RESUMO
STUDY OBJECTIVE: Our primary objectives were to identify clinical practice guideline recommendations for children with acute mild traumatic brain injury (mTBI) presenting to an emergency department (ED), appraise their overall quality, and synthesize the quality of evidence and the strength of included recommendations. METHODS: We searched MEDLINE, EMBASE, Cochrane Central, Web of Science, and medical association websites from January 2012 to May 2023 for clinical practice guidelines with at least 1 recommendation targeting pediatric mTBI populations presenting to the ED within 48 hours of injury for any diagnostic or therapeutic intervention in the acute phase of care (ED and inhospital). Pairs of reviewers independently assessed overall clinical practice guideline quality using the Appraisal of Guidelines Research and Evaluation (AGREE) II tool. The quality of evidence on recommendations was synthesized using a matrix based on the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) Evidence-to-Decision framework. RESULTS: We included 11 clinical practice guidelines, of which 6 (55%) were rated high quality. These included 101 recommendations, of which 34 (34%) were based on moderate- to high-quality evidence, covering initial assessment, initial diagnostic imaging, monitoring/observation, therapeutic interventions, discharge advice, follow-up, and patient and family support. We did not identify any evidence-based recommendations in high-quality clinical practice guidelines for repeat imaging, neurosurgical consultation, or hospital admission. Lack of strategies and tools to aid implementation and editorial independence were the most common methodological weaknesses. CONCLUSIONS: We identified 34 recommendations based on moderate- to high-quality evidence that may be considered for implementation in clinical settings. Our review highlights important areas for future research. This review also underlines the importance of providing strategies to facilitate the implementation of clinical practice guideline recommendations for pediatric mTBI.

OBJECTIVE: To systematically review clinical practice guidelines (CPGs) for pediatric multisystem trauma, appraise their quality, synthesize the strength of recommendations and quality of evidence, and identify knowledge gaps. BACKGROUND: Traumatic injuries are the leading cause of death and disability in children, who require a specific approach to injury care. Difficulties integrating CPG recommendations may cause observed practice and outcome variation in pediatric trauma care. METHODS: We conducted a systematic review using Medline, Embase, Cochrane Library, Web of Science, ClinicalTrials, and grey literature, from January 2007 to November 2022. We included CPGs targeting pediatric multisystem trauma with recommendations on any acute care diagnostic or therapeutic interventions. Pairs of reviewers independently screened articles, extracted data, and evaluated the quality of CPGs using "Appraisal of Guidelines, Research, and Evaluation II." RESULTS: We reviewed 19 CPGs, and 11 were considered high quality. Lack of stakeholder engagement and implementation strategies were weaknesses in guideline development. We extracted 64 recommendations: 6 (9%) on trauma readiness and patient transfer, 24 (38%) on resuscitation, 22 (34%) on diagnostic imaging, 3 (5%) on pain management, 6 (9%) on ongoing inpatient care, and 3 (5%) on patient and family support. Forty-two (66%) recommendations were strong or moderate, but only 5 (8%) were based on high-quality evidence. We did not identify recommendations on trauma survey assessment, spinal motion restriction, inpatient rehabilitation, mental health management, or discharge planning. CONCLUSIONS: We identified 5 recommendations for pediatric multisystem trauma with high-quality evidence. Organizations could improve CPGs by engaging all relevant stakeholders and considering barriers to implementation. There is a need for robust pediatric trauma research, to support recommendations.

