Health and economic benefits of improved injury prevention and trauma care worldwide.

OBJECTIVES: Injury is a significant source of morbidity and mortality worldwide, and often disproportionately affects younger, more productive members of society. While many have made the case for improved injury prevention and trauma care, health system development in low- and middle-income countries is often limited by resources. This study aims to determine the economic benefit of improved injury prevention and trauma care in low- and middle-income countries. METHODS: This study uses existing data on injury mortality worldwide from the 2010 Global Burden of Disease Study to estimate the number of lives that could be saved if injury mortality rates in low- and middle-income countries could be reduced to rates in high-income countries. Using economic modeling--through the human capital approach and the value of a statistical life approach--the study then demonstrates the associated economic benefit of these lives saved. RESULTS: 88 percent of injury-related deaths occur in low- and middle-income countries. If injury mortality rates in low- and middle-income countries were reduced to rates in high-income countries, 2,117,500 lives could be saved per year. This would result in between 49 million and 52 million disability adjusted life years averted per year, with discounting and age weighting. Using the human capital approach, the associated economic benefit of reducing mortality rates ranges from $245 to $261 billion with discounting and age weighting. Using the value of a statistical life approach, the benefit is between 758 and 786 billion dollars per year. CONCLUSIONS: Reducing injury mortality in low- and middle-income countries could save over 2 million lives per year and provide significant economic benefit globally. Further investments in trauma care and injury prevention are needed.

An estimate of the number of lives that could be saved through improvements in trauma care globally.

BACKGROUND: Reducing the global burden of injury requires both injury prevention and improved trauma care. We sought to provide an estimate of the number of lives that could be saved by improvements in trauma care, especially in low income and middle income countries. METHODS: Prior data showed differences in case fatality rates for seriously injured persons (Injury Severity Score ≥ 9) in three separate locations: Seattle, WA (high income; case fatality 35%); Monterrey, Mexico (middle income; case fatality 55%); and Kumasi, Ghana (low income; case fatality 63%). For the present study, total numbers of injury deaths in all countries in different economic strata were obtained from the Global Burden of Disease study. The number of lives that could potentially be saved from improvements in trauma care globally was calculated as the difference in current number of deaths from trauma in low income and middle income countries minus the number of deaths that would have occurred if case fatality rates in these locations were decreased to the case fatality rate in high income countries. RESULTS: Between 1,730,000 and 1,965,000 lives could be saved in low income and middle income countries if case fatality rates among seriously injured persons could be reduced to those in high income countries. This amounts to 34-38% of all injury deaths. CONCLUSIONS: A significant number of lives could be saved by improvements in trauma care globally. This is another piece of evidence in support of investment in and greater attention to strengthening trauma care services globally.

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.

Emergency Medical Service (EMS) systems in developed and developing countries.

OBJECTIVES: To compare patient- and injury-related characteristics of trauma victims and pre-hospital trauma care systems among different developed and developing countries. METHOD: We collated de-identified patient-level data from national or local trauma registries in Australia, Austria, Canada, Greece, Germany, Iran, Mexico, New Zealand, the Netherlands, the United Kingdom and the United States. Patient and injury-related characteristics of trauma victims with injury severity score (ISS) >15 and the pre-hospital trauma care provided to these patients were compared among different countries. RESULTS: A total of 30,339 subjects from one or several regions in 11 countries were included in this analysis. Austria (51%), Germany (41%) and Australia (30%) reported the highest proportion of air ambulance use. Monterrey, Mexico (median 10.1min) and Montreal, Canada (median 16.1min) reported the shortest and Germany (median: 30min) and Austria (median: 26min) reported the longest scene time. Use of intravenous fluid therapy among advanced EMS systems without physicians as pre-hospital care providers, varied from 30% (in the Netherlands) to 55% (in the US). The corresponding percentages in advanced EMS systems with physicians actively involved in pre-hospital trauma care, excluding Montreal in Canada, ranged from 63% (in London, in the UK) to 75% in Germany and Austria. Austria and Germany also reported the highest percentage of pre-hospital intubation (61% and 56%, respectively). CONCLUSION: This study provides an early look at international variability in patient mix, process of care, and performance of different pre-hospital trauma care systems worldwide. International efforts should be devoted to developing a minimum standard data set for trauma patients.

