Preventing adverse events during paediatric cancer treatment: protocol for a multi-site hybrid randomised controlled trial of catheter lock solutions (the CLOCK trial).

INTRODUCTION: Central venous access devices (CVADs) are commonly used for the treatment of paediatric cancer patients. Catheter locking is a routine intervention that prevents CVAD-associated adverse events, such as infection, occlusion and thrombosis. While laboratory and clinical data are promising, tetra-EDTA (T-EDTA) has yet to be rigorously evaluated or introduced in cancer care as a catheter lock. METHODS AND ANALYSIS: This is a protocol for a two-arm, superiority type 1 hybrid effectiveness-implementation randomised controlled trial conducted at seven hospitals across Australia and New Zealand. Randomisation will be in a 3:2 ratio between the saline (heparinised saline and normal saline) and T-EDTA groups, with randomly varied blocks of size 10 or 20 and stratification by (1) healthcare facility; (2) CVAD type and (3) duration of dwell since insertion. Within the saline group, there will be a random allocation between normal and heparin saline. Participants can be re-recruited and randomised on insertion of a new CVAD. Primary outcome for effectiveness will be a composite of CVAD-associated bloodstream infections (CABSI), CVAD-associated thrombosis or CVAD occlusion during CVAD dwell or at removal. Secondary outcomes will include CABSI, CVAD-associated-thrombosis, CVAD failure, incidental asymptomatic CVAD-associated-thrombosis, other adverse events, health-related quality of life, healthcare costs and mortality. To achieve 90% power (alpha=0.05) for the primary outcome, data from 720 recruitments are required. A mixed-methods approach will be employed to explore implementation contexts from the perspective of clinicians and healthcare purchasers. ETHICS AND DISSEMINATION: Ethics approval has been provided by Children's Health Queensland Hospital and Health Service Human Research Ethics Committee (HREC) (HREC/22/QCHQ/81744) and the University of Queensland HREC (2022/HE000196) with subsequent governance approval at all sites. Informed consent is required from the substitute decision-maker or legal guardian prior to participation. In addition, consent may also be obtained from mature minors, depending on the legislative requirements of the study site. The primary trial and substudies will be written by the investigators and published in peer-reviewed journals. The findings will also be disseminated through local health and clinical trial networks by investigators and presented at conferences. TRIAL REGISTRATION NUMBER: ACTRN12622000499785.

Nasal High Flow Therapy for Bronchiolitis.

AIM: Uptake of nasal high-flow therapy in infants with bronchiolitis has grown in the last decade with some evidence suggesting a reduction in escalation of care. The effect of the implementation of recent available evidence on clinical practice remains unclear. METHODS: In a prospective observational study over 6 months in six metropolitan hospitals in Australia, we investigated the clinical practice of high-flow in infants admitted with bronchiolitis and an oxygen requirement. To assess the choice by clinicians of the initial oxygen therapy (standard oxygen or high-flow) the disease severity was measured by physiological parameters obtained prior to oxygen therapy commencement. Additional secondary outcomes were hospital length of stay and transfers to intensive care. RESULTS: Two hundred thirty-five infants with bronchiolitis were admitted for oxygen therapy over 6 months during the winter season. Infants who received high-flow on admission to hospital displayed significantly higher respiratory rates, higher heart rates and higher early warning tool scores with more severe work of breathing than those commenced on standard oxygen therapy as a first line of oxygen therapy. A significantly longer hospital length of stay of 0.6 days occurred in infants commenced on high-flow. A significantly greater proportion on high-flow (23.3%) were admitted to intensive care compared to infants commenced on SOT (10.4%) despite the severity of disease in both groups being similar. CONCLUSIONS: Infants with bronchiolitis presenting with greater disease severity are more likely to receive high-flow therapy. Escalation of care in an intensive care unit occurred more frequently on infants on high-flow. TRIAL REGISTRATION: This trial is registered in the Australian New Zealand Clinical Trial Registry ACTRN12618001206213.

