Teledermatology: Using Technology to Diagnose and Treat Skin Conditions

Last updated: May 2018

Teledermatology is the skin branch of telemedicine, which is the use of telecommunication technology to relay audio, visual, and data information. Teledermatology can be a valuable tool for patients and doctors, especially for patients in rural areas that may not have easy access to a dermatologist. Teledermatology can be used to determine which patients need additional follow-up by a dermatology clinic, to diagnose skin conditions, and to manage care for chronic skin conditions, like psoriasis.1

There are two modalities for teledermatology: store-and-forward and live-interactive.

  • Store-and-forward is the sending (or forwarding) of digital images and patient
    information to a distant site provider; or the sending of information back to the patient.
  • Live-interactive is the patient sending images or interacting live directly with the dermatologist.2

The benefits of teledermatology

Teledermatology offers several benefits, including:

  • Reducing healthcare costs: Telemedicine reduces emergency room visits, which
    significantly reduces healthcare costs. Teledermatology can also provide quality care to patients at a lower cost.
  • Increasing access to medical care: Teledermatology enables virtual consultations with a dermatologist regardless of a patient’s geographic location.
  • Facilitating earlier diagnosis: Teledermatology enables skin problems to be addressed before they worsen or become more serious.
  • Aiding patient compliance: Teledermatology can improve patient compliance with
    recommended treatment and referral plans.2

The challenges of teledermatology

Teledermatology is an exciting field of medicine, and the number of practices offering these services is growing. However, there are some challenges. One of the critical factors is the quality of the images sent by patients. If the pictures aren’t of sufficient quality, including the lighting and focus of the image, the dermatologist doesn’t have the necessary information to provide a healthcare recommendation. Also, some healthcare plans aren’t yet equipped to reimburse for telemedicine services. Another challenge is the efficiency of the technology platform used by the dermatologist, which can impact both the doctor’s office and the patient.3

Patient satisfaction with teledermatology

Despite the challenges and the relative newness of the technology, studies have found that patients are very satisfied with teledermatology. One meta-analysis that evaluated 40 studies of telemedicine found that 96% of the studies that evaluated store-and-forward demonstrated patient satisfaction, and 89% of the studies that evaluated live-interactive demonstrated patient satisfaction. The physicians also showed a high satisfaction with the technology (82% satisfaction with store-and-forward and 100% with live-interactive).4

An exciting tool for skin care

Telemedicine, including teledermatology, has the potential to revolutionize the delivery of healthcare. Using technology for dermatology is especially useful due to the visual nature of skin conditions. While teledermatology will never replace in-person visits, it can provide another tool for people needing expert care for their skin conditions.
