Recombinant factor VIIa (rFVIIa) is used in patients with hemophilia who had developed inhibitors. A hemostatic effect has been demonstrated following the administration of rFVIIa in patients after trauma and bleeding. Currently, there is no widely accepted guideline for off-label rFVIIa usage in bleeding patients. We planned to review the rFVIIa utilization practice in our institution and develop policies and guidelines for future rFVIIa use. We acquired the medical records of 55 patients who received rFVIIa at our institution during 2003-2004. Patient charts were reviewed regarding their rFVIIa administration and indications, dose and frequency, cost, pre-rFVIIa blood component usage, utilization of hematology services and outcome were analyzed. Underlying liver disease with coagulopathy was the commonest (47%) indication for rFVIIa use. Recombinant FVIIa was successful (69%) in correcting laboratory parameters of coagulopathy, but did not alter outcome. Twenty-six of the 55 patients (47%) died during the same admission from their underlying diseases. Apart from two trauma patients, no one died from bleeding. We conclude that unregulated continuous administration of rFVIIa in bleeding/coagulopathic patients did not alter outcome. Closer monitoring of rFVIIa usage, including hematology consultation and enforcement of pre-rFVIIa blood component usage would optimize cost-effectiveness.
重组凝血因子VIIa(rFVIIa)用于已产生抑制剂的血友病患者。在创伤和出血后的患者中给予rFVIIa后已证实有止血作用。目前,对于出血患者中rFVIIa的超说明书使用尚无广泛接受的指南。我们计划回顾我院rFVIIa的使用情况,并制定未来rFVIIa使用的政策和指南。我们获取了2003年至2004年期间在我院接受rFVIIa治疗的55例患者的病历。回顾患者病历,分析其rFVIIa的给药情况、适应证、剂量和频率、费用、rFVIIa使用前血液成分的使用情况、血液学服务的利用情况及结局。合并凝血病的潜在肝病是rFVIIa使用最常见的适应证(47%)。重组凝血因子VIIa成功纠正凝血病实验室指标的比例为69%,但未改变结局。55例患者中有26例(47%)在同一次住院期间死于基础疾病。除2例创伤患者外,无人死于出血。我们得出结论,在出血/凝血病患者中无规范地持续使用rFVIIa并未改变结局。加强对rFVIIa使用的监测,包括血液学会诊及rFVIIa使用前血液成分使用的管理,将优化成本效益。
