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

BACKGROUND\nImmunosuppression is a consequence of allogeneic (homologous) blood transfusion (ABT) in humans and is associated with an increased risk in cancer recurrence rates after potentially curative surgery as well as an increase in the frequency of postoperative bacterial infections. Although a meta-analysis has been reported demonstrating the relationship between ABT and colon cancer recurrence, no meta-analysis has been reported demonstrating the relationship of ABT to postoperative bacterial infection.\n\n\nMETHODS\nTwenty peer-reviewed articles published from 1986 to 2000 were included in a meta-analysis. Criteria for inclusion included a clearly defined control group (nontransfused) compared with a treated (transfused) group and statistical analysis of accumulated data that included stepwise multivariate logistic regression analysis. In addition, a subgroup of publications that included only the traumatically injured patient was included in a separate meta-analysis. A fixed effects analysis was conducted with odds ratios obtained by using the conditional maximum likelihood method and 95% confidence intervals on the obtained odds ratios were determined using the mid-p technique.\n\n\nRESULTS\nThe total number of subjects included in this meta-analysis was 13,152 (5,215 in the transfused group and 7,937 in the nontransfused group). The common odds ratio for all articles included in this meta-analysis evaluating the association of ABT to the incidence of postoperative bacterial infection was 3.45 (range, 1.43-15.15), with 17 of the 20 studies demonstrating a value of p < or = 0.05. These results provide overwhelming evidence that ABT is associated with a significantly increased risk of postoperative bacterial infection in the surgical patient. The common odds ratio of the subgroup of trauma patients was 5.263 (range, 5.03-5.43), with all studies showing a value of p < 0.05 (0.005-0.0001). These results demonstrate that ABT is associated with a greater risk of postoperative bacterial infection in the trauma patient when compared with those patients receiving ABT during or after elective surgery.\n\n\nCONCLUSION\nThese results demonstrate that ABT is an associated and apparently significant and frequently overlooked risk factor for the development of postoperative bacterial infection in the surgical patient. Allogeneic blood transfusion is a greater risk factor in the traumatically injured patient when compared with the elective surgical patient for the development of postoperative bacterial infection.

Frailty represents one of the most critical issues facing health care due to its inherent relationship with poor health care outcomes. Frailty is present in 10% to 20% of individuals 65 years and older1,2 and increases with advancing age. Currently, 15% of the United States population is 65 years and older; a number that is forecast to increase to 21% by the year 2030.3

Frailty for Surgeons: Review of a National Institute on Aging Conference on Frailty for Specialists.

Summary Normal haemostasis depends on an intricate balance between mechanisms of bleeding and mechanisms of thrombosis, and this balance can be altered after traumatic brain injury (TBI). Impaired haemostasis could exacerbate the primary insult with risk of initiation or aggravation of bleeding; anticoagulant use at the time of injury can also contribute to bleeding risk after TBI. Many patients with TBI have abnormalities on conventional coagulation tests at admission to the emergency department, and the presence of coagulopathy is associated with increased morbidity and mortality. Further blood testing often reveals a range of changes affecting platelet numbers and function, procoagulant or anticoagulant factors, fibrinolysis, and interactions between the coagulation system and the vascular endothelium, brain tissue, inflammatory mechanisms, and blood flow dynamics. However, the degree to which these coagulation abnormalities affect TBI outcomes and whether they are modifiable risk factors are not known. Although the main challenge for management is to address the risk of hypocoagulopathy with prolonged bleeding and progression of haemorrhagic lesions, the risk of hypercoagulopathy with an increased prothrombotic tendency also warrants consideration.

Excess Lactate: An Index of Reversibility of Shock in Human Patients.

