Abstract
INTRODUCTION Mild traumatic brain injury is common in children and it can be challenging to accurately identify those in need of urgent medical intervention. The Scandinavian guidelines for management of minor and moderate head trauma in children, the Scandinavian Neurotrauma Committee guideline 2016 (SNC16), were developed to aid in risk stratification and decision-making in Scandinavian emergency departments (EDs). This guideline has been validated externally with encouraging results, but internal validation in the intended healthcare system is warranted prior to broad clinical implementation. OBJECTIVE We aim to validate the diagnostic accuracy of the SNC16 to predict clinically important intracranial injuries (CIII) in paediatric patients suffering from blunt head trauma, assessed in EDs in Sweden and Norway. METHODS AND ANALYSIS This is a prospective, pragmatic, observational cohort study. Children (aged 0-17 years) with blunt head trauma, presenting with a Glasgow Coma Scale of 9-15 within 24 hours postinjury at an ED in 1 of the 16 participating hospitals, are eligible for inclusion. Included patients are assessed and managed according to the clinical management routines of each hospital. Data elements for risk stratification are collected in an electronic case report form by the examining doctor. The primary outcome is defined as CIII within 1 week of injury. Secondary outcomes of importance include traumatic CT findings, neurosurgery and 3-month outcome. Diagnostic accuracy of the SNC16 to predict endpoints will be assessed by point estimate and 95% CIs for sensitivity, specificity, likelihood ratio, negative predictive value and positive predictive value. ETHICS AND DISSEMINATION The study is approved by the ethical board in both Sweden and Norway. Results from this validation will be published in scientific journals, and a tailored development and implementation process will follow if the SNC16 is found safe and effective. TRIAL REGISTRATION NUMBER NCT05964764.

Abstract
Background Deciding whether a cranial Computed Tomography (CT) scan in a patient with minor head trauma (MHT) is necessary or not has always been challenging. Diagnosing Traumatic Brain Injury (TBI) is a fundamental part of MHT managing especially in children who are more vulnerable in terms of brain CT radiation consequences and TBI. Defining some indications to timely and efficiently predict the likelihood of TBI is necessary. Thus, we aimed to determine the impact of clinical findings to predict the need for brain CT in children with MHT. Methods In a prospective cohort study, 200 children (2 to 14 years) with MHT were included from 2019 to 2020. The data of MHT-related clinical findings were gathered. The primary and secondary outcomes were defined as a positive brain CT and any TBI requiring neurosurgery intervention, respectively. In statistical analysis, we performed Binary Logistic regression analysis, Fisher’s exact test and independent samples t-test using SPSS V.26. Results The mean age of participants was 6.5 ± 3.06 years. Ninety patients underwent brain CT. The most common clinical finding and injury mechanism were headache and falling from height, respectively. The results of brain CTs were positive in seven patients (3.5%). We identified three predicting factors for an abnormal brain CT including headache, decreased level of consciousness, and vomiting. Conclusion We showed that repetitive vomiting (≥2), headache, and decreased level of consciousness are predicting factors for an abnormal brain CT in children with MHT.

Abstract
Purpose Traumatic brain injury causes morbidity and mortality worldwide. S100B is the most documented emergency brain biomarker and its urine-assay might be advantageous because of easier sampling. The primary aim was to evaluate urine S100B’s ability to rule out intracranial hemorrhage. Secondary aims included S100B temporal pattern for 48 h post-trauma and chemical properties of urine that affect urine S100B. Methods Patients with head trauma were sampled for serum and urine S100B. Patients who were admitted for intracranial hemorrhage were sampled for 48 h to assess S100B-level, renal function, urine-pH, etc. Results The negative predictive value of serum S100B was 97.0% [95% confidence interval (CI) 89.5–99.2%] and that of urine S100B was 89.1% (95% CI 85.5–91.9%). The specificity of serum S100B was 34.4% (95% CI 27.7–41.6%) and that of urine was 67.1% (95% CI 59.4–74.1%). Urine-pH correlated strongly with urine S100B during the first 6-h post-trauma. Trend-analysis of receiver operator characteristics of S100B in serum, urine the arithmetic difference between serum and urine S100B showed the largest area under the curve for arithmetic difference, which had a negative predictive value of 93.1% (95% CI 89.1–95.8%) and a specificity of 71.8% (95% CI 64.4–78.4%). Conclusion This study cannot support ruling out intracranial hemorrhage with urine S100B. Urine-pH might affect urine S100B and merits further studies. Serum and urine S100B have poor concordance and interchangeability. The arithmetic difference had a slightly better area under the curve and can be worth exploring in certain subgroups.

Abstract
OBJECTIVES Head injury is a common reason for emergency department (ED) attendance. Around 1% of patients have life-threatening injuries, while 80% of patients are discharged. National guidelines (Scottish Intercollegiate Guidelines Network (SIGN)) were introduced in Scotland with the aim of achieving early identification of those with acute intracranial lesions yet safely reducing hospital admissions.This study aims to assess the impact of these guidelines and any effect the national 4-hour ED performance target had on hospital admissions for head injury. SETTING All Scottish hospitals between April 1998 and March 2016. PARTICIPANTS Patients admitted to hospital for head injury or traumatic brain injury (TBI) diagnosed by CT imaging identified using administrative Scottish Information Services Division data. There are 275 hospitals in Scotland. In 2015/2016, there were 571 221 emergency hospital admissions in Scotland. INTERVENTIONS The SIGN head injury guidelines introduced in 2000 and 2009. The 4-hour ED target introduced in 2004. OUTCOMES The monthly rate of hospital admissions for head injury and traumatic brain injury. STUDY DESIGN An interrupted time series analysis. RESULTS The first guideline was associated with a reduction in monthly admissions of 0.14 (95% CI 0.09 to 4.83) per 100 000 population. The 4-hour target was associated with a monthly increase in admissions of 0.13 (95% CI 0.06 to 0.20) per 100 000 population. The second guideline reduced monthly admissions by 0.09 (95% CI-0.13 to -0.05) per 100 000 population. These effects varied between age groups.The guidelines were associated with increased admissions for patients with injuries identified by CT imaging-guideline 1: 0.06 (95% CI 0.004 to 0.12); guideline 2: 0.05 (95% CI 0.04 to 0.06) per 100 000 population. CONCLUSION Increased CT imaging of head injured patients recommended by SIGN guidelines reduced hospital admissions. The 4-hour ED target and the increased identification of TBI by CT imaging acted to undermine this effect.

