ATLS: past, present, and future

Predictive Factors for Failure of Limb Salvage in Blunt Leg Trauma Associated with Vascular Injuries

Introduction:

Blunt leg trauma is common; however, it is rarely associated with significant vascular injury. This study was undertaken to determine the risk factors attributed to failure of limb salvage in acute postoperative period in blunt leg trauma with vascular injuries after revascularization.

Methods:

A retrospective analysis was conducted of all patients with blunt leg trauma involving bone and soft tissue associated with vascular injuries. They were studied in terms of demographic data, associated comorbidities, mechanism of trauma, associated extra leg injuries, type and nature of bone fractures, soft-tissue injuries, nerve injuries, time of ischemia, Injury Severity Score (ISS), Mangled Extremity Severity Score (MESS), injured vascular segments, modality of vascular repair, modality of bone fixation, thrombosis at the site of vascular repair, complications, limb salvage failure, and mortality.

Results:

Vascular injuries were identified in 45 arterial segments and 9 popliteal veins among 31 patients. The patients were 93% male, with a mean age of 31 years. The MESS ranged from 6 to 11, and the ISS ranged from 9 to 41. The main pathology of the injured vessels was contusion/thrombosis in 28 legs, which were repaired by interposition-reversed long saphenous vein graft. Seven patients developed postoperative thrombosis and underwent thrombectomy/embolectomy. Failure of limb salvage occurred in seven limbs with no mortality.

Conclusions:

Severe multi-segmental bone fractures, prolong ischemic time of >10 h, and MESS of ≥9 are significant predictors of limb loss in patients with blunt leg trauma in association with vascular injuries.

Wilderness Medical Society practice guidelines for the prevention and treatment of lightning injuries: 2014 update

To provide guidance to clinicians about best practices, the Wilderness Medical Society (WMS) convened an expert panel to develop evidence-based guidelines for the treatment and prevention of lightning injuries. These guidelines include a review of the epidemiology of lightning and recommendations for the prevention of lightning strikes, along with treatment recommendations organized by organ system. Recommendations are graded on the basis of the quality of supporting evidence according to criteria put forth by the American College of Chest Physicians. This is an updated version of the original WMS Practice Guidelines for Prevention and Treatment of Lightning Injuries published in Wilderness & Environmental Medicine 2012;23(3):260-269.

Educational and clinical impact of Advanced Trauma Life Support (ATLS) courses: a systematic review

BACKGROUND

We aimed to systematically review the literature on the educational impact of Advanced Trauma Life Support (ATLS) courses and their effects on death rates of multiple trauma patients.

METHODS

All Medline, Pubmed, and the Cochrane Library English articles on the educational impact of ATLS courses and their effects on trauma mortality for the period 1966-2012 were studied. All original articles written in English were included. Surveys, reviews, editorials/letters, and other trauma courses or models different from the ATLS course were excluded. Articles were critically evaluated regarding study research design, statistical analysis, outcome, and quality and level of evidence.

RESULTS

A total of 384 articles were found in the search. Of these, 104 relevant articles were read; 23 met the selection criteria and were critically analyzed. Ten original articles reported studies on the impact of ATLS on cognitive and clinical skills, six articles addressed the attrition of skills gained through ATLS training, and seven articles addressed the effects of ATLS on trauma mortality. There is level I evidence that ATLS significantly improves the knowledge of participants managing multiple trauma patients, their clinical skills, and their organization and priority approaches. There is level II-1 evidence that knowledge and skills gained through ATLS participation decline after 6 months, with a maximum decline after 2 years. Organization and priority skills, however, are kept for up to 8 years following ATLS. Strong evidence showing that ATLS training reduces morbidity and mortality in trauma patients is still lacking.

CONCLUSIONS

It is highly recommended that ATLS courses should be taught for all doctors who are involved in the management of multiple trauma patients. Future studies are required to properly evaluate the impact of ATLS training on trauma death rates and disability.

A multi-centred audit of secondary spinal assessments in a trauma setting: are we ATLS compliant?

PURPOSE

The global incidence of spinal cord injuries varies with the developed world having improved survival and 1 year mortality in a poly-trauma setting. This improved survival has been estimated at 20 % in a recent Cochrane review of Advanced Trauma Life Support (ATLS).The aim of this audit is to evaluate the management of patients with suspected spinal cord injury by the trauma and orthopaedic team in three centres in South Wales.

