Advancing Innovation in Dermatology is pleased to make available our collection of scholar articles, industry news, and interviews with the professionals accelerating innovation in skin health and patient care. This content is yet another way beyond our in-person and virtual events to strengthen the community of innovators we aim to build and maintain.

It encompasses hardware (mobile phones, wearable sensors), software (AI, machine learning, mobile phone apps), and digital communication platforms (telemedicine, text, email) to improve health.
Over the past three years, digital health has seen tremendous growth with many firsts. The first artificial intelligence technology was approved by the FDA (IDx-DR) for the diagnosis of diabetic retinopathy based on retina images in 2018. While there are many clinical decision software systems approved by the FDA, IDx-DR is the first that operates completely without the need for further physician interpretation.
The pivotal trial of the system included more than 11,000 images from 5000 patients showing specificity and sensitivity that exceeded 90% 1. There are now FDA-approved mobile apps that treat opioid addiction (2017)2 and contraception3 (2018). ABILIFY MYCITE®, approved by the FDA in 2017 as a drug-device combination, represents the first digital medicine designed to track drug ingestion. In 2018, Otsuka, the makers of Abilify, and Proteus, the makers of the ingestible sensor, agreed to an expanded five-year digital pill partnership.4
Dermatology has been an active area for digital health and a key beachhead. AI has already been shown to demonstrate equal — and even slightly better — performance to board-certified dermatologists in diagnosing skin cancer.5
Apps for melanoma detection have a checkered past—Mole Detective, for instance, was marketed to be able to diagnosis melanoma and faced fines from the Federal Trade Commission for doing so. SkinVision, available only in Europe currently, has a CE-mark and boasts more than one million users with nearly 3.5 million images. The company is focused on skin cancer with an initial assessment done via software with a high-risk assessment leading to a review by a dermatologist. For challenging rashes and inflammatory skin diseases, VisualDx released a consumer app in 2018 called AYSA that uses machine learning to identify inflammatory skin conditions and make preliminary recommendations for self-help and treatment.6 These innovations represent important examples of how digital health is impacting dermatology.
While there is no shortage of articles that predict the demise of physicians, digital health is so much more than simply replacing doctors with an algorithm. The demand for dermatological services far exceed the supply of board-certified dermatologists — the practice of dermatology by non-dermatologists leads to significantly higher diagnostic error.7
Digital health has an opportunity to close that gap by improving patient triage to dermatologists. Even if AI and mobile applications can detect suspicious lesions or recommend biopsy, a dermatologist is still needed to discuss the procedure, perform the procedure, and handle the aftermath with regard to the need for further testing or treatment options.
Non-diagnostic mobile phone applications have the opportunity to drive greater patient engagement by offering more education beyond what little time we have with our patients and even deliver behavioral health interventions to address the significant psychiatric comorbidities associated with dermatological diseases. Wearable sensors and the data they produce can drive far deeper insights on the impact of skin disease on daily life and track changes in a naturalistic setting.
Through engagement with digital health, dermatologists can direct implementation that best improves patient care.
