Teledermatology in the United States: An Update in a Dynamic Era

Optimizing Dermatological Care Triage in a Safety-Net Hospital: Retrospective Analysis of Diagnoses and In-Person Referrals

OBJECTIVES

Teledermatology is a cost-effective and efficient approach to delivering care and is particularly beneficial for patients with limited access to specialized services. Considering the rapid expansion of telehealth, it is crucial to focus on optimization. The purpose of our study was to evaluate the triaging of dermatologic care in an electronic consultation (e-consultation) service in a safety-net hospital.

METHODS

This was a 2-year retrospective review of a dermatology asynchronous store-and-forward e-consultation service.

RESULTS

A total of 1425 patients completed 1502 e-consultation. Of these e-consultations, 46% of the patients had Medicaid and 44% were Black or African American. The top three diagnoses were dermatitis unspecified, neoplasm of uncertain behavior, and acne/rosacea. Most (68%) were managed via e-consultation and did not require an in-person appointment. Children and adolescents were more likely to require an in-person appointment (74%) compared with adults (30%, P < 0.0001). Patients with a chief complaint of hair loss or skin lesion were more likely to require in-person evaluation (58% and 41%, respectively) compared with rash (24%) and acne (18%) (P < 0.0001). There was no difference found in recommendations for in-person evaluation based on race, non-English-language preference, or insurance status.

CONCLUSIONS

E-consultation services seem well suited for certain concerns, and underserved populations can be evaluated by teledermatology.

Teledermatology Use in the Elderly: An Analysis of Teledermatology Utilization Patterns Across Age Groups

Introduction: Telehealth is an emerging tool used to improve access to care for patients. However, there is a lack of literature comparing the use of telehealth between patients of different age groups in dermatology. Our study aims to determine whether differences exist in teledermatology usage between elderly and younger dermatology patients. Methods: We conducted a cross-sectional study using the 2020-2021 Medical Expenditure Panel Survey. Our study population included a weighted total of 150,290,604 patients: Of these, 16.35% were young adults (18-44 years old), 26.32% were midlife adults (45-64 years old), and 57.33% were elderly (65+ years old). Results: Our results showed that elderly patients had significantly lower rates of teledermatology use than young adults (odds ratio [OR] = 0.184, (confidence interval [CI]: 0.081-0.421)), p < 0.000) and midlife adults (OR = 0.193, [CI: 0.091-0.406], p < 0.000). Midlife adults had similar rates of telehealth use when compared with young adults (OR = 1.044, [CI: 0.508-2.145], p = 0.907). Our results were adjusted for sex, race, ethnicity, insurance type, education level, income, travel time, and medical comorbidities. Discussion: We found that elderly patients seeking dermatology care are less likely to use telehealth than younger dermatology patients. Our results demonstrate that barriers to telehealth use for the elderly may be more prohibitive than expected. Understanding these differences in teledermatology use is essential for improving teledermatology delivery across all age groups.

Pediatric dermatology eConsultation: Insights to reduce barriers to utilization and increase access to care

Provider-to-provider outpatient pediatric dermatology eConsultation services increase access to care, but barriers exist that may prevent eConsult implementation and survival. We deployed cross-sectional surveys to referring pediatric primary care physicians and consulting pediatric dermatologists participating in our eConsult program to identify barriers to utilization and sustainability. Our data suggest that eConsultation increases access to care and offers iterative educational opportunities for primary care providers, which may ultimately reduce office referrals for common outpatient skin issues. Sustainability of eConsult services requires simple order templates, clear representative photos, concise submission reports, and provider reimbursement.

Pre-trained multimodal large language model enhances dermatological diagnosis using SkinGPT-4

Large language models (LLMs) are seen to have tremendous potential in advancing medical diagnosis recently, particularly in dermatological diagnosis, which is a very important task as skin and subcutaneous diseases rank high among the leading contributors to the global burden of nonfatal diseases. Here we present SkinGPT-4, which is an interactive dermatology diagnostic system based on multimodal large language models. We have aligned a pre-trained vision transformer with an LLM named Llama-2-13b-chat by collecting an extensive collection of skin disease images (comprising 52,929 publicly available and proprietary images) along with clinical concepts and doctors' notes, and designing a two-step training strategy. We have quantitatively evaluated SkinGPT-4 on 150 real-life cases with board-certified dermatologists. With SkinGPT-4, users could upload their own skin photos for diagnosis, and the system could autonomously evaluate the images, identify the characteristics and categories of the skin conditions, perform in-depth analysis, and provide interactive treatment recommendations.

The Teledermatology Experience: Cost Savings and Image Quality Control

Introduction: Teledermatology adoption continues to increase, in part, spurred by the COVID-19 pandemic. This study analyzes the utility and cost savings of a store-and-forward teledermatology consultative system within the Veterans Health Administration (VA). Methods: Retrospective cohort of 4,493 patients across 14 remote sites in Tennessee and Kentucky from May 2017 through August 2019. The study measured the agreement between the teledermatology diagnoses and follow-up face-to-face clinic evaluations as well as the cost effectiveness of the teledermatology program over the study period. Results: Fifty-four percent of patients were recommended for face-to-face appointment for biopsy or further evaluation. Most patients, 80.5% received their face-to-face care by a VA dermatologist. There was a high level of concordance between teledermatologist and clinic dermatologist for pre-malignant and malignant cutaneous conditions. Veterans were seen faster at a VA clinic compared with a community dermatology site. Image quality improved as photographers incorporated teledermatologist feedback. From a cost perspective, teledermatology saved the VA system $1,076,000 in community care costs. Discussion: Teledermatology is a useful diagnostic tool within the VA system providing Veteran care at a cost savings.

