“…Several studies showing the feasibility and usefulness of e-visits in dermatology have already been described in the literature, and a high accordance for diagnosis between live visits and e-consultations has been reported in all of them [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]. Most of these studies demonstrate high accordance for the diagnosis of inflammatory and neoplastic skin diseases [17, 18, 19, 20, 21], and particularly for the diagnosis of pigmented skin lesions (teledermoscopy) [22, 23, 24, 25, 26].…”

Background: The treatment of chronic leg ulcers requires frequent assessments of local wound status and adjustment of therapy. The availability of reasonably priced photographic equipment and quick electronic transfer of high-quality digital images should make it possible that the assessment of wound status can be made by remote experts. Objective: This study examines the feasibility of using teledermatology for wound assessment and therapeutic suggestions for patients with chronic leg ulcers. Methods: One hundred ten chronic leg ulcers of different origins were examined in face-to-face consultations. The examining doctor assessed the wound, made therapeutic recommendations and took 1–4 photographs of the wound using a digital camera. The digital images and relevant clinical information were then transmitted via a web application to an expert in wound care, who provided an independent teledermatological assessment of wound status and therapeutic recommendations. Results: In our study, a high accordance between direct consultations and electronic consultations was found in the assessment of chronic leg ulcers, especially for important features like slough (concordance: 84.6%), necrosis (concordance: 98.2%) and granulation tissue formation (concordance: 76.4%). Furthermore, the teledermatologist generally felt confident in recommending further treatment strategies and in planning further wound assessments via the internet. Conclusions: Our results suggest that teledermatology offers great potential for the future in chronic wound care. By reducing the need to travel long distances to the hospital or to consult a physician with expertise in wound care, wound teleconsultation might lower health care costs and improve the quality of life for patients with chronic wounds, while still maintaining a high quality of wound care.

“…Baumeister et al [12] tested and compared two validated scores (Osnabrück Hand Eczema Severity Index; Hand Eczema Severity Index) for their suitability in an occupational telemedical screening and showed that both scores were suitable to asses severity of hand eczema by teledermatology. Nordal et al [13 ]compared the diagnoses made by one dermatologist via telemedicine with those of another dermatologist made in face-to-face consultation. Of 121 patients, there was a high degree of concordance between the two sets of diagnoses, with 72% complete agreement and 14% partial agreement between the two dermatologists [13].…”

Background: Different scoring systems have been developed to determine the severity of atopic dermatitis (AD); the SCORAD (Scoring Atopic Dermatitis) and EASI (Eczema Area and Severity Index) are among the best-validated scoring systems. Objective: The aim of this study was to produce a rational quality control for routine clinical use by using the modern facilities of digital imaging. Methods: 63 AD patients were scored by a single person at each visit using the SCORAD and EASI scoring methods. Images were taken and rated by two non-dermatology physicians trained in the scoring system. In addition, blood samples were taken for the determination of total IgE, eosinophils and eosinophilic cationic protein. Results: The EASI score established from the digital images, hereby named ‘EASIdig’, correlated at all visits with the results of the SCORAD and EASI. Together with immunological parameters, they also reflected changes of disease severity during the 3 time points. Conclusion: The digital evaluation of the EASI is a reliable tool for the digital assessment of severity and extent of AD.

“…8 Another study also found no differences in diagnostic accuracy with a compression factor of 30 but determined the reproducibility of diagnostic judgment was greater with images uncompressed. 9 Fourteen percent of diagnoses were adversely affected by picture quality in a videoconferencing study, 10 whereas other studies indicate video quality may be inadequate for some exams 11 and inferior to still images. 12 Several studies have suggested there may be a minimal compression and transmission threshold.…”

Uncompressed high-definition (HD) video image quality is superior to compressed HD video provided in most commercially available videoconferencing products. Uncompressed HD videoconferencing tools provide a more immersive experience because there is no reduction of image information and, in most cases, lower latency. Four open source uncompressed video applications are reviewed that have been tested at the National Library of Medicine: three transmitting uncompressed HD video and one transmitting loosely compressed standard-definition video. The technical requirements for implementing each are described, and test results in terms of image quality, latency, and application reliability are presented. Because the hardware and bandwidth requirements for uncompressed HD video are relatively high and most applications are still under development, they are generally not ready for mass deployment. Some are, however, ready for pilot testing and experimentation in clinical settings by either those who have or anticipate having bandwidth sufficient to support them or those interested in researching the effects higher-quality video may have on diagnostic and other clinical outcomes.
