Outcomes of a state-wide virtual emergency department in Victoria, Australia: a linked data analysis of emergency department utilisation and hospital use.
Article in The Lancet regional health. Western Pacific, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The Victorian Virtual Emergency Department (VVED) is a synchronous video-based emergency care service established to reduce the burden on physical EDs by managing patients remotely. Despite rapid growth in virtual emergency care models, evidence regarding downstream hospital utilisation and factors associated with subsequent ED presentation remains limited. We aimed to examine downstream ED utilisation following a VVED consultation and identify factors associated with unplanned ED presentation. Methods: We conducted a retrospective cohort study using linked statewide administrative data. The study included all patients registered with the VVED between 1 July 2022 and 23 June 2023. The primary outcome was unplanned ED presentation within 48 h among patients initially managed in the community. Secondary outcomes included discharge destination and planned and unplanned ED utilisation within 48 h and 7 days. Mixed-effects logistic regression was used to identify factors associated with unplanned ED presentation. Findings: Of 100,422 VVED presentations, 75.5% (n = 75,871) were managed at home and 15.3% (n = 15,353) were referred to a physical ED. Among patients managed at home, 8.2% (n = 6202) attended a physical ED within 48 h, increasing to 11.4% (n = 8667) within 7 days. Overall, 81.5% (n = 81,840) of patients did not attend a physical ED within 48 h. Primary diagnosis category was the only factor independently associated with unplanned ED presentation within 48 h. Interpretation: Most patients were managed in the community, with low unplanned ED utilisation. Higher unplanned rates in our Healthcare Professional pathway likely reflect greater clinical complexity. Further research is needed to explore long-term outcomes, patient perspectives, optimal referral pathways for high-risk groups and the temporal and causal relationship between VVED implementation and physical ED utilisation. Funding: This study was conducted as part of a Digital Health Cooperative Research Centre project, a partnership between La Trobe University, Northern Health, and the Victorian Department of Health.