Abstract
BACKGROUND Clinical decision rules (CDRs) aid in the management of children with traumatic brain injury (TBI). Recently, the Scandinavian Neurotrauma Committee (SNC) has published practical, evidence-based guidelines for children with Glasgow Coma Scale (GCS) scores of 9-15. This study aims to validate these guidelines and to compare them with other CDRs. METHODS A large prospective cohort of children (< 18 years) with TBI of all severities, from ten Australian and New Zealand hospitals, was used to assess the SNC guidelines. Firstly, a validation study was performed according to the inclusion and exclusion criteria of the SNC guideline. Secondly, we compared the accuracy of SNC, CATCH, CHALICE and PECARN CDRs in patients with GCS 13-15 only. Diagnostic accuracy was calculated for outcome measures of need for neurosurgery, clinically important TBI (ciTBI) and brain injury on CT. RESULTS The SNC guideline could be applied to 19,007/20,137 of patients (94.4%) in the validation process. The frequency of ciTBI decreased significantly with stratification by decreasing risk according to the SNC guideline. Sensitivities for the detection of neurosurgery, ciTBI and brain injury on CT were 100.0% (95% CI 89.1-100.0; 32/32), 97.8% (94.5-99.4; 179/183) and 95% (95% CI 91.6-97.2; 262/276), respectively, with a CT/admission rate of 42% (mandatory CT rate of 5%, 18% CT or admission and 19% only admission). Four patients with ciTBI were missed; none needed specific intervention. In the homogenous comparison cohort of 18,913 children, the SNC guideline performed similar to the PECARN CDR, when compared with the other CDRs. CONCLUSION The SNC guideline showed a high accuracy in a large external validation cohort and compares well with published CDRs for the management of paediatric TBI.

Abstract
STUDY OBJECTIVE Two clinical decision rules, the Canadian CT Head Rule and the New Orleans Criteria, set the standard to guide clinicians in determining which patients with minor head trauma need computed tomography (CT) imaging. Both rules were derived with patients with minor head injury who had had a loss of consciousness or witnessed disorientation. No evidence exists for evaluating patients and need for CT imaging with minimal head injury; that is, patients who had a head injury but no loss of consciousness or disorientation and therefore would have been excluded from the Canadian CT Head Rule and New Orleans Criteria trials. We evaluate the Canadian CT Head Rule in patients with head injury without loss of consciousness or witnessed disorientation (minimal head injury). METHODS We studied a prospective convenience sample of patients with minimal head injury who received head CTs as part of their evaluations in the emergency department (ED). Participants were enrolled after head CT was ordered, but before the physician received the imaging results. Physicians were surveyed on their clinical reasoning for ordering imaging in this low-risk cohort of patients. Physicians surveyed consisted of ED attending physicians and senior-level emergency medicine residents. Final patient disposition was recorded when it became available. Patients with positive CT findings had their medical records reviewed for specific disposition, admission length of stay, ICU stay, and any operative or procedural interventions. RESULTS Two hundred forty patients with minimal head injury were enrolled. Five patients (2.1%) had head CTs that were positive for intracranial hemorrhage. All instances of intracranial hemorrhage occurred in patients who were at high or moderate risk by the Canadian CT Head Rule (2 high risk [age], 3 moderate risk [mechanism]). No patient with intracranial hemorrhage went to the ICU or underwent any intervention; the average hospital length of stay was 1.25 days. The Canadian CT Head Rule was 100% sensitive (95% confidence interval 40% to 100%) and 29% specific (95% confidence interval 23% to 35%) for the presence of intracranial hemorrhage. Physicians listed their own reassurance (24.6%), patient reassurance (24.2%), patient expectation (14.6%), and reduction of legal liability (11.7%) as the rationale for ordering head CT in patients with minimal head injury. Shared decisionmaking was used in 51% of cases. CONCLUSION Risk of intracranial hemorrhage in patients with minimal head injury was very low, and even in patients found to have an intracranial hemorrhage, none had any serious adverse outcome (eg, death, intubation, prolonged hospitalization, surgical procedure). The Canadian CT Head Rule was 100% sensitive in this small cohort of patients with minimal head injury. Among our study cohort, which specifically included only patients who had CT scanning, applying the Canadian CT Head Rule may have reduced the need for CT, potentially saving costs and resources. However, because many patients with minimal head injury who present to the ED may not have CTs, it is unclear what effect the broad application of this rule would have on overall CT use. Providers' rationale for obtaining CT was multifactorial. These represent barriers that may need to be overcome before physicians are comfortable changing CT ordering patterns in this group of head injury patients.

Abstract
Background In head trauma cases involving antiplatelet agent treatment, the French Society of Emergency Medicine recommends performing computed tomography (CT) scans to detect brain lesions, 90% of which are normal. The value of CT is still debatable given the scarce number of studies and controversial results. Methods We used the RATED registry (Registry of patient with Antithrombotic agents admitted to an Emergency Department, NCT02706080) to assess factors of cerebral bleeding related to antiplatelet agents following head trauma. Results From January 2014 to December 2015, 993 patients receiving antiplatelet agents were recruited, 293 (29.5%) of whom underwent CT scans for brain trauma. Intracranial bleeding was found in 26 (8.9%). Multivariate analysis revealed these patients more likely to have a history of severe hemorrhage (odds ratio [OR]: 8.47, 95% confidence interval [CI]: 1.56–45.82), dual antiplatelet therapy (OR: 6.46, 95%CI:1.46–28.44), headache or vomiting (OR: 4.27, 95%CI: 1.44–2.60), and abnormal Glasgow coma scale (OR: 8.60; 95%CI: 2.85–25.99) compared to those without intracranial bleeding. The predictive model derived from these variables achieved 98.9% specificity and a negative predictive value of 92%. The area under the ROC curve (AUROC) was 0.85 (95%CI: 0.77–0.93). Conclusions Our study demonstrated that the absence of history of severe hemorrhage, dual antiplatelet therapy, headache or vomiting, and abnormal Glasgow coma scale score appears to predict normal CT scan following traumatic brain injury in patients taking antiplatelets. This finding requires confirmation by prospective studies. Trial registration ClinicalTrials.gov number: NCT02706080.

Abstract
Background The question has been raised whether low dose radiation toward the brain in childhood can affect cognitive functions. Purpose To examine if a head computed tomography (CT) examination in childhood affect later cognitive functions. Material and Methods A total of 147 participants (67 girls/women, 80 boys/men) from a previous randomized controlled trial on management strategies after mild head injury (head CT examination or in-hospital observation) were followed up. Participants were aged 6-16 years (mean age = 11.2 ± 2.8) at first inclusion and 11-24 years (mean age = 17.8 ± 2.9) at follow-up. Computerized neuropsychological measures used for the assessment were motor speed and coordination, reaction time, selective attention, visuospatial ability, verbal and non-verbal short-term and long-term memory, and executive function tests from the neurocognitive test battery EuroCog and the Wechsler Memory Scale III. Results were analyzed with Student's t-tests and multivariate analyses adjusting for sex, age at time of injury/exposure, and age at assessment were performed with Factorial ANOVAs. Results The exposed and unexposed groups did not differ in any of the neuropsychological measures and results did not change when sex, age at time of injury/exposure, and age at assessment were included in the analyses. Conclusion A head CT examination at the age of 6-16 years does not seem to affect later cognitive functions.

