RESUMO
OBJECTIVE: The aim of this study was to compare injury circumstances, characteristics, and clinical management of emergency department (ED) presentations for sports-related concussion (SRC) and non-SRC. METHODS: This multicenter prospective observational study identified patients 5-17 years old who presented to EDs within 24 hours of head injury, with one or more signs or symptoms of concussion. Participants had a Glasgow Coma Scale score of 13-15 and no abnormalities on CT (if performed). Data were stratified by age: young children (5-8 years), older children (9-12 years), and adolescents (13-17 years). RESULTS: Of 4709 patients meeting the concussion criteria, non-SRC accounted for 56.3% of overall concussions, including 80.9% of younger child, 51.1% of older child, and 37.0% of adolescent concussions. The most common mechanism of non-SRC was falls for all ages. The most common activity accounting for SRC was bike riding for younger children, and rugby for older children and adolescents. Concussions occurring in sports areas, home, and educational settings accounted for 26.2%, 21.8%, and 19.0% of overall concussions. Concussions occurring in a sports area increased with age, while occurrences in home and educational settings decreased with age. The presence of amnesia significantly differed for SRC and non-SRC for all age groups, while vomiting and disorientation differed for older children and adolescents. Adolescents with non-SRC were admitted to a ward and underwent CT at higher proportions than those with SRC. CONCLUSIONS: Non-SRC more commonly presented to EDs overall, with SRC more common with increasing age. These data provide important information to inform public health policies, guidelines, and prevention efforts.

AIM: Paediatric head injuries (PHI) are the most common cause of trauma-related emergency department (ED) presentations. This study sought to report the incidence of PHI in Australia, examine the temporal trends from 2014 to 2018 and estimate the patient and population-level acute care costs. METHODS: Taking a public-sector health-care perspective, we applied direct and indirect hospital costs for PHI-related ED visits and acute admissions. All costs were inflated to 2018 Australian dollars ($). The patient-level analysis was performed with data from 17 841 children <18 years old enrolled in the prospective Australasian Paediatric Head Injury Study. Mechanisms of injury were characterised by the total and average acute care costs. The population-level data of PHI-related ED presentations were obtained from the Independent Hospital Pricing Authority. Age-standardised incidence rates (IR) and incidence rate ratios (IRR) were calculated, and negative binomial regression examined the temporal trend. RESULTS: The age-standardised IR for PHI was 2734 per 100 000 population in 2018, with a significant increase over 5 years (IRR 1.13, 95% confidence interval (CI) 1.12-1.14; P < 0.001) and acute care costs of $154 million. Falls occurred in 70% of the study cohort, with average costs per episode of $666 (95% CI: $627-$706), accounting for 47% of acute care costs. Transportation-related injuries occurred in 4.1% of the study cohort, with average costs per episode of $8555 (95% CI: $6193-$10 917), accounting for 35% of acute care costs. CONCLUSION: PHI have increased significantly in Australia and are associated with substantial acute care costs. Population-based efforts are required for road safety and injury prevention.

BACKGROUND: Airway management procedures are critical for emergency medicine (EM) physicians, but rarely performed skills in pediatric patients. Worldwide experience with respect to frequency and confidence in performing airway management skills has not been previously described. OBJECTIVES: Our aims were 1) to determine the frequency with which emergency medicine physicians perform airway procedures including: bag-mask ventilation (BMV), endotracheal intubation (ETI), laryngeal mask airway (LMA) insertion, tracheostomy tube change (TTC), and surgical airways, and 2) to investigate predictors of procedural confidence regarding advanced airway management in children. METHODS: A web-based survey of senior emergency physicians was distributed through the six research networks associated with Pediatric Emergency Research Network (PERN). Senior physician was defined as anyone working without direct supervision at any point in a 24-h cycle. Physicians were queried regarding their most recent clinical experience performing or supervising airway procedures, as well as with hands on practice time or procedural teaching. Reponses were dichotomized to within the last year, or ≥ 1 year. Confidence was assessed using a Likert scale for each procedure, with results for ETI and LMA stratified by age. Response levels were dichotomized to "not confident" or "confident." Multivariate regression models were used to assess relevant associations. RESULTS: 1602 of 2446 (65%) eligible clinicians at 96 PERN sites responded. In the previous year, 1297 (85%) physicians reported having performed bag-mask ventilation, 900 (59%) had performed intubation, 248 (17%) had placed a laryngeal mask airway, 348 (23%) had changed a tracheostomy tube, and 18 (1%) had performed a surgical airway. Of respondents, 13% of physicians reported the opportunity to supervise but not provide ETI, 5% for LMA and 5% for BMV. The percentage of physicians reporting "confidence" in performing each procedure was: BMV (95%) TTC (43%), and surgical airway (16%). Clinician confidence in ETT and LMA varied by patient age. Supervision of an airway procedure was the strongest predictor of procedural confidence across airway procedures. CONCLUSION: BMV and ETI were the most commonly performed pediatric airway procedures by emergency medicine physicians, and surgical airways are very infrequent. Supervising airway procedures may serve to maintain procedural confidence for physicians despite infrequent opportunities as the primary proceduralist.

