Aim Methods Results Conclusions To characterise key features of young people presenting to the emergency department (ED) with a mental health complaint when comparing children (aged 7 to 12 years) and teenagers (13 years and greater).Retrospective review of all ED mental health presentations in children aged 7–17 years presenting over a 12‐month period in 2018 to a tertiary children's hospital in Victoria, Australia. Univariate analyses were carried out to examine the relationship between children and teenagers and a number of key presentation variables. Odds Ratios (ORs) and 95% Confidence Intervals (CIs) were calculated for ED management outcomes.There were 1691 ED mental health presentations in 2018. Of these presentations, 407 (24%) were children aged 12 years or less. The remaining 76% (1284) were teenagers. The younger aged cohort were more likely to be male (OR 2.43, CI 1.92–3.08) and have a past history of autism spectrum disorder (OR 1.92, CI 1.45–1.84). They were more likely to have a presenting complaint of acute behavioural disturbance (OR 2.03, CI 1.59–2.60), be physically restrained (OR 2.01, CI 1.18–3.37) and have sedative medication provided (OR 2.87, CI 1.63–5.04). The older aged cohort were more likely to have a past history of depression (OR 0.19, CI 0.12–0.29) and a presenting complaint of intentional self‐poisoning (OR 0.33, CI 0.15–0.65).Children aged 12 years or less represent one‐quarter of all young people presenting to the ED with a mental health concern. They experience high rates of acute behavioural disturbance and are more likely to require restrictive interventions during their presentation. [ABSTRACT FROM AUTHOR]

Objective: To describe the effects of different induction agents on the incidence of post‐induction hypotension (PIH) and its associated interventions during rapid sequence intubation (RSI) in the ED. Methods: A single centre retrospective study of patients intubated between 2018 and 2021 was conducted in a regional Australian ED. The impact of induction agent choice, in addition to demographic and clinical factors on the incidence of PIH were determined using descriptive statistics and a multivariate analysis presented as adjusted odds ratios (aORs) and their 95% confidence intervals (CIs). Results: Ketamine and propofol, used either individually or in conjunction with fentanyl, were significantly associated with PIH (ketamine aOR 4.5, 95% CI 1.35–14.96; propofol aOR 4.88, 95% CI 1.46–16.29). Age >60 years was associated with a greater requirement for vasopressors (aOR 4.46, 95% CI 2.49–7.97) and a higher risk of mortality after RSI (aOR 4.2, 95% CI 1.87–9.40). Patients with a shock index >1.0 were significantly more likely to require vasopressors (aOR 5.13, 95% CI 2.35–11.2) and have a cardiac arrest within 15 min of RSI (aOR 3.56, 95% CI 1.07–11.8). Conclusions: Exposure to both propofol and ketamine is significantly associated with PIH after RSI, alongside age and shock index. PIH is likely multifactorial in nature, and this data supports the sympatholytic effect of induction agents as the underlying cause of PIH rather than the choice of agent itself. Further prospective work including a randomised controlled trial between induction agents is justified to further clarify this important clinical question. [ABSTRACT FROM AUTHOR]

Objective: Acute severe behavioural disturbance (ASBD) is a condition seen with increasing frequency in EDs. It poses a significant risk to the patient and those around them. Little is known about the epidemiology or most effective management in the paediatric population. The aim of the present study is to clarify the practice of senior emergency doctors in Australia when managing paediatric ASBD. Methods: The present study was a voluntary electronic questionnaire distributed to and undertaken by senior medical staff in EDs affiliated with the Paediatric Research in Emergency Departments International Collaborative (PREDICT) network. Respondents reported on exposure to and confidence in managing paediatric ASBD and their current practices. Results: A total of 227 (33%) clinicians completed the survey between February and May 2020. Most clinicians were caring for at least two young people with ASBD each week (72%), felt confident regarding the majority of components of management and referred to local clinical practice guidelines (69%). Agitation/sedation rating scales were seldom used (19%). There was a significant variation in self‐reported management practices. The choice of whether to use medication at all, the medication chosen and route of administration all varied greatly. Respondents were more willing to provide parenteral medication to young people reported as having recreational drug intoxication (84%) than those with neurodevelopment disorders (65%) when the same degree of agitation was reported. Conclusions: Within Australia, there is considerable variation in paediatric ASBD practice, in particular regarding medication provision. Further prospective research is required to inform best clinical practice. [ABSTRACT FROM AUTHOR]

