COVID-19 ARDS is a predictable serious complication of COVID-19 that requires early recognition and comprehensive management "This disease is still too strange to us, and there are too many doubts", says Dr Ling Qin (LQ), after reviewing more than 400 patients with coronavirus disease 2019 (COVID-19) pneumonia in Wuhan Union Hospital, China. COVID-19 is a novel disease. We are familiar with acute respiratory distress syndrome (ARDS); however, when it occurs as part of COVID-19, it has different features and there remain unanswered questions. So if someone has COVID-19 ARDS, how does it compare and contrast with ARDS from other causes? To answer this question we provide a summary of the published literature (based on a PubMed search using the terms "COVID-19" and "ARDS", 17 April 2020) and current clinical experience from managing patients with COVID-19 ARDS in Singapore (SHP) and Wuhan (LQ). Severe COVID-19 represents viral pneumonia from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection leading to ARDS. Its manifestations can be viewed as a combination of the…

INTRODUCTION: This statement was planned on 11 March 2020 to provide clinical guidance and aid staff preparation for the coronavirus disease 2019 (COVID-19) pandemic in Australia and New Zealand. It has been widely endorsed by relevant specialty colleges and societies. MAIN RECOMMENDATIONS: Generic guidelines exist for the intubation of different patient groups, as do resources to facilitate airway rescue and transition to the "can't intubate, can't oxygenate" scenario. They should be followed where they do not contradict our specific recommendations for the COVID-19 patient group. Consideration should be given to using a checklist that has been specifically modified for the COVID-19 patient group. Early intubation should be considered to prevent the additional risk to staff of emergency intubation and to avoid prolonged use of high flow nasal oxygen or non-invasive ventilation. Significant institutional preparation is required to optimise staff and patient safety in preparing for the airway management of the COVID-19 patient group. The principles for airway management should be the…

OBJECTIVES: To assess the efficacy of corticosteroid treatment of patients with coronavirus disease 2019 (COVID-19). DESIGN, SETTING: Observational study in the two COVID-19-designated hospitals in Wuhu, Anhui province, China, 24 January - 24 February 2020. PARTICIPANTS: Thirty-one patients infected with the severe acute respiratory coronavirus 2 (SARS-CoV-2) treated at the two designated hospitals. MAIN OUTCOME MEASURES: Virus clearance time, length of hospital stay, and duration of symptoms, by treatment type (including or not including corticosteroid therapy). RESULTS: Eleven of 31 patients with COVID-19 received corticosteroid treatment. Cox proportional hazards regression analysis indicated no association between corticosteroid treatment and virus clearance time (hazard ratio [HR], 1.26; 95% CI, 0.58-2.74), hospital length of stay (HR, 0.77; 95% CI, 0.33-1.78), or duration of symptoms (HR, 0.86; 95% CI, 0.40-1.83). Univariate analysis indicated that virus clearance was slower in two patients with chronic hepatitis B infections (mean difference, 10.6 days; 95% CI, 6.2-15.1…

INTRODUCTION: Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) cause significant morbidity and premature mortality among Australian Aboriginal and Torres Strait Islander peoples. RHDAustralia has produced a fully updated clinical guideline in response to new knowledge gained since the 2012 edition. The guideline aligns with major international ARF and RHD practice guidelines from the American Heart Association and World Heart Federation to ensure best practice. The GRADE system was used to assess the quality and strength of evidence where appropriate. MAIN RECOMMENDATIONS: The 2020 Australian guideline details best practice care for people with or at risk of ARF and RHD. It provides up-to-date guidance on primordial, primary and secondary prevention, diagnosis and management, preconception and perinatal management of women with RHD, culturally safe practice, provision of a trained and supported Aboriginal and Torres Strait Islander workforce, disease burden, RHD screening, control programs and new technologies. CHANGES IN MANAGEMENT AS A RESULT OF THE GUIDELINE: Key…

Weather conditions conducive to extreme bushfires are becoming more frequent as a consequence of climate change.1 Such fires have substantial social, ecological, and economic effects, including the effects on public health associated with smoke, such as premature mortality and exacerbation of cardio-respiratory conditions.2, 3 During the final quarter of 2019 and the first of 2020, bushfires burned in many forested regions of Australia, and smoke affected large numbers of people in New South Wales, Queensland, the Australian Capital Territory and Victoria. The scale and duration of these bushfires was unprecedented in Australia. We undertook a preliminary evaluation of the health burden attributable to air pollution generated by bushfires during this period. Using standard methods for assessing the health impact of air pollution,4 we estimated the numbers of excess deaths, hospitalisations for cardiovascular and respiratory problems, and emergency department presentations with asthma in NSW, Queensland, the ACT and Victoria between 1 October 2019 and 10 February 2020 that could be…

