Increasing trauma deaths in the United States.

Abstract: OBJECTIVE:: To determine the impact of the increasing aging population on trauma mortality relative to mortality from cancer and heart disease in the United States. BACKGROUND:: The population in the United States continues to increase as medical advancements allow people to live longer. The resulting changes in the leading causes of death have not yet been recognized. METHODS:: Data were obtained (2000-2010) from the Web-based Injury Statistics Query and Reporting System database of the Centers for Disease Control and Prevention. We defined trauma deaths as unintentional injuries, suicides, and homicides. RESULTS:: From 2000 to 2010, the US population increased by 9.7% and the number of trauma deaths increased by 22.8%. Trauma deaths and death rates deceased in individuals younger than 25 years but increased for those 25 years and older. During this period, death rates for cancer and heart disease decreased. The largest increases in trauma deaths were in individuals in their fifth and sixth decades of life. Since 2000, the largest proportional increase (118%) in crude trauma deaths occurred in 54-year-olds. Overall, in 2010, trauma was the leading cause of death in individuals 46 years and younger. Trauma remains the leading cause of years of life lost.Trauma is now the leading cause of death for individuals 46 years and younger. The largest increase in the number of trauma deaths and the highest crude number of trauma deaths occurred in baby boomers. Policy makers allocating resources should be made aware of the larger impact of trauma on our aging and burgeoning US population. Language: en

Superiority of frailty over age in predicting outcomes among geriatric trauma patients: a prospective analysis

Abstract: Importance The Frailty Index (FI) is a known predictor of adverse outcomes in geriatric patients. The usefulness of the FI as an outcome measure in geriatric trauma patients is unknown. Objective To assess the usefulness of the FI as an effective assessment tool in predicting adverse outcomes in geriatric trauma patients. Design, setting, and participants A 2-year (June 2011 to February 2013) prospective cohort study at a level I trauma center at the University of Arizona. We prospectively measured frailty in all geriatric trauma patients. Geriatric patients were defined as those 65 years or older. The FI was calculated using 50 preadmission frailty variables. Frailty in patients was defined by an FI of 0.25 or higher. Main outcomes and measures The primary outcome measure was in-hospital complications. The secondary outcome measure was adverse discharge disposition. In-hospital complications were defined as cardiac, pulmonary, infectious, hematologic, renal, and reoperation. Adverse discharge disposition was defined as discharge to a skilled nursing facility or in-hospital mortality. Multivariate logistic regression was used to assess the relationship between the FI and outcomes. Results In total, 250 patients were enrolled, with a mean (SD) age of 77.9 (8.1) years, median Injury Severity Score of 15 (range, 9-18), median Glasgow Coma Scale score of 15 (range, 12-15), and mean (SD) FI of 0.21 (0.10). Forty-four percent (n = 110) of patients had frailty. Patients with frailty were more likely to have in-hospital complications (odds ratio, 2.5; 95% CI, 1.5-6.0; P = .001) and adverse discharge disposition (odds ratio, 1.6; 95% CI, 1.1-2.4; P = .001). The mortality rate was 2.0% (n = 5), and all patients who died had frailty. Conclusions and relevance The FI is an independent predictor of in-hospital complications and adverse discharge disposition in geriatric trauma patients. This index should be used as a clinical tool for risk stratification in this patient group.

Improvements in early mortality and coagulopathy are sustained better in patients with blunt trauma after institution of a massive transfusion protocol in a civilian level I trauma center.

Abstract: Introduction:Transfusion practices across the country are changing with aggressive use of plasma (fresh-frozen plasma [FFP]) and platelets during massive transfusion with current military recommendations to use component therapy at a 1:1:1 ratio of packed red blood cells to FFP to platelets.Methods:

Validating Trauma-Specific Frailty Index for Geriatric Trauma Patients: A Prospective Analysis

Abstract: Background The Frailty Index has been shown to predict discharge disposition in geriatric patients. The aim of this study was to validate the modified 15-variable Trauma-Specific Frailty Index (TSFI) to predict discharge disposition in geriatric trauma patients. We hypothesized that TSFI can predict discharge disposition in geriatric trauma patients. Study Design We performed a 2-year (2011–2013) prospective analysis of all geriatric trauma patients presenting to our Level I trauma center. Patient discharge disposition was dichotomized into unfavorable (discharge to skilled nursing facility or death) and favorable (discharge to home or rehabilitation center) discharge disposition. Patients were evaluated using the developed 15-variable TSFI. Multivariate logistic regression was performed to identify factors that predict unfavorable discharge disposition. Results A total of 200 patients were enrolled for validation of TSFI. Mean age was 77 ± 12.1 years, median Injury Severity Score was 15 (interquartile range [IQR] 9 to 20), median Glasgow Coma Scale score was 14 (IQR 13 to 15), and median Frailty Index score was 0.20 (IQR 0.17 to 0.28); 29.5% (n = 59) patients had unfavorable discharge. After adjusting for age, sex, Injury Severity Score, Head Abbreviated Injury Scale, and vitals on admission, Frailty Index (odds ratio = 1.5; 95% CI, 1.1–2.5) was the only significant predictor for unfavorable discharge disposition. Age (odds ratio = 1.2; 95% CI, 0.9–3.1; p = 0.2) was not predictive of unfavorable discharge disposition. Conclusions The 15-variable TSFI is an independent predictor of unfavorable discharge disposition in geriatric trauma patients. The Trauma-Specific Frailty Index is an effective tool that can aid clinicians in planning discharge disposition of geriatric trauma patients.

