ 3 on two different body regions (Berlin-); 2b) severely injured patients with polytrauma and a physiological criterion (Berlin+); and (3) a non-polytrauma group. Kaplan-Meier survival analysis was performed to estimate differences in mortality between different groups. RESULTS: We identified 3359 trauma patients for this study. Non-polytrauma was the largest group (2380 [70.9%] patients). A total of 500 (14.9%) patients fulfilled the criteria for Berlin + definition, leaving 479 (14.3%) polytrauma patients in Berlin- group. Berlin + patients had the highest short-term mortality compared with other groups, although the difference in cumulative mortality gradually plateaued compared with the non-polytrauma patient group; at the end of the 10-year follow up, the non-polytrauma group had the greatest mortality due to the high number of patients with traumatic brain injury (TBI). CONCLUSION: Excess mortality of polytrauma patients by Berlin definition occurs in the early phase (30-day mortality) and late deaths are rare. TBI causes high early mortality followed by increased long-term mortality.

Blood far forward: A cross-sectional analysis of prehospital transfusion practices in the Canadian Armed Forces.

BACKGROUND: Canadian Armed Forces (CAF) operate in environments that challenge patient care, especially trauma. Military personnel often find themselves in remote settings without conventional healthcare facilities. Treating traumatic injuries, particularly hemorrhagic shock, often necessitates prehospital blood transfusion. This study aims to present an overview of the current CAF prehospital transfusion practices. Furthermore, the study compared current and developing protocols against expert-recommended guidelines. METHODS: A cross-sectional survey design was employed to describe and compare CAF prehospital blood transfusion practices and protocols against expert recommendations. Topics included protocols, equipment, and procedures. An online survey targeted medical leadership and providers within CAF, with data collected from August 15 to December 15, 2023. Results were summarized descriptively. This study received approval from the Unity Health Toronto Research Ethics Board (REB 23-087). RESULTS: Units and teams with prehospital blood transfusion capabilities were contacted, achieving a 100 % response rate. Within CAF, Canadian Special Operations Forces Command (CANSOFCOM), Mobile Surgical Resuscitation Team (MSRT), and Canadian Medical Emergency Response Team (CMERT) possess these capabilities, established between 2013 and 2018. These programs are crucial for military operations. CAF has access to standard blood components, cold Leuko-Reduced Whole Blood (LrWB), and factor concentrates from Canadian Blood Services (CBS), available for both domestic and international missions given adequate planning and favorable conditions. Key findings indicate high adherence to recommended practices, some variability in the transfusion process, and potential benefits of standardizing prehospital transfusion practices. CONCLUSIONS: This study provided insights into CAF's implementation of prehospital transfusion practices, highlighting high adherence to national expert recommendations and the importance of structured protocols in military prehospital trauma management. IMPLICATIONS OF KEY FINDINGS: CAF's approach and adoption of prehospital transfusion protocols lay a strong foundation for managing trauma patients in remote settings and for expanding prehospital transfusion capabilities across CFHS deployed assets. Further research is needed to advance military trauma care by adapting prehospital blood transfusion to dynamic tactical landscapes and evolving technologies.

Prehospital treatment of severely burned patients: a retrospective analysis of patients admitted to the Berlin burn centre.

