Trauma patient outcome after the Prehospital Trauma Life Support program

The value of pre-hospital trauma life support courses for medical personnel-a questionnaire study

Background

The aim of the study was to determine the impact that PHTLS® course participation had on self-confidence of emergency personnel, regarding the pre-hospital treatment of patients who had suffered severe trauma. Furthermore, the goal was to determine the impact of specific medical profession, work experience and prior course participation had on the benefits of PHTLS® training.

Methods

A structured questionnaire study was performed. Healthcare providers from local emergency services involved in pre-hospital care in the metropolitan area of Zurich (Switzerland, Europe) who completed a PHTLS® course were included. Altered self-confidence, communication, and routines in the treatment of severe trauma patients were examined. The impact of prior course participation, work experience and profession on course benefits were evaluated.

Results

The response rate was 76%. A total of 6 transport paramedics (TPs), 66 emergency paramedics (EPs) and 15 emergency doctors (EDs) were included. Emergency paramedics had significantly more work experience compared with EDs (respectively 7.1 ± 5.7 yrs. vs. 4.5 ± 2.1 yrs., p = 0.004). 86% of the participants reported increased self-confidence in the pre-hospital management of severe trauma upon PHTLS® training completion. Moreover, according to 84% of respondents, extramural treatment of trauma changed upon course completion. PHTLS® course participants had improved communication in 93% of cases. This was significantly more frequent in EPs than TPs (p = 0.03). Multivariable analysis revealed emergency paramedics benefit the most from PHTLS® course participation.

Conclusion

The current study shows that PHTLS® training is associated with improved self-confidence and enhanced communication, with regards to treatment of severe trauma patients in a pre-hospital setting, among medical emergency personnel. Additionally, emergency paramedics who took the PHTLS® course improved in overall self-confidence. These findings imply that all medical personal involved in the pre-hospital care of trauma patients, in a metropolitan area in Europe, do benefit from PHTLS® training. This was independent of the profession, previous working experience or prior alternative course participation.

Worldwide snapshot of trauma team structure and training: an international survey

INTRODUCTION

Trauma teams (TTs) are a key tool in trauma care, as they bring a multidisciplinary approach to the trauma patient, improving outcomes. Excellent teamwork (TW) requires not only individual skills but also training at non-technical skills (NTS). Although there is evidence supporting TTs, there is little information regarding how they are organized and trained. With this study, we intend to assess the reality of TTs all over the world, focusing on how they are organized and trained.

MATERIALS AND METHODS

We composed a 42-question sheet on Google Forms, in four different languages (English, Polish, Portuguese, and Spanish). The questions regarded the respondents' background, and their respective hospitals' trauma patient management, TT features and its training, NTS and TW. The survey was shared on social media, through the International Assessment Group of Online Surgical & Trauma Education community, and the European Society of Trauma and Emergency Surgery. Statistical analysis was performed on Statistical Package for the Social Sciences (SPSS®) version 27.

RESULTS

We obtained 296 answers from 52 different countries, with 6 having at least 10 answers (Brazil, Portugal, Poland, Spain, Italy, and USA). While the majority of the respondents (97%) agreed that TTs can improve outcomes, only 61% have a TT in their hospital, with 69% of these being dedicated TTs. General surgery (76%), trauma surgery (68%), and anesthesia (66%) were the three most common specialties in the teams. Teams performed briefings and debriefings with a frequency of, at least, "often" in only 49% and 38%, respectively. Only 50% and 33% of the respondents stated that their hospital provided trauma management courses focusing on individual technical skills, and TT training courses, respectively. The Advanced Trauma Life Support (85%), the Definitive Surgical and Anesthetic Trauma Care (38%), and the European Trauma Course (31%) were the three trauma management courses of choice. Regarding TT training courses, the European Trauma Course (52%) and local/in-house (42%) courses were the most common ones. Most participants (93%) stated that NTS were highly important in trauma care. However, only 60% of the respondents had postgraduate training on NTS and TW, and only 24% had this type of training on an undergraduate level.

CONCLUSION

The number of TTs worldwide does not match their relevance in trauma care. Institutions are not providing enough trauma courses, particularly TT training courses and NTS teaching. Implementing TT should include promotion of team courses, as well as team briefings and debriefings.

Non-hospital healthcare center's preparedness assessment toolbar for providing basic emergency care: a sequential exploratory mixed-method study

BACKGROUND

Basic emergency management in urban and rural areas is a critical challenge, which can affect the pre-hospital mortality rate. Therefore, Non-hospital Healthcare Center (NHHC) must be prepared to manage such emergency cases that may occur in the geographic area where these centers act. The main aim of the study was to develop and validate an toolbar for NHHCs' preparedness to provide initial emergency care.

METHODS

This study was designed based on a sequential exploratory mixed- method in two phases, in each of which there are three steps. In the phase I, the literature systematic review and qualitative methods (Focus Group Discussions (FGDs) and Semi-Structured Interviews (SSIs)) were applied to identify the domains and items. In the phase II, content validity, feasibility, and reliability of the toolbar were performed. Content validity was assessed using a modified Kappa coefficient based on clarity and relevance criteria. Feasibility of the toolbar was randomly assessed through its implementation in 10 centers in Tabriz. Reliability was randomly assessed in a pilot on 30 centers. Reliability was assessed by measuring internal consistency, test-retest reliability, and inter-rater agreement. The main statistical methods for assessing reliability include Cronbach's alpha, Intra-class Correlation Coefficient, and Kendal's Tau-b. All the statistical analyses were performed using Stata 14.

RESULTS

In the phase I, primary version of the toolbar containing 134 items related to assessing the preparedness of NHHCs was generated. In the phase II, item reduction was applied and the final version of the toolbar was developed containing 126 items, respectively. These items were classified in 9 domains which include: "Environmental Infrastructures of Centers", "Protocols, Guidelines and Policies", "Medical Supplies and Equipment", "Emergency Medicines", "Human Resources", "Clinical Interventions", "Maintenance of equipment", "Medicine Storage Capability", and "Management Process". The toolbar had acceptable validity and reliability.

CONCLUSIONS

This study provided a standard and valid toolbar that can be used to assess the preparedness of NHHCs to deliver initial emergency care.

International comparison of injury care structures, processes, and outcomes between integrated trauma systems in Québec, Canada, and Victoria, Australia

BACKGROUND

Quality improvement activities in trauma systems are widely based on comparisons between trauma centers within the same system. Comparisons across different trauma systems may reveal further opportunities for quality improvement.

OBJECTIVES

This study aimed to compare the integrated trauma systems in Québec, Canada and in Victoria, Australia, regarding their structures, care processes and patient outcomes.

METHODOLOGY

The elements recommended by the American College of Surgeons were used to compare trauma systems structures. Comparisons of care processes and patient outcomes were based on data from major trauma admissions extracted from trauma registries (2013 and 2017). Care processes included time to reach a definitive care facility, time spent in the emergency department, and time lapsed before the first head computed tomography (CT) scan. These care processes were compared using a z-test of log-transformed times. Hospital mortality and hospital length of stay (LOS) were compared using indirect standardization based on multiple logistic and linear regression.

