Cost analysis of a store-and-forward teledermatology consult system in Philadelphia

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.

Revolutionizing teledermatology: Exploring the integration of artificial intelligence, including Generative Pre-trained Transformer chatbots for artificial intelligence-driven anamnesis, diagnosis, and treatment plans

The integration of teledermatology and artificial intelligence (AI) marks a significant advancement in dermatologic care. This study examines the synergistic interplay between these two domains, highlighting their collective impact on enhancing the accuracy, accessibility, and efficiency of teledermatologic services. Teledermatology expands dermatologic care to remote and underserved areas, and AI technologies show considerable potential in analyzing dermatologic images and performing various tasks involved in teledermatology consultations. Such integration facilitates rapid, precise diagnoses, personalized treatment plans, and data-driven insights. Our explorative study involved designing a GPT-based chatbot named "Dr. DermBot" and exploring its performance in a teledermatologic consultation process. The design phase focused on the chatbot's ability to conduct consultations autonomously. The subsequent testing phase assessed its performance against the backdrop of current teledermatologic practices, exploring the potential of AI and chatbots to simulate and potentially enhance teledermatologic health care. Our study demonstrates the promising future of combining teledermatology with AI. It also brings to light ethical and legal concerns, including the protection of patient data privacy and adherence to regulatory standards. The union of teledermatology and AI not only aims to enhance the precision of teledermatologic diagnoses but also broadens the accessibility of dermatologic services to previously underserved populations, benefiting patients, health care providers, and the overall health care system.

Does the Diagnostic Accuracy and Rates of Face-to-Face Visits Occurring Shortly after an Asynchronized Teledermatology Consultation Justify Its Implementation? An 18-Month Cohort Study

INTRODUCTION

In 2019, Maccabi Health Services (MHS) rolled out the store-and-forward "Dermadetect" teledermatology consultation (TC) application. Study goal was to analyze MHS records of TCs (August 2019-February 2021) for the rate and reasons for face-to-face consultations (FTFC) occurring shortly after a TC with emphasis on FTFCs resulting in a different diagnosis for the same indication.

METHODS

The records of FTFCs held up shortly after TCs were reviewed and classified into cases marked as unsuited for teledermatology, cases in which the indication differed, and cases with the same indication, which were analyzed for concordance of diagnoses.

RESULTS

Dermadetect was used by 12,815 MHS beneficiaries. In 30% of cases, following FTFC occurred within the subsequent 5 months, and 901 of them occurred in the subsequent 2 weeks and were analyzed. Thirty percent were not suited for teledermatology, 15% were held for a different indication, and 55% occurred for the same indication. The diagnosis concordance between the TC and recurrent FTFC for the same indication was 97.4%, with full concordance at 68.1% and partial concordance at 29.3%. Overall, 13 patients (1.4%) of the 901 patients using the application only once had a subsequent FTFC within 2 weeks and received a different diagnosis than the one given in the TC.

CONCLUSIONS

When considering the implementation of store-and-forward TC's, a 30% rate of following FTFC's during the next 5 months should be considered when planning the reimbursement model. Diagnosis discordance may be disregarded due to its low rates.

Store-and-forward (asynchronous) doctor-to-dermatologist non-skin cancer specific teledermatology services in Australia: A scoping review

Store-and-forward teledermatology (SAFT) has become increasingly popular as a means to increase access to specialist care and address healthcare disparities such as those experienced by rural communities. A contemporary systematic overview of the Australian SAFT services and outcomes for all dermatological conditions is missing. This scoping review provides an overview of Australian SAFT models. Twelve studies were identified through web databases, grey literature sites and reference lists of eligible articles. Eligibility criteria included studies evaluating doctor-to-dermatologist Australian SAFT services provided to Australians for all skin conditions but excluded the studies that solely focused on skin cancers. Data on study design, setting, population, SAFT model, referral characteristics, patient, and general practitioner perspectives, diagnostic concordance, and measured outcomes such as follow up, investigation and waiting time were extracted. Quality of the included studies was assessed using CASP tools. Synthesis reveals that SAFT can be used for patients with any dermatological condition, provides more accurate diagnostics compared to cases without dermatologist input, may reduce waiting times for dermatological expertise, and users generally had positive experiences with SAFT. Although results are positive, this review reveals the heterogenous nature of the literature on SAFT in Australia and a need to establish a uniform approach to assessing the outcomes and impacts of such services.