The Past, the Present and the Future of Teledermatology: A Narrative Review

Teledermatology may be defined as the application of telemedicine to dermatology. According to published data, teledermatology is more widespread in Europe and North America, probably where resources for health care are greater than in other areas of the world. Indeed, teledermatology requires advanced technology to be efficient, as high image quality is necessary to allow the dermatologist to make correct diagnoses. Thanks to the recent advances in this field, teledermatology is become routinary in daily clinical practice. However, its use has been improved over time, overcoming several challenges. The aim of this narrative review is to retrace the almost 30-year history of teledermatology, to address the new challenges posed by advancing technologies such as artificial intelligence and the implications it may have on healthcare.

Serial Dependence in Dermatological Judgments

Serial Dependence is a ubiquitous visual phenomenon in which sequentially viewed images appear more similar than they actually are, thus facilitating an efficient and stable perceptual experience in human observers. Although serial dependence is adaptive and beneficial in the naturally autocorrelated visual world, a smoothing perceptual experience, it might turn maladaptive in artificial circumstances, such as medical image perception tasks, where visual stimuli are randomly sequenced. Here, we analyzed 758,139 skin cancer diagnostic records from an online app, and we quantified the semantic similarity between sequential dermatology images using a computer vision model as well as human raters. We then tested whether serial dependence in perception occurs in dermatological judgments as a function of image similarity. We found significant serial dependence in perceptual discrimination judgments of lesion malignancy. Moreover, the serial dependence was tuned to the similarity in the images, and it decayed over time. The results indicate that relatively realistic store-and-forward dermatology judgments may be biased by serial dependence. These findings help in understanding one potential source of systematic bias and errors in medical image perception tasks and hint at useful approaches that could alleviate the errors due to serial dependence.

Impact of the COVID-19 Pandemic on the Delivery of Dermatological Care

Purpose of Review

We review several important changes affecting dermatology during the COVID-19 pandemic, beginning in March 2020. Specifically, we focus on the impact of the COVID-19 pandemic on physician trends in employment, delivery of care via teledermatology, and burnout, resilience, and wellness.

Recent Findings

More physicians are now employed by corporate entities than prior to the pandemic. Teledermatology can be utilized effectively and integrated into current care models; however, the continued use of teledermatology will largely depend on financial compensation. The COVID-19 pandemic was a source of burnout for all physicians, including dermatologists, and impacted how many people view their work.

Summary

The COVID-19 pandemic pushed physicians to change their employment, required them to implement telehealth rapidly, and forced them to re-evaluate their priorities. Prior to the pandemic, more physicians transitioned into employed positions as compared to physician-owned practices. Multiple reasons for consolidation exist, but the trend accelerated during the COVID-19 pandemic for all medical specialties. Similarly, teledermatology was utilized prior to the pandemic, but its use exploded in the early days of the COVID-19 pandemic and continues to this day. The future of teledermatology though depends primarily on insurance reimbursement for these visits as well as both patient and physician preferences for continued usage. Lastly, wellness became a major focus in medicine as the pandemic took a significant toll on physicians, including dermatologists.

Teledermatology in Rural, Underserved, and Isolated Environments: A Review

Purpose of Review

Recent Findings

Summary

Access to pediatric dermatology

PURPOSE OF REVIEW

To identify factors that impact accessibility to pediatric dermatology and review healthcare delivery models that improve access and address these barriers.

RECENT FINDINGS

Up to one-third of pediatric primary care visits include a skin-related problem, yet pediatric dermatology subspecialist services are highly inaccessible. Workforce shortages and geographic, sociocultural, and economic barriers perpetuate inaccessibility. Teledermatology expands care, particularly to underserved or geographically remote communities, and reduces healthcare-related costs. Federal legislation to support telehealth services with adequate reimbursement for providers with parity between live, video, and phone visits will dictate the continued feasibility of virtual visits. Innovative care delivery models, such as language-based clinics, multidisciplinary teleconferencing, or embedded dermatology services within primary care are other promising alternatives.

SUMMARY

Despite efforts to expand access, dermatology still ranks among the most underserved pediatric subspecialties. Improving access requires a multipronged approach. Efforts to expand exposure and mentorship within pediatric dermatology, diversify the workforce and clinical curriculum, recruit and retain clinicians in geographically underserved areas, and collaborate with policymakers to ensure adequate reimbursement for teledermatology services are necessary.