BACKGROUND: Undifferentiated abdominal pain is a common pediatric presentation to the emergency department (ED). OBJECTIVES: The objective of this study was to describe the prevalence of clinically significant abdominal pathology (CSAP) including appendicitis, patterns of imaging and pathology tests, and management and outcomes of children with abdominal pain in ED. METHODS: A prospective multicenter observational cohort pilot study of children under the age of 16 years presenting to 4 Australian EDs with abdominal pain was performed for a 1-month period at each site. The primary outcome was to describe the prevalence of CSAP and appendicitis. Age, sex, length of stay, surgery or interventional procedure, investigations, and analgesia use were recorded. RESULTS: There were 555 presentations with abdominal pain during the study period with a median age of 9 years (interquartile range, 6-12 years). Eighty-two patients (14.8%; 95% confidence interval, 11.8-17.7) had CSAP, of which 41 (7.4%, 5.2-9.6) had appendicitis. Three hundred forty-eight (62.7%, 58.7-66.7) were discharged directly from ED, and 207 (37.3%, 33.2-41.3) were admitted. Two hundred fifty-five (45.9%, 41.8-50.1) had pathology tests, and 173 (31.2%, 27.3-35.1) had imaging tests in ED. Of those contacted for telephone follow-up, 100 (50.5%, 43.5-57.5) of 198 reported ongoing pain after discharge, and 13.1% (8.4-17.8) had missed over a week of school due to abdominal pain. CONCLUSIONS: The prevalence of CSAP and appendicitis in our study was 14.8% (11.8-17.7) and 7.4% (5.2-9.6), respectively. Fewer than half of patients received blood tests, and a third received imaging during their ED attendance. The presentation of abdominal pain conveys a significant health burden on families with time off school and ongoing symptoms of pain.

BACKGROUND: Children rarely experience critical illness, resulting in low exposure of emergency physicians (EPs) to critical procedures. Our primary objective was to describe senior EP confidence, most recent performance, and/or supervision of critical nonairway procedures. Secondary objectives were to compare responses between those who work exclusively in PEM and those who do not and to determine whether confidence changed for selected procedures according to increasing patient age. METHODS: Survey of senior EPs working in 96 emergency departments (EDs) affiliated with the Pediatric Emergency Research Networks. Questions assessed training, performance, supervision, and confidence in 11 nonairway critical procedures, including cardiopulmonary resuscitation (CPR), vascular access, chest decompression, and cardiac procedures. RESULTS: Of 2446 physicians, 1503 (61%) responded to the survey. Within the previous year, only CPR and insertion of an intraosseous needle had been performed by at least 50% of respondents: over 20% had performed defibrillation/direct current cardioversion. More than 50% of respondents had never performed or supervised ED thoracotomy, pericardiocentesis, venous cutdown, or transcutaneous pacing. Self-reported confidence was high for all patient age groups for CPR, needle thoracocentesis, tube thoracostomy, intraosseous needle insertion, and defibrillation/DC cardioversion. Confidence levels increased with increasing patient age for central venous and arterial line insertion. Respondents working exclusively in PEM were more likely to report being at least somewhat confident in defibrillation/DC cardioversion, intraosseous needle insertion, and central venous line insertion in particular age groups; however, they were less likely to be at least somewhat confident in ED thoracotomy and transcutaneous pacing. CONCLUSIONS: Cardiopulmonary resuscitation and intraosseous needle insertion were the only critical nonairway procedures performed by at least half of EPs within the previous year. Confidence was higher for these procedures, and needle and tube thoracostomy. These data may inform the development of continuing medical education activities to maintain pediatric procedural skills for emergency physicians.

