AbstractObjectivesEvidence-based guidelines regarding the optimal mode of transport for trauma patients from scene to trauma centre are lacking. The purpose of this study was to investigate the relationship between trauma patient outcomes and mode of transport at a single Ontario Level I Trauma Centre, and specifically to investigate if the mode of transport confers a mortality benefit.MethodsA historical, observational cohort study was undertaken to compare rotor-wing and ground transported patients. Captured data included demographics, injury severity, temporal and mortality variables. TRISS-L analysis was performed to examine mortality outcomes.Results387 rotor-wing transport and 2,759 ground transport patients were analyzed over an 18-year period. Rotor-wing patients were younger, had a higher Injury Severity Score, and had longer prehospital transport times. Mechanism of injury was similarly distributed between groups. After controlling for heterogeneity with TRISS-L analysis, the mortality of rotor-wing patients was found to be lower than predicted mortality, whereas the converse was found with ground patients.ConclusionRotor-wing and ground transported trauma patients represent heterogeneous populations. Accounting for these differences, rotor-wing patients were found to outperform their predicted mortality, whereas ground patients underperformed predictions.

Introductio: Although management of severely injured patients in the Trauma Resuscitation Unit (TRU) follows evidence-based guidelines, algorithms for treatment of the slightly injured are limited. Methods: All trauma patients in a period of eight months in a Level I trauma center were followed. Retrospective analysis was performed only in patients ≥18 years with primary TRU admission, Abbreviated Injury Scale (AIS) ≤ 1, Maximum Abbreviated Injury Scale (MAIS) ≤ 1 and Injury Severity Score (ISS) ≤3 after treatment completion and ≥24 h monitoring in the units. Cochran’s Q-test was used for the statistical evaluation of AIS and ISS changes in units. Results: One hundred and twelve patients were enrolled in the study. Twenty-one patients (18.75%) reported new complaints after treatment completion in the TRU. AIS rose from the Intermediate Care Unit (IMC) to Normal Care Unit (NCU) 6.2% and ISS 6.9%. MAIS did not increase >2, and no intervention was necessary for any patient. No correlation was found between computed tomography (CT) diagnostics in TRU and AIS change. Conclusions: The data suggest that AIS, MAIS and ISS did not increase significantly in patients without a severe injury during inpatient treatment, regardless of the type of CT diagnostics performed in the TRU, suggesting that monitoring of these patients may be unnecessary.

AbstractObjectivesTo determine if changes to the Ontario Highway Traffic Act (OHTA) in 2009 and 2010 had an effect on the proportion of alcohol-related motor vehicle collisions (MVCs) presenting to a trauma centre over a 10-year period.MethodsA retrospective review of the trauma registry at a Level I trauma centre in southwestern Ontario was undertaken. The trauma registry is a database of all trauma patients with an injury severity score (ISS) ≥12 and/or who had trauma team activation. Descriptive statistics were calculated. Interrupted time series analyses with ARIMA modeling were performed on quarterly data from 2004-2013.ResultsA total of 377 drivers with a detectable serum ethanol concentration (SEC) were treated at our trauma centre over the 10-year period, representing 21% of all MVCs. The majority (330; 88%) were male. The median age was 31 years, median SEC was 35.3 mmol/L, and median ISS was 21. A total of 29 (7.7%) drinking drivers died from their injuries after arriving to hospital. There was no change in the proportion of drinking drivers after the 2009 amendment, but there was a significant decline in the average SEC of drinking drivers after changes to the law. There was no difference in the proportion of drinking drivers ≤21 years after introduction of the 2010 amendment for young and novice drivers.ConclusionsThere was a significance decline in the average SEC of all drinking drivers after the 2009 OHTA amendment, suggesting that legislative amendments may have an impact on drinking before driving behaviour.

AbstractBackgroundAfter parasuicide there is a high risk of reattempts. However, it seems that patients who survived severe suicidal trauma recover well. Therefore, the outcome of patients with severe multiple blunt trauma as a result of a suicide attempt was investigated with respect to psychiatric and somatic health, quality of life (QOL) and suicide reattempt rates.MethodsPatients who underwent a suicide attempt were isolated from a prospectively collected sample of trauma patients from a level I University Trauma Centre. Follow-up examination was performed 6.1 ± 3 years after the trauma. A physical and psychiatric examination was performed, using established psychiatric scales.ResultsTwelve percent of severely injured patients were identified as suicide attempters (male/female: 37/28, mean age 38 ± 18 years, mean Injury Severity Score (ISS) 40 ± 15 points). A psychiatric diagnosis was present in 90% at the time of the suicide attempt. Twenty-one patients died during the hospital stay (32%) and six subjects died thereafter, none due to suicide. Thirty-five individuals were eligible for examination. None of them had reattempted suicide. Seventeen (48%) had good outcomes reflected by absent or ambulatory psychiatric treatment, employment, normal psychiatric findings and good psychosocial ability. An indeterminate outcome was determined in 24%. Predictive variables for an adverse outcome (10 patients, 28%) were found to be a diagnosis of schizophrenia, continued psychiatric treatment and being without employment.ConclusionsDespite the seriousness of the suicide attempt, survivors recovered well in about half the cases with no further suicide attempt in any patient. An early psychiatric consultation already on the Intensive Care Unit (ICU) is recommended.

