Abstract: Background: The effect of β-blockade in trauma patients without significant head injuries is unknown. The purpose of this investigation was to determine the impact of β-blocker exposure on mortality in critically injured trauma patients who did not sustain significant head injuries. Methods: Critically ill trauma patients (Injury Severity Score ≥ 25) admitted to the surgical intensive care unit from January 2000 to December 2008 without severe traumatic brain injuries (head Abbreviated Injury Score ≥ 3) were included in this retrospective review. Patients who received β-blockers within 30 days of intensive care unit admission were compared with those who did not. The primary outcome measure evaluated was in-hospital mortality. Results: During the 9-year study period, 663 critically injured patients (Injury Severity Score ≥ 25) were admitted to the intensive care unit. Of these, 98 patients (14.8%) received β-blockers. Patients exposed to β-blockers had significantly lower in-hospital mortality (11.2% vs 19.3%, P = .006). Stepwise logistic regression identified β-blocker use as an independent protective factor for mortality (adjusted odds ratio, .37; P = .007) in critically injured patients. Conclusions: Beta-blocker exposure was associated with reduced mortality in critically injured patients without head injuries. Prospective validation of this finding is warranted.

Background: Conclusions from in vivo and in vitro studies suggest hypothermia may be protective in traumatic brain injury (TBI). Few studies evaluated the effect of admission temperature on outcomes. The purpose of this study is to examine the relationship between admission hypothermia and mortality in patients with isolated, blunt, moderate to severe TBI. Methods: The Los Angeles Trauma Database was queried for all patients ≥14 y of age with isolated, blunt, moderate to severe TBI (head abbreviated injury score (AIS) ≥3, all other <3), admitted between 2005 and 2009. The study population was then stratified into two groups by admission temperature: hypothermic (≤35°C) and normothermic (>35°C). Demographic characteristics and outcomes were compared between groups. Logistic regression analysis was used to determine the relationship between admission hypothermia and mortality. Results: A total of 1834 patients were analyzed and then stratified into two groups: hypothermic (n = 44) and normothermic (n = 1790). There was a significant difference noted in overall mortality (25% versus 7%), with the hypothermic group being four times more likely to succumb to their injuries. After adjusting for confounding factors, admission hypothermia was independently associated with increased mortality (AOR 2.5; 95% CI 1.1–6.3; P = 0.04). Conclusions: Although in-vivo and in-vitro studies demonstrate induced hypothermia may be protective in TBI, our study demonstrates that admission hypothermia was associated with increased mortality in isolated, blunt, moderate to severe TBI. Further prospective research is needed to elucidate the role of thermoregulation in patients sustaining TBI. [Copyright &y& Elsevier]

Background: This study reviews our 10-year institutional experience with damage control management and investigates risk factors for early mortality. Materials and Methods: The trauma registry of our level I trauma centre was utilized to identify all patients from 01/96 through 12/05 who underwent initial damage control procedures. Demographics, clinical and physiological parameters, and outcomes were abstracted. Patients were categorized as either early survivors (surviving the first 72 hours after admission) or early deaths. Results: During the study period, 319 patients underwent damage control management. Overall, 52 patients (16.3%) died (early deaths) and 267 patients (83.7%) survived the first 72 hours (early survivors). Early deaths showed significantly deranged serum lactate (5.81±0.55 vs. 3.46±0.13 mmol/L; P<0.001), base deficit (10.10±0.95 vs. 4.90±0.28 mmol/L; P<0.001) and pH (7.16±0.03 vs. 7.29±0.01; P<0.001) levels compared to early survivors on hospital admission. An International Normalized Ratio >1.2, base deficit >3 mmol/L, head Abbreviated Injury Scale ≥3, body temperature <35°C, serum lactate >6 mmol/L, and hemoglobin <7 g/dL proved to be independent risk factors for early mortality on hospital admission. Conclusions: Several risk factors for early mortality such as severe head injury and the lethal triad (coagulopathy, acidosis and hypothermia) in patients undergoing damage control procedures were identified and should trigger the trauma surgeon to maintain aggressive resuscitation in the intensive care unit.