RESULTS

Major differences in trauma system structure were Advanced Trauma Life Support at the scene of injury (Victoria), the use of validated prehospital triage tools (Québec), and mandatory accreditation of all trauma centers (Québec). Patients in Québec arrived at their definitive care hospital earlier than their counterparts in Victoria (median: 1.93 vs. 2.13 h, p = 0.002), but spent longer in the emergency department (median: 8.23 vs. 5.15 h, p<0.0001) and waited longer before having their first head CT (median: 1.90 vs. 1.52 h, p<0.0001). In-hospital mortality and hospital LOS were higher in Québec than in Victoria (standardized mortality ratio: 1.15, 95% CI: 1.09 - 1.20; standardized LOS ratio: 1.10, 95% CI: 1.09 - 1.11).

CONCLUSION

We observed important differences in the structural components and care processes in Québec and Victoria's trauma systems, which might explain some of the observed differences in patient outcomes. This study shows the potential value of international comparisons in trauma care and identifies possible opportunities for quality improvement.

Pre-hospital trauma care in Switzerland and Germany: do they speak the same language?

PURPOSE

Swiss and German (pre-)hospital systems, distribution and organization of trauma centres differ from each other. It is unclear if outcome in trauma patients differs as well. Therefore, this study aims to determine differences in characteristics, therapy and outcome of trauma patients between both German-speaking countries.

METHODS

The TraumaRegister DGU® (TR-DGU) was used. Patients with Injury Severity Score ≥ 9 admitted to a level 1 trauma centre between 01/2009 and 12/2017 were included if they required ICU care or died. Trauma pattern, pre-hospital procedures and outcome were compared between Swiss (CH, n = 4768) and German (DE, n = 66,908) groups.

RESULTS

Swiss patients were older than German patients (53 vs. 50 years). ISS did not differ between groups (CH 23.8 vs. DE 23.0 points). There were more low falls < 3 m (34% vs. 21%) at the expense of less traffic accidents (37% vs. 52%) in the Swiss population. In Switzerland 30% of allocations were done without physician involvement, whereas this occurred in 4% of German cases. Despite a comparable number of patients with a GCS ≤ 8 (CH 29.6%; DE 26.4%), differences in pre-hospital intubation rates occurred (CH 31% vs. DE 40%). Severe traumatic brain injuries were diagnosed most frequently in Switzerland (CH 62% vs. DE 49%). Admission vital signs were similar, and standardized mortality ratios were close to one in both countries.

CONCLUSION

This study demonstrates that patients' age, trauma patterns and pre-hospital care differ between Germany and Switzerland. However, adjusted mortality was almost similar. Further benchmarking studies are indicated to optimize trauma care in both German-speaking countries.

Preparedness of non-hospital health centers to manage patients with life-threatening emergency conditions: findings from a qualitative study

BACKGROUND

Management of Life-threatening Emergency (LTE) patients in urban and rural areas is an important challenge, which can affect pre-hospital mortality rate. Therefore, Non-hospital Health Center (NHHC) must be prepared to manage such emergency cases that may occur in the geographic area where these centers act. The aim of this study was to explore domains related to the preparedness of NHHCs to manage LTE patients through resorting to healthcare providers' and experts' perspectives.

METHODS

A qualitative exploratory study was applied using Semi-Structured Interviews (SSIs) and Focus Group Discussions (FGDs). Prior to beginning data collection, the study and its objectives were explained to the participants and their informed consents were obtained. Then, SSIs and FGDs were conducted by two trained researchers using an interview guide, which was developed through literature review and consulting experts. In total, 12 SSIs were done with the providers at different NHHCs in Tabriz. In addition, 2 FGDs were conducted with the specialists in Emergency Medicine (EM) and Primary Health Care (PHC), and the executives of health centers, with over 5 years of work experience, and Emergency Medical Services (EMS) experts. Purposive sampling method was used in this study. All SSIs and FGDs were audio recorded and subsequently transcribed. Framework Analysis was employed to manually analyze the interview transcripts from all the SSIs and FGDs.

RESULTS

The interview transcripts analysis resulted in the emergence of 3 themes and 11 sub-themes, categorized according to Donabedian's triple model. 5 sub-themes were related to input, including medical equipment and supplies, environmental infrastructures of the centers, emergency medicines, human resource, and protocols, guidelines and policies. 4 sub-themes were related to process, including providing clinical services, medicine storage capacity, maintenance of equipment, and management process. Finally, 2 sub-themes were related to outcome, which were patients' satisfaction with the quality of care and improved survival of LTE patients.

CONCLUSIONS

The results of this study can provide a new perspective for health managers and policy makers on how to evaluate the preparedness of NHHCs in managing LTE patients. In addition, it will be used to develop instruments to measure the preparedness of these centers.

Terrorist attacks: common injuries and initial surgical management

Terrorism-related incidents and shootings that involve the use of war weapons and explosives are associated with gunshot and blast injuries. Despite the perceived threat of terrorism, these incidents and injuries are rare in Germany. For this reason, healthcare providers are unlikely to have a full understanding of the special aspects of managing these types of injuries. Until a clear and complete picture of the situation is available after a terrorist or shooter incident, tactical and strategic approaches to the clinical management of the injured must be tailored to circumstances that have the potential to overwhelm resources temporarily. Hospitals providing initial care must be aware that the first patients who are taken to medical facilities will present with uncontrollable bleeding from injuries to the trunk and body cavities. To improve the outcome of these patients in extremis, the aim of the index surgery is to stop the bleeding and control the contamination. Unlike damage control surgery, which is tailored to the patient's condition, tactical abbreviated surgical care (TASC) is first and foremost adapted to the overall situation. Once the patients are stabilised and all information on the situation is available, the surgical management and reconstruction of gunshot and blast injuries can follow the principles of damage control (DC) and definitive early total care (ETC). The purpose of this article is to provide an overview of the pathophysiology of gunshot and blast injuries, wound ballistics, and the approach and procedures of successful surgical management.

Needs assessment of emergency medical and rescue services in Abuja/Nigeria and environs

BACKGROUND

Nigeria is ranked second highest in the rate of road accidents and other emergencies (Deaths, disabilities) among 193 countries of the world. There is therefore the need for analyzing Emergency Medical Rescue Services (EMRS) in the country to identify options for improvement.

METHOD

The study was conducted from February, 2016 to March, 2017 in three EMRS organizations (FRSC, NEMA and MAITAMA Hospital) located in Abuja. The structure, resources, process of EMRS activities and outcome (delay times, case fatality as well as victims and service-providers satisfaction with services) were assessed through observation, time measurements and interviews.

