Objective: Incidence and short‐term outcomes of clinically important traumatic brain injury (ciTBI) in head‐injured children presenting to ED with post‐traumatic seizure (PTS) is not described in current literature. Methods: Planned secondary analysis of a prospective observational study undertaken in 10 Australasian Paediatric Research in Emergency Departments International Collaborative (PREDICT) network EDs between 2011 and 2014 of head‐injured children <18 years with and without PTS. Clinical predictors and outcomes were analysed by attributable risk (AR), risk ratios (RR) and 95% confidence interval (CI), including the association with Glasgow Coma Scale (GCS) scores. Results: Of 20 137 head injuries, 336 (1.7%) had PTS with median age of 4.8 years. Initial GCS was 15 in 268/336 (79.8%, AR −16.1 [95% CI −20.4 to −11.8]), 14 in 24/336 (7.1%, AR 4.4 [95% CI 1.6–7.2]) and ≤13 in 44/336 (13.1%, AR 11.7 [95% CI 8.1–15.3]) in comparison with those without PTS, respectively. The ciTBI rate was 34 (10.1%) with PTS versus 219 (1.1%) without PTS (AR 9.0 [95% CI 5.8–12.2]) with 5/268 (1.9%), 6/24 (25.0%) and 23/44 (52.3%) with GCS 15, 14 and ≤13, respectively. In PTS, rates of admission ≥2 nights (34 [10.1%] AR 9.0 [95% CI 5.8–12.3]), intubation >24 h (9 [2.7%] AR 2.5 [95% CI 0.8–4.2]) and neurosurgery (8 [2.4%] AR 2.0 [95% CI 0.4–3.7]), were higher than those without PTS. Children with PTS and GCS 15 or 14 had no neurosurgery, intubations or death, with two deaths in children with PTS and GCS ≤13. Conclusions: PTS was uncommon in head‐injured children presenting to the ED but associated with an increased risk of ciTBI in those with reduced GCS on arrival. [ABSTRACT FROM AUTHOR]

Viral bronchiolitis is the most common cause of admission to hospital for infants in high-income countries. Respiratory syncytial virus accounts for 60-80% of bronchiolitis presentations. Bronchiolitis is diagnosed clinically without the need for viral testing. Management recommendations, based predominantly on high-quality evidence, advise clinicians to support hydration and oxygenation only. Evidence suggests no benefit with use of glucocorticoids or bronchodilators, with further evidence required to support use of hypertonic saline in bronchiolitis. Evidence is scarce in the intensive care unit. Evidence suggests use of high-flow therapy in bronchiolitis is limited to rescue therapy after failure of standard subnasal oxygen only in infants who are hypoxic and does not decrease rates of intensive care unit admission or intubation. Despite systematic reviews and international clinical practice guidelines promoting supportive rather than interventional therapy, universal de-implementation of interventional care in bronchiolitis has not occurred and remains a major challenge.

Objectives: The Pediatric Emergency Research Network (PERN) was launched in 2009 with the intent for existing national and regional research networks in paediatric emergency care to organise globally for the conduct of collaborative research across networks. Methods: PERN has grown from five to eight member networks over the past decade. With an executive committee comprising representatives from all member networks, PERN plays a supportive and collaborative rather than governing role. The full impact of PERN's facilitation of international collaborative research, although somewhat difficult to quantify empirically, can be measured indirectly by the observed growth of the field, the nature of the increasingly challenging research questions now being addressed and the collective capacity to generate and implement new knowledge in treating acutely ill and injured children. Results: Beginning as a pandemic response studying H1N1 influenza risk factors in children, PERN research has progressed to multiple observational studies and ongoing global randomised controlled trials (RCTs). As a recent example, PERN has developed sufficient network infrastructure to enable the rapid initiation of a prospective observational study in response to the current COVID‐19 pandemic. Conclusions: Following its success with developing global research, the PERN goal now is to promote the implementation of scientific advances into everyday clinical practice by: (i) expanding the capacity for global RCTs; (ii) deepening the focus on implementation science; (iii) increasing attention to healthcare disparities; and (iv) expanding PERN's reach into resource‐restricted regions. Through these actions, PERN aims to meet the needs of acutely ill and injured children throughout the world. [ABSTRACT FROM AUTHOR]