OBJECTIVES: To describe the first isolation and sequencing of SARS-CoV-2 in Australia and rapid sharing of the isolate. SETTING: SARS-CoV-2 was isolated from a 58-year-old man from Wuhan, China who arrived in Melbourne on 19 January 2020 and was admitted to the Monash Medical Centre, Melbourne from the emergency department on 24 January 2020 with fever, cough, and progressive dyspnoea. MAJOR OUTCOMES: Clinical course and laboratory features of the first reported case of COVID-19 (the illness caused by SARS-CoV-2) in Australia; isolation, whole genome sequencing, imaging, and rapid sharing of virus from the patient. RESULTS: A nasopharyngeal swab and sputum collected when the patient presented to hospital were each positive for SARS-CoV-2 (reverse transcription polymerase chain reaction). Inoculation of Vero/hSLAM cells with material from the nasopharyngeal swab led to the isolation of SARS-CoV-2 virus in culture. Electron microscopy of the supernatant confirmed the presence of virus particles with morphology characteristic of viruses of the family Coronaviridae. Whole genome…

OBJECTIVES: To estimate the population prevalence of clinically significant symptoms of depression, generalised anxiety, thoughts of being better off dead, irritability, and high optimism about the future, and of direct experience of COVID-19, loss of employment caused by COVID-19 restrictions, worry about contracting COVID-19, or major disadvantage because of the restrictions; to examine the relationship between these experiences and reporting mental symptoms. DESIGN, SETTING, PARTICIPANTS: Anonymous online survey of adult Australian residents, 3 April - 2 May 2020. MAIN OUTCOME MEASURES: Self-reported psychological status during the preceding fortnight assessed with the Patient Health Questionnaire 9 (PHQ-9; symptoms of depression) and the Generalised Anxiety Disorder Scale (GAD-7). Optimism about the future was assessed with a 10-point study-specific visual analogue scale. RESULTS: 13 829 respondents contributed complete response data. The estimated prevalence of clinically significant symptoms of depression (PHQ-9 ≥ 10) was 27.6% (95% CI, 26.1-29.1%) and of clinically…

Sexual dysfunction is a frequent, potentially distressing, adverse effect of antidepressants and a leading cause of medication non-adherence. Sexual function should be actively assessed at baseline, at regular intervals during treatment, and after treatment cessation. Trials comparing the risk of sexual dysfunction with individual antidepressants are inadequate, but it is reasonable to conclude that the risk is greatest with selective serotonin reuptake inhibitors (SSRIs) and serotonin and noradrenaline reuptake inhibitors (SNRIs), less with tricyclic antidepressants (except clomipramine) and mirtazapine, and least with moclobemide, agomelatine, reboxetine and bupropion. Management of antidepressant-induced sexual dysfunction requires an individualised approach (eg, considering other causes, dose reduction, addition of medication to treat the adverse effect, switching to a different antidepressant). Post-SSRI sexual dysfunction has been recently identified as a potential, although rare, adverse effect of SSRIs and SNRIs. Consider the possibility of post-SSRI sexual dysfunction in…

Objectives To estimate the carbon footprint of five common hospital pathology tests: full blood examination; urea and electrolyte levels; coagulation profile; C-reactive protein concentration; and arterial blood gases. Design, setting Prospective life cycle assessment of five pathology tests in two university-affiliated health services in Melbourne. We included all consumables and associated waste for venepuncture and laboratory analyses, and electricity and water use for laboratory analyses. Main outcome measure Greenhouse gas footprint, measured in carbon dioxide equivalent (CO2e) emissions. Results CO2e emissions for haematology tests were 82 g/test (95% CI, 73–91 g/test) for coagulation profile and 116 g/test (95% CI, 101–135 g/test) for full blood examination. CO2e emissions for biochemical tests were 0.5 g/test CO2e (95% CI, 0.4–0.6 g/test) for C-reactive protein (low because typically ordered with urea and electrolyte assessment), 49 g/test (95% CI, 45–53 g/test) for arterial blood gas assessment, and 99 g/test (95% CI, 84–113 g/test) for urea and electrolyte assessment. Most…

OBJECTIVES: To assess the capacity of intensive care units (ICUs) in Australia to respond to the expected increase in demand associated with COVID-19. DESIGN: Analysis of Australian and New Zealand Intensive Care Society (ANZICS) registry data, supplemented by an ICU surge capability survey and veterinary facilities survey (both March 2020). SETTINGS: All Australian ICUs and veterinary facilities. MAIN OUTCOME MEASURES: Baseline numbers of ICU beds, ventilators, dialysis machines, extracorporeal membrane oxygenation machines, intravenous infusion pumps, and staff (senior medical staff, registered nurses); incremental capability to increase capacity (surge) by increasing ICU bed numbers; ventilator-to-bed ratios; number of ventilators in veterinary facilities. RESULTS: The 191 ICUs in Australia provide 2378 intensive care beds during baseline activity (9.3 ICU beds per 100 000 population). Of the 175 ICUs that responded to the surge survey (with 2228 intensive care beds), a maximal surge would add an additional 4258 intensive care beds (191% increase) and 2631 invasive ventilators…

Compared with the mitigation and suppression approaches of most Western countries, elimination can minimise direct health effects and offer an early return to social and economic activity O n 23 March 2020, New Zealand committed to an elimination strategy in response to the coronavirus disease 2019 (COVID-19) pandemic. Prime Minister Jacinda Ardern announced that on 26 March, NZ would commence an intense lockdown of the country (the highest level of a four-level response framework 1 ). At the time, NZ had just over 100 COVID-19 cases and no deaths, so this "go early, go hard" approach surprised many. However, there were compelling reasons for NZ to pursue elimination. this article we describe why an elimination strategy made sense for NZ, the distinguishing features of this approach, some of the challenges and how they can be overcome, and where we go from here.

