Abstract Background A threshold Injury Severity Score (ISS) ≥ 16 is common in classifying major trauma (MT), although the Abbreviated Injury Scale (AIS) has been extensively revised over time. The aim of this study was to determine effects of different AIS revisions (1998, 2008 and 2015) on clinical outcome measures. Methods A retrospective observational cohort study including all primary admitted trauma patients was performed (in 2013–2014 AIS98 was used, in 2015–2016 AIS08, AIS08 mapped to AIS15). Different ISS thresholds for MT and their corresponding observed mortality and intensive care (ICU) admission rates were compared between AIS98, AIS08, and AIS15 with Chi-square tests and logistic regression models. Results Thirty-nine thousand three hundred seventeen patients were included. Thresholds ISS08 ≥ 11 and ISS15 ≥ 12 were similar to a threshold ISS98 ≥ 16 for in-hospital mortality (12.9, 12.9, 13.1% respectively) and ICU admission (46.7, 46.2, 46.8% respectively). AIS98 and AIS08 differed significantly for in-hospital mortality in ISS 4–8 (χ2 = 9.926, p = 0.007), ISS 9–11 (χ2 = 13.541, p = 0.001), ISS 25–40 (χ2 = 13.905, p = 0.001) and ISS 41–75 (χ2 = 7.217, p = 0.027). Mortality risks did not differ significantly between AIS08 and AIS15. Conclusion ISS08 ≥ 11 and ISS15 ≥ 12 perform similarly to a threshold ISS98 ≥ 16 for in-hospital mortality and ICU admission. This confirms studies evaluating mapped datasets, and is the first to present an evaluation of implementation of AIS15 on registry datasets. Defining MT using appropriate ISS thresholds is important for quality indicators, comparing datasets and adjusting for injury severity. Level of evidence Prognostic and epidemiological, level III.

BackgroundMore than a quarter of the UK population are affected by depression during their lifetime. For major trauma patients, postinjury depression can result in poorer long-term outcomes, but there is limited evidence regarding outcomes for patients with pre-existing depression. This study investigated the relationship between a diagnosis of depression prior to hospital admission and clinical outcomes after major trauma.MethodsTrauma patients at a UK major trauma center were identified during a 6.5-year period using the Trauma Audit and Research Network database. Patients with Injury Severity Score >15 who did not die in the emergency department (ED) were included. Logistic regression models were used to compare in-hospital mortality (excluding ED), requirement for surgery, and length of stay (LOS) between those with depression and those without.ResultsThere were 4602 patients included in the study and 6.45% had a diagnosis of depression. Depression was associated with a significant reduction in mortality (OR 0.54, 95% CI 0.30 to 0.91; p=0.026). However, patients with depression were more likely to have longer LOS (OR 124, 95% CI 8.5 to 1831; p<0.001) and intensive care unit LOS (OR 9.69, 95% CI 3.14 to 29.9; p<0.001). Patients with depression were also more likely to undergo surgery (OR 1.36, 95% CI 1.06 to 1.75; p=0.016).DiscussionA pre-existing diagnosis of depression has complex association with clinical outcomes after major trauma, with reduced mortality but longer LOS and higher likelihood of surgical intervention. Further prospective investigations are warranted to inform optimal management strategies for major trauma patients with pre-existing depression.Level of evidenceIII.

BackgroundThe risk of death and complications after major trauma in patients with chronic kidney disease (CKD) is higher than in the general population, but whether this association holds true among Canadian trauma patients is unknown.ObjectivesTo characterize patients with CKD/receiving dialysis within a regional major trauma cohort and compare their outcomes with patients without CKD.MethodsAll major traumas requiring hospitalization between 2006 and 2017 were identified from a provincial trauma registry in Nova Scotia, Canada. Trauma patients with stage ≥3 CKD (estimated glomerular filtration rate <60 mL/min/1.73 m2) or receiving dialysis were identified by cross-referencing two regional databases for nephrology clinics and dialysis treatments. The primary outcome was in-hospital mortality; secondary outcomes included hospital/intensive care unit (ICU) length of stay (LOS) and ventilator-days. Cox regression was used to adjust for the effects of patient characteristics on in-hospital mortality.ResultsIn total, 6237 trauma patients were identified, of whom 4997 lived within the regional nephrology catchment area. CKD/dialysis trauma patients (n=101; 28 on dialysis) were older than patients without CKD (n=4896), with higher rates of hypertension, diabetes, and cardiovascular disease, and had increased risk of in-hospital mortality (31% vs 11%, p<0.001). No differences were observed in injury severity, ICU LOS, or ventilator-days. After adjustment for age, sex, and injury severity, the HR for in-hospital mortality was 1.90 (95% CI 1.33 to 2.70) for CKD/dialysis compared with patients without CKD.ConclusionIndependent of injury severity, patients without CKD/dialysis have significantly increased risk of in-hospital mortality after major trauma.

