Disposition of patients utilising the virtual emergency department service in southeast region of Melbourne (SERVED-1).

OBJECTIVE: Supported by the state government, three health networks partnered to initiate a virtual ED (VED), as part of a broader roll-out of emergency telehealth services in Victoria. The aim of the present study (Southeast Region Virtual Emergency Department-1 [SERVED-1]) was to report the initial 5-month experience and included all patients assessed through the service over the first 5 months (1 February 2022 to 30 June 2022). METHODS: VED consults occurred after referral from paramedics in the pre-hospital setting. Electronic medical records were retrospectively reviewed for demographic, presenting complaint and outcome data. The primary outcome was the count of VED consultations. The secondary outcome was the proportion of patients where physical ED attendance was avoided within 72 h. The proportion of physical ED attendances avoided sub-grouped by primary presenting complaints were reported. RESULTS: There were 1748 patients who had a VED consultation, of which 1261 (72.1%; 95% confidence interval [CI] 70.0-74.2) patients had physical presentation to an ED avoided in the 72 h following the consult. There was a significant increase in consultations over the 5-month period (incidence rate ratio 1.27; 95% CI 1.23-1.31, P < 0.001) that was consistent in the three health services. The most common presenting complaints were COVID-19 and shortness of breath, and physical presentation was avoided most often among younger patients and those with COVID-19. CONCLUSIONS: Initial experience demonstrated a significant increase in adoption of the service and an overall avoidance of physical ED attendance by a majority of patients. These results support ongoing VED consultations, complemented by follow up and health economic evaluations.

Evaluating the utility of telehealth in emergency medicine.

There has been great interest regarding tele-emergency care (TEC) and its utility following the COVID-19 pandemic. We have seen a roll out of multiple TEC services across Australia, operating in isolation, without coordination and under differing models of care, creating the potential for an uncoordinated, inefficient healthcare system. We outline a potential framework under which TEC services might function as part of the current system, defining potential strategies that may be used to appropriately coordinate the acute care of select patients outside of the ED as well as improve the efficiency of the physical ED itself.

Outcomes for emergency department patients with suspected and confirmed COVID-19: An analysis of the Australian experience in 2020 (COVED-5).

OBJECTIVE: The aim of the present study was to describe the characteristics and outcomes of patients presenting to Australian EDs with suspected and confirmed COVID-19 during 2020, and to determine the predictors of in-hospital death for SARS-CoV-2 positive patients. METHODS: This analysis from the COVED Project presents data from 12 sites across four Australian states for the period from 1 April to 30 November 2020. All adult patients who met local criteria for suspected COVID-19 and underwent testing for SARS-CoV-2 in the ED were eligible for inclusion. Study outcomes were mechanical ventilation and in-hospital mortality. RESULTS: Among 24 405 eligible ED presentations over the whole study period, 423 tested positive for SARS-CoV-2. During the 'second wave' from 1 July to 30 September 2020, 26 (6%) of 406 SARS-CoV-2 patients received invasive mechanical ventilation, compared to 175 (2%) of the 9024 SARS-CoV-2 negative patients (odds ratio [OR] 3.5; 95% confidence interval [CI] 2.3-5.2, P < 0.001), and 41 (10%) SARS-CoV-2 positive patients died in hospital compared to 312 (3%) SARS-CoV-2 negative patients (OR 3.2; 95% CI 2.2-4.4, P = 0.001). For SARS-CoV-2 positive patients, the strongest independent predictors of hospital death were age (OR 1.1; 95% CI 1.1-1.1, P < 0.001), higher triage category (OR 3.5; 95% CI 1.3-9.4, P = 0.012), obesity (OR 4.2; 95% CI 1.2-14.3, P = 0.024) and receiving immunosuppressive treatment (OR 8.2; 95% CI 1.8-36.7, P = 0.006). CONCLUSIONS: ED patients who tested positive for SARS-CoV-2 had higher odds of mechanical ventilation and death in hospital. The strongest predictors of death were age, a higher triage category, obesity and receiving immunosuppressive treatment.

Epidemiology and clinical features of emergency department patients with suspected COVID-19: Insights from Australia's 'second wave' (COVED-4).

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 during Australia's 'second wave'. METHODS: The COVID-19 ED (COVED) Project is an ongoing prospective cohort study in Australian EDs. This analysis presents data from 12 sites across four Australian states for the period from 1 July to 31 August 2020. All adult patients who met the 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, mechanical ventilation and in-hospital mortality. RESULTS: There were 106 136 presentations to the participating EDs and 12 055 (11.4%; 95% confidence interval [CI] 11.2-11.6) underwent testing for SARS-CoV-2. Of these, 255 (2%) patients returned a positive result. Among positive cases, 13 (5%) received mechanical ventilation during their hospital admission compared to 122 (2%) of the SARS-CoV-2 negative patients (odds ratio 2.7; 95% CI 1.5-4.9, P = 0.001). Nineteen (7%) SARS-CoV-2 positive patients died in hospital compared to 212 (3%) of the SARS-CoV-2 negative patients (odds ratio 2.3; 95% CI 1.4-3.7, P = 0.001). Strong clinical predictors of the SARS-CoV-2 test result included self-reported fever, sore throat, bilateral infiltrates on chest X-ray, and absence of a leucocytosis on first ED blood tests (P < 0.05). CONCLUSIONS: In this prospective multi-site study during Australia's 'second wave', a substantial proportion of ED presentations required SARS-CoV-2 testing and isolation. Presence of SARS-CoV-2 on nasopharyngeal swab was associated with an increase in the odds of death and mechanical ventilation in hospital.