METHODS

A retrospective case note review of the secondary survey was performed. Inclusion criteria were patients 18 years and above, with poly-trauma and presenting to Accident and Emergency department at the treating hospital. We used ATLS guidelines as an audit tool and reviewed the documentation of key components of the secondary assessment.

RESULTS

Forty-nine patients were included (29 males, 20 females) with an average age of 53.7 years (19-92 years). We found that completion of all components of the secondary survey for spinal injury was poor, 29 % receiving a digital per rectal examination despite suspected spinal injury. Paralysis level was not documented in 20.4 % of patients. Medical Research Council grade was only documented in 24.5 % although was assessed in 73.5 %. The secondary survey took place after 2 h in 54.6 % of patients.

CONCLUSION

We found that the documentation of the performance of a secondary survey was poor. We found that most patients included in this study are not currently meeting the minimal standard suggested by the ATLS guidelines.

Evolution and development of the Advanced Trauma Life Support (ATLS) protocol: a historical perspective

The Advanced Trauma Life Support (ATLS) protocol is a successful course offered by the American College of Surgeons. Once based on didactic lectures and seminars taught by experts in the field, trauma training has evolved to become a set of standardized assessment and treatment protocols based on evidence rather than expert opinion. As the ATLS expands, indices to predict outcome, morbidity, and mortality have evolved to guide management and treatment based on retrospective data. This historical, perspective article attempts to tell the story of ATLS from its inception to its evolution as an international standard for the initial assessment and management of trauma patients.

Valor diagnóstico da tomografia de coluna cervical em vítimas de trauma contuso

OBJETIVO. Avaliar o valor da tomografia computadorizada no diagnóstico de lesões da coluna e medula cervicais em vítimas de trauma contuso. MÉTODOS. Revisão dos prontuários de vítimas de trauma contuso atendidas de janeiro de 2006 a dezembro de 2008. Foram analisados os seguintes dados: epidemiológicos, mecanismo de trauma, transporte das vítimas para o hospital, atendimento intra-hospitalar, critérios de indicação da TC, diagnóstico, tratamento, e evolução das vítimas em estudo. As vítimas foram distribuídas em dois grupos: Grupo I - sem lesão na coluna cervical; Grupo II - com lesão na coluna cervical . RESULTADOS. Foram analisados os prontuários de 3.101 vítimas. A tomografia computadorizada foi indicada em 1.572 (51%) pacientes, Foi observado predomínio masculino entre as vítimas (79%), com média etária de 38,53 anos no Grupo I e 37,60 anos no Grupo II. A distribuição dos mecanismos de trauma foi semelhante nos dois grupos. Lesões encontradas: 53 fraturas, oito listeses vertebrais e oito lesões medulares. As sequelas incluíram: três paraplegias, cinco tetraplegias e oito sequelas de lesão cerebral. No Grupo II ocorreram sete óbitos ,no Grupo I 240. A duração média de internação hospitalar foi de 11 dias para o Grupo I e 26,2 dias para o Grupo II. CONCLUSÃO. A TC de coluna cervical em vítimas de trauma contuso foi eficaz na identificação de lesões da coluna e medula cervicais. Assim, apesar do custo da TC cervical, e da baixa incidência de lesões por ela identificáveis, a sua indicação baseada nos critérios usuais parece justificável.

Increase in early mechanical ventilation of burn patients: an effect of current emergency trauma management?

BACKGROUND

Data relating to patients admitted with extensive burn injuries in the Netherlands have revealed a marked increase in patients whose initial care included mechanical ventilation (MV). The increase was abrupt, dating from 1997, and has been sustained since. The aim of this study is to quantify this observation and to discuss possible causes.

METHODS

The study included 258 consecutive patients with burns >30% total body surface area admitted to the Beverwijk burns center. Patients were divided into two groups based on admission date: group 1 from 1987 to 1996 (n=135) and group 2 from 1997 to 2006 (n=123). Data were analyzed using χ or analysis of variance.