PURPOSE: Most North American trauma systems have designated trauma centres (TCs) including level I (ultraspecialized high-volume metropolitan centres), level II (specialized medium-volume urban centres), and/or level III (semirural or rural centres). Trauma system configuration varies across provinces and it is unclear how these differences influence patient distributions and outcomes. We aimed to compare patient case mix, case volumes, and risk-adjusted outcomes of adults with major trauma admitted to designated level I, II, and III TCs across Canadian trauma systems. METHODS: In a national historical cohort study, we extracted data from Canadian provincial trauma registries on major trauma patients treated between 2013 and 2018 in all designated level I, II, or III TCs in British Columbia, Alberta, Quebec, and Nova Scotia; level I and II TCs in New Brunswick; and four TCs in Ontario. We used multilevel generalized linear models to compare mortality and intensive care unit (ICU) admission and competitive risk models for hospital and ICU length of stay (LOS). Ontario could not be included in outcome comparisons because there were no population-based data from this province. RESULTS: The study sample comprised 50,959 patients. Patient distributions in level I and II TCs were similar across provinces but we observed significant differences in case mix and volumes for level III TCs. There was low variation in risk-adjusted mortality and LOS across provinces and TCs but interprovincial and intercentre variation in risk-adjusted ICU admission was high. CONCLUSIONS: Our results suggest that differences in the functional role of TCs according to their designation level across provinces leads to significant variations in the distribution of patients, case volumes, resource use, and clinical outcomes. These results highlight opportunities to improve Canadian trauma care and underline the need for standardized population-based injury data to support national quality improvement efforts.
RéSUMé: OBJECTIF: La plupart des systèmes de traumatologie nord-américains disposent de centres de traumatologie (CT) désignés, y compris de niveau I (centres métropolitains ultraspécialisés à volume élevé), de niveau II (centres urbains spécialisés à volume moyen) et/ou de niveau III (centres semi-ruraux ou ruraux). La configuration des systèmes de traumatologie varie d'une province à l'autre et nous ne savons pas comment ces différences influent sur la répartition de la patientèle et sur les issues. Notre objectif était de comparer le mélange de cas des patient·es, le volume de cas et les issues ajustées en fonction du risque des adultes ayant subi un traumatisme majeur admis·es dans des CT désignés de niveaux I, II et III dans l'ensemble des systèmes de traumatologie canadiens. MéTHODE: Dans une étude de cohorte historique nationale, nous avons extrait des données des registres provinciaux canadiens de traumatologie sur les patient·es ayant subi un traumatisme majeur traité·es entre 2013 et 2018 dans tous les CT désignés de niveau I, II ou III en Colombie-Britannique, en Alberta, au Québec et en Nouvelle-Écosse, les CT de niveau I et II au Nouveau-Brunswick, et dans quatre CT en Ontario. Nous avons utilisé des modèles linéaires généralisés à plusieurs niveaux pour comparer la mortalité, les admissions en unité de soins intensifs (USI) et les modèles de risque compétitif pour la durée du séjour à l'hôpital et à l'USI. L'Ontario n'a pas pu être inclus dans les comparaisons des devenirs parce qu'il n'y avait pas de données démographiques pour cette province. RéSULTATS: L'échantillon de l'étude comptait 50 959 patient·es. La répartition des patient·es dans les CT de niveaux I et II était similaire d'une province à l'autre, mais nous avons observé des différences significatives dans le mélange des cas et les volumes pour les CT de niveau III. Il y avait une faible variation de la mortalité ajustée en fonction du risque et des durées de séjour entre les provinces et les CT, mais la variation interprovinciale et intercentre des admissions à l'USI ajustées en fonction du risque était élevée. CONCLUSION: Nos résultats suggèrent que les différences dans le rôle fonctionnel des CT selon leur niveau de désignation d'une province à l'autre entraînent des variations importantes dans la répartition des patient·es, le nombre de cas, l'utilisation des ressources et les issues cliniques. Ces résultats mettent en évidence les possibilités d'amélioration des soins de traumatologie au Canada et soulignent la nécessité de disposer de données normalisées sur les blessures dans la population pour appuyer les efforts nationaux d'amélioration de la qualité.

