Establishing a 'Virtual' model of emergency care in Melbourne's southeast.

Digital technologies, specifically those required to facilitate telehealth via an audiovisual medium, are now at a standard that allows them to reliably assess patients with acute complaints within their homes. The coronavirus disease 2019 (COVID-19) pandemic forced innovation and led to an increased acceptance of telehealth from both clinicians and patients and presented an opportunity to incorporate telehealth into emergency medicine practice. With inpatient capacity strain exacerbated by the pandemic, three hospital networks within Melbourne's geographical southeast collaborated with Ambulance Victoria (AV) to set up a virtual emergency department (VED) service in January 2022. This service aimed to allow certain patients to receive care in the more convenient setting of their homes. Referrals were made directly by AV personnel at the home while they were attending to these patients. Consultation with a VED clinician was initiated through a secure audiovisual platform, 'Healthdirect'. Following this consultation, care could be facilitated at home through the VED clinician providing advice regarding treatment that paramedics could administer or through linkage into one of the various outreach services provided by the organisations. The VED represents part of the initial integration of telehealth into our organisations. We hope our initial framework might be built upon through greater integration with community services and incorporating more digital technologies. The ongoing graded expansion of telehealth services within our organisations will likely see more and more patients managed in their own homes.

Modelled economic evaluation of a virtual emergency department in Victoria.

OBJECTIVE: Virtual ED (VED) can potentially alleviate ED overcrowding which has been a public health challenge. The aim of the present study was to conduct a return-on-investment analysis of a VED programme developed in response to changing healthcare needs in Australia. METHODS: An economic model was developed based on initial patient outcome data to assess the healthcare costs, potential costs saved and return on investment (ROI) from the VED. The VED programme operating as part of Alfred Health Emergency Services. The participants were the first 188 patients accessing the Alfred Health VED. VED is the delivery of emergency assessment and management of specific patients virtually via audio-visual teleconferencing. ROI ratios that compare cost savings with intervention costs. RESULTS: The mean total operational cost of VED for 79 days for 188 patients was A$344 117 (95% uncertainty interval [UI] $296 800-$392 088). The VED led to a potential A$286 779 (95% UI $241 688-$330 568) healthcare cost saving from reductions in emergency visits and A$97 569 (95% UI $74 233-$123 117) cost saving in ambulance services. The ROI ratio was estimated at 1.12 (95% UI 0.96-1.32). CONCLUSIONS: The VED was cost neutral in a conservatively modelled scenario but promising if any hospital admission could be saved. Ongoing research examining a larger cohort with community follow up is required to confirm this promising result.

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.

Telehealth consultation before inter-hospital transfer after falls in a subacute hospital (the PREVENT-2 study).

OBJECTIVE: Inter-hospital transfers are increasingly common due to the regionalisation of healthcare, but are associated with patient discomfort, high costs and adverse events. The aim of the present study was to evaluate the effectiveness of a trauma outreach service for preventing inter-hospital transfers to a major trauma centre. METHODS: This was an observational pre- and post-intervention study over a 12-month period from 1 October 2020 to 30 September 2021. Eligible patients sustained a fall at Caulfield Hospital, a subacute care hospital specialising in community services, rehabilitation, geriatric medicine and aged mental health. The intervention was delivery of site-specific education at Caulfield Hospital and a trauma outreach service by specialist trauma clinicians at The Alfred Hospital who provided remote assessment, assisted with clinical management decisions and advised on appropriateness of transfer. RESULTS: The present study included 160 patients in the pre-intervention phase and 203 after the intervention. The primary outcome of transfer occurred in 19 (11.9%) patients in the pre-intervention phase and 4 (2.0%) in the post-intervention phase (P < 0.001). In the subgroup of patients without pelvis or long bone fractures, pre-intervention transfer occurred for 17 (10.9%) patients and post-intervention transfer occurred for 4 (2.0%) patients (P < 0.001). CT imaging was performed for 54 (33.8%) patients in the pre-intervention and 45 (22.2%) patients in the post-intervention group (P = 0.014). CONCLUSIONS: Telehealth consultation with a trauma specialist was associated with significant reduction of inter-hospital transfers, and significant reduction of CT imaging. This supports continuation of the service with scope for expansion and evaluation of patient-centred outcomes.

Emergency department adult presentations from the COVID-19 hotel quarantine program in Victoria, Australia: A retrospective cohort study of admissions and presenting complaints.

OBJECTIVE: The present study aims to describe presentations to the designated ED from the Victorian COVID-19 hotel quarantine program. METHODS: A retrospective cohort study was conducted between 7 December 2020 and 6 June 2021 at The Alfred Emergency and Trauma Centre, a major adult quaternary referral teaching hospital. Participants included adult patients (>18 years old) who were quarantining as part of Victoria's COVID-19 quarantine program. The primary outcome was discharge destination from the ED (admission to hospital vs discharge from ED). RESULTS: Notably, 164 patients presented to The Alfred Emergency and Trauma Centre during the study period. The mean (SD) age was 50.9, with most patients being male (n = 96 [58.5%]). Most patients were referred from a quarantine hotel (n = 83 [50%]). Thirty-four percent (n = 56) of ED presentations were admitted to hospital (31.5% to a ward, 2.5% to intensive care unit). Forty-six percent (n = 75) were discharged to the complex care hotel to be looked after by Alfred Health, with only 16% (n = 26) being discharged to a standard quarantine hotel. The most common presenting complaint categories were: cardiovascular (n = 33 [20%]), miscellaneous (n = 25 [25%]), gastrointestinal (n = 19 [11.5%]) and mental health (n = 18 [11%]). CONCLUSION: The study demonstrates that the number of ED presentations from quarantine was low (<1 presentation/day). COVID Quarantine Victoria and Alfred Health put significant resources into the program to allow most returned international travellers to be safely cared for within a hotel and thus reduce the burden on the public hospital system.

Impact of COVID-19 vaccinations on emergency department presentations.

OBJECTIVE: The aim of the present study was to describe the burden of patients presenting to the ED with symptoms occurring after receiving a COVID-19 vaccination. METHODS: This was a retrospective cohort study performed over a 4-month period across two EDs. Participants were eligible for inclusion if it was documented in the ED triage record that their ED attendance was associated with the receipt of a COVID-19 vaccination. Data regarding the type of vaccine (Comirnaty or ChAdOx1) were subsequently extracted from their electronic medical record. Primary outcome was ED length of stay (LOS) and secondary outcomes included requests for imaging and ED disposition destination. RESULTS: During the study period of 22 February 2021 to 21 June 2021, 632 patients were identified for inclusion in the present study, of which 543 (85.9%) had received the ChAdOx1 vaccination. The highest proportion of COVID-19 vaccine-related attendances occurred in June 2021 and accounted for 21 (8%) of 262 total daily ED attendances. Patients who had an ED presentation related to ChAdOx1 had a longer median ED LOS (253 vs 180 min, P < 0.001) compared to Comirnaty and a higher proportion had haematology tests and imaging requested in the ED. Most patients (n = 588, 88.8%) were discharged home from the ED. CONCLUSION: There was a notable proportion of ED attendances related to recent COVID-19 vaccination administration, many of which were associated with lengthy ED stays and had multiple investigations. In the majority of cases, the patients were able to be discharged home from the ED.
