The technical performance of a telemedical system when used for remote trauma management was compared with face-to-face consultation. Two rooms, 20 yards apart, were linked telemedically in the same Accident & Emergency Department. Two hundred patients, with 'minor' and 'moderate' injuries, underwent the two types of consultation. The Accident & Emergency consultant marked physical parameters using a five-point pre-determined Likert scale. The following parameters were thought to be of excellent quality when compared to face-to-face consultation: overhead fluorescent lighting for the background illumination, video lighting for a close-up view, sound quality after volume adjustment, echo-cancellation after adjustment and lip synchronization. However, the following parameters scored poorly: sound before volume adjustment, echo-cancellation before adjustment, fine and coarse movements. It can be concluded that the quality of lighting and image quality are good in telemedicine. Sound and movement still present some problems. This technology is likely to be used more frequently for remote trauma management.