RESULTS

FRSC and NEMA offers (Road Traffic Injury) RTI and Disaster services, the ambulances consist of Intensive Care Unit(ICU) buses, Helicopters, Speed boats, motorbikes and other specialized vehicles. Mortality and morbidity recorded for 2016 was 1.1 and 2% respectively. MAITAMA is a specialist centre that offers general medical services. A total number 1227(88.8%) lives were saved during the observational period by three organizations, 60(4.9%) deaths, 132 (9.6%) disabilities, 793 (57.2%) NCDs and 593(42.8%) RTI.

CONCLUSION

Non-communicable diseases (NCDs) cause many deaths and morbidities in the developing world compared to infectious diseases. There is need for total revamping and education of EMRS institutions in Nigeria and Low- Middle Income Countries (LMICs). Abuja and its surroundings suffers from delays in rapid emergency services, lack of adequate awareness, functional ambulances, minimal specialists and inadequate consumables lead to the loss of many lives.

[Preclinical and intrahospital management of mass casualties and terrorist incidents]

Due to the recent terrorist attacks in Paris, Brussels, Ansbach, Munich, Berlin and more recently Manchester and London, terrorism is realized as a present threat to our society and social life, as well as a challenge for the health care system. Without fueling anxiety, there is a need for sensitization to this subject and to familiarize all concerned with the special kind of terrorist attack-related injuries, the operational priorities and tactics and the individual basic principles of preclinical and hospital care. There is a need to adapt the known established medical structure for a conventional mass casualty situation to the special requirements that are raised by this new kind of terrorist threat to our social life. It is the aim of this article, from a surgical point of view, to depict the tactics and challenges of preclinical care of the special kind of terrorist attack-related injuries from the site of the incident, via the advanced medical post or casualty collecting point, to the triage point at the hospital. The special needs of medical care and organizational aspects of the primary treatment in the hospital are highlighted and possible decisional options and different approaches are discussed.

Lay First Responder Training in Eastern Uganda: Leveraging Transportation Infrastructure to Build an Effective Prehospital Emergency Care Training Program

BACKGROUND

Though road traffic injuries (RTIs) are a major cause of mortality in East Africa, few countries have emergency medical services. The aim was to create a sustainable and efficient prehospital lay first responder program, creating a system with lay first responders spread through the 53 motorcycle taxi stages of Iganga Municipality.

METHODS

One hundred and fifty-four motorcycle taxi riders were taught a first aid curriculum in partnership with a local Red Cross first aid trainer and provided with a first aid kit following WHO guidelines for basic first aid. Pre- and post-survey tests measured first aid knowledge improvement over the course. Post-implementation incident report forms were collected from lay first responders after each patient encounter over 6 months. Follow-up interviews were conducted with 110 of 154 trainees, 9 months post-training.

RESULTS

Improvement was measured across all five major first aid categories: bleeding control (56.9 vs. 79.7%), scene management (37.6 vs. 59.5%), airway and breathing (43.4 vs. 51.6%), recovery position (13.1 vs. 43.4%), and victim transport (88.2 vs. 94.3%). From the incident report findings, first responders treated 250 victims (82.8% RTI related) and encountered 24 deaths (9.6% of victims). Of the first aid skills, bleeding control and bandaging was used most often (55.2% of encounters). Lay first responders provided transport in 48.3% of encounters. Of 110 lay first responders surveyed, 70 of 76 who had used at least one skill felt "confident" in the care they provided.

CONCLUSION

A prehospital care system composed of lay first responders can be developed leveraging existing transport organizations, offering a scalable alternative for LMICs, demonstrating usefulness in practice and measurable educational improvements in trauma skills for non-clinical lay responders.

Impact of Trauma System Structure on Injury Outcomes: A Systematic Review and Meta-Analysis

BACKGROUND

The effectiveness of trauma systems in decreasing injury mortality and morbidity has been well demonstrated. However, little is known about which components contribute to their effectiveness. We aimed to systematically review the evidence of the impact of trauma system components on clinically important injury outcomes.

METHODS

We searched MEDLINE, EMBASE, Cochrane CENTRAL, and BIOSIS/Web of Knowledge, gray literature and trauma association Web sites to identify studies evaluating the association between at least one trauma system component and injury outcome. We calculated pooled effect estimates using inverse-variance random-effects models. We evaluated quality of evidence using GRADE criteria.

RESULTS

We screened 15,974 records, retaining 41 studies for qualitative synthesis and 19 for meta-analysis. Two recommended trauma system components were associated with reduced odds of mortality: inclusive design (odds ratio [OR] = 0.72 [0.65-0.80]) and helicopter transport (OR = 0.70 [0.55-0.88]). Pre-Hospital Advanced Trauma Life Support was associated with a significant reduction in hospital days (mean difference [MD] = 5.7 [4.4-7.0]) but a nonsignificant reduction in mortality (OR = 0.78 [0.44-1.39]). Population density of surgeons was associated with a nonsignificant decrease in mortality (MD = 0.58 [-0.22 to 1.39]). Trauma system maturity was associated with a significant reduction in mortality (OR = 0.76 [0.68-0.85]). Quality of evidence was low or very low for mortality and healthcare utilization.

CONCLUSIONS

This review offers low-quality evidence for the effectiveness of an inclusive design and trauma system maturity and very-low-quality evidence for helicopter transport in reducing injury mortality. Further research should evaluate other recommended components of trauma systems and non-fatal outcomes and explore the impact of system component interactions.

Global Health and Emergency Care: Defining Clinical Research Priorities

OBJECTIVES

Despite recent strides in the development of global emergency medicine (EM), the field continues to lag in applying a scientific approach to identifying critical knowledge gaps and advancing evidence-based solutions to clinical and public health problems seen in emergency departments (EDs) worldwide. Here, progress on the global EM research agenda created at the 2013 Academic Emergency Medicine Global Health and Emergency Care Consensus Conference is evaluated and critical areas for future development in emergency care research internationally are identified.

METHODS

A retrospective review of all studies compiled in the Global Emergency Medicine Literature Review (GEMLR) database from 2013 through 2015 was conducted. Articles were categorized and analyzed using descriptive quantitative measures and structured data matrices. The Global Emergency Medicine Think Tank Clinical Research Working Group at the Society for Academic Emergency Medicine 2016 Annual Meeting then further conceptualized and defined global EM research priorities utilizing consensus-based decision making.

RESULTS

Research trends in global EM research published between 2013 and 2015 show a predominance of observational studies relative to interventional or descriptive studies, with the majority of research conducted in the inpatient setting in comparison to the ED or prehospital setting. Studies on communicable diseases and injury were the most prevalent, with a relative dearth of research on chronic noncommunicable diseases. The Global Emergency Medicine Think Tank Clinical Research Working Group identified conceptual frameworks to define high-impact research priorities, including the traditional approach of using global burden of disease to define priorities and the impact of EM on individual clinical care and public health opportunities. EM research is also described through a population lens approach, including gender, pediatrics, and migrant and refugee health.