Shaping the Future of Teledermatology: A Literature Review of Patient and Provider Satisfaction with Synchronous Teledermatology during the COVID-19 Pandemic

Following the onset of the COVID-19 pandemic, widespread adoption of synchronous teledermatology (e.g., live videoconferencing) has increased patient and provider familiarity. To our knowledge, no teledermatology reviews have exclusively characterized patient and provider satisfaction with synchronous models of teledermatology. This study determines the quantitative evaluation of patient and provider satisfaction through a literature review of synchronous teledermatology studies conducted during the COVID-19 pandemic. A review of the literature was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines within the PubMed database. Search terms included, but were not limited to, teledermatology, patient satisfaction, and provider satisfaction. Studies were evaluated for quality of evidence based on guidelines described by the Oxford Center for Evidence-based Medicine. Fifteen studies satisfied the inclusion criteria which described the satisfaction of 7871 patients and 146 providers with synchronous teledermatology during the COVID-19 pandemic. Patients and providers were overall satisfied with access measures, the patient- provider relationship and the ability of synchronous teledermatology to meet patient needs. Limitations of the virtual physical exam and image or video quality were two consistent limiting factors in patient and provider experience, respectively. Patients and providers perceive that synchronous teledermatology meets the needs of the patient. Patients perceived satisfactory patient-provider relationship through synchronous teledermatology. Practices can identify best applications and educate patients on expectations of the virtual examination in order to enhance utilization and sustainability of synchronous teledermatology beyond the pandemic.

Synchronous and asynchronous teledermatology: A narrative review of strengths and limitations

The policy changes prompted by the COVID-19 pandemic caused synchronous models (primarily video visits) to supplant asynchronous models (store-and-forward or shared digital photographs) as the default and predominant modality of teledermatology care. Here, we call attention to the unique strengths and limitations of these models in terms of clinical utility, accessibility, and cost-effectiveness. Strengths of synchronous visits include direct physician-patient interaction and current reimbursement parity; limitations include variable video image quality, technological difficulties, and accessibility barriers. Strengths of asynchronous visits include greater convenience, especially for clinicians, and potential for image quality superior to video; limitations include less direct physician-patient communication, barriers to follow-up, and limited reimbursement. Both synchronous and asynchronous models have been shown to be cost-effective. Teledermatology is positioned to play a prominent role in patient care post-pandemic. Moving forward, dermatologists are challenged to optimize teledermatology use in order to improve outcomes, efficiency, and workflows to meet diverse patient needs. Future directions will depend on sustainable reimbursement of both teledermatology formats by government and private payers.

Access, charge and quality of tele-dermatology e-consults in China: A standardized patients study

OBJECTIVE

Direct-to-consumer telemedicine is rapidly changing the way that patients seek medical care. This study provided the first report on access, cost and quality of text- and image-based tele-dermatology e-consults, in China.

METHODS

We adopted the Standardized Patients approach to evaluate the services of tele-dermatology e-consults in two metropolitan cities, that is, Beijing and Hangzhou, in China. We measured quality from four dimensions: service process, diagnosis accuracy, prescription and treatment comprehensiveness, based on China's national clinical guidelines. We performed logistic regressions to investigate factors that were associated with high-quality care.

RESULTS

For 114 physicians eligible for inclusion, we succeeded in 87 (76%) validated visits. The median waiting time was 100 minutes (IQR 19-243 minutes) and the median length of consultation was 636 minutes (about 10 hours, IQR 188-1528 minutes). Per visit costs varied from $0 to $38, with a median of $8 (IQR 4-9). Among all, 15% of visits showed high quality in service process, 84% arrived in the correct diagnosis, 24% provided high-quality prescriptions and 71% provided comprehensive treatment. Providing images was associated with high quality in service process (OR 7.22, 95% CI 1.49-34.88). Visits in metropolitan Beijing and on non-work days had better prescription quality than that in metropolitan Hangzhou (OR 6.05, 95% CI 1.75-20.95) and that on workdays (OR 3.75, 95%CI 1.27-11.04), respectively.

CONCLUSIONS

Tele-dermatology e-consults seem to be easy to access and less expensive in China. However, great efforts are warranted to ensure that service processes and prescriptions adhere to clinical guidelines.

The Utilization and Impact of Live Interactive and Store-and-Forward Teledermatology in a Veterans Affairs Medical Center During the COVID-19 Pandemic

Introduction: Teledermatology has emerged as a promising method of continuing dermatologic care during the coronavirus 2019 (COVID-19) pandemic, including in the Department of Veterans Affairs (VA). Analysis of the utilization and impact of teledermatology within the San Francisco Veterans Affairs Health Care System (SFVAHCS) may elucidate the ways that teledermatology programs can continue to be optimized. Methods: We conducted a retrospective analysis of live interactive encounters, Veterans Affairs Video Connect (VVC), store-and-forward telehealth (SFT), and face-to-face (FTF) consultations, performed within the SFVAHCS from March 2020 to December 2020. To assess utilization, we analyzed numbers of encounters throughout 2020. To assess impact, we analyzed primary diagnoses for each encounter and rates of recommendations for medications and lesion biopsies. Additionally, we assessed diagnostic accuracy associated with each teledermatology type by measuring concordance between teledermatologists' clinical diagnoses and histopathological diagnoses. Results: Two thousand two hundred fifty FTF, 347 VVC, and 470 SFT encounters were conducted from March to December 2020. More female patients utilized VVC, and patients who utilized VVC were younger than SFT and FTF users (p < 0.01). SFT was utilized more by patients from rural areas (p < 0.01). Diagnoses addressed were significantly different between VVC and SFT. A majority of VVC encounters involved referrals for inflammatory conditions; primary diagnoses associated with SFT consultations were most frequently neoplasms. Comparison of VVC and SFT outcomes showed that more VVC visits resulted in a medication recommendation, while more SFT consultations resulted in a biopsy recommendation. Conclusions: Teledermatology contributed to meeting patient needs throughout 2020 and created an impact on clinical management. Patient characteristics, diagnoses, and type of impact associated with encounters varied between SFT and VVC. This analysis provides insight into teledermatology utilization within the VA system and can contribute to efforts to improve the quality of teledermatology care for veterans.