INTRODUCTION: A pandemic coronavirus, SARS-CoV-2, causes COVID-19, a potentially life-threatening respiratory disease. Patients with cancer may have compromised immunity due to their malignancy and/or treatment, and may be at elevated risk of severe COVID-19. Community transmission of COVID-19 could overwhelm health care services, compromising delivery of cancer care. This interim consensus guidance provides advice for clinicians managing patients with cancer during the pandemic. MAIN RECOMMENDATIONS: During the COVID-19 pandemic: In patients with cancer with fever and/or respiratory symptoms, consider causes in addition to COVID-19, including other infections and therapy-related pneumonitis. For suspected or confirmed COVID-19, discuss temporary cessation of cancer therapy with a relevant specialist. Provide information on COVID-19 for patients and carers. Adopt measures within cancer centres to reduce risk of nosocomial SARS-CoV-2 acquisition; support population-wide social distancing; reduce demand on acute services; ensure adequate staffing; and provide culturally safe care.…

OBJECTIVES: To investigate the quality of diagnostic and triage advice provided by free website and mobile application symptom checkers (SCs) accessible in Australia. DESIGN: 36 SCs providing medical diagnosis or triage advice were tested with 48 medical condition vignettes (1170 diagnosis vignette tests, 688 triage vignette tests). MAIN OUTCOME MEASURES: Correct diagnosis advice (provided in first, the top three or top ten diagnosis results); correct triage advice (appropriate triage category recommended). RESULTS: The 27 diagnostic SCs listed the correct diagnosis first in 421 of 1170 SC vignette tests (36%; 95% CI, 31-42%), among the top three results in 606 tests (52%; 95% CI, 47-59%), and among the top ten results in 681 tests (58%; 95% CI, 53-65%). SCs using artificial intelligence algorithms listed the correct diagnosis first in 46% of tests (95% CI, 40-57%), compared with 32% (95% CI, 26-38%) for other SCs. The mean rate of first correct results for individual SCs ranged between 12% and 61%. The 19 triage SCs provided correct advice for 338 of 688 vignette tests (49%; 95%…

A rigorous and well supported primary care response to COVID-19 is essential to protect the most vulnerable people in Australia

Engaging First Nations peoples in public health emergencies is critical to reducing health inequities Aboriginal and Torres Strait Islander (respectfully hereafter First Nations) peoples of Australia have experienced poorer health outcomes than the rest of the Australian population during recent pandemics.1, 2 In 2009, during the H1N1 influenza pandemic, diagnosis rates, hospitalisations and intensive care unit admissions occurred at five, eight and three times, respectively, the rates recorded among non-Indigenous people.1-3 The vulnerability of First Nations peoples to coronavirus disease 2019 (COVID-19) is well understood by community leaders and non-Aboriginal policy makers and clinicians alike. The risks for First Nations peoples from COVID-19 taking hold are immense — the oldest continuous culture on the planet is at risk. This is because of all of the following interrelated factors: an already high burden of chronic diseases; longstanding inequity related to service provision and access to health care, especially because 20% of First Nations peoples live in remote and very…

In reply:We thank Triplett and Collett for their interest in our Consensus Statement and for reporting their experience with tracheal intubation in a group of patients with coronavirus disease 2019 (COVID-19).1 They identified hypoxaemia during airway management as a frequent occurrence, and suggest this is exacerbated by the practice of minimising mask ventilation via a bag valve mask following the induction of anaesthesia and avoiding apnoeic oxygenation techniques during tracheal intubation. In the first version of our Consensus Statement (released online as a preprint on 16 March 2020), we advocated that bag valve mask ventilation be used only for rescue oxygenation, in order to minimise the use of a potentially aerosol generating procedure. This recommendation was consistent with guidelines from the United States and the United Kingdom released on 23 and 27 March respectively.2, 3 We became aware, through our own experience and personal correspondence, that profound hypoxaemia was a common occurrence during airway management in COVID-19 patients with respiratory failure. In the…

Misgendering occurs when a person is addressed or described using language that does not match their gender identity.1 Misgendering within the health care system can significantly affect the mental and physical health of transgender (hereafter trans) individuals and can negatively impact future engagement with the health care system. Systemic policies and practices create situations which increase the likelihood of misgendering and experience of stigma, affecting the delivery of health care to trans individuals.

