Pediatric teledermatology--a survey of current use

Abstract:  Demand for pediatric dermatologic care far exceeds the supply of pediatric dermatologists. Teledermatology has been proposed as a solution to improve access to care, however, data regarding teledermatology use for pediatric patients are lacking. Surveys assessing use and experience with teledermatology were administered to pediatric dermatologists attending the 2006 Society for Pediatric Dermatology Annual Meeting and to programs offering teledermatology identified in the American Telemedicine Association's 2003 Teledermatology Survey. Over half of the 76 pediatric dermatologists responding to the survey had previous experience with teledermatology and nearly half currently use some form of teledermatology. For most, this represents nonreimbursed, store-and-forward consultations. Respondents noted that teledermatology allows more accurate triage of dermatology patients, decreases travel and outpatient clinic visits, and provides an avenue for ongoing support and education for primary care physicians. While difficulties exist, overcoming obstacles to the use of pediatric teledermatology and reimbursement for such services could improve access to expert pediatric dermatologic care.     

Teledermatology: a review

Teledermatology holds great potential for revolutionizing the delivery of dermatology services, providing equitable service to remote areas and allowing primary care physicians to refer patients to dermatology centres of excellence at a distance. However, before its routine application as a service tool, its reliability, accuracy and cost-effectiveness need to be verified by rigorous evaluation. Teledermatology can be applied in one of two ways: it may be conducted in real-time, utilizing videoconferencing equipment, or by store-and-forward methods, when transmitted digital images or photographs are submitted with a clinical history. While there is a considerable range of reported accuracy and reliability, evidence suggests that teledermatology will become increasingly utilized and incorporated into more conventional dermatology service delivery systems. Studies to date have generally found that real-time dermatology is likely to allow greater clinical information to be obtained from the patient. This may result in fewer patients requiring conventional consultations, but it is generally more time-consuming and costly to the health service provider. It is often favoured by the patient because of the instantaneous nature of the diagnosis and management regimen for the condition, and it has educational value to the primary care physician. Store-and-forward systems of teledermatology often give high levels of diagnostic accuracy, and are cheaper and more convenient for the health care provider, but lack the immediacy of patient contact with the dermatologist, and involve a delay in obtaining the diagnosis and advice on management. It is increasingly likely that teledermatology will prove to be a significant tool in the provision of dermatology services in the future. These services will probably be provided by store-and-forward digital image systems, with real-time videoconferencing being used for case conferences and education. However, much more research is needed into the outcomes and limitations of such a service and its effect on waiting lists, as well as possible cost benefits for patients, primary health care professionals and dermatology departments.     

Patient satisfaction with teledermatology is related to perceived quality of life

BACKGROUND: There is a lack of good data about patient satisfaction with teledermatology and about its potential interaction with quality-of-life factors. OBJECTIVES: To assess the association between perceived skin-related quality of life and patient satisfaction with a nurse-led teledermatology service. METHODS: In a mobile nurse-led teledermatology clinic located in four inner city general practices in Manchester, the teledermatology service used digital cameras to capture and store images of skin conditions for remote diagnosis by dermatologists. One hundred and twenty-three adult patients, non-urgent dermatology referrals from primary care, completed the Dermatology Life Quality Index (DLQI) and a 15-item patient satisfaction questionnaire. RESULTS: In common with other studies of patient satisfaction, subjects reported highly favourable views of 'hotel' aspects of the service (93%) and found it 'convenient' (86%). However, 40% of patients would have preferred to have had a conventional face-to-face consultation with a dermatologist, and 17% felt unable to speak freely about their condition. Patient satisfaction with the service was related to quality of life. Patients reporting lower quality of life as measured by the DLQI were more likely to prefer a face-to-face encounter with a dermatologist (r = 0.216, P < 0.05), and to evince anxiety about being photographed (r = 0.223, P < 0.05). CONCLUSIONS: Patient acceptance and satisfaction with telemedicine services is complicated by patients' subjective health status. Telehealthcare providers need to recognize that patients with poor quality of life may want and benefit from face-to-face interaction with expert clinicians.     