Abstract
OBJECTIVE We aim to formulate evidence-based recommendations to assist physicians decision-making in the assessment and management of children younger than 16 years presenting to the emergency department (ED) following a blunt head trauma with no suspicion of non-accidental injury. METHODS These guidelines were commissioned by the Italian Society of Pediatric Emergency Medicine and include a systematic review and analysis of the literature published since 2005. Physicians with expertise and experience in the fields of pediatrics, pediatric emergency medicine, pediatric intensive care, neurosurgery and neuroradiology, as well as an experienced pediatric nurse and a parent representative were the components of the guidelines working group. Areas of direct interest included 1) initial assessment and stabilization in the ED, 2) diagnosis of clinically important traumatic brain injury in the ED, 3) management and disposition in the ED. The guidelines do not provide specific guidance on the identification and management of possible associated cervical spine injuries. Other exclusions are noted in the full text. CONCLUSIONS Recommendations to guide physicians practice when assessing children presenting to the ED following blunt head trauma are reported in both summary and extensive format in the guideline document.

Abstract
Biomarker-guided treatment is a rapidly developing area of medicine, where treatment choice is personalised according to one or more of an individual’s biomarker measurements. A number of biomarker-guided trial designs have been proposed in the past decade, including both adaptive and non-adaptive trial designs which test the effectiveness of a biomarker-guided approach to treatment with the aim of improving patient health. A better understanding of them is needed as challenges occur both in terms of trial design and analysis. We have undertaken a comprehensive literature review based on an in-depth search strategy with a view to providing the research community with clarity in definition, methodology and terminology of the various biomarker-guided trial designs (both adaptive and non-adaptive designs) from a total of 211 included papers. In the present paper, we focus on non-adaptive biomarker-guided trial designs for which we have identified five distinct main types mentioned in 100 papers. We have graphically displayed each non-adaptive trial design and provided an in-depth overview of their key characteristics. Substantial variability has been observed in terms of how trial designs are described and particularly in the terminology used by different authors. Our comprehensive review provides guidance for those designing biomarker-guided trials.

Abstract
AbstractObjectivesAssess the feasibility of a study evaluating one dose of oral ondansetron to decrease post-concussion symptoms at one week and one month following concussion in children aged 8 to 17 years old.MethodThis was a pilot study for a randomized, triple-blind controlled trial of one dose of either ondansetron or placebo performed in a tertiary care pediatric emergency department. Participants were children aged 8 to 17 years who sustained a concussion in the previous 24 hours and visited a single emergency department. The outcome of interest was an increase from pre-concussion baseline of at least 3 symptoms from the Post-Concussion Symptom Inventory, measured at one week and at one month following concussion. The primary outcome was to determine the proportion of children who completed the assessment at one week following the intervention. Secondary outcome was the proportion of children who completed the assessment at one month following the intervention. All children, care givers, and those assessing the outcomes were blinded to the group assignment.ResultsOf the 218 children presenting with a concussion during the study period, we screened 108 and found 36/108 (33%) eligible to participate and 16/108 (14.8%) agreed to participate. All enrolled patients were compliant with the intervention and follow-up.ConclusionIn our study population, approximately one-third of the screened concussion patients were eligible to participate and approximately one half of those eligible agreed to participate. Our study found that most enrolled patients preferred electronic follow-up; the noncompliance rate was minimal.

Abstract
BACKGROUND Reconfiguration of trauma services, with direct transport of traumatic brain injury (TBI) patients to neuroscience centres (NCs), bypassing non-specialist acute hospitals (NSAHs), could potentially improve outcomes. However, delays in stabilisation of airway, breathing and circulation (ABC) and the difficulties in reliably identifying TBI at scene may make this practice deleterious compared with selective secondary transfer from nearest NSAH to NC. National Institute for Health and Care Excellence guidance and systematic reviews suggested equipoise and poor-quality evidence - with regard to 'early neurosurgery' in this cohort - which we sought to address. METHODS Pilot cluster randomised controlled trial of bypass to NC conducted in two ambulance services with the ambulance station (n = 74) as unit of cluster [Lancashire/Cumbria in the North West Ambulance Service (NWAS) and the North East Ambulance Service (NEAS)]. Adult patients with signs of isolated TBI [Glasgow Coma Scale (GCS) score of < 13 in NWAS, GCS score of < 14 in NEAS] and stable ABC, injured nearest to a NSAH were transported either to that hospital (control clusters) or bypassed to the nearest NC (intervention clusters). PRIMARY OUTCOMES recruitment rate, protocol compliance, selection bias as a result of non-compliance, accuracy of paramedic TBI identification (overtriage of study inclusion criteria) and pathway acceptability to patients, families and staff. 'Open-label' secondary outcomes: 30-day mortality, 6-month Extended Glasgow Outcome Scale (GOSE) and European Quality of Life-5 Dimensions. RESULTS Overall, 56 clusters recruited 293 (169 intervention, 124 control) patients in 12 months, demonstrating cluster randomised pre-hospital trials as viable for heath service evaluations. Overall compliance was 62%, but 90% was achieved in the control arm and when face-to-face paramedic training was possible. Non-compliance appeared to be driven by proximity of the nearest hospital and perceptions of injury severity and so occurred more frequently in the intervention arm, in which the perceived time to the NC was greater and severity of injury was lower. Fewer than 25% of recruited patients had TBI on computed tomography scan (n = 70), with 7% (n = 20) requiring neurosurgery (craniotomy, craniectomy or intracranial pressure monitoring) but a further 18 requiring admission to an intensive care unit. An intention-to-treat analysis revealed the two trial arms to be equivalent in terms of age, GCS and severity of injury. No significant 30-day mortality differences were found (8.8% vs. 9.1/%; p > 0.05) in the 273 (159/113) patients with data available. There were no apparent differences in staff and patient preferences for either pathway, with satisfaction high with both. Very low responses to invitations to consent for follow-up in the large number of mild head injury-enrolled patients meant that only 20% of patients had 6-month outcomes. The trial-based economic evaluation could not focus on early neurosurgery because of these low numbers but instead investigated the comparative cost-effectiveness of bypass compared with selective secondary transfer for eligible patients at the scene of injury. CONCLUSIONS Current NHS England practice of bypassing patients with suspected TBI to neuroscience centres gives overtriage ratios of 13 : 1 for neurosurgery and 4 : 1 for TBI. This important finding makes studying the impact of bypass to facilitate early neurosurgery not plausible using this study design. Future research should explore an efficient comparative effectiveness design for evaluating 'early neurosurgery through bypass' and address the challenge of reliable TBI diagnosis at the scene of injury.

