Telemedicine on Par with On-Site Neurologists for Stroke Evaluation: Landmark Study
A groundbreaking study presented at the European Stroke Conference (ESO) reveals that evaluating potential stroke patients via telemedicine in ambulances is as effective as having a neurologist physically present.The research suggests that remote neurological assessments may even save time overall.
The Rise of Mobile Neurovascular Units
For years, medical professionals have recognized the importance of rapid response in stroke cases. Mobile neurovascular units (MNUs), specialized ambulances equipped with scanners and staffed by trained healthcare providers, have emerged as a promising solution. Now, telemedicine is further enhancing these capabilities.
Did you know? Stroke is a leading cause of long-term disability in the United States. Rapid diagnosis and treatment are crucial to minimizing brain damage.
Dr. Vignan Yogendrakumar, from the University of Ottawa, and his research team explored the potential of telemedicine in stroke assessment. Their study protocol, published in the Journal of the American Heart Association (JAHA), highlights the benefits of remote neurological evaluations by specialists.
Study design: Telemedicine vs. Traditional Approach
The clinical trial compared two models of stroke care:
- Telemedicine Model: Neurological assessment conducted remotely by a specialist.
- Traditional Model: Assessment performed in the ambulance by a specialized nurse, a neurologist, and two paramedics.
A total of 275 patients were randomly assigned to either the telemedicine or traditional MNU approach, depending on neurologist availability. The study, conducted as an open-label trial, focused on a composite primary outcome that measured:
- Safety: Ensuring patient well-being during the evaluation process.
- Time to Therapeutic Decision-Making: How quickly treatment decisions were made.
- Resource Utilization: Efficient use of neurologist time and resources.
Key Findings: Telemedicine Proves Effective
The analysis of the composite outcome favored telemedicine in 76% of patients, while the traditional on-board neurological evaluation was preferred in 21% of cases. In the remaining 4%, there was no significant difference between the two approaches.
Specifically, neurological evaluation via telemedicine was associated with a significantly greater probability of favorable outcomes, boasting an odds ratio statistically significant of 3.5
compared to on-board evaluation.
Adverse event rates were similar in both groups, with 13% for telemedicine and 12% for on-board evaluation.
Pro Tip: Telemedicine can be notably valuable in rural areas or regions with limited access to neurologists, ensuring timely stroke assessments nonetheless of location.
Time Efficiency and Resource Allocation
While the median decision-making time was slightly longer with telemedicine (19 minutes vs. 13 minutes), neurologists using telemedicine dedicated 100% of their time to patient assessment, compared to approximately one-third of their time when physically present in the ambulance.
Ultimately, about 18% of patients in both groups received thrombolysis or were transferred to a neuroradiology center for thrombectomy. Functional outcomes at three months were comparable between the telemedicine and on-board evaluation groups.

It has long been supposed that the reference model for the mobile UNV is to have the physically on -board neurologist.But our results show that telemedicine is also effective and provides comparable results in key operational fields.Dr. Vignan Yogendrakumar,University of Ottawa
Future Directions
The researchers concluded that this study paves the way for further investigations to determine the feasibility,cost-effectiveness,and optimal implementation strategies for telemedicine in mobile stroke units.
