Cost-effectiveness of Store-and-Forward Teledermatology:A Systematic Review
Importance Teledermatology is a topical clinical approach being tested in Australia and elsewhere. With most dermatologists residing in metropolitan areas, teledermatology provides an apparent low-cost and convenient means of access for individuals living outside these areas. It is important that any proposed new addition to a health care system is assessed on the grounds of economic cost and effectiveness. Objective To summarize and evaluate the current economic evidence comparing store-and-forward teledermatology (S&FTD) with conventional face-to-face care. Evidence Review Search terms with appropriate amendments were used to identify S&FTD articles that included economic analysis. Six databases were searched, and title, abstract and full-text reviews were conducted by 2 researchers. References of all unique returned articles were searched by hand. The Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist was used to evaluate quality of the included articles. Findings Eleven articles were selected for inclusion, including 1 cost analysis, 4 cost-minimization analyses, 4 cost-effectiveness analyses, and 2 cost-utility analyses. CHEERS scores ranged from 7 to 21 out of a possible 24 points, with a median score of 17. Conclusions and Relevance Current evidence is sparse but suggests that S&FTD can be cost-effective. It appears to be cost-effective when used as a triage mechanism to reduce face-to-face appointment requirements. The cost-effectiveness of S&FTD increases when patients are required to travel farther distances to access dermatology services. Further economic research is required for the emerging S&FTD, which uses dermoscopes in combination with smartphone applications, as well as regarding the possibility and consequences of patients self-capturing and transmitting images
What do Australian dermatologists expect to be paid for store-and-forward teledermoscopy? A preliminary investigation
Introduction: Determining appropriate remuneration for teledermoscopy service is important because inadequate remuneration can be a barrier to practitioner uptake and participation. This study explores dermatologist remuneration expectations for a single lesion store-and-forward teledermoscopy consultation. Methods: Fourteen dermatologists participated in telephone interviews during May–June 2017. Questions regarding remuneration focused on a clinical scenario involving teledermoscopy of a single lesion suspected to be skin cancer. The initial scenario was an existing patient, with a provisional diagnosis of benign neoplasm from the images, to be followed-up with routine skin checks, taking three minutes to review. Participants indicated their remuneration expectation by selecting from an ascending array of pre-determined remuneration ranges. The question was repeated a further four times with one aspect of the scenario changed each time; consultation length, source (patient or general practitioner), required follow-up, and a new rather than existing patient. Participants were also asked how appropriate they thought teledermoscopy was for the scenario, and whether they would choose to undertake the consultation presented. Results: Nine dermatologists selected the AU91–120 remuneration ranges for the initial scenario. When given the opportunity to comment on teledermoscopy service provision in Australia, respondents reflected that it was a valuable, advanced dermatology service, but they would prefer face-to-face consultation with patients where possible to allow for a full body examination. Discussion: Dermatologists expect to be remunerated in the range of AU$61–120 for a single lesion store-and-forward teledermoscopy consultation when face-to-face examination is not possible
Technique standards for skin lesion imaging: a delphi consensus statement
IMPORTANCE Variability in the metrics for image acquisition at the total body, regional, close-up, and dermoscopic levels impacts the quality and generalizability of skin images. Consensus guidelines are indicated to achieve universal imaging standards in dermatology. OBJECTIVE To achieve consensus among members of the International Skin Imaging Collaboration (ISIC) on standards for image acquisition metrics using a hybrid Delphi method. EVIDENCE REVIEW Delphi study with 5 rounds of ratings and revisions until relative consensus was achieved. The initial set of statements was developed by a core group (CG) on the basis of a literature review and clinical experience followed by 2 rounds of rating and revisions. The consensus process was validated by an extended group (EG) of ISIC members through 2 rounds of scoring and revisions. In all rounds, respondents rated the draft recommendations on a 1 (strongly agree) to 5 (strongly disagree) scale, explained ratings of less than 5, and optionally provided comments. At any stage, a recommendation was retained if both mean and median rating was 4 or higher. RESULTS The initial set of 45 items (round 1) was expanded by the CG to 56 variants in round 2, subsequently reduced to 42 items scored by the EG in round 3, yielding an EG set of 33 recommendations (rounds 4 and 5): General recommendation (1 guideline), lighting (5), background color (3), field of view (3), image orientation (8), focus/depth of field (3), resolution (4), scale (3), color calibration (2), and image storage (1). CONCLUSIONS AND RELEVANCE This iterative process of ratings and comments yielded a strong consensus on standards for skin imaging in dermatology practice. Adoption of these methods for image standardization is likely to improve clinical practice, information exchange, electronic health record documentation, harmonization of clinical studies and database development, and clinical decision support. Feasibility and validity testing under real-world clinical conditions is indicated
