Telemedicine vascular neurologist assessment on mobile stroke units is reliable and accurate. This supports its use alongside onboard neurologists for faster stroke treatment decisions.
Area of Science:
- Neurology
- Emergency Medicine
- Telehealth
Background:
- The Benefits of Stroke Treatment Delivered Using a Mobile Stroke Unit (BEST-MSU) study is a comparative effectiveness trial.
- A substudy evaluated interrater agreement for tissue-type plasminogen activator eligibility between telemedicine and onboard vascular neurologists.
Purpose of the Study:
- To assess the reliability and accuracy of telemedicine vascular neurologist assessments in a mobile stroke unit setting.
- To compare the diagnostic agreement between telemedicine and onboard vascular neurologists for stroke treatment decisions.
Main Methods:
- Independent evaluations by telemedicine and onboard vascular neurologists were conducted on scene.
- Key data points included tissue-type plasminogen activator decisions, National Institutes of Health Stroke Scale scores, and CT interpretations.
- Agreement was quantified using Cohen κ statistic, with technical failures recorded.
Main Results:
- Telemedicine vascular neurologist assessment was attempted in 174 patients.
- Technical failures prevented assessment in 2% of cases (4 patients).
- High agreement (88%, κ=0.73) was observed between telemedicine and onboard vascular neurologist evaluations.
Conclusions:
- Remote telemedicine vascular neurologist assessment is reliable and accurate.
- This validates the use of telemedicine neurologists as a viable option on mobile stroke units.
- Findings support the integration of telemedicine for enhanced stroke care delivery.