Background: Early endotracheal intubation in patients sustaining moderate to severe traumatic brain injury (TBI) is considered the standard of care. Yet the benefit of pre-hospital intubation (PHI) in patients with TBI is questionable. The purpose of this study was to investigate the relationship between pre-hospital endotracheal intubation and mortality in patients with isolated moderate to severe TBI. Methods: The Los Angeles County Trauma System Database was queried for all patients > 14 y of age with isolated moderate to severe TBI admitted between 2005 and 2009. The study population was then stratified into two groups: those patients requiring intubation in the field (PHI group) and those patients with delayed airway management (No-PHI group). Demographic characteristics and outcomes were compared between groups. Multivariate analysis was used to determine the relationship between pre-hospital endotracheal intubation and mortality. Results: A total of 2549 patients were analyzed and then stratified into the two groups: PHI and No-PHI. There was a significant difference noted in overall mortality (90.2% versus 12.4%), with the PHI group being more likely to succumb to their injuries. After adjusting for possible confounding factors, multivariable logistic regression analysis demonstrated that PHI was independently associated with increased mortality (AOR 5, 95% CI: 1.7–13.7, P = 0.004). Conclusions: Pre-hospital endotracheal intubation in isolated, moderate to severe TBI patients is associated with a nearly 5-fold increase in mortality. Further prospective studies are required to establish guidelines for optimal pre-hospital management of this critically injured patient population. [Copyright &y& Elsevier]

Abstract: Background: Systemic hypotension is a well documented predictor of increased mortality following traumatic brain injury (TBI). Hypotension is traditionally defined as systolic blood pressure (SBP)<90mmHg. Recent evidence defines hypotension by a higher SBP in injured (non-TBI) trauma patients. We hypothesize that hypotension threshold requires a higher SBP in isolated moderate to severe TBI. Patients and methods: A retrospective database review of all adults (≥15 years) with isolated moderate to severe TBI (head abbreviated injury score (AIS)≥3, all other AIS≤3), admitted from five Level I and eight Level II trauma centres (Los Angeles County), between 1998 and 2005. Several fit statistic analyses were performed for each admission SBP from 60 to 180mmHg to identify the model that most accurately defined hypotension for three age groups: 15–49 years, 50–69 years, and ≥70 years. The main outcome variable was mortality, and the optimal definition of hypotension for each group was determined from the best fit model. Adjusted odds ratios (AOR) were then calculated to determine increased odds in mortality for the defined optimal SBP within each age group. Results: A total of 15,733 patients were analysed. The optimal threshold of hypotension according to the best fit model was SBP of 110mmHg for patients 15–49 years (AOR 1.98, CI 1.65–2.39, p <0.0001), 100mmHg for patients 50–69 years (AOR 2.20, CI 1.46–3.31, p =0.0002), and 110mmHg for patients ≥70 years (AOR 1.92, CI 1.35–2.74, p =0.0003). Conclusions: Patients with isolated moderate to severe TBI should be considered hypotensive for SBP<110mmHg. Further research should confirm this new definition of hypotension by correlation with indices of perfusion. [Copyright &y& Elsevier]

Abstract: Background: Complications after inferior vena cava (IVC) injury, including venous thromboembolism (VTE), are expected, but the exact incidence is poorly defined. The purpose of this study is to examine the VTE rate following ligation versus repair of IVC injuries. Materials and methods: The California State Inpatient Database was queried for all adult patients (age >14 y) admitted between 2005 and 2008 with IVC injuries. Demographic data, mechanism of injury, operative technique (ligation versus repair), and outcomes were recorded. Outcomes were compared according to operative technique. Results: A total of 308 patients with IVC injuries were evaluated. The study population was mostly male (81.2%), young (median age 24 y), and Hispanic (43.2%). Overall mortality was 37.3%. The mechanisms of injury included gunshot wounds (52.3%), stab wounds (14.0%), and motor vehicle collisions (14.9%). Associated injuries were present in 100% of cases, with duodenal injuries being the most common. The majority of injuries were managed by primary repair (76.6%), with ligation performed in 23.4%. Patients who underwent ligation had a longer hospital stay (median 9 versus 6 d, P = 0.04) and a trend towards a higher mortality (45.8% versus 34.8%, P = 0.10), with no difference in VTE rate (4.2% versus 1.7%, P > 0.99). Conclusions: As expected, IVC injuries carry a very high mortality rate and are always associated with other injuries. We demonstrated a surprisingly low rate of VTE after operative management for IVC injury, which was similar for patients undergoing ligation and repair. [Copyright &y& Elsevier]