Objective Gut microbiota-produced trimethylamine N-oxide (TMAO) is a risk factor for cardiovascular events. However, conflicting findings regarding the link between plasma TMAO level and prognosis for patients with heart failure have been reported. We examined the association of plasma TMAO concentration with risk of major adverse cardiac events (MACEs) and all-cause mortality in patients with heart failure. Study design Meta-analysis of prospective clinical studies. Data sources We searched electronic databases (PubMed, EMBASE) for published prospective studies examining associations between plasma TMAO level and MACEs and all-cause mortality in adults with heart failure. Data synthesis Hazard ratios (HRs) with 95% confidence intervals for associations between TMAO level and outcomes were estimated in random effects models. In seven eligible studies including a total of 6879 patients (median follow-up, 5.0 years) and adjusted for multiple risk factors, higher plasma TMAO level was associated with greater risks of MACEs (TMAO tertile 3 v tertile 1: HR, 1.68; 95% CI, 1.44–1.96; per…

OBJECTIVES: To describe the characteristics and outcomes of patients with COVID-19 admitted to intensive care units (ICUs) during the initial months of the pandemic in Australia. DESIGN, SETTING: Prospective, observational cohort study in 77 ICUs across Australia. PARTICIPANTS: Patients admitted to participating ICUs with laboratory-confirmed COVID-19 during 27 February - 30 June 2020. MAIN OUTCOME MEASURES: ICU mortality and resource use (ICU length of stay, peak bed occupancy). RESULTS: The median age of the 204 patients with COVID-19 admitted to intensive care was 63.5 years (IQR, 53-72 years); 140 were men (69%). The most frequent comorbid conditions were obesity (40% of patients), diabetes (28%), hypertension treated with angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers (24%), and chronic cardiac disease (20%); 73 patients (36%) reported no comorbidity. The most frequent source of infection was overseas travel (114 patients, 56%). Median peak ICU bed occupancy was 14% (IQR, 9-16%). Invasive ventilation was provided for 119 patients (58%). Median…

OBJECTIVE: To identify individual and organisational factors associated with the prevalence, type and impact of unprofessional behaviours among hospital employees. DESIGN, SETTING, PARTICIPANTS: Staff in seven metropolitan tertiary hospitals operated by one health care provider in three states were surveyed (Dec 2017 - Nov 2018) about their experience of unprofessional behaviours - 21 classified as incivility or bullying and five as extreme unprofessional behaviour (eg, sexual or physical assault) - and their perceived impact on personal wellbeing, teamwork and care quality, as well as about their speaking-up skills. MAIN OUTCOME MEASURES: Frequency of experiencing 26 unprofessional behaviours during the preceding 12 months; factors associated with experiencing unprofessional behaviour and its impact, including self-reported speaking-up skills. RESULTS: Valid surveys (more than 60% of questions answered) were submitted by 5178 of an estimated 15 213 staff members (response rate, 34.0%). 4846 respondents (93.6%; 95% CI, 92.9-94.2%) reported experiencing at least one unprofessional…

Abstract Aims We assessed COVID-19 epidemic risks associated with relaxing a set of physical distancing restrictions in the state of Victoria, Australia – a setting with low community transmission – in line with a national framework that aims to balance sequential policy relaxations with longer-term public health and economic need. Methods An agent-based model, Covasim , was calibrated to the local COVID-19 epidemiological and policy environment. Contact networks were modelled to capture transmission risks in households, schools and workplaces, and a variety of community spaces (e.g. public transport, parks, bars, cafes/restaurants) and activities (e.g. community or professional sports, large events). Policy changes that could prevent or reduce transmission in specific locations (e.g. opening/closing businesses) were modelled in the context of interventions that included testing, contact tracing (including via a smartphone app), and quarantine. Results Policy changes leading to the gathering of large, unstructured groups with unknown individuals (e.g. bars opening, increased public…

The MJA–Lancet Countdown on health and climate change was established in 2017, and produced its first Australian national assessment in 2018 and its first annual update in 2019. It examines indicators across five broad domains: climate change impacts, exposures and vulnerability; adaptation, planning and resilience for health; mitigation actions and health co-benefits; economics and finance; and public and political engagement. In the wake of the unprecedented and catastrophic 2019–20 Australian bushfire season, in this special report we present the 2020 update, with a focus on the relationship between health, climate change and bushfires, highlighting indicators that explore these linkages. In an environment of continuing increases in summer maximum temperatures and heatwave intensity, substantial increases in both fire risk and population exposure to bushfires are having an impact on Australia’s health and economy. As a result of the “Black Summer” bushfires, the monthly airborne particulate matter less than 2.5 μm in diameter (PM2.5) concentrations in New South Wales and the…

OBJECTIVE: To synthesise quantitative data on the effects of rural background and experience in rural areas during medical training on the likelihood of general practitioners practising and remaining in rural areas. STUDY DESIGN: Systematic review and meta-analysis of the effects of rural pipeline factors (rural background; rural clinical and education experience during undergraduate and postgraduate/vocational training) on likelihood of later general practice in rural areas. DATA SOURCES: MEDLINE (Ovid), EMBASE, Informit Health Collection, and ERIC electronic database records published to September 2018; bibliographies of retrieved articles; grey literature. DATA SYNTHESIS: Of 6709 publications identified by our search, 27 observational studies were eligible for inclusion in our systematic review; when appropriate, data were pooled in random effects models for meta-analysis. Study quality, assessed with the Newcastle-Ottawa scale, was very good or good for 24 studies, satisfactory for two, and unsatisfactory for one. Meta-analysis indicated that GPs practising in rural communities…