BACKGROUND: Lack of adherence to recommendations on pediatric orthopaedic injury care may be driven by lack of knowledge of clinical practice guidelines (CPGs), heterogeneity in recommendations or concerns about their quality. We aimed to identify CPGs for pediatric orthopaedic injury care, appraise their quality, and synthesize the quality of evidence and the strength of associated recommendations. METHODS: We searched Medline, Embase, Cochrane CENTRAL, Web of Science and websites of clinical organizations. CPGs including at least one recommendation targeting pediatric orthopaedic injury populations on any diagnostic or therapeutic intervention developed in the last 15 years were eligible. Pairs of reviewers independently extracted data and evaluated CPG quality using the Appraisal of Guidelines Research and Evaluation (AGREE) II tool. We synthesized recommendations from high-quality CPGs using a recommendations matrix based on the GRADE Evidence-to-Decision framework. RESULTS: We included 13 eligible CPGs, of which 7 were rated high quality. Lack of stakeholder involvement and applicability (i.e., implementation strategies) were identified as weaknesses. We extracted 53 recommendations of which 19 were based on moderate or high-quality evidence. CONCLUSIONS: We provide a synthesis of recommendations from high-quality CPGs that can be used by clinicians to guide treatment decisions. Future CPGs should aim to use a partnership approach with all key stakeholders and provide strategies to facilitate implementation. This study also highlights the need for more rigorous research on pediatric orthopaedic trauma. LEVEL OF EVIDENCE: Level II-therapeutic study.
RESUMO
BACKGROUND: Comparisons across trauma systems are key to identifying opportunities to improve trauma care. We aimed to compare trauma service structures, processes and outcomes between the English National Health Service (NHS) and the province of Quebec, Canada. METHODS: We conducted a multicentre cohort study including admissions of patients aged older than 15 years with major trauma to major trauma centres (MTCs) from 2014/15 to 2016/17. We compared structures descriptively, and time to MTC and time in the emergency department (ED) using Wilcoxon tests. We compared mortality, and hospital and intensive care unit (ICU) length of stay (LOS) using multilevel logistic regression with propensity score adjustment, stratified by body region of the worst injury. RESULTS: The sample comprised 36 337 patients from the NHS and 6484 patients from Quebec. Structural differences in the NHS included advanced prehospital medical teams (v. "scoop and run" in Quebec), helicopter transport (v. fixed-wing aircraft) and trauma team leaders. The median time to an MTC was shorter in Quebec than in the NHS for direct transports (1 h v. 1.5 h, p < 0.001) but longer for transfers (2.5 h v. 6 h, p < 0.001). Time in the ED was longer in Quebec than in the NHS (6.5 h v. 4.0 h, p < 0.001). The adjusted odds of death were higher in Quebec for head injury (odds ratio [OR] 1.28, 95% confidence interval [CI] 1.09-1.51) but lower for thoracoabdominal injuries (OR 0.69, 95% CI 0.52-0.90). The adjusted median hospital LOS was longer for spine, torso and extremity injuries in the NHS than in Quebec, and the median ICU LOS was longer for spine injuries. CONCLUSION: We observed significant differences in the structure of trauma care, delays in access and risk-adjusted outcomes between Quebec and the NHS. Future research should assess associations between structures, processes and outcomes to identify opportunities for quality improvement.

INTRODUCTION: This study aims to assess the sensitivity and specificity of a 5-step prehospital trauma triage protocol to identify older adults who require urgent and specialized trauma care using different age cut-offs to define an older adult (≥55, ≥65, and ≥75 y old). METHODS: Prehospital and in-hospital medical records were reviewed for injured patients transported by an ambulance to an emergency department (ED) between November 11, 2016 and March 3, 2017 in Quebec City, Canada. Sensitivities and specificities were calculated to assess the accuracy of our prehospital trauma triage protocol to identify patients who required at least one urgent in-hospital trauma intervention. RESULTS: A total of 822 patients were included of which 62.9% were ≥55 y old and 56.3% were female. Fall (65.8%) was the main trauma mechanism. Seventy-six (9.2%) patients required urgent trauma care. This proportion was similar regardless of age (8.9%-9.5%). The proportion of patients who needed to be transported to the level-1 trauma center as per the triage protocol tended to decrease with increasing age (20.6% [whole cohort], 15.3% [≥55 y old], 11.4% [≥65 y old], and 9.0% [≥75 y old]). The sensitivity of the protocol for steps 1, 2, and 3 was 56.6% (whole cohort) and 30.0% for patients aged ≥75 y. The specificity ranged between 83.1% (whole cohort) and 93.1% (≥75 y old). CONCLUSIONS: Our prehospital trauma triage protocol has insufficient sensitivity to identify patients with urgent trauma care needs, particularly in older adults.

