Outcomes at 3 m in platinum half-hour patients were comparable to later-treated patients and included freedom-from-disability (modified Rankin Scale score, 0–1) in 35.5%, functional independence (modified Rankin Scale score, 0–2) in 53.2%, and mortality in 17.7%. Platinum half-hour acute cerebral ischemia patients did have more severe prehospital motor deficits and younger age platinum half-hour intracranial hemorrhage patients had more severe motor deficits, were more often female, and less often of Hispanic ethnicity. Clinical features among platinum half-hour patients were largely similar to later-treated patients and included age 69 (interquartile range, 57–79), 44.8% women, prehospital Los Angeles Motor Scale median 4 (3–5), and early-postarrival National Institutes of Health Stroke Scale deficit 8 (interquartile range, 3–18). Among platinum half-hour patients, median onset-to-treatment time was 28 minutes (interquartile range, 25–30), and final diagnoses were acute cerebral ischemia in 71.8% (ischemic stroke, 61.5%, TIA 10.3%) intracranial hemorrhage in 26.1% and mimic in 2.5%.