OBJECTIVES: To assess progress in Australia toward the 2030 WHO hepatitis C elimination targets two years after the introduction of highly effective direct-acting antiviral (DAA) treatments. DESIGN: Analysis of quarterly data on government-subsidised hepatitis C RNA testing and hepatitis C treatment in Australia, January 2013 - June 2018. Changes in testing and treatment levels associated with DAA availability were assessed in an autoregressive integrated moving average (ARIMA) statistical model, and the impact by 2030 of different levels of testing and treatment were estimated using a mathematical model. MAJOR OUTCOME MEASURES: Hepatitis C prevalence among people who inject drugs; annual hepatitis C incidence relative to 2015 levels; projections for the hepatitis C care cascade in 2030. RESULTS: The mean annual number of treatments initiated for people with hepatitis C increased from 6747 during 2013-2015 (before the introduction of DAAs) to 28 022 during 2016-18; the mean annual number of diagnostic RNA tests increased from 17 385 to 23 819. If current trends in testing and…

Children may be more susceptible than originally thought and could play a role in community transmission An early cause for hope in the coronavirus disease 2019 (COVID-19) pandemic was the observation that children are much less likely to experience severe illness than adults.1 This remains true, but has created a perception that children are less susceptible to infection and do not play a substantial role in transmission. In Australia, this perception has been reinforced by assurances from the Prime Minister that schools are safe and that physical distancing is unnecessary in this setting.2 However, emerging research suggests greater caution is needed. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in children is generally characterised by mild illness.1 Only a minority of children require hospitalisation and the case fatality rate is very low (≤ 1%),3, 4 although a small fraction of children can experience a severe post-infectious multisystem inflammatory syndrome.5 Although limited cases in children were reported at the beginning of the pandemic, this may…

INTRODUCTION: Hepatocellular carcinoma (HCC) is a leading cause of cancer deaths both globally and in Australia. Surveillance for HCC in at-risk populations allows diagnosis at an early stage, when potentially curable. However, most Australians diagnosed with HCC die of the cancer or of liver disease. In the changing landscape of HCC management, unique challenges may lead to clinical practice variation. As a result, there is a need to identify best practice management of HCC in an Australian context. This consensus statement has been developed for health professionals involved in the care of adult patients with HCC in Australia. It is applicable to specialists, general medical practitioners, nurses, health coordinators and hospital administrators. METHODS AND RECOMMENDATIONS: This statement has been developed by specialists in hepatology, radiology, surgery, oncology, palliative care, and primary care, including medical practitioners and nurses. The statement addresses four main areas relevant to HCC management: epidemiology and incidence, diagnosis, treatment, and patient…

INTRODUCTION: The coronavirus 2019 disease (COVID-19) pandemic is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Pre-existing cardiovascular disease (CVD) increases the morbidity and mortality of COVID-19, and COVID-19 itself causes serious cardiac sequelae. Strategies to minimise the risk of viral transmission to health care workers and uninfected cardiac patients while prioritising high quality cardiac care are urgently needed. We conducted a rapid literature appraisal and review of key documents identified by the Cardiac Society of Australia and New Zealand Board and Council members, the Australian and New Zealand Society of Cardiac and Thoracic Surgeons, and key cardiology, surgical and public health opinion leaders. MAIN RECOMMENDATIONS: Common acute cardiac manifestations of COVID-19 include left ventricular dysfunction, heart failure, arrhythmias and acute coronary syndromes. The presence of underlying CVD confers a five- to tenfold higher case fatality rate with COVID-19 disease. Special precautions are needed to avoid viral transmission to this…

Chronic fatigue syndrome (CFS) is a prevalent condition affecting about one in 100 patients attending primary care. There is no diagnostic test, validated biomarker, clear pathophysiology or curative treatment. The core symptom of fatigue affects both physical and cognitive activities, and features a prolonged post-activity exacerbation triggered by tasks previously achieved without difficulty. Although several different diagnostic criteria are proposed, for clinical purposes only three elements are required: recognition of the typical fatigue; history and physical examination to exclude other medical or psychiatric conditions which may explain the symptoms; and a restricted set of laboratory investigations. Studies of the underlying pathophysiology clearly implicate a range of different acute infections as a trigger for onset in a significant minority of cases, but no other medical or psychological factor has been reproducibly implicated. There have been numerous small case-control studies seeking to identify the biological basis of the condition. These studies have largely…

The rapid spread of severe acute respiratory syndrome coronavirus 2 led to the declaration of a global pandemic within 3 months of its emergence. The majority of patients presenting with coronavirus disease 2019 (COVID-19) experience a mild illness that can usually be managed in the community. Patients require careful monitoring and early referral to hospital if any signs of clinical deterioration occur. Increased age and the presence of comorbidities are associated with more severe disease and poorer outcomes. Treatment for COVID-19 is currently predominantly supportive care, focused on appropriate management of respiratory dysfunction. Clinical evidence is emerging for some specific therapies (including antiviral and immune-modulating agents). Investigational therapies for COVID-19 should be used in the context of approved randomised controlled trials. Australian clinicians need to be able to recognise, diagnose, manage and appropriately refer patients affected by COVID-19, with thousands of cases likely to present over the coming years.

