An exploratory study investigating the barriers, facilitators, and demands affecting caregivers in a telemedicine integrated ambulance-based setting for stroke care.
This study investigates the impact of telemedicine on workload, teamwork, workflow, and communication of geographically distributed caregivers delivering stroke care in ambulance-based telemedicine. Simulated stroke sessions were conducted with selected caregivers, then followed with a survey and interviews. Findings showed that barriers included frustration with equipment, the loss of personal connection of the neurologists with the patients, and physical constraints in the ambulance. Facilitators included live visual communication increasing teamwork and efficiency, the ease of access to neurologist, increased flexibility, and high overall satisfaction and usability.

Prehospital comprehensive stroke center vs primary stroke center triage in patients with suspected large vessel occlusion stroke.
This study’s objective was to evaluate the association of a regional prehospital transport policy that directly triages patients with suspected large vascular occlusion (LVO) stroke to the nearest comprehensive stroke center with rates of endovascular therapy (EVT). This retrospective, multicenter preimplementation-postimplementation study used an interrupted time series analysis to compare treatment rates before and after implementation in patients with acute ischemic stroke (AIS) arriving at 15 primary stroke centers and 8 comprehensive stroke centers in Chicago, Illinois, via emergency medical services (EMS) transport from December 1, 2017, to May 31, 2019. Among 7709 individuals with stroke, 663 with AIS arrived within 6 hours of stroke onset by EMS transport. The EVT rate increased overall among patients with AIS postimplementation and among EMS-transported patients with AIS within 6 hours of onset. There were no differences in EVT rates in patients not arriving by EMS within the 6- to 24-hour window or by interhospital transfer or walk-in.

Improving prehospital stroke diagnosis using natural language processing of paramedic reports.
Accurate prehospital diagnosis of stroke by emergency medical services (EMS) can increase treatments rates, mitigate disability, and reduce stroke deaths. IN this study, the investigators aimed to develop a model that utilized natural language processing of EMS reports and machine learning to improve prehospital stroke identification. The investigators conducted a retrospective study of patients transported by the Chicago EMS to 17 regional primary and comprehensive stroke centers.
