We compared the INR (International Normalized Ratio) monitoring process using a telemedicine device with the conventional approach in which blood samples were sent to the hospital for analysis. We conducted a randomized controlled trial. We enrolled 40 patients on chronic warfarin therapy from two primary healthcare centres (PHCs). Half were monitored using the telemedicine device and half were monitored conventionally. Each patient received three INR measurements. The total processing time was measured from blood sampling until warfarin dosing was performed in the anticoagulant clinic. The median total processing time was significantly shorter with telemedicine than usual care (34 vs. 260 min, P < 0.001). This was mainly because sample transport was avoided using the point-of-care device and automatic data transmission. Telemedicine reduced the total processing time for INR monitoring and has the potential to improve the management of patients undergoing anticoagulant treatment at PHCs.
我们比较了使用远程医疗设备进行 INR（国际标准化比值）监测的过程与传统方法，后者需要将血样送往医院进行分析。我们进行了一项随机对照试验。我们从两个初级保健中心（PHC）招募了 40 名正在接受慢性华法林治疗的患者。一半患者使用远程医疗设备进行监测，另一半患者采用常规方法监测。每位患者接受了三次 INR 测量。从采血到在抗凝诊所进行华法林给药的总处理时间进行了测量。使用远程医疗的总处理时间明显短于常规护理（34 分钟与 260 分钟，P < 0.001）。这主要是因为使用即时检测设备和自动数据传输避免了样本运输。远程医疗缩短了 INR 监测的总处理时间，有可能改善在 PHC 接受抗凝治疗的患者的管理。