Advancing injury prevention and trauma care in North America and globally.

Injury is a major global health problem. This article reviews ways in which the toll from injury can be lowered through the spectrum of injury control, including surveillance, prevention, and trauma care. There is room for improvement in the application of scientifically based, proved interventions at all points in the spectrum in all countries. The greatest attention is needed in low- and middle-income countries, however, where most of the world's people live, where injury rates are higher, and where few injury control activities have yet been undertaken.

Evaluation of Trauma Care capabilities in four countries using the WHO-IATSIC Guidelines for Essential Trauma Care.

BACKGROUND: We sought to identify affordable and sustainable methods to strengthen trauma care capabilities globally, especially in developing countries, using the Guidelines for Essential Trauma Care. These guidelines were created by the World Health Organization (WHO) and the International Society of Surgery and provide recommendations on elements of trauma care that should be in place at the range of health facilities globally. METHODS: The guidelines were used as a basis for needs assessments in 4 countries selected to represent the world's range of geographic and economic conditions: Mexico (middle income; Latin America); Vietnam (low income; east Asia); India (low income; south Asia); and Ghana (low income; Africa). One hundred sites were assessed, including rural clinics (n=51), small hospitals (n=34), and large hospitals (n=15). Site visits utilized direct inspection and interviews with administrative and clinical staff. RESULTS: Resources were partly adequate or adequate at most large hospitals, but there were gaps that could be improved, especially in low-income settings, such as shortages of airway equipment, chest tubes, and trauma-related medications; and prolonged periods where critical equipment (e.g., X-ray, laboratory) were unavailable while awaiting repairs. Rural clinics everywhere had difficulties with basic supplies for resuscitation even though some received significant trauma volumes. In all settings, there was a dearth of administrative functions to assure quality trauma care, including trauma registries, trauma-related quality improvement programs, and regular in-service training. CONCLUSIONS: This study identified several low-cost ways in which to strengthen trauma care globally. It also has demonstrated the usefulness of the Guidelines for Essential Trauma Care in providing an internationally applicable, standardized template by which to assess trauma care capabilities.

Evaluating trauma care capabilities in Mexico with the World Health Organization's Guidelines for Essential Trauma Care publication.

OBJECTIVE: To identify affordable, sustainable methods to strengthen trauma care capabilities in Mexico, using the standards in the Guidelines for Essential Trauma Care, a publication that was developed by the World Health Organization and the International Society of Surgery to provide recommendations on elements of trauma care that should be in place in the various levels of health facilities in all countries. METHODS: The Guidelines publication was used as a basis for needs assessments conducted in 2003 and 2004 in three Mexican states. The states were selected to represent the range of geographic and economic conditions in the country: Oaxaca (south, lower economic status), Puebla (center, middle economic status), and Nuevo León (north, higher economic status). The sixteen facilities that were assessed included rural clinics, small hospitals, and large hospitals. Site visits incorporated direct inspection of physical resources as well as interviews with key administrative and clinical staff. RESULTS: Human and physical resources for trauma care were adequate in the hospitals, especially the larger ones. The survey did identify some deficiencies, such as shortages of stiff suction tips, pulse oximetry equipment, and some trauma-related medications. All of the clinics had difficulties with basic supplies for resuscitation, even though some received substantial numbers of trauma patients. In all levels of facilities there was room for improvement in administrative functions to assure quality trauma care, including trauma registries, trauma-related quality improvement programs, and uniform in-service training. CONCLUSIONS: This study identified several low-cost ways to strengthen trauma care in Mexico. The study also highlighted the usefulness of the recommended norms in the Guidelines for Essential Trauma Care publication in providing a standardized template by which to assess trauma care capabilities in nations worldwide.