CONCLUSIONS

Despite recent strides in global EM research and a proliferation of scholarly output in the field, further work is required to advocate for and inform research priorities in global EM. The priorities outlined in this paper aim to guide future research in the field, with the goal of advancing the development of EM worldwide.

Outpatient Emergencies: Anaphylaxis

Anaphylactic fatalities are rare; however, mild reactions can rapidly progress to cardiovascular and respiratory arrest. The clinical course of anaphylaxis can be unpredictable. Prompt and early use of epinephrine should be considered. Most anaphylaxis episodes have an immunologic mechanism involving immunoglobulin E (IgE). Foods are the most common cause in children; medications and insect stings are more common in adults. When the cause is not completely avoidable or cannot be determined, a patient should be supplied with autoinjectable epinephrine and be instructed its use. They should keep the device with them at all times and taught the signs and symptoms of anaphylaxis.

Quality of Documentation as a Surrogate Marker for Awareness and Training Effectiveness of PHTLS-Courses. Part of the Prospective Longitudinal Mixed-Methods EPPTC-Trial

OBJECTIVE

Care for severely injured patients requires multidisciplinary teamwork. A decrease in the number of accident victims ultimately affects the routine and skills. PHTLS ("Pre-Hospital Trauma Life Support") courses are established two-day courses for medical and non-medical rescue service personnel, aimed at improving the pre-hospital care of trauma patients worldwide. The study aims the examination of the quality of documentation before and after PHTLS courses as a surrogate endpoint of training effectiveness and awareness.

METHODS

This was a prospective pre-post intervention trial and was part of the mixed-method longitudinal EPPTC (Effect of Paramedic Training on Pre-Hospital Trauma Care) study, evaluating subjective and objective changes among participants and real patient care, as a result of PHTLS courses. The courses provide an overview of the SAMPLE approach for interrogation of anamnestic information, which is believed to be responsible for patient safety as relevant, among others, "Allergies," "Medication," and "Patient History" (AMP). The focus of the course is not the documentation.

RESULTS

In total, 320 protocols were analyzed before and after the training. The PHTLS course led to a significant increase (p < 0.001) in the "AMP" information in the documentation. The subgroups analysis of "allergies" (+47.2%), "drugs" (+38.1%), and "medical history" (+27.8%) before and after the PHTLS course showed a significant increase in the information content.

CONCLUSION

In summary, we showed that PHTLS training improves documentation quality, which we used as a surrogate endpoint for learning effectiveness and awareness. In this regard, we demonstrated that participants use certain parts of training in real life, thereby suggesting that the learning methods of PHTLS training are effective. These results, however, do not indicate whether patient care has changed.

Evaluating trauma nursing education: An integrative literature review

OBJECTIVE

A review of the current literature evaluating trauma nursing education.

BACKGROUND

A variety of trauma nursing courses exist, to educate nurses working in trauma settings, and to maintain their continuing professional development. Despite an increase in the number of courses delivered, there appears to be a lack of evidence to demonstrate the effectiveness of trauma nursing education and in particular the justification for this resource allocation.

DESIGN

Integrative literature review.

DATA SOURCES

A search of international literature on trauma nursing education evaluation published in English from 1985 to 2015 was conducted through electronic databases CINAHL Plus, Google Scholar, PubMed, Austhealth, Science Citation Index Expanded (Web of Science), Sciverse Science Direct (Elsevier) & One file (Gale). Only peer reviewed journal articles identifying trauma course and trauma nursing course evaluation have been included in the selection criteria.

REVIEW METHODS

An integrative review of both quantitative and qualitative literature guided by Whittemore and Knafl's theoretical framework using Bowling's and Pearson's validated appraisal checklists, has been conducted for three months.

RESULTS

Only 17 studies met the inclusion criteria, including 14 on trauma course evaluation and 3 on trauma nursing course evaluation. Study findings are presented as two main themes: the historical evolution of trauma nursing education and evaluation of trauma nursing education outcomes.

CONCLUSION

Trauma nursing remains in its infancy and education in this specialty is mainly led by continuing professional development courses. The shortage of evaluation studies on trauma nursing courses reflects the similar status in continuing professional development course evaluation. A trauma nursing course evaluation study will address the gap in this under researched area.

Assessing Trauma Care Capabilities of the Health Centers in Northern Ghana

INTRODUCTION

Traffic-related injury is a major and increasing cause of global mortality, especially in low- and middle-income countries (LMICs). However, trauma systems, personnel, resources, and infrastructure are frequently insufficient to meet the needs of the population in this at-risk population in LMICs. In addition, these resources are not uniformly distributed, coordinated, nor well described within most countries. Trauma care resources have not previously been characterized in the Northern Region of Ghana.

METHODS

We performed uniform site evaluations and interviews at 92 hospitals in Northern Ghana. Trauma systems, material resources, and human resources were quantified. Equipment was characterized as available in the Emergency Department (ED), in the hospital only, or unavailable. Hospitals were categorized as primary, district, or referral.

RESULTS

Forty-two primary hospitals, 48 district hospitals, 3 regional hospitals, and 1 teaching hospital were surveyed. Over 95 % of hospitals reported having no training or systems for the care of injured patients. Substantial clinical equipment deficits were found at most primary hospitals. In over 90 % of these hospitals, the majority of circulation and monitoring, airway and breathing, and diagnostic imagining resources were not available. Equipment was also frequently unavailable at district and regional hospitals. When available, these resources were infrequently present in the ED.

CONCLUSIONS

Although resources may be unavoidably constrained, there are substantial opportunities to improve the systematic management of trauma care and improve the education of the medical providers regarding care of injured patients in the region studied.

Prehospital and Emergency Care: Updates from the Disease Control Priorities, Version 3

BACKGROUND

It is increasingly understood that emergency care systems can be cost-effective in low- and middle-income countries (LMICs). The development of such systems, however, is still a work in progress. This article updates previous work in providing the most recent estimates of the burden of disease sensitive to emergency care, the current state of knowledge on the feasibility of emergency care, effect on outcomes, and cost-effectiveness in LMICs, and future directions for research, policy, and implementation.

METHODS

We calculated the potential impact of prehospital and emergency care systems using updated and revised data based on the global burden of disease study. We then assessed the state of current knowledge and potential future directions for research and policy by conducting a review of the literature on current systems in LMICs.

RESULTS

According to these newest updates, 24 million deaths related to emergency medical conditions occur in LMICs annually, accounting for an estimated 932 million years of life lost. Evidence shows that multiple emergency care models can function in different local settings, depending on resources and urbanicity. Emergency care can significantly improve mortality rates from emergent conditions and be highly cost-effective. Further research is needed on implementation of emergency care systems as they become a necessary reality in developing nations worldwide.

CONCLUSIONS

Emergency care implementation in LMICs presents both challenges and opportunities. Investment in evidence-based emergency care, research on implementation, and system coordination in LMICs could lead to a more cost- and outcome-effective emergency care system than exists in advanced economies.

