ABSTRACT
PURPOSE: This study aimed to estimate the health, economic, and environmental impacts of moderate simulated interventions on dietary intake in Brazil. METHODS: Data on food price and consumption were obtained from three nationwide surveys. Baseline dietary intake was estimated for 33,859 individuals aged 25 years and older. Counterfactual intakes were based on six hypothetical intervention scenarios, by changing the weekly frequency and serving size in low or high consumers of fruit and vegetables (FV), milk, whole grains, red and processed meats, and sugar-sweetened beverages. For each scenario, we estimated the attributable number of deaths and disability-adjusted life years (DALY), monetary cost, environmental impacts (14 midpoint indicators), and environmentally-mediated health impacts. RESULTS: Compared with the baseline intake and cost, the most expensive intervention (+ 8.3%) was to increase FV intake (+ 125 g), resulting in a 1.2% reduction in all-cause mortality (16,307 deaths/year). The cheapest (- 9.9%) was to reduce red and processed meat intake (- 40 g), resulting in a 1.1% reduction in all-cause mortality (14,272 deaths/year). The combined intervention was, on average, 3.7% cheaper than the baseline cost, resulting in an increase in diet cost for 30% of the population (45-22% in the lower- and higher-income groups); all-cause mortality would be reduced by 3.8% (49,488 deaths/year). Interventions targeting red and processed meats would reduce emissions and resource use by 35-55%, in addition to reducing 2300 DALYs/year. CONCLUSION: A meaningful number of deaths can be avoided and environmental impacts reduced through moderate and potentially affordable diet modifications.

While some studies have previously estimated lives saved by COVID-19 vaccination, we estimate how many deaths could have been averted by vaccination in the US but were not because of a failure to vaccinate. We used a simple method based on a nationally representative dataset to estimate the preventable deaths among unvaccinated individuals in the US from May 30, 2021 to September 3, 2022 adjusted for the effects of age and time. We estimated that at least 232,000 deaths could have been prevented among unvaccinated adults during the 15 months had they been vaccinated with at least a primary series. While uncertainties exist regarding the exact number of preventable deaths and more granular data are needed on other factors causing differences in death rates between the vaccinated and unvaccinated groups to inform these estimates, this method is a rapid assessment on vaccine-preventable deaths due to SARS-CoV-2 that has crucial public health implications. The same rapid method can be used for future public health emergencies.

Injury is both a national and international epidemic that affects people of all age, race, religion, and socioeconomic class. Injury was the fourth leading cause of death in the United States (U.S.) in 2021 and results in an incalculable emotional and financial burden on our society. Despite this, when prevention fails, trauma centers allow communities to prepare to care for the traumatically injured patient. Using lessons learned from the military, trauma care has grown more sophisticated in the last 50 years. In 1966, the first civilian trauma center was established, bringing management of injury into the new age. Now, the American College of Surgeons recognizes 4 levels of trauma centers (I-IV), with select states recognizing Level V trauma centers. The introduction of trauma centers in the U.S. has been proven to reduce morbidity and mortality for the injured patient. However, despite the proven benefits of trauma centers, the U.S. lacks a single, unified, trauma system and instead operates within a "system of systems" creating vast disparities in the level of care that can be received, especially in rural and economically disadvantaged areas. In this review we present the history of trauma system development in the U.S, define the different levels of trauma centers, present evidence that trauma systems and trauma centers improve outcomes, outline the current state of trauma system development in the U.S, and briefly mention some of the current challenges and opportunities in trauma system development in the U.S. today.
ABSTRACT
BACKGROUND: Ending preventable deaths of newborns and children under five by 2030 is among the United Nations Sustainable Development Goals. This study aimed to describe infant mortality rate due to preventable causes in Rio Grande do Sul (RS), the Southernmost state in Brazil. With 11,329,605 inhabitants and 141,568 live births in 2017, RS was the fifth most populous state in the country. METHOD: An ecological and cross-sectional statewide study, with data extracted from records of the Mortality Information System, Death Certificates, and Live Birth Certificates for the year 2017. Preventability was estimated by applying the List of Causes of Deaths Preventable through Intervention of SUS (acronym for Sistema Unico de Saude - Brazilian Unified Health System) Intervention. Rates of preventable infant mortality (PIMR), preventable early neonatal mortality (PENMR), preventable late neonatal mortality (PLNMR), and preventable post-neonatal mortality (PPNMR) per 1000 live births (LB) were quantified. Incidence ratios, according to contextual characteristics (human development index of the health region and of the municipality; Gini index of the municipality), maternal characteristics at the time of delivery (age, education, self-reported skin color, presence of a partner, number of antenatal care consultations, and type of delivery), and characteristics of the child at the time of birth (gestational age, weight, and pregnancy type) were calculated. RESULTS: In 2017, there were 141,568 live births and 1425 deaths of infants younger than 1 year old, of which 1119 were preventable (PIMR = 7.9:1000 LB). The PENMR, PLNMR, and PPNMR were 4.1:1000 LB; 1.5:1000 LB; and 2.3:1000 LB, respectively. More than 60% of deaths in the first week and 57.5% in the late neonatal period could be reduced through adequate care of the woman during pregnancy. The most frequent preventable neonatal causes were related to prematurity, mainly acute respiratory syndrome, and non-specified bacterial septicemia. In the post-neonatal period, 31.8% of deaths could be prevented through adequate diagnostic and treatment. CONCLUSIONS: The strategies needed to reduce preventable infant deaths should preferably focus on preventing prematurity, through adequate care of the woman during pregnancy.