Evaluating trauma care capabilities in Mexico with the World Health Organization's Guidelines for Essential Trauma Care publication

OBJETIVO: Identificar formas asequibles y sustentables de reforzar los recursos para la atención de heridos en México aplicando las pautas contenidas en Guidelines for Essential Trauma Care [Pautas para el tratamiento básico de los heridos], publicación de la Organización Mundial de la Salud y de la Sociedad Quirúrgica Internacional que contiene recomendaciones sobre los componentes de la atención de heridos que deben poseer los servicios de salud de distintos niveles en todos los países. MÉTODOS: Las pautas publicadas (Guidelines) sirvieron de base para llevar a cabo evaluaciones de las necesidades en tres estados mexicanos en 2003 y en 2004. Los estados se escogieron con la idea de que estuviese representada la amplia variedad de condiciones geográficas y económicas del país: Oaxaca (en el sur y de estrato económico inferior), Puebla (en el centro y con un estrato económico mediano) y Nuevo León (en el norte y con un estrato económico más alto). Se evaluaron dieciséis centros entre los cuales había puestos de salud rurales, hospitales pequeños y hospitales grandes. Se hicieron visitas a todos los centros para llevar a cabo la inspección directa de los recursos físicos en cada uno y entrevistar a miembros clave del personal administrativo y clínico. RESULTADOS: Los recursos humanos y físicos destinados a la atención de heridos eran de calidad satisfactoria en los hospitales, especialmente los más grandes. La encuesta reveló algunas deficiencias, tales como una escasez de succionadores rígidos, oxímetros de pulso y algunos medicamentos usados para tratar heridos. En todos los puestos se observaron dificultades con los equipos básicos de reanimación, a pesar de que algunos recibían un número bastante alto de heridos. En los centros de todos los niveles había margen para mejorar las funciones administrativas a fin de conseguir una atención de calidad que incluyese el mantenimiento de registros de heridos, programas para mejorar la atención de estos pacientes y uniformidad en el adiestramiento del personal durante el desempeño de sus funciones. CONCLUSIONES: En este estudio se identificaron varias formas baratas de reforzar la atención de pacientes heridos en México. También se subrayó la utilidad de las pautas recomendadas en la obra Guidelines for Essential Trauma Care como modelo estandarizado para evaluar los recursos para el tratamiento de heridos que poseen los países en cualquier parte del mundo.

Strengthening trauma and critical care globally.

PURPOSE OF REVIEW: Trauma is an increasingly significant health problem globally, especially in low-income and middle-income countries. Trauma care is often compromised by economic restrictions. Many capable individuals are attempting to meet this challenge in their own countries, however. This review summarizes such efforts and assesses how they might be expanded in a comprehensive, global fashion. RECENT FINDINGS: Options for improving trauma care in the prehospital setting have been explored, including strengthening existing, basic formal emergency medical services (including ambulances); instituting new formal emergency medical services, where none had previously existed; and exploring novel ways to strengthen existing, although informal, systems of prehospital care when formal emergency medical services would be unfeasible. Affordable ways by which to strengthen hospital care have been addressed for several specific injuries, including open fractures, burns, and vascular injuries. Especially notable are growing efforts to better monitor outcomes and address factors contributing to preventable deaths. The Essential Trauma Care Project has defined and promoted core essential trauma care services that every injured person in the world realistically can and should be able to receive. This project is a collaborative effort of the World Health Organization and the International Society of Surgery. SUMMARY: Individual efforts must be built upon to make progress in a comprehensive, global fashion. This review summarizes the background, achievements, and future potential of the Essential Trauma Care Project and several related efforts.

Human resources for the control of road traffic injury.