PHTLS ® (Prehospital Trauma Life Support) provider courses in Germany - who takes part and what do participants think about prehospital trauma care training?

Background

The goal of this study was to examine PHTLS Provider courses in Germany and to proof the assumption that formation of physicians and paramedics in prehospital trauma care can be optimized.

Methods

PHTLS participants were asked to fill out standardized questionnaires during their course preparation and directly after the course. There were some open questions regarding their professional background and closed questions concerning PHTLS itself. Further questions were to be answered on an analog scale in order to quantify subjective impressions of confidence, knowledge and also to describe individual levels of education and training.

Results

247 questionnaires could be analyzed. Physicians noted significant (p < 0.001) more deficits in their professional training than paramedics. 80% of the paramedics affirmed to have had adequate training with respect to prehospital trauma care, all physicians claimed not to have had sufficient training for prehospital trauma care situations at Medical School. Physicians were statistically most significant dissatisfied then paramedics (p < 0.001). While most participants gave positive feedback, anesthetists were less convinced of PHTLS (p = 0.005), didn’t benefit as much as the rest (p = 0.004) and stated more often, that the course was of less value for their daily work (p = 0.03). After the course confidence increased remarkably and reached higher rates than before the course (p < 0.001). After PHTLS both groups showed similar ratings concerning the course concept indicating that PHTLS could equalize some training deficits and help to gain confidence and assurance in prehospital trauma situations. 90% of the paramedics and 100% of the physicians would recommend PHTLS. Physicians and especially anesthetists revised their opinions with regard to providing PHTLS at Medical School after having taken part in a PHTLS course.

Conclusion

The evaluation of PHTLS courses in Germany indicates the necessity for special prehospital trauma care training. Paramedics and physicians criticize deficits in their professional training, which can be compensated by PHTLS. With respect to relevant items like confidence and knowledge PHTLS leads to a statistically significant increase in ratings on a visual analogue scale. PHTLS should be integrated into the curriculum at Medical School.

Trauma team

The introduction of trauma teams has improved patient outcome independently. The aim of establishing a trauma team is to ensure the early mobilization and involvement of more experienced medical staff and thereby to improve patient outcome. The team approach allows for distribution of the several tasks in assessment and resuscitation of the patient in a 'horizontal approach', which may lead to a reduction in time from injury to critical interventions and thus have a direct bearing on the patient's ultimate outcome. A trauma team leader or supervisor, who coordinates the resuscitation and ensures adherence to guidelines, should lead the trauma team. There is a major national and international variety in trauma team composition, however crucial are a surgeon, an Emergency Medicine physician or both and anaesthetist. Advanced Trauma Life Support training, simulation-based training, and video review have all improved patient outcome and trauma team performance. Developments in the radiology, such as the use of computed tomography scanning in the emergency room and the endovascular treatment of bleeding foci, have changed treatment algorithms in selected patients. These developments and new insights in shock management may have a future impact on patient management and trauma team composition.

Global health and emergency care: a postgraduate medical education consensus-based research agenda

Global emergency medicine (EM) is a rapidly growing field within EM, as evidenced by the increasing number of trainees and clinicians pursuing additional experiences in global health and emergency care. In particular, many trainees now desire opportunities at the postgraduate level by way of global EM fellowship programs. Despite this growing popularity, little is known of the effects of postgraduate training in global health and emergency care on learners and patients in the United States and abroad. During the 2013 Academic Emergency Medicine consensus conference on global health and emergency care, a group of leading educators at the postgraduate medical education level convened to generate a research agenda of pressing questions to be answered in this area. The consensus-based research agenda is presented in this article.

Emergency and trauma care in Pakistan: a cross-sectional study of healthcare levels

BACKGROUND

The importance of emergency medical care for the successful functioning of health systems has been increasingly recognised. This study aimed to evaluate emergency and trauma care facilities in four districts of the province of Sindh, Pakistan.

METHOD

We conducted a cross-sectional health facility survey in four districts of the province of Sindh in Pakistan using a modified version of WHO's Guidelines for essential trauma care. 93 public health facilities (81 primary care facilities, nine secondary care hospitals, three tertiary hospitals) and 12 large private hospitals were surveyed. Interviews of healthcare providers and visual inspections of essential equipment and supplies as per guidelines were performed. A total of 141 physicians providing various levels of care were tested for their knowledge of basic emergency care using a validated instrument.

RESULTS

Only 4 (44%) public secondary, 3 (25%) private secondary hospitals and all three tertiary care hospitals had designated emergency rooms. The majority of primary care health facilities had less than 60% of all essential equipments overall. Most of the secondary level public hospitals (78%) had less than 60% of essential equipments, and none had 80% or more. A fourth of private secondary care facilities and all tertiary care hospitals (n=3; 100%) had 80% or more essential equipments. The average percentage score on the physician knowledge test was 30%. None of the physicians scored above 60% correct responses.

CONCLUSIONS

The study findings demonstrated a gap in both essential equipment and provider knowledge necessary for effective emergency and trauma care.

A plea for Croatian trauma system

This paper provides an insight into Croatian health system with special focus on trauma care. The current situation is explained from a domestic point of view, but an independent review by foreign observers is also included. Fragmented approach to the treatment of injured patients in Croatia should be replaced by networking of health care componenets into a unique chain of help. The concept and five methodological steps in the development of a succesfull trauma system are presented. A good start is definitely a reorganization of existing knowledge on the basis of internationally licesed courses and the adoption of trauma registry as a standard for future discussion. Individual components of the trauma system can not be separately "optimized" so clinical and financial decisions should be planned exclusively on the integral level.

Improving Trauma Care in India: the Potential Role of the Rural Trauma Team Development Course (RTTDC)

The Rural Trauma Team Development Course (RTTDC) was devised to optimize trauma resuscitation training in under-resourced rural institutions. This program appears ideal for India because of its dense traffic, large population, and high frequency of rural trauma. We report on the feasibility and desirability of introducing RTTDC in India. An instructor course for 20 faculties and a provider course for 23 were conducted in New Delhi, India. The courses were evaluated by multiple choice question (MCQ) performance, by rating the modules on a three-point scale (1 = very relevant, 2 = relevant, and 3 = not relevant) for communication skills, principles of performance improvement and patient safety (PIPS), and clinical scenarios. Evaluation questionnaires including desirability of promulgation in India were completed using a five-point Likert Scale (1 = strongly agree, 2 = agree, 3 = neutral, 4 = disagree, and 5 = strongly disagree). Overall written comments were also provided. Both faculty and providers improved post-course MCQ scores (p < 0.05) with lower scores in the provider group. Seventy-eight percent faculty and 74 % providers rated the communication module very relevant. PIPS was rated very relevant by 72 % faculty and 65 % providers. There were over 150 comments, generally positive with over 90 % of both faculty and providers rating strongly agree to agree that the course be promulgated widely in India. The RTTDC including plans for promulgation was enthusiastically received in India, and its potential for improving trauma care including communication skills and PIPS appears excellent.