BACKGROUND: The Pediatric Emergency Care Applied Research Network (PECARN) decision rule demonstrates high sensitivity for identifying children at low risk for clinically important traumatic brain injury (ciTBI). As with the PECARN rule, the Israeli Decision Algorithm for Identifying TBI in Children (IDITBIC) recommends proceeding directly to computed tomography (CT) in children with Glasgow Coma Score (GCS) <15. The aim was to assess the diagnostic accuracy of two clinical rules that assign children with GCS <15 at presentation directly to CT. MATERIALS AND METHODS: Accuracy analysis for detecting ciTBI was performed on a multicenter cohort of children used in the Australasian Pediatric Head Injury Rules Study. RESULTS: The external cohort included 18,913 children; 1691 (8.9%) had CT scan, 160 had ciTBI, and 24 (0.13%) had neurosurgery. Applying IDITBIC and PECARN rules would have missed 11 and 1 ciTBI patients; respectively. All patients with missed injuries were classified as such based on a hospital stay of >2 d. None of these patients died, needed neurosurgery, or required ventilatory support. In children aged <2 y, sensitivity, specificity, positive predictive value and negative predictive value of IDITBIC and PECARN rule were 95.2%, 79.5%, 3.8%, and 99.9% and 100.0%, 59.1%, 2.0%, and 100.0%, respectively. In children ≥2 y, sensitivity, specificity, positive predictive value and negative predictive value of IDITBIC and PECARN rule were 92.4%, 75.3%, 3.1%, and 99.9% and 99.2%, 52.9%, 1.7%, and 100.0%, respectively. CONCLUSIONS: The two decision rules demonstrated high accuracy in identifying ciTBI. As a screening tool, the PECARN rule outperformed IDITBIC. The findings suggest that clinicians should strongly consider directing children with GCS <15 at presentation to CT scan.

AIM: The number of children and young people presenting to emergency departments (EDs) with anxiety and depression is increasing. We aimed to determine parent perspectives on: (i) barriers to accessing non-ED mental health services; and (ii) improving access in the paediatric mental health service system. METHODS: Qualitative study with parents of children and young people aged 0-19 years who attended one of four EDs across Victoria between October 2017 and September 2018 and received a primary diagnosis of anxiety or depression. EXCLUSION CRITERIA: child or young person without a parent/guardian, or presented with self-harm or suicide attempt. Eligible participants completed semi-structured phone interviews. Interviews were recorded and transcripts were coded and analysed using content analysis. RESULTS: A total of 72 parents completed interviews. The average child age was 14 years (standard deviation 2.5) and two thirds identified as female (64%). A total of 57% of children and young people presented with a primary diagnosis of anxiety. Parents reported barriers in accessing care including: service shortages and inaccessibility, underresourced schools, lack of clinician mental health expertise, lack of child-clinician rapport, inconsistent care, financial constraints, lack of mental health awareness among parents, and stigma. Parents want expanded and improved access to services, more respite and support services, supportive schools, and improved mental health education for parents. CONCLUSIONS: Parents of children and young people attending the ED for anxiety and depression are generally dissatisfied with services for child mental health. Solutions that enable parents to better care for their child in the community are needed to improve care.