Background: Understanding how and why de-implementation of low-value practices is sustained remains unclear. The Paediatric Research in Emergency Departments International CollaboraTive (PREDICT) Bronchiolitis Knowledge Translation (KT) Study was a cluster randomised controlled trial conducted in 26 Australian and New Zealand hospitals (May-November 2017). Results showed targeted, theory-informed interventions (clinical leads, stakeholder meetings, train-the-trainer workshop, targeted educational package, audit/feedback) were effective at reducing use of five low-value practices for bronchiolitis (salbutamol, glucocorticoids, antibiotics, adrenaline and chest x-ray) by 14.1% in acute care settings. The primary aim of this study is to determine the sustainability (continued receipt of benefits) of these outcomes at intervention hospitals two-years after the removal of study supports. Secondary aims are to determine sustainability at one-year after removal of study support at intervention hospitals; improvements one-and-two years at control hospitals; and explore factors that influence sustainability at intervention hospitals and contribute to improvements at control hospitals.Methods: A mixed-methods study design. The quantitative component is a retrospective medical record audit of bronchiolitis management within 24 hours of emergency department (ED) presentations at 26 Australian (n = 20) and New Zealand (n = 6) hospitals, which participated in the PREDICT Bronchiolitis KT Study. Data for a total of 1800 infants from intervention and control sites (up to 150 per site) will be collected to determine if improvements (i.e., no use of all five low-value practices) were sustained two- years (2019) post-trial (primary outcome; composite score); and a further 1800 infants from intervention and control sites will be collected to determine sustained improvements one- year (2018) post-trial (secondary outcome). An a priori definition of sustainability will be used. The qualitative component will consist of semi-structured interviews with three to five key emergency department and paediatric inpatient medical and nursing staff per site (total n = 78-130). Factors that may have contributed to sustaining outcomes and/or interventions will be explored and mapped to an established sustainability framework.Discussion: This study will improve our understanding of the sustainability of evidence-based bronchiolitis management in infants. Results will also advance implementation science research by informing future de-implementation strategies to reduce low-value practices and sustain practice change in paediatric acute care.Trial Registration: Australian and New Zealand Clinical Trials Registry No: ACTRN12621001287820.

Several of the manuscripts included in this special issue demonstrate how positive transformative actions across policy and practice can influence the health and wellbeing outcomes of children and young people. The links between colonisation and significant health inequities that occur for Indigenous peoples compared with non-Indigenous is well described internationally and in Aotearoa New Zealand. Childhood and young adulthood are important stages of growing, learning and development. As part of this, we have ensured that there is rangatahi Maori representation on the guest editorial team for this special issue, as well as inclusion of rangatahi Maori and other young people as authors of its constituent manuscripts.

Objective: Clinical practice guidelines (CPGs) are an important tool for the management of children with sepsis. The quality, consistency and concordance of Australian and New Zealand (ANZ) childhood sepsis CPGs with the Australian Commission on Safety and Quality in Healthcare (ACSQHC) sepsis clinical care standards and international sepsis guidelines is unclear. Methods: We accessed childhood sepsis CPGs for all ANZ states and territories through Paediatric Research in Emergency Departments International Collaborative members. The guidelines were assessed for quality using the AGREE‐II instrument. Consistency between CPG treatment recommendations was assessed, as was concordance with the ACSQHC sepsis clinical care standards and international sepsis guidelines. Results: Overall, eight CPGs were identified and assessed. CPGs used a narrative and pathway format, with those using both having the highest quality overall. CPG quality was highest for description of scope and clarity of presentation, and lowest for editorial independence. Consistency between guidelines for initial treatment recommendations was poor, with substantial variation in the choice and urgency of empiric antimicrobial administration; the choice, volume and urgency of fluid resuscitation; and the choice of first‐line vasoactive agent. Most CPGs were concordant with time‐critical components of the ACSQHC sepsis clinical care standard, although few addressed post‐acute care. Concordance with international sepsis guidelines was poor. Conclusion: Childhood sepsis CPGs in current use in ANZ are of variable quality and lack consistency with key treatment recommendations. CPGs are concordant with the ACSQHC care standard, but not with international sepsis guidelines. A bi‐national sepsis CPG may reduce unnecessary variation in care. [ABSTRACT FROM AUTHOR]

Objective: Determination of the real‐world performance of a health care system in the treatment of status epilepticus (SE). Methods: Prospective, multicenter population‐based study of SE in Auckland, New Zealand (NZ) over 1 year, with data recorded in the EpiNet database. Focus on treatment patterns and determinants of SE duration and 30‐day mortality. The incidence, etiology, ethnic discrepancies, and seizure characteristics of this cohort have been published previously. Results: A total of 365 patients were included in this treatment cohort; 326 patients (89.3%) were brought to hospital because of SE, whereas 39 patients (10.7%) developed SE during a hospital admission for another reason. Overall, 190 (52.1%) had a known history of epilepsy and 254 (70.0%) presented with SE with prominent motor activity. The mean Status Epilepticus Severity Score (STESS) was 2.15 and the mean SE duration of all patients was 44 min. SE self‐terminated without any treatment in 84 patients (22.7%). Earlier administration of appropriately dosed benzodiazepine in the pre‐hospital setting was a major determinant of SE duration. Univariate analysis demonstrated that mortality was significantly higher in older patients, patients with longer durations of SE, higher STESS, and patients who developed SE in hospital, but these did not maintain significance with multivariate analysis. There was no difference in the performance of the health care system in the treatment of SE across ethnic groups. Significance: When SE was defined as 10 continuous minutes of seizure, overall mortality was lower than expected and many patients had self‐limited presentations for which no treatment was required. Although there were disparities in the incidence of SE across ethnic groups there was no difference in treatment or outcome. The finding highlights the benefit of a health care system designed to deliver universal health care. [ABSTRACT FROM AUTHOR]