COVID-19-The American Perspective

The Coronavirus Disease 2019 (COVID-19) pandemic is a recent, ongoing global infection that has affected more than 200 countries worldwide, with the United States having the highest per capita infection rate. Professional organizations, accrediting bodies, licensing boards, and government agencies have been important partners to academic institutions and the health care system during this pandemic response. We review the American perspective of the impact of COVID-19 on dermatology.

Teledermatology Consults in a County Hospital Setting: Retrospective Analysis

Collapse

Evaluation of electronic consults for outpatient pediatric patients with dermatologic complaints

BACKGROUND

Although dermatologic complaints are frequently encountered by pediatricians, access to pediatric dermatologists remains limited. Teledermatology has been proposed to expand access to dermatologic care for children. We report our experience with a physician-to-physician store-and-forward teledermatology service (eConsults), focusing on patient and consult characteristics and their relationship with teledermatologist confidence and follow-up recommendations as well as clinical outcomes.

METHODS

We reviewed electronic health records of all pediatric patients referred through eConsults at the Massachusetts General Hospital from 1/13/2020 to 7/17/2020. We assessed pediatrician and parental receptiveness with a confidential survey.

RESULTS

A total of 302 referrals (median patient age 4.6 years (IQR 0.6-12); 54% female) and 310 cases were completed in 1.8 days on average (SD = 1.2). Teledermatologists rated their confidence as definite and moderate in 51.3% and 39.4% cases, respectively. Teledermatologists felt comfortable managing rashes remotely, but patients with alopecia, pigmented and vascular lesions, and warts frequently required formal dermatology evaluation. Among patients seen subsequently, full concordance was seen for 70.1% of diagnoses and 74.4% of management recommendations. All responding pediatricians were satisfied with the service, and 97.5% felt that the parents were receptive to it.

CONCLUSIONS

Our study supports the growing evidence that store-and-forward teledermatology can quickly and effectively provide the access to pediatric dermatologic care and is well received by pediatricians and parents. To maximize cost-effectiveness of store-and-forward teledermatology, dermatologists should work with referring providers to improve the quality of submitted photographs and patient history as well as advise in-person referrals for cases likely to require further follow-up.

The policy dimensions, regulatory landscape, and market characteristics of teledermatology in the United States

The COVID-19 pandemic has spurred healthcare systems across the world to rapidly redesign their models of care delivery. As such, this pandemic has accelerated the adoption of teledermatology in the United States. However, it remains unknown whether this momentum will be maintained after the pandemic. The future of teledermatology in the United States will be significantly influenced by a complex set of policy, legal, and regulatory frameworks. An understanding of these frameworks will help dermatologists more effectively adopt and implement teledermatology platforms. In this article, we review the current state of teledermatology in the United States, including policy dimensions, the regulatory landscape, market characteristics, and future directions.

International Teledermatology Review

Purpose of Review

The use of teledermatology has been evolving slowly for the delivery of health care to remote and underserved populations. Improving technology and the recent COVID-19 pandemic have hastened its use internationally.

Recent Findings

Some barriers to the use of teledermatology have fallen considerably in the last year.

Summary

Teledermatology use has increased significantly in recent years in both government-sponsored and private health care systems and individual practices. There are no recognized international practice guidelines and variable use within countries. Many barriers remain to increasing the use of teledermatology.

Retrospective analysis of 450 emergency department dermatology consultations: An analysis of in-person and teledermatology consultations from 2015 to 2019

INTRODUCTION

Dermatologic complaints are a common reason for emergency department visits.

METHODS

Retrospective chart review from 1 January 2015 to 31 December 2019. Patients in the Mayo Clinic Emergency Department receiving dermatology consultation were included.

RESULTS

Dermatitis (24.7%, n = 113), infection (20.4%, n = 93), and drug reaction (10.3%, n = 47) accounted for the majority of diagnoses. Emergency department providers often provide no diagnosis (38%) or a differential diagnosis (22%), and dermatology consultation frequently alters diagnosis (46%) and treatment (83%). Patients receiving in-person consultations are admitted more frequently than those receiving teledermatology consultations (40% vs. 16%, p < 0.001). Primary diagnostic concordance with subsequent dermatology evaluation is high for in-person (94%) and teledermatology (88%) consultations.

