A simple clinical score (ABCD(2) score) has been introduced to triage TIA patients with a high early risk of stroke. External validation studies have yielded inconsistent results regarding the predictive ability of the ABCD(2) score. We aimed to prospectively validate the former score in a multicenter case series study. ⋯ Our findings externally validate the usefulness of the ABCD(2) score in triaging TIA patients with a high risk of early stroke in a multiethnic sample of hospitalized patients. The present data support current guidelines endorsing the immediate hospitalization of patients with an ABCD(2) score >2.