Preferences for aspects of a dermatology consultation

BACKGROUND: General practitioners with special interests (GPSIs) are increasingly being used to provide dermatology services in the U.K. Little is known about U.K. dermatology patient attitudes to proposed variations in secondary care service delivery or the values they attach to aspects of the care they receive. OBJECTIVES: To quantify preferences for different attributes of care within dermatology secondary care services. METHODS: Attributes of care that are important to dermatology patients were derived using in-depth qualitative interviews with 19 patients at different points in the care pathway. A discrete choice experiment using 'best-worst scaling' was sent by post to 119 patients referred to secondary care dermatology services and suitable for GPSI care who had agreed to participate in research. RESULTS: Four attributes were derived from the qualitative work: waiting, expertise, thorough care and convenience. For the discrete choice experiment, 99 patients returned questionnaires, 93 of which contained sufficient data for analysis. All attributes were found to be quantitatively important. The attribute of greatest importance was expertise of the doctor, while waiting time was of least importance. Respondents were willing to wait longer than the current 3 months maximum to receive care that was thorough, 2.1 months to see a team led by an expert and 1.3 months to attend a consultation that is easy to get to. CONCLUSIONS: Although the need to reduce outpatient waiting times is a key policy driver behind the expansion of GPSI services, this does not appear to be the most important issue for patients. The thoroughness with which the consultation is provided and the expertise of the clinician seen are higher priorities.     

Teledermatology: an intraobserver diagnostic correlation study,part I

Many studies have been published recently on the effectiveness of teledermatology as a diagnostic tool; however, much of the data comes from live 2-way video teleconferencing consultations and very little comes from more readily available "store and forward" consultations. Moreover, most published studies compare the diagnoses of 2 different dermatologists (interobserver comparison). Given the lack of data on baseline interdermatologist diagnostic variability, the interpretation of currently available diagnostic correlation data is somewhat difficult. The objective of this study is to measure the degree of diagnostic concordance between a dermatologist seeing a patient via a teledermatology consult system and the same dermatologist seeing the same patient face-to-face in a dermatology clinic at a tertiary medical center. A random sample of 404 patients was selected from patients who had routine appointments at our dermatology clinic.     

Dermatology in Botswana: The American Academy of Dermatology's Resident International Grant

In 2008, the American Academy of Dermatology began sponsoring North American dermatology residents to travel to Botswana in sub-Saharan Africa and spend 4 to 6 weeks working with the Botswana-UPenn Partnership, the Baylor International Pediatrics AIDS Initiative, Princess Marina Hospital, and surrounding smaller district hospitals. During their time in Botswana, the residents staff the busy outpatient dermatology clinic and see adult and pediatric inpatients at Princess Marina Hospital in Gaborone, the capital city. The residents also travel to 4 rural hospitals to provide clinical services to patient and education to local health care providers. The program goals include providing direct care to the people of Botswana, capacity-building through dermatologic education for local clinicians, and educating the residents about delivering dermatologic care in resource-limited and culturally diverse settings and using teledermatology consulting services. Since the start of the program, more than 1500 patients have been seen, and 35 residents would have completed the program by the end of 2010.     

