The assessment of the potential effect of a commercial teledermatology system.  The system allowed general practitioners to send dermatologists a set of digital images, accompanied by a short patient history.  Patients were seen, in the normal way, by consultant dermatologists.  The system was then used to capture a set of images.  These were viewed by two dertmatologists, 13 months later.  Reasonably high levels of agreement were found between the dermatologist seeing the  patient and the dermatologist using the telemedicine system (77%).  It was found that this system would therefore not lead to significant savings, nor reduce the waiting list for outpatient appointments.  The idea would have potential if the review of images could be made as easy and the triage of referral letters.
