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. [ABSTRACT FROM AUTHOR]

The article focuses on seizures and syncope in children can lead to head injuries (HIs), fractures, soft tissue injuries and burns. Topics include the incidence and severity of HI associated with seizures and syncope are unclear because of variable settings, the syncope occurs in up to one third of children and adolescents with a broad aetiology, and the frequency and outcomes of seizure- and syncope-related HI in a large paediatric cohort.

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. [ABSTRACT FROM AUTHOR]

BACKGROUND AND OBJECTIVES: International patterns of antibiotic use and laboratory testing in bronchiolitis in emergency departments are unknown. Our objective is to evaluate variation in the use of antibiotics and nonindicated tests in infants with bronchiolitis in 38 emergency departments in Pediatric Emergency Research Networks in Canada, the United States, Australia and New Zealand, the United Kingdom and Ireland, and Spain and Portugal. We hypothesized there would be significant variation, adjusted for patient characteristics. METHODS: We analyzed a retrospective cohort study of previously healthy infants aged 2 to 12 months with bronchiolitis. Variables examined included network, poor feeding, dehydration, nasal flaring, chest retractions, apnea, saturation, respiratory rate, fever, and suspected bacterial infection. Outcomes included systemic antibiotic administration and urine, blood, or viral testing or chest radiography (CXR). RESULTS: In total, 180 of 2359 (7.6%) infants received antibiotics, ranging from 3.5% in the United Kingdom and Ireland to 11.1% in the United States. CXR (adjusted odds ratio [aOR] 2.3; 95% confidence interval 1.6-3.2), apnea (aOR 2.2; 1.1-3.5), and fever (aOR 2.4; 1.7-3.4) were associated with antibiotic use, which did not vary across networks (P = .15). In total, 768 of 2359 infants (32.6%) had ≥1 nonindicated test, ranging from 12.7% in the United Kingdom and Ireland to 50% in Spain and Portugal. Compared to the United Kingdom and Ireland, the aOR (confidence interval) results for testing were Canada 5.75 (2.24-14.76), United States 4.14 (1.70-10.10), Australia and New Zealand 2.25 (0.86-5.74), and Spain and Portugal 3.96 (0.96-16.36). Testing varied across networks (P < .0001) and was associated with suspected bacterial infections (aOR 2.12; 1.30-2.39) and most respiratory distress parameters. Viral testing (591 of 768 [77%]) and CXR (507 of 768 [66%]) were obtained most frequently. CONCLUSIONS: The rate of antibiotic use in bronchiolitis was low across networks and was associated with CXR, fever, and apnea. Nonindicated testing was common outside of the United Kingdom and Ireland and varied across networks irrespective of patient characteristics. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Objectives: Variation in the management of paediatric head injury has been identified worldwide. This prospective study describes imaging and admission practices of children presenting with head injury across 10 hospital EDs in Australia and New Zealand. Methods: Prospective observational multicentre study of 20 137 children (under 18 years) as a planned secondary analysis of the Australasian Paediatric Head Injury Rules Study. All presentations with head injury without prior imaging were eligible for inclusion. Variations in rates of computed tomography of the brain (CTB) and admission practices between sites, ED type and country were investigated, as were clinically important traumatic brain injuries (ciTBIs) and abnormal CTBs within CTBs. Results: Among the 20 137 enrolled patients, the site adjusted CTB rate was 11.2% (95% confidence interval [CI] 7.8–14.6); individual sites ranged from 2.6 to 18.6%. ciTBI was found in 0.4–2.2%, with abnormal scans documented in 0.7–6.5%. As a percentage of CTBs undertaken, ciTBIs were found in 12.8% (95% CI 10.8–14.7) with individual site variation of 8.8–16.9%, and no statistically significant difference noted, and traumatic abnormalities in 29.3% (95% CI 26.2–32.3) with individual site variation between 19.4 and 35.6%. Among those under 2 years,traumatic abnormalities were found in greater than 50% of CTBs at 90% of sites. Admission rate overall was 24.0% (site adjusted) with wide variation between sites (5.0–48.9%). Conclusion: Across the 10 largely tertiary EDs included in this study, the overall CTB rate was low with no significant variation between sites when adjusted for ciTBIs. [ABSTRACT FROM AUTHOR]

Objective: Although there is a large body of research on head injury (HI) inflicted by caregivers in young children, little is known about intentional HI in older children and inflicted HI by perpetrators other than carers. Therefore, we set out to describe epidemiology, demographics and severity of intentional HIs in childhood. Methods: A planned secondary analysis of a prospective multicentre cohort study was conducted in 10 EDs in Australia and New Zealand, including children aged <18 years with HIs. Epidemiology codes were used to prospectively code the injuries. Demographic and clinical information including the rate of clinically important traumatic brain injury (ciTBI: HI leading to death, neurosurgery, intubation >1 day or admission ≥2 days with abnormal computed tomography [CT]) was descriptively analysed. Results: Intentional injuries were identified in 372 of 20 137 (1.8%) head‐injured children. Injuries were caused by caregivers (103, 27.7%), by peers (97, 26.1%), by siblings (47, 12.6%), by strangers (35, 9.4%), by persons with unknown relation to the patient (21, 5.6%), other intentional injuries (8, 2.2%) or undetermined intent (61, 16.4%). About 75.7% of victims of assault by caregivers were <2 years, whereas in other categories, only 4.9% were <2 years. Overall, 66.9% of victims were male. Rates of CT performance and abnormal CT varied: assault by caregivers 68.9%/47.6%, by peers 18.6%/27.8%, by strangers 37.1%/5.7%. ciTBI rate was 22.3% in assault by caregivers, 3.1% when caused by peers and 0.0% with other perpetrators. Conclusions: Intentional HI is infrequent in children. The most frequently identified perpetrators are caregivers and peers. Caregiver injuries are particularly severe. [ABSTRACT FROM AUTHOR]