Preparing for Death While Investing in Life: A Narrative Inquiry and Case Report of Home-Based Paediatric Palliative, End-of-Life, and After-Death Care.

Paediatric palliative care is pivotal for addressing the complex needs of children with incurable diseases and their families. While home-based care offers a familiar and supportive environment, delivering comprehensive services in this context is challenging. The existing literature on home-based palliative care lacks detailed guidance for its organization and implementation. This qualitative narrative inquiry explores the organization and provision of home-based paediatric palliative care. Data were collected from healthcare practitioners using conversations, storytelling, and reflective journaling. Schwind's Narrative Reflective Process was applied to synthesize the data, resulting in an in-depth case description. The narrative approach illuminates the complexities of home-based paediatric palliative, end-of-life, and after-death care. Key findings encompass the importance of early-care coordination, interprofessional collaboration, effective symptom management, emotional and psychosocial support, and comprehensive end-of-life planning. Through the case study of the child patient, the challenges and strategies for providing holistic, family-centred care within the home environment are described. Practical insights gained from this report can inform the development and improvement of home-based palliative care programs, benefiting researchers, practitioners, and policymakers seeking to optimize care for children and families in similar contexts.

The quality of diagnostic guidelines for children in primary care: A meta-epidemiological study.

AIM: To determine the quality of paediatric guidelines relevant to diagnosis of three of the most common conditions in primary care: fever, gastroenteritis and constipation. METHODS: We undertook a meta-epidemiological study of paediatric guidelines for fever, gastroenteritis and gastroenteritis. We systematically searched MEDLINE, Embase, Trip Database, Guidelines International Network, the National Guideline Clearinghouse and WHO from February 2011 to September 2022 for guidelines from high-income settings containing diagnostic recommendations. We assessed the quality of guideline reporting for included guidelines using the AGREE II tool. RESULTS: We included 16 guidelines: fever (n = 7); constipation (n = 4) and gastroenteritis (n = 5). The overall quality across the three conditions was graded moderate (median AGREE II score 4.5/7, range 2.5-6.5) with constipation guidelines rated the highest (median 6/7), and fever rated the lowest (median 3.8/7). Major methodological weaknesses included consideration of guideline applicability. Half of the guidelines did not report involving parent representatives, and 56% did not adequately declare or address their competing interests. CONCLUSIONS: Substantial variations exist in the quality of paediatric guidelines related to the diagnosis of primary care presentations. Better quality guidance is needed for general practitioners to improve diagnosis for children in primary care.

The quality of paediatric asthma guidelines: evidence underpinning diagnostic test recommendations from a meta-epidemiological study.

BACKGROUND: Asthma is one of the most frequent reasons children visit a general practitioner (GP). The diagnosis of childhood asthma is challenging, and a variety of diagnostic tests for asthma exist. GPs may refer to clinical practice guidelines when deciding which tests, if any, are appropriate, but the quality of these guidelines is unknown. OBJECTIVES: To determine (i) the methodological quality and reporting of paediatric guidelines for the diagnosis of childhood asthma in primary care, and (ii) the strength of evidence supporting diagnostic test recommendations. DESIGN: Meta-epidemiological study of English-language guidelines from the United Kingdom and other high-income countries with comparable primary care systems including diagnostic testing recommendations for childhood asthma in primary care. The AGREE-II tool was used to assess the quality and reporting of the guidelines. The quality of the evidence was assessed using GRADE. RESULTS: Eleven guidelines met the eligibility criteria. The methodology and reporting quality varied across the AGREE II domains (median score 4.5 out of 7, range 2-6). The quality of evidence supporting diagnostic recommendations was generally of very low quality. All guidelines recommended the use of spirometry and reversibility testing for children aged ≥5 years, however, the recommended spirometry thresholds for diagnosis differed across guidelines. There were disagreements in testing recommendations for 3 of the 7 included tests. CONCLUSIONS: The variable quality of guidelines, lack of good quality evidence, and inconsistent recommendations for diagnostic tests may contribute to poor clinician adherence to guidelines and variation in testing for diagnosing childhood asthma.

