“…This predominance of community acquisition among HCW is a consistent finding in different healthcare settings. 22,23 The significant difference found in our cohort between the RALE score in those with severe versus non-severe disease is in line with previous reports 14 and, together with abnormal pathology investigations, can be utilised to identify a subset of patients with severe disease who require closer follow up.…”

Background: The Northern Sydney Local Health District was one of the first health regions to be affected by COVID-19 in Australia.Aims: To describe the clinical characteristics, risk factors and outcomes in our lowprevalence Australian population.Methods: This is a retrospective analysis of 517 laboratory-confirmed COVID-19 cases between January and June 2020. Patient information was collected as part of routine care within the COVID-19 Virtual Hospital system. Outcomes examined were death, recovery at 30 days and intensive care unit (ICU) admission. Results:The case fatality rate was 1.8%. Multivariate analysis showed factors independently associated with death, composite outcome of death/ICU admission or incomplete recovery at 30 days were age >80 years and presence of two or more comorbidities. Most cases acquired COVID-19 through international (50.9%) or cruise ship travel (9.1%). Healthcare workers comprised 12.8% of the cohort and represented a disproportionately high percentage of the 'unknown' source group (27.6%). The median incubation period was 5 days (interquartile range 3-8); one patient had an incubation period of 15 days. Hospitalisation was required in 11.8%, ICU admission in 2.1% and ventilation in 1.4%. A Radiographic Assessment of Lung Oedema score on chest X-ray of >10 was independently associated with death. Conclusions:In this low prevalence, well resourced Australian setting, we report an overall low mortality. Factors associated with adverse patient outcomes on multivariate analysis were age greater than 80 and the presence of two or more comorbidities. These data can assist in early risk stratification of COVID-19 patients, and in surge capacity planning for hospitals.