Abstract
BACKGROUND The management of minor and moderate head trauma in children differs widely between countries. Presently, there are no existing guidelines for management of these children in Scandinavia. The purpose of this study was to produce new evidence-based guidelines for the initial management of head trauma in the paediatric population in Scandinavia. The primary aim was to detect all children in need of neurosurgical intervention. Detection of any traumatic intracranial injury on CT scan was an important secondary aim. METHODS General methodology according to the Appraisal of Guidelines for Research and Evaluation (AGREE) II and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was used. Systematic evidence-based review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology and based upon relevant clinical questions with respect to patient-important outcomes. Quality ratings of the included studies were performed using Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 and Centre of Evidence Based Medicine (CEBM)-2 tools. Based upon the results, GRADE recommendations, a guideline, discharge instructions and in-hospital observation instructions were drafted. For elements with low evidence, a modified Delphi process was used for consensus, which included relevant clinical stakeholders. RESULTS The guidelines include criteria for selecting children for CT scans, in-hospital observation or early discharge, and suggestions for monitoring routines and discharge advice for children and guardians. The guidelines separate mild head trauma patients into high-, medium- and low-risk categories, favouring observation for mild, low-risk patients as an attempt to reduce CT scans in children. CONCLUSIONS We present new evidence and consensus based Scandinavian Neurotrauma Committee guidelines for initial management of minor and moderate head trauma in children. These guidelines should be validated before extensive clinical use and updated within four years due to rapid development of new diagnostic tools within paediatric neurotrauma.

Abstract
BACKGROUND Head injury represents an extremely common presentation to emergency departments (ED), but not all patients present immediately after injury. There is evidence that clinical deterioration following head injury will usually occur within 24 h. It is unclear whether this means that head injury patients that present in a delayed manner, especially after 24 h, have a lower prevalence of significant traumatic injuries including intra-cranial haemorrhages. METHODS A systematic review protocol was designed with the aim of systematically identifying and evaluating studies in delayed ED presentation head injury populations in order to establish whether the prevalence of significant intra-cranial injury was affected by delay in presentation. Two independent researchers assessed retrieved studies for inclusion against pre-determined inclusion criteria. Studies had to be conducted in ED head injury populations presenting in a delayed manner, and report a measure of prevalence of traumatic CT abnormality as an outcome. RESULTS Three studies were eligible for inclusion. They were all of poor methodological quality, and heterogeneity prevented meta-analysis. The reported prevalence of traumatic intra-cranial injury on CT was between 2.2 and 6.3%. This is generally lower than reported in the literature for non-delayed presentation head injury populations. CONCLUSIONS Available evidence suggests that head injury patients who present in a delayed fashion to the ED may have lower rates of intra-cranial injury compared to non-delayed head injury patients. However, the evidence is sparse and it is of too low quality to guide clinical practice. Further research is required to help the clinical risk assessment of this group.

Abstract
INTRODUCTION The objective of this study was to compare long-term neurological outcomes in low-risk patients with traumatic intracranial hemorrhage (tICH) admitted to the ICU (intensive care unit) versus patients admitted to the floor. METHODS This retrospective study was conducted at a Level 1 trauma center from October 1, 2008, to February 1, 2013. We defined low-risk patients as age less than 65 years, isolated head injury, normal admission mental status, and no shift or swelling on initial head CT (computed tomography). Clinical data were abstracted from a trauma registry and linked to a brain injury database. We compared the Extended Glasgow Outcome Scale (GOS-E) score at six months between patients admitted to the ICU and patients admitted to the floor. We did a risk-adjusted analysis of the influence of floor admission on a normal GOS-E. RESULTS We identified 151 patients; 45 (30%) were admitted to the floor and 106 (70%) to the ICU. Twenty-three (51%; 95% CI [36-66%]) patients admitted to the floor and 55 (52%; 95% CI [42-62%]) patients admitted to the ICU had a normal GOS-E. On adjusted analysis; the odds ratio for floor admission was 0.77 (95% CI [0.36-1.64]) for a normal GOS-E at six months. CONCLUSION Long-term neurological outcomes in low-risk patients with tICH were not markedly different between patients admitted to the ICU and those admitted to the floor. However, we were unable to demonstrate non-inferiority on adjusted analysis. Future work aimed at a larger, prospective cohort may better evaluate the relative impacts of admission type on outcomes.

Abstract
OBJECTIVE The main objective of this study was to evaluate the incidence of delayed complications in acute head injury (HI) patients with an initial normal head computed tomography (CT). MATERIALS AND METHODS This retrospective study included 3023 consecutive patients who underwent head CT due to an acute HI at the Emergency Department (ED) of Tampere University Hospital (August 2010-July 2012). Regardless of clinical injury severity, the patients with a normal head CT were selected (n=2444, 80.9%). The medical records of these patients were reviewed to identify the individuals with a serious clinically significant complication related to the primary HI. The time window considered was the following 72h after the primary head CT. A repeated head CT in the hospital ward, death, or return to the ED were indicative of a possible complication. RESULTS The majority (n=1811, 74.1%) of the patients with a negative head CT were discharged home and 1.1% (n=27) of these patients returned to ED within 72h post-CT. A repeated head CT was performed on 12 (44.4%) of the returned patients and none of the scans revealed an acute lesion. Of the 632 (25.9%) CT-negative patients admitted to the hospital ward from the ED, a head CT was repeated in 46 (7.3%) patients within 72h as part of routine practice. In the repeated CT sample, only one (0.2%) patient had a traumatic intracranial lesion. This lesion did not need neurosurgical intervention. The overall complication rate was 0.04%. CONCLUSION In the present study, which includes head injuries of all severity, the probability of delayed life-threatening complications was negligible when the primary CT scan revealed no acute traumatic lesions.

Abstract
Objectives: The aim of this study was to analyze whether health technology assessment (HTA) reports published by SBU have influenced decisions, guidelines, clinical practice, or research priorities in Sweden.Methods: All twenty-six SBU reports between 2006 and 2010 were analyzed. For each project, we searched publications and documentation that reflected impact on decisions, guidelines, research or clinical practice. Written documentation, before–after surveys or register-based time series data were used when available. Based on a conceptual model and on the available evidence, we determined whether HTA reports had a high, moderate, or low impact.Results: HTA reports influenced comprehensive decisions to a high or moderate degree. In the case of fortifying flour with folic acid to a high degree. In ten cases, HTA reports were the primary source of clinical guidelines developed by the National Board of Health and Welfare (NBHW) or professional associations. In the cases of dyspepsia and gastro-esophageal reflux, as well as mild head injury, the HTA reports had a high impact on clinical practice. It was also obvious from this review that research had been initiated as a result of the knowledge gaps identified by HTA reports. In three cases, we had no adequate documentation, suggesting that the impact of the HTA report had been low.Conclusions: Many interrelated forces change practice, but the cases presented here indicate that HTA reports have had a high impact on clinical guidelines, as well as a moderate or high impact on comprehensive decisions, the initiation of research and changes in clinical practice.