BACKGROUND: Prehospital management of severely burned patients is extremely challenging. It should include adequate analgesia, decision-making on the necessity of prehospital endotracheal intubation and the administration of crystalloid fluids. Guidelines recommend immediate transport to specialised burn centres when certain criteria are met. To date, there is still insufficient knowledge on the characteristics of prehospital emergency treatment. We sought to investigate the current practice and its potential effects on patient outcome. METHODS: We conducted a single centre, retrospective cohort analysis of severely burned patients (total burned surface area > 20%), admitted to the Berlin burn centre between 2014 and 2019. The relevant data was extracted from Emergency Medical Service reports and digital patient charts for exploratory data analysis. Primary outcome was 28-day-mortality. RESULTS: Ninety patients (male/female 60/30, with a median age of 52 years [interquartile range, IQR 37-63], median total burned surface area 36% [IQR 25-51] and median body mass index 26.56 kg/m2 [IQR 22.86-30.86] were included. The median time from trauma to ED arrival was 1 h 45 min; within this time, on average 1961 ml of crystalloid fluid (0.48 ml/kg/%TBSA, IQR 0.32-0.86) was administered. Most patients received opioid-based analgesia. Times from trauma to ED arrival were longer for patients who were intubated. Neither excessive fluid treatment (> 1000 ml/h) nor transport times > 2 h was associated with higher mortality. A total of 31 patients (34,4%) died within the hospital stay. Multivariate regression analysis revealed that non-survival was linked to age > 65 years (odds ratio (OR) 3.5, 95% CI: 1.27-9.66), inhalation injury (OR 3.57, 95% CI: 1.36-9.36), burned surface area > 60% (OR 5.14, 95% CI 1.57-16.84) and prehospital intubation (5.38, 95% CI: 1.92-15.92). CONCLUSION: We showed that severely burned patients frequently received excessive fluid administration prehospitally and that this was not associated with more hemodynamic stability or outcome. In our cohort, patients were frequently intubated prehospitally, which was associated with increased mortality rates. Further research and emergency medical staff training should focus on adequate fluid application and cautious decision-making on the risks and benefits of prehospital intubation.

Navigating the 'Triangle of Death': A Multidisciplinary Approach in Severe Multi-Trauma Management.

This case report details the challenging management of a 45-year-old male construction worker who suffered severe multiple injuries after a fall and subsequent collision with cement mixers. The patient presented with extensive injuries, including amputation, fractures and internal bleeding, leading to a state known as the 'triangle of death'. Despite the initial grim prognosis, evidenced by an ISS score of 28 and a mortality risk coefficient of 89.56%, the patient was successfully resuscitated and managed through a multidisciplinary approach. This included damage control resuscitation, emergency vascular interventions and targeted temperature management for brain protection. The patient's recovery highlights the effectiveness of comprehensive trauma management and the critical role of coordinated care in severe multi-trauma cases.

A Rare Case of Transepiphyseal Distal Femur Fracture Dislocation With Delayed Recovery of a Common Peroneal Nerve Injury.

The aim of this study is to bring attention to a unique case and our approach to treatment in this context. We describe a case of an 11-year-old male who presented to us with an injury to his left knee following trauma with pain, swelling, shortening and deformity for one day. An X-ray revealed a transepiphyseal fracture dislocation of the left distal femur (Salter-Harris type 1 injury) and neurovascular examination was conclusive of foot drop which pointed towards injury to common peroneal nerve (CPN). The patient was taken up for closed reduction with percutaneous pinning under mobile C-arm guidance. The fracture was reduced and fixed with two cross K-wires and immobilized with the above knee anterior-posterior slab for six weeks. The wires were removed after six weeks but there was no improvement in the dorsiflexion of the left ankle. An electromyography (EMG) and nerve conduction velocity (NCV) study test was performed after 12 weeks which showed decreased amplitude and prolonged latency in the left CPN with early denervation of the muscles supplied by the left CPN. Fifteen weeks of follow-up showed complete recovery in the dorsiflexion of the left ankle with a slight lag in the extension of the left great toe making this an unusually delayed recovery of CPN palsy following a distal femur transepiphyseal fracture.

Predictive Energy Equations Inaccurately Estimate Metabolic Demands of Older Adult Trauma Patients.

