Purpose: Optimal ankle dorsiflexion range of motion plays a vital role in attaining the essential crouched posture necessary for excelling in speed skating. The purpose of this study was to determine how the ankle dorsiflexion angle evolves throughout a day of training and to identify the factors that influence this angle. Methods: Thirty short-track speed skaters, from 2 teams, participated in this study. The maximum ankle dorsiflexion angle was obtained in a lunge position facing a wall, using a digital inclinometer. All measures were obtained 3 times per side, 6 times per day, on 2 training days separated by at least a week. We conducted multiple tests to study the impact of repetition, day, side, team level, sex, and moment on the ankle dorsiflexion angle. Results: The 3 times repeated measures and the 2 days of training did not have a significant influence on the results. There was a statistically significant difference between the first time point of the day and the 5 other time points for both ankles. Moreover, the influence of sex and team level was not statistically significant. Conclusions: The results indicate that there are significant changes in ankle dorsiflexion range of motion but only after the first warm-up of the day. Such findings could enable team staff to enhance athletes' precompetition preparation and tailor ankle mobility training regimens more effectively. [ABSTRACT FROM AUTHOR]

The article focuses on evaluating the effectiveness of a provincial prehospital trauma triage protocol (EQTPT) in identifying patients needing urgent trauma care, assessing its sensitivity and specificity in a regional context. Topics include the protocol's performance in distinguishing between different levels of trauma severity based on patient outcomes and the implications for improving prehospital triage practices to enhance timely.

Background: Multiple clinical practice guidelines recommend minimizing radiation in trauma patients but there is a knowledge gap on the importance of this problem for trauma transfers. We aimed to estimate the incidence of pretransfer and repeat posttransfer computed tomography (CT) overall and in patients with an indication for immediate transfer, to assess interhospital practice variation, to identify predictors, and to quantify the influence of pretransfer CT on time to transfer. Methods We conducted a retrospective multicenter cohort study on patients transferred to major trauma centers from 2013 to 2019. Multilevel generalized linear regression was used to generate intraclass correlation coefficients (ICCs) to assess interhospital variation, multilevel logistic regression to generate odds ratios for each predictor, and geometric mean ratios to quantify the influence of CT on time to transfer. Results Of 18,244 patients included, 8501 (47%) had a pretransfer CT and one‐quarter (26%) had a repeat posttransfer CT. Interhospital variation was moderate for pretransfer CT (5%–66%, ICC 12.5%) and for repeat posttransfer CT (7%–44%, ICC 14.7%). Pretransfer imaging was more frequent in elders and in males and repeat posttransfer imaging decreased over the study period but was more frequent in patients transferred in from Level III/IV centers than nondesignated hospitals. Time to transfer was doubled in patients who had a pretransfer CT. Conclusions: Results suggest that pretransfer CT and repeat posttransfer CT are frequent and are subject to significant practice variation. In addition, pretransfer CT is associated with increased times to transfer though additional studies are needed to demonstrate causation. These results highlight potential opportunities to reduce low‐value imaging for trauma transfers. [ABSTRACT FROM AUTHOR]

Summary: The Standardized Trauma and Resuscitation Team Training (S.T.A.R.T.T.) course focuses on training multidisciplinary trauma teams: surgeons/physicians, registered nurses (RNs), respiratory therapists (RTs) and, most recently, prehospital personnel. The S.T.A.R.T.T. curriculum highlights crisis management (CRM) skills: communication, teamwork, leadership, situational awareness and resource utilization. This commentary outlines the modifications made to the course curriculum in order to satisfy the learning needs of a bilingual audience. The results suggest that bilingual multidisciplinary CRM courses are feasible, are associated with high participant satisfaction and have no clear detriments. [ABSTRACT FROM AUTHOR]

Background: Variations in adjusted costs have been observed among trauma centres in the United States but patient outcomes were not better in centres with higher costs. Attempts to improve injury care efficiency are hampered by insufficient patient-level information on resource use and on the drivers of resource use intensity.Objectives: To estimate patient-level resource use for injury admissions, identify determinants of resource use intensity, and evaluate inter-hospital variations in resource use.Methods: We conducted a retrospective cohort study including ≥16-year-olds admitted to adult trauma centres in a mature, inclusive Canadian trauma system between 2014 and 2016. We extracted data from the trauma registry and hospital financial reports. We estimated resource use with activity-based costs, identified determinants of resource use intensity using a multilevel linear model and assessed the relative importance of each determinant with Cohen's f2. We evaluated inter-provider variations with intraclass correlation coefficients (ICC) and 95% confidence intervals.Results: We included 32,411 patients. Median costs per admission were $4857 (Quartiles 1 and 3 2961-8448). The most important contributors to total resource use were the medical ward (57%), followed by the operating room (OR; 23%) and the intensive care unit (13%). The strongest determinant of resource use intensity was discharge destination (Cohen's f2 = 7%). The most resource intense patient group was spinal cord injuries with $11,193 (7115-17,606) per admission. While resource use increased with increasing age for the medical ward, it decreased with increasing age for the OR. Resource use was 18% higher in level I centres compared to level IV centres and we observed significant variations in resource use across centres (ICC = 5% [4-6]), particularly for the OR (28% [20-40]).Conclusions: Resource use for acute injury care in Quebec is not solely due to the clinical status of patients. We identified determinants of resource use that can be used to establish evidence-based resource allocations and improve injury care efficiency. The method we developed for estimating patient-level, in-hospital resource use for injury admissions and identifying related determinants could be reproduced using local trauma registry data and our unit costs or unit costs specific to each setting.