■The RHD Endgame Strategy: the blueprint to eliminate rheumatic heart disease in Australia by 2031 (the Endgame Strategy) is the blueprint to eliminate rheumatic heart disease (RHD) in Australia by 2031. Aboriginal and Torres Strait Islander people live with one of the highest per capita burdens of RHD in the world. ■The Endgame Strategy synthesises information compiled across the 5-year lifespan of the End Rheumatic Heart Disease Centre of Research Excellence (END RHD CRE). Data and results from priority research projects across several disciplines of research complemented literature reviews, systematic reviews and narrative reviews. Further, the experiences of those working in acute rheumatic fever (ARF) and RHD control and those living with RHD to provide the technical evidence for eliminating RHD in Australia were included. ■The lived experience of RHD is a critical factor in health outcomes. All future strategies to address ARF and RHD must prioritise Aboriginal and Torres Strait Islander people's knowledge, perspectives and experiences and develop co-designed approaches to RHD…

OBJECTIVE: To examine the prevalence of psychotropic medicine dispensing before and after older people enter residential care. DESIGN: Retrospective national cohort study; analysis of Registry of Senior Australians (ROSA) data. SETTING, PARTICIPANTS: All concession card-holding residents of government-subsidised residential aged care facilities in Australia who entered residential care for at least three months between 1 April 2008 and 30 June 2015. MAIN OUTCOME MEASURES: Proportions of residents dispensed antipsychotic, benzodiazepine, or antidepressant medicines during the year preceding and the year after commencing residential care, by quarter. RESULTS: Of 322 120 included aged care residents, 68 483 received at least one antipsychotic (21.3%; 95% CI, 21.1-21.4%), 98 315 at least one benzodiazepine (30.5%; 95% CI, 30.4-30.7%), and 122 224 residents at least one antidepressant (37.9%; 95% CI, 37.8-38.1%) during their first three months of residential care; 31 326 of those dispensed antipsychotics (45.7%), 38 529 of those dispensed benzodiazepines (39.2%), and 25 259 residents…

OBJECTIVES: To prepare more accurate population-based Australian birthweight centile charts by using the most recent population data available and by excluding pre-term deliveries by obstetric intervention of small for gestational age babies. DESIGN: Population-based retrospective observational study. SETTING: Australian Institute of Health and Welfare National Perinatal Data Collection. PARTICIPANTS: All singleton births in Australia of 23-42 completed weeks' gestation and with spontaneous onset of labour, 2004-2013. Births initiated by obstetric intervention were excluded to minimise the influence of decisions to deliver small for gestational age babies before term. MAIN OUTCOME MEASURES: Birthweight centile curves, by gestational age and sex. RESULTS: Gestational age, birthweight, sex, and labour onset data were available for 2 807 051 singleton live births; onset of labour was spontaneous for 1 582 137 births (56.4%). At pre-term gestational ages, the 10th centile was higher than the corresponding centile in previous Australian birthweight charts based upon all births.…

How to deal with diabetes and COVID-19 — do we just dial in? The emergence of severe acute respiratory syndrome coronavirus 2 (SARS�CoV�2), and the subsequent announcement by the World Health Organization of a global pandemic, has altered health care across the public and private sectors. Clearly, coronavirus disease 2019 (COVID-19) is having a huge impact on general practitioners, emergency physicians, respiratory physicians, intensivists and related staff, and is also impacting the day-to-day delivery of chronic health care. Conditions such as type 1 and type 2 diabetes require regular, usually face-to-face contact with GPs, endocrinologists, diabetes educators, dieticians and podiatrists to optimise glycaemic control. However, with recommendations regarding social isolation to minimise spread of COVID-19,1 the delivery of such health care is increasingly being delivered using telehealth. This has been greatly facilitated in Australia with the announcement of temporary Medical Benefits Schedule telehealth (videoconference and telephone) item numbers during the COVID-19 pandemic.2…

To the Editor: Before the coronavirus disease 2019 (COVID-19) pandemic, we had been thinking about how best to re-imagine our university medical program to enhance student experience and learning outcomes. Globally, questions have been raised regarding the utility and format of the pre-clinical content taught in medical programs in the junior years,1 particularly lectures, which have increasingly low attendance rates. There is emerging evidence that blended approaches to education meet the connectivity, flexibility and interactivity expectations of learners,2 and have potential to combine the best of both online and face-to-face teaching. Packaging content in digestible chunks, combined with active learning activities online such as adaptive tutorials, discussions and reflections, results in more meaningful educational experiences for students than didactic lectures.3, 4 The COVID-19 pandemic forced a rapid transition to entirely online teaching for junior medical students. Even components of clinical teaching (other than physical examination) had to proceed in this format. Despite…