BACKGROUND: Heart rate and systolic blood pressure are unreliable in geriatric trauma patients. Shock index (SI) (heart rate/systolic blood pressure) is a simple marker of worse outcomes after injury. The aim of this study was to assess the utility of SI in predicting outcomes. We hypothesized that SI predicts mortality in geriatric trauma patients. METHODS: We performed a 4-year (2007-2010) retrospective analysis using the National Trauma Data Bank. Patients 65 years or older were included. Transferred patients, patients dead on arrival, missing vitals on presentation, and patients with burns and traumatic brain injury were excluded. A cutoff value of SI greater than or equal to 1 (sensitivity, 81%; specificity, 79%) was used to define hemodynamic instability. The primary outcome measure was mortality. Secondary outcome measures were need for blood transfusion, need for exploratory laparotomy, and development of in-hospital complications. Multiple logistic regressions were performed. RESULTS: A total of 485,595 geriatric patients were reviewed, of whom 217,190 were included. The mean (SD) age was 77.7 (7.1) years, 60% were males, median Glasgow Coma Scale (GCS) score was 14 (range, 3-15), median Injury Severity Score (ISS) was 9 (range, 4-18), and mean (SD) SI was 0.58 (0.18). Three percent (n = 6,585) had an SI greater than or equal to 1. Patients with SI greater than or equal to 1 were more likely to require blood product requirement (p = 0.001), require an exploratory laparotomy (p = 0.01), and have in-hospital complications (p = 0.02). The overall mortality rate was 4.1% (n = 8,952). SI greater than or equal to 1 was the strongest predictor for mortality (odds ratio, 3.1; 95% confidence interval, 2.6-3.3; p = 0.001) in geriatric trauma patients. Systolic blood pressure (p = 0.09) and heart rate (p = 0.2) were not predictive of mortality. CONCLUSION: SI is an accurate and specific predictor of morbidity and mortality in geriatric trauma patients. SI is superior to heart rate and systolic blood pressure for predicting mortality in geriatric trauma patients. Geriatric trauma patients with SI greater than or equal to 1 should be transferred to a Level 1 trauma center. LEVEL OF EVIDENCE: Prognostic/epidemiologic study, level III. Language: en

Shock index predicts mortality in geriatric trauma patients: an analysis of the National Trauma Data Bank

Objectives: The aim of this study was to assess the seasonal variation in emergency general surgery (EGS) admissions. Background: Seasonal variation in medical conditions is well established; however, its impact on EGS cases remains unclear. Methods: The National Inpatient Sample (NIS) database was queried over an 8-year period (2004–2011) for all patients with diagnosis of acute appendicitis, acute cholecystitis, and diverticulitis. Elective admissions were excluded. The following data for each admission were recorded: age, sex, race, admission month, major operative procedure, hospital region, and mortality. Seasons were defined as follows: Spring (March, April, May), Summer (June, July, August), Fall (September, October, November), and Winter (December, January, February). X11 procedure and spectral analysis were performed to confirm seasonal variation. Results: A total of 63,911,033 admission records were evaluated of which 493,569 were appendicitis, 395,838 were cholecystitis, and 412,163 were diverticulitis. Seasonal variation is confirmed in EGS (F = 159.12, P < 0.0001) admissions. In the subanalysis, seasonal variation was found in acute appendicitis (F = 119.62, P < 0.0001), acute cholecystitis (F = 37.13, P < 0.0001), and diverticulitis (F = 69.90,P < 0.0001). The average monthly EGS admission in Winter was 11,322 ± 674. The average monthly EGS admission in Summer was higher than that of Winter by 13.6% (n = 1542; 95% CI: 1180–1904, P < 0.001). Conclusions: Hospitalization due to EGS adheres to a consistent cyclical pattern, with more admissions occurring during the Summer months. Although the reasons for this variability are unknown, this information may be useful for hospital resource reallocation and staffing.