A multidisciplinary clinical pathway decreases rib fracture-associated infectious morbidity and mortality in high-risk trauma patients.

Abstract: Background We initiated a multidisciplinary clinical pathway targeting patients greater than 45 years of age with more than 4 rib fractures. The purpose of the current study was to evaluate the effect of this pathway on infectious morbidity and mortality. Methods This was a prospective cohort study. Data evaluated included patient demographics, injury characteristics, pain management details, lengths of stay, morbidity, and mortality. Univariate and multivariate analyses were performed using a significance level of P Results When adjusting for age, injury severity score, and number of rib fractures, the clinical pathway was associated with decreased intensive care unit length of stay by 2.4 days (95% confidence interval [CI] −4.3, −0.52 days, P = .01) hospital length of stay by 3.7 days (95% CI −7.1, −0.42 days, P = .02), pneumonias (odds ratio [OR] 0.12, 95% CI 0.04 to 0.34, P P = .06). Conclusions Implementation of a rib fracture multidisciplinary clinical pathway decreased mechanical ventilator-dependent days, lengths of stay, infectious morbidity, and mortality.

Transfusion of plasma, platelets, and red blood cells in a 1: 1:1 vs a 1:1:2 ratio and mortality in patients with severe trauma: The PROPPR randomized clinical trial

Abstract: Importance Severely injured patients experiencing hemorrhagic shock often require massive transfusion. Earlier transfusion with higher blood product ratios (plasma, platelets, and red blood cells), defined as damage control resuscitation, has been associated with improved outcomes; however, there have been no large multicenter clinical trials. Objective To determine the effectiveness and safety of transfusing patients with severe trauma and major bleeding using plasma, platelets, and red blood cells in a 1:1:1 ratio compared with a 1:1:2 ratio. Design, Setting, and Participants Pragmatic, phase 3, multisite, randomized clinical trial of 680 severely injured patients who arrived at 1 of 12 level I trauma centers in North America directly from the scene and were predicted to require massive transfusion between August 2012 and December 2013. Interventions Blood product ratios of 1:1:1 (338 patients) vs 1:1:2 (342 patients) during active resuscitation in addition to all local standard-of-care interventions (uncontrolled). Main Outcomes and Measures Primary outcomes were 24-hour and 30-day all-cause mortality. Prespecified ancillary outcomes included time to hemostasis, blood product volumes transfused, complications, incidence of surgical procedures, and functional status. Results No significant differences were detected in mortality at 24 hours (12.7% in 1:1:1 group vs 17.0% in 1:1:2 group; difference, −4.2% [95% CI, −9.6% to 1.1%]; P = .12) or at 30 days (22.4% vs 26.1%, respectively; difference, −3.7% [95% CI, −10.2% to 2.7%]; P = .26). Exsanguination, which was the predominant cause of death within the first 24 hours, was significantly decreased in the 1:1:1 group (9.2% vs 14.6% in 1:1:2 group; difference, −5.4% [95% CI, −10.4% to −0.5%]; P = .03). More patients in the 1:1:1 group achieved hemostasis than in the 1:1:2 group (86% vs 78%, respectively; P = .006). Despite the 1:1:1 group receiving more plasma (median of 7 U vs 5 U, P P Conclusions and Relevance Among patients with severe trauma and major bleeding, early administration of plasma, platelets, and red blood cells in a 1:1:1 ratio compared with a 1:1:2 ratio did not result in significant differences in mortality at 24 hours or at 30 days. However, more patients in the 1:1:1 group achieved hemostasis and fewer experienced death due to exsanguination by 24 hours. Even though there was an increased use of plasma and platelets transfused in the 1:1:1 group, no other safety differences were identified between the 2 groups.

The European guideline on management of major bleeding and coagulopathy following trauma: fourth edition

