Patient-assisted teledermatology practice: what is it? When, where, and how it is applied?

Recent teledermatology practice has been focused on different models made possible by robust advances in information technology leading to consistent interaction between the patient and health care professionals. Patient-assisted teledermatology practice also called patient-enabled teledermatology or home based teledermatology is one such novel model. There is a lack of scientific literature and substantive reviews on patient-assisted teledermatology practice. The present article reviews several studies and surveys on patient-assisted teledermatology practice and outlines its advantages and barriers to clinical utility and analyses the potentiality of this concept. Incorporating patient-assisted teledermatology practice as a novel model in the revised classification of teledermatology practice is proposed. In patient-assisted teledermatology, the patient can upload his/her clinical images as a first contact with the dermatologist or an initial face-to-face examination can be followed by teledermatology consultations. The latter method is well suited to chronic diseases such as psoriasis, vitiligo, and leg ulcers, which may need frequent follow-up entailing significant costs and time, particularly in the elderly. Teledermatology may also be used by the treating dermatologist to seek expert opinion for difficult cases. Studies have demonstrated the importance and usability of the concept of patient-assisted teledermatology practice. Various teledermatology care models are available and the appropriate model should be chosen depending on whether the clinical situation is that of easily diagnosed cases ("spotters"), chronic cases or doubtful cases and difficult-to-manage cases.

Teledermatology, Teledermatopathology, Interstate Dermatopathology and the Law

The expansion of telemedicine nationwide has resulted in many states adopting specific telemedicine regulations to avoid the issue of requiring a full medical license to practice telemedicine. How these laws and regulations relate to the practice of telepathology and teledermatology has not been well delineated. It is important to understand these regulations to avoid potential judicial penalties arising from non-compliance. This article aims to outline state-specific telemedicine regulations and penalties.

Pediatric Teledermatology Consultations: Relationship Between Provided Data and Diagnosis

There is a shortage of pediatric dermatologists. Teledermatology has emerged as a tool to facilitate access to dermatologists. Many questions remain regarding how to optimize consultations in order to provide the best diagnosis and management recommendations. The aim of this retrospective cohort study was to categorize the historical data and judge the adequacy of photographs sent by referring providers to our academic pediatric teledermatology practice at the University of California, San Francisco, and to evaluate the relationship of these data to our ability to render a diagnosis. A diagnosis was rendered in 75% of cases. The only historical data associated with receiving a diagnosis was prior treatment (OR 2.01, CI 1.01, 4, p < 0.05). Appropriate image distance from the target was associated with receiving a diagnosis for rashes (OR 2.69, CI 1.07, 6.8, p = 0.04) and growths (OR 4.16, CI 1.04, 16.6, p = 0.04). A lack of diagnosis was significantly associated with a recommendation for referral for biopsy (OR 0.03, CI 0.01, 0.10, p < 0.0001) or for in-person consultation (OR 0.19, CI 0.05, 0.66, p < 0.001). In conclusion, pediatric teledermatologists are able to make a diagnosis most of the time, regardless of historical information provided or image quality. The rate of diagnosis may be improved with the use of standardized templates for historical information. Similarly, photography training could minimize the need for in-person consultation. Specific information regarding prior treatments could also help in providing useful management recommendations.

A longitudinal study of consistency in diagnostic accuracy of teledermatology tools

Diagnostic accuracy (DA) is an outcome measure to assess the feasibility of teledermatology tools. Despite ample data with variable DA values, no study has examined the aggregate DA value obtained from the available studies and observed its consistency over a period of time. This kind of a longitudinal study about teledermatology will be necessary to check its usefulness and plan for further implementation. To observe the DA trend over a period of 15 years (1997-2011). Only those studies (n = 59) using a single tool for general, tertiary, and subspecialty teledermatology practice were included to obtain the DA values. Studies were graded based on the number of subjects and gold standard comparison between teledermatologist and clinical dermatologist (face-to-face examination). This analysis sought to identify the DA trend was carried out by evaluating 17 store and forward teledermatology (SAFT) based and 8 Video conference (VC) tool-based studies with 2385 and 1305 patients respectively, in comparison with the gold-standard assessment. The average DA was 73.35% ± 14.87% for SAFT and 70.37% ± 7.01% for VC. One sample t-test analysis with 100% accuracy as standard value revealed 28% deficiency for SAFT (t = 7.925; P = 0.000) and 30% deficiency for VC (t = 11.955; P = 0.000). Kruskall-Wallis test confirmed the consistency of DA values in the SAFT (χ2 = 1.852, P = 0.763) tool. SAFT and VC were adequately validated on a large number of patients by various feasibility studies with the gold standard (face-to-face) comparison between teledermatologists and clinical dermatologists. The DA of SAFT was good, stable over the 15 years and comparable to VC. Health-care providers need to plan for appropriate utility of SAFT either alone or in combination with VC to implement and deliver teledermatology care in India.

