Store-and-Forward Teledermatology for Assessing Skin Cancer in 2023: Literature Review

Background: The role of teledermatology for skin lesion assessment has been a recent development, particularly, since the COVID-19 pandemic has impacted the ability to assess patients in person. The growing number of studies relating to this area reflects the evolving interest. Objective: This literature review aims to analyze the available research on store-and-forward teledermatology for skin lesion assessment. Methods: MEDLINE was searched for papers from January 2010 to November 2021. Papers were searched for assessment of time management, effectiveness, and image quality. Results: The reported effectiveness of store-and-forward teledermatology for skin lesion assessment produces heterogeneous results likely due to significant procedure variations. Most studies show high accuracy and diagnostic concordance of teledermatology compared to in-person dermatologist assessment and histopathology. This is improved through the use of teledermoscopy. Most literature shows that teledermatology reduces time to advice and definitive treatment compared to outpatient clinic assessment. Conclusions: Overall, teledermatology offers a comparable standard of effectiveness to in-person assessment. It can save significant time in expediting advice and management. Image quality and inclusion of dermoscopy have a considerable bearing on the overall effectiveness. © Leah Kirsten Jones, Amanda Oakley.

The rise of AI in telehealth

Since its introduction in 1955, artificial intelligence (AI) has continued its growth and expansion across all industries and societal sectors. It took the COVID-19 pandemic for AI and its subsets to take the center stage in medicine and health care. AI is a broad discipline and encompasses machine learning (ML), deep learning (DL), and other techniques. Advancements in AI enabled, facilitated, and accelerated the expansion of telehealth. Telehealth describes the wide array of digital information and communication technologies and systems that allow the delivery of health and health-related services. There are three distinct subtypes of telehealth: synchronous, asynchronous, and remote (tele) monitoring. The overarching goal of telehealth is to break down barriers in delivery of high value care by overcoming challenges resulting from time or location constraints. The end goal is not to replace in-person care, rather to commoditize and democratize high quality, high value care. On the other hand, there remain significant limitations and pitfalls, particularly regulatory and technological. Examples include best practice guidelines on the adaptation of standards regulating data exchange, expansion of reimbursement and importantly ethical challenges. The latter include critical issues such as data privacy, security, and governance, AI-introduced bias, the black box nature of some AI/ML algorithms and the impact of AI technologies/algorithms on health disparities and inequities. Disparities in access to and use of tele-health were already known but highlighted during the COVID-19 pandemic. Recognition of this hurdle led to the emerging and rapidly growing field of digital determinants of health, which comprise factors like digital literacy, access to AI/technology, and community infrastructure like access to WiFi/broadband internet. © 2023 Elsevier Inc.

Evolving teledermatology policy and reimbursement landscape in the United States.

Background: Policymakers and payers are reevaluating the temporary telehealth flexibilities granted during the COVID-19 public health emergency, which will shape future teledermatology utilization. Objective: To summarize the recently expanded telehealth flexibilities in the United States, projected changes, and corresponding implications for dermatologists. Methods: Narrative review of the literature, United States policies and regulations, and white paper reports. Results: Key telehealth flexibilities included expansion of payment parity, relaxation of originating site requirements, loosening of state licensure requirements, and HIPAA (Health Insurance Portability and Accountability Act of 1996) enforcement discretion. These changes enabled widespread accessibility and adoption of teledermatology, which enhanced high-quality and cost-effective dermatologic care. Most waivers will end 151 days following the end of the public health emergency declaration. Notably, asynchronous telehealth was not included in the reimbursement expansion. Limitations: Only policies and regulations through December 2022 are included. Conclusion: It will be important for the field of dermatology to stay abreast of the upcoming changes in telemedicine policies and reimbursement, to demonstrate teledermatology's value through evidence-based studies and to advocate for enduring policies that will promote the accessibility of teledermatology for patients.

Patient Satisfaction in Teledermatology: an Updated Review.

Purpose of Review: Teledermatology continues to gain popularity across the world. It is crucial that dermatologists understand patient experience and satisfaction to effectively incorporate this practice into patient care. This article provides an updated review of recent findings on patient satisfaction in teledermatology. Recent Findings: Over the last 2 years, there has been an increase in studies on the patient experience of live-video teledermatology, while previous studies largely focused on store-and-forward teledermatology. This reflects the expansion of live-video teledermatology since the COVID-19 pandemic. Patients are generally very satisfied with both store-and-forward and live-video teledermatology, valuing its accessibility, quality of care, and patient-provider relationship. Decreased patient satisfaction is linked to technical difficulties, privacy concerns, lack of procedure availability, and thorough physical exams. However, teledermatology experiences are not equal across demographic groups. Access to technical support, digital literacy, age, social economic status, and type of dermatological conditions have all been found to affect patient experience. Summary: Studies show high levels of patient satisfaction in teledermatology but limitations exist. Future efforts to improve teledermatology experiences will require reducing barriers among demographics, improving patient education, investment in technology, and collaboration among all parties involved.