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

Purpose of Review

Recent Findings

Summary

Partnering with a senior living community to optimise teledermatology via full body skin screening during the COVID-19 pandemic: A pilot programme

BACKGROUND

Elderly patients in senior communities faced high barriers to care during the COVID-19 pandemic, including increased vulnerability to COVID-19, long quarantines for clinic visits, and difficulties with telemedicine adoption.

OBJECTIVE

To pilot a new model of dermatologic care to overcome barriers for senior living communities during the COVID-19 pandemic and assess patient satisfaction.

METHODS

From 16 November 2020 to 9 July 2021, this quality improvement programme combined in-residence full body imaging with real-time outlier lesion identification and virtual teledermatology. Residents from the Sequoias Portola Valley Senior Living Retirement Community (Portola Valley, California) voluntarily enroled in the Stanford Skin Scan Programme. Non-physician clinical staff with a recent negative COVID-19 test travelled on-site to obtain in-residence full body photographs using a mobile app-based system on an iPad called SkinIO that leverages deep learning to analyse patient images and suggest suspicious, outlier lesions for dermoscopic photos. A single dermatologist reviewed photographs with the patient and provided recommendations via a video visit. Objective measures included follow-up course and number of skin cancers detected. Subjective findings were obtained through patient experience surveys.

RESULTS

Twenty-seven individuals participated, three skin cancers were identified, with 11 individuals scheduled for a follow up in-person visit and four individuals starting home treatment. Overall, 88% of patients were satisfied with the Skin Scan programme, with 77% likely to recommend the programme to others. 92% of patients agreed that the Skin Scan photographs were representative of their skin. In the context of the COVID-19 pandemic, 100% of patients felt the process was safer or comparable to an in-person visit. Despite overall appreciation for the programme, 31% of patients reported that they would prefer to see dermatologist in-person after the pandemic.

CONCLUSIONS

This programme offers a framework for how a hybrid skin scan programme may provide high utility for individuals with barriers to accessing in-person clinics.

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.

A Pilot Study to Assess the Reliability of Digital Image-Based PASI Scores Across Patient Skin Tones and Provider Training Levels

Introduction

The ability to perform psoriasis skin assessments remotely through digital image-based psoriasis area and severity index (DIB-PASI) would be a valuable tool for psoriasis clinical trials. An ideal teledermatological assessment would be robust across patients of diverse skin tones as well as across assessors of varying experience levels. In this pilot study, we evaluated the reliability of face-to-face (FTF) versus DIB-PASI scores determined by trained clinical assessors with a spectrum of experience and with patients of different skin tones.

Methods

Fourteen subjects of varying skin tones with moderate-to-severe plaque psoriasis were treated with adalimumab. In-person PASI assessments and digital photography were performed in the clinic at weeks 0, 12, and 24. Photographs were reviewed by four independent assessors to derive a digital image-based PASI score. The concordance of face-to-face PASI (FTF-PASI) and DIB-PASI were analyzed across patient and assessor factors.

Results

Overall concordance between FTF-PASI and DIB-PASI was high (ICC 0.82, p < 0.0001), with good agreement across individual assessors. When analyzed by PASI score component or body region, digital assessors also demonstrated good agreement with the FTF assessor. Similarly, DIB-PASI showed high concordance with FTF-PASI for patients with light skin tones and patients with medium-to-dark skin tones, and across clinical training levels.

Conclusion

Overall, PASI scores derived from digital images showed good agreement with those determined in person. Importantly, these remote assessments were reliable for both light and medium-to-dark skin tones, and robust to training level of the assessor. The findings from this pilot study lay the foundation for expanding teledermatology-based clinical trials for patients with psoriasis and enabling accurate, remote monitoring of disease severity and therapy response.

