“We are at the beginning phases of trying to understand our diagnostic accuracy and some other quality measures with regards to teleneurology as well as telestroke. But there is some evidence that we are at least as accurate in the telestroke world at diagnosing things other than stroke. More research needs to be done, but the initial signs are promising.”

 between acute ischemic stroke (AIS) and stroke mimics, with the potential to assess a wider variety of neurological syndromes, according to a recent study presented virtually at the 

2021 American Academy of Neurology (AAN) Annual Meeting

, April 17-22, by Jason Poon, MD, neurologist, University of Utah.

Poon and colleagues conducted a retrospective review of 476 telestroke cases and found a high diagnostic agreement for AIS (88%) with a kappa of 0.75 for stroke and mimics. Telestroke mimic diagnosis had a positive predictive value (PPV) of 85% and a negative predictive value (NPV) of 90%, while telestroke diagnosis of AIS had a PPV of 90% and an NPV of 85%.

spoke with Poon to learn about further research that he would like to conduct with telestroke and teleneurology consultations. He also discussed the potential of teleneurology 

consultations to diagnose a number of conditions.

“From the standpoint of the patient, [telestroke] gives them access to a vascular neurologist in the scenario of stroke consult. But from a management standpoint, it has been shown to improve adherence to stroke protocols, utilization of IV tPA, and more appropriate and quicker referrals to higher centers that allow for mechanical thrombectomy.”

Data from a recent study suggest that telestroke consultations can accurately differentiate between acute ischemic stroke (AIS) and stroke mimics and have the potential to assess a wider variety of neurological syndromes.

These findings were presented virtually at the

spoke with Poon to learn more about the importance of telestroke for patients and medical centers alike. He also spoke about the broader potential of teleneurology to diagnose a variety of neurological syndromes.

The neurologist at University of Utah discussed his research presented at AAN 2021 on telestroke’s accuracy of differentiating between acute ischemic stroke and mimics.