Store-and-Forward Images in Teledermatology: Narrative Literature Review.

Background: Store-and-forward (SAF) teledermatology uses electronically stored information, including patient photographs and demographic information, for clinical decision-making asynchronous to the patient encounter. The integration of SAF teledermatology into clinical practice has been increasing in recent years, especially during the COVID-19 pandemic. Despite this growth, data regarding the outcomes of SAF teledermatology are limited. A key distinction among current literature involves comparing the quality and utility of images obtained by patients and trained clinicians, as these metrics may vary by the clinical expertise of the photographer. Objective: This narrative literature review aimed to characterize the outcomes of SAF teledermatology through the lens of patient- versus clinician-initiated photography and highlight important future directions for and challenges of the field. Methods: A literature search of peer-reviewed research was performed between February and April 2021. Key search terms included patient-initiated, patient-submitted, clinician-initiated, clinician-submitted, store-and-forward, asynchronous, remote, image, photograph, and teledermatology. Only studies published after 2001 in English were included. In total, 47 studies were identified from the PubMed electronic database and Google Scholar after omitting duplicate articles. Results: Image quality and diagnostic concordance are generally lower and more variable with patient-submitted images, which may impact their decision-making utility. SAF teledermatology can improve the efficiency of and access to care when photographs are taken by either clinicians or patients. The clinical outcomes of clinician-submitted images are comparable to those of in-person visits in the few studies that have investigated these outcomes. Coinciding with the onset of the COVID-19 pandemic, asynchronous teledermatology helped minimize unnecessary in-person visits in the outpatient setting, as many uncomplicated conditions could be adequately managed remotely via images captured by patients and referring clinicians. For the inpatient setting, SAF teledermatology minimized unnecessary contact during dermatology consultations, although current studies are limited by the heterogeneity of their outcomes. Conclusions: In general, photographs taken by trained clinicians are higher quality and have better and more relevant diagnostic and clinical outcomes. SAF teledermatology helped clinicians avoid unnecessary physical contact with patients in the outpatient and inpatient settings during the COVID-19 pandemic. Asynchronous teledermatology will likely play a greater role in the future as SAF images become integrated into synchronous teledermatology workflows. However, the obstacles summarized in this review should be addressed before its widespread implementation into clinical practice.

Using Implementation Science to Understand Teledermatology Implementation Early in the COVID-19 Pandemic: Cross-sectional Study.

Background: Implementation science has been recognized for its potential to improve the integration of evidence-based practices into routine dermatologic care. The COVID-19 pandemic has resulted in rapid teledermatology implementation worldwide. Although several studies have highlighted patient and care provider satisfaction with teledermatology during the COVID-19 pandemic, less is known about the implementation process. Objective: Our goal was to use validated tools from implementation science to develop a deeper understanding of the implementation of teledermatology during the COVID-19 pandemic. Our primary aims were to describe (1) the acceptability and feasibility of the implementation of teledermatology and (2) organizational readiness for the implementation of teledermatology during the COVID-19 pandemic. We also sought to offer an example of how implementation science can be used in dermatologic research. Methods: An anonymous, web-based survey was distributed to Association of Professors of Dermatology members. It focused on (1) the acceptability, feasibility, and appropriateness of teledermatology and (2) organizational readiness for implementing teledermatology. It incorporated subscales from the Organizational Readiness to Change Assessment-a validated measure of organizational characteristics that predict implementation success. Results: Of the 518 dermatologists emailed, 35 (7%) responded, and all implemented or scaled up teledermatology during the pandemic. Of the 11 care providers with the highest level of organizational readiness, 11 (100%) said that they plan to continue using teledermatology after the pandemic. Most respondents agreed or strongly agreed that they had sufficient training (24/35, 69%), financial resources (20/35, 57%), and facilities (20/35, 57%). However, of the 35 respondents, only 15 (43%) agreed or strongly agreed that they had adequate staffing support. Most respondents considered the most acceptable teledermatology modality to be synchronous audio and video visits with supplemental stored digital photos (23/35, 66%) and considered the least acceptable modality to be telephone visits without stored digital photos (6/35, 17%). Overall, most respondents thought that the implementation of synchronous audio and video with stored digital photos (31/35, 89%) and telephone visits with stored digital photos (31/35, 89%) were the most feasible. When asked about types of visits that were acceptable for synchronous video/audio visits (with stored digital photos), 18 of the 31 respondents (58%) said "new patients," 27 (87%) said "existing patients," 19 (61%) said "medication monitoring," 3 (10%) said "total body skin exams," and 22 (71%) said "lesions of concern." Conclusions: This study serves as an introduction to how implementation science research methods can be used to understand the implementation of novel technologies in dermatology. Our work builds upon prior studies by further characterizing the acceptability and feasibility of different teledermatology modalities. Our study may suggest initial insights on how dermatology practices and health care systems can support dermatologists in successfully incorporating teledermatology after the pandemic.