AIM: To characterise the causes, clinical characteristics and short-term outcomes of neonates who presented to paediatric emergency departments with a head injury. METHODS: Secondary analysis of a prospective data set of paediatric head injuries at 10 emergency departments in Australia and New Zealand. Patients without neuroimaging were followed up by telephone call. We extracted epidemiological information, clinical findings and outcomes in neonates (≤28 days). RESULTS: Of 20 137 children with head injuries, 93 (0.5%) occurred in neonates. These were mostly fall-related (75.2%), commonly from a care giver's arms, or due to being accidentally struck by a person/object (20.4%). There were three cases of non-accidental head injuries (3.2%). Most neonates were asymptomatic (67.7%) and many had no findings on examination (47.3%). Most neonates had a Glasgow Coma Scale 15 (89.2%) or 14 (7.5%). A total of 15.1% presented with vomiting and 5.4% were abnormally drowsy. None had experienced a loss of consciousness. The most common findings on examination were scalp haematoma (28.0%) and possible palpable skull fracture (6.5%); 8.6% underwent computed tomography brain scan and 4.3% received an ultrasound. Five of eight computed tomography scan (5.4% of neonates overall) showed traumatic brain injury and two of four (2.2% overall) had traumatic brain injury on ultrasound. Thirty-seven percent were admitted, one patient was intubated and none had neurosurgery or died. CONCLUSIONS: Neonatal head injuries are rare with a mostly benign short-term outcome and are appropriate for observation. However, non-accidental injuries need to be considered.

AIM: Abusive head trauma (AHT) is associated with high morbidity and mortality. We aimed to describe characteristics of cases where clinicians suspected AHT and confirmed AHT cases and describe how they differed. METHODS: This was a planned secondary analysis of a prospective multicentre cohort study of head injured children aged <18 years across five centres in Australia and New Zealand. We identified cases of suspected AHT when emergency department clinicians raised suspicion on a clinical report form or based on research assistant-assigned epidemiology codes. Cases were categorised as AHT positive, negative and indeterminate after multidisciplinary review. Suspected and confirmed AHT and non-AHT cases were compared using odds ratios with 95% confidence intervals. RESULTS: AHT was suspected in 70 of 13 371 (0.5%) head-injured children. Of these, 23 (32.9%) were categorised AHT positive, 18 (25.7%) AHT indeterminate and 29 (27.1%) AHT negative. Median age was 0.8 years in suspected, 1.4 years in confirmed AHT and 4.1 years in non-AHT cases. Odds ratios (95% confidence interval) for presenting features and outcomes in confirmed AHT versus non-AHT were: loss of consciousness 2.8 (1.2-6.9), scalp haematoma 3.9 (1.7-9.0), seizures 12.0 (4.0-35.5), Glasgow coma scale ≤12 30.3 (11.8-78.0), abnormal neuroimaging 38.3 (16.8-87.5), intensive care admission 53.4 (21.6-132.5) and mortality 105.5 (22.2-500.4). CONCLUSIONS: Emergency department presentations of children with suspected and confirmed AHT had higher rates of loss of consciousness, scalp haematomas, seizures and low Glasgow coma scale. These cases were at increased risk of abnormal computed tomography scans, need for intensive care and death.

AIM: To assess computerised tomography (CT) use and the risk of intracranial haemorrhage (ICH) in children with bleeding disorders following a head trauma. METHODS: Design: Multicentre prospective observational study. SETTING: 10 paediatric emergency departments (ED) in Australia and New Zealand. PATIENTS: Children <18 years with and without bleeding disorders assessed in ED following head trauma between April 2011 and November 2014. INTERVENTIONS: Data collection of patient characteristics, management and outcomes. MAIN OUTCOME MEASURES: Rate of CT use and frequency of ICH on CT. RESULTS: Of 20 137 patients overall, 103 (0.5%) had a congenital or acquired bleeding disorder. CT use was higher in these patients compared with children without bleeding disorders (30.1 vs. 10.4%; rate ratio 2.91 95% CI 2.16-3.91). Only one of 31 (3.2%) children who underwent CT in the ED had an ICH. This patient rapidly deteriorated in the ED on arrival and required neurosurgery. None of the patients with bleeding disorders who did not have a CT obtained in the ED or had an initial negative CT had evidence of ICH on follow up. CONCLUSIONS: Although children with a bleeding disorder and a head trauma more often received a CT scan in the ED, their risk of ICH seemed low and appeared associated with post-traumatic clinical findings. Selective CT use combined with observation may be cautiously considered in these children based on clinical presentation and severity of bleeding disorder.

