AIM: To evaluate the frequency and predictors of poor outcome in febrile children presenting to the Emergency Department. METHODS: Retrospective observational study from the Emergency Department of The Royal Children's Hospital, Melbourne, Australia. All children with presenting complaint of fever or triage temperature >38°C over a 6-month period were included. Poor outcome was defined as: new organ dysfunction or the requirement for organ support therapy (inotrope infusion, mechanical ventilation, renal replacement therapy and extra-corporeal life support). Predictors evaluated were as follows: initial vital signs, blood tests and clinical scores. Odds ratio, sensitivity, specificity and area under the receiver-operating characteristics curve were calculated for each predictor variable. RESULTS: Between Jan-June 2019, 6217 children met inclusion criteria. Twenty-seven (0.4%) developed new organ dysfunction, 10 (0.2%) required organ support therapy (inotrope infusion in 5, mechanical ventilation in 6, renal replacement therapy in 1, extra-corporeal life support in 1). Odds of new organ dysfunction, requirement for inotropic support and mechanical ventilation were higher with abnormal initial vital signs, blood tests and clinical scores, though overall test characteristics were poor due to infrequency. CONCLUSION: Poor outcomes were uncommon among febrile children presenting to the Emergency Department. Vital signs, blood tests and clinical scores were poor predictors.

OBJECTIVE: In 2013, our intubations highlighted a safety gap - only 49% achieved first-pass success without hypoxia or hypotension. NAP4 recommended debriefing after intubation, but limited published methods existed. Primary aim is to implement a feasible process for immediate debriefing and feedback for emergency airway management. Secondary aims are to contribute to reduced frequency of adverse intubation-related events and implement qualitative improvements in patient safety through team reflection and feedback. METHODS: A component of a prospective quality improvement (QI) study over 4 years in the ED of the Royal Children's Hospital, Melbourne, Australia. Debrief and feedback after intubation was one of seven study interventions. Targeted staff training and involvement of departmental leaders occurred. A post-intervention cohort was audited in 2016. Analysis included the Team Emergency Assessment Measure. RESULTS: Immediate post-event debriefing occurred in 39 (85%) of 46 intubations. Debriefing was short (median duration 5 min, interquartile range [IQR] 5-10) and soon after (median time 20 min, IQR 5-60). Commonest location was the resuscitation room (92%), led by the team leader (97%). Commonest barrier preventing immediate debriefing was excessive workload. Two QI process measures were assessed during debriefing (adequate resuscitation, airway plan) and case summaries distributed for 100% of intubations. Performance outcomes included contribution to 78% first-pass success without hypoxia or hypotension. Team reflection prompted changes to environment (signage, stickers), training (skill drills), teamwork and process (communication, clinical event debriefing). CONCLUSION: Structured and targeted debriefing after intubating children in the ED is feasible and contributes to measurable and qualitative improvements in patient safety.

OBJECTIVE: Fixed ratio blood product administration may improve outcomes in trauma patients with massive blood loss. The present study aimed to describe the impact of a major haemorrhage protocol (MHP) on the ratio of blood products administered for paediatric major trauma. METHODS: Retrospective observational study in a state-designated paediatric major trauma centre in Melbourne, Australia. Children with major trauma who received blood products in the ED were identified from a hospital trauma registry. Blood product ratios before, during and after implementation of a hospital MHP were compared in consecutive 2 year blocks. RESULTS: Over a 6 year period, 767 major trauma patients were identified, of whom 47 received blood products in the ED and were included in the analysis; 14 pre-MHP implementation, 24 during-MHP implementation and nine post-MHP implementation. No patients received blood products at a ratio of 1:1:1 for red blood cells:fresh frozen plasma:platelets, respectively, during any time period. In this cohort of predominantly blunt trauma, blood products were infrequently administered in the ED because of the low prevalence of massive blood loss. Coagulopathy and hypofibrinogenaemia were commonly observed, nearly half of included patients were managed operatively and one quarter did not survive their injuries. CONCLUSION: The implementation of a MHP did not change the ratio of blood product administration in this cohort of patients because of the infrequency of massive blood loss. Future studies may focus on the impact of treating coagulopathy and hypofibrinogenaemia on patient-centred outcomes.

