Emergency clinicians' knowledge, preparedness and experiences of managing COVID-19 during the 2020 global pandemic in Australian healthcare settings.

BACKGROUND: Emergency clinicians have a crucial role during public health emergencies and have been at the frontline during the COVID-19 pandemic. This study examined the knowledge, preparedness and experiences of Australian emergency nurses, emergency physicians and paramedics in managing COVID-19. METHODS: A voluntary cross-sectional study of members of the College of Emergency Nursing Australasia, the Australasian College for Emergency Medicine, and the Australasian College of Paramedicine was conducted using an online survey (June-September 2020). RESULTS: Of the 159 emergency nurses, 110 emergency physicians and 161 paramedics, 67.3-78% from each group indicated that their current knowledge of COVID-19 was 'good to very good'. The most frequently accessed source of COVID-19 information was from state department of health websites. Most of the respondents in each group (77.6-86.4%) received COVID-19 specific training and education, including personal protective equipment (PPE) usage. One-third of paramedics reported that their workload 'had lessened' while 36.4-40% of emergency nurses and physicians stated that their workload had 'considerably increased'. Common concerns raised included disease transmission to family, public complacency, and PPE availability. CONCLUSIONS: Extensive training and education and adequate support helped prepare emergency clinicians to manage COVID-19 patients. Challenges included inconsistent and rapidly changing communications and availability of PPE.

COVID-19 in Australia: our national response to the first cases of SARS-CoV-2 infection during the early biocontainment phase.

BACKGROUND: On 31 December 2019, the World Health Organization recognised clusters of pneumonia-like cases due to a novel coronavirus disease (COVID-19). COVID-19 became a pandemic 71 days later. AIM: To report the clinical and epidemiological features, laboratory data and outcomes of the first group of 11 returned travellers with COVID-19 in Australia. METHODS: This is a retrospective, multi-centre case series. All patients with confirmed COVID-19 infection were admitted to tertiary referral hospitals in New South Wales, Queensland, Victoria and South Australia. RESULTS: The median age of the patient cohort was 42 years (interquartile range (IQR), 24-53 years) with six men and five women. Eight (72.7%) patients had returned from Wuhan, one from Shenzhen, one from Japan and one from Europe. Possible human-to-human transmission from close family contacts in gatherings overseas occurred in two cases. Symptoms on admission were fever, cough and sore throat (n = 9, 81.8%). Co-morbidities included hypertension (n = 3, 27.3%) and hypercholesterolaemia (n = 2, 18.2%). No patients developed severe acute respiratory distress nor required intensive care unit admission or mechanical ventilation. After a median hospital stay of 14.5 days (IQR, 6.75-21), all patients were discharged. CONCLUSIONS: This is a historical record of the first COVID-19 cases in Australia during the early biocontainment phase of the national response. These findings were invaluable for establishing early inpatient and outpatient COVID-19 models of care and informing the management of COVID-19 over time as the outbreak evolved. Future research should extend this Australian case series to examine global epidemiological variation of this novel infection.

Australasian disasters of national significance: an epidemiological analysis, 1900-2012.

BACKGROUND: A regional epidemiological analysis of Australasian disasters in the 20th century to present was undertaken to examine trends in disaster epidemiology; to characterise the impacts on civil society through disaster policy, practice and legislation; and to consider future potential limitations in national disaster resilience. METHODS: A surveillance definition of disaster was developed conforming to the Centre for Research on the Epidemiology of Disasters (CRED) criteria (≥10 deaths, ≥100 affected, or declaration of state emergency or appeal for international assistance). The authors then applied economic and legislative inclusion criteria to identify additional disasters of national significance. RESULTS: The surveillance definition yielded 165 disasters in the period, from which 65 emerged as disasters of national significance. There were 38 natural disasters, 22 technological disasters, three offshore terrorist attacks and two domestic mass shootings. Geographic analysis revealed that states with major population centres experienced the vast majority of disasters of national significance. Timeline analysis revealed an increasing incidence of disasters since the 1980s, which peaked in the period 2005-2009. Recent seasonal bushfires and floods have incurred the highest death toll and economic losses in Australasian history. Reactive hazard-specific legislation emerged after all terrorist acts and after most disasters of national significance. CONCLUSION: Timeline analysis reveals an increasing incidence in natural disasters over the past 15 years, with the most lethal and costly disasters occurring in the past 3 years. Vulnerability to disaster in Australasia appears to be increasing. Reactive legislation is a recurrent feature of Australasian disaster response that suggests legislative shortsightedness and a need for comprehensive all-hazards model legislation in the future.

