Telestroke Expansion
Authors of a study that analyzed the impact of expanding telestroke coverage beyond community ERs credited many postexpansion improvements to the addition of advanced practice providers (APPs). ProMedica Stroke Network, Toledo, Ohio, added seven APPs in June 2020 to provide two-way audiovisual inpatient stroke and TIA consultations and follow-ups at 19 spoke facilities supported by vascular neurologists at the hub comprehensive stroke center (CSC).
Revamping the TS workflow resulted in a threefold increase in TS cart utilization, a 31% decrease in transfers to the CSC, and a higher home discharge rate from spoke hospitals than from the CSC (57.38% versus 52.8%, respectively). Diagnostic sensitivity also improved, with overall decreases in stroke and TIA diagnosis of 11.5% and 39.8%, respectively, and a 12.9% increase in identification of stroke mimics. The study was published in the March Annals of Neurology.
Future Directions
All three author groups called for larger, more granular follow-up studies. Mr. Mohamed said that the 7396-patient review of 33 studies does not show whether video consultations with neurologists produce better outcomes than phone calls, for example, or whether utilizing different telestroke modalities such as a third-party telemedicine service provides better outcomes than other methods. Additionally, authors wrote, future research should compare telestroke versus non-telestroke patient transport models to optimize treatment plans and outcomes and validate potential advantages and disadvantages of telemedicine for patients with acute ischemic stroke.
“There is also a need to understand the long-term outcomes of patients treated via telestroke versus in-person care,” said Dr. Massaud. Future studies could include randomized, controlled trials comparing telestroke to traditional care in various settings with larger sample sizes, he said. “Additionally, research into the cost-effectiveness of telestroke services, patient satisfaction, and the impact of telestroke on different subtypes of stroke could provide a more comprehensive understanding of its benefits and limitations.”
Dr. Massaud and Mr. Mohamed reported no relevant financial interests. Authors of all three studies reported no funding sources or potential conflicts of interest.
