Abstract
Teledermatology holds great potential for revolutionizing the delivery of dermatology services providing equitable service to remote areas and allowing primary care physicians to refer patients to dermatology centres of excellence at a distance However before its routine application as a service tool its reliability accuracy and cost effectiveness need to be verified by rigorous evaluation Teledermatology can be applied in one of two ways it may be conducted in real time utilizing videoconferencing equipment or by store and forward methods when transmitted digital images or photographs are submitted with a clinical history While there is a considerable range of reported accuracy and reliability evidence suggests that teledermatology will become increasingly utilized and incorporated into more conventional dermatology service delivery systems Studies to date have generally found that real time dermatology is likely to allow greater clinical information to be obtained from the patient This may result in fewer patients requiring conventional consultations but it is generally more time consuming and costly to the health service provider It is often favoured by the patient because of the instantaneous nature of the diagnosis and management regimen for the condition and it has educational value to the primary care physician Store and forward systems of teledermatology often give high levels of diagnostic accuracy and are cheaper and more convenient for the health care provider but lack the immediacy of patient contact with the dermatologist and involve a delay in obtaining the diagnosis and advice on management It is increasingly likely that teledermatology will prove to be a significant tool in the provision of dermatology services in the future These services will probably be provided by store and forward digital image systems with real time videoconferencing being used for case conferences and education However much more research is needed into the outcomes and limitations of such a service and its effect on waiting lists as well as possible cost benefits for patients primary health care professionals and dermatology departments
