NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Optimizing Rural Stroke Care: Video-Conferencing Teleconsultation Improves Transfer Efficiency and Functional Outcome
ABSTRACT
Background:
Acute ischemic stroke (AIS) management in rural regions is challenged by interhospital transfer delays, impacting outcomes.
Objective:
This study evaluates the efficacy of video-conferencing teleconsultation on improving transfer efficiency and clinical outcomes in a hub-and-spoke model.
Methods:
This retrospective cohort study (January 2022–December 2024) included AIS patients identified as potential EVT candidates, transferred from a primary stroke center (PSC) to a comprehensive stroke center (CSC). Patients were categorized into teleconsultation and standard referral process (SRP) groups. The primary outcome was door-in-door-out (DIDO) time, with additional analyses on its components. Secondary outcomes included stroke-related decision-making and 90-day functional outcome using modified Rankin Scale (mRS). Safety outcomes included all-cause mortality within 90 days and symptomatic intracranial hemorrhage after intravenous thrombolysis and/or EVT.
Results:
A total of 83 patients were included, with 41 in the teleconsultation group and 42 in the SRP group (mean age: 73.3 years), and baseline characteristics were comparable. Teleconsultation significantly reduced DIDO time (95.2±22.9 vs. 132.3±41.5 minutes, p<0.001) by shortening CTA-to-ambulance notification time (44.6±17.4 vs. 79.5±37.6 minutes, p<0.001). Teleconsultation group had higher intravenous thrombolysis rates at the PSC (63.4% vs. 40.5%, p=0.04), higher EVT rates (34.2% vs. 14.3%, p=0.035) and shorter door-to-puncture time (83.0±35.5 vs. 118.5±25.9 minutes, p=0.04) at the CSC, with a significant shift toward better mRS at 90th day (OR: 4.55, p<0.001 vs. OR: 1.35, p=0.07). Safety outcomes were comparable between groups.
Conclusions:
Video-conferencing teleconsultation improves interhospital transfer efficiency, stroke-related decision-making, and functional outcomes. This study highlights its potential in optimizing rural stroke care.