OBJECTIVE: Intubation of children in the emergency setting is a high-risk, low incidence event. Standardisation of clinical practice has been hampered by a lack of high-quality evidence to support one technique over another. The aim of the present study is to determine clinician preference in intubation practice of children in EDs and ICUs in Australia and New Zealand to provide baseline information to allow future targeted research focused on improving the safety and efficacy of paediatric emergency airway management. METHODS: The present study was a voluntary questionnaire undertaken by medical staff at registrar level or above in EDs and ICUs associated with the Paediatric Research in Emergency Departments International Collaborative (PREDICT) and Australia and New Zealand Intensive Care Society Paediatric Study Group (ANZICS PSG) research networks. Respondents reported on their individual intubation practices, with a focus on pre-oxygenation and apnoeic oxygenation techniques, and the use of video laryngoscopy. RESULTS: A total of 502 clinicians were invited to complete the survey between May and October 2018 with 336 (66.9%) responded. There was marked variation in practice between ED clinicians and ICU clinicians in the techniques used for pre-oxygenation, the frequency of use of apnoeic oxygenation and the reported use of video laryngoscopy. CONCLUSIONS: Within Australia and New Zealand there is considerable variation in paediatric emergency airway clinical practice, in particular with respect to pre-oxygenation, apnoeic oxygenation and use of video laryngoscopy. Definitive clinical trials are required to best inform clinical practice in this area.

OBJECTIVE: To describe the effect of fluid bolus therapy (FBT) on blood pressure in children with sepsis. Secondary outcomes included the effect of FBT on systemic vascular resistance, shock index and shock phenotype (warm or cold). METHODS: This was a prospective observational study in the ED of The Royal Children's Hospital, Melbourne, Australia. Participants were children meeting international consensus criteria for sepsis who received FBT for tachycardia or hypotension. FBT was defined as 10-20 mL/kg of 0.9% saline. Mean blood pressure (MBP) was recorded at baseline, 5 and 60 min after FBT. Total systemic vascular resistance index (TSVRi), shock index, and shock phenotype were derived for each time point. Hypotension was defined as MBP <55 + 1.5 × age (years). Warm shock was defined as TSVRi <800 dyne s/cm5 /m2 . RESULTS: Fifty fluid boluses were recorded in 41 children. Median MBP was 78 mmHg (interquartile range [IQR] 63-86) at baseline, 72 mmHg (IQR 60-82) at 5 min, and 75 mmHg (IQR 66-84) at 60 min. Hypotension was observed in 16% at baseline, 26% at 5 min and 17% at 60 min. Median TSVRi was 1580 dyne s/cm5 /m2 (IQR 1242-2206) at baseline, 1254 dyne s/cm5 /m2 (IQR 1027-1787) at 5 min, and 1850 dyne s/cm5 /m2 (IQR 1265-2140) at 60 min. Median shock index was 1.60 (IQR 1.34-1.90) at baseline, 1.49 (IQR 1.25-1.76) at 5 min and 1.37 (IQR 1.22-1.61) at 60 min. Two percent of cases had warm shock at baseline, 12% at 5 min and 2% at 60 min. CONCLUSIONS: MBP initially decreased following FBT for paediatric sepsis, returning towards baseline over the subsequent 60 min. The utility of FBT for increasing MBP and its effect on patient-centred outcomes in children with sepsis warrants further exploration.

OBJECTIVE: Audit and research projects in the ED are important to improve patient care but can be time and resource consuming. We identified and prioritised audit and research topics among multidisciplinary ED staff to fill perceived knowledge gaps, encourage engagement, reduce duplication and facilitate translation of evidence into clinical practice. METHODS: A two-stage electronic Delphi survey process was undertaken by senior medical, nursing, education and social work staff at the Royal Children's Hospital, Victoria. Survey 1 collected demographic data and audit and research ideas following a series of open-ended questions. Priority themes were defined as those that had more than four responses. Survey 2 used a 7-point Likert ranking of these themes to generate a departmental audit and research prioritisation list. RESULTS: 72/89 (82%) available senior staff responded to survey 1 and 63/83 (76%) responded to survey 2. Survey 1 yielded 208 audit and 130 research topics. Survey 2 established a prioritised list of 17 audit and 14 research topics. Top audit themes were mental healthcare, patient flow, management of sepsis and delays in ED specialist referrals. Top research priorities were the management of sepsis, mental healthcare, management of patients with autism and the management of severe asthma. CONCLUSIONS: This Delphi study has provided departmental audit and research priorities that are perceived to be of importance across the multidisciplinary ED team. This methodology allows strategic allocation of limited resources and may increase staff engagement.

