Abstract

PURPOSE

The purpose of this study was to test the hypothesis that video informed consent improves knee arthroscopy patient comprehension and satisfaction compared with traditional verbal informed consent.

TYPE OF STUDY

Prospective, randomized controlled trial.

METHODS

Consecutive patients having informed consent in preparation for knee arthroscopy by a single surgeon were stratified by educational level < or =12th grade or greater than 12th grade, then randomized to video or traditional verbal informed consent groups. Immediately after the informed consent process, patients completed an outcome questionnaire evaluating comprehension and satisfaction.

RESULTS

Patients in the video group showed significantly higher comprehension (78.5%) than patients in the verbal group (65.4%) (P = .00001). In the subgroup with < or = 12th grade education level, the video patients scored 73.1% comprehension and the verbal patients only 54.2% (P = .0011). In the subgroup with greater than 12th grade education level, the video patients scored 82.3% and the verbal patients scored 72.2% (P = .0002). There was no significant difference in subjective self-assessment of satisfaction between groups.

CONCLUSIONS

Video informed consent improves knee arthroscopy patient comprehension compared with traditional verbal informed consent.

LEVEL OF EVIDENCE

Level I.

摘要

目的

本研究的目的是检验与传统口头知情同意相比，视频知情同意可提高膝关节镜检查患者的理解度和满意度这一假设。

研究类型

前瞻性随机对照试验。

方法

由一名外科医生为准备接受膝关节镜检查的连续患者进行知情同意，根据教育水平（≤12年级或高于12年级）进行分层，然后随机分为视频知情同意组或传统口头知情同意组。在知情同意过程结束后，患者立即完成一份评估理解度和满意度的结果问卷。

结果

视频组患者的理解度（78.5%）显著高于口头组患者（65.4%）（P = 0.00001）。在教育水平≤12年级的亚组中，视频组患者的理解度得分为73.1%，口头组患者仅为54.2%（P = 0.0011）。在教育水平高于12年级的亚组中，视频组患者得分为82.3%，口头组患者得分为72.2%（P = 0.0002）。两组之间在满意度的主观自我评估方面无显著差异。