EMS response to an airliner crash

This report of an aircraft crash at a major airport in Kingston, Jamaica examines the response of the local Emergency Medical Services (EMS). Factors that impacted the response are discussed, and the need for more disaster simulation exercises is highlighted. The objective of this case report was to document the response of EMS personnel to the crash of American Airlines Flight 331, and to utilize the information to examine and improve the present protocol. While multiple errors can occur during a mass-casualty event, these can be reduced by frequent simulation exercises during which various personnel practice and learn designated roles. Efficient triage, proper communication, and knowledge of the roles are important in ensuring the best possible outcome. While the triage system and response of the EMS personnel were effective for this magnitude of catastrophe, more work is needed in order to meet predetermined standards. Ways in which this can be overcome include: (1) hosting more disaster simulation exercises; (2) encouraging more involvement with first responders; and (3) strengthening the links in the local EMS system. Vigorous public education must be instituted and maintained.

Trauma Incidents Attended by Emergency Medical Services in Victoria, Australia

Introduction:

International literature describing the profile of trauma patients attended by a statewide emergency medical services (EMS) system is lacking. Most literature is limited to descriptions of trauma responses for a single emergency medical service, or to patients transported to a specific Level-1 trauma hospital. There is no Victorian or Australian literature describing the type of trauma patients transported by a state emergency medical service.

Purpose:

The purpose of this study was to define a profile of all trauma incidents attended by statewide EMS.

Methods:

A retrospective cohort study of all patient care records (PCR) for trauma responses attended by Victorian Ambulance Services for 2002 was conducted. Criteria for trauma categories were defined previously, and data were extracted from the PCRs and entered into a secure data repository for descriptive analysis to determine the trauma profile. Ethics committee approval was obtained.

Results:

There were 53,039 trauma incidents attended by emergency ambulances during the 12-month period. Of these, 1,566 patients were in physiological distress, 11,086 had a significant pattern of injury, and a further 8,931 had an identifiable mechanism of injury. The profile includes minor trauma (n = 9,342), standing falls (n = 20,511), no patient transported (n = 3,687), and deceased patients (n = 459).

Conclusions:

This is a unique analysis of prehospital trauma. It provides a baseline dataset that may be utilized in future studies of prehospital trauma care. Additionally, this dataset identifies a ten-fold difference in major trauma between the prehospital and the hospital assessments.

Where There Are No Emergency Medical Services—Prehospital Care for the Injured in Mumbai, India

Introduction:

In a populous city like Mumbai, which lacks an organized pre-hospital emergency medical services (EMS) system, there exists an informal network through which victims arrive at the trauma center. This baseline study describes the prehospital care and transportation that currently is available in Mumbai.

Methods:

A prospective trauma database was created by interviewing 170 randomly selected patients from a total of 454 admitted over a two-month period (July–August 2005) at a Level-I, urban, trauma center.

Results:

The injured victim in Mumbai usually is rescued by a good Samaritan passer-by (43.5%) and contrary to popular belief, helped by the police (89.7%). Almost immediately after rescue, the victim begins transport to the hospital. No one waits for the EMS ambulance to arrive, as there is none. A taxi cab is the most popular substitute for the ambulance (39.3%). The trauma patient in India usually is a young man in his late-twenties, from a lower socioeconomic class. He mostly finds himself in a government hospital, as private hospitals are reluctant to provide trauma care to the seriously injured. The injured who do receive prehospital care receive inadequate and inappropriate care due to the high cost of consumables in resuscitation, and in part due to the providers' lack of training in emergency care. Those who were more likely to receive prehospital care suffered from road traffic injuries (odds ratio (OR) = 2.3) and those transported by government ambulances (OR = 10.83), as compared to railway accident victims (OR = 0 .41) and those who came by taxi (OR = 0.54).

Conclusions:

Currently, as a result of not having an EMS system, prehospital care is a citizen responsibility using societal networks. It is easy to eliminate this system and shift the responsibility to the state. The moot point is whether the state-funded EMS system will be robust enough in a resource-poor setting in which public hospitals are poorly funded. Considering the high funding cost of EMS systems in developed countries and the insufficient evidence that prehospital field interventions by the EMS actually have improved outcomes, Mumbai must proceed with caution when implementing advanced EMS systems into its congested urban traffic. Similar cities, such as Mexico City and Jakarta, have had limited success with implementing EMS systems. Perhaps reinforcing the existing network of informal providers of taxi drivers and police and with training, funding quick transport with taxes on roads and automobile fuels and regulating the private ambulance providers, could be more cost-effective in a culture in which sharing and helping others is not just desirable, but is necessary for overall economic survival.

Trauma care in Africa: a status report from Botswana, guided by the World Health Organization's "Guidelines for Essential Trauma Care"

BACKGROUND

Trauma represents a significant and increasing challenge to health care systems all over the world. This study aimed to evaluate the trauma care capabilities of Botswana, a middle-income African country, by applying the World Health Organization's Guidelines for Essential Trauma Care.

METHODS

All 27 government (16 primary, 9 district, 2 referral) hospitals were surveyed. A questionnaire and checklist, based on "Guidelines for Essential Trauma Care" and locally adapted, were developed as situation analysis tools. The questionnaire assessed local trauma organization, capacity, and the presence of quality improvement activity. The checklist assessed physical availability of equipment and timely availability of trauma-related skills. Information was collected by interviews with hospital administrators, key personnel within trauma care, and through on-site physical inspection.

RESULTS

Hospitals in Botswana are reasonably well supplied with human and physical resources for trauma care, although deficiencies were noted. At the primary and district levels, both capacity and equipment for airway/breathing management and vascular access was limited. Trauma administrative functions were largely absent at all levels. No hospital in Botswana had any plans for trauma education, separate from or incorporated into other improvement activities. Team organization was nonexistent, and training activities in the emergency room were limited.

CONCLUSIONS

This study draws a picture of trauma care capabilities of an entire African country. Despite good organizational structures, Botswana has room for substantial improvement. Administrative functions, training, and human and physical resources could be improved. By applying the guidelines, this study creates an objective foundation for improved trauma care in Botswana.

Training hospital providers in basic CPR skills in Botswana: acquisition, retention and impact of novel training techniques

OBJECTIVE

Globally, one third of deaths each year are from cardiovascular diseases, yet no strong evidence supports any specific method of CPR instruction in a resource-limited setting. We hypothesized that both existing and novel CPR training programs significantly impact skills of hospital-based healthcare providers (HCP) in Botswana.

METHODS

HCP were prospectively randomized to 3 training groups: instructor led, limited instructor with manikin feedback, or self-directed learning. Data was collected prior to training, immediately after and at 3 and 6 months. Excellent CPR was prospectively defined as having at least 4 of 5 characteristics: depth, rate, release, no flow fraction, and no excessive ventilation. GEE was performed to account for within subject correlation.