BACKGROUND AND OBJECTIVES: A 4-variable abusive head trauma (AHT) clinical prediction rule (CPR) for use in the PICU was derived and validated for children <3 years of age by the Pediatric Brain Injury Research Network (PediBIRN). We aimed to externally validate PediBIRN as designed (PICU only) as well as using broader inclusion criteria (admitted children with head injuries). METHODS: This was a secondary analysis of a prospective multicenter study of pediatric head injuries at 5 Australian and New Zealand tertiary pediatric centers. Possible AHT was identified by clinician suspicion, epidemiology codes, or a high-risk group (<3 years of age, admitted, abnormal neuroimaging results). At 1 center, we additionally reviewed head injuries in the forensic database. We designated patients as positive for AHT, negative for AHT, or having indeterminate outcome after multidisciplinary review and applied the PediBIRN CPR, blinded to outcome, to PICU admissions only, and any head injury admissions. CPR accuracy was calculated by using 95% confidence intervals. RESULTS: One hundred and forty-one patients were admitted with abnormal neuroimaging results. Twenty-eight (20%) were positive for AHT, 94 (67%) were negative for AHT, and 19 (13%) had indeterminate outcome. Excluding indeterminate cases, in the PICU (n = 28), the CPR was 100% (75%-100%) sensitive and 11% (0%-48%) specific; in all admitted patients (n = 141), sensitivity was 96% (82% -100%) and specificity of 43% (32%-53%). CONCLUSIONS: This validation revealed high sensitivity and low specificity for PICU patients. Specificity was improved but moderate in a broader group of admitted head injury patients.

OBJECTIVES: To determine the prevalence of traumatic brain injuries in children who vomit after head injury and identify variables from published clinical decision rules (CDRs) that predict increased risk. METHODS: Secondary analysis of the Australasian Paediatric Head Injury Rule Study. Vomiting characteristics were assessed and correlated with CDR predictors and the presence of clinically important traumatic brain injury (ciTBI) or traumatic brain injury on computed tomography (TBI-CT). Isolated vomiting was defined as vomiting without other CDR predictors. RESULTS: Of the 19 920 children enrolled, 3389 (17.0%) had any vomiting, with 2446 (72.2%) >2 years of age. In 172 patients with ciTBI, 76 had vomiting (44.2%; 95% confidence interval [CI] 36.9%-51.7%), and in 285 with TBI-CT, 123 had vomiting (43.2%; 95% CI 37.5%-49.0%o). With isolated vomiting, only 1 (0.3%; 95% CI 0.0%-0.9%) had ciTBI and 2 (0.6%; 95% CI 0.0%-1.4%o) had TBI-CT. Predictors of increased risk of ciTBI with vomiting by using multivariate regression were as follows: signs of skull fracture (odds ratio [OR] 80.1; 95% CI 43.4-148.0), altered mental status (OR 2.4; 95% CI 1.0-5.5), headache (OR 2.3; 95% CI 1.3-4.1), and acting abnormally (OR 1.86; 95% CI 1.0-3.4). Additional features predicting TBI-CT were as follows: skull fracture (OR 112.96; 95% CI 66.76-191.14), nonaccidental injury concern (OR 6.75; 95% CI 1.54-29.69), headache (OR 2.55; 95% CI 1.52-4.27), and acting abnormally (OR 1.83; 95% CI 1.10-3.06). CONCLUSIONS: TBI-CT and ciTBI are uncommon in children presenting with head injury with isolated vomiting, and a management strategy of observation without immediate computed tomography appears appropriate.

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 20 137 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 11 152 (76%) of 14 763 patients aged 2 years and older. CATCH was applicable for 4957 (25%) patients and CHALICE for 20 029 (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 18 913 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.Funding: National Health and Medical Research Council, Emergency Medicine Foundation, Perpetual Philanthropic Services, WA Health Targeted Research Funds, Townsville Hospital Private Practice Fund, Auckland Medical Research Foundation, A + Trust.

Aim: To examine Australian and New Zealand emergency department (ED) staff's training, knowledge and confidence regarding trauma-informed care for children after trauma, and barriers to implementation.Methods: ED staff's perspectives on trauma-informed care were assessed using a web-based self-report questionnaire. Participants included 468 ED staff (375 nursing and 111 medical staff) from hospitals in Australia and New Zealand. Data analyses included descriptive statistics, χ2 tests and multiple regressions.Results: Over 90% of respondents had not received training in trauma-informed care and almost all respondents (94%) wanted training in this area. While knowledge was associated with a respondent's previous training and profession, confidence was associated with the respondent's previous training, experience level and workplace. Dominant barriers to the implementation of trauma-informed care were lack of time and lack of training.Conclusions: There is a need and desire for training and education of Australian and New Zealand ED staff in trauma-informed care. This study demonstrates that experience alone is not sufficient for the development of knowledge of paediatric traumatic stress reactions and trauma-informed care practices. Existing education materials could be adapted for use in the ED and to accommodate the training preferences of Australian and New Zealand ED staff. [ABSTRACT FROM AUTHOR]
