Abstract
1 A hospital-based drug information system has been used to assess the time for which patients treated with warfarin were outside the range of Thrombotest values 5-10% and 5-15% and to examine possible contributory factors in situations where anticoagulation fell outside these ranges. 2 Anticoagulant control varied with the age of the patient and with concomitant drug therapy but not with patient sex or indication of anticoagulation. 3 Most patients were 'under-anticoagulated' at some stage but patients over 70 years spent significantly longer in the 5-10% range than those in the age range 30-59 years and Thrombotest values of less than 5% were found predominantly in the older group. 4 Patients given drugs known to interact with warfarin spent least time in the defined Thrombotest ranges. Those on drugs known to potentiate warfarin effect had significantly lower Thrombotest values than the other patients studied.
摘要
- 一个基于医院的药物信息系统已被用于评估接受华法林治疗的患者超出凝血酶检测值5 - 10%和5 - 15%范围的时间，并检查抗凝作用超出这些范围时可能的促成因素。2. 抗凝控制随患者年龄和伴随药物治疗而变化，但不随患者性别或抗凝指征而变化。3. 大多数患者在某些阶段处于“抗凝不足”状态，但70岁以上的患者在5 - 10%范围内花费的时间明显长于30 - 59岁年龄组的患者，且凝血酶检测值低于5%的情况主要出现在老年组。4. 服用已知与华法林相互作用药物的患者在规定的凝血酶检测范围内花费的时间最少。服用已知增强华法林作用药物的患者的凝血酶检测值明显低于其他研究患者。
