The study's objectives were to measure patients' perceptions of a telehomecare system before and after they have participated in it and identify the features of the system that patients perceived differently after experiencing it. The study setting was the TeleHomeCare Project, which uses videoconferencing and Internet equipment to enable interactions between patients and nurses. An instrument that measures perceptions of telehomecare was used. Patients viewed a videotape that demonstrates a "virtual home care visit" and filled out the questionnaire (pre-test). They were then randomly assigned to a control group receiving standard care or to an experimental group receiving videoconferencing and Internet access in addition to standard care. Both groups filled out the questionnaire when exiting the system (post-test). Paired t-tests were performed to compare total scores and responses to each of the items within the groups and an unpaired t-test was used to compare change of perceptions between groups. The control group consisted of 11 patients, and the experimental group included 17 patients. There was no statistically significant change of perception in the control group. The experimental group showed an overall more positive perception of the system after their experience (total score increase by 6.059, p < 0.0001), and the mean score difference was higher compared to the control group (mean 6.241, p < 0.0001). Elderly patients evaluated their telehomecare experience as being positive, and they felt more comfortable with the technology, believing that the nurse can understand their medical problem over the television. This suggests that telehomecare has the potential for wide acceptance among patients.
该研究的目的是测量患者在参与远程家庭护理系统前后对其的看法，并确定患者在体验该系统后感知不同的系统特征。研究背景是远程家庭护理项目，该项目使用视频会议和互联网设备实现患者与护士之间的互动。使用了一种测量对远程家庭护理看法的工具。患者观看了一段展示“虚拟家庭护理访视”的录像带并填写问卷（预测试）。然后他们被随机分为接受标准护理的对照组或除标准护理外还接受视频会议和互联网接入的实验组。两组在退出系统时都填写了问卷（后测试）。进行配对t检验以比较组内总分和对每个项目的回答，并使用非配对t检验比较组间看法的变化。对照组由11名患者组成，实验组包括17名患者。对照组在看法上没有统计学上的显著变化。实验组在体验后对该系统总体上有更积极的看法（总分增加6.059，p < 0.0001），并且与对照组相比平均得分差异更高（平均6.241，p < 0.0001）。老年患者对他们的远程家庭护理体验评价为积极，他们对该技术感觉更自在，相信护士可以通过电视了解他们的医疗问题。这表明远程家庭护理在患者中具有广泛接受的潜力。
