Store-and-forward teledermatology results in similar clinical outcomes to conventional clinic-based care.
ABSTRACT We compared the clinical outcomes after store-and-forward teledermatology with those following conventional clinic-based consultation. Subjects were randomized to either usual care (a conventional clinic-based dermatology appointment) or a store-and-forward teledermatology consultation. All subjects received baseline digital imaging and re-imaging was performed four months later. A total of 776 subjects were approached for inclusion, and a total of 508 image sets were reviewed, 236 in usual care and 272 in teledermatology. The image sets from both study arms were used to make clinical outcome assessments between baseline and four months. A dermatologist who was blinded to the randomization rated the clinical outcomes using a three-point clinical course rating scale (1 = improved, 2 = no change, 3 = worse). In the usual care group, 65% were rated as 'improved', 32% were rated as 'no change' and 3% were rated as 'worse'. For teledermatology, 64% were rated as 'improved', 33% as 'no change' and 4% as 'worse'. The results of the study indicate that store-and-forward teledermatology consultations produce similar clinical outcomes when compared with conventional clinic-based consultations.

ABSTRACT: Telemedicine is increasingly being used as part of routine practice for many physicians and healthcare providers across the country. Due to its visual nature, dermatology is ideally suited to benefit from this new technology. The use of teledermatology (telemedicine in dermatology) in a primary care setting allows for an expert opinion without the need for an in-person referral. Furthermore, it can improve patient access in remote areas. Store-and-forward teledermatology is the most commonly employed method.BMC Research Notes 09/2014; 7(1):588.

ABSTRACT: Background Non-melanoma skin cancer (NMSC) is one of the most common neoplasms in the world. Despite the low mortality rates, NMSC can still cause severe sequelae when diagnosed at advanced stages. Malignant melanoma, the third most common type of skin cancer, has more aggressive behavior and a worse prognosis. Teledermatology provides a new tool for monitoring skin cancer, especially in countries with a large area and unequal population distribution.This study sought to evaluate the performance of digital photography in skin cancer diagnosis in remote areas of Brazil.MethodsA physician in a Mobile Prevention Unit (MPU) took four hundred sixteen digital images of suspicious lesions between April 2010 and July 2011. All of the photographs were electronically sent to two oncologists at Barretos Cancer Hospital who blindly evaluated the images and provided a diagnosis (benign or malignant). The absolute agreement rates between the diagnoses made by direct visual inspection (by the MPU physician) and through the use of digital imaging (by the two oncologists) were calculated. The oncologists¿ accuracy in predicting skin cancer using digital imaging was assessed by means of overall accuracy (correct classification rate), sensitivity, specificity and predictive value (positive and negative). A skin biopsy was considered the gold standard.ResultsOncologist #1 classified 59 lesions as benign with the digital images, while oncologist #2 classified 27 lesions as benign using the same images. The absolute agreement rates with direct visual inspection were 85.8% for oncologist #1 (95% CI: 77.1-95.2) and 93.5% for oncologist #2 (95% CI: 84.5-100.0). The overall accuracy of the two oncologists did not differ significantly.Conclusions Given the high sensitivity and PPV, Teledermatology seems to be a suitable tool for skin cancer screening by MPU in remote areas of Brazil.BMC Dermatology 12/2014; 14(1):1.
