The drip-and-ship model, which involves referral to the nearest Primary Stroke Center with thrombolysis and subsequent transfer to a Comprehensive Stroke Center, is challenged by the mothership model, which involves direct referral of all patients suspected of LVO to a Comprehensive Stroke Center.
In the study,1 the ability to predict LVO was tested in a large historical cohort of ischemic stroke patients using a mixture of scales developed for LVO, stroke identification, or stroke …