STUDY OBJECTIVE: Existing clinical decision rules guide management for head-injured children presenting 24 hours or sooner after injury, even though some may present greater than 24 hours afterward. We seek to determine the prevalence of traumatic brain injuries for patients presenting to emergency departments greater than 24 hours after injury and identify symptoms and signs to guide management. METHODS: This was a planned secondary analysis of the Australasian Paediatric Head Injury Rule Study, concentrating on first presentations greater than 24 hours after injury, with Glasgow Coma Scale scores 14 and 15. We sought associations with predictors of traumatic brain injury on computed tomography (CT) and clinically important traumatic brain injury. RESULTS: Of 19,765 eligible children, 981 (5.0%) presented greater than 24 hours after injury, and 465 injuries (48.5%) resulted from falls less than 1 m and 37 (3.8%) involved traffic incidents. Features associated significantly with presenting greater than 24 hours after injury in comparison with presenting within 24 hours were nonfrontal scalp hematoma (20.8% versus 18.1%), headache (31.6% versus 19.9%), vomiting (30.0% versus 16.3%), and assault with nonaccidental injury concerns (1.4% versus 0.4%). Traumatic brain injury on CT occurred in 37 patients (3.8%), including suspicion of depressed skull fracture (8 [0.8%]) and intracranial hemorrhage (31 [3.8%]). Clinically important traumatic brain injury occurred in 8 patients (0.8%), with 2 (0.2%) requiring neurosurgery, with no deaths. Suspicion of depressed skull fracture was associated with traumatic brain injury on CT consistently, with the only other significant factor being nonfrontal scalp hematoma (odds ratio 19.0; 95% confidence interval 8.2 to 43.9). Clinically important traumatic brain injury was also associated with nonfrontal scalp hematoma (odds ratio 11.7; 95% confidence interval 2.4 to 58.6) and suspicion of depressed fracture (odds ratio 19.7; 95% confidence interval 2.1 to 182.1). CONCLUSION: Delayed presentation after head injury, although infrequent, is significantly associated with traumatic brain injury. Evaluation of delayed presentations must consider identified factors associated with this increased risk.

STUDY OBJECTIVE: To determine the cost-effectiveness of 3 clinical decision rules in comparison to Australian and New Zealand usual care: the Children's Head Injury Algorithm for the Prediction of Important Clinical Events (CHALICE), the Pediatric Emergency Care Applied Research Network (PECARN), and the Canadian Assessment of Tomography for Childhood Head Injury (CATCH). METHODS: A decision analytic model was constructed from the Australian health care system perspective to compare costs and outcomes of the 3 clinical decision rules compared with Australian and New Zealand usual care. The study involved multicenter recruitment from 10 Australian and New Zealand hospitals; recruitment was based on the Australian Pediatric Head Injury Rules Study involving 18,913 children younger than 18 years and with a head injury, and with Glasgow Coma Scale score 13 to 15 on presentation to emergency departments (EDs). We determined the cost-effectiveness of the 3 clinical decision rules compared with usual care. RESULTS: Usual care, CHALICE, PECARN, and CATCH strategies cost on average AUD $6,390, $6,423, $6,433, and $6,457 per patient, respectively. Usual care was more effective and less costly than all other strategies and is therefore the dominant strategy. Probabilistic sensitivity analyses showed that when simulated 1,000 times, usual care dominated all clinical decision rules in 61%, 62%, and 60% of simulations (CHALICE, PECARN, and CATCH, respectively). The difference in cost between all rules was less than $36 (95% confidence interval -$7 to $77) and the difference in quality-adjusted life-years was less than 0.00097 (95% confidence interval 0.0015 to 0.00044). Results remained robust under sensitivity analyses. CONCLUSION: This evaluation demonstrated that the 3 published international pediatric head injury clinical decision rules were not more cost-effective than usual care in Australian and New Zealand tertiary EDs. Understanding the usual care context and the likely cost-effectiveness is useful before investing in implementation of clinical decision rules or incorporation into a guideline.

