Cirrhosis in trauma patients is an indicator of poor prognosis, but current trauma injury grading systems do not take into account liver dysfunction as a risk factor. Our objective was to construct a simple clinical mortality prediction model in cirrhotic trauma patients: Cirrhosis Outcomes Score in Trauma (COST). ⋯ Current trauma injury grading systems do not take into account liver dysfunction as a risk factor. COST is highly predictive of mortality in cirrhotic trauma patients. The simplicity of the score makes it useful in guiding clinical care and in optimizing goals of care discussions. Future studies to validate this prediction model are required prior to clinical use.

Diagnostic Criteria Study BACKGROUND: The morbidity and mortality associated with ischemic stroke attributable to blunt cerebrovascular injury (BCVI) warrant aggressive screening. The Denver Criteria (DC) and Expanded Denver Criteria (eDC) have imprecise elements that can be difficult and subjective in application and can delay or prevent screening. We hypothesize these screening criteria lack adequate ability to consistently identify BCVI and that the use of a liberalized screening approach with CT angiography (CTA) is superior without increasing risk of acute kidney injury (AKI). ⋯ BCVI would be missed over 30% of the time using the DC and eDC compared to liberalized use of screening CTA. Risk of AKI due to CTA did not occur at a clinically meaningful level, supporting liberal CTA screening.

Penetrating cardiac injuries (PCI) are often fatal despite rapid transport and treatment in the prehospital setting. Although many studies have identified risk factors for mortality, few studies have included non-transported field mortalities. This study analyzes penetrating cardiac injuries including hospital and coroner reports in the current era. ⋯ Survival to both TC evaluation and hospital discharge following PCI is influenced by many factors including age, mechanism, anatomic site, and grade. Despite advances in trauma care, survival has not appreciably improved.

Systematic reviews, of level-I primary literature, are the gold standard for the formation of Clinical Practice Guidelines in Orthopaedic Surgery. When systematic reviews have multiple groups of data, meta-analyses can be conducted to analyse the direct comparison of the data points (pairwise meta-analysis). Over recent years, statisticians have created a new statistical model called network meta-analyses that can be applied to systematic reviews. network meta-analyses allow for comparison of different treatment outcomes that may or may not have been directly assessed through level-I primary studies. network meta-analyses are appearing more and more in Orthopaedic Surgery literature; therefore, in this article, we discuss what a Network Meta-analysis is and its application in Orthopaedics.

Observational Study
Clinical characteristics of patients with snow sports trauma transported to a trauma care center: A retrospective observational study.
Snow sports are a popular recreational activity; however, the incidence of injury of snow sports can be high for skiers and snowboarders. Our hospital receives severe trauma cases from snow resorts and hospitals throughout the region. This study aimed to determine whether the risk of snow sports-related major trauma that requires emergency surgery under general anesthesia varies by the equipment and injury mechanism. ⋯ Snowboard as equipment and falls after jumping as a mechanism of injury tended to be associated with emergency surgery under general anesthesia, with no significant differences. In order to provide adequate resources for snow sports trauma, the cause of the patient's injury is strongly related to the urgency of the condition, and transport to a trauma center should be actively considered. Further studies are warranted with respect to the effects of personal protective equipment and skill level.