[PMID: 24581911 DOI: 10.1016/j.apmr.2013.10.009] [Citation(s) in RCA: 58] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2013] [Revised: 10/11/2013] [Accepted: 10/23/2013] [Indexed: 11/17/2022]
Abstract
OBJECTIVE To synthesize the best available evidence regarding the impact of nonsurgical interventions on persistent symptoms after mild traumatic brain injury (MTBI). DATA SOURCES MEDLINE and other databases were searched (2001-2012) with terms including "rehabilitation." Inclusion criteria were original, peer-reviewed research published in English and other languages. References were also identified from the bibliographies of eligible articles. STUDY SELECTION Controlled trials and cohort and case-control studies were selected according to predefined criteria. Studies had to have a minimum of 30 MTBI cases and assess nonsurgical interventions using clinically relevant outcomes such as self-rated recovery. DATA EXTRACTION Eligible studies were critically appraised using a modification of the Scottish Intercollegiate Guidelines Network (SIGN) criteria. Two reviewers independently reviewed each study and extracted data from the admissible studies into evidence tables. DATA SYNTHESIS The evidence was synthesized qualitatively according to the modified SIGN criteria. Recommendations were linked to the evidence tables using a best-evidence synthesis. After 77,914 records were screened, only 2 of 7 studies related to nonsurgical interventions were found to have a low risk of bias. One studied the effect of a scheduled telephone intervention offering counseling and education on outcome and found a significantly better outcome for symptoms (6.6 difference in adjusted mean symptom score; 95% confidence interval, 1.2-12.0), but no difference in general health outcome at 6 months after MTBI. The other was a randomized controlled trial of the effectiveness of 6 days of bed rest on posttraumatic complaints 6 months postinjury, compared with no bed rest, and found no effect. CONCLUSIONS Some evidence suggests that early, reassuring educational information is beneficial after MTBI. Well-designed intervention studies are required to develop effective treatments and improve outcomes for adults and children at risk for persistent symptoms after MTBI.

Abstract
OBJECTIVES To investigate present established routines and standards in managing minor head-injured children in Danish hospitals, a survey of present management practice was conducted. MATERIALS AND METHODS A cross-sectional mail survey, detailing clinical and radiological examinations, in-hospital observation, discharge criteria and follow-up, was performed on all 46 hospitals treating children with minor head injury in Denmark. RESULTS Of the 46 hospitals, 33% report having established written criteria for the referral and management of children with minor head injury. Ten (22%) of the 46 hospitals are so-called injury clinics, where only nurses are employed. All state that they use the Glasgow Coma Scale (GCS) and/or the paediatric GCS to assess the level of consciousness; 15% use the paediatric GCS exclusively. None perform routine radiological examinations. Criteria for early discharge are established in 98% of the hospitals. All hospitals provide written instructions for observations at home before discharge. CONCLUSION The management of children with minor head injury varies between hospitals in Denmark. Local management guidelines are either lacking or mainly based on those of adults. Hence, there is a need for the development of minor head injury guidelines specifically designed for the management of children.

Abstract
BACKGROUND Most patients who sustain mild traumatic brain injury (mTBI) have persistent symptoms at 1 week and 1 month after injury. This systematic review investigated the effectiveness of interventions initiated in acute settings for patients who experience mTBI. METHODS We performed a systematic review of all randomized clinical trials evaluating any intervention initiated in an acute setting for patients experiencing acute mTBI. All possible outcomes were included. The primary sources of identification were MEDLINE, Embase, PsycINFO, CINAHL, and the Cochrane Central register of Controlled Trials, from 1980 to August 2012. Hand searching of proceedings from five meetings related to mTBI was also performed. Study selection was conducted by two co-authors, and data abstraction was completed by a research assistant specialized in conducting systematic reviews. Study quality was evaluated using Cochrane's Risk of Bias assessment tool. RESULTS From a potential 15,156 studies, 1,268 abstracts were evaluated and 120 articles were read completely. Of these, 15 studies fulfilled the inclusion/exclusion criteria. One study evaluated a pharmacological intervention, two evaluated activity restriction, one evaluated head computed tomography scan versus admission, four evaluated information interventions, and seven evaluated different follow-up interventions. Use of different outcome measures limited the possibilities for analysis. However, a meta-analysis of three studies evaluating various follow-up strategies versus routine follow-up or no follow-up failed to show any effect on three outcomes at 6 to 12 months post-trauma. In addition, a meta-analysis of two studies found no effect of an information intervention on headache at 3 months post-injury. CONCLUSIONS There is a paucity of well-designed clinical studies for patients who sustain mTBI. The large variability in outcomes measured in studies limits comparison between them.

Abstract
OBJECTIVE The objectives of this study were to determine which method of head injury evaluation, immediate computed tomography (CT) or observation, parents would prefer for their child when given the opportunity to make an informed decision and to determine factors influencing preference. METHODS Parents of head-injured children 2 years or older who presented to a pediatric emergency department were eligible. After triage evaluation, and before physician assessment, research assistants presented educational materials regarding the method, risks, and benefits of both immediate CT and observation. Parents then completed a survey asking them their preference, reasons for preference, details of their child's injury, and demographic information. RESULTS One hundred thirty-four parents participated. After reviewing the educational materials, 53 (40%) preferred immediate CT; 77 (57%) preferred observation; 4 (3%) did not indicate a preference. Of those parents who preferred immediate CT, the leading reason given was, "I need to be 100% sure there is no bleeding in my child's brain." Of those parents who preferred observation, the 2 leading reasons given were, "I don't want my child to have a test unless he/she absolutely has to" and "I am concerned about the possibility of radiation causing a brain tumor." Injury mechanism, time between injury and presentation, time of day, child's age, worst symptom, previous CT, and demographic markers were not statistically associated with preference. CONCLUSIONS When given the opportunity to make an informed decision regarding the evaluation of their head-injured child, parents were divided as to their preference. A small majority preferred observation.

Abstract
Background This study prospectively assesses clinical characteristics and management of consecutive minimal, mild and moderate head injury patients referred for CT scans. Compliance with the Scandinavian head injury guidelines and possible reasons for non-compliance is explored. Methods From January 16th 2006 to January 15th 2007, 1325 computed tomography (CT) examinations due to minimal, mild or moderate head injury according to the Head Injury Severity Scale (HISS) were carried out at our University Hospital. When ordering a CT scan due to head trauma, physicians were asked to fill out a questionnaire. Results Guideline compliance was impossible to assess in 49.5% of all cases. This was due to non-assessable or missing key variables necessary in the decision making algorithm. One or more key variables for HISS classification were not assessable in 34.4% as it was unknown whether there had been loss of consciousness (LOC), duration of LOC was unknown or it was impossible to assess amnesia or focal neurologic deficits. Definite compliance with both CT and admittance recommendations in guidelines was seen in only 31.2%. In 54.2% of patients with minimal head injuries who underwent CT scans, imaging was not necessary according to guidelines. 59.1% of all patients were admitted to hospital, however only 23.7% of these were admitted because of the head-injury alone. Age < 4 years, possible medical cause of injuries, severe headache/nausea or vomiting and the presence of non-traumatic CT findings were independently associated with non-assessable compliance with Scandinavian guidelines. Suspicion of influence of alcohol was inversely associated to non-compliance. Conclusions Despite the prospective study design, guideline compliance was not assessable in nearly half of the patients. Patients with isolated head injuries and available and obtainable complete clinical information necessary for guideline-based decision making are not dominating in a head injury population.