All countries must increase medical capabilities and adopt a concerted whole-of-government approach to combat COVID-19 Singapore is a densely populated city-state of 5.7 million and a global travel hub. These characteristics make it particularly susceptible to the importation of communicable diseases and consequent outbreaks. The 2003 severe acute respiratory syndrome (SARS) outbreak challenged the nation's public health system and now the coronavirus disease 2019 (COVID-19) pandemic is presenting a greater challenge. Since December 2019, the virus responsible for COVID-19, SARS-CoV-2, has spread to more than 200 countries and over 4 million cases have been reported.1 Singapore diagnosed its first case on 23 January 2020. In 2003, SARS infected 238 people and killed 33 in Singapore, exposing the weaknesses of the epidemiological surveillance and health care system for emerging infectious diseases.2 Learning from the outbreak, Singapore introduced several key measures to strengthen its pandemic management capabilities. The Disease Outbreak Response System Condition framework was…

OBJECTIVE: To describe uptake of hospital in the home (HIH) by major Australian hospitals and the characteristics of patients and their HIH admissions; to assess change in HIH admission numbers relative to total hospital activity. DESIGN: Descriptive, retrospective study of HIH activity, analysing previously collected census data for all multi-day hospital inpatient admissions to included hospitals during the period 1 January 2011 - 31 December 2017. SETTING, PARTICIPANTS: Nineteen principal referrer hospital members of the Health Roundtable in Australia. MAIN OUTCOME MEASURES: HIH admissions by diagnosis-related group (DRG); patient and admission characteristics. RESULTS: 80 167 of 2 185 421 admissions to the 19 hospitals included HIH care, or 3.7% (95% CI, 3.6-3.7%) of all admissions. Median length of stay for admissions including HIH (7.3 days; IQR, 3.1-14 days) was longer than that for those that did not (2.7 days; IQR, 1.6-5.1 days). For HIH admissions, the proportion of men was higher (54.4% v 45.9%), the proportion of patients who died in hospital was lower (0.3% v 1.4%), and…

To the Editor: Implementation of advice to the public and general practitioners on minimising the risk of COVID-19 exposure and transmission is immensely difficult for people experiencing homelessness and for the health services working with them. Yet this is a population group more vulnerable to infection than most.1 The elevated risk factors for COVID-19 are substantial, as people experiencing homelessness have a much higher prevalence of comorbidity and chronic disease compared with people of the same age who are housed.2 To illustrate further, among the 4000 active patients seen by Homeless Healthcare (Australia's largest specialist homelessness GP practice based in Perth), nearly all patients have comorbidities, 13% have chronic respiratory conditions, 79% smoke (associated with poorer lung health and risk) and 8% have diabetes (associated with supressed immunity). There are parallel calls in Australia and the United Kingdom for clearer government guidance as to how the precautionary measures can be applied in homeless populations. There are a myriad of challenges to this, both…

INTRODUCTION: The incidence of type 2 diabetes mellitus has increased in children and adolescents due largely to the obesity epidemic, particularly in high risk ethnic groups. β-Cell function declines faster and diabetes complications develop earlier in paediatric type 2 diabetes compared with adult-onset type 2 diabetes. There are no consensus guidelines in Australasia for assessment and management of type 2 diabetes in paediatric populations and health professionals have had to refer to adult guidelines. Recent international paediatric guidelines did not address adaptations to care for patients from Indigenous backgrounds. MAIN RECOMMENDATIONS: This guideline provides advice on paediatric type 2 diabetes in relation to screening, diagnosis, diabetes education, monitoring including targets, multicomponent healthy lifestyle, pharmacotherapy, assessment and management of complications and comorbidities, and transition. There is also a dedicated section on considerations of care for children and adolescents from Indigenous background in Australia and New Zealand. CHANGES IN MANAGEMENT…

Psoriasis is a chronic inflammatory disease that is commonly encountered in primary care and is associated with significant morbidity that extends beyond the skin manifestations. Psoriasis is associated with an elevated risk of psoriatic arthritis, cardiovascular disease, obesity, insulin resistance, mental health disorders, certain types of malignancy, inflammatory bowel disease and other immune-related disorders, and hepatic and renal disease. Enhanced recognition of these comorbidities may lead to earlier diagnosis and potentially better overall health outcomes. Psoriatic nail involvement, severe skin disease and obesity are associated with a greater risk of psoriatic arthritis. Individuals with psoriasis should be routinely screened for psoriatic arthritis to allow for early intervention to improve long term prognosis. Life expectancy is reduced in people with psoriasis due to a variety of causes, with cardiovascular disease and malignancy being the most common aetiologies. Psoriasis affects several factors that contribute to worsened quality of life and increased risk of…

It is estimated that about two-thirds of cases of coronavirus disease 2019 (COVID-19) exported from China between 1 and 13 January 2020 were undetected globally. Most of these exported cases were mild and were only detected after several hundred cases had accumulated and severe or fatal cases were recognised 5–8 weeks later, as likely occurred in the COVID-19 outbreaks in Iran, South Korea, Italy and Seattle, United States. The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission globally has been very rapid. The basic reproduction number (R0) is estimated at between 2 and 3. The mode of transmission is thought to be droplet and contact infection, although opportunistic or close range airborne infection may be involved. The transmission dynamics of the early cases of COVID-19 were significantly different to those during the severe acute respiratory syndrome (SARS) epidemic in 2003. In particular, the proportion of COVID-19 cases from health care settings was low and the proportion with no known risk exposures was high. Another significant factor is…