Abstract Purpose Rotational thromboelastometry (ROTEM®) allows guided blood product resuscitation to correct trauma induced coagulopathy in bleeding trauma patients. FIBTEM amplitude at 10 minutes (A10) has been widely used to identify hypofibrinogenaemia; locally a threshold of < 11 mm has guided fibrinogen replacement. Amplitude at 5 minutes (A5) carries an inherent time advantage. The primary aim was to explore the relationship between FIBTEM A5 and A10 in a trauma. Secondary aim was to investigate the use of A5 as a surrogate for A10 within a fibrinogen-replacement algorithm.Methods Retrospective observational cohort study of arrival ROTEM results from 1539 consecutive trauma patients at a Level 1 trauma centre in Australia. Consistency of agreement between FIBTEM A5 and A10 was assessed. A new fibrinogen replacement threshold was developed for A5 using the A5 – A10 bias; this was clinically compared to the existing A10 threshold.Results FIBTEM A5 displayed excellent consistency of agreement with A10. Intraclass correlation coefficient = 0.972 (95% confidence interval [CI] 0.969 – 0.974). Bias of A5 to A10 was -1.49 (95% CI 1.43 -1.56) mm. 19.34% patients met the original local threshold of A10 < 11 mm; 19.28% patients met the new, bias-adjusted threshold of A5 < 10 mm.Conclusions ROTEM FIBTEM A5 reliably predicts A10 in trauma. This further validates use of the A5 result over A10 allowing faster decision-making in time-critical resuscitation of trauma patients. A modification of -1 to the A10 threshold might be appropriate for use with the A5 value in trauma patients.

Score Inflation

Introduction Extensive research relying on Injury Severity Scores (ISS) reports a mortality benefit from routine non-selective thoracic CTs (an integral part of pan-computed tomography (pan-CT)s). Recent research suggests this mortality benefit may be artifact. We hypothesized that the use of pan-CTs inflates ISS categorization in patients, artificially affecting admission rates and apparent mortality benefit. Methods Eight hundred and eleven patients were identified with an ISS >15 with significant findings in the chest area. Patient charts were reviewed and scores were adjusted to exclude only occult injuries that did not affect treatment plan. Pearson chi-square tests and multivariable logistic regression were used to compare adjusted cases vs non-adjusted cases. Results After adjusting for inflation, 388 (47.8%) patients remained in the same ISS category, 378 (46.6%) were reclassified into 1 lower ISS category, and 45 (5.6%) patients were reclassified into 2 lower ISS categories. Patients reclassified by 1 category had a lower rate of mortality ( P < 0.001), lower median total hospital LOS ( P < .001), ICU days ( P < .001), and ventilator days ( P = 0.008), compared to those that remained in the same ISS category. Conclusion Injury Severity Score inflation artificially increases survival rate, perpetuating the increased use of pan-CTs. This artifact has been propagated by outdated mortality prediction calculation methods. Thus, prospective evaluations of algorithms for more selective CT scanning are warranted.

ABSTRACTObjective: Trauma casualties caused by terror-related events and children injured as a result of trauma may be given preference in hospital emergency departments (EDs) due to their perceived importance. We investigated whether there are differences in the treatment and hospitalization of terror-related casualties compared to other types of injury events and between children and adults injured in terror-related events.Methods: Retrospective study of 121 608 trauma patients from the Israel Trauma Registry during the period of October 2000-December 2005. Of the 10 hospitals included in the registry, 6 were level I trauma centers and 4 were regional trauma centers. Patients who were hospitalized or died in the ED or were transferred between hospitals were included in the registry.Results: All analyses were controlled for Injury Severity Score (ISS). All patients with ISS 1-24 terror casualties had the highest frequency of intensive care unit (ICU) admissions when compared with patients after road traffic accidents (RTA) and other trauma. Among patients with terror-related casualties, children were admitted to ICU disproportionally to the severity of their injury. Logistic regression adjusted for injury severity and trauma type showed that both terror casualties and children have a higher probability of being admitted to the ICU.Conclusions: Injured children are admitted to ICU more often than other age groups. Also, terror-related casualties are more frequently admitted to the ICU compared to those from other types of injury events. These differences were not directly related to a higher proportion of severe injuries among the preferred groups.(Disaster Med Public Health Preparedness. 2012;6:14–19)