Patient priority setting in HIV ageing research: exploring the feasibility of community engagement and involvement in Tanzania.

OBJECTIVE: The chronic complications of ageing with HIV are not well studied in sub-Saharan Africa (SSA) where general healthcare resources are limited. We aimed to collaborate with individuals living with HIV aged ≥ 50 years, and community elders (aged ≥ 60 years) living with non-communicable diseases in the Kilimanjaro region of Tanzania in a health research priority-setting exercise. METHODS: We conducted structured workshops based on broad questions to aid discussion and group-based patient priority setting, alongside discussion of the feasibility of future community research engagement. Participant priorities were tallied and ranked to arrive at core priorities from consensus discussion. RESULTS: Thirty older people living with HIV and 30 community elders attended separate priority setting workshops. Both groups reported motivation to participate in, conduct, and oversee future studies. In this resource-limited setting, basic needs such as healthcare access were prioritised much higher than specific HIV-complications or chronic disease. Stigma and social isolation were highly prioritised in those living with HIV. CONCLUSIONS: Community engagement and involvement in HIV and ageing research appears feasible in Tanzania. Ageing and non-communicable disease research should consider the wider context, and lack of basic needs in low-income settings. A greater impact may be achieved with community involvement.

The population in sub-Saharan Africa is ageing. The majority of people living with HIV infection also live in Africa, and they are ageing now that treatment is widely available. Current research on the chronic complications of ageing with and without HIV in sub-Saharan Africa is very limited, meaning that little is known on how to improve symptoms. In this pilot study, researchers from Tanzania and the UK worked with older people living with HIV, and community elders in Tanzania in a health research priority-setting exercise. Thirty older people living with HIV and thirty community elders attended workshops where they listed issues important to them, and then voted for each item as a group. Priorities were ranked in order of importance by adding up the number of votes. We also asked how interested and motivated older people were to work jointly with academic researchers and what might help and support them to do this. Both groups reported that they felt very motivated to participate in, conduct and oversee future research studies. A key finding was that basic needs, such as being able to see a doctor regularly and buying medications, were prioritised much higher than specific HIV-complications or chronic disease. Stigma and social isolation were important issues for older people with HIV. Our pilot findings suggest that meeting basic needs should be a key part of future work on living and ageing with chronic disease in Tanzania. The importance of working with patients and communities is also highlighted.

Effect of Early High-Flow Nasal Oxygen vs Standard Oxygen Therapy on Length of Hospital Stay in Hospitalized Children With Acute Hypoxemic Respiratory Failure: The PARIS-2 Randomized Clinical Trial.