BACKGROUND: Clinical decision rules can help to determine the need for CT imaging in children with head injuries. We aimed to validate three clinical decision rules (PECARN, CATCH, and CHALICE) in a large sample of children. METHODS: In this prospective observational study, we included children and adolescents (aged <18 years) with head injuries of any severity who presented to the emergency departments of ten Australian and New Zealand hospitals. We assessed the diagnostic accuracy of PECARN (stratified into children aged <2 years and ≥2 years), CATCH, and CHALICE in predicting each rule-specific outcome measure (clinically important traumatic brain injury [TBI], need for neurological intervention, and clinically significant intracranial injury, respectively). For each calculation we used rule-specific predictor variables in populations that satisfied inclusion and exclusion criteria for each rule (validation cohort). In a secondary analysis, we compiled a comparison cohort of patients with mild head injuries (Glasgow Coma Scale score 13-15) and calculated accuracy using rule-specific predictor variables for the standardised outcome of clinically important TBI. This study is registered with the Australian New Zealand Clinical Trials Registry, number ACTRN12614000463673. FINDINGS: Between April 11, 2011, and Nov 30, 2014, we analysed 20â137 children and adolescents attending with head injuries. CTs were obtained for 2106 (10%) patients, 4544 (23%) were admitted, 83 (<1%) underwent neurosurgery, and 15 (<1%) died. PECARN was applicable for 4011 (75%) of 5374 patients younger than 2 years and 11â152 (76%) of 14â763 patients aged 2 years and older. CATCH was applicable for 4957 (25%) patients and CHALICE for 20â029 (99%). The highest point validation sensitivities were shown for PECARN in children younger than 2 years (100·0%, 95% CI 90·7-100·0; 38 patients identified of 38 with outcome [38/38]) and PECARN in children 2 years and older (99·0%, 94·4-100·0; 97/98), followed by CATCH (high-risk predictors only; 95·2%; 76·2-99·9; 20/21; medium-risk and high-risk predictors 88·7%; 82·2-93·4; 125/141) and CHALICE (92·3%, 89·2-94·7; 370/401). In the comparison cohort of 18â913 patients with mild injuries, sensitivities for clinically important TBI were similar. Negative predictive values in both analyses were higher than 99% for all rules. INTERPRETATION: The sensitivities of three clinical decision rules for head injuries in children were high when used as designed. The findings are an important starting point for clinicians considering the introduction of one of the rules.

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.

STUDY OBJECTIVE: Three clinical decision rules for head injuries in children (Pediatric Emergency Care Applied Research Network [PECARN], Canadian Assessment of Tomography for Childhood Head Injury [CATCH], and Children's Head Injury Algorithm for the Prediction of Important Clinical Events [CHALICE]) have been shown to have high performance accuracy. The utility of any of these in a particular setting depends on preexisting clinician accuracy. We therefore assess the accuracy of clinician practice in detecting clinically important traumatic brain injury. METHODS: This was a planned secondary analysis of a prospective observational study of children younger than 18 years with head injuries at 10 Australian and New Zealand centers. In a cohort of children with mild head injuries (Glasgow Coma Scale score 13 to 15, presenting in <24 hours) we assessed physician accuracy (computed tomography [CT] obtained in emergency departments [EDs]) for the standardized outcome of clinically important traumatic brain injury and compared this with the accuracy of PECARN, CATCH, and CHALICE. RESULTS: Of 20,137 children, 18,913 had a mild head injury. Of these patients, 1,579 (8.3%) received a CT scan during the ED visit, 160 (0.8%) had clinically important traumatic brain injury, and 24 (0.1%) underwent neurosurgery. Clinician identification of clinically important traumatic brain injury based on CT performed had a sensitivity of 158 of 160, or 98.8% (95% confidence interval [CI] 95.6% to 99.8%) and a specificity of 17,332 of 18,753, or 92.4% (95% CI 92.0% to 92.8%). Sensitivity of PECARN for children younger than 2 years was 42 of 42 (100.0%; 95% CI 91.6% to 100.0%), and for those 2 years and older, it was 117 of 118 (99.2%; 95% CI 95.4% to 100.0%); for CATCH (high/medium risk), it was 147 of 160 (91.9%; 95% CI 86.5% to 95.6%); and for CHALICE, 148 of 160 (92.5%; 95% CI 87.3% to 96.1%). CONCLUSION: In a setting with high clinician accuracy and a low CT rate, PECARN, CATCH, or CHALICE clinical decision rules have limited potential to increase the accuracy of detecting clinically important traumatic brain injury and may increase the CT rate.