Purpose: Approximately, one out of five patients hospitalized following injury will develop at least one hospital complication, more than three times that observed for general admissions. We currently lack actionable Quality Indicators (QI) targeting specific complications in this population. We aimed to derive and validate QI targeting hospital complications for injury admissions and develop algorithms to identify patient charts to review., Methods: We conducted a retrospective cohort study including patients with major trauma admitted to any level I or II adult trauma center an integrated Canadian trauma system (2014-2019). We used the trauma registry to develop five QI targeting deep vein thrombosis/pulmonary embolism (DVT/PE), decubitus ulcers, delirium, pneumonia and urinary tract infection (UTI). We developed algorithms to identify patient charts to revise on consultation with a group of clinical experts., Results: The study population included 14,592 patients of whom 5.3% developed DVT or PE, 2.7% developed a decubitus ulcer, 8.6% developed delirium, 14.7% developed pneumonia and 7.3% developed UTI. The indicators demonstrated excellent predictive performance (Area Under the Curve 0.81-0.87). We identified 4 hospitals with a higher than average incidence of at least one of the targeted complications. The algorithms identified on average 50 and 20 charts to be reviewed per year for level I and II centers, respectively., Conclusion: In line with initiatives to improve the quality of trauma care, we propose QI targeting reductions in hospital complications for injury admissions and algorithms to generate case lists to facilitate the review of patient charts., (© 2021.

Background: Guidelines for injury care are increasingly moving away from surgical management towards less invasive procedures but there is a knowledge gap on how these recommendations are influencing practice. We aimed to assess inter-hospital variation in surgical intensity for injury admissions and evaluate the correlation between hospital surgical intensity and mortality/complications., Methods: We included adults admitted for major trauma between 2006 and 2016 in a Canadian provincial trauma system. Analyses were stratified for orthopaedic (n = 16 887), neurological (n = 12 888) and torso injuries (n = 9816). Surgical intensity was quantified with the number of surgical procedures <72 hours. Inter-hospital variation was assessed with the intra-class correlation coefficient (ICC). We assessed the correlation between the risk-adjusted mean number of surgical procedures and risk-adjusted incidence of mortality and complications using Pearson correlation coefficients (r)., Results: Moderate inter-hospital variation was observed for orthopaedic surgery (ICC = 14.0%) whereas variation was low for torso surgery (ICC = 2.7%) and neurosurgery (ICC = 0.8%). Surgical intensity was negatively correlated with hospital mortality for torso injury (r = -.32, P = .02) and neurotrauma (r = -.65, P = .08). A strong positive correlation was observed with hospital complications for orthopaedic injuries (r = .36, P = .006) whereas the opposite was observed for neurotrauma (r = -.71, P = .05)., Conclusions: Results should be interpreted with caution as they may be a result of residual confounding. However, they may suggest that there are opportunities for quality improvement in surgical care for injury admissions, particularly for orthopaedic injuries. Moving forward, we should aim to prospectively evaluate adherence to guidelines on non-operative management and their impact on mortality and morbidity., (© 2020 John Wiley & Sons Ltd.)

Importance: The rate of complications among injury admissions has been estimated to be more than 3 times that observed for general admissions, and complications have been targeted as an important quality-of-care metric. Despite the negative effect of complications on resource use and patient mortality and morbidity, there is no standardized method to benchmark trauma centers in terms of in-hospital complications, to our knowledge., Objectives: To develop a quality indicator (QI) for in-hospital complications that can be used to evaluate the quality of acute injury care and to assess its validity., Design, Setting, and Participants: Multicenter retrospective cohort study. The setting was a well-established inclusive trauma system in Canada. Participants included all 66 048 moderate or major injury admissions to an adult trauma center between April 1, 2006, and March 31, 2012. The dates of the analysis were January to April 2015., Main Outcomes and Measures: The primary outcome was the occurrence of at least 1 in-hospital complication. We selected risk-adjustment variables by expert consultation and bootstrap resampling. We evaluated internal validity using measures of discrimination, construct validity, and forecasting., Results: The study cohort comprised 66 048 patients. Their mean (SD) age was 59 (22) years, and 48.0% were female. Fifteen percent of patients had at least 1 in-hospital complication. The risk-adjustment model has excellent discrimination (area under the curve, 0.81) and calibration. The QI was correlated with the risk-adjusted incidence of mortality (r = 0.71), unplanned readmission (r = 0.43), and mean length of stay (r = 0.68). Hospital performance on the QI from 2007 to 2009 was predictive of performance from 2010 to 2012 (r = 0.82)., Conclusions and Relevance: We developed a QI to benchmark trauma centers on in-hospital complications among injury admissions. The QI is based on data that are routinely collected in most trauma systems and demonstrates good internal validity. The integration of this QI in trauma quality improvement programs will facilitate the identification of quality problems, the implementation of solutions, and the evaluation of their effectiveness. Therefore, the QI has the potential to lead to reductions in mortality, morbidity, and resource use after injury.