Importance: Nasal high-flow oxygen therapy in infants with bronchiolitis and hypoxia has been shown to reduce the requirement to escalate care. The efficacy of high-flow oxygen therapy in children aged 1 to 4 years with acute hypoxemic respiratory failure without bronchiolitis is unknown. Objective: To determine the effect of early high-flow oxygen therapy vs standard oxygen therapy in children with acute hypoxemic respiratory failure. Design, Setting, and Participants: A multicenter, randomized clinical trial was conducted at 14 metropolitan and tertiary hospitals in Australia and New Zealand, including 1567 children aged 1 to 4 years (randomized between December 18, 2017, and March 18, 2020) requiring hospital admission for acute hypoxemic respiratory failure. The last participant follow-up was completed on March 22, 2020. Interventions: Enrolled children were randomly allocated 1:1 to high-flow oxygen therapy (n = 753) or standard oxygen therapy (n = 764). The type of oxygen therapy could not be masked, but the investigators remained blinded until the outcome data were locked. Main Outcomes and Measures: The primary outcome was length of hospital stay with the hypothesis that high-flow oxygen therapy reduces length of stay. There were 9 secondary outcomes, including length of oxygen therapy and admission to the intensive care unit. Children were analyzed according to their randomization group. Results: Of the 1567 children who were randomized, 1517 (97%) were included in the primary analysis (median age, 1.9 years [IQR, 1.4-3.0 years]; 732 [46.7%] were female) and all children completed the trial. The length of hospital stay was significantly longer in the high-flow oxygen group with a median of 1.77 days (IQR, 1.03-2.80 days) vs 1.50 days (IQR, 0.85-2.44 days) in the standard oxygen group (adjusted hazard ratio, 0.83 [95% CI, 0.75-0.92]; P < .001). Of the 9 prespecified secondary outcomes, 4 showed no significant difference. The median length of oxygen therapy was 1.07 days (IQR, 0.50-2.06 days) in the high-flow oxygen group vs 0.75 days (IQR, 0.35-1.61 days) in the standard oxygen therapy group (adjusted hazard ratio, 0.78 [95% CI, 0.70-0.86]). In the high-flow oxygen group, there were 94 admissions (12.5%) to the intensive care unit compared with 53 admissions (6.9%) in the standard oxygen group (adjusted odds ratio, 1.93 [95% CI, 1.35-2.75]). There was only 1 death and it occurred in the high-flow oxygen group. Conclusions and Relevance: Nasal high-flow oxygen used as the initial primary therapy in children aged 1 to 4 years with acute hypoxemic respiratory failure did not significantly reduce the length of hospital stay compared with standard oxygen therapy.

Mobile phones are hazardous microbial platforms warranting robust public health and biosecurity protocols.

Advancements in technology and communication have revolutionised the twenty-first century with the introduction of mobile phones and smartphones. These phones are known to be platforms harbouring microbes with recent research shedding light on the abundance and broad spectrum of organisms they harbour. Mobile phone use in the community and in professional sectors including health care settings is a potential source of microbial dissemination. To identify the diversity of microbial genetic signature present on mobile phones owned by hospital medical staff. Twenty-six mobile phones of health care staff were swabbed. DNA extraction for downstream next generation sequencing shotgun metagenomic microbial profiling was performed. Survey questionnaires were handed to the staff to collect information on mobile phone usage and users' behaviours. Each of the 26 mobile phones of this study was contaminated with microbes with the detection of antibiotic resistance and virulent factors. Taken together the sum of microbes and genes added together across all 26 mobile phones totalised 11,163 organisms (5714 bacteria, 675 fungi, 93 protists, 228 viruses, 4453 bacteriophages) and 2096 genes coding for antibiotic resistance and virulent factors. The survey of medical staff showed that 46% (12/26) of the participants used their mobile phones in the bathroom. Mobile phones are vectors of microbes and can contribute to microbial dissemination and nosocomial diseases worldwide. As fomites, mobile phones that are not decontaminated may pose serious risks for public health and biosecurity.

Location of end-of-life care of children with cancer: A systematic review of parent experiences.

OBJECTIVE: To synthesize existing qualitative research exploring the experiences of parents caring for children with cancer during the end-of-life phase, and the factors that influence parental decision-making when choosing the location of end-of-life care and death for their child. RESULTS: This review included 15 studies of 460 parents of 333 children and adolescents who died from progressive cancer. Where reported, the majority (58%) of children died at home or in a hospital (39%), with only a small fraction dying in a hospice. Factors impacting decision-making for the location of care included the quality of communication and the quality of care available. Themes related to choosing home for end-of-life care and death included honoring the child's wishes, the familiarity of home, and parents' desire to be their child's primary carer. Preference for the location of death in the hospital included trust in hospital staff, practical logistics, and the safety of the hospital environment.

Effect of Care Coordination Using an Allied Health Liaison Officer for Chronic Noncomplex Medical Conditions in Children: A Multicenter Randomized Clinical Trial.