INTRODUCTION: Suboptimal nutrition promotes unfavorable outcomes in trauma patients, particularly among those aged 60 and over. While many institutions employ predictive energy equations to determine patients' energy requirements, mounting evidence shows these equations inaccurately estimate caloric needs. In this pilot randomized controlled trial, we sought to quantify the discrepancy between predictive equations and indirect calorimetry (IC)-the gold standard for determining energy requirements-in the older adult trauma population. METHODS: This is a nested cohort study within a pilot randomized control trial in which 32 older adult trauma patients were randomized 3:1 to receive IC-guided nutrition delivery versus standard of care. IC requirements of patients in the intervention arm were compared to Mifflin St. Jeor (MSJ), Harris-Benedict (HB), and the American Society for Parenteral and Enteral Nutrition-Society of Critical Care Medicine (ASPEN-SCCM) predictive energy equations. RESULTS: Twenty patients underwent IC to assess measured resting energy expenditure (mREE), yielding a mean (standard deviation) mREE of 23.1 ± 4.8 kcal/kg/d. MSJ and HB gave mean predictive resting energy expenditures of 17.5 ± 2.0 and 18.5 ± 2.0 kcal/kg/d in these patients, demonstrating that IC-derived values were 32.1% and 25.0% higher, respectively. When patients were stratified by body mass index (BMI), MSJ, and HB more severely underestimated caloric requirements in individuals with BMI <30 versus BMI 30-50. While the mean mREE fell within the mean predictive resting energy expenditure range prescribed by ASPEN-SCCM equations (21.4 ± 4.1 to 26.2 ± 4.3 kcal/kg/d), individuals' IC-derived values fell within their personal range in 8 of 20 cases. CONCLUSIONS: The MSJ and HB predictive energy equations consistently and significantly underpredict metabolic demands of older adult trauma patients compared to IC and perform worse in lower BMI individuals. ASPEN-SCCM equations frequently overpredict or underpredict resting energy expenditure. While these findings should be confirmed in a larger randomized control trial, this study suggests that institutions should prioritize IC to accurately identify the metabolic demands of older trauma patients.

Application of Nerve Blocks in Upper and Lower Extremity Trauma Patients Presenting to the Emergency Department of a Tertiary Care Hospital: A Prospective Observational Study.

Background Pain related to trauma is often severe and undergoes undertreated in many patients. Peripheral nerve blocks provide analgesia, which is site-specific and devoid of any systemic adverse effects. Regional anesthesia may also confer several other advantages including decreased length of stay in the emergency department and improved comfort and safety for emergency procedures compared to conventional analgesia. This study aims to evaluate the feasibility of the application of nerve blocks in upper and lower extremity trauma patients presenting to the Emergency Department of a tertiary care hospital. Methodology We conducted a prospective observational study in the Department of Emergency Medicine (EM) at Dr. D. Y. Patil Medical College, Hospital & Research Centre, Pimpri, Pune between 2023 and 2024. As a part of this research proposal, we intended to study the application of nerve blocks in upper and lower extremity trauma among patients presenting with upper and lower extremity trauma to the ED during the study period. After institutional Ethics Committee approval and informed written consent, 95 patients aged above 18 years presenting with upper and lower extremity trauma within 12 hours were selected. Patients under 18 years old, those with a history of coagulopathies, patients with open fractures, and pregnant patients were excluded from the study. Results The study comprised 95 participants, with diverse age groups represented. Among them, 26% were under 25 years old, 54% fell between the ages of 26 and 30, and 20% were over 30 years old. Gender distribution showed 64.2% male and 35.8% female participants. In terms of injury nature, the majority experienced injuries from motor vehicle crashes (31.5%) and domestic incidents (22.1%), followed by workplace injuries (15.8%), sports injuries (14.7%), falls from heights (7.4%), and assault (7.4%). The time required for interventions varied, with 41.1% of cases completed in five minutes or less, while in 58.9% of instances, more than five minutes were necessary. Similarly, the time taken for pain relief post-intervention was reported, with 66.3% experiencing relief within five minutes and 33.7% requiring more than five minutes. On initial presentation, the mean VAS score was 8.8 with an SD of 1.1, indicating high levels of pain. Following the block, there was a significant reduction in pain, with the mean VAS score dropping to 1.9 and an SD of 1.2. This change was statistically significant with a p-value of less than 0.001, indicating a substantial improvement in pain levels post-block administration. Regarding the duration of pain relief, a similar pattern emerged, with 77.8% reporting relief lasting three hours or less, and 22.2% experiencing relief for more than three hours. Conclusion In emergency situations, our research showed that peripheral nerve blocks are a very useful tool for treating pain from trauma to the upper and lower extremities. These blocks significantly reduce pain and have a long-lasting effect. Further research with larger, multi-center trials is needed to validate these findings and explore long-term outcomes.