Teledermatology

Teledermatology is becoming an increasingly common means of delivering dermatologic healthcare worldwide and will almost certainly play a greater role in the future. The type of technology used distinguishes the 2 modes of teledermatology consultation. The store and forward technique uses still digital images generated by a digital camera. Consultations of this type are considered asynchronous since the images are obtained, sent, and reviewed at different times. In contrast, real-time interactive consultations are synchronous. Patients and clinicians interact in real-time through an audio-video communication link. Each modality has its advantages and disadvantages, and studies appear in the literature that assess both technologies. Although diagnostic reliability (precision) assessments for teledermatology are subject to limitations, existing information indicates that both store and forward and real-time interactive technology result in reliable diagnostic outcomes when compared with clinic-based evaluations. Less information regarding diagnostic accuracy is available; however, one evaluation that used store and forward technology found comparable diagnostic accuracy between teledermatology consultations and clinic-based examinations. Currently, little information is available regarding cost effectiveness and patient outcomes. Existing evidence, while inconclusive, suggests that teledermatology may be more costly than traditional clinic-based care, especially when using real-time interactive technology. Teledermatology has been shown to have utility as a triage mechanism for determining the urgency or need for a clinic-based consultation. Overall, patients appear to accept teledermatology and are satisfied with it as a means of obtaining healthcare. Clinicians have also generally reported positive experiences with teledermatology. Future studies that focus on cost effectiveness, patient outcomes, and patient and clinician satisfaction will help further define the potential of teledermatology as a means of dermatologic healthcare delivery.     

Changing paradigms of dermatology practice in developing nations in the shadow of COVID‐19: Lessons learnt from the pandemic

At present, routine dermatology practices stay mostly disrupted worldwide owing to the ongoing COVID‐19 pandemic. However, dermatology services need to be resumed in future and dermatologists especially in developing countries face a mammoth task of devising plans to tackle the upcoming surge of patients while still maintaining the precautions to avoid risk of infection to health care workers and our patients. Teledermatology practice is a viable alternative and there is need of starting functioning teledermatology centers at primary health care centers and training health care workers in telemedicine. Several steps like increasing the working hours of outpatient clinics, posting dermatologists and health staffs in shifts, encouraging online registration and payment, providing time slots to patients should be taken to prevent overcrowding at outpatient departments in hospitals of developing countries like India where the usual patient turnover during summers maybe around 600 to 800 per day. Once diagnosed by the dermatologist, a subsequent meticulous use of teledermatology can limit the number of follow‐up visits. To avoid student gatherings, the undergraduate and postgraduate teaching schedule should be replaced by online or virtual teaching in form of webinars and video conferencing. Above all, intense upgradation of health care infrastructure, recruitment, training of new health care staffs on mass level and huge investment in health care sector is required in all the developing countries.     

Teledermatology: an update

Dermatology is perhaps the most visual specialty in medicine, making it ideally suited for modern telemedicine techniques, as has been shown in a number of recent studies investigating feasibility and reliability of teledermatology. It has generally demonstrated high levels of concordance in diagnosis and management plans compared with face-to-face consultations. Teledermatology also has been used for various purposes, including triage, diagnostic and management services, and second-opinion services for primary care practitioners. It has been set up in a number of ways: (1) direct referral for primary care using images and clinical history sent to secondary care dermatology services for second opinion and for triage referrals and (2) facilitating community-based clinics led by nurses or general practitioners. Moreover, in the last years new fields in teledermatology have grown up. Teledermoscopy is a promising area for melanoma screening as well as for the diagnosis and management of equivocal pigmented skin lesions. The feasibility of mobile teledermatology and mobile teledermoscopy recently has been proven, and these new facilities have the potential to become an easy applicable tool for everyone and may open the door for a new flexible triage system for detection of skin cancer in general and melanoma in particular. The implementation of virtual slide systems for teledermatopathology has allowed avoiding the limitations imposed by conventional microphotography. Finally, web consultations in dermatology are a rather new tool that became available in the last years and teledermatologic services through the Internet offer many possibilities, including continuing medical education, on-line atlases and databases, and specific web application suited for teledermatology (ie, www.telederm.org).     