IMPORTANCE: There is a paucity of high-quality evidence on the effect of care coordination on health-related quality of life among children with chronic noncomplex medical conditions (non-CMCs). OBJECTIVE: To examine whether care coordination delivered by an Allied Health Liaison Officer results in improved quality-of-life (QOL) outcomes for children with chronic non-CMCs and their families. DESIGN, SETTING AND PARTICIPANTS: This multicenter, open label, randomized clinical trial was conducted in pediatric outpatient clinics at 3 Australian hospitals with tertiary- and secondary-level pediatric care facilities. A total of 81 children with chronic non-CMCs and their families participated in the trial for a period of up to 12 months between October 2017 to October 2020. Primary care reviews were offered at 1 week, 3 months, and 6 months after diagnosis. INTERVENTIONS: Eligible children were randomized 1:1 to receive care coordination or standard care. Families of children receiving care coordination were provided access to an Allied Health Liaison Officer, who was responsible for facilitation of health care access across hospital, education, primary care, and community sectors. MAIN OUTCOMES AND MEASURES: The primary outcomes were scores on the Pediatric Quality of Life Inventory (PedsQL), version 4.0, and the PedsQL Family Impact Module, version 2.0, measured at 6 and 12 months. An intent-to-treat approach was used to analyze the data. RESULTS: Of 81 children (mean [SD] age, 8.2 [3.5] years; 55 [67.9%] male), 42 (51.9%) were randomized to care coordination and 39 (48.1%) to standard care. Compared with standard care, care coordination resulted in greater improvements in overall PedsQL scores (difference in score changes between groups, 7.10; 95% CI, 0.44-13.76; P = .04), overall PedsQL Family Impact Module scores (difference in score changes between groups, 8.62; 95% CI, 1.07-16.16; P = .03), and family functioning QOL (difference in score changes between groups, 15.83; 95% CI, 5.05-26.62; P = .004) at 12 months after diagnosis. CONCLUSIONS AND RELEVANCE: In this randomized clinical trial, care coordination improved the quality of life of children with chronic non-CMCs and their families. Further studies should explore specific non-CMCs that may benefit most from care coordination and whether an orientation among health services to provide such a coordination model could lead to longer-term improved clinical outcomes.

Promoting Confident Body, Confident Child in community child health: A mixed-methods implementation study.

OBJECTIVE: To evaluate population-level implementation of Confident Body, Confident Child (CBCC); an evidence-based program providing parenting strategies to promote healthy eating, physical activity and body satisfaction in children aged 2-6 years; with community child health nurses (CHNs). METHODS: This study utilised an implementation-effectiveness hybrid design, with dual focus on assessing: (a) CBCC implementation into Child Health Centres at a regional health service in Queensland, Australia (process evaluation); and (b) CBCC's effect on CHNs' knowledge and attitudes (outcomes evaluation). Process (CBCC reach, dose, fidelity) and outcome data (CHN knowledge of child body image; and attitudes towards higher body weights) were collected during implementation, and pre- and post-intervention delivery to CHNs, respectively. RESULTS: Twenty-six CHNs (all female; mean age 52.7 ± 9.5 years) participated in the study by attending a 1-day CBCC training workshop and completing demographic and outcome surveys. Process evaluation found that CBCC was implemented as planned and reached 56% of CHNs across the health service. Outcome evaluation showed small but non-significant improvements in CHN knowledge (P = .077) and attitudes towards overweight (using Anti-Fat Attitudes scale; significant improvements on willpower sub-scale only (P < .05)). DISCUSSION: This is the first study to evaluate population-wide CBCC implementation in a real-world health service setting with CHNs. Findings highlight the potential for using pragmatic, implementation-focused methodologies to translate preventive eating disorder programs into community child health services.

Streptococcus anginosus group infections in hospitalised children and young people.