Legacy of Compassion: The Life and Contributions of Dr. Ronald Joseph Garst in Advancing Orthopaedic Surgery in Bangladesh.

Dr. Ronald Joseph Garst, a distinguished spine surgeon and missionary, significantly impacted the field of orthopaedic surgery in Bangladesh, especially during and after the country's Liberation War, when the nation had no orthopaedic specialists. His experiences during Bangladesh's struggle for independence inspired him to establish rehabilitation centers for injured freedom fighters and to found the Rehabilitation Institute and Hospital for the Disabled (RIHD), which later became the National Institute of Traumatology and Orthopaedic Rehabilitation (NITOR), Bangladesh's first tertiary-level trauma center. In Bangladesh, Dr. Garst was critical in organizing care for injured freedom fighters, setting up a central limb and brace center, and launching a post-graduate training program for orthopaedics, physiotherapists, and occupational therapists. He successfully raised funds, attracted international support, and provided essential training to Bangladeshi doctors, nurses, and limb-makers.  Dr. Garst's legacy extends beyond his medical achievements; his humanitarian spirit and dedication to helping the underprivileged earned him honorary citizenship in Bangladesh. He remained committed to supporting ongoing efforts at RIHD, frequently visiting Bangladesh and contributing equipment and training materials until his passing. Dr. Garst's contributions, such as initiating morning academic sessions at RIHD, continue to influence the orthopaedic community in Bangladesh. This article explores Dr. Garst's remarkable journey, his influence on orthopaedic surgery in Bangladesh, and the enduring impact of his work.

Using the Kirkpatrick Model to Evaluate the Effect of a Primary Trauma Care Course on Health Care Workers' Knowledge, Attitude, and Practice in Two Vietnamese Local Hospitals: Prospective Intervention Study.

Background: The Primary Trauma Care (PTC) course was originally developed to instruct health care workers in the management of patients with severe injuries in low- and middle-income countries (LMICs) with limited medical resources. PTC has now been taught for more than 25 years. Many studies have demonstrated that the 2-day PTC workshop is useful and informative to frontline health staff and has helped improve knowledge and confidence in trauma management; however, there is little evidence of the effect of the course on changes in clinical practice. The Kirkpatrick model (KM) and the knowledge, attitude, and practice (KAP) model are effective methods to evaluate this question. Objective: The aim of this study was to investigate how the 2-day PTC course impacts the satisfaction, knowledge, and skills of health care workers in 2 Vietnamese hospitals using a conceptual framework incorporating the KAP model and the 4-level KM as evaluation tools. Methods: The PTC course was delivered over 2 days in the emergency departments (EDs) of Thanh Hoa and Ninh Binh hospitals in February and March 2022, respectively. This study followed a prospective pre- and postintervention design. We used validated instruments to assess the participants' satisfaction, knowledge, and skills before, immediately after, and 6 months after course delivery. The Fisher exact test and the Wilcoxon matched-pairs signed rank test were used to compare the percentages and mean scores at the pretest, posttest, and 6-month postcourse follow-up time points among course participants. Results: A total of 80 health care staff members attended the 2-day PTC course and nearly 100% of the participants were satisfied with the course. At level 2 of the KM (knowledge), the scores on multiple-choice questions and the confidence matrix improved significantly from 60% to 77% and from 59% to 71%, respectively (P<.001), and these improvements were seen in both subgroups (nurses and doctors). The focus of level 3 was on practice, demonstrating a significant incremental change, with scenarios checklist points increasing from a mean of 5.9 (SD 1.9) to 9.0 (SD 0.9) and bedside clinical checklist points increasing from a mean of 5 (SD 1.5) to 8.3 (SD 0.8) (both P<.001). At the 6-month follow-up, the scores for multiple-choice questions, the confidence matrix, and scenarios checklist all remained unchanged, except for the multiple-choice question score in the nurse subgroup (P=.005). Conclusions: The PTC course undertaken in 2 local hospitals in Vietnam was successful in demonstrating improvements at 3 levels of the KM for ED health care staff. The improvements in the confidence matrix and scenarios checklist were maintained for at least 6 months after the course. PTC courses should be effective in providing and sustaining improvement in knowledge and trauma care practice in other LMICs such as Vietnam.