Background: Bayesian methods are increasing in popularity in clinical research. The design of Bayesian clinical trials requires a prior distribution, which can be elicited from experts. In diseases with international differences in management, the elicitation exercise should recruit internationally, making a face-to-face elicitation session expensive and more logistically challenging. Thus, we used a remote, real-time elicitation exercise to construct prior distributions. These elicited distributions were then used to determine the sample size of the Bronchiolitis in Infants with Placebo Versus Epinephrine and Dexamethasone (BIPED) study, an international randomised controlled trial in the Pediatric Emergency Research Network (PERN). The BIPED study aims to determine whether the combination of epinephrine and dexamethasone, compared to placebo, is effective in reducing hospital admission for infants presenting with bronchiolitis to the emergency department.Methods: We developed a Web-based tool to support the elicitation of the probability of hospitalisation for infants with bronchiolitis. Experts participated in online workshops to specify their individual prior distributions, which were aggregated using the equal-weighted linear pooling method. Experts were then invited to provide their comments on the aggregated distribution. The average length criterion determined the BIPED sample size.Results: Fifteen paediatric emergency medicine clinicians from Canada, the USA, Australia and New Zealand participated in three workshops to provide their elicited prior distributions. The mean elicited probability of admission for infants with bronchiolitis was slightly lower for those receiving epinephrine and dexamethasone compared to supportive care in the aggregate distribution. There were substantial differences in the individual beliefs but limited differences between North America and Australasia. From this aggregate distribution, a sample size of 410 patients per arm results in an average 95% credible interval length of less than 9% and a relative predictive power of 90%.Conclusion: Remote, real-time expert elicitation is a feasible, useful and practical tool to determine a prior distribution for international randomised controlled trials. Bayesian methods can then determine the trial sample size using these elicited prior distributions. The ease and low cost of remote expert elicitation mean that this approach is suitable for future international randomised controlled trials.Trial Registration: ClinicalTrials.gov NCT03567473.

Objective: To determine the prevalence of fever phobia among caregivers of children presenting to New Zealand EDs. Methods: A cross‐sectional survey was administered to caregivers of children <5 years of age presenting to three New Zealand EDs. We defined fever phobia as caregivers having a high level of concern regarding fever or having incorrect beliefs regarding the consequences of fever. Results: A total of 502 caregivers completed the survey. Fever phobia was present in 365 (74.3% [95% confidence interval, CI 70.3–78.0%]) respondents, with 242 (49.3% [95% CI 44.9–53.7%]) caregivers reporting a high level of concern regarding fever, and 288 (61.8% [95% CI 57.3–66.1%]) caregivers reporting at least one incorrect belief regarding the consequences of fever. Majority of caregivers (n = 383, 87.6% [95% CI 84.2–90.4%]) knew the correct dosing interval for paracetamol, compared to less than half of caregivers (n = 179, 42.5% [95% CI 37.9–47.3%]) for ibuprofen. Caregivers reported non‐evidence‐based fever management practices such as sponging, always giving paracetamol and/or ibuprofen for fever, and waking children from sleep to give antipyretics. Over one‐third of caregivers identified ED doctors (n = 195, 40.2% [95% CI 34.7–43.2%]) and ED nurses (n = 173, 35.7% [95% CI 31.5–40.0%]) as sources of information regarding fever management. A higher level of education was associated with fever phobia (odds ratio 1.68 [95% CI 1.04–2.72], P = 0.04). Conclusions: Fever phobia is prevalent among caregivers of children presenting to New Zealand EDs. Opportunistic caregiver education in the ED in conjunction with public health strategies are needed to dispel undue fears and misconceptions about fever. [ABSTRACT FROM AUTHOR]

Background: Antenatal corticosteroids for women at risk of preterm birth reduce neonatal morbidity and mortality, but there is limited evidence regarding their effects on long-term health. This study assessed cardiovascular outcomes at 50 years after antenatal exposure to corticosteroids. Methods and findings: We assessed the adult offspring of women who participated in the first randomised, double-blind, placebo-controlled trial of antenatal betamethasone for the prevention of neonatal respiratory distress syndrome (RDS) (1969 to 1974). The first 717 mothers received 2 intramuscular injections of 12 mg betamethasone or placebo 24 h apart and the subsequent 398 received 2 injections of 24 mg betamethasone or equivalent volume of placebo. Follow-up included a health questionnaire and consent to access administrative data sources. The co-primary outcomes were the prevalence of cardiovascular risk factors (any of hypertension, hyperlipidaemia, diabetes mellitus, gestational diabetes mellitus, or prediabetes) and age at first major adverse cardiovascular event (MACE) (cardiovascular death, myocardial infarction, coronary revascularisation, stroke, admission for peripheral vascular disease, and admission for heart failure). Analyses were adjusted for gestational age at entry, sex, and clustering. Of 1,218 infants born to 1,115 mothers, we followed up 424 (46% of survivors; 212 [50%] female) at mean (standard deviation) age 49.3 (1.0) years. There were no differences between those exposed to betamethasone or placebo for cardiovascular risk factors (159/229 [69.4%] versus 131/195 [67.2%]; adjusted relative risk 1.02, 95% confidence interval [CI] [0.89, 1.18;]; p = 0.735) or age at first MACE (adjusted hazard ratio 0.58, 95% CI [0.23, 1.49]; p = 0.261). There were also no differences in the components of these composite outcomes or in any of the other secondary outcomes. Key limitations were follow-up rate and lack of in-person assessments. Conclusions: There is no evidence that antenatal corticosteroids increase the prevalence of cardiovascular risk factors or incidence of cardiovascular events up to 50 years of age. Established benefits of antenatal corticosteroids are not outweighed by an increase in adult cardiovascular disease. Anthony G B Walters and colleagues assess cardiovascular outcomes fifty years after antenatal exposure to betamethasone, in long-term follow-up of a randomised double-blind, placebo-controlled trial. Author summary: Why was this study done?: Antenatal corticosteroids (ANC) are given to pregnant persons at risk of preterm birth to reduce the risk of death and breathing difficulty for their offspring. Animal studies have shown later adverse effects of ANC on offspring, particularly on their cardiovascular health in adulthood. There is little robust evidence about long-term effects in humans. This study aimed to provide evidence about the long-term effects of ANC on offspring cardiovascular health in adulthood. What did the researchers do and find?: We assessed participants at 50 years of age who had been exposed to ANC or placebo during the first randomised clinical trial of this treatment. We compared cardiovascular disease and cardiovascular risk factors between those exposed to ANC and placebo in 424 participants (46% of those still alive), using a questionnaire and routinely collected administrative data. We found no differences in cardiovascular outcomes between those exposed to ANC and those who were not. What do these findings mean?: There is no evidence that ANC has adverse effects on the cardiovascular health outcomes of offspring up to 50 years of age. The main limitation was the follow-up rate of less than 50% and the use of health questionnaires and routinely collected data rather than in-person assessments. [ABSTRACT FROM AUTHOR]

