RESUMO
BACKGROUND: Injury severity scales have traditionally been used to assess the performance of prehospital trauma triage protocols, but they correlate weakly with the urgent needs of specialized trauma care interventions. This study aimed to develop a list of in-hospital urgent and specialized trauma care interventions that require direct transport to the highest-level trauma centre within the catchment area. METHODS: Based on a list of potential participants we obtained using data on training, experience, geographic location, affiliations and role within key trauma organizations, we recruited multidisciplinary trauma experts (including prehospital, emergency, surgery and intensive care clinicians, epidemiologists and clinician/decision-makers) from across Canada to complete a 3-round modified Delphi survey. We conducted a literature review of the criteria used to define urgent and specialized trauma care, and included all diagnostic and therapeutic interventions presented in previously published studies in the list of interventions to present to the panellists. The final list was determined by our advisory committee, 5 clinicians with experience in trauma care. Participants were asked to rate their level of agreement for potentially including the 38 items as urgent and specialized trauma care interventions on a 9-point Likert scale. Interventions were retained if more than 67% of participants moderately or strongly agreed (7-9 on the Likert scale). Interventions that did not reach consensus were presented again in the subsequent round. RESULTS: Twenty-three panellists were recruited. The response rate was 91%, 96% and 83% for the 3 rounds. After the Delphi process, 30 of the 38 interventions, including endotracheal intubation, blood product administration and angioembolization, and abdominal, thoracic, neurosurgical, spinal and/or orthopedic operations (excluding hip or limb surgery, and toe or finger amputation), were selected. Hospital admission to the intensive care unit and/or for observation of brain, spinal, thoracic or abdominal injuries were also retained. CONCLUSION: We developed a Canadian consensus-based list of urgent and specialized in-hospital trauma care interventions requiring direct transportation to a major trauma centre. This list should help standardize assessments of current protocols and derive new triage tools.

OBJECTIVES: To describe objective and subjective cognitive functioning older adults who sustained TBI at age 65 or over, and to determine whether cognitive functioning is associated with health-related quality of life (HRQoL) and social participation. METHOD: The sample consisted of 40 individuals with TBI (mean age = 73 years; 65% mild, 35% moderate/severe TBI). On average 15 months post-injury, they completed measures of objective and subjective cognitive functioning (Telephone Interview for Cognitive Status-Modified, Alphaflex, Medical Outcomes Study Cognitive Functioning Scale), HRQoL (SF-12), and social participation (Participation Assessment with Recombined Tools - Objective). RESULTS: Mean score for objective cognitive functioning was lower than normative values, while mean scores for executive functioning and subjective cognitive functioning were comparable to normative values. There was no relationship between objective and subjective measures. Subjective cognitive functioning and (to a lesser extent) global objective cognitive functioning were significantly associated with mental HRQoL but not with physical HRQoL or social participation. CONCLUSION: These results underscore the importance of considering both subjective perception and objective performance when assessing and intervening on cognition to promote better mental HRQoL in older adults with TBI.

BACKGROUND: Published risk tools do not provide possible management options for syncope in the emergency department (ED). Using the 30-day observed risk estimates based on the Canadian Syncope Risk Score (CSRS), we developed personalised risk prediction to guide management decisions. METHODS: We pooled previously reported data from two large cohort studies, the CSRS derivation and validation cohorts, that prospectively enrolled adults (≥16 years) with syncope at 11 Canadian EDs between 2010 and 2018. Using this larger cohort, we calculated the CSRS calibration and discrimination, and determined with greater precision than in previous studies the 30-day risk of adjudicated serious outcomes not identified during the index ED evaluation depending on the CSRS and the risk category. Based on these findings, we developed an on-line calculator and pictorial decision aids. RESULTS: 8233 patients were included of whom 295 (3.6%, 95% CI 3.2% to 4.0%) experienced 30-day serious outcomes. The calibration slope was 1.0, and the area under the curve was 0.88 (95% CI 0.87 to 0.91). The observed risk increased from 0.3% (95% CI 0.2% to 0.5%) in the very-low-risk group (CSRS -3 to -2) to 42.7% (95% CI 35.0% to 50.7%), in the very-high-risk (CSRS≥+6) group (Cochrane-Armitage trend test p<0.001). Among the very-low and low-risk patients (score -3 to 0), ≤1.0% had any serious outcome, there was one death due to sepsis and none suffered a ventricular arrhythmia. Among the medium-risk patients (score +1 to+3), 7.8% had serious outcomes, with <1% death, and a serious outcome was present in >20% of high/very-high-risk patients (score +4 to+11) including 4%-6% deaths. The online calculator and the pictorial aids can be found at: https://teamvenk.com/csrs CONCLUSIONS: 30-day observed risk estimates from a large cohort of patients can be obtained for management decision-making. Our work suggests very-low-risk and low-risk patients may be discharged, discussion with patients regarding investigations and disposition are needed for medium-risk patients, and high-risk patients should be hospitalised. The online calculator, accompanied by pictorial decision aids for the CSRS, may assist in discussion with patients.