The definition of the ideal numbers and distribution of human resources required for control of road traffic injury (RTI) is not as advanced as for other health problems. We can nonetheless identify functions that need to be addressed across the spectrum of injury control: surveillance; road safety (including infrastructure, vehicle design, and behaviour); and trauma care. Many low-cost strategies to improve these functions in low- or middle-income countries can be identified. For all these strategies, there is need for adequate institutional capacity, including funding, legal authority, and human resources. Several categories of human resources need to be developed: epidemiologists who can handle injury data, design surveillance systems, and undertake research; engineers and planners versed in safety aspects of road design, traffic flow, urban planning, and vehicle design; police and lawyers who understand the health impact of traffic law; clinicians who can develop cost-effective improvements in the entire system of trauma treatment; media experts to undertake effective behaviour change and social marketing; and economists to assist with cost-effectiveness evaluations. RTI control can be strengthened by enhancing such training in these disciplines, as well as encouraging retention of those who have the needed skills. Mechanisms to enhance collaboration between these different fields need to be promoted. Finally, the burden of RTI is borne disproportionately by the poor; in addition to technical issues, more profound equity issues must be addressed. This mandates that people from all professional backgrounds who work for RTI control should develop skills in advocacy and politics.

Strengthening the prevention and care of injuries worldwide.

The global burden of injuries is enormous, but has often been overlooked in attempts to improve health. We review measures that would strengthen existing efforts to prevent and treat injuries worldwide. Scientifically-based efforts to understand risk factors for the occurrence of injury are needed and they must be translated into prevention programmes that are well designed and assessed. Areas for potential intervention include environmental modification, improved engineering features of motor vehicle and other products, and promotion of safe behaviours through social marketing, legislation, and law enforcement. Treatment efforts need to better define the most high-yield services and to promote these in the form of essential health services. To achieve these changes, there is a need to strengthen the capacity of national institutions to do research on injury control; to design and implement countermeasures that address injury risk factors and deficiencies in injury treatment; and to assess the effectiveness of such countermeasures. Although much work remains to be done in high-income countries, even greater attention is needed in less-developed countries, where injury rates are higher, few injury control activities have been undertaken, and where most of the world's population lives. In almost all areas, injury rates are especially high in the most vulnerable sections of the community, including those of low socioeconomic status. Injury control activities should, therefore, be undertaken in a context of attention to human rights and other broad social issues.

Cost-effectiveness and benefit of alternatives to improve training for prehospital trauma care in Mexico.

INTRODUCTION: In Latin America, there is a preponderance of prehospital trauma deaths. However, scarce resources mandate that any improvements in prehospital medical care must be cost-effective. This study sought to evaluate the cost-effectiveness of several approaches to improving training for personnel in three ambulance services in Mexico. METHODS: In Monterrey, training was augmented with PreHospital Trauma Life Support (PHTLS) at a cost of [US] dollar 150 per medic trained. In San Pedro, training was augmented with Basic Trauma Life Support (BTLS), Advanced Cardiac Life Support (ACLS), and a locally designed airway management course, at a cost of dollar 400 per medic. Process and outcome of trauma care were assessed before and after the training of these medics and at a control site. RESULTS: The training was effective for both intervention services, with increases in basic airway maneuvers for patients in respiratory distress in Monterrey (16% before versus 39% after) and San Pedro (14% versus 64%). The role of endotrachal intubation for patients with respiratory distress increased only in San Pedro (5% versus 46%), in which the most intensive Advanced Life Support (ALS) training had been provided. However, mortality decreased only in Monterrey, where it had been the highest (8.2% before versus 4.7% after) and where the simplest and lowest cost interventions were implemented. There was no change in process or outcome in the control site. CONCLUSIONS: This study highlights the importance of assuring uniform, basic training for all prehospital providers. This is a more cost-effective approach than is higher-cost ALS training for improving prehospital trauma care in environments such as Latin America.

Injury prevention counselling to improve safety practices by parents in Mexico.