Aim: To understand and evaluate the uptake and local adaptations of proven targeted implementation interventions that have effectively reduced unnecessary investigations and therapies in infants with bronchiolitis within emergency departments. Methods: A multi‐centred, mixed‐methods quality improvement study in four Australian hospitals that provide paediatric emergency and inpatient care from May to December 2021. All hospitals were provided with the same implementation intervention package and training. Real‐time tracking logs of adaptions were completed followed by semi‐structured interviews. Interviews were recorded, transcribed and subsequently coded using FRAME‐IS to further describe the adaptions made. Results: Tracking logs were summarised and data from 12 interviews were compared from participating sites. The intervention resulted in 116 education sessions and a total of 23 adaptations made to educational materials, both content and contextual. Shortening education presentations, addition of bronchiolitis definitions, formatting of materials and novel interventions were the most common modifications. Audit and feedback were completed across all sites with varying utilisation. Targeted teaching was noted to dictate adaptions prior to and during implementation. Conclusion: Quantitative and qualitative analysis of clinical 'real‐world' adaptations to proven targeted implementation interventions allows invaluable insight for future de‐implementation initiatives and national roll‐out of implementation packages in the ED setting.

Information on the medium-term recovery of children with Bell palsy or acute idiopathic lower motor neuron facial paralysis is limited. We followed up children aged 6 months to <18 years with Bell palsy for 12 months after completion of a randomized trial on the use of prednisolone. We assessed facial function using the clinician-administered House-Brackmann scale and the modified parent-administered House-Brackmann scale. One hundred eighty-seven children were randomized to prednisolone (n = 93) or placebo (n = 94). At six months, the proportion of patients who had recovered facial function based on the clinician-administered House-Brackmann scale was 98% (n = 78 of 80) in the prednisolone group and 93% (n = 76 of 82) in the placebo group. The proportion of patients who had recovered facial function based on the modified parent-administered House-Brackmann scale was 94% (n = 75 of 80) vs 89% (n = 72 of 81) at six months (OR 1.88; 95% CI 0.60, 5.86) and 96% (n = 75 of 78) vs 92% (n = 73 of 79) at 12 months (OR 3.12; 95% CI 0.61, 15.98). Although the vast majority had complete recovery of facial function at six months, there were some children without full recovery of facial function at 12 months, regardless of prednisolone use.

Aim: To evaluate the impact of locally adapted targeted implementation interventions on bronchiolitis management through reduction in ineffective investigation and therapies within emergency departments. Methods: A multi‐centred, quality improvement study in four different grades of hospitals in Western Australia that provide paediatric emergency and inpatient care. All hospitals incorporated an adapted implementation intervention package for infants under 1 year with bronchiolitis. The proportion whose care complied with guideline recommendations to not receive investigations and therapies of minimal benefit were compared to pre‐intervention care in a previous bronchiolitis season. Results: A total of 457 infants in 2019 (pre‐intervention) and 443 in 2021 (post‐intervention) were included, with mean age of 5.6 months (SD 3.2, 2019; SD 3.0, 2021). In 2019, compliance was 78.1% versus 85.6% in 2021, RD 7.4 (95% CI −0.6; 15.5). The strongest evidence was reduced salbutamol use (compliance improvement: 88.6% to 95.7%, RD 7.1 95% CI (1.7; 12.4)). Hospitals initially at <80% compliance demonstrated greatest improvements (Hospital 2: 95 (78.5%) to 108 (90.8%) RD 12.2 95% CI (3.3; 21.2); Hospital 3: 67 (62.6%) to 63 (76.8%) RD 14.2 95% CI (1.3; 27.2)). Conclusion: Targeted site‐adapted implementation interventions resulted in improvement in compliance with guideline recommendations, particularly for those hospitals with initial low compliance. Maximising benefits through guidance on how to adapt and effectively use interventions will enhance sustainable practice change. [ABSTRACT FROM AUTHOR]