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: Older patients (age ≥ 65 yr) with trauma have increased morbidity and mortality compared to younger patients; this is partly explained by undertriage of older patients with trauma, resulting in lack of transfer to a trauma centre or failure to activate the trauma team. The objective of this study was to identify modifiers to the prehospital and emergency department phases of major trauma care for older adults based on expert consensus. Methods: We conducted a modified Delphi study between May and September 2019 to identify major trauma care modifiers for older adults based on national expert consensus. The panel consisted of 24 trauma care professionals from across Canada from the prehospital and emergency department phases of care. The survey consisted of 16 trauma care modifiers. Three online survey rounds were distributed. Consensus was defined a priori as a disagreement index score less than 1. Results: There was a 100% response rate for all survey rounds. Three new trauma care modifiers were suggested by panellists. The panel achieved consensus agreement for 17 of the 19 trauma care modifiers. The prehospital modifier with the strongest agreement to transfer to a trauma centre was a respiratory rate less than 10 or greater than 20 breaths/min or need for ventilatory support. The emergency department modifier with the strongest level of agreement was obtaining 12-lead electrocardiography following the primary and secondary survey. Conclusion: Using a modified Delphi process, an expert panel agreed on 17 trauma care modifiers for older adults in the prehospital and emergency department settings. These modifiers may improve the delivery of trauma care for older adults and should be considered when developing local and national trauma guidelines.
Contexte: Les polytraumatisés âgés (≥ 65 ans) sont exposés à un risque plus grand de morbidité et de mortalité comparativement aux jeunes polytraumatisés; cela s'explique en partie par un triage inadéquat des patients âgés victimes de traumatismes, qui fait en sorte qu'on ne les oriente pas vers un centre de traumatologie ou qu'on ne fait pas intervenir l'équipe de traumatologie. L'objectif de la présente étude était d'identifier les éléments de soins à modifier au stade préhospitalier et en médecine d'urgence lors de la prise en charge des cas de traumatismes graves chez les adultes âgés, sur la base d'un consensus d'experts. Méthodes: Nous avons procédé à une analyse Delphi modifiée entre mai et septembre 2019 pour recenser les éléments de soins à modifier chez les polytraumatisés âgés à partir d'un consensus national d'experts. Le panel d'experts se composait de 24 professionnels en traumatologie du Canada entier chargés des soins au stade préhospitalier et en médecine d'urgence. Le questionnaire portait sur 16 éléments à modifier en traumatologie. Trois questionnaires successifs ont été distribués en ligne. Le consensus était défini a priori par un indice de désaccord inférieur à 1. Résultats: Le taux de réponse a été de 100 % pour les 3 questionnaires. Les membres du comité ont suggéré 3 nouveaux éléments à modifier. Le comité est arrivé à un consensus pour 17 des éléments à modifier sur 19. L'élément préhospitalier ayant fait l'objet du plus solide consensus concernant le transfert vers un centre de traumatologie était une fréquence respiratoire inférieure à 10 ou supérieure à 20 respirations/minute ou la nécessité d'une assistance respiratoire. L'élément à modifier parmi les soins prodigués à l'urgence ayant fait l'objet du plus solide consensus après les 2 premiers questionnaires était l'obtention d'un électrocardiogramme à 12 dérivations. Conclusion: À l'aide d'une analyse Delphi modifiée, un comité d'expert s'est entendu sur 17 éléments de soins à modifier chez les polytraumatisés âgés au stade préhospitalier et en médecine d'urgence. Ces éléments pourraient améliorer les soins aux adultes âgés et méritent d'être pris en compte lors de la création de lignes directrices locales et nationales en traumatologie.