Emergency Use and Efficacy of an Asynchronous Teledermatology System as a Novel Tool for Early Diagnosis of Skin Cancer during the First Wave of COVID-19 Pandemic.

BACKGROUND: After the outbreak of the corona virus disease-19 (COVID-19) pandemic, teledermatology was implemented in the Hungarian public healthcare system for the first time. Our objective was to assess aggregated diagnostic agreements and to determine the effectiveness of an asynchronous teledermatology system for skin cancer screening. METHODS: This retrospective single-center study included cases submitted for teledermatology consultation during the first wave of the COVID-19 pandemic. Follow-up of the patients was performed to collect the results of any subsequent personal examination. RESULTS: 749 patients with 779 lesions were involved. 15 malignant melanomas (9.9%), 78 basal cell carcinomas (51.3%), 21 squamous cell carcinomas (13.8%), 7 other malignancies (4.6%) and 31 actinic keratoses (20.4%) were confirmed. 87 malignancies were diagnosed in the high-urgency group (42.2%), 49 malignancies in the moderate-urgency group (21.6%) and 16 malignancies in the low-urgency group (4.6%) (p < 0.0001). Agreement of malignancies was substantial for primary (86.3%; κ = 0.647) and aggregated diagnoses (85.3%; κ = 0.644). Agreement of total lesions was also substantial for primary (81.2%; κ = 0.769) and aggregated diagnoses (87.9%; κ = 0.754). CONCLUSIONS: Our findings showed that asynchronous teledermatology using a mobile phone application served as an accurate skin cancer screening system during the first wave of the COVID-19 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.

Teledermatology before, during, and after the COVID-19 pandemic. / Teledermatología en tiempos de pandemia: El antes, el durante y el después.

The use and acceptance of teledermatology increased more in the last 2 months of the recent lockdown owing to coronavirus disease 2019 than in the preceding 20 years. This sudden popularity -even among the greatest skeptics- was driven by the need to offer solutions to patients in both public and private settings who suddenly found themselves unable to access in-person dermatological care. Even departments already offering an asynchronous, store-and-forward teledermatology service were obliged to create new systems to support direct interaction between specialists and patients (the direct-to-consumer model). This article suggests some practical ways to implement TD safely and to expedite and optimize teleconsultations; these ideas are not just applicable to a pandemic situation.

The Impact of COVID-19 on Teledermatology: A Review.

The accelerated implementation and use of teledermatology during the coronavirus disease 2019 pandemic has met with successes and challenges. This review explores how telemedicine was used in dermatology before the pandemic, the regulatory adaptions made in response to the pandemic, and the effectiveness of the rapid implementation of teledermatology during the coronavirus disease 2019 pandemic, and, finally, how teledermatology has expanded in response to the pandemic. This review examines lessons learned and how teledermatology's reliance on digital technologies might paradoxically exacerbate health care disparities, and finally, considers the future outlook.

Direct-to-Patient Teledermatology During COVID-19 Lockdown in a Health District in Madrid, Spain: The EVIDE-19 Pilot Study. / Estudio piloto de la teledermatología directa durante el estado de alarma por la pandemia COVID-19 en un área sanitaria de Madrid (Estudio EVIDE-19).

