ABSTRACT
INTRODUCTION: Point-of-care ultrasound (POCUS) has been brought to the limelight again, with a surge in lung ultrasound in suspected COVID-19 patients. This is due to POCUS superiority over chest X-ray, equivalent efficacy to computerised tomography chest for COVID-19 diagnosis and potential minimisation of cross-infection. However, inadequate disinfection practices could make ultrasound machines a vector for disease transmission. This study, conducted during the early phase of the COVID-19 pandemic, surveyed the preparedness of Australasian Clinicians for responsible POCUS practice within the Emergency Department (ED). METHODS: An anonymous online survey conducted from 20th April to 3rd June 2020 among emergency clinicians providing POCUS within Australasian EDs investigated preparedness to provide effective POCUS while minimising cross-infection. RESULTS: The survey received 171 responses and 116 being eligible for analysis. Most respondents (n = 96, 98%) had a separate 'hot zone' with a dedicated US device (n = 75, 77%), but lacked COVID-19-specific standard-operating procedures (n = 51, 52%) or a designated safety and compliance officer (n = 36, 37%). Most clinicians (n = 86, 88%) were willing to perform ultrasound in highly infectious patients, despite poor formal training (n = 66, 67%) or COVID-19-specific lung protocols (n = 59, 60%). Most (n = 92, 93%) had access to appropriate low-level disinfectant wipes but varied significantly in disinfection practice due to a lack of timely, formal or unified guidelines. CONCLUSION: Australasian EDs significantly lacked investment in education, training and protocols to conduct safe POCUS in the COVID-19 pandemic. A framework with evidence-based, logistically feasible protocols supporting safe emergency POCUS is required to deal with similar future infectious outbreaks.