RESULTS

There were no differences between groups in demographics, facial burns, inhalation injury, and % total body surface area. However, the number of patients subjected to MV at admission increased from 38% to 76% (group 1 vs. 2; p<0.001). In 57% of patients who were intubated based on the suspicion of inhalation injury, this condition could not be confirmed (p<0.05 vs. 9% [1987-1996]).

CONCLUSIONS

This study has confirmed that a higher proportion of patients were treated with MV since 1997, whereas the severity of burn injury remained unchanged throughout the study period. In the absence of a clinical explanation, we surmise that there has been a change within Dutch casualty departments in the initial management of major burn injury. The change coincides with the implementation of the Advanced Life Trauma Support training course as the accepted standard of trauma care in Dutch hospitals.

Fluid Therapy in Trauma

Advances in shock resuscitation have occurred as a result of various military conflicts. Primary objective of trauma care is to minimize or reverse shock, avoiding the lethal triad of hypothermia, acidosis, and coagulopathy. The concept of Damage Control Resuscitation has evolved along with "damage control surgery" which includes hypotensive and haemostatic resuscitation, where small aliquots of fluid are infused, with hypovolaemia and hypotension tolerated as a necessary evil until definitive haemorrhage control can be achieved. In the initial stages of trauma resuscitation the precise fluid, crystalloid or colloid, used is probably not important as long as an appropriate volume is given. Haemostatic resuscitation includes early use of fresh frozen plasma in a 1:1 ratio with packed red cells with emphasis on whole blood, frequent cryo precipitates and platelets and the use of recombinant Factor VII for control of bleeding.

Effects of the Emergency Trauma Training Course on the confidence of final-year medical students dealing with trauma patients

Trauma is an important issue that has been neglected in the training of medical students. This study evaluated the effects of the Emergency Trauma Training Course (ETTC), after completion of standard medical training, on seventh-year medical students. The ETTC was designed in Taiwan by the Taiwan Society of Emergency Medicine to train physicians and registered nurses who care for trauma patients in the emergency department (ED). We implemented the course for our medical students' internship. One hundred and fifty-one participants were divided into three groups: Group A included 36 medical students before they entered their internship in hospital; Group B included 41 medical students who had received 6 months of internship training in hospital; and Group C included 74 ED nurses. Group C was used to test Cronbach's alpha coefficient of the questionnaire. After the training course, the participants had a final examination and filled out a questionnaire about the training course and their levels of self-confidence. There were no differences in scores between the medical students in Groups A and B (p = 0.064). Using repeated measures analysis of variance, we found that confidence before training was low, with no difference between Groups A and B. Confidence improved after training, but there was still no significant difference between the groups (p = 0.875). However, there were significant differences between confidence levels before and after the training course (p < 0.001). Therefore, although inhospital training for 6 months failed to increase confidence, the confidence of final year medical students after completion of their training was improved by the ETTC. This indicates that the ETTC could increase the confidence of participants. This is the first evaluation of the implementation of the ETTC for final-year medical students in Taiwan. Based on our results, we highly recommend that this training course be taught to final-year medical students before they practice in hospital.

Evaluation of fundamental critical care course in Kenya: knowledge, attitude, and practice

BACKGROUND

Critical care training for medical personnel is crucial for the survival of the highest acuity patients. The Fundamental Critical Care Course (FCCS), a critical care course developed by the Society of Critical Care Medicine, permits course adaption and, thus, has potential for global dissemination. The FCCS course was provided in two Kenyan hospitals after minimal adaption. Participant knowledge and confidence gain as well as FCCS applicability to an African context were evaluated.

METHODS

Questionnaires and a multiple-choice test were administered to assess knowledge, attitude, and self-reported confidence or self-efficacy. For applicability, the pre-course questionnaire assessed participant expectations and existing levels of confidence/knowledge in the care of the critically ill patient. Post-course, the participant evaluated the overall quality of the course, lectures, and skill stations along with context applicability questions.

RESULTS

There were 100 participants, 45 doctors, 45 nurses, and 10 clinical officers. There was a 22.7% gain in the mean test score (P < 0.0001) after the course, with 98% of participants showing improvement. Confidence to perform new skills post-course, or self-efficacy, was demonstrated by a median of 4 or greater on a Likert scale of 5 (most confident) in 10 of 12 clinical scenarios and in 11 of 14 new procedures. There was a consistency between areas reported as needed expertise, and participant evaluation of similar lecture and skill station's quality and appropriateness. The most common areas reported were mechanical ventilation, patient monitoring, and their related procedures.