OBJECTIVES: Underuse of high-value clinical practices and overuse of low-value practices are major sources of inefficiencies in modern healthcare systems. To achieve value-based care, guidelines and recommendations should target both underuse and overuse and be supported by evidence from economic evaluations. We aimed to conduct a systematic review of the economic value of in-hospital clinical practices in acute injury care to advance knowledge on value-based care in this patient population. METHODS: Pairs of independent reviewers systematically searched MEDLINE, Embase, Web of Science, and Cochrane Central Register for full economic evaluations of in-hospital clinical practices in acute trauma care published from 2009 to 2019 (last updated on June 17, 2020). Results were converted into incremental net monetary benefit and were summarized with forest plots. The protocol was registered with PROSPERO (CRD42020164494). RESULTS: Of 33 910 unique citations, 75 studies met our inclusion criteria. We identified 62 cost-utility, 8 cost-effectiveness, and 5 cost-minimization studies. Values of incremental net monetary benefit ranged from international dollars -467 000 to international dollars 194 000. Of 114 clinical interventions evaluated (vs comparators), 56 were cost-effective. We identified 15 cost-effective interventions in emergency medicine, 6 in critical care medicine, and 35 in orthopedic medicine. A total of 58 studies were classified as high quality and 17 as moderate quality. From studies with a high level of evidence (randomized controlled trials), 4 interventions were clearly dominant and 8 were dominated. CONCLUSIONS: This research advances knowledge on value-based care for injury admissions. Results suggest that almost half of clinical interventions in acute injury care that have been studied may not be cost-effective.

BACKGROUND: The knowledge gap regarding acute care resource use for patients with traumatic brain injury (TBI) impedes efforts to improve the efficiency and quality of the care of these patients. Our objective was to evaluate interhospital variation in resource use for patients with TBI, identify determinants of high resource use and assess the association between hospital resource use and clinical outcomes. METHODS: We conducted a multicentre retrospective cohort study including patients aged 16 years and older admitted to the inclusive trauma system of Quebec following TBI, between 2013 and 2016. We estimated resource use using activity-based costs. Clinical outcomes included mortality, complications and unplanned hospital readmission. Interhospital variation was evaluated using intraclass correlation coefficients (ICCs) with 95% confidence intervals (CIs). Correlations between hospital resource use and clinical outcomes were evaluated using correlation coefficients on weighted, risk-adjusted estimates with 95% CIs. RESULTS: We included 6319 patients. We observed significant interhospital variation in resource use for patients discharged alive, which was not explained by patient case mix (ICC 0.052, 95% CI 0.043 to 0.061). Adjusted mean resource use for patients discharged to long-term care was more than twice that of patients discharged home. Hospitals with higher resource use tended to have a lower incidence of mortality (r -0.347, 95% CI -0.559 to -0.087) and unplanned readmission (r -0.249, 95% CI -0.481 to 0.020) but a higher incidence of complications (r 0.491, 95% CI 0.255 to 0.666). CONCLUSION: Resource use for TBI varies significantly among hospitals and may be associated with differences in mortality and morbidity. Negative associations with mortality and positive associations with complications should be interpreted with caution but suggest there may be a trade-off between adverse events and survival that should be evaluated further.

OBJECTIVES: Low-value clinical practices have been identified as one of the most important areas of excess healthcare spending. Nevertheless, there is a knowledge gap on the scale of this problem in injury care. We aimed to identify clinical practice guideline (CPG) recommendations pertaining to low-value injury care, estimate how frequently they are used in practice, and evaluate interhospital variations in their use. METHODS: We identified low-value clinical practices from internationally recognized CPGs. We conducted a retrospective cohort study using data from a Canadian trauma system (2014-2019) to calculate frequencies and assess interhospital variations. RESULTS: We identified 29 low-value practices. Fourteen could be measured using trauma registry data. The 3 low-value clinical practices with the highest absolute and relative frequencies were computed tomography (CT) in adults with minor head injury (n = 5591, 24%), cervical spine CT (n = 2742, 31%), and whole-body CT in minor or single-system trauma (n = 530, 32%). We observed high interhospital variation for decompressive craniectomy in diffuse traumatic brain injury. Frequencies and interhospital variations were low for magnetic resonance imaging, intracranial pressure monitoring, inferior vena cava filter use, and surgical management of blunt abdominal injuries. CONCLUSIONS: We observed evidence of poor adherence to CPG recommendations on low-value CT imaging and high practice variation for decompressive craniectomy. Results suggest that adherence to recommendations for the 10 other low-value practices is high. These data can be used to advance the research agenda on low-value injury care and inform the development of interventions targeting reductions in healthcare overuse in this population.