BACKGROUND: An essential aspect of preventing further COVID-19 outbreaks and to learn for future pandemics is the evaluation of different political strategies, which aim at reducing transmission of and mortality due to COVID-19. One important aspect in this context is the comparison of attributable mortality. METHODS: We give a comprehensive overview of six epidemiological measures that are used to quantify COVID-19 attributable mortality (p-score, standardized mortality ratio, absolute number of excess deaths, per capita rate, z-score and the population attributable fraction). RESULTS: By defining the six measures based on observed and expected deaths, we explain their relationship. Moreover, three publicly available data examples serve to illustrate the interpretational strengths and weaknesses of the various measures. Finally, we give recommendation which measures are suitable for an evaluation of public health strategies against COVID-19. The R code to reproduce the results is available as online supplementary material. CONCLUSION: The number of excess deaths should be always reported together with the population attributable fraction, the p-score or the standardized mortality ratio instead of a per capita rate. For a complete picture of COVID-19 attributable mortality, quantifying and communicating its relative burden also to a lay audience is of major importance.

BACKGROUND: The National Academies of Science, Engineering, and Medicine defined a roadmap to achieve zero preventable trauma deaths. In the United States, there are over 5000 motorcycle fatalities annually. Florida leads the nation in annual motorcycle crash (MCC) deaths and injuries. It is unknown how many are potentially preventable. We hypothesize that certain patterns of injuries in on-scene fatalities that are potentially survivable and aim to make recommendations to achieve the National Academies of Science, Engineering, and Medicine objective. MATERIALS AND METHODS: Miami-Dade County medical examiner reports of MCC deaths pronounced on scene, and emergency medical service or law enforcement reports from 2010 to 2012 were reviewed by board-certified trauma surgeons. Causes of death were categorized into exsanguination, traumatic brain injury or decapitation, crushed chest, or airway complications. Determination of potentially survivable versus nonsurvivable injuries was based upon whether the riders had potentially survivable injuries and had they been transported immediately to a trauma center. Traumatic brain injury cases were reviewed by a board-certified neurosurgeon. RESULTS: Sixty MCC scene deaths were analyzed. Ninety-five percent were men, 55% were helmeted, and 42% had positive toxicology. The median Injury Severity Score was 41 (Range 14-75, IQR 31-75). Nineteen (32%) deaths were potentially survivable, with death due to airway in 14 (23%) and exsanguination in 4 (7%) patients. CONCLUSIONS: One-third of on-scene urban motorcycle deaths are potentially survivable in a young patient population. ISS score comparison demonstrates the lower injury burden in those deemed potentially survivable. Automatic alert systems in motorcycles and first responder training to police are recommended to improve trauma system efficacy in reducing preventable deaths from MCCs.

Morbidity and mortality conferences (MMCs) have three potential aims-to improve patient safety by reducing adverse events and preventable deaths, to improve overall quality of care as part of the hospital governance structure and as educational learning events. At present, medical MMCs vary widely in format and attendance from hospital to hospital. The evidence for MMCs actually reducing adverse events and preventing avoidable deaths is disappointing. There is better evidence for their educational role. The majority of medical deaths in hospitals are frail older people with poor life expectancy in whom inadequate care is more likely to be due to errors of omission rather than commission. Medical MMCs should be multidisciplinary and led by a senior clinician to encourage discussion and reflection in a 'blame-free' environment. They should be learning events for both clinicians and the organisation as a whole with a structure to support this.

