Intravenous tissue plasminogen activator (tPA) within 3 hours of stroke onset is a licensed proven therapy for ischaemic stroke, with recent trial data showing benefit up to 4.5 hours. We previously published in this journal data of a survey conducted in 2004 showing only 9% of ischaemic stroke patients presenting to the Singapore General Hospital (SGH) arrived within 2 hours of onset. We aimed to determine whether the problem of delayed hospital arrival persists in 2009 and to establish the impact of widening the time window for intravenous tPA to 4.5 hours.
We prospectively surveyed consecutive ischaemic stroke patients admitted to the SGH from 9th March to 30th April 2009. Patients and/or relatives were interviewed with a standardised form similar to the 2004 survey.
Among the 146 ischaemic stroke patients surveyed (median age 67 years, 59% male, median NIHSS score 2), 6% presented to SGH within 2 hours and 15% within 3.5 hours of onset. Median time from stroke onset to hospital arrival was 1245 minutes (20.75 hours). Pre-hospital consultation was significantly associated with hospital arrival after 2 hours from onset. Main reasons cited for delay were not realising the gravity of symptoms (31%) and not recognising them as stroke (27%).
Delayed arrival to SGH following acute ischaemic stroke remains a problem in 2009. This confirms the lack of stroke awareness in Singapore and highlights the need for public stroke education. Furthermore, these data confirm that widening the time window for intravenous tPA treatment to 4.5 hours at SGH will increase its utilisation.
静脉注射组织型纤溶酶原激活剂(tPA)在卒中发病后 3 小时内是一种经许可证实有效的缺血性卒中治疗方法,最近的试验数据显示获益时间可延长至 4.5 小时。我们之前在本刊发表了一项 2004 年的调查数据,显示仅有 9%的缺血性卒中患者在发病后 2 小时内到达新加坡中央医院(SGH)。我们旨在确定在 2009 年,卒中患者延迟到院的问题是否仍然存在,并确定将静脉 tPA 时间窗扩大至 4.5 小时的影响。
我们前瞻性地调查了 2009 年 3 月 9 日至 4 月 30 日期间连续入住 SGH 的缺血性卒中患者。采用类似于 2004 年调查的标准表格对患者和/或家属进行访谈。
在调查的 146 例缺血性卒中患者中(中位年龄 67 岁,59%为男性,中位 NIHSS 评分为 2 分),6%的患者在发病后 2 小时内、15%的患者在 3.5 小时内到达 SGH。从卒中发病到到达医院的中位时间为 1245 分钟(20.75 小时)。发病后 2 小时到达医院与发病前接受过咨询有显著相关性。延迟的主要原因是没有意识到症状的严重性(31%)和没有意识到是卒中(27%)。
2009 年,急性缺血性卒中后患者延迟到达 SGH 仍是一个问题。这证实了新加坡对卒中的认识不足,并强调了需要进行公众卒中教育。此外,这些数据证实将 SGH 内静脉 tPA 治疗的时间窗扩大至 4.5 小时将增加其利用率。