OBJECTIVES: To assess catch-up vaccination of older children and adolescents during the first two years of the "No jab, no pay" policy linking eligibility for federal family assistance payments with childhood vaccination status. DESIGN, SETTING, PARTICIPANTS: Cross-sectional analysis of Australian Immunisation Register data on catch-up vaccination of children aged 5 to less than 7 years before (January 2013 - December 2014; baseline) and during the first two years of "No jab, no pay" (December 2015 - December 2017), and of children aged 7 to less than 10 years and young people aged 10 to less than 20 years ("No jab, no pay" period only). MAIN OUTCOMES: Catch-up vaccination rates for measles-mumps-rubella vaccine second dose (MMR2), by age group, Indigenous status, and socio-economic status; catch-up vaccination of children aged 5 to less than 7 years (third dose of diphtheria-tetanus-pertussis vaccine [DTPa3], MMR1), before and after introduction of "No jab, no pay". RESULTS: The proportion of incompletely vaccinated children aged 5 to less than 7 years who received catch-up DTPa3…

OBJECTIVES: To evaluate the impact of the Victorian Stroke Telemedicine (VST) program during its first 12 months on the quality of care provided to patients presenting with suspected stroke to hospitals in regional Victoria. DESIGN: Historical controlled cohort study comparing outcomes during a 12-month control period with those for the initial 12 months of full implementation of the VST program at each hospital. SETTING: 16 hospitals in regional Victoria that participated in the VST program between 1 January 2010 and 30 January 2016. PARTICIPANTS: Adult patients with suspected stroke presenting to the emergency departments of the participating hospitals. MAIN OUTCOME MEASURES: Indicators for key processes of care, including symptom onset-to-arrival, door-to-first medical review, and door-to-CT times; provision and timeliness of provision of thrombolysis to patients with ischaemic stroke. RESULTS: 2887 patients with suspected stroke presented to participating emergency departments during the control period, 3178 during the intervention period; the patient characteristics were…

OBJECTIVE: To synthesise what is known about women combining motherhood and a career in medicine by examining the published research into their experiences and perspectives. STUDY DESIGN: We reviewed peer-reviewed articles published or available in English reporting original research into motherhood and medicine and published during 2008-2019. Two researchers screened each abstract and independently reviewed full text articles. Study quality was assessed. DATA SOURCES: CINAHL, MEDLINE, PsycINFO, Web of Science, and Scopus abstract databases. DATA SYNTHESIS: The database search identified 4200 articles; after screening and full text assessment, we undertook an integrative review synthesis of the 35 articles that met our inclusion criteria. CONCLUSIONS: Three core themes were identified: Motherhood: the impact of being a doctor on raising children; Medicine: the impact of being a mother on a medical career; and Combining motherhood and medicine: strategies and policies. Several structural and attitudinal barriers to women pursuing both medical careers and motherhood were identified.…

OBJECTIVES: To evaluate whether cannabis use during pregnancy is associated with adverse neonatal outcomes that are independent of cigarette smoking. DESIGN: Prospective cohort study. SETTING: Adelaide (Australia), Auckland (New Zealand), Cork (Ireland), and Leeds, London and Manchester (United Kingdom). PARTICIPANTS: 5610 pregnant nulliparous women with low risk pregnancies recruited for the Screening for Pregnancy Endpoints (SCOPE) study, November 2004 - February 2011. At 14-16 weeks of pregnancy, women were grouped by self-reported cannabis use. MAIN OUTCOME MEASURES: Infant birthweight, head circumference, birth length, gestational age, and severe neonatal morbidity or mortality. RESULTS: 314 women (5.6%) reported using cannabis in the 3 months before or during their pregnancy; 97 (31%) stopped using it before and 157 (50%) during the first 15 weeks of pregnancy, while 60 (19%) were still using cannabis at 15 weeks. Compared with babies of mother who had never used cannabis, infants of those who still used it at 15 weeks had lower mean values for birthweight (adjusted mean…

To the Editor: We write in reference to the recommendations published by Brewster and colleagues1 to report our centre’s experience with tracheal intubation in adults with coronavirus disease 2019 (COVID-19) in Australia. Intubating patients with COVID-19 requires careful balance between providing adequate pre-oxygenation while concurrently maintaining staff safety through minimising aerosolisation. Guidelines from the Safe Airway Society (SAS),1 the Australian and New Zealand Intensive Care Society,2 and overseas3 emphasised rapid sequence induction techniques with the minimisation of bag valve mask ventilation. Our institution developed a specific tracheal intubation protocol for the intubation of patients with suspected or confirmed COVID-19 incorporating the recommendations of the SAS.1 Eight patients with confirmed COVID-19 have been intubated in our intensive care unit. The demographic characteristics of these patients are similar to those reported internationally,4, 5 with a male predominance (seven out of eight) and a mean age of 69 years (range, 52–77 years). Before…