BACKGROUND: The benefit of hospital admission after emergency department evaluation for syncope is unclear. We sought to determine the association between hospital admission and detection of serious adverse events, and whether this varied according to the Canadian Syncope Risk Score (CSRS). METHODS: We conducted a secondary analysis of a multicentre prospective cohort of patients assessed in the emergency department for syncope. We compared patients admitted to hospital and discharged patients, using propensity scores to match 1:1 for risk of a serious adverse event. The primary outcome was detection of a serious adverse event in hospital for admitted patients or within 30 days after emergency department disposition for discharged patients. RESULTS: We included 8183 patients, of whom 743 (9.1%) were admitted; 658/743 (88.6%) were matched. Admitted patients had higher odds of detection of a serious adverse event (odds ratio [OR] 5.0, 95% confidence interval [CI] 3.3-7.4), nonfatal arrhythmia (OR 5.1, 95% CI 2.9-8.8) and nonarrhythmic serious adverse event (OR 6.3, 95% CI 2.9-13.5). There were no significant differences between the 2 groups in death (OR 1.0, 95% CI 0.4-2.7) or detection of ventricular arrhythmia (OR 2.0, 95% CI 0.7-6.0). Differences between admitted and discharged patients in detection of serious adverse events were greater for those with a CSRS indicating medium to high risk (p = 0.04). INTERPRETATION: Patients with syncope were more likely to have serious adverse events identified within 30 days if they were admitted to hospital rather than discharged from the emergency department. However, the benefit of hospital admission is low for patients at low risk of a serious adverse event.

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: The validated Pediatric Emergency Care Applied Network (PECARN) rule helps determine the relevance of a head computerized tomography (CT) for children with mild traumatic brain injury (mTBI). We sought to estimate the potential overuse of head CT within two Canadian emergency departments (EDs). METHODS: We conducted a retrospective chart review of children seen in 2016 in a paediatric Level I (site 1) and a general Level II (site 2) trauma centre. We reviewed charts to determine the appropriateness of head CT use according to the PECARN rule in a random subset of children presenting with head trauma. Simple descriptive statistics were applied. RESULTS: One thousand five hundred and forty-six eligible patients younger than 17 years consulted during the study period. Of the 203 randomly selected cases per setting, 16 (7.9%) and 24 (12%), respectively from sites 1 and 2 had a head CT performed. Based on the PECARN rule, we estimated the overuse for the younger group (<2 years) to be below 3% for both hospitals without significant difference between them. For the older group (≥2 years), the overuse rate was higher at site 2 (9.3%, 95% confidence interval [CI]: 4.8 to 17% versus 1.2%, 95% CI: 0.2 to 6.5%, P=0.03). CONCLUSION: Both EDs demonstrated overuse rates below 10% although it was higher for the older group at site 2. Such low rates can potentially be explained by the university affiliation of both hospitals and by two Canadian organizations working to raise awareness among physicians about the overuse of diagnostic tools and dangers inherent to radiation.
RESUMO
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.

OBJECTIVE: With the ageing population, the prevalence of mild traumatic brain injury (mTBI) among older patients is increasing, and the age criteria of the Canadian CT head rule (CCHR) is challenged by many emergency physicians. We modified the age criteria of the CCHR to evaluate its predictive capacity. METHODS: We conducted a retrospective cohort study at a level 1 trauma centre ED of all mTBI patients 65 years old and over with an mTBI between 2010 and 2014. Main outcome was a clinically important brain injury (CIBI) reported on CT. The clinical and radiological data collection was standardised. Univariate analyses were performed to measure the predictive capacities of different age cut-offs at 70, 75 and 80 years old. RESULTS: 104 confirmed mTBI were included; CT scan identified 32 (30.8%) CIBI. Sensitivity and specificity (95% CI) of the CCHR were 100% (89.1 to 100) and 4.2% (0.9 to 11.7) for a modified criteria of 70 years old; 100% (89.1 to 100) and 13.9% (6.9 to 24.1) for 75 years old; and 90.6% (75.0 to 98.0) and 23.6% (14.4 to 35.1) for 80 years old. Furthermore, modifying the age criteria to 75 years old showed a reduction of CT up to 25% (n=10/41) among the individuals aged 65-74 without missing CIBI. CONCLUSION: Adjusting the age criteria of the Canadian CT head rule to 75 years old could be safe while reducing radiation and ED resources. A future prospective study is suggested to confirm the proposed modification.