Trauma resulting in rare avulsion-type renal injury and lobe migration: An uncommon case report.

In this case report, we discuss a rare incident of avulsion-type renal injury in a 24-year-old male with no significant medical history. The injury occurred during a traffic accident, where he was involved in a direct impact collision between a motorcycle and a vehicle, leading to altered corticomedullary differentiation in the right kidney, a retroperitoneal hematoma, and free fluid in the cavity. The patient underwent successful emergency abdominal surgery, which involved the removal of the damaged kidney due to the severity of the injury. During his postoperative recovery in the ICU, he received extensive care, including sedation, mechanical ventilation, and vasopressor support. Ultimately, he made a successful recovery and was discharged after rehabilitation. This case highlights the complexities involved in managing patients with renal injuries resulting from high-energy impact accidents. It emphasizes the importance of a multidisciplinary approach in treatment, the challenges associated with deciding on surgical intervention, and the significance of rehabilitation in patient recovery. The uniqueness of this case, characterized by its distinct mechanism of injury and the severity of the trauma, contributes to our broader understanding of renal trauma management in the field of trauma medicine. It underscores the need for personalized patient care strategies and emphasizes the effectiveness of surgical interventions in severe cases of renal trauma.

A randomized trial of collaborative support for opioid taper after trauma hospitalization.

The COTAT (Collaborative Opioid Taper After Trauma) Study was a randomized trial of an opioid taper support program using a physician assistant (PA) to provide pain and opioid treatment guidance to primary care providers assuming care for adult patients with moderate to severe trauma discharged from a Level I trauma center on opioid therapy. Patients were recruited, assessed, and randomized individually by a surgery research recruitment team one to two days prior to discharge to home. Participants randomized to the opioid taper support program were contacted by phone within a few days of discharge by the PA interventionist to confirm enrollment and their primary care provider (PCP). The intervention consisted of PA support as needed to the PCP concerning pain and opioid care at weeks 1, 2, 4, 8, 12, 16, and 20 after discharge or until the PCP office indicated they no longer needed support or the patient had tapered off opioids. The PA was supervised by a pain physician-psychiatrist, a family physician, and a trauma surgeon. Patients randomized to usual care received standard hospital discharge instructions and written information on managing opioid medications after discharge. Trial results were analyzed using repeated measures analysis. 37 participants were randomized to the intervention and 36 were randomized to usual care. The primary outcomes of the trial were pain, enjoyment, general activity (PEG score) and mean daily opioid dose at 3 and 6 months after hospital discharge. Treatment was unblinded but assessment was blinded. No significant differences in PEG or opioid outcomes were noted at either time point. Physical function at 3 and 6 months and pain interference at 6 months were significantly better in the usual care group. No significant harms of the intervention were noted. COVID-19 (corona virus 2019) limited recruitment of high-risk opioid tolerant subjects, and limited contact between the PA interventionist and the participants and the PCPs. Our opioid taper support program failed to improve opioid and pain outcomes, since both control and intervention groups tapered opioids and improved PEG scores after discharge. Future trials of post-trauma opioid taper support with populations at higher risk of persistent opioid use are needed. This trial is registered at clinicaltrials.gov under NCT04275258 19/02/2020. This trial was funded by a grant from the Centers for Disease Control and Prevention to the University of Washington Harborview Injury Prevention & Research Center (R49 CE003087, PI: Monica S. Vavilala, MD). The funder had no role in the analysis or interpretation of the data.