Abstract
BACKGROUND Current recommendations are that young children with a skull fracture following head injury undergo computed tomography (CT) examination of their head to exclude significant intracranial injury. Recent reports, however, have raised concern that radiation exposure from CT scanning may cause malignancies. OBJECTIVE To estimate the proportion of children with nondisplaced linear skull fractures who have clinically significant intracranial injury. METHODS Retrospective review of patients younger than 2 years who presented to an emergency department and received a diagnosis of skull fracture. RESULTS Ninety-two patients met the criteria for inclusion in the study; all had a head CT scan performed. None suffered a clinically significant intracranial injury. CONCLUSION Observation, rather than CT, may be a reasonable management option for head-injured children younger than 2 years who have a nondisplaced linear skull fracture on plain radiography but no clinical signs of intracranial injury.

Abstract
BACKGROUND AND PURPOSE More evidence is needed to forward our understanding of the key determinants of poor outcome after mild traumatic brain injury (MTBI). A large, prospective, national cohort of patients was studied to analyse the effect of head CT scan pathology on the outcome. METHODS One-thousand two-hundred and sixty-two patients with MTBI (Glasgow Coma Scale score 15) at 39 emergency departments completed a study protocol including acute head CT scan examination and follow-up by the Rivermead Post Concussion Symptoms Questionnaire and the Glasgow Outcome Scale Extended (GOSE) at 3 months after MTBI. Binary logistic regression was used for the assessment of prediction ability. RESULTS In 751 men (60%) and 511 women (40%), with a mean age of 30 years (median 21, range 6-94), we observed relevant or suspect relevant pathologic findings on acute CT scan in 52 patients (4%). Patients aged below 30 years reported better outcome both with respect to symptoms and GOSE as compared to patients in older age groups. Men reported better outcome than women as regards symptoms (OR 0.64, CI 0.49-0.85 for ≥3 symptoms) and global function (OR 0.60, CI 0.39-0.92 for GOSE 1-6). CONCLUSIONS Pathology on acute CT scan examination had no effect on self-reported symptoms or global function at 3 months after MTBI. Female gender and older age predicted a less favourable outcome. The findings support the view that other factors than brain injury deserve attention to minimize long-term complaints after MTBI.

Abstract
Traumatic Brain Injury (TBI) is among the most frequent neurological disorders. Of all TBIs 90% are considered mild with an annual incidence of 100–300/100.000. Intracranial complications of Mild Traumatic Brain Injury (MTBI) are infrequent (10%), requiring neurosurgical intervention in a minority of cases (1%), but potentially life-threatening (case fatality rate 0,1%). Hence, a true health management problem exists because of the need to exclude the small chance of a life threatening complication in large numbers of individual patients. The 2002 EFNS guidelines used a best evidence approach based on the literature until 2001 to guide initial management with respect to indications for CT, hospital admission, observation and follow up of MTBI patients. This updated EFNS guideline version for initial management inMTBI proposes a more selectively strategy for CT when major (dangerous mechanism, GCS<15, 2 points deterioration on the GCS, clinical signs of (basal) skull fracture, vomiting, anticoagulation therapy, post traumatic seizure) or minor (age, loss of consciousness, persistent anterograde amnesia, focal deficit, skull contusion, deterioration on the GCS) risk factors are present based on published decision rules with a high level of evidence. In addition clinical decision rules for CT now exist for children as well. Since 2001 recommendations, although with a lower level of evidence, have been published for clinical in hospital observation to prevent and treat other potential threads to the patient including behavioral disturbances (amnesia, confusion and agitation) and infection.

Abstract
OBJECTIVES This study was aimed to assess whether serum S100B levels at emergency department admission can be used to omit unnecessary computed tomography (CT) in patients with minor head injury (MHI). DESIGN AND METHODS Sixty consecutive patients with recent MHI were included in this study. Serum S100B measurement and CT scanning were performed in all patients within 3h from head injury. RESULTS A positive CT scan was present in 20 out of 60 subjects. Significantly higher values of protein S100B were found in CT positive than in CT negative patients (1.35 versus 0.48 μg/L; p<0.001). The area under the ROC curve for protein S100B was highly significant (AUC 0.80; p<0.001) and a S100B cut-off value of 0.38 μg/L displayed 100% sensitivity and 58% specificity. CONCLUSIONS Serum S100-B levels might allow to omit unnecessary CT in patients with pure MHI, thus reducing radiation exposure and saving healthcare resources.

Abstract
BACKGROUND Detecting patients at risk for secondary neurological deterioration (SND) after mild to moderate traumatic brain injury is challenging. OBJECTIVE To assess the diagnostic accuracy of transcranial Doppler (TCD) on admission in screening these patients. METHODS This prospective, observational cohort study enrolled 98 traumatic brain injury patients with an initial Glasgow Coma Scale score of 9 to 15 whose initial computed tomography (CT) scan showed either absent or mild lesions according to the Trauma Coma Data Bank (TCDB) classification, ie, TCDB I and TCDB II, respectively. TCD measurements of the 2 middle cerebral arteries were obtained on admission under stable conditions in all patients. Neurological outcome was reassessed on day 7. RESULTS Of the 98 patients, 21 showed SND, ie, a decrease of ≥ 2 points from the initial Glasgow Coma Scale or requiring any treatment for neurological deterioration. Diastolic cerebral blood flow velocities and pulsatility index measurements were different between patients with SND and patients with no SND. Using receiver-operating characteristic analysis, we found the best threshold limits to be 25 cm/s (sensitivity, 92%; specificity, 76%; area under curve, 0.93) for diastolic cerebral blood flow velocity and 1.25 (sensitivity, 90%; specificity, 91%; area under curve, 0.95) for pulsatility index. According to a recursive-partitioning analysis, TCDB classification and TCD measurements were the most discriminative among variables to detect patients at risk for SND. CONCLUSION In patients with no severe brain lesions on CT after mild to moderate traumatic brain injury, TCD on admission, in complement with brain CT scan, could accurately screen patients at risk for SND.