OBJECTIVE: To prospectively compare the proportion of traumatic brain injuries (TBIs) that would be classified as mild by applying different published definitions of mild TBI to a large prospectively collected dataset, and to examine the variability in the proportions included by various definitions. DESIGN: Prospective observational study. SETTING: Hospital emergency departments. PARTICIPANTS: Children (N=11,907) aged 3 to 16 years (mean age, 8.2±3.9y). Of the participants, 3868 (32.5%) were girls, and 7374 (61.9%) of the TBIs were the result of a fall. Median Glasgow Coma Scale score was 15. MAIN OUTCOME MEASURES: We applied 17 different definitions of mild TBI, identified through a published systematic review, to children aged 3 to 16 years. Adjustments and clarifications were made to some definitions. The number and percentage identified for each definition is presented. RESULTS: Adjustments had to be made to the 17 definitions to apply to the dataset: none in 7, minor to substantial in 10. The percentage classified as mild TBI across definitions varied from 7.1% (n=841) to 98.7% (n=11,756) and varied by age group. CONCLUSIONS: When applying the 17 definitions of mild TBI to a large prospective multicenter dataset of TBI, there was wide variability in the number of cases classified. Clinicians and researchers need to be aware of this variability when examining literature concerning children with mild TBI.

AIM: Penetrating head injuries (pHIs) are associated with high morbidity and mortality. Data on pHIs in children outside North America are limited. We describe the mechanism of injuries, neuroimaging findings, neurosurgery and mortality for pHIs in Australia and New Zealand. METHODS: This was a planned secondary analysis of a prospective observational study of children <18 years who presented with a head injury of any severity at any of 10 predominantly paediatric Australian/New Zealand emergency departments (EDs) between 2011 and 2014. We reviewed all cases where clinicians had clinically suspected pHI as well as all cases of clinically important traumatic brain injuries (death, neurosurgery, intubation >24 h, admission >2 days and abnormal computed tomography). RESULTS: Of 20 137 evaluable patients with a head injury, 21 (0.1%) were identified to have sustained a pHI. All injuries were of non-intentional nature, and there were no gunshot wounds. The mechanisms of injuries varied from falls, animal attack, motor vehicle crashes and impact with objects. Mean Glasgow Coma Scale on ED arrival was 10; 10 (48%) had a history of loss of consciousness, and 7 (33%) children were intubated pre-hospital or in the ED. Fourteen (67%) children underwent neurosurgery, two (10%) craniofacial surgery, and five (24%) were treated conservatively; four (19%) patients died. CONCLUSIONS: Paediatric pHIs are very rare in EDs in Australia and New Zealand but are associated with high morbidity and mortality. The absence of firearm-related injuries compared to North America is striking and may reflect Australian and New Zealand firearm regulations.