Teledermatology versus Face-to-Face Dermatology: An Analysis of Cost-Effectiveness from Eight Studies from Europe and the United States

(1) Background: The aim of this systematic review was to compare the cost-effectiveness of two follow-up methods (face-to-face and telemedicine) used in dermatology in the last ten years. (2) Methods: A search for articles that included economic analyses was conducted in August 2021 in the databases PubMed, Medline, Scielo and Scopus using the following keywords: "Cost-Benefit Analysis", "Dermatology", "Telemedicine", "Primary Health Care", as well as other search terms and following the PICOS eligibility criteria. (3) Results: Three clinical trials and five observational studies were analyzed, providing information for approximately 16,539 patients (including four cost-minimization or saving analyses, three cost-effectiveness analyses, and one cost-utility analysis) in Europe and the United States. They describe the follow-up procedures in each of the cases and measure and analyze the direct and indirect costs and effectiveness. All the articles indicate that teledermatology lowers costs and proves satisfactory to both patients and professionals. (4) Conclusions: Although it has been found that follow-up via teledermatology can be more efficient than traditional hospital follow-up, more work is needed to establish evaluation protocols and procedures that measure key variables more equally and demonstrate the quality of the evidence of said studies.

Teledermatologie: Fluch oder Segen?

Teledermatologische Dienste haben sich insbesondere während der COVID-19-Pandemie als Alternative zu „Echt“visiten verbreitet. Der Mangel an Dermatologen und die Möglichkeit einer präzisen Diagnose auch bei unterversorgten Regionen macht diese Alternative für alle Beteiligten besonders attraktiv. Trotzdem ist der Bedarf an Schulungen des Personals und der Anwender hoch. Ebenfalls können Implementierungs-, Instandhaltungs- und Wartungskosten der notwendigen Ausrüstung und die Heterogenität der unterschiedlichen Anbieter nachteilig für Patient und Arzt sein. In diesem Artikel werden wesentliche Vorteile und Nachteile der Teledermatologie zusammengefasst.

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.

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.

Teledermatology During COVID-19: An Updated Review

The coronavirus disease 2019 (COVID-19) pandemic has fundamentally transformed the landscape of providing dermatologic care. In an age of lockdowns and social distancing, teledermatology (TD) has emerged as a powerful tool to deliver remote care. Here, we review literature on TD use during the pandemic to evaluate the positives and negatives of TD implementation. We especially consider the reception of TD in underserved communities and the developing world as well as the ethico-legal challenges wrought by the burgeoning utilization of this new paradigm of care. The potential of TD to occupy a more prominent role in dermatologic care in a post-COVID-19 world is also discussed.

Remote Rating of Atopic Dermatitis Severity Using Photo-Based Assessments: Proof-of-Concept and Reliability Evaluation

BACKGROUND

Digital imaging of dermatological patients is a novel approach to remote assessment and has recently become more relevant since telehealth and remote decentralized clinical trials are gaining ground.

OBJECTIVE

We aimed to investigate whether photographs taken by a smartphone are of adequate quality to allow severity assessments to be made and to explore the usefulness of an established atopic dermatitis severity assessment instrument on photograph evaluation.

METHODS

During scheduled visits in a previously published study, the investigating doctor evaluated the severity of atopic dermatitis using the Scoring AD (SCORAD) index and took photographs of the most representative lesions (target lesions) with both a smartphone and a digital single-lens reflex camera (DSLR). The photographs were then assessed by 5 dermatologists using the intensity items of the SCORAD (iSCORAD), which consists of erythema, oedema/papulation, excoriations, lichenification, oozing/crusts, and dryness (scale 0-3, maximum score 18). The mean iSCORAD of the photographs was calculated and compared with in-person assessments using Pearson correlation and Bland-Altman plots. Intraclass correlation coefficients were used for interrater reliability.

RESULTS

A total of 942 photographs from 95 patients were assessed. The iSCORAD based on smartphone photographs correlated strongly with the evaluations performed in person (iSCORAD: r=0.78, P<.001; objective SCORAD: r=0.81, P<.001; and total SCORAD: r=0.78, P<.001). For iSCORAD specifically, a Bland-Altman plot showed a difference in mean score of 1.31 for in-person and remote iSCORAD. In addition, the interrater agreement between the 5 rating dermatologists was 0.93 (95% CI 0.911-0.939). A total of 170 lesions were photographed, and the difference in mean scores was 1.32, 1.13, and 1.43 between in-person and remote evaluations based on photographs taken by a DSLR camera, a smartphone without flash, and a smartphone with flash, respectively.

CONCLUSIONS

In terms of quality, remote atopic dermatitis severity assessments based on photographs are comparable to in-person assessments, and smartphone photos can be used to assess atopic dermatitis severity to a similar degree as photographs from a DSLR camera. Further, the variation in how the dermatologists in this study rated the iSCORAD based on the photographs was very low.