AIM: The Streptococcus anginosus group (SAG) comprises three bacterial species colonising the mouth and gastrointestinal and genitourinary tracts and capable of serious pyogenic infections. Although well-described in adults, studies in children are limited. Here, we characterise paediatric SAG infections from a single Australian centre. METHODS: Hospitalised patients aged ≤18 years with positive SAG cultures from January 2009 to December 2019 were identified from Pathology Queensland's Gold Coast Laboratory database and their medical records were reviewed. RESULTS: Two-hundred children (62% male), median age 12 years (interquartile range 6-16), with positive SAG cultures were identified. Overall, 90% received intravenous antibiotics, 89% underwent surgical drainage, 23% were readmitted and 15% required additional surgery. The most common sites were the abdomen (39%), soft tissues (36%) and head and neck regions (21%). Since 2011, Pathology Queensland reported SAG at the species level (n = 133). Of these, S. anginosus was the most prevalent (39%), then S. constellatus (34%) and S. intermedius (27%). Compared with the other two species, S. intermedius was most commonly associated with head and neck infections (relative risk (RR) = 2.2, 95% confidence interval (CI) 1.4-3.5), while S. constellatus (RR = 1.7, 95% CI 1.2-2.4) and S. anginosus (RR = 1.5, 95% CI 1.0-2.0) were each associated with a higher risk of intra-abdominal infection than S. intermedius. Since February 2015, the number of children admitted with SAG-associated intra-abdominal infection per 1000 hospitalisations increased by 29% annually compared with an annual decline of 8% in previous years. CONCLUSIONS: SAG infections occur at various anatomical sites. Despite antibiotics and surgical management, almost one-quarter are re-hospitalised for further treatment.

Ciprofloxacin-associated Peripheral Neuropathy in a Child: A Case Report and Review of the Literature.

Fluoroquinolones are reported to have peripheral nerve toxic effects that can be severe and permanent in adults. However, limited data exist for children. We describe a case of acute-onset peripheral neuropathy associated with ciprofloxacin in a 13-year-old boy who was characterized by severe dysesthesia and erythema of both hands and feet, but which resolved promptly after ceasing the antibiotic.

A Qualitative Study on Formal and Informal Carers' Perceptions of Dementia Care Provision and Management in Malaysia.

Background: The number of people living with dementia worldwide is increasing, particularly in low- and middle-income countries (LMICs) where little is known about existing post-diagnostic care and support. This study aimed to better understand healthcare provision for people living with dementia in Malaysia, and to identify priorities for providing timely, quality, and accessible care and support to all. Methods: This is a qualitative interview study on care providers and facilitators (health and community care professionals, paid carers, traditional medicine practitioners, faith healers, community leaders, non-governmental organisations). A topic guide, piloted in Malaysia and peer reviewed by all LMIC partners, elicited the understanding of dementia and dementia care and barriers and facilitators to care for people living with dementia and carers, and perceptions of key priorities for developing efficient, feasible, and sustainable dementia care pathways. Verbatim transcription of audio-recorded interviews was followed by iterative, thematic data analysis. Results: Twenty interviews were conducted (11 healthcare professionals, 4 traditional medicine practitioners, and 5 social support providers). The findings indicate that dementia care and support services exist in Malaysia, but that they are not fully utilised because of variations in infrastructure and facilities across the country. Despite a locally recognised pathway of care being available in an urban area, people with dementia still present to the healthcare system with advanced disease. The interviewees linked this to a public perception that symptoms of dementia, in particular, are normal sequelae of ageing. Earlier detection of dementia is commonly opportunistic when patients present to GPs, government clinic staff, and general physicians with other ailments. Dementia may only be identified by practitioners who have some specialist interest or expertise in it. Workforce factors that hindered early identification and management of dementia included lack of specialists, overburdened clinics, and limited knowledge of dementia and training in guideline use. Post-diagnostic social care was reported to be largely the domain of families, but additional community-based support was reported to be available in some areas. Raising awareness for both the public and medical professionals, prevention, and more support from the government are seen as key priorities to improve dementia management. Conclusions: This qualitative study provides novel insight into the availability, delivery, and use of post-diagnostic care and support in Malaysia from the perspective of care providers. The respondents in this study perceived that while there was a provision for dementia care in the hospital and community settings, the different care sectors are largely unaware of the services each provides. Future work should explore how care provision across different service sectors and providers can be supported to better facilitate patient access and referral between primary, secondary, and social care. The importance of supporting families to understand dementia and its progression, and strategies to help them care for relatives was emphasised. There is also a need for broad workforce training and development, at both the postgraduate and undergraduate levels, as well as improved general awareness in the community to encourage earlier help-seeking for symptoms of dementia. This will enable the use of preventive strategies and access to specialist services to optimise care and quality of life for people living with dementia in Malaysia.

