Quantifying Improved Outcomes, Cost Savings, and Hospital Volume Changes From Optimized Emergency Stroke Transport

Daniel A. Paydarfar*, Jessalyn K. Holodinsky, Huda Abbas, Thalia S. Field, Lily W. Zhou, and Noreen Kamal. "Quantifying improved outcomes, cost savings, and hospital volume changes from optimized emergency stroke transport." Stroke. 2022; 53(12), 3644-3651. https://doi.org/10.1161/STROKEAHA.122.039172

Abstract

​

Background: A previously published conditional probability model optimizes prehospital emergency transport protocols for patients with suspected large-vessel occlusion by recommending the transport strategy, drip-and-ship or mothership, that results in a higher probability of an excellent outcome. 

Is improved access to magnetic resonance imaging imperative for optimal ischemic stroke care?

Abstract:

​

Neuroimaging, including CT and MRI, is integral to ischemic stroke (IS) treatment, management, and prevention. However, the use of MRI for IS patients is limited despite its potential to provide high-quality images that yield definitive information related to the management of IS.  MRI is beneficial when the information provided by CT is insufficient for decisions related to the diagnosis, etiology, or treatment of IS.