DISCUSSION

This is the largest study of emergency department dermatology consultations in the United States and the first to compare in-person and teledermatology emergency department consultation utilization in clinical practice. These modalities are utilized in a complementary fashion at our institution, with severe dermatologic diagnoses seen in-person. The valuable role of emergency department dermatologists is highlighted by frequent changes to diagnosis and treatment plans that result from dermatology consultation. Furthermore, our data suggest that teledermatology is an effective modality with the potential to expand access to dermatologic expertise in the emergency department setting.

Teledermatology in 2020: past, present and future perspectives

Born in 1995, teledermatology (TD) turns 25 years old today. Since then, TD evolved according to patients and physicians needs. The present review aimed to summarize all the efforts and experiences carried out in the field of TD and its subspecialties, the evolution and the future perspectives. A literature search was conducted in PubMed and Google Scholar. The state of the art of the "tele-dermo research" included TD and clinical trials, TD/TDS web platforms, TDS and artificial intelligence studies. Finally, the future perspective of TD/TDS in the era of social distancing was discussed. Using TD in specific situations adds several benefits including time-effectiveness of intervention and reduction in the waiting time for the first visit, reduced travel-costs, reduced sanitary costs, equalization of access from patient to specialistic consult. The communication technologies devices currently available can adequately support the growing needs of tele-assistance. A main limit is the current lack of a common clear European regulation for practicing TD, encompassing privacy issues and data management. The pandemic lockdown of 2020 has highlighted the importance of performing TD for all those patient, elderly and/or fragile, where the alternative would be no care at all. Many efforts are needed to develop efficient workflows and TD programs to facilitate the interplay among the different TD actors, along with practice guidelines or position statements.

Teledermatology Addressing Disparities in Health Care Access: a Review

Purpose of Review

Dermatologists have been at the forefront of researching telemedicine to expand access to care. The current COVID-19 pandemic has prompted even greater expansion and implementation of teledermatology. This review discusses the research examining the potential impact of teledermatology addressing disparities in care.

Recent Findings

Teledermatology appears to increase access to dermatology given expanded means to deliver care. Specifically, recent studies have found increased access among Medicaid-insured, resource-poor urban and rural, and elderly populations. Teledermatology implementation also facilitates education among providers at different levels of training. Still, as some patients have inconsistent access to the required technology, increased reliance on telemedicine may also potentially increase disparities for some populations.

Summary

Teledermatology may serve to reduce disparities in health care access in many underserved and marginalized communities. Future research should continue to study implementation, especially given the expansion during the COVID-19 pandemic. Ultimately, teledermatology may play an important role in ensuring equitable care access for all.

Prospective Implementation of a Consultative Store-and-Forward Teledermatology Model at a Single Urban Academic Health System with Real Cost Data Subanalysis

Background: Teledermatology may increase access to care but has not been widely implemented due, in part, to lack of insurance coverage and reimbursement. We assessed the impact of implementing a consultative store-and-forward teledermatology model on access to care, medical cost, and utilization. Materials and Methods: Prospective implementation of teledermatology occurred at five University of Pennsylvania Health System primary care practices from June 27, 2016, to May 25, 2017. Primary outcomes included time to case completion, proportion of patients completing in-person dermatology visits, and total outpatient costs. Medical and pharmacy claims data were used for utilization and cost subanalysis. Results: The study included 167 patients and 1,962 controls with a 6-month follow-up. Median time to definitive dermatologist response was 0.19 days (interquartile range [IQR]: 0.03-2.92) for intervention and 83.60 days (IQR: 19.74-159.73) for controls. In medical claims subanalysis, no significant differences in mean outpatient costs ($3,366 vs. $2,232, p = 0.1356) or total medical costs ($3,535 vs. $2,654, p = 0.2899) were detected. Conclusions: Implementation of teledermatology improved access to care, and within this small sample, remained comparable in terms of cost and utilization. Thus, these data suggest teledermatology may improve access without increasing utilization or cost.

Strategies to maximize clinical efficiency while maintaining patient safety during the COVID-19 pandemic: an interview-based study from private practice dermatologists

BACKGROUND

Many dermatologists have experienced significant changes to their practices due to the COVID-19 pandemic.

OBJECTIVE

It is vital to recognize how the pandemic has affected dermatology practices and identify methods to maximize clinical efficiency while maintaining patient safety.

METHODS

Private practice dermatologists in metropolitan areas were interviewed regarding various issues, including patient volume, types of visits or procedures being performed, screening for COVID-19, and operational modifications.

RESULTS

On average, there was a 65.2% decrease in patient volume during the initial surge of the COVID-19 outbreak, which was improved to a 15.5% decrease in July 2020. Despite this reduction in patient volume, the proportion of acute dermatologic issues, biopsies performed, and skin cancer concerns were all increased compared to pre-COVID. All of the dermatologists reported notable changes in regards to scheduling, staff, operations, and workplaces.

LIMITATIONS

Interview participants were limited to metropolitan dermatologists mainly within the California region.

CONCLUSION

Improving patient communication, implementing protocols to facilitate social distancing, and utilizing teledermatology were reported to be essential to optimizing efficiency and safety. As the COVID-19 pandemic continues to evolve, it is important that dermatologists identify specific ways to practice efficiently and effectively, while mitigating the spread of the virus.

