ObjectiveSuccessful acute stroke intervention depends on early hospitalization. The time interval between stroke onset to hospitalization was examined to identify the factors influencing the interval and also to determine whether treatment time window expansion will translate into more treatment.MethodsData was obtained from Takashima Stroke Registry covering approximately 55,000 residents in Japan. During 1988-2002, the interval between stroke onset and hospitalization was available for 1,446 registered patients (men 761, women 685). Multivariate regression analyses were performed to evaluate the factors influencing early and late admission.ResultsThe proportions of the patients who arrived within 3 h of onset were 61.4%. Only 8.7% of the patients arrived during a 3- to 6-hour interval. A substantial proportion (29.9%) of patients arrived after 6 h. Early stroke hospitalization was significantly associated with the severity of the stroke event and time of stroke onset.ConclusionClinically more severe stroke patients were hospitalized earlier and nocturnal strokes had delayed admission.