Background: There is limited evidence on the use of facial nerve function grading scales in acute facial nerve paralysis in children. Objective: To investigate the agreement between and the usability of the House-Brackmann and Sunnybrook scales in children with idiopathic facial paralysis (Bell's palsy) and to compare their ease of administration. Methods: Data from a randomized controlled trial in children aged 6 months to <18 years with Bell's palsy was used. Children were recruited within 72 hours of symptom onset and assessed using the House-Brackmann and the Sunnybrook scales at baseline and at 1, 3, and 6 months until recovered. Agreement between the scales was assessed using the intraclass correlation coefficient (ICC) at each time point and using a Bland-Altman plot. Ease of administration was assessed using an 11-point Likert scale. Results: Comparative data were available for 169 of the 187 children randomized. The ICC between the 2 scales across all time points was 0.92 (95% confidence interval [CI] 0.91-0.93), at baseline 0.37 (95% 0.25, 0.51), at 1 month 0.91 (95% CI 0.89-0.94), at 3 months 0.85 (95% CI 0.80-0.89), and at 6 months 0.96 (95% CI 0.95-0.97). The median score for the ease of administration for the House-Brackmann and Sunnybrook scales was 3 (interquartile range [IQR]: 1-5) and 7 (IQR: 4-8) respectively (P <.001, Wilcoxon signed-rank test). Conclusions: There was excellent agreement between House-Brackmann and Sunnybrook scales, with poorer agreement at baseline. Clinicians found the House-Brackmann scale easier to administer. These findings suggest that both scales can be applied in children. [ABSTRACT FROM AUTHOR]

Aim: To determine the prevalence of high flow nasal cannula (HFNC) therapy in infants presenting to hospital in Australia and New Zealand with bronchiolitis over four bronchiolitis seasons. Secondary aims were to determine temporal trends in HFNC use, and associations between HFNC, hospital length of stay (LOS) and intensive care unit (ICU) admission. Methods: A planned sub‐study of a multi‐centre international cluster randomised controlled trial investigating knowledge translation strategies for a bi‐national bronchiolitis guideline. Demographics, management and outcomes data were collected retrospectively for infants presenting with bronchiolitis to 26 hospitals between 1 May 2014 and 30 November 2017. Prevalence data are presented as absolute frequencies (95% confidence interval (CI)) with differences between groups for continuous and categorical variables analysed using linear and logistic regression, respectively. Results: 11 715 infants were included with 3392 (29.0%, 95% CI (28.1–29.8%)) receiving oxygen therapy; of whom 1817 (53.6%, 95% CI (51.9–55.3%)) received HFNC. Use of oxygen therapy did not change over the four bronchiolitis seasons (P = 0.12), while the proportion receiving HFNC increased (2014, 336/2587 (43.2%); 2017, 609/3720 (57.8%); P ≤ 0.001). Infants who received HFNC therapy were not substantially different to infants who received oxygen therapy without HFNC. HFNC use was associated with increases in both hospital LOS (P < 0.001) and ICU admissions (P < 0.001). Conclusion: Use of HFNC therapy for infants with bronchiolitis increased over 4 years. Of those who received oxygen therapy, the majority received HFNC therapy without improvement in hospital LOS or ICU admissions. Strategies to guide appropriate HFNC use in infants with bronchiolitis are required. [ABSTRACT FROM AUTHOR]

Objectives: To assess (i) paediatric fever management practices among New Zealand ED doctors and nurses, including adherence to best practice guidelines; and (ii) the acceptability of a randomised controlled trial (RCT) of antipyretics for relief of discomfort in young children. Methods: A cross‐sectional survey of doctors and nurses across 11 New Zealand EDs. The primary outcome of adherence to paediatric fever management best practice guidelines was assessed with clinical vignettes and defined as single antipyretic use for the relief of fever‐related discomfort. Results: Out of 602 participants (243 doctors, 353 nurses and six unknown; response rate 47.5%), only 64 (10.6%, 95% confidence interval [CI] 8.3–13.4%) demonstrated adherence to best practice guidelines. In a febrile settled child with normal fluid intake, the percentage of participants that would use antipyretics doubled with abnormal vital signs (33.7% vs 72.9%, difference −39.2%, 95% CI –44.4% to −34.0%). Most participants would use antipyretics for reduced fluid intake (n = 494, 82.1%, 95% CI 78.8–85.0%) in a febrile settled child. Over half (n = 339, 57.1%, 95% CI 53.0–61.1%) would advise giving antipyretics to prevent febrile convulsions. Most (n = 467, 80.0%, 95% CI 76.5–83.1%) participants agreed that a RCT of antipyretics in febrile children <2 years of age with relief of discomfort as a primary outcome is needed. Conclusions: Just over 10% of New Zealand ED doctors and nurses demonstrated adherence to paediatric fever management best practice guidelines. A RCT of antipyretics in febrile children <2 years of age specifically addressing relief of discomfort as a primary outcome is strongly supported. [ABSTRACT FROM AUTHOR]