RESULTS

Of 214 HCP trained, 40% resuscitate ≥ 1/month, 28% had previous formal CPR training, and 65% required additional skills remediation to pass using AHA criteria. Excellent CPR skill acquisition was significant (infant: 32% vs. 71%, p<0.01; adult 28% vs. 48%, p<0.01). Infant CPR skill retention was significant at 3 (39% vs. 70%, p<0.01) and 6 months (38% vs. 67%, p<0.01), and adult CPR skills were retained to 3 months (34% vs. 51%, p=0.02). On multivariable analysis, low cognitive score and need for skill remediation, but not instruction method, impacted CPR skill performance.

CONCLUSIONS

HCP in resource-limited settings resuscitate frequently, with little CPR training. Using existing training, HCP acquire and retain skills, yet often require remediation. Novel techniques with increased student: instructor ratio and feedback manikins were not different compared to traditional instruction.

Prehospital Trauma Life Support (PHTLS) training of ambulance caregivers and impact on survival of trauma victims

BACKGROUND

The Prehospital Trauma Life Support (PHTLS) course has been widely implemented and approximately half a million prehospital caregivers in over 50 countries have taken this course. Still, the effect on injury outcome remains to be established. The objective of this study was to investigate the association between PHTLS training of ambulance crew members and the mortality in trauma patients.

METHODS

A population-based observational study of 2830 injured patients, who either died or were hospitalized for more than 24 h, was performed during gradual implementation of PHTLS in Uppsala County in Sweden between 1998 and 2004. Prehospital patient records were linked to hospital-discharge records, cause-of-death records, and information on PHTLS training and the educational level of ambulance crews. The main outcome measure was death, on scene or in hospital.

RESULTS

Adjusting for multiple potential confounders, PHTLS training appeared to be associated with a reduction in mortality, but the precision of this estimate was poor (odds ratio, 0.71; 95% confidence interval, 0.42-1.19). The mortality risk was 4.7% (36/763) without PHTLS training and 4.5% (94/2067) with PHTLS training. The predicted absolute risk reduction is estimated to correspond to 0.5 lives saved annually per 100,000 population with PHTLS fully implemented.

CONCLUSIONS

PHTLS training of ambulance crew members may be associated with reduced mortality in trauma patients, but the precision in this estimate was low due to the overall low mortality. While there may be a relative risk reduction, the predicted absolute risk reduction in this population was low.

The top five research priorities in physician-provided pre-hospital critical care: a consensus report from a European research collaboration

Background

Physician-manned emergency medical teams supplement other emergency medical services in some countries. These teams are often selectively deployed to patients who are considered likely to require critical care treatment in the pre-hospital phase. The evidence base for guidelines for pre-hospital triage and immediate medical care is often poor. We used a recognised consensus methodology to define key priority areas for research within the subfield of physician-provided pre-hospital critical care.

Methods

A European expert panel participated in a consensus process based upon a four-stage modified nominal group technique that included a consensus meeting.

Results

The expert panel concluded that the five most important areas for further research in the field of physician-based pre-hospital critical care were the following: Appropriate staffing and training in pre-hospital critical care and the effect on outcomes, advanced airway management in pre-hospital care, definition of time windows for key critical interventions which are indicated in the pre-hospital phase of care, the role of pre-hospital ultrasound and dispatch criteria for pre-hospital critical care services.

Conclusion

A modified nominal group technique was successfully used by a European expert group to reach consensus on the most important research priorities in physician-provided pre-hospital critical care.

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.

Promoting emergency medical care systems in the developing world: weighing the costs

Despite the global health community's historical focus on providing basic, cost-effective primary health care delivered at the community level, recent trends in the developing world show increasing demand for the implementation of emergency care infrastructures, such as prehospital care systems and emergency departments, as well as specialised training programmes. However, the question remains whether, in a setting of limited global health care resources, it is logical to divert these already-sparse resources into the development of emergency care frameworks. The existing literature overwhelmingly supports the idea that emergency care systems, both community-based and within medical institutions, improve important outcomes, including significant morbidity and mortality. Crucial to the success of any public health or policy intervention, emergency care systems also seem to be strongly desired at the community and governmental levels. Integrating emergency care into existing health care systems will ideally rely on modest, low-cost steps to augment current models of primary health care delivery, focusing on adapting the lessons learned in the developed world to the unique needs and local variability of the rest of the globe.

Barriers and facilitators to provide effective pre-hospital trauma care for road traffic injury victims in Iran: a grounded theory approach

Background

Road traffic injuries are a major global public health problem. Improvements in pre-hospital trauma care can help minimize mortality and morbidity from road traffic injuries (RTIs) worldwide, particularly in low- and middle-income countries (LMICs) with a high rate of RTIs such as Iran. The current study aimed to explore pre-hospital trauma care process for RTI victims in Iran and to identify potential areas for improvements based on the experience and perception of pre-hospital trauma care professionals.

Methods

A qualitative study design using a grounded theory approach was selected. The data, collected via in-depth interviews with 15 pre-hospital trauma care professionals, were analyzed using the constant comparative method.

Results

Seven categories emerged to describe the factors that hinder or facilitate an effective pre-hospital trauma care process: (1) administration and organization, (2) staff qualifications and competences, (3) availability and distribution of resources, (4) communication and transportation, (5) involved organizations, (6) laypeople and (7) infrastructure. The core category that emerged from the other categories was defined as "interaction and common understanding". Moreover, a conceptual model was developed based on the categories.

Conclusions

Improving the interaction within the current pre-hospital trauma care system and building a common understanding of the role of the Emergency Medical Services (EMS) emerged as key issues in the development of an effective pre-hospital trauma care process.

Resuscitation training in developing countries: a systematic review

OBJECTIVE

To evaluate whether the inclusion of any specific resuscitation training educational strategy in developing countries improves outcomes.

METHODS

As part of the International Liaison Committee on Resuscitation evidence evaluation process, a systematic review of the literature was conducted. The Cochrane database of systematic reviews; Medline; Google Scholar and EmBASE were searched using multiple search strategies.

RESULTS

Forty-four papers were relevant to review, including 38 studies that provided support for the use of resuscitation training programs in developing countries. All studies that examined self-efficacy (15 studies) and student satisfaction (8 studies) reported improvement. There was no consistent testing method for educational outcomes across studies and few studies examined both educational outcomes and patient outcome (1 of 15 self-efficacy, 0 of 18 cognitive knowledge, 0 of 8 psychomotor skills, 0 of 5 simulated operational performance). Fourteen of 15 studies that examined patient survival were either newborn or trauma resuscitation, 1 adult resuscitation, and none were in pediatric resuscitation. Increased patient survival after resuscitation training was variable, with an absolute risk reduction that ranged from 0% to 34%.

CONCLUSIONS

Resuscitation training in developing countries was well received and viewed as valuable training by the students and local counterparts. Important student, training environment characteristics, educational outcomes and patient outcomes were inconsistently defined and reported. Institution of training in trauma and newborn resuscitation in developing countries has significantly reduced mortality, but this has not been demonstrated with other training programs.