Blood pressure cuffs as a vector for transmission of multi-resistant organisms: colonisation rates and effects of disinfection.

OBJECTIVE: Blood pressure (BP) cuffs are potential vectors for transmission of multi-resistant organisms (MROs). The present study aims to determine MRO colonisation rates in BP cuffs from areas of high patient flow as an assessment of the quality of disinfection and infection control practices. METHODS: BP cuffs in the ED, high dependency unit (HDU) and operating theatres (OT) were prospectively examined after routine disinfection procedures. Swabs collected from the inner and outer surfaces of BP cuffs during inter-patient intervals were plated onto replicate organism detection and counting, methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) chromogenic agar plates to detect rates of bacterial, MRSA and VRE colonisation, respectively. RESULTS: High bacterial colonisation rates were detected in BP cuffs from all three areas. BP cuffs from OT were significantly less colonised compared with cuffs from HDU and ED; 76% versus 96% and 100% (P < 0.0001) for inner surfaces and 86% versus 98% and 100% (P < 0.0001) for outer surfaces, respectively. Equivalent or higher bacterial growth was observed on the inner surface compared with outer surface in 54%, 84% and 86% of BP cuffs from OT, HDU and ED, respectively. MRSA was detected in 3 of 150 (2%) swabs collected, but no VRE was detected. CONCLUSION: Although MRSA and VRE were infrequently isolated, current disinfection and infection control protocols need to be improved given the greater recovery of organisms from the inner compared with outer surfaces of BP cuffs.

Disaster triage tags: is one better than another?

OBJECTIVE: To determine which of the disaster triage tag systems in use in Australia and New Zealand is better in terms of the time taken to complete the triage and the ease of use. METHODS: A disaster scenario was created. Mock patients were provided with clinical information to allow them to be triaged in a disaster sieve. Six different triage tag systems available in Australia and New Zealand were trialled. Participants triaged 10 patients with each triage tag system. The 10 patients used were different for each of the tag systems and were standardized for acuity and triage category. The time to complete the triage of the 10 patients with each different tag system was measured. The participants then completed a questionnaire with regards to the ease of use of the different tags and were asked to nominate their most preferred tag. RESULTS: The Victorian cruciate fold up tag was the quickest to complete, with an average of 6.6 min to triage 10 patients, compared with an average time for all systems of 7.8 min. New Zealand tags were found to be the easiest to use, easiest to fill in and were considered the most preferred tag. CONCLUSION: The Victorian style of tag was found to be the most efficient in terms of the time to complete a triage. The New Zealand tags were the easiest to use, easiest to fill in and the most preferred tag by the participants. We recommend that one of these tags be adapted for use as a nationwide system.

Brainstem anaesthesia after retrobulbar block: a rare cause of coma presenting to the emergency department.

Local anaesthesia, in particular retrobulbar block, is commonly used to perform cataract surgery. Known complications of retrobulbar block include cranial nerve palsies, seizures and cardiorespiratory arrest. We report a case of brainstem anaesthesia causing apnoea and loss of consciousness in a man who received retrobulbar block. The likely mechanism is inadvertent dural puncture of the optic nerve sheath and local anaesthetic injection into the cerebrospinal fluid space. As in this case, the literature reports a short-lived period of anaesthesia with usually no long-term sequelae. Although rare, it is a life-threatening complication if the patient is not appropriately resuscitated. This case highlights the need for trained personnel, with suitable monitoring and adequate resuscitation facilities in order to perform this technique.