Teledermatology: current indications and considerations for future use

Telemedicine is one of the most consequential technologies in modern healthcare. In certain situations, it allows for the delivery of care with high quality and minimal difficulty. This is particularly true in dermatology, in which many dermatological conditions can be treated remotely. The burden on dermatology patients has been greatly reduced for certain pathologies due to telemedicine. Health care providers also achieve improved job satisfaction following the convenience of meeting their patients. This paper details select dermatological conditions, and subsequently divides them into those treatable by telemedicine appointments, and those requiring face to face appointments.

Technology-enabled activation of skin cancer screening for hematopoietic cell transplantation survivors and their primary care providers (TEACH)

BACKGROUND

Hematopoietic cell transplantation (HCT) is a curative option for a growing number of patients with hematologic diseases and malignancies. However, HCT-related factors, such as total body irradiation used for conditioning, graft-versus-host disease, and prolonged exposure to immunosuppressive therapy, result in very high risk for melanoma and non-melanoma skin cancer (NMSC). In fact, skin cancer is the most common subsequent neoplasm in HCT survivors, tending to develop at a time when survivors' follow-up care has largely transitioned to the primary care setting. The goal of this study is to increase skin cancer screening rates among HCT survivors through patient-directed activation alone or in combination with physician-directed activation. The proposed intervention will identify facilitators of and barriers to risk-based screening in this population and help reduce the burden of cancer-related morbidity after HCT.

METHODS/DESIGN

720 HCT survivors will be enrolled in this 12-month randomized controlled trial. This study uses a comparative effectiveness design comparing (1) patient activation and education (PAE, N = 360) including text messaging and print materials to encourage and motivate skin examinations; (2) PAE plus primary care physician activation (PAE + Phys, N = 360) adding print materials for the physician on the HCT survivors' increased risk of skin cancer and importance of conducting a full-body skin exam. Patients on the PAE + Phys arm will be further randomized 1:1 to the teledermoscopy (PAE + Phys+TD) adding physician receipt of a portable dermatoscope to upload images of suspect lesions for review by the study dermatologist and an online course with descriptions of dermoscopic images for skin cancers.

DISCUSSION

When completed, this study will provide much-needed information regarding strategies to improve skin cancer detection in other high-risk (e.g. radiation-exposed) cancer survivor populations, and to facilitate screening and management of other late effects (e.g. cardiovascular, endocrine) in HCT survivors.

A deep learning system for differential diagnosis of skin diseases

Skin conditions affect 1.9 billion people. Because of a shortage of dermatologists, most cases are seen instead by general practitioners with lower diagnostic accuracy. We present a deep learning system (DLS) to provide a differential diagnosis of skin conditions using 16,114 de-identified cases (photographs and clinical data) from a teledermatology practice serving 17 sites. The DLS distinguishes between 26 common skin conditions, representing 80% of cases seen in primary care, while also providing a secondary prediction covering 419 skin conditions. On 963 validation cases, where a rotating panel of three board-certified dermatologists defined the reference standard, the DLS was non-inferior to six other dermatologists and superior to six primary care physicians (PCPs) and six nurse practitioners (NPs) (top-1 accuracy: 0.66 DLS, 0.63 dermatologists, 0.44 PCPs and 0.40 NPs). These results highlight the potential of the DLS to assist general practitioners in diagnosing skin conditions.

Implementing Teledermatology for Rural Veterans: An Evaluation Using the RE-AIM Framework

Introduction: Few systematic evaluations of implementing teledermatology programs in large health care systems exist. We conducted a longitudinal evaluation of a U.S. Department of Veterans Affairs (VA) initiative to expand asynchronous consultative teledermatology services for rural veterans. Methods: The reach, effectiveness, adoption, implementation, and maintenance framework guided the evaluation, which included analysis of quantitative VA administrative data as well as an online survey completed by participating facilities. The first 2 years of the program were compared with the year before the start of funding. Results: Sixteen hub facilities expanded teledermatology's reach over the 2-year period, increasing the number of referral spoke sites, unique patients served, and teledermatology encounters. Effectiveness was reflected as teledermatology constituted an increasing fraction of dermatology activity and served more remotely located patients. Adoption through defined stages of implementation progressed as facilities engaged in a variety of strategies to enhance teledermatology implementation, and facilitators and barriers were identified. Program maintenance was assessed by Program Sustainability Index scores, which reflected the importance of executive support, and ongoing concerns about staffing and longitudinal funding. Discussion: Enabling hubs to create solutions that best fit their needs and culture likely increased reach and effectiveness. Important facilitators included organizational leadership and encouraging communication between stakeholders before and during the intervention. Conclusions: A systematic analysis of teledermatology implementation to serve rural sites in VA documented a high degree of implementation and sustainability as well as areas for improvement.