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).

OBJECTIVE: To compare gait parameters between children in early adolescence (EA) with and without a mild traumatic brain injury (mTBI) during dual-task walking (DTW). METHODS: Children in EA with mTBI (n = 14; six girls) were compared to those without (n = 13; five girls) while walking in different combinations of obstacle avoidance and cognitive dual-tasks. Gait speed and fluidity and their related dual-task costs (DTC) were analysed along with foot clearance and proximity to the obstacle. RESULTS: No group effects were found for gait speed, proximity or clearance, but were found for fluidity DTC, specifically during the dual Stroop task and when crossing the deeper obstacle. There were also group differences for fluidity during the planning of obstacle avoidance for the narrow obstacle combined with the verbal fluency task and the deep obstacle with no cognitive task. Finally, gait fluidity showed group differences across unobstructed dual-task situations. CONCLUSIONS: Gait fluidity may be a more sensitive variable than gait speed for revealing executive dysfunction following mTBI in EA. Assessing DTW in level walking also seems to show a potential to reveal executive dysfunctions in this age group. These results provide direction for future research on clinical assessment using DTW post-mTBI in adolescents.

OBJECTIVE: To investigate whether minor thoracic injuries (MTIs) relate to subsequent functional limitations. BACKGROUND: Approximately 75% of patients with an MTI are discharged after an emergency department (ED) visit, whereas significant functional limitations can occur in the weeks that follow. METHODS: A 19 months' prospective cohort study with a 90-day follow-up was conducted at 4 university-affiliated EDs. Patients 16 years and older with an MTI were assessed at initial ED visit, 7, 14, 30, and 90 days after injury. Functional outcome was measured using the SF-12 scale. General linear model were used to assess outcome. RESULTS: A total of 482 patients were included, of whom 127 (26.3%) were 65 or older. Overall, 147 patients (30.5%) presented with at least 1 rib fracture and 59 subjects (12.2%) with delayed hemothorax. At 90 days, 22.8% of patients still had severe or moderate disabilities on global physical health score. Patients with solely delayed hemothorax and no rib fracture had the lowest global physical health score (46.4 vs 61.1, P < 0.01, effect sizeâ=â -2.60) than patients with simple MTI. Generally, functional limitations also increase with increments of number of rib fracture detected on radiograph. Outcomes were not different among patients 65 years or older when compared to their younger counterparts. CONCLUSIONS: In this prospective study of MTIs, severe to moderate disabilities were present in nearly 1 patient out of 5 at 90 days. The presence of delayed hemothorax and the number of rib fracture were associated with increased functional limitations after a MTI.

OBJECTIVE: This study aimed to (i) describe unplanned readmission rates after injury according to time, reason, and place; (ii) compare observed rates with general population rates, and (iii) identify determinants of 30-day readmission. BACKGROUND: Hospital readmissions represent an important burden in terms of mortality, morbidity, and resource use but information on unplanned rehospitalization after injury admissions is scarce. METHODS: This multicenter retrospective cohort study was based on adults discharged alive from a Canadian provincial trauma system (1998-2010; n = 115,329). Trauma registry data were linked to hospital discharge data to obtain information on readmission up to 12 months postdischarge. Provincial admission rates were matched to study data by age and gender to obtain expected rates. Determinants of readmission were identified using multiple logistic regression. RESULTS: Cumulative readmission rates at 30 days, 3 months, 6 months, and 12 months were 5.9%, 10.9%, 15.5%, and 21.1%, respectively. Observed rates persisted above expected rates up to 11 months postdischarge. Thirty percent of 30-day readmissions were due to potential complications of injury compared with 3% for general provincial admissions. Only 23% of readmissions were to the same hospital. The strongest independent predictors of readmission were the number of prior admissions, discharge destination, the number of comorbidities, and age. CONCLUSIONS: Unplanned readmissions after discharge from acute care for traumatic injury are frequent, persist beyond 30 days, and are often related to potential complications of injury. Several patient-, injury-, and hospital-related factors are associated with the risk of readmission. Injury readmission rates should be monitored as part of trauma quality assurance efforts.

