To evaluate interactive computer-based informed consent for use of contrast material versus the same information in a written format.
Patients (n = 160) referred for radiologic examination with intravenous contrast material were block randomized (sex, age, and previous exposure to contrast material) into two groups and were provided either written or computer-based (video) informed consent.
The female patients in the video group scored better on the test than those in the group with the written consent form. Male patients attained equivalent scores with both types of consent. The video took an average of 1.6 minutes longer to complete, probably because the majority of patients chose to be informed of every risk of intravenous contrast material.
This project demonstrates that a video format for informed consent before use of intravenous contrast material offers a good alternative to the written consent form.
评估使用造影剂时基于计算机的交互式知情同意书与书面形式的相同信息相比的效果。
将因静脉注射造影剂而接受放射学检查的患者（n = 160）按性别、年龄和既往造影剂暴露情况进行整群随机分组，分为两组，分别提供书面或基于计算机的（视频）知情同意书。
视频组的女性患者在测试中的得分高于书面同意书组的女性患者。男性患者在两种类型的同意方式下得分相当。完成视频平均多花费1.6分钟，可能是因为大多数患者选择了解静脉造影剂的每一项风险。
该项目表明，静脉注射造影剂前使用视频形式的知情同意书是书面同意书的一个良好替代方案。
