Abstract

Objective: The aim of the present study was to describe the epidemiology and clinical features of patients presenting to the ED with suspected and confirmed COVID‐19. Methods: The COVID‐19 ED (COVED) Project is an ongoing prospective cohort study in Australian EDs. This analysis presents data from eight sites across Victoria and Tasmania for July 2020 (during Australia's 'second wave'). All adult patients who met criteria for 'suspected COVID‐19' and underwent testing for SARS‐CoV‐2 in the ED were eligible for inclusion. Study outcomes included a positive SARS‐CoV‐2 test result and mechanical ventilation. Results: In the period 1 July to 31 July 2020, there were 30 378 presentations to the participating EDs and 2917 (9.6%; 95% confidence interval 9.3–9.9) underwent testing for SARS‐CoV‐2. Of these, 50 (2%) patients returned a positive result. Among positive cases, two (4%) received mechanical ventilation during their hospital admission compared to 45 (2%) of the SARS‐CoV‐2 negative patients (odds ratio 1.7, 95% confidence interval 0.4–7.3; P = 0.47). Two (4%) SARS‐CoV‐2 positive patients died in hospital compared to 46 (2%) of the SARS‐CoV‐2 negative patients (odds ratio 1.7, 95% confidence interval 0.4–7.1; P = 0.49). Strong clinical predictors of a positive SARS‐CoV‐2 result included self‐reported fever, non‐smoking status, bilateral infiltrates on chest X‐ray and absence of a leucocytosis on first ED blood tests (P < 0.05). Conclusion: In this prospective multi‐site study from July 2020, a substantial proportion of ED patients required SARS‐CoV‐2 testing, isolation and enhanced infection prevention and control precautions. Presence of SARS‐CoV‐2 on nasopharyngeal swab was not associated with death or mechanical ventilation. [ABSTRACT FROM AUTHOR]

Abstract

Objective The epidemiology of aortic transection is changing with improvements in road safety and the use of endovascular stents. This research investigates the profile of cases and outcomes of traumatic thoracic aortic transection in Victoria, Australia. Methods Data were extracted from the Victorian State Trauma Registry for the period July 2001 to December 2007. Data pertaining to patient demographics, mechanism of injury, method of treatment and mortality were collected. Prehospital mortality for the first year was assessed using National Coroners Information System data. Figures from the Australian Bureau of Statistics were used to establish population incidence rates. Results 69 patients reaching hospital were identified with transection over the study period. A total of 85 cases of transection were identified through coroners9 records. Overall mortality (including prehospital and hospital) was approximately 94.4%. Prehospital mortality was approximately 88.0%. Overall hospital mortality was 33.3%. Patients were predominately men (73.9%) and had a median age of 38 years. Motor vehicle collisions were the most common mechanism (56.5%), with 85.5% of injuries being traffic related. Repair was performed in 46 patients, with 22 receiving initial endovascular repair and 24 receiving initial open repair. Mortality rates following surgery were 9.1% and 16.7%, respectively. Conclusions Aortic transection was generally secondary to traffic-related injury affecting young men, with a mortality rate of over 90%. There has been a trend towards endovascular treatment over open repair in Victorian trauma centres.