Background: Some articles proved indirect-transfer the major trauma patients to the trauma centers had non-significant different outcomes with the patients direct-transfer to the centers. But the outcomes for the major trauma patients in the counties without trauma centers still can be worse. So we did a population based research by using the NHIRD data for the results. Methods: From the claim data of one million beneficiaries of Taiwan National Health Insurance during the year of 2006 to 2008, all of the trauma patients were identified from the database by the ICD-9-CM system. ICDMAP-90 was used for calculating the Injury Severity Score (ISS) as the variable controlling the disease severity. The patients of major trauma were defined as ISS more than fifteen. We used the diagnosis one year before the trauma admission for calculating Charlson Comorbidity Index (CCI). The first hospitals and the second transferred hospitals that the major trauma patients admitted, and the areas of the first hospitals were recognized in our data bank. The condition of transfer, age, genders, intubation, ICU admission, ISS, CCI, and the triage classifications were adjusted in a logistic regression model for further analysis. Results: There were 2497 major trauma patients (ISS more then 15). The total mortality rate was 12.49%. The variables like age, intubation, ICU admission, ISS and CCI were significant for mortality, but the condition of transfer was not significant in our model. After controlling all the factors, the major trauma patients that first admitted in the areas with no trauma centers have a significant higher risk of mortality (OR=1.73, P=0.005). Conclusions: Our results hint that, although indirect-transfer for the major trauma patients have insignificant difference in mortality with the direct transfer patients, the counties with no trauma centers have significant higher mortality rates in major trauma patients. Further researches are needed for investigating the possible reasons.

Abstract This was a retrospective study of pediatric trauma patients and were hospitalized in a level-1 trauma center from January 1, 2009 to December 31, 2016. Stress-induced hyperglycemia (SIH) was defined as a hyperglycemia level ≥200 mg/dL upon arrival at the emergency department without any history of diabetes or a hemoglobin A1c level ≥6.5% upon arrival or during the first month of admission. The results demonstrated that the patients with SIH (n = 36) had a significantly longer length of stay (LOS) in hospital (16.4 vs. 7.8 days, p = 0.002), higher rates of intensive care unit (ICU) admission (55.6% vs. 20.9%, p < 0.001), and higher in-hospital mortality rates (5.6% vs. 0.6%, p = 0.028) compared with those with non-diabetic normoglycemia (NDN). However, in the 24-pair well-balanced propensity score-matched patient populations, in which significant difference in sex, age, and injury severity score were eliminated, patient outcomes in terms of LOS in hospital, rate of ICU admission, and in-hospital mortality rate were not significantly different between the patients with SIH and NDN. The different baseline characteristics of the patients, particularly injury severity, may be associated with poorer outcomes in pediatric trauma patients with SIH compared with those with NDN. This study also indicated that, upon major trauma, the response of pediatric patients with SIH is different from that of adult patients.

ObjectiveHypoalbuminaemia is an important prognostic factor. It may be associated with poor nutritional states, chronic heart and kidney disease, long-standing infection and cancer. Hypotension is a hallmark of circulatory failure. We evaluated hypoalbuminaemia and hypotension synergism as predictor of in-hospital mortality and intensive care unit (ICU) admission.DesignWe retrospectively analysed emergency department (ED) visits from January 2011 to December 2019.SettingData were retrieved from five Mount Sinai health system hospitals, New York.ParticipantsWe included consecutive ED patients ≥18 years with albumin measurements.Primary and secondary outcome measuresClinical outcomes were in-hospital mortality and ICU admission. The rates of these outcomes were stratified by systolic blood pressure (SBP) (<90 vs ≥90 mm Hg) and albumin levels. Variables included demographics, presenting vital signs, comorbidities (measured as ICD codes) and other common blood tests. Multivariable logistic regression models analysed the adjusted OR of different levels of albumin and SBP for predicting ICU admission and in-hospital mortality. The models were adjusted for demographics, vital signs, comorbidities and common laboratory results. Patients with albumin 3.5–4.5 g/dL and SBP ≥90 mm Hg were used as reference.ResultsThe cohort included 402 123 ED arrivals (27.9% of total adult ED visits). The rates of in-hospital mortality, ICU admission and overall admission were 1.7%, 8.4% and 47.1%, respectively. For SBP <90 mm Hg and albumin <2.5 g/dL, mortality and ICU admission rates were 34.0% and 40.6%, respectively; for SBP <90 mm Hg and albumin ≥2.5 g/dL 8.2% and 24.1%, respectively; for SBP ≥90 mm Hg and albumin <2.5 g/dL 11.4% and 18.6%, respectively; for SBP ≥90 mm Hg and albumin 3.5–4.5 g/dL 0.5% and 6.4%, respectively. Multivariable analysis showed that in patients with hypotension and albumin <2.5 g/dL the adjusted OR for in-hospital mortality was 37.1 (95% CI 32.3 to 42.6), and for ICU admission was 5.4 (95% CI 4.8 to 6.1).ConclusionCo-occurrence of hypotension and hypoalbuminaemia is associated with poor hospital outcomes.