Teledermatology update: Mobile teledermatology

Mobile teledermatology is a relatively recent modifica tion of teledermatology, which involves using mobile platforms like cellular phones to transmit images and data for the purpose of teleconsultations. With the rapidly improving quality of smart phone cameras combined with easier access to mobile internet, mobile teledermatology is emerging as a feasible and costeffective method for teledermatology practice. Mobile teledermatology has shown good results in concordance studies comparing it to face-to-face consultations. Mobile teledermatology can be used for most types of clinical dermatology cases. Mobile teledermatology has been found to be useful in diagnosis, screening and triage of skin lesions including skin cancers. It is also useful as a tool to follow up patients with chronic dermatological problems like psoriasis and chronic wounds. The obvious advantage of mobile teledermatology is it’s cost-effectiveness and the fact that access to expert dermatology care is made easier for patients especially in remote areas. Further research is however required to standardize protocols for mobile teledermatology. Collaborative research among people working in this field would be very useful in this standardization and would help in optimizing the opportunities provided by this interesting tool. This article gives a brief overview of mobile teledermatology including definitions, tools involved, indications, limitations and future applications.

Teledermatology: A Tool for Nurse Practitioner Practice?

Teledermatology is the practice of dermatology from a distance and can be used in several ways. This emerging technology has the potential to impact the current health care delivery system and provide dermatology care to a greater number of patients in underserved areas. Current research shows that the diagnostic concordance rates and accuracy rates are high, but there are also limitations with teledermatology use. Nurse practitioners have the potential to become active participants in the practice of teledermatology and ensure the provision of dermatology services to underserved populations.

Practice models and challenges in teledermatology: a study of collective experiences from teledermatologists.

BackgroundDespite increasing practice of teledermatology in the U.S., teledermatology practice models and real-world challenges are rarely studied.MethodsThe primary objective was to examine teledermatology practice models and shared challenges among teledermatologists in California, focusing on practice operations, reimbursement considerations, barriers to sustainability, and incentives. We conducted in-depth interviews with teledermatologists that practiced store-and-forward or live-interactive teledermatology from January 1, 2007 through March 30, 2011 in California.ResultsSeventeen teledermatologists from academia, private practice, health maintenance organizations, and county settings participated in the study. Among them, 76% practiced store-and-forward only, 6% practiced live-interactive only, and 18% practiced both modalities. Only 29% received structured training in teledermatology. The average number of years practicing teledermatology was 4.29 years (SD±2.81). Approximately 47% of teledermatologists served at least one Federally Qualified Health Center. Over 75% of patients seen via teledermatology were at or below 200% federal poverty level and usually lived in rural regions without dermatologist access. Practice challenges were identified in the following areas. Teledermatologists faced delays in reimbursements and non-reimbursement of teledermatology services. The primary reason for operational inefficiency was poor image quality and/or inadequate history. Costly and inefficient software platforms and lack of communication with referring providers also presented barriers.ConclusionTeledermatology enables underserved populations to access specialty care. Improvements in reimbursement mechanisms, efficient technology platforms, communication with referring providers, and teledermatology training are necessary to support sustainable practices.

Overview of international teledermatology

Teledermatology is essentially "dermatology at a distance", using one of many communication technologies to expand the reach of a dermatologist to those in need of their specialized knowledge. Most international teledermatology is store-and-forward in nature, a method in which images are stored on a computer and then transmitted electronically to a consulting dermatologist. This system is more convenient and less costly than real-time teledermatology. This review will focus on several of the store-and-forward teledermatology systems being developed and utilized successfully internationally. This discussion of "who" is practicing teledermatology is not comprehensive, but attempts to show some of the breadth of teledermatology practice around the world, including government national health plans, commercial endeavors, and charitable work by individuals and institutions. The goal in many instances is to provide better health outcomes through increased access, efficiency, and/or cost-effectiveness. More studies ultimately need to be conducted to develop a more comprehensive and sustainable model for teledermatology.