Background In an expanding elderly population, traumatic brain injury (TBI) remains a significant cause of death and disability. Guidelines for management of TBI, according to the Brain Trauma Foundation (BTF), include intracranial pressure (ICP) monitoring. Whether ICP monitoring contributes to outcomes in the elderly patients with TBI has not been explored. Methods This is a retrospective study extracted from the National Trauma Database 2007–2008 research datasets. Patients were included if aged >55 y and they met BTF indications for ICP monitoring. Patients that had nonsurvivable injuries (any body region, abbreviated injury score = 6), were dead on arrival, had withdrawal of care, or length of stay <48 h were excluded. Outcomes were then stratified based on ICP monitoring. The primary outcomes were inhospital mortality and favorable discharge. Logistic regression was used to analyze the effect of ICP monitoring on outcomes. Results A total of 4437 patients were included with 11.2% having an ICP monitor placed. Patients requiring an ICP monitor were younger overall, more likely to present hypertensive, had higher injury severity, and more likely to require operative intervention. Median initial Glasgow coma scale (3) was similar between groups. Of those patients with ICP monitoring, overall mortality was significantly higher, and they were less likely to have favorable discharge status. Craniotomy itself was not associated with increased mortality ( P = 0.450). Conclusions Our findings suggest that the use of ICP monitoring according to BTF guidelines in elderly TBI patients does not provide outcomes superior to treatment without monitoring. The ideal group to benefit from ICP monitor placement remains to be elucidated. [ABSTRACT FROM AUTHOR]

Abstract: Introduction: Studies on blood product transfusions after trauma recommend targeting specific ratios to reduce mortality. Although crystalloid volumes as little as 1.5 L predict increased mortality after trauma, little data is available regarding the threshold of red blood cell (RBC) transfusion volume that predicts increased mortality. Materials and methods: Data from a level I trauma center between January 2000 and December 2008 were reviewed. Trauma patients who received at least 100 mL RBC in the emergency department (ED) were included. Each unit of RBC was defined as 300 mL. Demographics, RBC transfusion volume, and mortality were analyzed in the nonelderly (<70 y) and elderly (≥70 y). Multivariate logistic regression was performed at various volume cutoffs to determine whether there was a threshold transfusion volume that independently predicted mortality. Results: A total of 560 patients received ≥100 mL RBC in the ED. Overall mortality was 24.3%, with 22.5% (104 deaths) in the nonelderly and 32.7% (32 deaths) in the elderly. Multivariate logistic regression demonstrated that RBC transfusion of ≥900 mL was associated with increased mortality in both the nonelderly (adjusted odds ratio 2.06, P = 0.008) and elderly (adjusted odds ratio 5.08, P = 0.006). Conclusions: Although transfusion of greater than 2 units in the ED was an independent predictor of mortality, transfusion of 2 units or less was not. Interestingly, unlike crystalloid volume, stepwise increases in blood volume were not associated with stepwise increases in mortality. The underlying etiology for mortality discrepancies, such as transfusion ratios, hypothermia, or immunosuppression, needs to be better delineated. [Copyright &y& Elsevier]

Abstract: Introduction: High-dose vancomycin is increasingly prescribed for critically ill trauma patients at risk for methicillin-resistant Staphylococcus aureus pneumonia. Although trauma patients have multiple known risk factors for acute kidney injury (AKI), a link between vancomycin and AKI or mortality has not been established. We hypothesize that high vancomycin trough concentration (VT) after trauma is associated with AKI and increased mortality. Methods: This was a retrospective analysis from a single institution Level I trauma center. Data were reviewed for all adult trauma patients who were admitted between 2006 and 2010. Patients were included if they received intravenous vancomycin, had serum creatinine levels before and after vancomycin administration, and had at least one recorded VT. Patients were stratified by VT into four groups: VT1 = 0–10 mg/L, VT2 = 10.1–15 mg/L, VT3 = 15.1–20 mg/L, VT4 >20 mg/L. Multivariable logistic regression was performed to determine the association between VT, AKI, and mortality. Results: Of the 6781 trauma patients reviewed, 263 (3.9%) fit inclusion criteria. Ninety-seven (36.9%) patients developed AKI and 25 (9.5%) died. AKI and mortality increased progressively with VT. Ninety-one patients (34.6%) had troughs >20 mg/L and VT4 was independently associated with AKI (AOR 4.7, P < 0.01) and mortality (AOR 4.8, P = 0.05). Conclusion: AKI is common in trauma patients who receive intravenous vancomycin. A supratherapeutic trough level of >20 mg/L is an independent predictor of AKI and mortality in trauma patients.