INTRODUCTION: The aim is comparing the quality of care at a typical American trauma center (USC) vs. an equivalent European referral center in Spain (SRC), through the analysis of preventable and potentially preventable deaths. METHODS: Comparative study that evaluated trauma patients older than 16 years old who died during their hospitalization. We cross-referenced these deaths and extracted all deaths that were classified as potentially preventable or preventable. All errors identified were then classified using the JC taxonomy. RESULTS: The rate of preventable and potentially preventable mortality was 7.7% and 13.8% in the USC and SRC respectively. According to the JC taxonomy, the main error type was clinical in both centers, due to errors in intervention (treatment). Errors occurred mostly in the emergency department and were caused by physicians. In the USC, 73% of errors were therapeutic as compared to 59% in the SRC (P=.06). The SRC had a 41% of diagnosis errors vs just 18% in the USC (P = .001). In both centers, the main cause of error was human. At the USC, the most frequent human cause was 'knowledge-based' (44%). In contrast, at the SRC center the most common errors were 'rule-based' (58%) (P<.001). CONCLUSIONS: The use of a common language of errors among centers is key in establishing benchmarking standards. Comparing the quality of care of an American trauma center and a Spanish referral center, we have detected remarkably similar avoidable errors. More diagnostic and 'ruled-based' errors have been found in the Spanish center.

OBJECTIVE: The goal of this study was to inform public health policy which can reduce Colombia's estimated infant mortality rate (IMR), 17.78 deaths for 1000 live births (2011), by lowering preventable first day mortality (PFDM). STUDY DESIGN: This study combined a time series analysis, using a linear regression method, for the period 2001-2012 with a cross-sectional analysis, using odds ratios and bi-variate methods, for the year 2012 to study first day mortality (FDM) and PFDM classified by biological, socio-economic, and medical correlates. METHODS: The study examined the trends for 2001-2012 in Colombia's infant mortality rate per 1000, and in the relative significance of PFDM by cause. It established the relative odds of PFDM for 2012 by major risk categories, defined by birthweight and gestational age, and within those by biological, sociodemographic risk factors or groups and by potential access to and use of care. Then, the study established the major causes of PFDM within major risk categories and groups. RESULTS: Between 2001 and 2012, the average annual rate of FDM declined by 6.30%, while overall infant mortality only declined by 4.20%. Yet, in 2012, 37.04% of FDM was preventable by using proper pregnancy control (7.00% of total preventable), proper care during childbirth (37.20%), and handling causes associated with late diagnosis and treatment (55.80%). PFDM is primarily a socio-economic phenomenon, even among normal weight and gestational age newborns, who account for 32.73% of PFDM due to improper management of pregnancy and delivery among lower socio-economic and outlying populations, specifically in rural areas and among members of the inferior subsidised social insurance regime. CONCLUSION: From efficacy and probable cost effectiveness perspectives, intervention priority should be given to handling babies with normal gestation age and birthweight, and then to babies with very low gestation age and birthweight. At the same time, more prenatal visits could lead to fewer very high-risk situations at the outset. In view of the Colombian regulation to the contrary, the use of foetal monitoring and echography methods by all general practitioners should be considered. They should be trained accordingly. Policies should focus on members of the underprovided subsidised health insurance regime, rural areas, young, low-educated and single mothers during pregnancy, mainly delivery.

Oxygen is an essential medication used across all levels of healthcare for conditions such as surgery, trauma, heart failure, asthma, pneumonia, and maternal and child care. Despite its critical importance and inclusion on the World Health Organization's list of essential medicines, many low- and middle-income countries (LMICs) face significant challenges in providing adequate oxygen supplies. These challenges are exacerbated by the COVID-19 pandemic, which has drastically increased global oxygen demand. This paper examines the current challenges and advancements in the oxygen supply chain within LMICs, focusing on availability, infrastructure, and usage. It highlights the innovative solutions being implemented to improve oxygen access and offers strategic recommendations for enhancing oxygen delivery and maintenance in resource-limited settings.