The role of mobile phones as a possible pathway for pathogen movement, a cross-sectional microbial analysis.

INTRODUCTION: Mobile phones are used the world over, including in healthcare settings. This study aimed to investigate the viable microbial colonisation of mobile phones used by healthcare personnel. METHODS: Swabs collected on the same day from 30 mobile phones belonging to healthcare workers from three separate paediatric wards of an Australian hospital were cultured on five types of agar plate, then colonies from each phone were pooled, extracted and sequenced by shotgun metagenomics. Questionnaires completed by staff whose phones were sampled assisted in the analysis and interpretation of results. RESULTS AND DISCUSSION: All phones sampled cultured viable bacteria. Overall, 399 bacterial operational taxonomic units were identified from 30 phones, with 1432 cumulative hits. Among these were 58 recognised human pathogenic and commensal bacteria (37 Gram-negative, 21 Gram-positive). The total number of virulence factor genes detected was 347, with 1258 cumulative hits. Antibiotic resistance genes (ARGs) were detected on all sampled phones and overall, 133 ARGs were detected with 520 cumulative hits. The most important classes of ARGs detected encoded resistance to beta-lactam, aminoglycoside and macrolide antibiotics and efflux pump mediated resistance mechanisms. CONCLUSION: Mobile phones carry viable bacterial pathogens and may act as fomites by contaminating the hands of their users and indirectly providing a transmission pathway for hospital-acquired infections and dissemination of antibiotic resistance. Further research is needed, but meanwhile adding touching mobile phones to the five moments of hand hygiene is a simple infection control strategy worth considering in hospital and community settings. Additionally, the implementation of practical and effective guidelines to decontaminate mobile phone devices would likely be beneficial to the hospital population and community at large.

Real-time patients' perspectives about participating in teaching consultations in primary care: A questionnaire study.

INTRODUCTION: Patients presenting with undifferentiated illnesses provide valuable learning opportunities for medical students. Evidence detailing the factors that affect patient participation in undergraduate medical education is limited. This study examines how patients regard their participation in teaching consultations in primary care. METHODS: We conducted a cross-sectional questionnaire survey in four GP practices. We tested the relationship between variables of interest and willingness to participate, using hierarchical logistic regression. RESULTS: We analysed 525 questionnaires. 88% of respondents were willing to have students take part in their consultation, and 72% were willing to see a student alone before seeing the doctor. Older patients and those with less sensitive clinical problems were more likely to participate. Willingness to participate was also associated with patients' perceptions of certain costs and benefits of participation. Respondents had poor knowledge about medical education, and a sizeable minority perceived a lack of autonomy about the presence of students in their encounters. More than one-third of respondents expressed the presence of a clinician as a precondition for approval of students' performing some active roles. DISCUSSION: The findings have identified potential interventions to enhance patient involvement including patient education, respecting patient autonomy, and ensuring appropriate student supervision.

Australian Quarantine Policy: From Centralization to Coordination with Mid-Pandemic COVID-19 Shifts.

Combining a historical institutionalism approach with institutional isomorphism and punctuated equilibrium, this article analyzes quarantine policy change across 120 years of Australian quarantine history. By anchoring its analysis within specific time periods (the years before the Spanish flu, seven decades of inaction, and multiple post-1997 pandemic updates and responses), the authors highlight when and why policies did or did not change and how the constant push-and-pull between state and Commonwealth institutional ownership altered policy possibilities. The heart of the analysis showcases how Australia's successful COVID-19 response is a unique output of prior quarantine policies, institutional evolution, and mid-pandemic alterations of key national pandemic response plans.