The Effect of Critical Task Auto-failure Criteria on Medical Evaluation Methods in the Pararescue Schoolhouse.

BACKGROUND: Medical training and evaluation are important for mission readiness in the pararescue career field. Because evaluation methods are not standardized, evaluation methods must align with training objectives. We propose an alternative evaluation method and discuss relevant factors when designing military medical evaluation metrics. METHODS: We compared two evaluation methods, the traditional checklist (TC) method used in the pararescue apprentice course and an alternative weighted checklist (AWC) method like that used at the U.S. Army static line jumpmaster course. The AWC allows up to two minor errors, while critical task errors result in autofailure. We recorded 168 medical scenarios during two Apprentice course classes and retroactively compared the two evaluation methods. RESULTS: Despite the possibility of auto-failure with the AWC, there was no significant difference between the two evaluation methods, and both showed similar overall pass rates (TC=50% pass, AWC=48.8% pass, p=.41). The two evaluation methods yielded the same result for 147 out of 168 scenarios (87.5%). CONCLUSIONS: The AWC method strongly emphasizes critical tasks without significantly increasing failures. It may provide additional benefits by being more closely aligned with our training objectives while providing quantifiable data for a longitudinal review of student performance.

Mucormycosis Superinfection of a Chemical Burn.

Mucormycosis is an uncommon infection but is increasing in prevalence. Cutaneous disease is associated with burns and traumatic injuries. Cutaneous mucormycosis is the least deadly form but mortality is still approximately 36%. Burn superinfection with mucormycosis is increasingly common and can be an insidious process that may not present until the disease disseminates. We present the case of a 30-year-old male who presented to the emergency department for a rash. A rash with yellow crusting was noted to involve his scalp, face, ear, right shoulder, and parts of both feet. He had been placed on antibiotics by an urgent care a few days prior to presenting. He denied systemic symptoms, chemical exposure, change in detergent, autoimmune diseases, or travel. The patient has a history of intravenous opioid and dissociative abuse and had multiple episodes of syncope-including at his work in a factory where there were hot metals, refrigerants, and numerous corrosive chemicals. Surgical debridement revealed mucormycosis on pathology. The patient was treated with isavuconazole, surgical debridement, and skin grafting. He experienced complete recovery.

Approach and management of patients injured by bullfighting trauma. / Abordaje y manejo médico-quirúrgico del paciente herido por traumatismo taurino.

INTRODUCTION: Bullfighting festivals are attributed to the cultural idiosyncrasies of the Ibero-American people, posing an extreme risk to the physical integrity of the participants. Spain is considered the country with the highest number of bull-related celebrations worldwide and, therefore, with the highest number of patients injured by bullfighting trauma treated, thus justifying a public health problem. The generalities associated with this type of trauma define the people injured as polytraumatised patients. In addition, it is important to know the kinematics of the injuries and their specific characteristics, in order to implement quality medical-surgical care. METHODS: scientific review of the literature to promote a comprehensive guide for the medical-surgical management of patients injured by bullfighting trauma. RESULTS: We described the guidelines to standardise protocols for in-hospital approach of patients injured by bullfighting trauma. CONCLUSIONS: Bullfighting trauma is considered a real health problem in the emergency departments of the ibero-Americans countries, especially in Spain, where bullfighting is part of the national culture. The inherent characteristics of these animals cause injuries with special aspects, so it is important to know the generalities of bullfighting trauma. Because of the multidisciplinary approach, this guidelines are adressed to all healthcare providers involved in the management of these patients. It is essential to establish particular initial care for this type of injury, specific therapeutic action and follow-up based on the medical-surgical management of the trauma patient in order to reduce the associated morbidity and mortality.

