OBJECTIVE
To ascertain whether a written information sheet is acceptable to patients and improves recall of the consent interview.
DESIGN
Prospective randomised controlled study using questionnaires, comparing a group of patients given information in a written sheet with appropriate explanation to a group given verbal information alone.
SETTING
A specialist orthopaedic surgery unit.
PATIENTS
The test group was 126 patients undergoing revision or primary total hip arthroplasty; 65 patients were given information verbally, 61 patients were given written information.
OUTCOME MEASURE
Patients' recall of information given, tested with a questionnaire completed on admission (mean of 18 days later).
RESULTS
The patients receiving written information scored significantly higher (48% correct answers) than the patients receiving verbal information (38% correct answers).
CONCLUSIONS
Written information sheets contribute to the process of informed consent. As patients' recall of information is generally poor, the sheets may also be useful medicolegally, as a permanent record of what was discussed.
目的
确定书面信息单是否为患者所接受，并能否提高对同意治疗访谈内容的记忆。
设计
采用问卷调查的前瞻性随机对照研究，将一组收到附有适当解释的书面信息单的患者与另一组仅收到口头信息的患者进行比较。
地点
一个专业骨科手术科室。
患者
试验组为126例行翻修或初次全髋关节置换术的患者；65例患者收到口头信息，61例患者收到书面信息。
观察指标
通过患者入院时填写的问卷（平均18天后）来测试患者对所提供信息的记忆情况。
结果
收到书面信息的患者得分显著高于收到口头信息的患者（正确答案分别为48%和38%）。
结论
书面信息单有助于知情同意过程。由于患者对信息的记忆通常较差，这些信息单在医学法律方面也可能有用，可作为所讨论内容的永久记录。
