Massachusetts General Hospital and Brigham and Women’s Hospital are the Boston-based hubs for the Partners TeleStroke Network. The system connects 27 participating hospitals across three states with an escalating chain of access to stroke resources. Spoke hospitals transmit, through a secure link, such clinical data as noncontrast head CT scans to the hub, where a stroke expert “examines” the patient via live video feed and shares in the responsibility for deciding whether to initiate t-PA.