OBJECTIVE: To provide an expert consensus definition of persistent postconcussion symptoms following a mild traumatic brain injury (mTBI). PARTICIPANTS: Canadian healthcare professionals caring for patients with mTBI. DESIGN: Online Delphi process. MAIN MEASURES: A first Delphi round documented important dimensions or criteria to consider when defining persistent symptoms. Expert opinions were then resubmitted in 4 subsequent Delphi rounds and their relevance was rated using a 9-point Likert scale. An item with a median rating of 7 or more and a sufficient level of agreement were considered consensual. RESULTS: After 5 rounds, consensus was reached on a set of criteria that can be summarized as follows: presence of any symptom that cannot be attributed to a preexisting condition and that appeared within hours of an mTBI, that is still present every day 3 months after the trauma, and that has an impact on at least one sphere of a person's life. CONCLUSION: This Delphi consensus proposes a set of criteria that support a more uniform definition of persistent symptoms in mild TBI among clinicians and researchers. This definition may help clinicians better identify persistent postconcussion symptoms and improve patient management.

BACKGROUND: Clinical assessment of patients with mild traumatic brain injury (mTBI) is challenging and overuse of head CT in the ED is a major problem. Several studies have attempted to reduce unnecessary head CTs following a mTBI by identifying new tools aiming to predict intracranial bleeding. Higher levels of S100B protein have been associated with intracranial haemorrhage following a mTBI in previous literature. The main objective of this study is to assess whether plasma S100B protein level is associated with clinically significant brain injury and could be used to reduce the number of head CT post-mTBI. METHODS: Study design: secondary analysis of a prospective multicentre cohort study conducted between 2013 and 2016 in five Canadian EDs. Inclusion criteria: non-hospitalised patients with mTBI with a GCS score of 13-15 in the ED and a blood sample drawn within 24 hours after the injury. Data collected: sociodemographic and clinical data were collected in the ED. S100B protein was analysed using ELISA. All CT scans were reviewed by a radiologist blinded to the biomarker results. Main outcome: the presence of clinically important brain injury. RESULTS: 476 patients were included. Mean age was 41±18 years old and 150 (31.5%) were women. Twenty-four (5.0%) patients had a clinically significant intracranial haemorrhage. Thirteen patients (2.7%) presented a non-clinically significant brain injury. A total of 37 (7.8%) brain injured patients were included in our study. S100B median value (Q1-Q3) was: 0.043 µg/L (0.008-0.080) for patients with clinically important brain injury versus 0.039 µg/L (0.023-0.059) for patients without clinically important brain injury. Sensitivity and specificity of the S100B protein level, if used alone to detect clinically important brain injury, were 16.7% (95% CI 4.7% to 37.4%) and 88.5% (95% CI 85.2% to 91.3%), respectively. CONCLUSION: Plasma S100B protein level was not associated with clinically significant intracranial lesion in patients with mTBI.