OBJECTIVE: Fluid bolus therapy (FBT) is recommended as the initial form of acute circulatory support for many disease processes. The epidemiology of its use in the ED is unknown. The aim of this study was to assess indications, use patterns and short-term effects of FBT in a paediatric ED. METHODS: Retrospective observational study in the ED of the Royal Children's Hospital, Melbourne, Australia (annual census >90 000) using hospital electronic medical record data for all patients who received an i.v. fluid bolus in the ED over the calendar year 2018 were included in the study. We extracted demographics, indications, volume, content of FBT as well as subsequent vital sign and biochemical changes. RESULTS: One thousand five hundred and thirty-nine fluid boluses were administered to 1343/90 000 children (1.5%), 1185 received 1, 123 received 2, 32 received 3, and 3 received 4 boluses. Fluid bolus volume of 10 mL/kg was used in 45.3%, 20 mL/kg in 35.7%, 500 mL in 6.4% and 1000 mL in 7.1%. The fluid content was 0.9% saline in 99.9% of cases. The most common indications for FBT were: vomiting/diarrhoea (23%), acute febrile illness (11%) and pneumonia or sepsis (10% each). FBT was associated with a reduction in median heart rate by 6 beats per minute (P < 0.01), reduction in mean blood pressure by 3 mmHg (P < 0.01), and reduction in venous lactate by 0.2 mmol/L (P < 0.01). CONCLUSIONS: Fluid bolus therapy is a commonly used intervention in the paediatric ED, most often for dehydration. Variability in indications, dose and effects of FBT warrant further exploration.

Intubation of children outside of the operating room is performed infrequently and is often associated with life-threatening adverse events. This review aims to clarify the contributors to adverse events encountered during intubations outside of the operating room and provide preventative strategies. The primary contributors to adverse events during non-operating room intubations are physiologically and situationally difficult airways; anatomically difficult airways are rare. Systems-based changes, including a shared mental model, standardization in equipment and its location, checklist use, physiological resuscitation prior to resuscitation, dose titration of induction agent, multi-disciplinary team training in the technical and nontechnical aspects of non-operating room intubation, debrief post-real and simulated events, and regular audit of performance all reduce life-threatening intubation-related adverse events in children. Intubation of children outside of the operating room may be performed safely through engagement of all critical care specialties, shared learning, and focus on patient-centered care delivery.

In this series we address important topics for emergency clinicians who either participate in research as part of their work, or use the knowledge generated by research studies. Emergency clinicians are routinely in the position of applying new evidence in clinical practice. With an ever-increasing volume of evidence generated, this can be problematic when studies are conducted in different settings, and include different patient groups, different interventions and different outcomes. This is made even more difficult when the results of primary research studies do not agree. Systematic reviews are becoming increasingly valuable as they appraise and synthesise research findings using a clear methodology, and summarise the results of primary studies. As such, systematic reviews help translate research findings into clinical practice. This paper provides a practical starting point for understanding the steps involved in conducting a systematic review in emergency medicine and will help readers appraise the findings of systematic reviews.

OBJECTIVE: The intent of fluid bolus therapy (FBT) is to increase cardiac output and tissue perfusion, yet only 50% of septic children are fluid responsive. We evaluated respiratory variation of inferior vena cava (IVC) diameter as a predictor of fluid responsiveness. METHODS: A prospective observational study in the ED of The Royal Children's Hospital, Melbourne, Australia. Patients were spontaneously ventilating children treated with FBT for sepsis-induced acute circulatory failure. IVC ultrasound was performed prior to FBT. Trans-thoracic echocardiography was performed prior to, 5 and 60 min after FBT. IVC collapsibility index and stroke distance were calculated by a blinded Paediatric Emergency Physician and blinded Paediatric Cardiologist, respectively. RESULTS: Thirty-nine fluid boluses were recorded in 33 children, 28/39 (72%) of which met criteria for fluid responsiveness at 5 min, which was sustained in 2/28 (7%) of initial fluid responders at 60 min. Sensitivity and specificity (95% confidence interval) of IVC collapsibility index were 0.44 (0.25-0.65) and 0.33 (0.10-0.65) with an area under the receiver operator characteristics curve (95% confidence interval) of 0.38 (0.23-0.55) at 5 min. Test characteristics 60 min after fluid bolus administration were not meaningful because of the infrequency of sustained fluid responsiveness in this patient group. There was no significant correlation between IVC collapsibility and fluid responsiveness at 5 or 60 min. CONCLUSIONS: IVC collapsibility has poor test characteristics for predicting fluid responsiveness in spontaneously ventilating children with sepsis.