Abstract
Mild traumatic brain injury (mTBI) is the commonest form of TBI. Though the name implies, it may not be mild in certain cases. There is a lot of heterogeneity in nomenclature, classification, evaluation and outcome of mTBI. We have reviewed the relevant articles on mTBI in adults, particularly its definition, evaluation and outcome, published in the last decade. The aspects of mTBI like pediatric age group, sports concussion, and postconcussion syndrome were not reviewed. There is general agreement that Glasgow coma score (GCS) of 13 should not be considered as mTBI as the risk of intracranial lesion is higher than in patients with GCS 14-15. All patients with GCS of <15 should be evaluated with a computed tomography (CT) scan. Patients with GCS 15 and risk factors or neurological symptoms should also be evaluated with CT scan. The outcome of mTBI depends on the combination of preinjury, injury and postinjury factors. Overall outcome of mTBI is good with mortality around 0.1% and disability around 10%.

Abstract
BACKGROUND Patients with traumatic brain injury (TBI) and traumatic intracranial hemorrhage are frequently admitted to the intensive care unit (ICU) but never require critical care interventions. Improved ICU triage in this patient population can improve resource utilization and decrease health care costs. We sought to identify a low-risk group of patients with TBI who do not require admission to an ICU. METHODS This is a retrospective cohort study of adult patients with TBI and traumatic intracranial hemorrhage. The need for ICU admission was defined as the presence of a critical care intervention. Patients were considered low risk if there was no critical care intervention before hospital admission. Measured outcomes included delayed critical care interventions at 48 hours and during hospitalization, mortality, and emergency surgery. RESULTS A total of 187 of 320 patients were considered low risk. In the low-risk group, two patients (1.1%; 95% confidence interval [CI], 0.1-3.8) had a delayed critical care intervention within 48 hours of admission and four patients (2.1%; 95% CI, 0.6-5.4) after 48 hours of admission. Two patients (1.1%; 95% CI, 0-3.8) in the low-risk group died. No patients in the low-risk group required neurosurgical intervention. CONCLUSION Patients with TBI without a critical care intervention before admission are at low risk for requiring future critical care interventions. Future studies are required to validate if this low-risk criteria can serve as a safe, cost-effective triage tool for ICU admission.

Abstract
STUDY OBJECTIVE A computed tomography (CT) scan has high sensitivity in detecting intracranial injury in patients with minor head injury but is costly, exposes patients to high radiation doses, and reveals clinically relevant lesions in less than 10% of cases. We evaluate S100-B protein measurement as a screening tool in a large population of patients with minor head injury. METHODS We conducted a prospective observational study in the emergency department of a teaching hospital (Bordeaux, France). Patients with minor head injury (2,128) were consecutively included from December 2007 to February 2009. CT scans and plasma S100-B levels were compared for 1,560 patients. The main outcome was to evaluate the diagnostic value of the S100-B test, focusing on the negative predictive value and the negative likelihood ratio. RESULTS CT scan revealed intracranial lesions in 111 (7%) participants, and their median S100-B protein plasma level was 0.46 μg/L (interquartile range [IQR] 0.27 to 0.72) versus 0.22 μg/L (IQR 0.14 to 0.36) in the other 1,449 patients. With a cutoff of 0.12 μg/L, traumatic brain injuries on CT were identified with a sensitivity of 99.1% (95% confidence interval [CI] 95.0% to 100%), a specificity of 19.7% (95% CI 17.7% to 21.9%), a negative predictive value of 99.7% (95% CI 98.1% to 100%), a positive likelihood ratio of 1.24 (95% CI 1.20 to 1.28), and a negative likelihood ratio of 0.04 (95% CI 0.006 to 0.32). CONCLUSION Measurement of plasma S100-B on admission of patients with minor head injury is a promising screening tool that may be of help to support the clinician's decision not to perform CT imaging in certain cases of low-risk head injury.

Abstract
Mild head trauma had been defined in patients with direct impact or deceleration effect admitted with a Glasgow Coma Scale score of 13-15. It is one of the most frequent causes of morbidity in emergency medicine. Although common, several controversies persist about its clinical management. In this paper, we describe the Brazilian guidelines for mild head trauma, based on a critical review of the relevant literature.

Abstract
AIMS To compare the yield of positive computed tomography (CT) brain examinations after the implementation of the National Institute for Clinical Excellence (NICE) or the Scottish Intercollegiate Guidance Network (SIGN) guidelines, in comparable urban populations in two teaching hospitals in England and Scotland. MATERIALS AND METHODS Four hundred consecutive patients presenting at each location following a head injury who underwent a CT examination of the head according to the locally implemented guidelines were compared. Similar matched populations were compared for indication and yield. Yield was measured according to (1) positive CT findings of the sequelae of trauma and (2) intervention required with anaesthetic or intensive care unit (ICU) support, or neurosurgery. RESULTS The mean ages of patients at the English and Scottish centres were 49.9 and 49.2 years, respectively. Sex distribution was 64.1% male and 66.4% male respectively. Comparative yield was 23.8 and 26.5% for positive brain scans, 3 and 2.75% for anaesthetic support, and 3.75 and 2.5% for neurosurgical intervention. Glasgow Coma Score (GCS) <13 (NICE) and GCS ≤ 12 and radiological or clinical evidence of skull fracture (SIGN) demonstrated the greatest statistical association with a positive CT examination. CONCLUSION In a teaching hospital setting, there is no significant difference in the yield between the NICE and SIGN guidelines. Both meet the SIGN standard of >10% yield of positive scans. The choice of guideline to follow should be at the discretion of the local institution. The indications GCS <13 and clinical or radiological evidence of a skull fracture are highly predictive of intracranial pathology, and their presence should be an absolute indicator for fast-tracking the management of the patient.

Abstract
The definition of a mild traumatic brain injury (TBI) has come under close scrutiny and is changing as a result of refined diagnostic testing. Although up to 15% of patients with a mild TBI will have an acute intracranial lesion identified on head computed tomography (CT), less than 1% of these patients will have a lesion requiring a neurosurgical intervention. Evidence-based guideline methodology has assisted in generating recommendations to facilitate clinical decision making; however, no set of guidelines is 100% sensitive and specific. Evidence supports the safety of discharging patients with mild TBI who have a negative CT. However, though patients with a negative CT are at almost no risk of deteriorating from a neurosurgical lesion, a key intervention is to provide these patients at discharge from the emergency department with counseling regarding postconcussive symptoms, when to return to work, school, or sports, and when to seek additional medical care.

Can low serum levels of S100B predict normal CT findings after minor head injury in adults?: an evidence-based review and meta-analysis. J Head Trauma Rehabil 2010; 25:228-40.