Objectives: With an increasingly dynamic global illicit drug market, including the emergence of novel psychoactive substances, many jurisdictions have moved to establish toxicosurveillance systems to enable timely detection of harmful substances in the community. This paper describes the methodology for the Emerging Drugs Network of Australia - Victoria (EDNAV) project, a clinical registry focused on the collection of high-quality clinical and analytical data from ED presentations involving illicit drug intoxications. Drug intelligence collected from the project is utilised by local health authorities with the aim to identify patterns of drug use and emerging drugs of concern. Methods: The project involves 10 public hospital EDs in Victoria, Australia. Patients 16 years and over, presenting to a network ED with a suspected illicit drug-related toxicity and a requirement for venepuncture are eligible for inclusion in the study under a waiver of consent. Clinical and demographic parameters are documented by site-based clinicians and comprehensive toxicological analysis is conducted on patient blood samples via specialised forensic services. All data are then deidentified and compiled in a project specific database. Results: Cases are discussed in weekly multidisciplinary team meetings, with a view to identify potentially harmful substances circulating in the community. High-risk signals are escalated to key stakeholders to produce timely and proportionate public health alerts with a focus on harm minimisation. Conclusions: The EDNAV project represents the first centralised system providing near real-time monitoring of community drug use in Victoria and is fundamental in facilitating evidencebased public health intervention.

Background: Iatrogenic medication errors are a cause of medical morbidity and mortality. They result in significant cost to the Australian healthcare system each year. There is limited Australian evidence describing the iatrogenic errors occurring within the hospital system. Aims: To examine and describe iatrogenic medication errors occurring in Victorian healthcare settings through the analysis of referrals to a state Poisons Information Centre (PIC). Methods: A retrospective review of iatrogenic medication errors reported to the Victorian PIC (VPIC) from community and hospital healthcare settings from January 2015 to December 2019. Results: Over a 5-year period, 357 iatrogenic errors were identified, 63% (n = 224) of which occurred in a hospital setting. The remaining errors occurred in a community healthcare setting. One in five patients were symptomatic from the medication error at the time of the call to the VPIC, and a change in management was required in 45% (n = 165) of all cases. Five percent (n = 17) of patients developed moderate to severe clinical toxicity as determined by the recorded poisoning severity score, and 88% (n = 18) of these required critical care management. Incorrect medication dosing accounted for 62% (n = 221) of errors. Common medication dosing errors included: double dose (51%, n = 114), incorrect medication administered (14%, n = 49), incorrect route (9%, n = 31), incorrect patient (6%, n = 22) and adult dose given to a child (4%, n = 15). Conclusions: Iatrogenic errors are occurring in the Victorian health care system. These errors can result in serious morbidity. Identification of causative factors and investment in preventative strategies will likely reduce associated morbidity and healthcare costs. [ABSTRACT FROM AUTHOR]

Klinefelter syndrome (KS) is a common genetic condition that is currently under-diagnosed. The phenotype is broad, with physical, medical and psychosocial features ranging from mild to severe. When a child is diagnosed with KS, the parents may spend months to years searching for a diagnosis. This study used a qualitative methods approach to explore parents' experiences of having a child with KS and receiving a diagnosis. Fifteen semistructured one-to-one in-depth interviews were conducted to explore their experiences and views. The interviews were then transcribed, coded and thematically analysed. The interviews revealed that parents had diverse experiences related to: the timing of the diagnosis of their child and reasons why their child was investigated for KS; the information that was provided at the time of diagnosis; the supports that were available and the concerns that parents held for the future of their child. The conclusions from this study were that parents' experiences of having a child with KS and receiving a diagnosis were complex and multifaceted. This experience was shaped by the timing of when the diagnosis was received, who provided the diagnosis, what information was provided from health-care professionals and that which parents may have encountered on the internet. The long-term experiences for parents were also impacted by the level of support they received. These findings have implications for the process by which KS is recognised by the health-care community and supports available for families. [ABSTRACT FROM AUTHOR]