Prediction Of Mortality

Introduction The neutrophil-to-lymphocyte ratio (NLR) has been proposed as a marker of systemic inflammation in major trauma patients that is associated with in-hospital mortality. We aimed to determine the discriminative ability of initial NLR as a predictor of outcomes following major trauma. Methods This was a registry-based cohort study involving all major trauma patients meeting criteria for inclusion into the Alfred Health Trauma Registry who presented directly from the scene of injury over a 24-month period (January 2018 to December 2019). The initial NLR was calculated for each patient and was compared against the Shock Index (SI), lactate and Revised Trauma Score (RTS). Outcomes observed were mortality at hospital discharge and intensive care unit (ICU) admission. We assessed the predictive capacity of each test using the receiver operating characteristic (ROC) curve and performed area under the ROC curve (AUROC) analysis to compare their performance. Results Data were extracted for 1687 major trauma patients, of which 72% were male, the median age was 49 years (IQR 31–68) and most (90%) of patients presented after a blunt mechanism of injury. In-hospital mortality occurred in 165 (9.77%) patients, and 725 (42.92%) patients required ICU admission. The median NLR was 6.84 (IQR 3.89–11.52). Initial NLR performed poorly with an AUROC of 0.46 (95% confidence interval (CI): 0.40–0.52) for prediction of mortality and AUROC of 0.53 (95% CI: 0.50–0.56) for prediction of ICU admission. The AUROCs of initial NLR for both mortality at hospital discharge and ICU admission were significantly lower than SI, lactate and RTS. Conclusion Initial NLR was not predictive of outcomes in major trauma. NLR at other time-points may provide better predictive capacity for outcomes.

BackgroundOvertriage of trauma patients is unavoidable and requires effective use of hospital resources. A ‘pit stop’ (PS) was added to our lowest tier trauma resource (TR) triage protocol where the patient stops in the trauma bay for immediate evaluation by the emergency department (ED) physician and trauma nursing. We hypothesized this would allow for faster diagnostic testing and disposition while decreasing cost.MethodsWe performed a before/after retrospective comparison after PS implementation. Patients not meeting trauma activation (TA) criteria but requiring trauma center evaluation were assigned as a TR for an expedited PS evaluation. A board-certified ED physician and trauma/ED nurse performed an immediate assessment in the trauma bay followed by performance of diagnostic studies. Trauma surgeons were readily available in case of upgrade to TA. We compared patient demographics, Injury Severity Score, time to physician evaluation, time to CT scan, hospital length of stay, and in-hospital mortality. Comparisons were made using 95% CI for variance and SD and unpaired t-tests for two-tailed p values, with statistical difference, p<0.05.ResultsThere were 994 TAs and 474 TRs in the first 9 months after implementation. TR’s preanalysis versus postanalysis of the TR group shows similar mean door to physician evaluation times (6.9 vs. 8.6 minutes, p=0.1084). Mean door to CT time significantly decreased (67.7 vs. 50 minutes, p<0.001). 346 (73%) TR patients were discharged from ED; 2 (0.4%) were upgraded on arrival. When admitted, TR patients were older (61.4 vs. 47.2 years, p<0.0001) and more often involved in a same-level fall (59.5% vs. 20.1%, p<0.0001). Undertriage was calculated using the Cribari matrix at 3.2%.DiscussionPS implementation allowed for faster door to CT time for trauma patients not meeting activation criteria without mobilizing trauma team resources. This approach is safe, feasible, and simultaneously decreases hospital cost while improving allocation of trauma team resources.Level of evidenceLevel II, economic/decision therapeutic/care management study.