BACKGROUND: Dermatologic care was halted because of the coronavirus disease 2019 pandemic, prompting us to study the usefulness of direct-to-patient teledermatology via a mobile application. We aimed to evaluate the service as a tool for avoiding face-to-face consultations, describe the main conditions diagnosed, and assess levels of patient and physician satisfaction. MATERIAL AND METHOD: Prospective descriptive study of new patients who met the inclusion criteria. Descriptive statistics for all variables were analyzed with SPSS. RESULTS: Of the 1,497 patients who agreed to participate in the study, 25% (n=374) sent an image to a consultant dermatologist through the mobile application. Sixty-four patients (17%) were discharged directly and referred to primary care for follow-up. A face-to-face consultation was avoided for at least 3 months in 85% of patients (n=318); 87.1% (n=325) received a diagnosis and the dermatologist's level of confidence in this diagnosis was 7 or higher in 77.5% of cases (n=290). The quality of the images sent was considered sufficient in 52.1% of cases. Patients rated their satisfaction with a score of 4.5 out of 5. Eleven of the 16 dermatologists rated their satisfaction as good overall. The most common conditions were inflammatory and melanocytic lesions. The main diagnoses were nevi, acne, and eczema. DISCUSSION: Direct-to-patient store-and-forward teledermatology is an effective means of evaluating new patients. Both clinicians and patients expressed high levels of satisfaction with the service. Systems enabling the addition of digital images to patient records are necessary to ensure the efficiency of teledermatology.

Teledentistry applications for mitigating risk and balancing the clinical schedule.

The upheaval of providers and their patients has led to many changes in the way people live and work. In addition to the changes in Personal Protective Equipment (PPE) guidelines, there has been evidence of rapid adoption of telehealth services. In April of 2020, the American Dental Association's Health Policy Institute released a report stating that 1 in 4 dentists nationally were utilizing teledentistry to perform limited evaluations. Many of these dentists are new to teledentistry, and unfortunately, direct-to-patient consultations yield limited clinical outcomes. The more traditional methods of using teledentistry have been extending the reach of dental care for over a decade, using an allied team member such as a dental hygienist or expanded-function dental assistant. As dentistry adapts to this new environment, it is important that there be adequate awareness of the diverse uses of teledentistry to meet the needs of the population. This brief, outlines one dental clinic's attempt at providing a broad use of teledentistry.

Definitions, survey methods, and findings of patient satisfaction studies in teledermatology: a systematic review.

Remote consultations likely will grow in importance if the COVID-19 pandemic continues. This review analyzes which methods of teledermatology patients prefer by categorizing how recent studies have defined satisfaction, conducted surveys and concluded patients respond to the different modalities of teledermatology. Using PubMed and Cochrane databases, we reviewed studies from April 5th, 2010 to April 5th, 2020 that included the search terms patient satisfaction and teledermatology. All studies that included patient satisfaction as an outcome were included, but studies not published in English were excluded. We examined domains of satisfaction, survey method, study characteristics (including patient population, country, age, study design and evidence score), findings and statistical comparisons. We thoroughly reviewed 23 studies. Definitions of satisfaction varied, but all concluded patients were satisfied with the live-interactive and store-and-forward modalities. The studies reveal that store-and-forward is appropriate for clinicians with established patients who require regular follow-up. Verified areas of care include treatment of chronic conditions, topical skin cancer therapy, wound monitoring, and post-procedural follow-up. Only four studies conducted statistical analyses. One of those studies compared patient preference for each modality of teledermatology with face-to-face dermatology. While this study reported high satisfaction with each mode of teledermatology, patients still preferred face-to-face. Favorable responses to remote diagnostic capabilities suggest that these offerings improve preference for teledermatology. With only one study evaluating preference between each modality and face-to-face dermatology, more studies should address the discrepancy. Surveys that cover all domains of satisfaction may improve assessments and identify where gaps in preference exist.

Inpatient teledermatology during the COVID-19 pandemic.

Coronavirus Disease 2019 (COVID-19) represents a global health crisis in which personal protective equipment has become increasingly limited. Dermatologists are poised to use technology, such as teledermatology, to innovate existing workflows and optimize dermatologic care. The state of Ohio has emerged as a leader in the United States with its response to the COVID-19 crisis. In response to the COVID-19 crisis, we developed a simple algorithm and strict guidelines to prioritize telemedicine specifically for inpatient dermatology consults. This algorithm was quickly accepted by our hospital leadership and adopted by other inpatient consultative services. In this Viewpoint, we share our experience with early adoption of teledermatology in the inpatient consultative setting in light of the COVID-19 crisis. We also highlight the limitations, ethical considerations, and areas for future research with respect to the implementation of teledermatology.