Abstract
OBJECTIVE To determine whether low levels of S100B in serum can predict normal computed tomography (CT) findings after minor head injury (MHI) in adults. PARTICIPANTS Not applicable. DESIGN Systematic evidence-based review of the peer-reviewed literature with meta-analytical interpretation. PRIMARY MEASURES Not applicable. RESULTS We identified 12 eligible articles that specifically studied adult MHI patients with S100B and cranial CT scans in the acute phase after injury, comprising a total of 2466 separate patients. Individual negative predictive values of 90% to 100% were found for the ability of a negative (under cutoff) S100B level to predict a normal CT scan. A total of 6 patients included in the studies had low S100B levels and positive CT scans (0.26%) and only 1 of these patients (0.04%) had a clinically relevant CT finding. The pooled negative predictive value for all studies was more than 99% (95% CI 98%-100%), with an average prevalence for any CT finding at 8%. The studies are consistently classed as level 2 and level 3 grades of evidence, suggesting a grade B recommendation. CONCLUSION Low serum S100B levels accurately predict normal CT findings after MHI in adults. S100B sampling should be considered in MHI patients with no focal neurological deficit, an absence of significant extracerebral injury, should be taken within 3 hours of injury, and the cutoff for omitting CT set at less than 0.10 microg/L. Care givers should also be aware of other clinical factors predictive of intracranial complications after MHI.

Abstract
Mild traumatic brain injury (mTBI) is a common heterogeneous neurological disorder with a wide range of possible clinical outcomes. Accurate prediction of outcome is desirable for optimal treatment. This study aimed both to identify the demographic, clinical, and computed tomographic (CT) characteristics associated with unfavorable outcome at 6 months after mTBI, and to design a prediction model for application in daily practice. All consecutive mTBI patients (Glasgow Coma Scale [GCS] score: 13-15) admitted to our hospital who were age 16 or older were included during an 8-year period as part of the prospective Radboud University Brain Injury Cohort Study (RUBICS). Outcome was assessed at 6 months post-trauma using the Glasgow Outcome Scale-Extended (GOSE), dichotomized into unfavorable (GOSE score 1-6) and favorable (GOSE score 7-8) outcome groups. The predictive value of several variables was determined using multivariate binary logistic regression analysis. We included 2784 mTBI patients and found CT abnormalities in 20.7% of the 1999 patients that underwent a head CT. Age, extracranial injuries, and day-of-injury alcohol intoxication proved to be the strongest outcome predictors. The presence of facial fractures and the number of hemorrhagic contusions emerged as CT predictors. Furthermore, we showed that the predictive value of a scheme based on a modified Injury Severity Score (ISS), alcohol intoxication, and age equalled the value of one that also included CT characteristics. In fact, it exceeded one that was based on CT characteristics alone. We conclude that, although valuable for the identification of the individual mTBI patient at risk for deterioration and eventual neurosurgical intervention, CT characteristics are imperfect predictors of outcome after mTBI.

Abstract
In most instances, infants and children with moderate to severe head trauma undergo a head computed tomography (CT) scan as part of their initial evaluation. Several authors have advocated a routine second head CT after traumatic brain injury (TBI) to identify progressive lesions that may require surgical intervention. However, recent studies have challenged the need for a routine second brain imaging study after TBI. In addition, recent reports have raised concerns about the potential for malignancy following CT scanning, especially in pediatric patients. The authors performed a retrospective case series of all patients, aged 0 to 21 years, who presented to their 2 emergency departments (EDs) and received an International Classification of Disease-9th revision code related to intracranial injury. Out of 47 children, 5 (11%) underwent neurosurgical intervention following their second imaging study, and 1 of these interventions was unplanned after the first study. Compared with children who did not require an intervention following their second scan, children who received an intervention were more likely to have been subjected to nonaccidental trauma and to have presented to the ED more than 4 hours after the injury. Most children with intracranial injury following blunt trauma who did not require immediate neurosurgical intervention but instead underwent a follow-up brain imaging study did not require subsequent unplanned neurosurgical intervention. Serial brain imaging may not be required for all children with intracranial injury.

Abstract
Background Decisions about interim analysis and early stopping of clinical trials, as based on recommendations of Data Monitoring Committees (DMCs), have far reaching consequences for the scientific validity and clinical impact of a trial. Our aim was to evaluate the frequency and quality of the reporting on DMC composition and roles, interim analysis and early termination in pediatric trials. Methods We conducted a systematic review of randomized controlled clinical trials published from 2005 to 2007 in a sample of four general and four pediatric journals. We used full-text databases to identify trials which reported on DMCs, interim analysis or early termination, and included children or adolescents. Information was extracted on general trial characteristics, risk of bias, and a set of parameters regarding DMC composition and roles, interim analysis and early termination. Results 110 of the 648 pediatric trials in this sample (17%) reported on DMC or interim analysis or early stopping, and were included; 68 from general and 42 from pediatric journals. The presence of DMCs was reported in 89 of the 110 included trials (81%); 62 papers, including 46 of the 89 that reported on DMCs (52%), also presented information about interim analysis. No paper adequately reported all DMC parameters, and nine (15%) reported all interim analysis details. Of 32 trials which terminated early, 22 (69%) did not report predefined stopping guidelines and 15 (47%) did not provide information on statistical monitoring methods. Conclusions Reporting on DMC composition and roles, on interim analysis results and on early termination of pediatric trials is incomplete and heterogeneous. We propose a minimal set of reporting parameters that will allow the reader to assess the validity of trial results.

Abstract
Minor head injury is a frequent cause for neurologic consultation and imaging. Most patients with minor head injury will make an uneventful recovery, but in a very small proportion of these patients life threatening intracranial complications occur. We describe a patient on oral anticoagulation therapy, and severely impaired coagulation, with normal head computed tomography on admission, who developed a subdural hematoma requiring surgery 12 hours later. Current guidelines and literature for the management of minor head injury are discussed.

Abstract
This clinical policy provides evidence-based recommendations on select issues in the management of adult patients with mild traumatic brain injury (TBI) in the acute setting. It is the result of joint efforts between the American College of Emergency Physicians and the Centers for Disease Control and Prevention and was developed by a multidisciplinary panel. The critical questions addressed in this clinical policy are: (1) Which patients with mild TBI should have a noncontrast head computed tomography (CT) scan in the emergency department (ED)? (2) Is there a role for head magnetic resonance imaging over noncontrast CT in the ED evaluation of a patient with acute mild TBI? (3) In patients with mild TBI, are brain specific serum biomarkers predictive of an acute traumatic intracranial injury? (4) Can a patient with an isolated mild TBI and a normal neurologic evaluation result be safely discharged from the ED if a noncontrast head CT scan shows no evidence of intracranial injury? Inclusion criteria for application of this clinical policy's recommendations are nonpenetrating trauma to the head, presentation to the ED within 24 hours of injury, a Glasgow Coma Scale score of 14 or 15 on initial evaluation in the ED, and aged 16 years or greater. The primary outcome measure for questions 1, 2, and 3 is the presence of an acute intracranial injury on noncontrast head CT scan; the primary outcome measure for question 4 is the occurrence of neurologic deterioration.