BACKGROUND: Emergency airway management is commonly associated with life-threatening hypoxia and hypotension which may be preventable. AIMS: The aim of this quality improvement study was to reduce the frequency of intubation-related hypoxia and hypotension. METHODS: This prospective quality improvement study was conducted over 4 years in the Emergency Department of The Royal Children's Hospital, Melbourne, Australia. A preintervention cohort highlighted safety gaps and was used to design study interventions, including an emergency airway algorithm, standardized airway equipment, a preintubation checklist and equipment template, endtidal carbon dioxide monitoring, postintubation team debriefing, and multidisciplinary team training. Following implementation, a postintervention cohort was used to monitor the impact of study interventions on clinical process and patient outcome. Process measures were as follows: use of a preintubation checklist, verbalization of an airway plan, adequate resuscitation prior to intubation, induction agent dose titration, use of apneic oxygenation, and use of endtidal carbon dioxide to confirm endotracheal tube position. The primary outcome measure was first pass success rate without hypoxia or hypotension. Potential harms from study interventions were monitored. RESULTS: Forty-six intubations were included over one calendar year in the postintervention cohort (compared to 71 in the preintervention cohort). Overall clinical uptake of the 6 processes measures was 85%. First pass success rate without hypoxia or hypotension was 78% in the postintervention cohort compared with 49% in the preintervention cohort (absolute risk reduction: 29.0%; 95% confidence interval 12.3%-45.6%, number needed to treat: 3.5). No significant harms from study interventions were identified. CONCLUSION: Quality improvement initiatives targeting emergency airway management may be successfully implemented in the emergency department and are associated with a reductio

Emergency airway management, particularly outside of the operating room, is associated with a high incidence of life-threatening adverse events. Based on the recommendations of the 4th National Audit Project, we aimed to develop hospital-wide systems changes to improve the safety of emergency airway management. We describe a framework for governance in the form of a hospital airway special interest group. We describe the development and implementation of the following systems changes: 1. A local intubation algorithm modified from the Difficult Airway Society's plan A-B-C-D approach, including clear pathways for airway escalation, and emphasizing the concepts of resuscitation prior to intubation, planning for failure, and avoidance of fixation error. 2. Simplified and standardized airway equipment located in identical airway carts in all critical care areas. 3. A preintubation checklist and equipment template to standardize preparation for airway management. 4. Availability of continuous waveform endtidal capnography in all critical care areas for confirmation of correct endotracheal tube placement. 5. Multidisciplinary team training to address the technical and nontechnical aspects of nonoperating room intubation. In addition, we describe methodology for ongoing monitoring of performance through a quality assurance framework. In conclusion, changes in the process of emergency airway management at a hospital level are feasible through collaboration. Their impact on patient-based outcomes requires further study.

The 'Can't Intubate Can't Oxygenate' emergency is rare in children. Nevertheless, airway clinicians involved in pediatric airway management must be able to rescue the airway percutaneously through the front of the neck should this situation be encountered. Little evidence exists in children to guide rescue techniques, and extrapolation of adult evidence may be problematic due to anatomical differences. This document reviews the currently available evidence, and presents a practical approach to standardizing equipment, techniques, and training for managing the 'Can't Intubate Can't Oxygenate' emergency in children.

Sepsis and septic shock are the final common pathway for many decompensated paediatric infections. Fluid resuscitation therapy has been the cornerstone of haemodynamic resuscitation in these children. Good evidence for equivalence between 0.9% saline and 4% albumin, with the relative expense of the latter, has meant that 0.9% saline is currently the most commonly used resuscitation fluid world-wide. Evidence for harm from the chloride load in 0.9% saline has generated interest in balanced solutions as first line resuscitation fluids. Their safety has been well established in observational studies, and they may well be the most reasonable default fluid for resuscitation. Semi-synthetic colloids have been associated with renal dysfunction and death and should be avoided. There is evidence for harm from excessive administration of any resuscitation fluid. Resuscitation fluid volumes should be treated in the same way as the dose of any other intravenously administered medication, and the potential benefits versus harms for the individual patient weighed prior to administration.

The Social Inclusion Agenda (‘SIA’) was introduced by the Australian Labor Party (‘ALP’) in the lead up to the 2007 federal election. The rhetoric was hopeful, proposing to reframe the government's approach to disadvantage. Rhetoric aside, what the then opposition meant when it talked of building social inclusion (‘SI’) was less clear than may have immediately met the eye. This paper offers an introductory analysis and review of the SIA. It first considers why Australia might benefit from a readjustment in its social policy direction, reflecting on the concepts of poverty and Amartya Sen's ‘capabilities approach‘. Second, it offers a critical overview of the main conceptions of SI/Social Exclusion. Third, it applies these first two parts of analysis to developments to date with the SIA. This part, whilst limited in scope and preliminary at best, offers some general comments as to the possibilities and pitfalls of the SIA and proposes the way forward from an analytical perspective in terms of guiding the SIA in a desirable direction.