PURPOSE/OBJECTIVE: In care partners of older persons (65 years and older) having sustained traumatic brain injury (TBI), the objectives were (a) to describe subjective burden (emotional, social, financial, and physical burden), objective burden (new roles and responsibilities), and psychological distress at 4 months postinjury, and (b) to explore the predictors of subjective burden and psychological distress. RESEARCH METHOD/DESIGN: This is an observational study of care partners of older adults with TBI (n = 46; Mage = 65.2 years, SD = 11.2, 87% female). Participants completed the Zarit Burden Interview, the Hospital Anxiety and Depression Scale, the Brain Injury Complaint Questionnaire (measuring difficulties of the injured older adult perceived by the care partner), and the modified Medical Outcomes Study Social Support Survey. RESULTS: A majority of care partners (88%) reported at least one form of objective burden (e.g., increased/decreased time spent in certain activities post-TBI), 29% perceived at least mild subjective burden, and 27% reported either significant anxiety or depressive symptoms. Linear regressions indicated that a higher number of difficulties reported regarding the injured person and poorer perceived social support predicted higher subjective burden and psychological distress. A younger age of the care partner also predicted a higher subjective burden. CONCLUSIONS/IMPLICATIONS: This study provides a better understanding of the potential impacts of TBI in older age for care partners. Future research should examine how to support adequately care partners in their psychological adaptation after TBI in an elderly person. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

