Road Traffic Related Injury Severity in Truck Drivers: A Prospective Medical and Technical Analysis of 582 Truck Crashes

Background: While cyclists and pedestrians are known to be at significant risk for severe injuries when exposed to road traffic accidents (RTA) involving trucks, little is known about RTA injury risk for truck drivers. Objectives: The aim of this study was to analyze the injury severity in truck drivers following RTAs. Patients and Methods: Our local accident research unit prospectively documented 43000 RTAs involving 582 trucks between 2000 and 2011. Injury severity, including the abbreviated injury scale (AIS) and the maximum abbreviated injury scale (MAIS) were analyzed. Technical parameters (e.g. delta-v, direction of impact), the location of accident, and its dependency on the road type were also taken into consideration. Results: Thirteen percent (77/582) of truck drivers were injured. Extremities were found to be at highest risk of injury with the lower extremities (36x) being injured most severely (10x: AIS 2 and 3). Death occurred only after collisions with other trucks, and severity of injuries increased with an increased speed limit. The maximum abbreviated injury scale was higher in the crash opponents (56x MAIS ≥ 3) compared to the truck drivers (8x MAIS ≥ 3). Overall, 82% of the crash opponents were injured. Conclusions: The safety of truck drivers is assured by their vehicles, the consequence being that the risk of becoming injured is likely to be low. However, the legs especially are at high risk for severe injuries during RTAs. This probability increases in the instance of a collision with another truck. Nevertheless, in RTAs involving trucks and regular passenger vehicles, the other party is in higher risk of injury

An Investigation into the Measurement of Workplace Injury Severity

Currently, the New Zealand Injury Information Manager, Statistics New Zealand, is scoping possible injury severity thresholds for workplace injury reporting purposes. Severity levels define which injuries to include within different reporting scenarios. This paper investigates methods of measuring workplace injury severity in Australia, the United Kingdom, Canada, the United States, and the widely-accepted quantitative approaches to injury severity levels, the ‘Abbreviated Injury Scale’ (AIS) and the ‘International Classification of Disease-Based Severity Score’ (ICISS), and discusses their application to Statistics New Zealand’s workplace injury reporting

Injury severity measures by AIS/90 manual and CAIS/85 chart in head injured patients

Estudo comparativo do uso do manual da ABBREVIATED INJURY SCALE (AIS) e dos mapas da CONDENSED ABBREVIATED INJURY SCALE (CAIS), como bases para cálculo do INJURY SEVERITY SCORE (ISS) em vítimas de trauma crânio-encefálico. Os resultados evidenciaram que o valor do ISS foi coincidente na maioria (59,51%) das vítimas passíveis de codificação pelos dois instrumentos. Quanto à indicação da faixa de gravidade do trauma (grave, moderado e leve) não existiram diferenças estatisticamente significantes entre os dois instrumentos. Quanto a capacidade de cobertura da CAIS/85 para a identificação da gravidade das lesões constatou-se que a CAIS/85 permitiu a pontuação de 61,38% das lesões pontuadas com a AIS/90.Estudio comparativo del uso del Manual de la ABBREVIATED INJURY SCALE (AIS) y de los mapas de la CONDENSED ABBREVIATED INJURY SCALE (CAIS), como base para el cálculo del INJURY SEVERITY SCORE (ISS) en víctimas de trauma cráneo-encefálico.

The results showed that the ISS value was equivalent in the majority of the patients (58,51%) codified by both scales. Also no statistic differences between the scales were perceived when we compared the severity levels as severe, moderate and minor. 61,38% of the lesions scored by AIS/90 were scored by CAIS/85, too

Apolipoprotein E epsilon 4 (APOE-ε4) genotype is associated with decreased 6-month verbal memory performance after mild traumatic brain injury

Introduction: The apolipoprotein E (APOE) ε4 allele associates with memory impairment in neurodegenerative diseases. Its association with memory after mild traumatic brain injury (mTBI) is unclear. Methods: mTBI patients (Glasgow Coma Scale score 13–15, no neurosurgical intervention, extracranial Abbreviated Injury Scale score ≤1) aged ≥18 years with APOE genotyping results were extracted from the Transforming Research and Clinical Knowledge in Traumatic Brain Injury Pilot (TRACK-TBI Pilot) study. Cohorts determined by APOE-ε4(+/−) were assessed for associations with 6-month verbal memory, measured by California Verbal Learning Test, Second Edition (CVLT-II) subscales: Immediate Recall Trials 1–5 (IRT), Short-Delay Free Recall (SDFR), Short-Delay Cued Recall (SDCR), Long-Delay F

Computational evidence for an early, amplified systemic inflammation program in polytrauma patients with severe extremity injuries

