The interactive electronic information storage and transmission system PRESTEL was assessed as a method of recording and collecting patient record forms from a multicentre trial in anaesthesia. PRESTEL terminals were provided in anaesthetic centres around Britain and all data handled by this public viewdata service, which connects users by telephone to a central computer. The trial was of a new analgesic supplement, alfentanil, and confirmed more rapid recovery of patients as compared with that after traditional anaesthesia with halothane. Advantages of the system were manifold and included reducing the need for the trial monitor to visit the trialist, an electronic "mailbox," confidentiality, and the ability immediately to identify violations of study protocol. No participant found the system too difficult to use, though the small keyboard was a source of complaint. Despite the initial cost of the system its utility vastly outweighs traditional methods of data collection.
交互式电子信息存储与传输系统PRESTEL被评估为一种从麻醉多中心试验中记录和收集患者记录表的方法。PRESTEL终端被安置在英国各地的麻醉中心，所有数据均由这个公共可视数据服务处理，该服务通过电话将用户连接到一台中央计算机。该试验针对一种新型镇痛补充剂阿芬太尼，结果证实与使用氟烷进行传统麻醉相比，患者恢复得更快。该系统的优点众多，包括减少试验监测人员拜访试验人员的需求、一个电子“邮箱”、保密性以及能够立即识别违反研究方案的情况。尽管小键盘引发了一些抱怨，但没有参与者觉得该系统使用起来太难。尽管该系统有初始成本，但其效用大大超过了传统的数据收集方法。