Abstract: Background: In adult trauma, mortality varies with race and insurance status. In the elderly, insurance type has little impact on mortality after trauma and the influence of race is reduced. How race and insurance affect pediatric trauma requires further attention. We hypothesized that mortality after pediatric trauma is influenced by insurance type and not race. Methods: We reviewed all cases of blunt trauma in children ≤13 y requiring admission, using the National Trauma Data Bank Research Data Sets for 2007 and 2008. Exclusions included an Abbreviated Injury Score of 6 for any body region, dead on arrival, and missing data. Our primary outcome measure was in-hospital mortality. Results: We identified 831 Asian (1.2%), 10,592 black (15.5%), 45,173 white (66.2%), and 8498 Hispanic (12.5%) children, and 3161 children (4.6%) classified as other race. Mean age was 7.4 ± 4.5 y, 11.9% were uninsured, and overall in-hospital mortality was 1.4%. Multivariable modeling indicated that race was not associated with increased mortality (Asian versus white, adjusted odds ratio [AOR] 1.05, P = 0.88; black versus white, AOR 0.92, P = 0.42; Hispanic versus white, AOR 0.87, P = 0.26; and other race versus white, AOR 1.01, P = 0.96). In contrast, insurance status (any insurance versus no insurance, AOR 0.6, P < 0.01) and insurance type (private insurance versus no insurance, AOR 0.47, P < 0.01; Medicaid versus no insurance, 0.67, P < 0.01) predicted reduced mortality. Conclusions: Insurance status and insurance type are important predictors of mortality after pediatric trauma while, in contrast, race is not. [Copyright &y& Elsevier]

BACKGROUND: Alcohol intoxication in pediatric trauma is underappreciated. The aim of this study was to characterize alcohol screening rates in pediatric trauma METHODS: The Los Angeles County Trauma System Database was queried for all patients aged < 18 years who required admission between 2003 and 2008. Patients were compared by age and gender. RESULTS: A total of 18,598 patients met the inclusion criteria; 4,899 (26.3%) underwent blood alcohol screening, and 2,797 (57.1%) of those screened positive. Screening increased with age (3.3% for 0-9 years, 15.1% for 10-14 years, and 45.4% for 15-18 years; P < .01), as did alcohol intoxication (1.9% for 0-9 years, 5.8% 10-14 years, and 27.3% for 15-18 years; P < .01). Male gender predicted higher mortality in those aged 15 to 18 years (adjusted odds ratio, 1.7; P < .01), while alcohol intoxication did not (adjusted odds ratio, .97; P = .84). CONCLUSIONS: Alcohol intoxication is common in adolescent trauma patients. Screening is en-couraged for pediatric trauma patients aged >10 years who require admission. [ABSTRACT FROM AUTHOR]

Previous investigations suggest outcome differences at Level I and Level II trauma centers. We examined use of intracranial pressure (ICP) monitors at Level I and Level II trauma centers after traumatic brain injury (TBI) and its effect on mortality. The 2007 to 2008 National Trauma Data- bank was reviewed for patients with an indication for ICP monitoring based on Brain Trauma Foundation (BTF) guidelines. Demographic and clinical outcomes at Level I and Level II centers were compared by regression modeling. Overall, 15,921 patients met inclusion criteria; 11,017 were admitted to a Level I and 4,904 to a Level II trauma center. Patients with TBI admitted to a Level II trauma center had a lower rate of Injury Severity Score greater than 16 (80 vs 82%, P < 0.01) and lower frequency of head Abbreviated Injury Score greater than 3 (80 vs 82%, P < 0.01). After regression modeling, patients with TBI admitted to a Level II trauma center were 31 per cent less likely to receive an ICP monitor (adjusted odds ratio [AOR], 0.69; P < 0.01) and had a significantly higher mortality (AOR, 1.12; P < 0.01). Admission to a Level II trauma center after severe TBI is associated with a decreased use of ICP monitoring in patients who meet BTF criteria as well as an increased mortality. These differences should be validated prospectively to narrow these discrepancies in care and outcomes between Level I and Level II centers. [ABSTRACT FROM AUTHOR]

Abstract: Background: We undertook the current study to determine the impact of elevated admission systolic blood pressure (SBP) on trauma patients without severe brain injury. Materials and methods: We conducted a retrospective review of the Los Angeles County Trauma System database to identify all patients with moderate to severe injuries (injury severity score >9) admitted between 2003 and 2008. Patients with head abbreviated injury score >3 were excluded. We divided the remaining patients into three age cohorts and conducted multivariate regression modeling at increasing SBP thresholds to identify independent predictors of mortality. Results: A total of 23,931 patients met inclusion criteria. Overall mortality was 8.6% and it increased with age across the three groups. The admission SBP thresholds associated with significantly increased mortality in the young and middle-aged were >190 mm Hg (AOR 1.5, P = 0.04) and >180 mm Hg (AOR 1.5, P = 0.01), respectively. In the elderly, no admission SBP threshold was associated with significantly increased mortality. Interestingly, several elevated admission SBP thresholds were associated with significantly reduced mortality in the elderly (>150 mm Hg AOR 0.6, P < 0.01; >160 mm Hg AOR 0.6, P < 0.01; and >170 mm Hg AOR 0.7, P = 0.02). Conclusions: The admission SBP thresholds that predicted higher mortality for the young and middle-aged were >190 mm Hg and >180 mm Hg, respectively. Elderly trauma patients tolerated higher admission SBP than their younger counterparts and multiple elevated SBP thresholds were associated with significantly reduced mortality in the elderly.

