Skin Deep - A Dermatology Blog

Skin Deep is a blog created for dermatologists to allow free flow of information on topics and events relating to dermatology. Having comments on-line also has the advantage of allowing for further discussion and clarification if needed on various topics. However it is left to the reader to filter and judge the value of the comments. As the archives continue to accumulate, probably at some point they will become a useful reference for all. Contact Dr Bell Eapen for details.

Have you ever wondered why you have to wait for a dermatology appointment to show a small rash or skin lesion on your body and get the appropriate treatment when you have all the latest technology to acquire, store and transmit high quality digital images? In some cases, the rash may have subsided by the time you get your dermatologist’s appointment. Often times, your GP may not be able to help you since they don’t get specific training in dermatology.  Teledermatology may be just the right solution to increase access to highly qualified skin specialists. There are two different models in teledermatology. Store and Forward (SAF) model and Real Time (RT) interactive model. A combination of both models also exist. SAF model is more popular as it is easy to implement and less expensive. It involves acquiring the digital image of the lesion and forwarding it to the data storage unit of the consultant along with relevant medical details. Though It can even be sent as an email attachment, it is not preferred because of the associated data security concerns as discussed below. In RT model the consultant interacts with the patient via live videoconferencing. It requires more sophisticated and expensive equipment and both participants should be available at the same time. But the accuracy of diagnosis may be marginally better with RT model compared to SAF model. Teledermatology can also be used for specialist referral when the general practitioner seeks a second opinion from a specialist and in medical education. The other areas where teledermatology can be effectively used include providing expert follow-up care for patients with chronic skin diseases and prioritising patients for urgent care when there is a long wait time.