Multicentre, randomised trial to investigate early nasal high-flow therapy in paediatric acute hypoxaemic respiratory failure: a protocol for a randomised controlled trial-a Paediatric Acute respiratory Intervention Study (PARIS 2).

INTRODUCTION: Acute hypoxaemic respiratory failure (AHRF) in children is the most frequent reason for non-elective hospital admission. During the initial phase, AHRF is a clinical syndrome defined for the purpose of this study by an oxygen requirement and caused by pneumonia, lower respiratory tract infections, asthma or bronchiolitis. Up to 20% of these children with AHRF can rapidly deteriorate requiring non-invasive or invasive ventilation. Nasal high-flow (NHF) therapy has been used by clinicians for oxygen therapy outside intensive care settings to prevent escalation of care. A recent randomised trial in infants with bronchiolitis has shown that NHF therapy reduces the need to escalate therapy. No similar data is available in the older children presenting with AHRF. In this study we aim to investigate in children aged 1 to 4 years presenting with AHRF if early NHF therapy compared with standard-oxygen therapy reduces hospital length of stay and if this is cost-effective compared with standard treatment. METHODS AND ANALYSIS: The study design is an open-labelled randomised multicentre trial comparing early NHF and standard-oxygen therapy and will be stratified by sites and into obstructive and non-obstructive groups. Children aged 1 to 4 years (n=1512) presenting with AHRF to one of the participating emergency departments will be randomly allocated to NHF or standard-oxygen therapy once the eligibility criteria have been met (oxygen requirement with transcutaneous saturation <92%/90% (dependant on hospital standard threshold), diagnosis of AHRF, admission to hospital and tachypnoea ≥35 breaths/min). Children in the standard-oxygen group can receive rescue NHF therapy if escalation is required. The primary outcome is hospital length of stay. Secondary outcomes will include length of oxygen therapy, proportion of intensive care admissions, healthcare resource utilisation and associated costs. Analyses will be conducted on an intention-to-treat basis. ETHICS AND DISSEMINATION: Ethics approval has been obtained in Australia (HREC/15/QRCH/159) and New Zealand (HDEC 17/NTA/135). The trial commenced recruitment in December 2017. The study findings will be submitted for publication in a peer-reviewed journal and presented at relevant conferences. Authorship of all publications will be decided by mutual consensus of the research team. TRIAL REGISTRATION NUMBER: ACTRN12618000210279.

Nasal High Flow in Room Air for Hypoxemic Bronchiolitis Infants.

Background: Bronchiolitis is the most common reason for hospital admission in infants, with one third requiring oxygen therapy due to hypoxemia. It is unknown what proportion of hypoxemic infants with bronchiolitis can be managed with nasal high-flow in room air and their resulting outcomes. Objectives and Settings: To assess the effect of nasal high-flow in room air in a subgroup of infants with bronchiolitis allocated to high-flow therapy in a recent multicenter randomized controlled trial. Patients and Interventions: Infants allocated to the high-flow arm of the trial were initially treated with room air high-flow if saturations were ≥85%. Subsequently, if oxygen saturations did not increase to ≥92%, oxygen was added and FiO2 was titrated to increase the oxygen saturations. In this planned sub-study, infants treated during their entire hospital stay with high-flow room air only were compared to infants receiving either standard-oxygen or high-flow with oxygen. Baseline characteristics, hospital length of stay and length of oxygen therapy were compared. Findings: In the per protocol analysis 64 (10%) of 630 infants commenced on high-flow room air remained in room air only during the entire stay in hospital. These infants on high-flow room air were on average older and presented with moderate hypoxemia at presentation to hospital. Their length of respiratory support and length of stay was also significantly shorter. No pre-enrolment factors could be identified in a multivariable analysis. Conclusions: In a small sub-group of hypoxemic infants with bronchiolitis hypoxemia can be reversed with the application of high-flow in room air only. Trial registration: ACTRN12615001305516.