Abstract: Severe trauma continues to represent a global public health issue and mortality and morbidity in trauma patients remains substantial. A number of initiatives have aimed to provide guidance on the management of trauma patients. This document focuses on the management of major bleeding and coagulopathy following trauma and encourages adaptation of the guiding principles to each local situation and implementation within each institution. The pan-European, multidisciplinary Task Force for Advanced Bleeding Care in Trauma was founded in 2004 and included representatives of six relevant European professional societies. The group used a structured, evidence-based consensus approach to address scientific queries that served as the basis for each recommendation and supporting rationale. Expert opinion and current clinical practice were also considered, particularly in areas in which randomised clinical trials have not or cannot be performed. Existing recommendations were reconsidered and revised based on new scientific evidence and observed shifts in clinical practice; new recommendations were formulated to reflect current clinical concerns and areas in which new research data have been generated. This guideline represents the fourth edition of a document first published in 2007 and updated in 2010 and 2013. The guideline now recommends that patients be transferred directly to an appropriate trauma treatment centre and encourages use of a restricted volume replacement strategy during initial resuscitation. Best-practice use of blood products during further resuscitation continues to evolve and should be guided by a goal-directed strategy. The identification and management of patients pre-treated with anticoagulant agents continues to pose a real challenge, despite accumulating experience and awareness. The present guideline should be viewed as an educational aid to improve and standardise the care of the bleeding trauma patients across Europe and beyond. This document may also serve as a basis for local implementation. Furthermore, local quality and safety management systems need to be established to specifically assess key measures of bleeding control and outcome. A multidisciplinary approach and adherence to evidence-based guidance are key to improving patient outcomes. The implementation of locally adapted treatment algorithms should strive to achieve measureable improvements in patient outcome.

The injury fact book

Abstract: This book includes detailed information on many of the factors surrounding injuries--the man-made systems and products involved, the groups at greatest risk, and effective ways to protect people from injuries. The circumstances under which injuries occur, the etiologic agents, and the characteristics of the people involved are examined. Chapter 2 summarizes the importance of injuries in relation to other prominent health problems. Subsequent chapters describe injury mortality and, in cases where good population-based studies are available, nonfatal injuries. The analyses in Chapters 3-15 are primarily of injury deaths during 1977-1979, the most recent years for which detailed mortality data were available in mid-1983 for deaths other than those related to motor vehicles. Most of these data were collected by the U.S. Department of Health and Human Services, National Center for Health Statistics (NCHS). Chapters 16-20 summarize data on deaths from motor vehicle-related injuries. Most of these detailed data were obtained from the U.S. Department of Transportation, National Highway Traffic Safety Administration (NHTSA). Data from the 1980 census provided denominators for the rates throughout the book, except for trendline calculations which were based on interpolations between census years. The purpose of this book is to improve understanding of the nature and magnitude of the injury problem in the United States. Although it includes some discussion of ameliorative approaches, there is no comprehensive coverage of injury research, theory, or prevention, since these have been comprehensively discussed elsewhere. This book is a thorough documentation of the injury problem. Most of the information presented is new, the product of analyses not previously published in any form.

Management of severe perioperative bleeding Guidelines from the European Society of Anaesthesiology

Abstract: The aims of severe perioperative bleeding management are three-fold. First, preoperative identification by anamesis and laboratory testing of those patients for whom the perioperative bleeding risk may be increased. Second, implementation of strategies for correcting preoperative anaemia and stabilisation of the macro- and microcirculations in order to optimise the patient’s tolerance to bleeding. Third, targeted procoagulant interventions to reduce the amount of bleeding, morbidity, mortality and costs. The purpose of these guidelines is to provide an overview of current knowledge on the subject with an assessment of the quality of the evidence in order to allow anaesthetists throughout Europe to integrate this knowledge into daily patient care wherever possible. The Guidelines Committee of the European Society of Anaesthesiology (ESA) formed a task force with members of scientific subcommittees and individual expert members of the ESA. Electronic databases were searched without language restrictions from the year 2000 until 2012. These searches produced 20 664 abstracts. Relevant systematic reviews with meta-analyses, randomised controlled trials, cohort studies, case-control studies and cross-sectional surveys were selected. At the suggestion of the ESA Guideline Committee, the Scottish Intercollegiate Guidelines Network (SIGN) grading system was initially used to assess the level of evidence and to grade recommendations. During the process of guideline development, the official position of the ESA changed to favour the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. This report includes general recommendations as well as specific recommendations in various fields of surgical interventions. The final draft guideline was posted on the ESA website for four weeks and the link was sent to all ESA members. Comments were collated and the guidelines amended as appropriate. When the final draft was complete, the Guidelines Committee and ESA Board ratified the guidelines.

The prospective, observational, multicenter, major trauma transfusion (PROMMTT) study: Comparative effectiveness of a time-varying treatment with competing risks

Abstract: Objective To relate in-hospital mortality to early transfusion of plasma and/or platelets and to time-varying plasma:red blood cell (RBC) and platelet:RBC ratios. Design Prospective cohort study documenting the timing of transfusions during active resuscitation and patient outcomes. Data were analyzed using time-dependent proportional hazards models. Setting Ten US level I trauma centers. Patients Adult trauma patients surviving for 30 minutes after admission who received a transfusion of at least 1 unit of RBCs within 6 hours of admission (n = 1245, the original study group) and at least 3 total units (of RBCs, plasma, or platelets) within 24 hours (n = 905, the analysis group). Main Outcome Measure In-hospital mortality. Results Plasma:RBC and platelet:RBC ratios were not constant during the first 24 hours (P Conclusions Higher plasma and platelet ratios early in resuscitation were associated with decreased mortality in patients who received transfusions of at least 3 units of blood products during the first 24 hours after admission. Among survivors at 24 hours, the subsequent risk of death by day 30 was not associated with plasma or platelet ratios.
