Randomized Controlled Trial Multicenter Study
Outcome in Direct Versus Transfer Patients in the DAWN Controlled Trial.
Background and Purpose- The impact of transfer status on clinical outcomes in the DAWN (DWI or CTP Assessment With Clinical Mismatch in the Triage of Wake-Up and Late Presenting Strokes Undergoing Neurointervention With Trevo) population is unknown. We analyzed workflow and clinical outcome differences between direct versus transfer patients in the DAWN population. Methods- The following time metrics were analyzed for each group: (1) last known well to hospital arrival, (2) hospital arrival to eligibility imaging, (3) hospital arrival to arterial puncture, (4) qualifying imaging to arterial puncture, (5) last known well to arterial puncture, (6) last known well to reperfusion. ⋯ These results may inform prehospital and primary stroke centers triage protocols in patients presenting in the late time window.
