What are the benefits of teledermatology? Teledermatology is a subspecialty of dermatology and probably among the most popular applications of e-health and telemedicine. In this field, telecommuncation technologies are being used to transfer medical information over varying distances through audio, visual and data communication. Applications of teledermatology span different areas of health care management such as consultation, diagnoses, treatment and even education.

Different Modes Of Data Transmission

There are two concepts which form the basis for the practice of teledermatology (as telemedicine): Store and forward, which is commonly abbreviated SAF, and real time or interactive teledermatology. The SAF and real time application methods can also be combined to form hybrid modes of data transmission.

In teledermatology, the SAF is often times the method of choice: The process involves sending or forwarding digital images linked with medical information to the data storage device of a specialist in the field. It can be as simple as sending an email inquiry with an attached digital image of a lesion to receive advice on how to treat the skin condition. The primary advantages of using this method are that it does not require both parties to be present at the same time and location and that no expensive equipment is necessary.

On the other hand, real time or interactive teledermatology entails the medical provider and the patient to interact through a live video conference. In some cases, a remote surgery may be involved as well as the use of telereobotic microscopes particularly when it comes to dermatopathology. This mode of data transmission is more expensive as sophisticated and costly technology must be used unlike in the store and forward mode. Both parties must also be available at the same time.
