Development of a Broadband Telehealth System for Critical Care: Process and Lessons Learned

A broadband telehealth system has been developed for supporting critical care services between a major referral hospital and a rural hospital by transmitting very high-quality, realtime multimedia information, including images, audio and real-time video, over an Internet Protocol (IP)-based network. The technical design team took an iterative and user-centred approach toward the system design. Usability tests with scenario analysis were incorporated into the development process to produce a system that operates seamlessly in the critical care environment. Careful analysis of the reliability of the system was incorporated into the clinical protocols for integration into existing work practices. The use of high-quality multimedia data, consideration of human factors early in the design process, and incorporation of proper development approaches were critical for the success of the system design.