Aim: To explore factors influencing fever management practices and antipyretic use among New Zealand Emergency Department (ED) doctors and nurses using the Theoretical Domains Framework (TDF).Methods: Cross-sectional survey of doctors and nurses across 11 New Zealand EDs. The questionnaire examined eight of 12 TDF domains, based on a generic questionnaire validated to assess TDF-based determinants of health-care professional behaviour. Relevant domains were identified by the frequency of beliefs; the presence of conflicting beliefs within a domain; and the likely strength of impact of a belief on paediatric fever management in the ED.Results: About 602 participants (243 doctors, 353 nurses and 6 unknown) completed the survey (response rate 47.5%). Over half (351/591, 59.6%, 95% confidence interval (CI) 55.5-63.5%) knew the content of clinical practice guidelines regarding antipyretic use in febrile children (TDF Domain Knowledge), or had been trained to ensure antipyretics are given to febrile children only if they appear distressed (347/592, 58.6%, 95% CI 54.5-62.6%) (Skills). Over 40% (246/590, 95% CI 37.7-45.8%) aim to reduce the fever before discharge (Goals). Most (444/591, 75.1%, 95% CI 71.4-78.6%) participants felt capable of explaining appropriate antipyretic use to parents/care givers (Beliefs about Capabilities). Only a minority (155/584, 26.5%, 95% CI 23.0-30.3%) thought that they can ensure antipyretics are given to febrile children only if they appear distressed when the ED is busy (Environmental Context and Resources).Conclusions: Using the TDF, we identified factors influencing fever management practices and antipyretic use in the ED. These factors can guide the design of targeted, theory-informed knowledge translation strategies. [ABSTRACT FROM AUTHOR]

Objective: Paediatric status epilepticus (SE) has potential for long‐term sequelae. Existing data demonstrate delays to aspects of care. The objective of the present study was to examine the feasibility of collecting data on children with paediatric SE and describe current management strategies in pre‐hospital and in‐hospital settings. Methods: A pilot, prospective, observational cohort study of children 4 weeks to 16 years of age with SE, in four EDs in Australia. Clinical details including medications administered, duration of seizure and short‐term outcomes were collected. Follow up occurred by telephone at 1 month. Results: We enrolled 167 children with SE. Mean age was 5.4 years (standard deviation [SD] 4.1), and 81 (49%) male. Median seizure duration was 10 min (interquartile range 7–30). Midazolam was the first medication administered in 87/100 (87%) instances, mean dose of 0.21 mg/kg (SD 0.13). The dose of midazolam was adequate in 30 (35%), high (>0.2 mg/kg) in 44 (51%) and low (<0.1 mg/kg) in 13 (15%). For second‐line agents, levetiracetam was administered on 33/55 (60%) occasions, whereas phenytoin and phenobarbitone were administered on 11/55 (20%) occasions each. Mean dose of levetiracetam was 26.4 mg/kg (SD 13.5). One hundred and four (62%) patients were admitted to hospital, with 13 (8%) admitted to ICU and seven (4%) intubated. Conclusion: In children presenting with SE in Australia medical management differed from previous reports, with midazolam as the preferred benzodiazepine, and levetiracetam replacing phenytoin as the preferred second‐line agent. This pilot study indicates the feasibility of a paediatric SE registry and its utility to understand and optimise practice. [ABSTRACT FROM AUTHOR]

Objective: Recent trials provide high-quality evidence for second-line treatment of convulsive status epilepticus (CSE) in children. However, the most effective medications for other seizure emergencies are poorly understood without established treatment algorithms. We investigated children presenting to the emergency department with repetitive or prolonged convulsions who required intravenous long-acting antiseizure medications, to determine the relative importance and treatment responsiveness of status epilepticus and seizure clusters. Methods: Retrospective observational study in the emergency department, Royal Children's Hospital, Melbourne, Australia (annual census 90 000) using hospital electronic medical records data of patients presenting with seizures in 2018. For patients receiving parenteral long-acting antiseizure medications, seizures were categorized as convulsive status epilepticus, nonconvulsive status epilepticus, and seizure clusters. Results: 1468 patients (2% of all visits) presented with seizures to the emergency department in 2018. Long-acting antiseizure medications were administered to 97 (7%) children for the emergency management of seizures. The majority presented with seizure clusters (n = 69; 71%). Only 11 (11%) were in convulsive status epilepticus and 17 (18%) in nonconvulsive status epilepticus. In convulsive status epilepticus, nonconvulsive status epilepticus, and seizure clusters, phenytoin was used in 27%, 53%, and 58% and levetiracetam in 73%, 47%, and 32%, respectively. Conclusions: Convulsive status epilepticus represents a small portion of patients requiring parenteral long-acting antiseizure medications. Seizure clusters accounted for >6 times the number of convulsive status epilepticus, yet evidence and treatment algorithms are lacking. [ABSTRACT FROM AUTHOR]