OBJECTIVES: To evaluate the effectiveness of educational counselling programmes aimed at increasing parents' practice of childhood safety in Monterrey, Mexico, and to provide information aimed at helping to improve the effectiveness of future efforts in this field. METHODS: Three different counselling programmes were designed to meet the needs of the upper, middle and lower socioeconomic strata. Evaluation involved the use of baseline questionnaires on parents' existing safety-related practices for intervention and control groups and the administration of corresponding questionnaires after the programmes had been carried out. FINDINGS: Data were obtained on 1124 children before counselling took place and on 625 after it had been given. Overall safety scores (% safe responses) increased from 54% and 65% for the lower and upper socioeconomic strata, respectively, before counselling to 62% and 73% after counselling (P <0.001 for all groups). Improvements occurred both for activities that required caution and for activities that required the use of safety-related devices (e.g. helmets, car seats). However, scores for the use of such devices remained suboptimal even after counselling and there were wide discrepancies between the socioeconomic strata. The post-counselling scores for the use of safety-related devices were 55%, 38% and 19% for the upper, middle and lower socioeconomic strata, respectively. CONCLUSIONS: Brief educational interventions targeting parents' practice of childhood safety improved safe behaviours. Increased attention should be given to specific safety-related devices and to the safety of pedestrians. Educational efforts should be combined with other strategies for injury prevention, such as the use of legislation and the improvement of environmental conditions.

Strengthening care for injured persons in less developed countries: a case study of Ghana and Mexico.

In all countries, the priority for reducing road traffic injuries should be prevention. Nonetheless, there are low-cost ways to strengthen the care of injured persons, that will help to lower the toll from road traffic. The purpose of this review was to elucidate ways to accomplish this goal in the context of less developed countries. Studies selected for this review were obtained by Medline review, selecting on key words such as trauma, injury, trauma care, essential health services, and developing country. Articles pertaining to any country and all available years were considered. In addition, the authors utilized articles from the gray literature and journals from Mexico and Ghana that are not Medline referenced. Studies surveyed point to road safety and other forms of injury prevention, as well as prehospital care, as likely priorities for developing countries. Nonetheless, hospital-based improvements can contribute to decreases in mortality and, especially, decreases in disability. For both prehospital and hospital based care, studies revealed several critical weak points to address in: (1) human resources (staffing and training); (2) physical resources (equipment, supplies, and infrastructure); and (3) administration and organization. The 'essential services' approach, which has contributed to progress in a variety of fields of international health, needs to be developed for the care of the injured. This would define the trauma treatment services that could realistically be made available to virtually every injured person. It would then address the inputs of human resources, physical resources, and administration necessary to assure these services optimally in the different geographic and socioeconomic environments worldwide. Finally, it would identify and target deficiencies in these inputs that need to be strengthened.

Pedestrian traffic injuries in Mexico: a country update.

Road traffic injuries in general and pedestrian injuries in particular are a major public health problem in Mexico, especially in large urban areas. Analysis of mortality and road crashes at the national level was done using routine data recorded on death certificates. Fatality rates for different age groups were estimated by region for the year 2000. These data were supplemented by a cross-sectional study of pedestrian injuries in Mexico City based on death certificates information for pedestrians who lived and died in Mexico City between 1994 and 1997. Participant observation of physical spaces where crashes occurred was carried out. The spaces were filmed and in-depth interviews of survivors conducted. Road traffic crashes were responsible for approximately 17,500 deaths in Mexico during 2000. The mean age of the victims was 37 years. Mexico lost an average of 30 years of productive life for each individual who died in a traffic crash--525,000 years in 2000. An estimated 9500 (54.3%) of all fatalities were pedestrians, and for every pedestrian death there were 13 others who sustained nonfatal injuries requiring medical care. The overall crude mortality rate for pedestrian injuries in Mexico City was 7.14 per 100,000 (CI 6.85-7.42). A concentration of deaths was observed in 10 neighborhoods at specific types of street environments. The underlying factors included dangerous crossings and the absence or inadequacy of pedestrian bridges, as well as negative perceptions of road safety by pedestrians. In conclusion, this study demonstrates the importance of elucidating the underlying contextual determinants of pedestrian injuries.