Implementing and Optimizing Inpatient Access to Dermatology Consultations via Telemedicine: An Experiential Study

Background/Introduction: In-house dermatology consultation services for hospitalized patients are not universally available in acute care hospitals. We encountered an unanticipated access gap for in-person dermatology consultations in our tertiary care hospital that routinely cares for complex high acuity patients with multiple comorbidities. To bridge this gap in specialist expertise in a timely manner, we expeditiously designed and implemented a telemedicine-supported inpatient dermatology consultation service. Methods: We conducted a retrospective review of 155 teledermatology consultations conducted between November 2017 and March 2019 as well as periodic prospective multidisciplinary process improvement meetings to optimize service-associated process maps and workflows. Results: Teledermatology consultations changed the working diagnosis of the primary team in 52.3% of cases and most commonly recommended medical management (61.9% of cases). In total 100% of patients accepted telemedicine support and rated their experience as positive. The first three periodic process improvement meetings led to significant improvements in teledermatology-related process maps and workflows. Discussion: Diagnostic concordance rates between the primary team and the teledermatologist were similar to those reported in the literature for in-person dermatology consultations. Important process improvements include establishing central responsibility of preparing and overseeing the consultation process, mandating the presence of a primary team representative during consultation and patient chart review by the teledermatologist before teleconsultation. Conclusion: Inpatient teledermatology consultation services can be instituted timely and continuously improved to reliably and effectively bridge access gaps, improve diagnostic accuracy and differentiate therapeutic approaches while maintaining patient satisfaction.

A review of literature supporting the development of practice guidelines for teledermatology in Australia

Despite the potential of teledermatology to increase access to dermatology services and improve patient care, it is not widely practised in Australia. In an effort to increase uptake of teledermatology, Australian-specific practice guidelines for teledermatology are being developed by the Australasian College of Dermatologist. This paper reports finding from literature reviews that were undertaken to inform the development of these guidelines. Results cover the following sections: Modalities of teledermatology; Patient selection and consent; Imaging; Quality and safety; Privacy and security; Communication; and Documentation and retention. The document educates providers about the benefits and limitations of telehealth while articulating how to enhance patient care and reduce risk when practicing teledermatology.

Clinical effectiveness and cost-effectiveness of teledermatology: Where are we now, and what are the barriers to adoption?

There has been rapid growth in teledermatology over the past decade, and teledermatology services are increasingly being used to support patient care across a variety of care settings. Teledermatology has the potential to increase access to high-quality dermatologic care while maintaining clinical efficacy and cost-effectiveness. Recent expansions in telemedicine reimbursement from the Centers for Medicare & Medicaid Services (CMS) ensure that teledermatology will play an increasingly prominent role in patient care. Therefore, it is important that dermatologists be well informed of both the promises of teledermatology and the potential practice challenges a continuously evolving mode of care delivery brings. In this article, we will review the evidence on the clinical and cost-effectiveness of teledermatology and we will discuss system-level and practice-level barriers to successful teledermatology implementation as well as potential implications for dermatologists.

Use of a telehealth follow-up system to facilitate treatment and discharge of emergency department patients with severe cellulitis

INTRODUCTION

Novel long-acting lipoglycopeptide antibiotics allow for the treatment and discharge of selected emergency department (ED) patients with cellulitis who require intravenous antibiotics. Telehealth systems have shown success in remote management of dermatologic conditions; we implemented a telehealth follow-up program for patients diagnosed with cellulitis in the ED, treated with single-dose dalbavancin, and discharged.

METHODS

This was a prospective, multi-center observational study. Patients were included based on clinical criteria and ability to complete follow-up using a smartphone and enroll in an online care portal. We examined the rate of successful telehealth follow-up at 24- and 72-hour intervals from discharge. We also examined the ED return rate within 14 days, reviewed any visits to determine cause of return, and for admission.

RESULTS

55 patients were enrolled. 54/55 patients completed at least one telehealth follow up encounter (98.2%). 13 patients (23.6%) had a return ED visit within 14 days; no patients required admission for worsening cellulitis. Patient engagement in the telehealth program decreased over time; there was an approximately 11% decrease in engagement between the 24 and 72-hour follow-up call, and a 15% decrease in engagement between the 24 and 72-hour image upload. Patients over 65 had a lower rate of image upload (31%) than younger patients (80.6%).

DISCUSSION

A telehealth follow-up system for discharged emergency department patients with cellulitis demonstrated high rates of engagement. In these patients who -may have otherwise required admission for intravenous antibiotics, telehealth-facilitated outpatient management resulted in a low ED return rate and no inpatient admissions for cellulitis.

Does location matter? Geographic variations in healthcare resource use for atopic dermatitis in the United States

BACKGROUND

It is unknown which region of the U.S. offers the best and worst access to care for atopic dermatitis (AD).

METHODS

We conducted a cross-sectional study using the Medical Expenditure Panel Survey (MEPS) from 1996 to 2015 to compare healthcare resource use and cost of AD among U.S. census regions. We conducted multivariable regression analyses adjusting for clinicodemographic factors to evaluate regional differences in healthcare resource use and cost per patient per year (PPPY) in terms of ambulatory visits, ED visits, and medications directly attributable to AD.

RESULTS

An estimated total of 6,348,578 (95% CI: 5,944,553-6,752,803) AD patients (weighted) were pooled. Compared to the remainder of the country, Midwest AD patients utilized the fewest ambulatory visits (0.55 versus 0.75 visits PPPY; p = .035). The proportion of patients with ≥1 ED visits was highest in the Midwest (7.1%), followed by the South (5.4%), Northeast (4.8%), and West (1.4%). Within the Midwest AD population, those with no ambulatory visits per year utilized nearly three times more ED visits when compared with those with one or more ambulatory visits per year (0.11 versus 0.04 visits PPPY; p = .019).