Background: There is a growing trend toward verification of trauma centres, but its impact remains unclear. This systematic review aimed to synthesize available evidence on the effectiveness of trauma centre verification. Methods: We conducted a systematic search of the CINAHL, Embase, HealthStar, MEDLINE and ProQuest databases, as well as the websites of key injury organizations for grey literature, from inception to June 2019, without language restrictions. Our population consisted of injured patients treated at trauma centres. The intervention was trauma centre verification. Comparison groups comprised nonverified trauma centres, or the same centre before it was first verified or re-verified. The primary outcome was in-hospital mortality; secondary outcomes included adverse events, resource use and processes of care. We computed pooled summary estimates using random-effects meta-analysis. Results: Of 5125 citations identified, 29, all conducted in the United States, satisfied our inclusion criteria. Mortality was the most frequently investigated outcome (n = 20), followed by processes of care (n = 12), resource use (n = 12) and adverse events (n = 7). The risk of bias was serious to critical in 22 studies. We observed an imprecise association between verification and decreased mortality (relative risk 0.74, 95% confidence interval 0.52 to 1.06) in severely injured patients. Conclusion: Our review showed mixed and inconsistent associations between verification and processes of care or patient outcomes. The validity of the published literature is limited by the lack of robust controls, as well as any evidence from outside the US, which precludes extrapolation to other health care jurisdictions. Quasiexperimental studies are needed to assess the impact of trauma centre verification. Systematic reviews registration: PROSPERO no. CRD42018107083.
Contexte: Le processus d'audit des centres de traumatologie gagne en popularité, mais ses effets concrets ne sont pas bien connus. La présente revue systématique a cherché à résumer les données probantes disponibles sur l'efficacité de l'audit des centres de traumatologie. Méthodes: Nous avons effectué des recherches systématiques dans les bases de données CINAHL, Embase, HealthSTAR, MEDLINE et ProQuest, de même qu'une recherche dans la littérature grise sur les sites Web d'organisations majeures du domaine des traumas, de leur création à juin 2019, sans restriction de langue. La population à l'étude était l'ensemble des patients blessés traités en centre de traumatologie. L'intervention était l'audit du centre de traumatologie. Les groupes de comparaison correspondaient aux centres de traumatologie n'ayant pas subi d'audit, ou le même centre, avant son premier audit ou un audit subséquent. Le principal résultat à l'étude était la mortalité en milieu hospitalier; les résultats secondaires étaient les événements indésirables, l'utilisation des ressources et les processus de soins. Nous avons calculé des estimations sommaires par méta-analyse à effets aléatoires sur données groupées. Résultats: Sur les 5125 citations retenues, 29 publications sur des études menées aux États-Unis répondaient à nos critères d'inclusion. La mortalité était le résultat le plus souvent à l'étude (n = 20), puis suivaient les processus de soins (n = 12), l'utilisation des ressources (n = 12) et les événements indésirables (n = 7). Le risque de biais était important ou critique dans 22 études. Nous avons observé une association imprécise entre l'audit et une baisse de la mortalité (risque relatif 0,74; intervalle de confiance à 95 % 0,52 à 1,06) chez les patients ayant subi un trauma grave. Conclusion: Notre revue a conclu qu'il y avait des associations mitigées et manquant d'uniformité entre l'audit et les processus de soins ou les issues pour les patients. La validité des données à l'étude était limitée par un manque de contrôles fiables, ainsi que par l'absence de données provenant d'autres pays que les États-Unis, ce qui empêche l'extrapolation à d'autres systèmes de santé. Des études quasi expérimentales devront être menées pour évaluer les effets de l'audit des centres de traumatologie. Enregistrement de la revue systématique: Registre PROSPERO, numéro CRD42018107083.

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.

OBJECTIVES: The primary objective of this study was to determine the incidence of clinically significant traumatic intracranial hemorrhage (T-ICH) following minor head trauma in older adults. Secondary objective was to investigate the impact of anticoagulant and antiplatelet therapies on T-ICH incidence. METHODS: This retrospective cohort study extracted data from electronic patient records. The cohort consisted of patients presenting after a fall and/or head injury and presented to one of five ED between 1st March 2010 and 31st July 2017. Inclusion criteria were age ≥ 65 years old and a minor head trauma defined as an impact to the head without fulfilling criteria for traumatic brain injury. RESULTS: From the 1,000 electronic medical records evaluated, 311 cases were included. The mean age was 80.1 (SD 7.9) years. One hundred and eighty-nine (189) patients (60.8%) were on an anticoagulant (n = 69), antiplatelet (n = 130) or both (n = 16). Twenty patients (6.4%) developed a clinically significant T-ICH. Anticoagulation and/or antiplatelets therapies were not associated with an increased risk of clinically significant T-ICH in this cohort (Odds ratio (OR) 2.7, 95% CI 0.9-8.3). CONCLUSIONS: In this cohort of older adults presenting to the ED following minor head trauma, the incidence of clinically significant T-ICH was 6.4%.