Extremity and soft tissue injuries contribute significantly to inflammation and adverse in-hospital outcomes for trauma survivors; accordingly, we examined the complex association between clinical outcomes inflammatory responses in this setting using in silico tools. Two stringently propensity-matched, moderately/severely injured (Injury Severity Score > 16) patient sub-cohorts of ~30 patients each were derived retrospectively from a cohort of 472 blunt trauma survivors and segregated based on their degree of extremity injury severity (above or below 3 on the Abbreviated Injury Scale). Serial blood samples were analyzed for 31 plasma inflammatory mediators. In addition to standard statistical analyses, Dynamic Network Analysis (DyNA) and Principal Component Analysis (PCA) were used to model systemic inflammation following trauma. Patients in the severe extremity injury sub-cohort experienced longer intensive care unit length of stay (LOS), total LOS, and days on a mechanical ventilator, with higher Marshall Multiple Organ Dysfunction (MOD) Scores over the first 7 days post-injury as compared to the mild/moderate extremity injury sub-cohort. The higher severity cohort had statistically significant elevated lactate, base deficit, and creatine phosphokinase on first blood draw, along with significant changes in multiple circulating inflammatory mediators. DyNA pointed to a sustained role for type 17 immunity in both sub-cohorts, along with IFN-γ in the severe extremity injury group. DyNA network complexity increased over 7 days post-injury in the severe injury group, while generally decreasing over this same time period in the mild/moderate injury group. PCA suggested a more robust activation of multiple pathways in the severe extremity injury group as compared to the mild/moderate injury group. These studies thus point to the possibility of self-sustaining inflammation following severe extremity injury vs. resolving inflammation following less severe extremity injury

Applicability of the abbreviated injury scale in forensic medical practice in Bulgaria

Introduction: The present study offers a detailed analysis of the principles of the American system for trauma classification AIS (Abbreviated Injury Scale) and  tests  the possibility of  its application  in  the field of forensic-medicine in Bulgaria, where currently traumas are classified according to the experts` subjective judgments.Materials and Methods: For the purposes of the study, expert reports have been used by 20 Bulgarian forensic doctors, written between 2009 and 2013, describing at least one temporarily life-threatening trauma. The severity of the traumas was evaluated according to AIS by the authors.Results: The comparison between the reports and the results of AIS indicates that the scale is applicable for forensic medical purposes and in determining life-threatening conditions. At the same time, differences have been discovered between the medico-biological qualifications of the Bulgarian experts regarding the same trauma; apparently as a result of the ambiguous wording of the Bulgarian Penal Code (unchanged since 1896).Conclusion: These differences accentuate the need for accepting a unified method of evaluating trauma severity. Taking such a step would dramatically improve the quality of Bulgarian forensic-medical reports

Trauma Early Mortality Prediction Tool (TEMPT) for assessing 28-day mortality.

Background:Prior mortality prediction models have incorporated severity of anatomic injury quantified by Abbreviated Injury Severity Score (AIS). Using a prospective cohort, a new score independent of AIS was developed using clinical and laboratory markers present on emergency department presentation to predict 28-day mortality. Methods:All patients (n=1427) enrolled in an ongoing prospective cohort study were included. Demographic, laboratory, and clinical data were recorded on admission. True random number generator technique divided the cohort into derivation (n=707) and validation groups (n=720). Using Youden indices, threshold values were selected for each potential predictor in the derivation cohort. Logistic regression was used to identify independent predictors. Significant variables were equally weighted to create a new mortality prediction score, the Trauma Early Mortality Prediction Tool (TEMPT) score. Area under the curve (AUC) was tested in the validation group. Pairwise comparison of Trauma Injury Severity Score (TRISS), Revised Trauma Score, Glasgow Coma Scale, and Injury Severity Score were tested against the TEMPT score. Results:There was no difference between baseline characteristics between derivation and validation groups. In multiple logistic regression, a model with presence of traumatic brain injury, increased age, elevated systolic blood pressure, decreased base excess, prolonged partial thromboplastin time, increased international normalized ratio (INR), and decreased temperature accurately predicted mortality at 28 days (AUC 0.93, 95% CI 0.90 to 0.96, P&lt;0.001). In the validation cohort, this score, termed TEMPT, predicted 28-day mortality with an AUC 0.94 (95% CI 0.92 to 0.97). The TEMPT score preformed similarly to the revised TRISS score for severely injured patients and was highly predictive in those having mild to moderate injury. Discussion:TEMPT is a simple AIS-independent mortality prediction tool applicable very early following injury. TEMPT provides an AIS-independent score that could be used for early identification of those at risk of doing poorly following even minor injury. Level of evidence:Level II