Abstract Introduction Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a less invasive alternative to resuscitative thoracotomy (RT) for life threatening, infra-diaphragmatic, non-compressible hemorrhage from trauma. Existing evidence surrounding the efficacy of REBOA is conflicting; nevertheless, expert consensus suggests that REBOA should be considered in select trauma patients. There has been a paucity of studies that evaluate the potential utility of REBOA in the Canadian setting. The study objective was to evaluate the percentage of trauma patients presenting to a Level 1 Canadian trauma centre that would have met criteria for REBOA. Methods We conducted a retrospective chart review of patients recorded in the British Columbia Trauma Registry who warranted a trauma team activation (TTA) at our institution. We identified REBOA candidates using pre-defined criteria based on published guidelines. Each TTA case was screened by a reviewer, and then each Potential Candidate was reviewed by a panel of trauma physicians for determination of final candidacy. Results Fourteen patients were classified as Likely REBOA Candidates (2.2% of TTAs, median age 46.1 years, 64.3% female). These patients had a median Injury Severity Score of 31.5 (IQR 26.8). The main sources of hemorrhage in these patients were from abdominal injuries (71.4%) and pelvic fractures (42.9%). Conclusion The percentage of patients who met criteria for REBOA is similar to that of RTs performed at our Canadian institution. While REBOA would be performed infrequently, it is a less-invasive alternative to RT, which could be a potentially life-saving procedure in a small group of the most severely injured trauma patients.

Divergent injury patterns may indicate the need for differing strategies in combat and civilian trauma patients. This study aims to compare outcomes of colon injury management in these two populations. Parallel retrospective reviews were conducted comparing warfighters (n = 59) injured downrange and subsequently transferred to the United States with civilians (n = 30) treated at a United States Level I trauma center. Patient characteristics, mechanisms of injury, treatment course, and complications were compared. The civilian (CP) and military (MP) populations did not differ in Injury Severity Score (MP 20 vs CP 26; P = 0.41). The MP experienced primarily blast injuries (51%) as opposed to blunt trauma (70%; P < 0.01) in the CP. The site of colon injury did not differ between groups ( P = 0.15). Initial management was via primary repair (53%) and resection and anastomosis (27%) in the CP versus colostomy creation (47%) and stapled ends (32%) in the MP ( P < 0.001). Ultimately, the CP and MP experienced equivalent continuity rates (90%). Overall complications (MP 68% vs CP 53%; P = 0.18) and mortality (MP 3% vs CP 3%; P = 0.99) did not differ between the two groups. The CP and MP experience different mechanisms and initial management of colon injury. Ultimately, continuity is restored in the majority of both populations.

In the past, autopsy served as the gold standard to document diagnostic accuracy. Although a valuable contributor to medical education, information collected from autopsies is frequently delayed and poorly used. The purpose of this study was to determine the degree of concordance between clinical findings and autopsy results of trauma patients involved in fatal vehicular-related crashes. A 10-year retrospective review of trauma patients involved in fatal vehicular-related crashes who subsequently had an autopsy performed was conducted at an American College of Surgeons-verified Level I trauma center. The clinical record, trauma registry data, and autopsy results were reviewed. Degree of concordance was evaluated using the Goldman Type Errors Criteria. A total of 207 decedents were included (mean age, 41; 63% male; median Glascow Coma Scale score, 3; median Injury Severity Score, 37). The majority (69.6%) of decedents were injured in motor vehicle crashes. Total treatment time was <15 minutes in 29.0 per cent of cases, <6 hours in 59.4 per cent of cases, and <24 hours in 73.9 per cent of cases. Location of death was the emergency department (43.0%), the intensive care unit (49.8%), the operating room (5.4%), and the nursing floor (1.0%). There were no Goldman Class I or IV type errors, (i.e., no major or minor discrepancies, respectively, that may have altered therapy or survival of the patient). Following ATLS-based protocols results in appropriate identification of clinically significant injuries in patients involved in motor vehicular-related crashes. The routine use of autopsy results offers little additional information to a mature American College of Surgeons-verified Level I trauma program.