BACKGROUND: Malaria is a leading cause of childhood mortality worldwide. However, accurate estimates of malaria prevalence and causality among patients who die at the country level are lacking due to the limited specificity of diagnostic tools used to attribute etiologies. Accurate estimates are crucial for prioritizing interventions and resources aimed at reducing malaria-related mortality. METHODS: Seven Child Health and Mortality Prevention Surveillance (CHAMPS) Network sites collected comprehensive data on stillbirths and children <5 years, using minimally invasive tissue sampling (MITS). A DeCoDe (Determination of Cause of Death) panel employed standardized protocols for assigning underlying, intermediate, and immediate causes of death, integrating sociodemographic, clinical, laboratory (including extensive microbiology, histopathology, and malaria testing), and verbal autopsy data. Analyses were conducted to ascertain the strength of evidence for cause of death (CoD), describe factors associated with malaria-related deaths, estimate malaria-specific mortality, and assess the proportion of preventable deaths. FINDINGS: Between December 3, 2016, and December 31, 2022, 2673 deaths underwent MITS and had a CoD attributed from four CHAMPS sites with at least 1 malaria-attributed death. No malaria-attributable deaths were documented among 891 stillbirths or 924 neonatal deaths, therefore this analysis concentrates on the remaining 858 deaths among children aged 1-59 months. Malaria was in the causal chain for 42.9% (126/294) of deaths from Sierra Leone, 31.4% (96/306) in Kenya, 18.2% (36/198) in Mozambique, 6.7% (4/60) in Mali, and 0.3% (1/292) in South Africa. Compared to non-malaria related deaths, malaria-related deaths skewed towards older infants and children (p < 0.001), with 71.0% among ages 12-59 months. Malaria was the sole infecting pathogen in 184 (70.2%) of malaria-attributed deaths, whereas bacterial and viral co-infections were identified in the causal pathway in 24·0% and 12.2% of cases, respectively. Malnutrition was found at a similar level in the causal pathway of both malaria (26.7%) and non-malaria (30.7%, p = 0.256) deaths. Less than two-thirds (164/262; 62.6%) of malaria deaths had received antimalarials prior to death. Nearly all (98·9%) malaria-related deaths were deemed preventable. INTERPRETATION: Malaria remains a significant cause of childhood mortality in the CHAMPS malaria-endemic sites. The high bacterial co-infection prevalence among malaria deaths underscores the potential benefits of antibiotics for severe malaria patients. Compared to non-malaria deaths, many of malaria-attributed deaths are preventable through accessible malaria control measures.

OBJECTIVE: To compare the burden and causes of maternal deaths between Syrian and Lebanese women for the period of 2010-2018. METHODS: A retrospective analysis was conducted of maternal deaths from the national notification system at the Ministry of Public Health in Lebanon during the period of 2010-2018. Maternal deaths among Syrian refugees and Lebanese citizens were compared based on cause of death, age of the woman, and nationality. Causes of maternal deaths were categorized as direct and indirect following WHO definitions. RESULTS: The maternal mortality ratio among the Syrian refugee women in Lebanon was higher than that of Lebanese women in the period 2010-2018, with its highest rate of 55.1 in 2017. Hemorrhage and indirect causes of maternal deaths are more common among Syrian refugee women whereas embolism and hypertension have higher proportions among Lebanese women. Maternal deaths within 48 h after birth are more common among Syrian than Lebanese women. CONCLUSION: Syrian refugee women carry an increased risk for maternal mortality in Lebanon. Improving timely access and equitable provision of appropriate care should be a priority for the health system in Lebanon.

BACKGROUND: Patient safety indicators (PSIs) are avoidable complications that can impact outcomes. Geriatric patients have a higher mortality than younger patients with similar injuries, and understanding the etiology may help reduce mortality. We aim to estimate preventable geriatric trauma mortality in the United States and identify PSIs associated with increased preventable mortality. METHODS: A retrospective cohort study of patients aged ≥65 years, in the CMS database, 2017-second quarter of 2020. Risk-adjusted multivariable regression was performed to calculate observed-to-expected (O/E) mortality ratios for failure-to-prevent and failure-to-rescue PSIs with significance defined as P < .05. RESULTS: 3 452 339 geriatric patients were analyzed. Patients aged 75-84 years had 33% higher odds of preventable mortality (adjusted odds ratio [aOR] = 1.33 and 95% confidence interval [CI] = 1.31, 1.36), whereas patients aged ≥85 years had 91% higher odds of preventable mortality (aOR = 1.91 and 95% CI = 1.87, 1.94) compared to patients aged 65-74 years. Failure-to-prevent O/E were >1 for all PSIs evaluated with central line-related blood stream infection having a high O/E (747.93). Failure-to-rescue O/E were >1 for 10/11 (91%) PSIs with physiologic and metabolic derangements having the highest O/E (5.98). United States' states with higher quantities of geriatric trauma patients experienced reduced preventable mortality. CONCLUSION: Odds of preventable mortality increases with age. Perioperative venous thrombotic events, hemorrhage or hematoma, and postoperative physiologic/metabolic derangements produce significant preventable mortalities. United States' states differ in their failure-to-prevent and failure-to-rescue PSIs. Utilization of national guidelines, minimization of central venous catheter use, addressing polypharmacy especially anticoagulation, ensuring operative and procedure-based competencies, and greater incorporation of inpatient geriatricians may serve to reduce preventable mortality in elderly trauma patients.

