Abstract

BACKGROUND/AIMS: Telemedicine is a useful tool for remote education to overcome limitations of location. We have shared medical knowledge by the use of a real-time, high quality digital video transfer system (DVTS). The study aim was to evaluate the use of the DVTS by viewer questionnaire.
METHODS
After an endoscopic live demonstration using DVTS and satellite broadcasting system (SBS), questions were provided for the degree of satisfaction about image and sound of the presentation. A questionnaire was composed of 11 questions concerning factors such as a comparison of image quality between the two systems. The preference between DVTS with SBS was analyzed.
RESULTS
For image quality, SBS was more preferable than DVTS (65.6% versus 16.7%). However, 16.7% found no difference between the use of DVTS and SBS. For the time delay between the image and sound, 62.5% preferred SBS and 11.5% preferred DVTS. The satisfaction for combining DVTS with SBS were 68% as good and 22% as very good.
CONCLUSIONS
We have demonstrated the feasibility of telemedicine by the demonstration of a satisfactory teleconference, although DVTS was utilized as an assistant tool. DVTS should prove to be a promising tool as a useful and economic means to provide remote medicine.
