The aim of this study was to estimate and explore the incidence of warfarin-related bleeding in a representative sample of patients in the United Kingdom. We identified 3958 patients aged 40 to 84 years, newly treated with warfarin and with no prior history of bleeding from the General Practice Research Database, and followed them for 12 months. The overall incidence of first-time, idiopathic bleeding was 15.2 per 100 patient-years of current warfarin exposure: the incidence of fatal/hospitalised and referred bleeding was 3.5 and 2.6 per 100 patient-years, respectively.
本研究的目的是估计并探究在英国具有代表性的患者样本中与华法林相关的出血发生率。我们从全科医疗研究数据库中识别出3958名年龄在40至84岁之间、新接受华法林治疗且既往无出血史的患者,并对他们进行了12个月的随访。首次特发性出血的总体发生率为每100患者-年当前华法林暴露量中有15.2例:致命/住院及转诊出血的发生率分别为每100患者-年3.5例和2.6例。