Road traffic collisions (RTC) are a major cause of mortality and morbidity in Botswana. To our knowledge no research has been conducted in Botswana to investigate preventable deaths that occur as a result of RTCs. The aim of this study is to establish the rate of preventable deaths from RTCs in the greater Gaborone area in Botswana. This was a 5-year retrospective study conducted at the forensic pathology department for the greater Gaborone area, in Botswana. Nine hundred and nine (909) forensic pathology reports were retrieved. Sixty-eight percent (68.2%) of RTC deaths were considered preventable. Head injury in isolation and in combination with other injuries accounted for 87.6% (796/909) of deaths. Haemorrhagic shock was present in 70.2% (638) of all documented injuries. Another documented injury contributing to fatal RTCs was high spinal cord injury. This injury was documented in 13.1% (119/909) of all deaths. We recommend the implementation of a comprehensive trauma system in Botswana to reduce the number of deaths from RTCs.

INTRODUCTION: Preventable deaths following trauma are high and unchanged over the last two decades. The objective of this study was to describe the location of death in patients with penetrating trauma, stratified by anatomic location of injury, in order to better tailor our approach to reducing preventable deaths from trauma. METHODS: This retrospective analysis of a prospectively maintained trauma registry included consecutive adult trauma activations with penetrating trauma at a level 1 trauma center between 07/2012 and 03/2018. Injuries were categorized as extremity, junctional, and torso. Head and neck injuries were excluded. Patients injured in >1 defined location were categorized as "multiple." Location of death was defined as on-scene, emergency department (ED), or hospital. Two-sided χ2 tests were used to compare groups. Multivariate analysis was performed using logistic regression. RESULTS: A total of 1024 patients were included with an overall case fatality rate (CFR) of 7.8%. The CFR following extremity injury (3.0%) was significantly lower than all other injury sites (P = .02).There were no significant differences in CFR for junctional (10.4%), torso (8.3%), or multiple injuries (9.6%). Forty percent of fatalities following junctional injury occurred on-scene and an additional 20% occurred in the ED. DISCUSSION: To our knowledge, this is the first study to describe location of death stratified by anatomic location of injury. There was no difference in the CFRs of junctional and torso injuries, and a large proportion of deaths occurred prior to reaching the hospital or in the trauma bay. These findings support reevaluating the classical algorithms and care pathways for patients with proximal penetrating trauma.

Noncompressible torso hemorrhage accounts for a significant portion of preventable trauma deaths. We report here on the development of injectable, targeted supramolecular nanotherapeutics based on peptide amphiphile (PA) molecules that are designed to target tissue factor (TF) and, therefore, selectively localize to sites of injury to slow hemorrhage. Eight TF-targeting sequences were identified, synthesized into PA molecules, coassembled with nontargeted backbone PA at various weight percentages, and characterized via circular dichroism spectroscopy, transmission electron microscopy, and X-ray scattering. Following intravenous injection in a rat liver hemorrhage model, two of these PA nanofiber coassemblies exhibited the most specific localization to the site of injury compared to controls (p < 0.05), as quantified using immunofluorescence imaging of injured liver and uninjured organs. To determine if the nanofibers were targeting TF in vivo, a mouse saphenous vein laser injury model was performed and showed that TF-targeted nanofibers colocalized with fibrin, demonstrating increased levels of nanofiber at TF-rich sites. Thromboelastograms obtained using samples of heparinized rat whole blood containing TF demonstrated that no clots were formed in the absence of TF-targeted nanofibers. Lastly, both PA nanofiber coassemblies decreased blood loss in comparison to sham and backbone nanofiber controls by 35-59% (p < 0.05). These data demonstrate an optimal TF-targeted nanofiber that localizes selectively to sites of injury and TF exposure, and, interestingly, reduces blood loss. This research represents a promising initial phase in the development of a TF-targeted injectable therapeutic to reduce preventable deaths from hemorrhage.