CONCLUSIONS

The FCCS course met participant's expectations and was reported as applicable for the Kenyan context with minimal adaption. Post-course, knowledge improved and confidence increased for implementation of new skills in clinical care situations. We confirmed the effectiveness and relevancy of the FCCS course for other resource-constrained health care settings.

Three decades (1978-2008) of Advanced Trauma Life Support (ATLS) practice revised and evidence revisited

The Advanced Trauma Life Support (ATLS) Program was developed to teach doctors one safe, reliable method to assess and initially manage the trauma patient. The ATLS principles represents an organized approach for evaluation and management of seriously injured patients and offers a foundation of common knowledge for all members of the trauma team. After 3 decades of teaching (1978-2008) of ATLS worldwide one should intuitively perceive that the evidence for the effect of ATLS teaching on the improved management of the injured patient be well established. This editorial addresses aspects of trauma education with needs for further development of better evidence of best practice.

Pro/con debate: is the scoop and run approach the best approach to trauma services organization?

You are asked to be involved in organizing a trauma service for a major urban center. You are asked to make a decision on whether the services general approach to trauma in the city (which does have a well-established trauma center) will be scoop and run (minimal resuscitation at the scene with a goal to getting the patient to a trauma center as quickly as possible) or on-the-scene resuscitation with transfer following some degree of stabilization.

Trauma surgery: discipline in crisis

Throughout the past quarter century, there have been slow but dramatic changes in the nature and practice of trauma surgery, and this field increasingly faces potent economic, logistic, political, and workforce challenges. Patients and emergency physicians have much to lose by this budding crisis in our partner discipline. This article reviews the specific issues confronting trauma surgery, their historical context, and the potential directions available to this discipline. Implications of these issues for emergency physicians and for trauma care overall are discussed.

Advanced Trauma Life Support® – ein Versorgungsstandard für Deutschland?

Over the last 30 years the Advanced Trauma Life Support (ATLS) course has become the most successful training program in the world for the early care of severely injured patients. It has shaped trauma care systems in many countries and is now on the verge of being introduced into Germany by the German Society of Trauma Surgery (DGU). However, after publication of the latest edition in 2004 there are rising concerns regarding the lack of multi-disciplinarity, out-dated contents and lack of adaptability to regional needs. This article questions the beneficial effect of ATLS on the advanced German trauma care system and concludes that ATLS is not likely to improve trauma care in Germany.

Teaching the trauma teachers: an international review of the Advanced Trauma Life Support Instructor Course

OBJECTIVES

To identify educational variations between Advanced Trauma Life Support (ATLS) Instructor Courses in the UK, USA and Australia, to determine the impact of any such variations, and to consider their contributory role in future course development.

METHODS

Observational, participatory qualitative study of ATLS Instructor Courses held in three representative teaching centres in 2006 and 2007.

RESULTS

Each international territory has developed individual approaches to the teaching of common course content. These approaches have a variable impact upon the educational efficacy of the course.

CONCLUSIONS

Observation of educational practice in international course centres allows for a richer understanding of the nature and extent of variations in teaching methods and course organisation. The amalgamation of these variations will facilitate a more inclusive international common platform for the 8th edition Instructor Course.

Trauma education and care in the jungle of Ecuador, where there is no advanced trauma life support

BACKGROUND

The advanced trauma life support course is not available or affordable to rural areas in low-income countries. A trauma continuing education course was created to educate physicians of rural hospitals in the jungles of Ecuador.

METHODS

A basic trauma care course was designed based on local resources and location of injury, including rudimentary health posts in the jungle, rural hospitals, and definitive referral centers. Course effectiveness was evaluated by a comparison of test scores before and after the course. A multiple choice questionnaire was given. Comparison to previous test scores was also performed. Paired Student's t test was used for statistical analysis. An objective structured clinical examination (OSCE), based on the course design, was administered.

