ABSTRACT
BACKGROUND: Prehospital delay is a major obstacle for successful treatment of acute stroke. We investigated the annual change of prehospital delay and related factors in patients with acute ischemic stroke (AIS) or transient ischemic attack (TIA). METHODS: From prospective patient registry, demographic and clinical characteristics of patients who presented within 48 hours of symptom onset after AIS or TIA from 2005 to 2008 were analyzed. We compared the annual change of prehospital delay (time from symptom onset to hospital arrival) and the proportion of early arrival (EA-3, prehospital delay<3 h; EA-6, prehospital delay<6 h). We also investigated factors associated with prehospital delay and early arrival. RESULTS: Of 612 patients, 623 events of AIS or TIA were analyzed. The adjusted geometric mean (95% CI) of prehospital delay (hours) was 7.42 (6.07-9.06) in 2005, 8.18 (6.76-9.89) in 2006, 4.39 (3.50-5.51) in 2007, and 4.02 (3.10-5.22) in 2008 (p<0.01). The proportion of early arrival (year) was 23.6% (2005), 31% (2006), 58% (2007), 54% (2008) for EA-3 (p<0.001) and 38.8% (2005), 32.5% (2006), 51.6% (2007), 75% (2008) for EA-6 (p<0.001). Compared with 2006, the adjusted odds (95% CI) for early arrival were 1.54 (0.87-2.71) in 2005, 1.91 (1.11-3.30) in 2007, 2.29 (1.31-4.01) in 2008 for EA-3 and 1.37 (0.84-2.25) in 2005, 1.73 (1.06-2.81) in 2007, 2.03 (1.23-3.36) in 2008 for EA-6. Younger age, severe neurologic deficit, admission through emergency department, cardioembolic stroke, and TIA were also independently associated with early arrival. CONCLUSIONS: From 2005 to 2008, prehospital delay decreased and potential candidates for thrombolytic therapy increased significantly.