Current status of medical training in mountain rescue in America and Europe

Limited medical training of mountain rescuers may adversely affect the outcome of casualties. Thus, this study evaluated medical training of mountain rescuers in countries associated with the International Commission of Mountain Emergency Medicine. A questionnaire was completed by 33 mountain rescue services from 18 countries in America and Europe. First-aid topics taught most often are (absolute values, percentage): chest compression, hypothermia, cold injuries (32 of 33 organization 97%); avalanche rescue, first-aid kit of rescuer, cervical collar (31, 94%); hemorrhagic shock, automated blood pressure measurement, wound dressing (30, 91%); and heat injuries and SAM SPLINT (29, 88%). Cardiopulmonary resuscitation manikins are used in 32 (97%) organizations, and in 17 (52%) organizations manikins have feedback functionality. After training, exams are compulsory in 27 (83%) organizations. Yearly retraining is done in 12 (36%) organizations; 22 (67%) organizations would like to increase medical training. The study shows high variability in the medical training programs among the surveyed organizations and the need to improve medical education. The authors recommend standardization of medical training and examinations on an international level. Additional topics tailored to the typical injury and illness patterns of a particular area should supplement this core training. Training should be performed by highly qualified instructors on a yearly basis.

[Prehospital Trauma Life Support (PHTLS): An interdisciplinary training in preclinical trauma care]

INTRODUCTION

There is clinical evidence that standardized management of trauma patients in the emergency department improves outcome. Standardized prehospital management has been established for stroke patients and those suffering acute coronary syndrome. Prehospital treatment of trauma patients differs quite significantly from one system to another. The data from the German Trauma Registry show that the average time from accident until arrival in the emergency department is 72 min. This needs improvement.

RESULTS

PHTLS is a training course that teaches a systematic approach to the trauma patient in the preclinical setting. The aim is to rapidly and accurately assess the patient's physiologic status, treat according to priorities, and decide whether the patient is critical and needs rapid rescue and transport. Above all, it is important for caregivers to prevent secondary injury, to realize the relevance of timing in the initial treatment, and to assure a high standard of care. PHTLS provides the participant with knowledge, skills, and necessary behaviors. The course is open to persons in all specialties involved in the initial management of severely injured patients. The German Board of Emergency Technicians e.V. inaugurated the course concept in cooperation with the National Association of Emergency Medical Technicians (NAEMT) and the American College of Surgeons (ACS) and is authorized to organize PHTLS courses in Germany.

CONCLUSION

PHTLS teaches a standardized and established approach to the trauma patient in the emergency department. It has been established in 36 countries and the content is reviewed regularly to consider new scientific evidence. Healthcare personnel in Germany have the chance to participate in this international standard of care and to introduce their own experiences into the review process.

Evaluation of trauma care applying TRISS methodology in a Caribbean developing country

There have been conflicting reports regarding the applicability of Trauma Injury Severity Score (TRISS) methodology to evaluate trauma care in a developing country setting. The objective of this study was to apply TRISS methodology to evaluate trauma care in the public hospitals of a Caribbean developing country. A prospective, observational study was conducted in the three major general hospitals in Trinidad. Major trauma patients were included. Demographic data, waiting time in the Emergency Department, and nature of injury (blunt or penetrating) were noted. Revised Trauma Score, Injury Severity Score, and Glasgow Coma Scale were applied to all patients on admission. Hospital outcomes were noted. Predicted outcomes were calculated for adult patients using TRISS methodology. M, Z statistics and receiver operating characteristic (ROC) curve analysis were done. There were 326 trauma patients studied, of whom 279 adults were evaluated by the TRISS methodology. Men were more frequently involved in trauma than women; there was more blunt trauma than penetrating trauma. The M statistic was 0.98 and the overall Z statistic was 5.81. The ROC curve analysis showed TRISS to be a fair discriminator in the study case-mix with an area under the curve of 0.82 (95% confidence interval 0.69-0.96). There is a considerable disparity between predicted and observed outcomes when trauma patients are evaluated by the TRISS methodology in a developing country setting.

Effect of emergency medical technician certification for all prehospital personnel in a Latin American city

BACKGROUND

In Mexico and most other Latin American countries, many emergency medical services (EMS) systems rely on employees and volunteers with only on-the-job training and without formal Emergency Medical Technician (EMT) certification. This study sought to evaluate the costs and effectiveness of providing EMT certification to all personnel working in an EMS service in a Mexican city.

METHODS

At baseline, only 20% of the prehospital personnel (medics) working for the EMS service in Santa Catarina, Nuevo Leon, Mexico had EMT certification. During a 14-month period, all such medics obtained EMT certification. The process and outcome of trauma care were assessed before and after this training.

RESULTS

Mortality among persons treated by this EMS service decreased from 1.8% Before to 0.5% after the training. The injury severity, as reflected by the prehospital index (PHI), was different between the two periods. Hence, adjustment for PHI by logistic regression was performed. The PHI- adjusted odds ratio for death in the after period was 0.55 compared with the before period, representing a 45% reduction in risk of death after EMT training.

CONCLUSIONS

These data support the promotion of policies that require and enable EMT certification for all prehospital care providers in Mexico and potentially also in other Latin American and other middle-income developing countries.

Clinician vs mathematical statistical models: which is better at predicting an abnormal chest radiograph finding in injured patients?

OBJECTIVE

The purpose of this study was to determine if statistical models for prediction of chest injuries would outperform the clinician's (MD) ability to identify injured patients at risk for a thoracic injury diagnosed by chest radiograph (CXR).

DESIGN

A prospective observational study was done during a 12-month period.

SETTING

The study was conducted in a level I trauma center.

PATIENTS

Injured patients meeting trauma team activation criteria were enrolled to the study.

INTERVENTIONS

Physical examination findings by a clinician were interpreted and CXR was performed.

OUTCOME MEASURES

The accuracy of 2 mathematical models is compared against the accuracy of clinician's clinical judgment in predicting an injury by CXR. Two newly constructed multivariate models, binary logistic regression (LR) and classification and regression tree (CaRT) analysis, are compared to previously published data of clinician clinical assessment of probability of thoracic injury identified by CXR.

RESULTS

Data for 757 patients were analyzed. Classification and regression tree analysis developed a stepwise decision tree to determine which signs/symptoms were indicative of an abnormal CXR finding. The sensitivity (CaRT, 36.6%; LR, 36.3%; MD, 58.7%), specificity (CaRT, 98.3%; LR, 98.2%; MD, 96.4%), and error rates (CaRT, 0.93; LR, 0.94; MD, 0.82) show that the mathematical decision aids are less sensitive and risk more misclassification compared to clinician judgment in predicting an injury by CXR.

CONCLUSION

Clinician judgment was superior to mathematical decision aids for predicting an abnormal CXR finding in injured patients with chest trauma.