RESULTS

Twenty-six rural physicians participated in the course. Mean test scores significantly improved from pretest to post-test (72% to 79%; p = 0.032). Knowledge deficiencies in prehospital care, extremity injury care, and patient evaluation adjuncts significantly improved from 23% to 87%, 23% to 100%, and 31% to 100%, respectively. Test results after the course showed improvements in all major categories tested. Twelve of the 26 participants were repeat test takers from a course provided 2 years earlier. These participants showed improved pretest scores compared with their highest previous test score (76.8% versus 68.5%; p = 0.0496). Compared with first-time test takers, these participants showed improved pretest (76.8% versus 68.4%) as well as post-test (81% versus 76%) scores. Twenty-five of the 26 physicians participated in the OSCE, with a pass rate of 76%. The OSCE identified various strengths and deficiencies based on patient location and available resources. In rudimentary health posts, management was adequate for hemorrhage control (65%), immobilization (77%), and early transfer to rural hospitals (92%). Prehospital communication was inadequate (53%). Rural hospital management was adequate for primary evaluation (60%) and resuscitation (74%) but poor in secondary patient evaluation (53%), adjuncts (25%), and transfer to definitive referral centers (11%). OSCE scores differed from multiple choice questionnaire test results.

DISCUSSION

Where there is no advanced trauma life support, a tailored trauma course and evaluation can be effective in educating local providers. A well-designed competency evaluation (multiple choice questionnaire and OSCE) is helpful in identifying deficient local aspects of trauma care. The course design and evaluation methods may serve as a model for continuing trauma care education in developing countries.

The culture of a trauma team in relation to human factors

AIM

The aim of this ethnographic study was to explore the culture of a trauma team in relation to human factors.

BACKGROUND

Traumatic injury is the leading cause of death in the first four decades of life in the western world. Evidence suggests that the initial assessment and resuscitation of trauma victims is most successfully carried out by an organized trauma team. Most trauma teams use Advanced Trauma Life Support principles which focus on rapid assessment and management of the patient's injuries. Similarly, most trauma education focuses on Advanced Trauma Life Support principles, concentrating firmly on the patient's physical status. Nevertheless, contemporary literature about emergency teams suggests that human factors, such as communication and interprofessional relationships, can affect the team's performance regardless of how clinically skilled the team members are.

METHOD

Focused ethnography was used to explore the culture of a trauma team in one teaching hospital. Six periods of observation were undertaken followed by 11 semi-structured interviews with purposively chosen key personnel. Data from transcripts of the observation field notes and interviews were analysed using open coding, followed by formation of categories resulting in the emergence of six central categories.

RESULTS

Findings suggest that leadership, role competence, conflict, communication, the environment and the status of the patient all influence the culture of the trauma team. Interpretation of these categories suggests that trauma team education should include human factor considerations such as leadership skills, team management, interprofessional teamwork, conflict resolution and communication strategies.

RELEVANCE FOR CLINICAL PRACTICE

The findings suggest that support systems for role development of junior team leaders should be formalized. The proven airline industry techniques of Crew Resource Management, focusing on teamwork and effective communication, could be implemented into continuing professional development for trauma teams to engender collaboration and interprofessional practice.

The initial assessment and management of the multiple-trauma patient with an associated spine injury

STUDY DESIGN

Review and summary of the relevant literature from multiple disciplines.

OBJECTIVE

Provide the readership with evidence-based guidelines on the initial assessment and treatment of the multiple-trauma patient with an associated spinal column injury.

SUMMARY OF BACKGROUND DATA

Early operative stabilization of the isolated spinal column injury has decreased hospital and intensive care unit length of stay. Early intervention has not provided consistently improved neurologic outcomes. The timing of spinal column stabilization in the multiple-trauma patient continues to be a source of discussion.

METHODS

Review of published English literature from 1990 to present using key words: spinal trauma, multiple-trauma with spinal injury; timing of spinal injury treatment; spinal fracture management; and Advanced Trauma Life Support.

CONCLUSIONS

The treatment of the poly-trauma patient with an associated spinal column injury requires strict adherence to Advanced Trauma Life Support principles. Once life and limb-threatening injuries have been identified and addressed, spinal column assessment and neurologic protection must be maintained at the highest priority. Early spinal stabilization can be performed safely in the multiple-trauma patient in medical centers, in which medical and ancillary staff is available on a 24-hour basis and is familiar with these procedures.