Aim: This study aimed to determine whether targeted interventions, proven to be effective at improving evidence‐based bronchiolitis management, changed factors previously found to influence variation in bronchiolitis management. Methods: This survey assessed change in factors influencing clinicians' (nurses and doctors) bronchiolitis management at baseline and post‐intervention in a cluster randomised controlled trial of targeted, theory‐informed interventions aiming to de‐implement non‐evidence‐based bronchiolitis management (no use of chest X‐ray, salbutamol, antibiotics, glucocorticoids and adrenaline). Survey questions addressed previously identified factors influencing bronchiolitis management from six Theoretical Domains Framework domains (knowledge; skills; beliefs about consequences; social/professional role and identity; environmental context and resources; social influences). Data analysis was descriptive. Results: A total of 1958 surveys (baseline = 996; post‐intervention = 962) were completed by clinicians from the emergency department and paediatric inpatient units from 26 hospitals (intervention = 13; control = 13). Targeted bronchiolitis interventions significantly increased knowledge of the Australasian Bronchiolitis Guideline (intervention clinicians = 74%, control = 39%, difference = 34.7%, 95% confidence interval (CI) = 25.6–43.8%), improved skills in diagnosing (intervention doctors = 89%, control = 76%, difference = 12.6%, 95% CI = 6.2–19%) and managing bronchiolitis (intervention doctors = 87%, control = 76%, difference = 9.9%, 95% CI = 3.7–16.1%), positively influenced both beliefs about consequences regarding salbutamol use (intervention clinicians = 49%, control = 29%, difference = 20.3%, 95% CI = 13.2–27.4%) and nurses questioning non‐evidence‐based bronchiolitis management (chest X‐ray: intervention = 71%, control = 51%, difference = 20.8%, 95% CI = 11.4–30.2%; glucocorticoids: intervention = 64%, control = 40%, difference = 21.9%, 95% CI = 10.4–33.5%) (social/professional role and identity). A 14% improvement in evidence‐based bronchiolitis management favouring intervention hospitals was demonstrated in the cluster randomised controlled trial. Conclusion: Targeted interventions positively changed factors influencing bronchiolitis management resulting in improved evidence‐based bronchiolitis care. This study has important implications for improving bronchiolitis management and future development of interventions to de‐implement low‐value care. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Decreasing unnecessary cranial computed tomography (CT) use in pediatric head trauma patients remains important for emergency departments (EDs) across the US. Our study evaluated CT use in children with minor blunt head trauma in 21 community EDs within an integrated health-care system. METHODS: We studied all children younger than 18 years old presenting to 21 community EDs between 2016 through 2018 with acute minor blunt head trauma, defined by an algorithm of ED chief complaints and diagnoses. We excluded patients with traumatic brain injuries diagnosed in the prior year, a CT within 24 hours prior to the ED visit, or an ED Glasgow Coma Scale score of less than 14. RESULTS: Among 39,792 pediatric minor head trauma ED visits, the aggregate CT use proportion across all EDs was 12.9% [95% confidence interval (CI), 12.6-13.3%; facility-level range, 5.4-21.6%]. The 7 facilities that had previously received a clinical decision support system intervention implementing the Pediatric Emergency Care Applied Research Network rules during 2013 through 2014 had an aggregate mean CT ordering rate of 11.2% (95% CI, 10.7-11.7%; facility-level range, 5.4-14.3%) compared to 14.1% (95% CI, 13.6-14.5%; facility-level range, 7.3-21.6%) for the nonintervention facilities. CONCLUSION: CT use for children with minor blunt head trauma in the community EDs of an integrated health-care system was low and stable across facilities from 2016 through 2018. This may be indicative of the safe stewardship of resources in the system, including the absence of financial or medicolegal incentives to scan very low-risk patients as well the availability of resources for close patient follow-up.

Background: Bronchiolitis is the most common reason for hospitalisation in infants. All international bronchiolitis guidelines recommend supportive care, yet considerable variation in practice continues with infants receiving non-evidence based therapies. We developed six targeted, theory-informed interventions; clinical leads, stakeholder meeting, train-the-trainer, education delivery, other educational materials, and audit and feedback. A cluster randomised controlled trial (cRCT) found the interventions to be effective in reducing use of five non-evidence based therapies in infants with bronchiolitis. This process evaluation paper aims to determine whether the interventions were implemented as planned (fidelity), explore end-users' perceptions of the interventions and evaluate cRCT outcome data with intervention fidelity data.Methods: A pre-specified mixed-methods process evaluation was conducted alongside the cRCT, guided by frameworks for process evaluation of cRCTs and complex interventions. Quantitative data on the fidelity, dose and reach of interventions were collected from the 13 intervention hospitals during the study and analysed using descriptive statistics. Qualitative data identifying perception and acceptability of interventions were collected from 42 intervention hospital clinical leads on study completion and analysed using thematic analysis.Results: The cRCT found targeted, theory-informed interventions improved bronchiolitis management by 14.1%. The process evaluation data found variability in how the intervention was delivered at the cluster and individual level. Total fidelity scores ranged from 55 to 98% across intervention hospitals (mean = 78%; SD = 13%). Fidelity scores were highest for use of clinical leads (mean = 98%; SD = 7%), and lowest for use of other educational materials (mean = 65%; SD = 19%) and audit and feedback (mean = 65%; SD = 20%). Clinical leads reflected positively about the interventions, with time constraints being the greatest barrier to their use.Conclusion: Our targeted, theory-informed interventions were delivered with moderate fidelity, and were well received by clinical leads. Despite clinical leads experiencing challenges of time constraints, the level of fidelity had a positive effect on successfully de-implementing non-evidence-based care in infants with bronchiolitis. These findings will inform widespread rollout of our bronchiolitis interventions, and guide future practice change in acute care settings.Trial Registration: Australian and New Zealand Clinical Trials Registry: ACTRN12616001567415 .