Background: Recent evidence supports the beneficial effect of alcohol on patients with traumatic brain injury (TBI). Pneumonia is a known complication following TBI; thus, the purpose of this study was to evaluate the effects of alcohol on pneumonia rates following moderate to severe TBI. Methods: From 2005 to 2009, the Los Angeles County Trauma Database was queried for all patients ≥14 y of age with isolated moderate to severe TBI and admission serum alcohol levels. The incidence of pneumonia was compared between TBI patients with and without a positive blood alcohol concentration (BAC) level. The study population was then stratified into four BAC levels: None (0 mg/dL), low (0–100 mg/dL), moderate (100–230 mg/dL), and high (≥230 mg/dL). Pneumonia rates were compared across these levels. Results: A total of 3547 patients with isolated, moderate to severe TBI were evaluated. Nearly 66% tested positive for alcohol. The pneumonia rate was significantly lower in the TBI patients who tested positive for alcohol (2.5%) compared with those who tested negative (4.0%, P = 0.017). The pneumonia rate also decreased across increasing BAC levels (linear trend P = 0.03). After logistic regression analysis, a positive ethanol (ETOH) level was associated with a reduced incidence of pneumonia (AOR = 0.62; 95%CI: 0.41–0.93; P = 0.020). Conclusion: A positive serum alcohol level was associated with a significantly lower pneumonia rate in isolated, moderate to severe TBI patients. This may explain the observed mortality reduction in TBI patients who test positive for alcohol. Additional research is warranted to investigate the potential therapeutic implications of this association. [ABSTRACT FROM AUTHOR]

Although recent evidence suggests a beneficial effect of alcohol for patients with traumatic brain injury (TBI), the level of alcohol that confers the protective effect is unknown. Our objective was to investigate the relationship between admission blood alcohol concentration (BAC) and out- comes in patients with isolated moderate to severe TBI. From 2005 to 2009, the Los Angeles County Trauma Database was queried for all patients ≥14 years of age with isolated moderate to severe TBI and admission serum alcohol levels. Patients were then stratified into four levels based on admission BAC: None (0 mg/dL), low (0-100 mg/dL), moderate (100-230 mg/dL), and high (->230 mg/dL). Demographics, patient characteristics, and outcomes were compared across levels. In evaluating 3794 patients, the mortality rate decreased with increasing BAC levels (linear trend P < 0.0001). In determining the relationship between BAC and mortality, multivariable logistic regression analysis demonstrated a high BAC level was significantly protective (adjusted odds ratio 0.55; 95% confidence interval: 0.38-0.8; P = 0.002). In the largest study to date, a high (≥230 mg/dL) admission BAC was independently associated with improved survival in patients with isolated moderate to severe TBI. Additional research is warranted to investigate the potential therapeutic implications. [ABSTRACT FROM AUTHOR]

The aim of this study was to assess how increasing age affects mortality in trauma patients with Glasgow Coma Scale (GCS) 3. The Los Angeles County Trauma System Database was queried for all patients aged 20 to 99 years admitted with GCS 3. Mortality was 41.8 per cent for the 3306 GCS 3 patients. Mortality in the youngest patients reviewed, those in the third decade, was 43.5 per cent. After logistic regression analysis, patients in the third decade had similar mortality rates to patients in the sixth (adjusted OR, 0.88; CI, 0.68 to 1.14; P = 0.33) and seventh decades (adjusted OR, 0.96; CI, 0.70 to 1.31; P = 0.79). A significantly lower mortality rate, however, was noted in the fifth decade (adjusted OR, 0.76; CI, 0.61 to 0.95; P = 0.02). Conversely, significantly higher mortality rates were noted in the eighth (adjusted OR, 1.93; CI, 1.38 to 2.71; P = 0.0001) and combined ninth/ tenth decades (adjusted OR, 2.47; CI, 1.71 to 3.57; P < 0.0001). Given the high survival in trauma patients with GCS 3 as well as continued improvement in survival compared with historical controls, aggressive care is indicated for patients who present to the emergency department with GCS 3.