Helicopter transport has resulted in mortality benefit for trauma patients but is a costly investment. In this study, the authors identify minimally injured patients not benefiting from helicopter transport who can be safely transported via ground transportation and assess the cost-savings associated with ground transport. Using a six-year retrospective analysis of trauma patients presenting to the University of Arizona Level 1 trauma center, data was extracted on: demographic characteristics; admission vital signs; injury severity; mode of transfer; hospital length of stay; emergency department disposition; mortality; procedures performed; transport cost; and transfer distance. Among the results, the authors found that helicopter-transferred patients were younger, more severely injured, and had longer hospital and intensive care unit stays. For minimally-injured patients, no difference in hospital length of stay or early discharge was seen between the helicopter-transferred versus ground-transferred patients. The authors also identified an average helicopter transfer cost of $18,000, leading them to conclude that a savings of $4,860,000 could potentially result from not transporting minimally-injured patients via helicopter. They suggest the need for policies that identify and select patients who would not benefit from helicopter transport, which will reduce health service delivery costs.

OBJECTIVES: To determine whether frail elderly adults are at greater risk of fracture after a ground-level fall (GLF) than those who are not frail. DESIGN: Prospective observational study. SETTING: Level 1 trauma center. PARTICIPANTS: All elderly (≥65) adults presenting after a GLF over 1 year (N = 110; mean age ± SD 79.5 ± 8.3, 54% male). MEASUREMENT: A Frailty Index (FI) was calculated using 50 preadmission frailty variables. Participants with a FI of 0.25 or greater were considered to be frail. The primary outcome measure was a new fracture; 40.1% (n = 45) of participants presented with a new fracture. The secondary outcome was discharge to an institutional facility (rehabilitation center or skilled nursing facility). Multivariate logistic regression was performed. RESULTS: Forty-three (38.2%) participants were frail. The median Injury Severity Score was 14 (range 9-17), and the mean FI was 0.20 ± 0.12. Frail participants were more likely than those who were not frail to have fractures (odds ratio (OR) = 1.8, 95% confidence interval (CI) = 1.2-2.3, P = .01). Thirty-six (32.7%) participants were discharged to an institutional facility. Frail participants were more likely to be discharged to an institutional facility (OR = 1.42, 95% CI = 1.08-3.09, P = .03) after a GLF. CONCLUSION: Frail individuals have a higher likelihood of fractures and discharge to an institutional facility after a GLF than those who are not frail. The FI may be used as an adjunct for decision-making when developing a discharge plan for an elderly adult after a GLF. Language: en

Managing older adults with ground-level falls admitted to a trauma service: the effect of frailty.

BACKGROUND: Differences in outcomes among trauma centers (TCs) and non-TCs (NTCs) in patients undergoing emergency general surgery (EGS) are well established. However; the impact of development of certified acute care surgery (ACS) programs on patient outcomes remains unknown. The aim of this study was to evaluate outcomes in patients undergoing EGS across TCs, NTCs, and TCs with ACS (ACS-TC). METHODS: National estimates for EGS procedures were abstracted from the National Inpatient Sample database. Patients undergoing emergent procedures (appendectomy, cholecystectomy, hernia repair, as well as small and large bowel resections) were included. TCs were identified based on American College of Surgeons' verification. ACS-TC programs were recorded from the American Association for the Surgery of Trauma. Outcome measures were hospital length of stay, complications, and mortality. Regression analysis was performed after adjusting for age, sex, race, Charlson comorbidity index, and type of procedure. RESULTS: A total of 131,410 patients undergoing EGS were analyzed. Patients managed in ACS-TCs had shorter hospital stay (p = 0.045) and lower complication rate (p = 0.041) compared with patients managed in both TCs and NTCs. There was no difference in mortality in patients managed across the groups; however, there was a trend toward lower mortality in patients managed in ACS-TCs in comparison with TCs (p = 0.064) and NTCs (p = 0.089). The overall hospital costs were lower for patients managed in ACS-TCs compared with TCs (p = 0.036). CONCLUSION: TCs with ACS have improved outcomes in EGS procedures compared with both TCs and non-TCs. ACS training with the associated infrastructure standards may contribute to these improved outcomes. LEVEL OF EVIDENCE: Therapeutic/care management study, level IV.