Introduction Trauma is one of the leading causes of mortality worldwide, but little is known of the temporal variation in major trauma across England, Wales and Northern Ireland. Proper workforce and infrastructure planning requires identification of the caseload burden and its temporal variation. Materials and Methods The Trauma Audit Research Network (TARN) database for admissions attending Major Trauma Centres (MTCs) between 1st April 2011 and 31st March 2018 was analysed. TARN records data on all trauma patients admitted to hospital who are alive at the time of admission to hospital. Major trauma was classified as an Injury Severity Score (ISS) >15. Results A total of 158,440 cases were analysed. Case ascertainment was over 95% for 2013 onwards. There was a statistically significant variation in caseload by year (p < 0.0001), times of admissions (p < 0.0001), caseload admitted during weekends vs weekdays, 53% vs 47% (p < 0.0001), caseload by season with most patients admitted during summer (p < 0.0001). The ISS varied by time of admission with most patients admitted between 1800 and 0559 (p < 0.0001), weekend vs weekday with more severely injured patients admitted during the weekend (p < 0.0001) and by season p < 0.0001). Discussion and Conclusion: There is a significant national temporal variation in major trauma workload. The reasons are complex and there are multiple theories and confounding factors to explain it. This is the largest dataset for hospitals submitting to TARN which can help guide workforce and resource allocation to further improve trauma outcomes.

Introduction Blunt diaphragm injury (BDI) is an uncommon, potentially fatal consequence of blunt torso injury. While associations between BDI and other factors such as mechanism of injury or other injuries have been described elsewhere, little recent research has been done in Australia into BDI. The aims of this study were to determine the incidence rate of BDI in our centre, identify how it was diagnosed, determine rates of missed injury and identify predictive factors for BDI. The hypothesis was that patients with BDI would significantly differ to those without BDI. Methods All major trauma patients with blunt torso injuries at our Level 1 major trauma service from 2010 to 2018 were included. Data for patient demographics, other injuries, diagnosis and treatment of BDI were extracted. Patients with BDI were compared with patients without BDI in order to identify differences that could be used to predict BDI in future patients. Results Of 5190 patients with a blunt torso injury, 51 (0.98%) had a BDI at a mean age of 53 ± 19.6 years, and median Injury Severity Score (ISS) of 27(IQR 21–38.5) compared with 5139 patients with a mean age of 48.2 ± 20.7 years and median ISS of 21.9(IQR 14–26) who did not have a BDI. The diagnosis of BDI was made at CT ( n = 35), surgery ( n = 14) or autopsy ( n = 2). Blunt diaphragm injury was missed on index imaging for 11 of 43 patients (25.6%). On multivariate analysis, each point increase in ISS (OR 1.03, p = 0.02); rib fractures (OR 4.65, p = 0.004); splenic injury (OR 2.60, p = 0.004); and liver injury (OR 2.78, p = 0.003) were independently associated with BDI. Conclusion Injury Severity Score, rib fractures and solid abdominal organ injury increase the likelihood of BDI. In patients with these injuries, BDI should be considered even in the presence of normal CT findings.

Stress Dose

Corticosteroids play an important role in responding to physiologic stress in the human body. However, its application in critical care remains heavily debated. The purpose of this study was to identify patient characteristics associated with receiving stress-dose steroids during the intensive care unit stay after traumatic injury and its effect on in-hospital mortality. Patients admitted to the University of Virginia trauma center between January 1, 2011, and December 31, 2015, were identified using our Trauma Registry. Stress dose steroids were defined as 100 mg IV hydrocortisone every eight hours. Patients who received stress-dose steroids were identified using the Clinical Data Repository. Patient characteristics associated with increased likelihood of receiving stress-dose steroids during admission were age >65, diabetes mellitus, congestive heart failure, burn injuries, Injury Severity Score >15, lower blood pressure (141/80 vs 125/76 mm Hg), and higher heart rate (87 vs 94/min). Patients who received stress-dose steroids were found to have increased mortality but not after controlling for the aforementioned patient factors associated with increased likelihood of receiving stress-dose steroids. The use of stress-dose steroids in critically ill patients with refractory hypotension does not appear to affect in-hospital mortality.