Newer insights in teledermatology practice

The study and practice of dermatology care using interactive audio, visual, and data communications from a distance is called teledermatology. A teledermatology practice (TP) provides teleconsultation as well tele-education. Initially, dermatologists used videoconference. Convenience, cost-effectiveness and easy application of the practice made "store and forward" to emerge as a basic teledermatology tool. The advent of newer technologies like third generation (3G) and fourth generation (4G) mobile teledermatology (MT) and dermatologists' interest to adopt tertiary TP to pool expert (second) opinion to address difficult-to-manage cases (DMCs) has resulted in a rapid change in TP. Online discussion groups (ODGs), author-based second opinion teledermatology (AST), or a combination of both are the types of tertiary TP. This article analyzes the feasibility studies and provides latest insight into TP with a revised classification to plan and allocate budget and apply appropriate technology. Using the acronym CAP-HAT, which represents five important factors like case, approach, purpose, health care professionals, and technology, one can frame a TP. Store-and-forward teledermatology (SAFT) is used to address routine cases (spotters). Chronic cases need frequent follow-up care. Leg ulcer and localized vitiligo need MT while psoriasis and leprosy require SAFT. Pigmented skin lesions require MT for triage and combination of teledermoscopy, telepathology, and teledermatology for diagnosis. A self-practising dermatologist and national health care system dermatologist use SAFT for routine cases and a combination of ASTwith an ODG to address a DMC. A TP alone or in combination with face-to-face consultation delivers quality care.

Authors’ willingness for second‐opinion teledermatology in difficult‐to‐manage cases: ‘an online survey’

Expert non-availability for an instant difficult-to-manage case may limit the online discussion group to provide second-opinion teledermatology for registered dermatologists. Author-based second-opinion teledermatology (AST) is proposed and assessment of authors' response to answer queries and their willingness to participate in teledermatology consultation is analysed. Authors of 292 articles from seven non-open access dermatology and three general medical journals addressing difficult-to-manage cases from June 2007 to December 2008 participated in this online dermatology authors' survey. Authors' response to reprint requests, answer literature queries and willingness to offer second-opinion teledermatology were the main outcome measures. Perceived views were also documented. The scores for reprints requests vs. received were (chi(2) = 13.57, n = 292), P = 0.000. The scores for articles read, analysed and literature queries sent vs. authors answered were (chi(2) = 11.09, n = 190), P = 0.001. The scores for authors responded to reprints vs. willing to offer second-opinion teledermatology consultation were (chi(2) = 5.65, n = 190), P = 0.017 and authors responded to reprint requests, answered queries and willing to offer second-opinion (chi(2) = 5.65, n = 190), P = 0.017. A dermatologist obtains literature, answered queries and constructive suggestions with additional informative material and pools second-opinions from the authors using their e-mail to deliver quality health care. AST is an alternative to online discussion group for second-opinion teledermatology practice in difficult-to-manage cases. Uniform international laws are to be framed to facilitate telemedicine care for a difficult-to-manage case.

Classification and design of teledermatology practice: What dermatoses? Which technology to apply?

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.

Economic Evaluation of Interactive Teledermatology Compared with Conventional Care

Teledermatology offers a means of providing specialist care to underserved patients. The objectives of this study were to compare the costs of interactive teledermatology with conventional care, and to evaluate from a healthcare provider perspective whether interactive teledermatology is economically viable in the northeastern region of the United States. We studied the interactive teledermatology practice at Nantucket Cottage Hospital on Nantucket Island and the ambulatory clinics at the Massachusetts General Hospital in Boston, Massachusetts. The cost-minimization analysis compared the costs of an interactive teledermatology practice with that of a face-to-face dermatology clinic. One-way sensitivity analyses examined the effect of varying the costs of technology, physician compensation, or clinic space on the overall cost of interactive teledermatology. We also assessed the economic viability of the interactive teledermatology practice by comparing the operating costs with reimbursements. The total hourly operating costs for the interactive teledermatology practice on Nantucket Island and the face-to-face clinic in Boston were $274 and $346, respectively. Three separate one-way sensitivity analyses showed that, for the cost of the teledermatology practice to equal that of the conventional clinic, the cost of teledermatology technology could increase by 9.3-fold, dermatologists working at the teledermatology practice could be compensated up to $197 an hour, or the cost of teledermatology clinic space could reach $57 an hour. Our analysis also showed that the hourly reimbursement for the teledermatology practice was $487, which exceeded its hourly operating cost of $274. The cost of operating an interactive teledermatology practice in a remote region may be less than that of a conventional clinic in a nearby urban center in the northeastern area of the United States. From a healthcare provider perspective, interactive teledermatology can be an economically viable means of providing dermatological care to remote regions.