Enhancing trauma care through innovative trauma and disaster team response training: A blended learning approach in Tanzania.

BACKGROUND: In Tanzania, inadequate infrastructures and shortages of trauma-response training exacerbate trauma-related fatalities. McGill University's Centre for Global Surgery introduced the Trauma and Disaster Team Response course (TDTR) to address these challenges. This study assesses the impact of simulation-based TDTR training on care providers' knowledge/skills and healthcare processes to enhance patient outcomes. METHODS: The study used a pre-post-interventional design. TDTR, led by Tanzanian instructors at Muhimbili Orthopedic Institute from August 16-18, 2023, involved 22 participants in blended online and in-person approaches with simulated skills sessions. Validated tools assessed participants' knowledge/skills and teamwork pre/post-interventions, alongside feedback surveys. Outcome measures included evaluating 24-h emergency department patient arrival-to-care time pre-/post-TDTR interventions, analyzed using parametric and non-parametric tests based on data distributions. RESULTS: Participants' self-assessment skills significantly improved (median increase from 34 to 58, p < 0.001), along with teamwork (median increase from 44.5 to 87.5, p < 0.003). While 99% of participants expressed satisfaction with TDTR meeting their expectations, 97% were interested in teaching future sessions. The six-month post-intervention arrival-to-care time significantly decreased from 29 to 13 min, indicating a 55.17% improvement (p < 0.004). The intervention led to fewer ward admissions (35.26% from 51.67%) and more directed to operating theaters (29.83% from 16.85%), suggesting improved patient management (p < 0.018). CONCLUSION: The study confirmed surgical skills training effectiveness in Tanzanian settings, highlighting TDTR's role in improving teamwork and healthcare processes that enhanced patient outcomes. To sustain progress and empower independent trauma educators, ongoing refresher sessions and expanding TDTR across low- and middle-income countries are recommended to align with global surgery goals.

A Retrospective Analysis of Needle Thoracostomies at a Tertiary Level 2 Trauma Center.

BACKGROUND: A tension pneumothorax is a condition that results in elevated pressure within the pleural space. The effective management of tension pneumothorax relies on needle decompression, commonly performed at the second intercostal space (ICS) midclavicular line (MCL). However, some literature suggests that catheters placed in the second intercostal space midclavicular line are prone to higher failure rates compared to the fifth intercostal space midaxillary line (MAL) (42.5% versus 16.7%, respectively). In this study, we aim to identify and scrutinize the prevalence of prehospital needle decompression from one tertiary care center over eight years and examine their trends, efficacies, or pitfalls. It is hypothesized that preclinical providers are performing needle decompression prematurely and unnecessarily. METHODS: A set of 90 patient records obtained using the trauma registry at Saint Francis Hospital, Tulsa, Oklahoma, were retrospectively reviewed to evaluate the management and outcomes of tension pneumothorax, as well as the indications documented for needle decompression. Patient charts were reviewed via Epic Hyperspace (Epic, Madison, WI). The Oklahoma Emergency Medical Service Information System (OKEMSIS) also provided information contributing to the sample population. RESULTS: The most documented indications for needle decompressions included diminished or absent breath sounds (52.70%), hypoxia (15.54%), hypotension, and hemodynamic instability (6.76%). Emergency medical services (EMS) reported improvements in 51 (56.67%) patients after needle thoracostomy. Improvements in vital signs after needle decompression were sporadic. The most common complication was catheter dislodging, which occurred most in the second intercostal space midclavicular line. Only nine patients had an oxygen saturation (SpO2) below 92% and a systolic blood pressure (SBP) below 100 mm Hg prior to receiving needle decompression. CONCLUSION: Current practices for tension pneumothorax show little improvement in vital signs before and after needle decompression. Vital signs prior to needle decompression often do not indicate tension pneumothorax physiology. Preclinical providers may be inappropriately performing needle decompressions, an invasive procedure with complications.