CONCLUSION

Our results suggest that Midwest AD patients have differential access to outpatient care, which may be resulting in higher ED usage.

Evaluation of Barriers to Telehealth Programs and Dermatological Care for American Indian Individuals in Rural Communities

Importance

Understanding geographic and financial barriers to health care is an important step toward creating more accessible health care systems. Yet, the barriers to dermatological care access for American Indian populations in rural areas have not been studied extensively.

Objective

To evaluate the driving distances and insurance coverage for dermatological care and the current availability of teledermatological programs within the Indian Health Service (IHS) or tribal hospitals system.

Design, Setting, and Participants

This mixed-methods study was conducted from May 7, 2018, to September 1, 2018, and did not take place in any IHS or tribal health care facility in the continental United States. The study design involved a geographic analysis and a cross-sectional telephone survey with brick-and-mortar dermatology clinics (n = 27) and teledermatological programs (n = 49). Brick-and-mortar clinics were selected for their proximity to a rural IHS or tribal hospital.

Main Outcomes and Measures

Mean driving distance from rural IHS or tribal hospital to nearest dermatology clinic, number of dermatology clinics within a 35-mile or 90-mile radius of IHS or tribal hospitals, insurance and referral types accepted by dermatology clinics, and number of teledermatological programs collaborating with IHS or tribal hospitals or health centers.

Results

In total, 27 brick-and-mortar dermatology clinics and 49 teledermatological programs were identified and contacted for the survey. The median (interquartile range [IQR]) driving distance between rural IHS or tribal hospitals and the nearest dermatology clinic was 68 (30-104) miles. Of the 27 dermatology clinics in closest proximity to rural IHS or tribal hospitals (median [IQR] driving distance, 82.4 [31-114] miles), 25 (93%) responded to the survey, 6 (22%) did not accept patients with Medicaid, and 6 (22%) did not accept IHS referrals for patients without insurance. Of the 49 teledermatological programs, 45 (92%) responded and 14 (29%) were no longer active. Ten (20%) teledermatology programs were currently partnering (n = 6), previously partnered (n = 2), or were setting up services (n = 2) with an IHS or tribal site. Only 9% (n = 27) of the 303 rural IHS or facility in the continental United States reported receiving teledermatological services.

Conclusions and Relevance

Substantial geographic and insurance coverage barriers to dermatological care exist for American Indian individuals in rural communities; teledermatological innovations could represent an important step toward minimizing the disparities in dermatological care access and outcomes.

Abortion through telemedicine

PURPOSE OF REVIEW

Medical abortion offers a well tolerated and effective method to terminate early pregnancy, but remains underutilized in the United States. Over the last decade, 'telemedicine' has been studied as an option for medical abortion to improve access when patients and providers are not together. A number of studies have explored various practice models and their feasibility as an alternative to in-person service provision.

RECENT FINDINGS

A direct-to-clinic model of telemedicine medical abortion has similar efficacy with no increased risk of significant adverse events when compared with in-person abortion. A direct-to-consumer model is currently being studied in the United States. International models of direct-to-consumer medical abortion have shown promising results.

SUMMARY

The introduction of telemedicine into abortion care has been met with early success. Currently, there are limitations to the reach of telemedicine because of specific restrictions on mifepristone in the United States as well as laws that specifically prohibit telemedicine for abortion. If these barriers are removed, telemedicine can potentially increase abortion access.

A 14-year review of a UK teledermatology service: experience of over 40 000 teleconsultations

BACKGROUND

There is a paucity of published evidence of established teledermatology (TD) services in the UK. An in-house TD service using store-and-forward technology was set up at a large regional dermatology department in 2004.

AIM

To review the TD service at our centre, including teleconsultation numbers, coding of diagnoses and patient outcomes.

METHODS

Retrospective data were retrieved using the electronic patient database, from 31 July 2004 to 31 July 2018. More detailed information on patient outcomes was obtained from patient notes and histology records. A paper questionnaire was distributed to 100 patients to obtain patient feedback.

RESULTS

In total, 40 201 teleconsultations were made over 14 years, and 64% of cases were coded (n = 25 555), of which 77% were lesions. The most common coded lesions were benign naevus (25%), seborrhoeic keratosis (22%) and basal cell carcinoma (19%). Of the total number of cases, 50% were discharged to their general practitioner with advice, 34% were booked for surgery and 16% were booked for a face-to-face appointment. In the survey, 82% of patients surveyed felt that the service was 'good' or 'very good'. A detailed study between 1 January 2015 and 1 January 2016 showed that there were 383 patients (10%) with no diagnosis made following teleconsultation, suggesting diagnostic uncertainty. Reasons for this included lack of diagnostic features, possibility of malignancy and service factors. Within this cohort, there was 68% diagnostic concordance.

CONCLUSIONS

We have set up a successful TD service at a UK centre, which has prevented 16 282 face-to-face appointments over 14 years. Patient feedback has been very good. Review of cases with diagnostic uncertainty provides important information for service improvement and has not previously been documented.