Proposed technical guidelines for the acquisition of clinical images of skin-related conditions
IMPORTANCE Standardizing dermatological imaging is important to improve monitoring of skin lesions and skin conditions, ensure the availability of high-quality images for teledermatology, and contribute to the development of a robust archive of skin images to be used for research
Indocyanine Green (ICG) Lymphography Is Superior to Lymphoscintigraphy for Diagnostic Imaging of Early Lymphedema of the Upper Limbs
BACKGROUND: Secondary lymphedema causes swelling in limbs due to lymph retention following lymph node dissection in cancer therapy. Initiation of treatment soon after appearance of edema is very important, but there is no method for early diagnosis of lymphedema. In this study, we compared the utility of four diagnostic imaging methods: magnetic resonance imaging (MRI), computed tomography (CT), lymphoscintigraphy, and Indocyanine Green (ICG) lymphography. PATIENTS AND METHODS: Between April 2010 and November 2011, we examined 21 female patients (42 arms) with unilateral mild upper limb lymphedema using the four methods. The mean age of the patients was 60.4 years old (35-81 years old). Biopsies of skin and collecting lymphatic vessels were performed in 7 patients who underwent lymphaticovenous anastomosis. RESULTS: The specificity was 1 for all four methods. The sensitivity was 1 in ICG lymphography and MRI, 0.62 in lymphoscintigraphy, and 0.33 in CT. These results show that MRI and ICG lymphography are superior to lymphoscintigraphy or CT for diagnosis of lymphedema. In some cases, biopsy findings suggested abnormalities in skin and lymphatic vessels for which lymphoscintigraphy showed no abnormal findings. ICG lymphography showed a dermal backflow pattern in these cases. CONCLUSIONS: Our findings suggest the importance of dual diagnosis by examination of the lymphatic system using ICG lymphography and evaluation of edema in subcutaneous fat tissue using MRI

Tailors in 1950s Beijing: Private enterprise, career trajectories, and historical turning points in the early PRC
How new was the New China? This article explores the experience of Beijing tailors in the early years of the PRC in light of this question. After 1949, many long-established tailors simply continued to ply their trade in their old business premises, giving a strong impression of continuity in the social fabric of the city. They were increasingly challenged, however, by newcomers to the industry, including petty entrepreneurs who chose to invest in a socially useful trade, and the graduates of newly established sewing schools, usually women. Policy shifts from the New Democracy period through the "three anti" and "five anti" campaigns to the eve of the socialist transformation in 1956 affected old and new businesses, men and women, in different ways. Overall, the reduction in entrepreneurial freedoms that characterizes this period of Chinese business history was, in this sector of industry and commerce, most strikingly manifest in limitations on what tailors were licensed to make, which had effects on what Beijing people wore. From these various perspectives, 1949 can be seen to be a rather clear dividing line in the history of Beijing, but it was possibly a rather faint line at first, becoming darker and thicker as the 1950s progressed-or should that be "regressed?" © 2011 Higher Education Press and Springer-Verlag Berlin Heidelberg
Sharing the archive: Using web technologies for accessing, storing and re-using historical data
Historical data pose a variety of problems to those who seek statistically based understandings of the past. Quantitative historical analysis has been limited by researcher’s reliance on rigid statistics collected by individuals or agencies, or else by researcher access to small samples of raw data. Even digital technologies by themselves have not been enough to overcome the challenges of working with manuscript sources and aligning dis-aggregated data. However, by coupling the facilities enabled by the web with the enthusiasm of the public for explorations of the past, history has started to make the same strides towards big data evident in other fields. While the use of citizens to crowdsource research data was first pioneered within the sciences, a number of projects have similarly begun to draw on the help of citizen historians. This article explores the particular example of the Prosecution Project, which since 2014 has been using crowdsourced volunteers on a research collaboration to build a large-scale relational database of criminal prosecutions throughout Australia from the early 1800s to 1960s. The article outlines the opportunities and challenges faced by projects seeking to use web technologies to access, store and re-use historical data in an environment that increasingly enables creative collaborations between researchers and other users of social and historical data