There is considerable evidence pointing to the existence of a socioeconomic gradient in mortality, which tends to be steeper in urban areas. Similar to other European cities, Lisbon is far from homogeneous since considerable geographical inequalities exist between the more advantaged and the more deprived neighborhoods. The main goals of this study are to describe the geographical pattern of premature deaths (before 65 years old), avoidable deaths (preventable and amenable to healthcare) and cause-specific mortality (HIV/AIDS and suicide) in Lisbon, at the lower administrative level (civil parish, in Portuguese: Freguesia), and analyze the statistical association between mortality risk and deprivation, before (1999-2003) and during the economic crisis (2008-2012). Smoothed Standardized Mortality Ratios (sSMR) and Relative Risk (RR) with 95% credible intervals were calculated to identify the association between mortality and deprivation. The analysis of the geographical distribution of cause-specific mortality reveals that civil parishes with high sSMR in the first period continued to present higher mortality rates in the second. Moreover, a significant statistical association was found between all the causes of death and deprivation, except suicide. These findings contribute to understanding how social conditions influence health outcomes and can offer insights about potential policy directions for local government.

BACKGROUND: Most studies of trauma deaths include non-preventable deaths, potentially limiting successful intervention efforts. In this study we aimed to compare the potentially preventable trauma deaths between 2 time periods at our institution. METHODS: Trauma patients who died in our hospital in 2005-2006 or 2012-2013 were included, non-preventable deaths were excluded from analysis. The Mann-Whitney and chi square test were used to compare variables between both time periods. RESULTS: 80% of deaths were non-preventable. Between the study time periods there was a decrease in potentially preventable deaths, from 29% to 12%, pâ¯<â¯0.001. Head injury deaths significantly decreased (40.6%-24.6%, pâ¯=â¯0.03), while hemorrhage deaths were stable during both time periods (47.6%-43.1%, pâ¯=â¯0.55). CONCLUSION: Potentially preventable trauma deaths decreased during the study period. Hemorrhage remains constant as the leading cause of potentially preventable deaths. Continued research to improve survival from hemorrhage is warranted.

SETTING: Mendi Provincial Hospital, Southern Highlands Province, Papua New Guinea (PNG). BACKGROUND: PNG is a high burden country for tuberculosis (TB) and TB-human immunodeficiency virus (HIV). TB is the second most common cause of death in PNG. OBJECTIVE: To identify the number of adult inpatients with TB who died between 1 January 2015 and 30 August 2017; describe these patients' characteristics and identify contributing factors that could be modified. DESIGN: This was a retrospective case series review. RESULTS: Among 905 inpatients with TB during the study period, there were 90 deaths. The patients who died were older than those who survived (median age 40 years vs. 32 years, P = 0.011). The majority of patients who died lived less than 3 hours from the hospital (71%), were diagnosed after admission (79%) and were clinically diagnosed (77%). HIV status was not known in 50% of the deaths. Of patients with a known status, 27% (12/45) were HIV-positive. The median symptom duration prior to presentation was 28 days, with females presenting later than males (84 vs. 28 days, P = 0.008). CONCLUSION: This study highlights areas where community and hospital-based management of TB could be improved to potentially reduce TB mortality, including earlier detection and treatment, improved bacteriological diagnosis and increased HIV testing.
ABSTRACT
BACKGROUND: Analyzing mortality in a mature trauma system is useful to improve quality of care of severe trauma patients. Standardization of error reporting can be done using the classification of the Joint Commission on the Accreditation of Healthcare Organizations (JCAHO). The aim of our study was to describe preventable deaths in our trauma system and to classify errors according to the JCAHO taxonomy. METHODS: We performed a six-year retrospective study using the registry of the Northern French Alps trauma network (TRENAU). Consecutive patients who died in the prehospital field or within their stay at hospital were included. An adjudication committee analyzed deaths to identify preventable or potentially preventable deaths from 2009 to 2014. All errors were classified using the JCAHO taxonomy. RESULTS: Within the study period, 503 deaths were reported among 7484 consecutive severe trauma patients (overall mortality equal to 6.7%). Seventy-two (14%) deaths were judged as potentially preventable and 36 (7%) deaths as preventable. Using the JACHO taxonomy, 170 errors were reported. These errors were detected both in the prehospital setting and in the hospital phase. Most were related to clinical performance of physicians and consisted of rule-based or knowledge based failures. Prevention or mitigation of errors required an improvement of communication among caregivers. CONCLUSIONS: Standardization of error reporting is the first step to improve the efficiency of trauma systems. Preventable deaths are frequently related to clinical performance in the early phase of trauma management. Universal strategies are necessary to prevent or mitigate these errors.