BACKGROUND: Wide variations in emergency department (ED) syncope management exist. The Canadian Syncope Risk Score (CSRS) was developed to predict the probability of 30-day serious outcomes after ED disposition. Study objectives were to evaluate the acceptability of proposed CSRS practice recommendations among providers and patients, and identify barriers and facilitators for CSRS use to guide disposition decisions. METHODS: We conducted semi-structured interviews with 41 physicians involved in ED syncope and 35 ED patients with syncope. We used purposive sampling to ensure a variety of physician specialties and CSRS patient risk levels. Thematic analysis was completed by two independent coders with consensus meetings to resolve conflicts. Analysis proceeded in parallel with interviews until data saturation. RESULTS: The majority (97.6%; 40/41) of physicians agreed with discharge of low risk (CSRS ≤ 0) but opined that 'no follow up' changed to 'follow-up as needed'. Physicians indicated current practices do not align with the medium-risk recommendation to discharge patients with 15-day monitoring (CSRS = 1-3; due to lack of access to monitors and timely follow-up) and the high-risk recommendation (CSRS ≥ 4) to potentially discharge patients with 15-day monitoring. Physicians recommended brief hospitalization of high-risk patients due to patient safety concerns. Facilitators included the CSRS-based patient education and scores supporting their clinical gestalt. Patients reported receiving varying levels of information regarding syncope and post-ED care, were satisfied with care received and preferred less resource intensive options. CONCLUSION: Our recommendations based on the study results were: discharge of low-risk patients with physician follow-up as needed; discharge of medium-risk patients with 15-day cardiac monitoring and brief hospitalization of high-risk patients with 15-day cardiac monitoring if discharged. Patients preferred less resource intensive options, in line with CSRS recommended care. Implementation should leverage identified facilitators (e.g., patient education) and address the barriers (e.g., monitor access) to improve ED syncope care.
RéSUMé: CONTEXTE: La prise en charge des syncopes par les services d'urgence varie considérablement. Le Canadian Syncope Risk Score (CSRS) a été mis au point pour prédire la probabilité d'une issue grave à 30 jours après la prise en charge par le service des urgences. Les objectifs de l'étude étaient d'évaluer l'acceptabilité des recommandations pratiques proposées par le CSRS parmi les prestataires et les patients, et d'identifier les barrières et les facilitateurs de l'utilisation du CSRS pour guider les décisions de disposition. MéTHODES: Nous avons mené des entretiens semi-structurés avec 41 médecins impliqués dans la syncope aux urgences et 35 patients souffrant de syncope aux urgences. Nous avons utilisé un échantillonnage raisonné pour assurer une variété de spécialités médicales et de niveaux de risque pour les patients du CSRS. L'analyse thématique a été réalisée par deux codeurs indépendants, avec des réunions de consensus pour résoudre les conflits. L'analyse s'est déroulée parallèlement aux entretiens jusqu'à saturation des données. RéSULTATS: La majorité (97,6 % ; 40/41) des médecins étaient d'accord avec la sortie des patients à faible risque (CSRS ≤ 0), mais ont estimé que " pas de suivi " devait être remplacée par " suivi en fonction des besoins ". Les médecins ont indiqué que leurs pratiques actuelles ne sont pas conformes à la recommandation à risque moyen de faire sortir les patients avec une surveillance de 15 jours (CSRS = 1-3 ; en raison du manque d'accès aux moniteurs et au suivi en temps opportun) et à la recommandation à risque élevé (CSRS ≥ 4) de potentiellement faire sortir les patients avec une surveillance de 15 jours. Les médecins ont recommandé une brève hospitalisation des patients à haut risque pour des raisons de sécurité. Les facilitateurs comprenaient l'éducation des patients basée sur le CSRS et les scores soutenant leur gestalt clinique. Les patients ont déclaré avoir reçu différents niveaux d'information concernant la syncope et les soins post-urgence, étaient satisfaits des soins reçus et préféraient des options moins gourmandes en ressources. CONCLUSIONS: Nos recommandations basées sur les résultats de l'étude sont les suivantes : sortie des patients à faible risque avec suivi par un médecin si nécessaire ; la sortie des patients à risque moyen avec une surveillance cardiaque de 15 jours et une brève hospitalisation des patients à risque élevé avec une surveillance cardiaque de 15 jours en cas de sortie. Les patients ont préféré des options moins gourmandes en ressources, conformément aux soins recommandés par le CSRS. La mise en Åuvre devrait s'appuyer sur les facilitateurs identifiés (par exemple, l'éducation des patients) et s'attaquer aux obstacles (par exemple, le contrôle de l'accès) pour améliorer les soins aux urgences en cas de syncope.

Approximately 15 % of individuals who sustained a mild Traumatic Brain Injury (TBI) develop persistent post-concussion symptoms (PPCS). We hypothesized that blood biomarkers drawn in the Emergency Department (ED) could help predict PPCS. The main objective of this project was to measure the association between four biomarkers and PPCS at 90 days post mild TBI. We conducted a prospective cohort study in seven Canadian EDs. Patients aged ≥ 14 years presenting to the ED within 24 h of a mild TBI who were discharged were eligible. Clinical data and blood samples were collected in the ED, and a standardized questionnaire was administered 90 days later to assess the presence of symptoms. The following biomarkers were analyzed: S100B protein, Neuron Specific Enolase (NSE), cleaved-Tau (c-Tau) and Glial Fibrillary Acidic Protein (GFAP). The primary outcome measure was the presence of PPCS at 90 days after trauma. Relative risks and Areas Under the Curve (AUC) were computed. A total of 595 patients were included, and 13.8 % suffered from PPCS at 90 days. The relative risk of PPCS was 0.9 (95 % CI: 0.5-1.8) for S100B ≥ 20 pg/mL, 1.0 (95 % CI: 0.6-1.5) for NSE ≥ 200 pg/mL, 3.4 (95 % CI: 0.5-23.4) for GFAP ≥ 100 pg/mL, and 1.0 (95 % CI: 0.6-1.8) for C-Tau ≥ 1500 pg/mL. AUC were 0.50, 0.50, 0.51 and 0.54, respectively. Among mild TBI patients, S100B protein, NSE, c-Tau or GFAP do not seem to predict PPCS. Future research testing of other biomarkers is needed to determine their usefulness in predicting PPCS.