Background/aims: Despite evidence that preferential use of balanced/buffered fluids may improve outcomes compared with chloride-rich 0.9% saline, saline remains the most commonly used fluid for children with septic shock. We aim to determine if resuscitation with balanced/buffered fluids as part of usual care will improve outcomes, in part through reduced kidney injury and without an increase in adverse effects, compared to 0.9% saline for children with septic shock.Methods: The Pragmatic Pediatric Trial of Balanced versus Normal Saline Fluid in Sepsis (PRoMPT BOLUS) study is an international, open-label pragmatic interventional trial being conducted at > 40 sites in the USA, Canada, and Australia/New Zealand starting on August 25, 2020, and continuing for 5 years. Children > 6 months to < 18 years treated for suspected septic shock with abnormal perfusion in an emergency department will be randomized to receive either balanced/buffered crystalloids (intervention) or 0.9% saline (control) for initial resuscitation and maintenance fluids for up to 48 h. Eligible patients are enrolled and randomized using serially numbered, opaque envelopes concurrent with clinical care. Given the life-threatening nature of septic shock and narrow therapeutic window to start fluid resuscitation, patients may be enrolled under "exception from informed consent" in the USA or "deferred consent" in Canada and Australia/New Zealand. Other than fluid type, all decisions about timing, volume, and rate of fluid administration remain at the discretion of the treating clinicians. For pragmatic reasons, clinicians will not be blinded to study fluid type. Anticipated enrollment is 8800 patients. The primary outcome will be major adverse kidney events within 30 days (MAKE30), a composite of death, renal replacement therapy, and persistent kidney dysfunction. Additional effectiveness, safety, and biologic outcomes will also be analyzed.Discussion: PRoMPT BOLUS will provide high-quality evidence for the comparative effectiveness of buffered/balanced crystalloids versus 0.9% saline for the initial fluid management of children with suspected septic shock in emergency settings.Trial Registration: PRoMPT BOLUS was first registered at ClinicalTrials.gov ( NCT04102371 ) on September 25, 2019. Enrollment started on August 25, 2020. [ABSTRACT FROM AUTHOR]

Aim: Describe paediatricians' experience of adverse health outcomes for children during the New Zealand‐wide level 4 lockdown in response to the COVID‐19 pandemic. Methods: Weekly national survey of paediatricians with an open‐ended questionnaire. Results: During the 6‐week study survey period, the New Zealand Paediatric Surveillance Unit received 33 reports about 55 instances where paediatricians believed care may have been compromised, about half (56%) relating to infants aged from birth to 6 weeks. Compromised care was for acute presentations in 75%, acute complications of a chronic illness in 14%, with 11% for chronic conditions. Paediatricians reported the outcome as moderately severe (short‐term morbidity, increased length of stay, higher level of care) in 38 cases (69%) and in a further 4 (7%) as severe (potential to be life‐threatening or result in permanent disability). Conclusion: Despite clear messaging, hospital avoidance and reduced access to primary and secondary care were associated with significant potential harm for children in New Zealand during a strict lockdown, with newborn infants disproportionately affected. During the implementation of interventions to eliminate community transmission of COVID‐19, New Zealand paediatricians note the importance of face‐to‐face post‐natal visits for newborns and primary care services for children with acute illness, to avoid preventable harm.

Background: Despite international guidelines providing evidence-based recommendations on appropriate management of infants with bronchiolitis, wide variation in practice occurs. This results in infants receiving care of no benefit, with associated cost and is potentially harmful. Theoretical frameworks are increasingly used to develop interventions, utilising behaviour change techniques specifically chosen to target factors contributing to practice variation, with de-implementation often viewed as harder than implementing. This paper describes the stepped process using the Theoretical Domains Framework (TDF) to develop targeted, theory-informed interventions which subsequently successfully improved management of infants with bronchiolitis by de-implementing ineffective therapies. Explicit description of the process and rationale used in developing de-implementation interventions is critical to dissemination of these practices into real world clinical practice.Methods: A stepped approach was used: (1) Identify evidence-based recommendations and practice variation as targets for change, (2) Identify factors influencing practice change (barriers and enablers) to be addressed, and (3) Identification and development of interventions (behaviour change techniques and methods of delivery) addressing influencing factors, considering evidence of effectiveness, feasibility, local relevance and acceptability. The mode of delivery for the intervention components was informed by evidence from implementation science systematic reviews, and setting specific feasibility and practicality.Results: Five robust evidence-based management recommendations, targeting the main variation in bronchiolitis management were identified: namely, no use of chest x-ray, salbutamol, glucocorticoids, antibiotics, and adrenaline. Interventions developed to target recommendations addressed seven TDF domains (identified following qualitative clinician interviews (n = 20)) with 23 behaviour change techniques chosen to address these domains. Final interventions included: (1) Local stakeholder meetings, (2) Identification of medical and nursing clinical leads, (3) Train-the-trainer workshop for all clinical leads, (4) Local educational materials for delivery by clinical leads, (5) Provision of tools and materials targeting influencing factors, and prompting recommended behaviours, and (6) Audit and feedback.Conclusion: A stepped approach based on theory, evidence and issues of feasibility, local relevance and acceptability, was successfully used to develop interventions to improve management of infants with bronchiolitis. The rationale and content of interventions has been explicitly described allowing others to de-implement unnecessary bronchiolitis management, thereby improving care. [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.