Better, sooner, more convenient: a successful teledermoscopy service

Background/Objectives: A virtual lesion clinic (VLC) using store‐and‐forward teledermoscopy was introduced to reduce waiting times and improve access for skin lesion assessment by dermatologists. We aimed to review the efficiency and patient acceptance of a new community‐based teledermoscopy service by comparing it to hospital‐based face‐to‐face (FTF) skin lesion clinics. Methods: A prospective study compared patient flow through a community‐based VLC and a tertiary hospital FTF dermatology clinic. Surveys were sent to patients and their referring doctors after attendance. Waiting times, diagnosis, outcomes, financial costs, patient acceptability and convenience were compared. Results: A total of 300 patients were assessed; 200 were seen in the VLC and 100 in the conventional FTF clinic. Of the 200 patients seen in the VLC, 88% did not require a subsequent FTF clinic assessment to establish the diagnosis. Mean waiting times for first assessment were reduced by two thirds (from 114 days to 39 days) in those seen by the VLC compared to FTF. Financial analysis demonstrated cost savings of 14%. Surveyed patients were highly satisfied and confident in the VLC service. Conclusions: A community‐based teledermoscopy service may allow improved management of outpatient referrals while providing a better, quicker and more convenient service. It may also provide cost savings, as teledermoscopy assessment can be cheaper than traditional assessment.     

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.     

Teledermatology on the Faroe Islands

The use of teledermatology as an adjunct to conventional clinical dermatology on the Faroe Islands is described. The service is based on a nurse-led dermatological clinic, and teledermatology is combined with specialist visits for more complex diagnosis or procedures.     

Position paper: Telemedicine in occupational dermatology – current status and perspectives

Teledermatology is the use of telecommunication technologies to exchange medical information for diagnosis, consultation, treatment and teaching in dermatology. While its use has been evaluated in a wide range of dermatological diagnoses, only few studies exist on its validity, diagnostic precision, feasibility, and cost‐effectiveness in occupational dermatology. However, these studies show a considerable potential for diagnosis, prevention, treatment support and follow‐up of patients with occupational skin diseases. Asynchronous (store and forward; SAF) or synchronous dermatology teleconsults could assist occupational medicine specialists not only in occupational preventive care, but also in the context of skin cancer screening in outdoor workers. Thus, teledermatology might contribute to earlier prevention and notification of occupational skin diseases. Modern smartphone apps with artificial intelligence technologies may also facilitate self‐monitoring in employees working in high‐risk jobs.     

Teledermatology in the UK: lessons in service innovation

BACKGROUND: Teledermatology has the potential to revolutionize the delivery of dermatology services by facilitating access to specialist services at a distance. In the U.K. over the previous decade there have been numerous attempts at introducing and using teledermatology; however, the development of teledermatology as routine service provision remains limited. OBJECTIVES: To identify factors that promote successful use of teledermatology as a part of routine service provision. METHODS: A longitudinal qualitative study of teledermatology, drawing on data from in-depth semistructured interviews; observations of systems in practice; and public meetings. Data were analysed collectively by the research team using established qualitative analytical techniques to identify key thematic categories. The sample consisted of teledermatology services within the U.K. (n = 12) studied over 8 years (1997-2005). Individual participants (n = 68 interviews) were consultant dermatologists, researchers, teledermatology nurses, administrators, patient advocates, general practitioners and technologists. RESULTS: The analysis compared services that did or did not become part of routine healthcare practice to identify features that supported the normalization of teledermatology. Requirements for using and integrating teledermatology into practice included: political support; perceived benefit and relative commitment that outweighs effort; pragmatic approaches to proving efficacy and safety; perception of risk as being 'manageable' on the basis of professional judgement; high levels of flexibility in practice (in terms of individuals, technology and organization); and reconceptualizing professional roles. CONCLUSIONS: Successful implementation of teledermatology as a routine service requires greater understanding of and attention to the interplay between social and technical aspects of teledermatology, and how this is accommodated both by healthcare professionals and the organizations in which they work.     

