We developed a mobile, wireless videoconferencing system suitable for use in a hospital accident and emergency (A&E) department. Four consultants, eight junior doctors and 11 nurses working in the A&E department tested the system. Transmission of three types of data (audio, still images and video) was tested. The audio for the breath and heart sounds was judged to have some disturbance. One consultant rated the diagnostic quality as good and one rated it as fair. The quality of the still images was judged to be from fair to excellent. The quality of the video was rated as good. Possible interference between the wireless local-area network and various medical devices in the A&E department were examined, but none was detected. The four consultants who tested the system were very positive in their initial comments. Eight of the 11 nurses remained sceptical about its use. Of a total of 20 patients who answered a survey, 13 were slightly anxious about the use of the system to transmit their data to a distant point. Overall, the performance of the system was satisfactory for use in the A&E role.