BACKGROUND: Injuries represent one of the leading causes of preventable morbidity and mortality. For countries with ageing populations, admissions of injured older patients are increasing exponentially. Yet, we know little about hospital resource use for injured older patients. Our primary objective was to evaluate inter-hospital variation in the risk-adjusted resource use for injured older patients. Secondary objectives were to identify the determinants of resource use and evaluate its association with clinical outcomes. METHODS: We conducted a multicenter retrospective cohort study of injured older patients (≥65 years) admitted to any trauma centres in the province of Quebec (2013-2016, N = 33,184). Resource use was estimated using activity-based costing and modelled with multilevel linear models. We conducted separate subgroup analyses for patients with trauma and fragility fractures. RESULTS: Risk-adjusted resource use varied significantly across trauma centres, more for older patients with fragility fractures (intra-class correlation coefficients [ICC] = 0.093, 95% CI [0.079, 0.102]) than with trauma (ICC = 0.047, 95% CI = 0.035-0.051). Risk-adjusted resource use increased with age, and the number of comorbidities, and varied with discharge destination (P < 0.001). Higher hospital resource use was associated with higher incidence of complications for trauma (Pearson correlation coefficient [r] = 0.5, 95% CI = 0.3-0.7) and fragility fractures (r = 0.5, 95% CI = 0.3-0.7) and with higher mortality for fragility fractures (r = 0.4, 95% CI = 0.2-0.6). CONCLUSIONS: We observed significant inter-hospital variations in resource use for injured older patients. Hospitals with higher resource use did not have better clinical outcomes. Hospital resource use may not always positively impact patient care and outcomes. Future studies should evaluate mechanisms, by which hospital resource use impacts care.

This study assessed whether S-100ß protein could be measured in urine when detectable in plasma after a mild traumatic brain injury (mTBI). Clinical data, plasma and urine samples were collected for the 46 adult patients prospectively enrolled in the emergency department (ED) of a Level 1 trauma center. S-100ß protein concentrations were analysed using ELISA. S-100ß protein was detectable in 91% and 71% of plasma and urine samples, but values were not correlated (r = 0.002). Urine sampling would have been a non-invasive procedure, but it does not appear to be useful in the ED during the acute phase after an mTBI.
Détection de la protéine S-100ß dans le plasma et l'urine à la suite d'un traumatisme cranio-cérébral léger (TCCL). Cette étude a cherché à évaluer dans quelle mesure la teneur en protéine S-100ß peut être mesurée dans l'urine après avoir été détectée dans le plasma, et ce, à la suite d'un TCCL. Des données cliniques ainsi que des échantillons de plasma et d'urine ont alors été collectés chez quarante-six patients adultes recrutés de façon prospective dans le service d'urgence d'un centre tertiaire de traumatologie. La teneur en protéine S-100ß a été analysée au moyen de la méthode immuno-enzymatique ELISA. La protéine S-100ß s'est avérée détectable dans respectivement 91 % et 71 % des échantillons de plasma et d'urine. Cela dit, les valeurs obtenues ne sont pas apparues corrélées (r = 0,002). Le fait de recourir à des échantillons d'urine aurait pu représenter une procédure non-invasive ; cependant, elle ne semble pas utile dans un service d'urgence lors de la phase aigüe consécutive à un TCCL.

BACKGROUND: The effectiveness of trauma systems in decreasing injury mortality and morbidity has been well demonstrated. However, little is known about which components contribute to their effectiveness. We aimed to systematically review the evidence of the impact of trauma system components on clinically important injury outcomes. METHODS: We searched MEDLINE, EMBASE, Cochrane CENTRAL, and BIOSIS/Web of Knowledge, gray literature and trauma association Web sites to identify studies evaluating the association between at least one trauma system component and injury outcome. We calculated pooled effect estimates using inverse-variance random-effects models. We evaluated quality of evidence using GRADE criteria. RESULTS: We screened 15,974 records, retaining 41 studies for qualitative synthesis and 19 for meta-analysis. Two recommended trauma system components were associated with reduced odds of mortality: inclusive design (odds ratio [OR] = 0.72 [0.65-0.80]) and helicopter transport (OR = 0.70 [0.55-0.88]). Pre-Hospital Advanced Trauma Life Support was associated with a significant reduction in hospital days (mean difference [MD] = 5.7 [4.4-7.0]) but a nonsignificant reduction in mortality (OR = 0.78 [0.44-1.39]). Population density of surgeons was associated with a nonsignificant decrease in mortality (MD = 0.58 [-0.22 to 1.39]). Trauma system maturity was associated with a significant reduction in mortality (OR = 0.76 [0.68-0.85]). Quality of evidence was low or very low for mortality and healthcare utilization. CONCLUSIONS: This review offers low-quality evidence for the effectiveness of an inclusive design and trauma system maturity and very-low-quality evidence for helicopter transport in reducing injury mortality. Further research should evaluate other recommended components of trauma systems and non-fatal outcomes and explore the impact of system component interactions.

