BACKGROUND: The management and outcome of acute ischemic stroke changed dramatically after the introduction of intravenous thrombolysis. However, relatively few patients have received thrombolytic treatment, mainly due to pre-hospital and/or in-hospital delays. Although the causes of these delays have been adequately studied, their change over a long period has not. METHODS: All acute first-ever stroke patients (n = 2,746) presenting to our academic center from 1993 to 2008 were prospectively documented in a computerized stroke data bank. The time from symptoms onset to presentation at the emergency room and to acquisition of a brain CT was calculated. Time trends over this period as well as the factors affecting them were analyzed. RESULTS: The final study cohort consisted of 2,326 acute stroke patients after excluding 302 patients with an unknown time of stroke onset and 118 who suffered a stroke during hospitalization for another illness. Over the 16-year period, the median time from stroke onset to presentation at the emergency room decreased significantly from 3.15 h (interquartile range 1.30-10.30) to 2.00 h (range 1.00-4.00) (p < 0.001). The median time from emergency room presentation to CT scan completion also decreased significantly (p < 0.001) from 12.3 h (range 4.1-29.8) to 1.0 h (range 0.31-2.77). As a result, the proportion of patients having a CT scan within 4 h of stroke onset increased significantly from 8.6% in 1993-1994 to 53.6% in 2007-2008 (p < 0.001). Thrombolytic treatment was applied in 4.15% of all ischemic stroke patients in the period from 2003 to 2008. Along with other significant factors, use of an emergency medical service was associated with a 57% greater chance of presenting within 3 h after symptoms onset. CONCLUSIONS: These results suggest a continued improvement in pre-hospital and in-hospital delays for stroke management. Public awareness and education regarding medical and paramedical services are necessary for the best early management of acute stroke patients.
