目的：评估在临床环境中使用个人数字助理（PDA）上显示的视听动画（即数字视频）对患者进行教育的效果。方法：在某学术医疗中心传染病门诊进行前瞻性技术干预的准实验研究。受试者在观看PDA上的数字视频之前、之后和4-6周后立即回答问题。结果测量包括参与者的疾病知识、药物知识和依从性行为知识；对视频和PDA的态度；自我报告的依从性;以及干预的实用性。结果：51名说英语的成年人参加了这项研究，他们正在开始或正在服用治疗HIV/AIDS的药物。在第一次就诊时，在观看了基于pda的视频后，对疾病知识（p < 0.005；配对t检验）、药物知识（p < 0.005；配对t检验）和依从性行为知识（p < 0.05；方差分析）进行了统计上显著的改善。在就诊2周（4-6周后），自我报告对药物治疗方案的依从性有统计学显著改善（p < 0.005；配对t检验）。参与者喜欢基于掌上电脑的视频，并表示这是一种合适的学习媒介，无论他们的基本读写能力如何。视频教育过程估计需要25分钟的参与者时间，并在私人和半私人地点观看。结论：通过PDA传送数字视频的技术辅助教育是一种方便且潜在强大的健康信息传递方式。干预措施在不同年龄和教育水平的参与者中有效实施，并在临床环境的一系列地点进行。有必要进一步研究这种方法。2006爱思唯尔爱尔兰有限公司版权所有。
Objectives: To evaluate the effects of using an audiovisual animation (i.e., digital video) displayed on a personal digital assistant (PDA) for patient education in a clinical setting.Methods: Quasi-experimental study of a prospective technology intervention conducted in an outpatient infectious diseases clinic at an academic medical center. Subjects responded to questions immediately before, immediately after, and 4-6 weeks after watching a digital video on a PDA. Outcome measures include participant knowledge of disease, knowledge of medications, and knowledge of adherence behaviors; attitudes toward the video and PDA; self-reported adherence; and practicality of the intervention.Results: Fifty-one English-speaking adults who were initiating or taking medications for the treatment of HIV/AIDS participated in the study. At visit one, statistically significant improvements in knowledge of disease (p < 0.005; paired t-test), knowledge of medications (p < 0.005; paired t-test), and knowledge of adherence behaviors (P < 0.05; ANOVA) were measured after participants watched the PDA-based video. At visit two (4-6 weeks later), statistically significant improvements in self-reported adherence to the medication regimens (p < 0.005; paired t-test) were reported. Participants liked the PDA-based video and indicated that it was an appropriate medium for learning, regardless of their baseline literacy skills. The video education process was estimated to take 25 min of participant time and was viewed in both private and semi-private locations.Conclusions: Technology-assisted education using a digital video delivered via PDA is a convenient and potentially powerful way to deliver health messages. The intervention was implemented efficiently with participants of a variety of ages and educational levels, and in a range of locations within clinical environments. Additional study of this methodology is warranted. (C) 2006 Elsevier Ireland Ltd. All rights reserved.