PURPOSE OF THE STUDY: This study aims to describe all unsolicited electronic invitations received from potential predatory publishers or fraudulent conferences over a 12-month period following the first publication as a corresponding author of a junior academician. STUDY DESIGN: Unsolicited invitations received at an institutional email address and perceived to be sent by predatory publishers or fraudulent conferences were collected. RESULTS: A total of 502 invitations were included of which 177 (35.3%) had subject matter relevant to the recipient's research interests and previous work. Two hundred and thirty-seven were invitations to publish a manuscript. Few disclosed the publication fees (32, 13.5%) but they frequently reported accepting all types of manuscripts (167, 70.5%) or emphasised on a deadline to submit (165, 69.6%). Invitations came from 39 publishers (range 1 to 87 invitations per publisher). Two hundred and ten invitations from a potential fraudulent conference were received. These meetings were held in Europe (97, 46.2%), North America (65, 31.0%), Asia (20.4%) or other continents (5, 2.4%) and came from 18 meeting organisation groups (range 1 to 137 invitations per organisation). Becoming an editorial board member (30), the editor-in-chief (1), a guest editor for journal special issue (6) and write a book chapter (11) were some of the roles offered in the other invitations included while no invitation to review a manuscript was received. CONCLUSIONS: Young researchers are commonly exposed to predatory publishers and fraudulent conferences following a single publication as a corresponding author. Academic institutions worldwide need to educate and inform young researchers of this emerging problem.

BACKGROUND: This systematic review aimed to determine the prognostic value of neuron-specific enolase (NSE) to predict post-concussion symptoms following mild traumatic brain injury (TBI). METHODS: Seven databases were searched for studies evaluating the association between NSE levels and post-concussion symptoms assessed ≥ 3 months (persistent) or ≥ 7 days < 3 months (early) after mild TBI. Two researchers independently screened studies for inclusion, extracted data and appraised quality using the Quality in Prognostic Studies (QUIPS) tool. RESULTS: The search strategy yielded a total of 23,298 citations from which 8 cohorts presented in 10 studies were included. Studies included between 45 and 141 patients (total 608 patients). The outcomes most frequently assessed were post-concussion syndrome (PCS, 12 assessments) and neuropsychological performance deficits (10 assessments). No association was found between an elevated NSE serum level and PCS. Only one study reported a statistically significant association between a higher NSE serum level and alteration of at least three cognitive domains at 2 weeks but this association was no longer significant at 6 weeks. Overall, risk of bias of the included studies was considered moderate. CONCLUSIONS: Early NSE serum level is not a strong independent predictor of post-concussion symptoms following mild TBI.

BACKGROUND: Despite their reported protective effect against the occurrence of head injuries, helmets are still used inconsistently in sports in which they are optional. We aimed to assess the impact of helmet use on the risk of hospitalization and intracranial haemorrhage for trauma occurring during sport activities. METHODS: Retrospective cohort of all patients who presented themselves, over an 18-month period, at the emergency department of a tertiary trauma centre for an injury sustained in a sport or leisure activity where the use of a helmet is optional. Impact of helmet use was assessed using multivariable regression analyses (relative risks, RR). RESULTS: Among the 1,022 patients included in the study, half were cyclists and 40% were skiers or snowboarders. A total of 40 % of patients wore a helmet at the time of injury, 18% had a head injury, 16% were hospitalized and 13% of patients with a head injury had an intracranial haemorrhage. Among all patients, no association was observed between hospital admission and helmet use. However, helmet use in patients with a head injury was associated with significant reductions in the risks of hospitalization (RR 0.41 [95% CI: 0.22-0.76]) and intracranial haemorrhage (RR 0.28 [95% CI: 0.11-0.71]). CONCLUSIONS: Results suggest that, in recreational athletes who sustain a head injury, helmet use is associated with a reduced risk of hospitalization (all sports) and intracranial haemorrhage (cyclists).
