Telestroke Training: Considerations for Expansion of Vascular Neurology Program Requirements.

Telemedicine for stroke (Telestroke) has been a key component to efficient, widespread acute stroke care for many years. The expansion of reimbursement through the Furthering Access to Stroke Telemedicine Act and rapid deployment of telemedicine resources during the COVID-19 public health emergency have further expanded remote care, with practitioners of varying educational backgrounds, and experience providing acute stroke care via telemedicine (Telestroke). Some Telestroke practitioners have not had fellowship-level vascular neurology training and many are without training specific to virtual modalities. While many vascular neurology fellowship programs incorporate Telestroke training into the curriculum, components of this curriculum are not consistent, extent of involvement is variable, and not all fellows receive hands-on training in remote care. Furthermore, the extent of training and evaluation of Telestroke in American Board of Psychiatry and Neurology training requirements and Accreditation Council for Graduate Medical Education assessments for vascular neurology fellowship are not standardized. We suggest that Telestroke be formally incorporated into vascular neurology fellowship curricula and provide considerations for key components of this training and metrics for evaluation.

Visual review of acute stroke neuroimaging prior to transfer acceptance increases likelihood of endovascular therapy.

OBJECTIVES: Demand for thrombectomy, and interhospital transfer to comprehensive stroke centers (CSCs), for acute stroke is increasing. There is an urgent need to identify patients most likely to benefit from transfer. We evaluated whether CSC providers' review of neuroimaging prior to transfer acceptance improved patient selection for thrombectomy and correlated with higher rates of treatment. MATERIALS AND METHODS: A retrospective database of all patients transferred to Stanford's CSC for thrombectomy between 2015-2019 was used. Pre-acceptance images, when available for visual review, were reviewed by the CSC stroke team via virtual PACS, RAPID software, or LifeImage platforms. RESULTS: 525 patients met inclusion criteria. 147 (28%) had neuroimaging available for review prior to transfer. Of those who did not recanalize en route, 267 (50.8%) underwent thrombectomy. Patients with imaging available for review prior to acceptance were significantly more likely to receive thrombectomy (68% vs 54%, RR 1.26; p=0.006, 95% CI 1.09-1.48). Patient images that were reviewed via RAPID were CT-based perfusion studies; these were more likely to receive thrombectomy (70% vs 54%, RR 1.30; p=0.01, 1.09-1.56). Patients who received EVT were more likely to have had pre-transfer vessel imaging, regardless of availability for visual review (76% vs 59%, RR 1.44; p<0.001, 1.18-1.76). CONCLUSIONS: Patients with concern for acute stroke transferred for consideration of thrombectomy who had neuroimaging visually reviewed prior to transfer acceptance and did not recanalize by time of arrival were significantly more likely to undergo thrombectomy. Additional prospective studies are needed to confirm our findings.
