Abstract
Dermatologists are mostly confined to urban regions and rural population is deprived of specialist care. Teledermatology Practice (TDP) is a solution to overcome this global problem. Tools for TDP includes video conference, store and forward, hybrid, mobile, satellite communication, integration model, nurse‐led teledermatology, teledermatology focusing on difficult‐to‐manage cases, teledermoscopy, and teledermatopathology with combined applications. This article reviews the feasibility studies focusing teledermatology tools and analyses the possible options in designing TDP. Categorizing dermatoses for TDP depends on the purpose and types of technology. The dermatoses presenting from a remote geographic regions requires any of the following approaches (i) only TDP, (b) initial TDP followed by face‐to‐face, (iii) initial face‐to‐face followed by TDP and (iv) only face‐to‐face examination. The technology should suit the dermatoses, meet the purpose, be cost‐effective and provide better management with follow‐up care. We recommend store and forward as a basic TDP model as most dermatoses are diagnosed and follow‐up care is delivered. Leprosy, pigmented skin lesions, leg ulcers, HIV and endemic dermatoses require screening and triage services using mobile teledermatology. Counselling and education require videoconference. Rural dermatology's camps require satellite communication mounted on a vehicle. Objective assessment (vitiligo and leg ulcer) after treatment requires integration model at a tertiary centre. Difficult‐to‐manage cases require second opinion using hybrid/store and forward TDP. Lower rural centre are provided with mobile/ store and forward teledermatology services. Selected or major community centre should be equipped with hybrid teledermatology and linked to a tertiary centre. This process helps healthcare administration to plan a TDP to cover all dermatoses, utilizing the available health care professional (HCP) and technology with minimum budget investment.Conflicts of interest: None declared.
