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.