Retrospective chart review of patient socioeconomic status and language preference associated with live video telehealth in a pediatric dermatology practice

Pediatric teledermatology rapidly expanded with the COVID-19 pandemic, and the impacts of this expansion on patients' access to care have not yet been entirely defined. In this retrospective study of 3027 patients in an academic pediatric dermatology practice, patients who identified as having a primary language other than English were less likely to access pediatric dermatology care during the COVID lockdown. This study did not identify a significant or meaningful difference in age, geography, socioeconomic status, ethnicity, or race between patients who were offered pediatric dermatology care that was either in-person or via synchronous telehealth. These findings are overall reassuring that there were not major disparities in telehealth utilization during the COVID shelter-in-place mandate, although highlight the need for institutions to ensure systems are in place to enhance telehealth access for patients with non-English primary language.     

Pilot study of store and forward teledermatology services in Perth, Western Australia

In remote areas, telemedicine services can improve the quality of access to specialist medical care and dermatology is well suited to the use of this technology. There is no published work on teledermatology services in Australia. Our purpose was to investigate the reliability of dermatological diagnoses obtained using a store and forward telemedicine system, which is being developed to offer specialist consultative services to patients in remote areas of Western Australia. We report on a small prospective non-randomized pilot study conducted at Royal Perth Hospital, Western Australia which compared diagnoses reached following telemedicine consultations with diagnoses reached following traditional face-to-face consultations. In 25 out of 50 consultations, identical diagnoses were reached. In the remaining five cases, the preferred diagnosis and first differential diagnosis were reversed in order of preference. We feel this system is sufficiently promising to trial more extensively in the field.     

Comparison of skin biopsy triage decisions in 49 patients with pigmented lesions and skin neoplasms: store-and-forward teledermatology vs face-to-face dermatology

OBJECTIVE: To determine the relative efficacy of store-and-forward teledermatology vs face-to-face dermatology consultations in triage decisions about the need for a biopsy of neoplastic skin changes. DESIGN: Prospective study of consecutive patients judged by an internist to require dermatologic consultation for a skin growth. SETTING: Private primary care and dermatology practices and an academic dermatology practice. PATIENTS: Patients requiring dermatology consultation for evaluation of skin growths. Patients were seen by a single primary care physician between July 10, 1998, and August 4, 2000. INTERVENTION: Digital photographs of skin growths were obtained by the primary care physician and evaluated by a teledermatologist. The patient was then seen face-to-face by a dermatologist. A biopsy was performed if either dermatologist favored biopsy. MAIN OUTCOME MEASURES: Decisions to perform a biopsy. Agreement between the dermatologists was assessed. RESULTS: Of the 49 patients with evaluable photographs, the face-to-face dermatologist and teledermatologist recommended a biopsy for the same 26 patients, yielding a sensitivity of the teledermatologist of 1.00 (95% confidence interval [CI], 0.87-1.00) and a specificity of 1.00 (95% CI, 0.85-1.00). The agreement between the dermatologists (kappa) was 1.00 (95% CI, 0.72-1.00). CONCLUSION: Store-and-forward teledermatology may provide an accurate and cost-effective method of determining whether skin growths in patients presenting to primary care physicians should undergo biopsy.     

A UK-wide survey looking at teaching and trainee confidence in teledermatology: a vital gap in a COVID-19-induced era of rapid digital transformation?

Teledermatology has had an explosive impact on the provision of dermatology services in recent times, and even more so with the unprecedented situation created by the COVID-19 pandemic. Although teledermatology is not presently a feature of the Joint Royal Colleges of Physicians Training Board (JRCPTB) curriculum for dermatology training, this is due to change imminently. Specialty trainees need training in this area to be able to confidently and competently meet the demands of the changing face of dermatology services. We surveyed dermatology registrars in training across the UK, prior to the outbreak of COVID-19, to ascertain the teledermatology teaching available and trainee confidence in this area. Our survey found that only 15% of respondents felt slightly confident in their ability to deal with teledermatology referrals and almost all (96%) felt more teaching was needed.