BACKGROUND: Bell's palsy or acute idiopathic lower motor neurone facial paralysis is characterized by sudden onset paralysis or weakness of the muscles to one side of the face controlled by the facial nerve. While there is high level evidence in adults demonstrating an improvement in the rate of complete recovery of facial nerve function when treated with steroids compared with placebo, similar high level studies on the use of steroids in Bell's palsy in children are not available. The aim of this study is to assess the utility of steroids in Bell's palsy in children in a randomised placebo-controlled trial. METHODS/DESIGN: We are conducting a randomised, triple-blinded, placebo controlled trial of the use of prednisolone to improve recovery from Bell's palsy at 1 month. Study sites are 10 hospitals within the Australian and New Zealand PREDICT (Paediatric Research in Emergency Departments International Collaborative) research network. 540 participants will be enrolled. To be eligible patients need to be aged 6 months to < 18 years and present within 72 hours of onset of clinician diagnosed Bell's palsy to one of the participating hospital emergency departments. Patients will be excluded in case of current use of or contraindications to steroids or if there is an alternative diagnosis. Participants will receive either prednisolone 1 mg/kg/day to a maximum of 50 mg/day or taste matched placebo for 10 days. The primary outcome is complete recovery by House-Brackmann scale at 1 month. Secondary outcomes include assessment of recovery using the Sunnybrook scale, the emotional and functional wellbeing of the participants using the Pediatric Quality of Life Inventory and Child Health Utility 9D Scale, pain using Faces Pain Scale Revised or visual analogue scales, synkinesis using a synkinesis assessment questionnaire and health utilisation costs at 1, 3 and 6 months. Participants will be tracked to 12 months if not recovered earlier. Data analysis will be by intention to treat with primary outcome presented as differences in proportions and an odds ratio adjusted for site and age. DISCUSSION: This large multicenter randomised trial will allow the definitive assessment of the efficacy of prednisolone compared with placebo in the treatment of Bell's palsy in children. TRIAL REGISTRATION: The study is registered with the Australian New Zealand Clinical Trials Registry ACTRN12615000563561 (1 June 2015).

AIM: To compare the parental motivators and referring general practitioner's (GP's) reasons for advising emergency department (ED) attendance with the assessment of ED medical staff. To compare ED clinician opinion with other published methods that have attempted to define 'primary care suitable' presentations to the ED. METHODS: A prospective observational study and series of surveys regarding the attendance of children presenting to a single tertiary paediatric ED. Surveys were distributed to the treating ED clinician, the child's parent/guardian, and the referring GP. Results between the three groups were analysed and compared. RESULTS: There were a total of 1069 presentations during the study period. Six hundred (58.4%, 95% CI 55.3-61.4%) presentations were judged as 'ED appropriate' by the treating ED clinician. When compared with methods used to retrospectively judge whether ED patients are considered 'primary care suitable', ED clinicians disagree between 22.4 and 38.8% of the time. For patients who presented directly to ED, 85.6% did so for a medical reason, whilst 32.1% did so for a GP access reason. Being referred by a GP improved the ED clinicians' opinion of the appropriateness of the presentation (49.2 vs. 73.9%, P < 0.05). CONCLUSIONS: We caution that many strategies attempting to 'solve' the issue of increasing ED attendances by paediatric patients have been driven by opinion, and a better understanding of the motivators that drive this behaviour is needed. We believe the solution to increasing utilisation of EDs by children must be a balanced approach that addresses community expectations and appropriately resources EDs.

AIM: The aetiology and clinical course of Bell's palsy may be different in paediatric and adult patients. There is no randomised placebo controlled trial (RCT) to show effectiveness of prednisolone for Bell's palsy in children. The aim of the study was to assess current practice in paediatric Bell's palsy in Australia and New Zealand Emergency Departments (ED) and determine the feasibility of conducting a multicentre RCT within the Paediatric Research in Emergency Departments International Collaborative (PREDICT). METHODS: A retrospective analysis of ED medical records of children less than 18 years diagnosed with Bell's palsy between 1 January, 2012 and 31 December, 2013 was performed. Potential participants were identified from ED information systems using Bell's palsy related search terms. Repeat presentations during the same illness were excluded but relapses were not. Data on presentation, diagnosis and management were entered into an online data base (REDCap). RESULTS: Three hundred and twenty-three presentations were included from 14 PREDICT sites. Mean age at presentation was 9.0 (SD 5.0) years with 184 (57.0%) females. Most (238, 73.7%) presented to ED within 72 h of symptoms, 168 (52.0%) had seen a doctor prior. In ED, 218 (67.5%) were treated with steroids. Prednisolone was usually prescribed for 9 days at around 1 mg/kg/day, with tapering in 35.7%. CONCLUSION: Treatment of Bell's palsy in children presenting to Australasian EDs is varied. Prednisolone is commonly used in Australasian EDs, despite lack of high-level paediatric evidence. The study findings confirm the feasibility of an RCT of prednisolone for Bell's palsy in children.
