Abstract
We carried out a retrospective review of the videoconference activity records in a university run hospital telemedicine studio Usage records describing videoconferencing activity in the telemedicine studio were compared with the billing records provided by the telecommunications company During a seven month period there were 211 entries in the studio log 108 calls made from the studio and 103 calls made from a far end location We found that 103 calls from a total of 195 calls reported by the telecommunications company were recorded in the usage log The remaining 92 calls were not recorded probably for one of several reasons including failed calls a large number of unrecorded calls 57 lasted for less than 2 min median 1 6 min origin of videoconference calls calls may have been recorded incorrectly in the usage diary i e as being initiated from the far end when actually initiated from the studio and human error Our study showed that manual recording of videoconference activity may not accurately reflect the actual activity taking place Those responsible for recording and analysing videoconference activity particularly in large telemedicine networks should do so with care