Inter-rater variability in patch test readings and final interpretation using store-forward teledermatology

BACKGROUND

Data regarding teledermatology for patch testing are limited.

OBJECTIVES

Compare patch test readings and final interpretation by two in-person dermatologists (IPDs) with eight teledermatologists (TDs).

METHODS

Patch tested patients had photographs taken of 70 screening series of allergens at 48 hours and second readings. Eight TDs reviewed photos and graded reactions (negative, irritant, doubtful, +, ++, +++) at 48 hours and second readings; in addition, they coded a final interpretation (allergic, indeterminant, irritant, negative) for each reaction. TDs rated overall image quality and confidence level for each patient and patch test reaction, respectively. Percentage of TD-IPD agreement based on clinical significance (success, indeterminate, and failure) was calculated. Primary outcome was agreement at the second reading.

RESULTS

Data were available for 99, 101, and 66 participants at 48 hours, second reading, and final interpretation, respectively. Pooled failure (+/++/+++ vs negative) at second reading was 13.6% (range 7.9%-20.4%). Pooled failure at 48 hours and final interpretation was 5.4% (range 2.9%-6.8%) and 24.6% (range 10.2%-36.8%), respectively. Confidence in readings was statistically correlated with quality of images and disagreement.

CONCLUSION

For patch testing, teledermatology has significant limitations including clinically significant pooled failure percentages of 13.6% for second readings and 24.6% for final interpretation.

The utility of teledermatology in the evaluation of skin lesions

INTRODUCTION

Past studies have shown mixed results about the accuracy of store-and-forward (SAF) teledermatology in the evaluation of skin lesions. The objective of this study is to determine the accuracy of SAF teledermatology in the diagnosis of skin lesions and biopsy decision compared to in-person clinical evaluation.

METHODS

Histories and photographs of skin lesions gathered at clinic visits were sent as SAF consults to teledermatologists, whose diagnoses and biopsy decisions were recorded and compared statistically to the clinic data.Results and Discussion: We enrolled 206 patients with 308 lesions in the study. The study population was composed of 50% males (n = 104), and most patients were white (n = 179, 87%) and not Hispanic/Latino (n = 167, 81%). There was good concordance for biopsy decision between the clinic dermatologist (CD) and teledermatologist (TD) (Cohen's kappa (κ) = 0.51), which did not significantly differ when melanocytic lesions were excluded (κ = 0.54). The sensitivity and specificity of teledermatology based on biopsy decision was 0.71 and 0.85, respectively. Overall concordance in first diagnosis between the CD and TD was good (κ = 0.60). While there was no difference between CD and TD in proportion of correct diagnoses compared to histopathology, two skin cancers presentations were missed by TD. Study limitations included sample size, enrolment bias and differing amounts of teledermatologist case experience. Teledermatology has good concordance in diagnosis and biopsy decision when compared to clinic dermatology. Teledermatology may be utilized in the evaluation of skin lesions to expand access to dermatologic care.

Cost Minimization Analysis of a Teledermatology Triage System in a Managed Care Setting

Importance

Teledermatology (TD) enables remote triage and management of dermatology patients. Previous analyses of TD systems have demonstrated improved access to care but an inconsistent fiscal impact.

Objective

To compare the organizationwide cost of managing newly referred dermatology patients within a TD triage system vs a conventional dermatology care model at the Zuckerberg San Francisco General Hospital and Trauma Center (hereafter referred to as the ZSFG) in California.

Design, Setting, and Participants

A retrospective cost minimization analysis was conducted of 2098 patients referred to the dermatology department at the ZSFG between June 1 and December 31, 2017.

Intervention

Implementation of the TD triage system in January 2015.

Main Outcomes and Measures

The main outcome was mean cost to the health care organization to manage newly referred dermatology patients with or without TD triage. To estimate costs, decision-tree models were constructed to characterize possible care paths with TD triage and within a conventional dermatology care model. Costs associated with primary care visits, dermatology visits, and TD visits were then applied to the decision-tree models to estimate the mean cost of managing patients following each care path for 6 months. The mean cost for each visit type incorporated personnel costs, with the mean cost per TD consultation also incorporating software implementation and maintenance costs. Finally, ZSFG patient data were applied within the models to evaluate branch probabilities, enabling calculation of mean cost per patient within each model.

Results

The analysis captured 2098 patients (1154 men [55.0%]; mean [SD] age, 53.4 [16.8] years), with 1099 (52.4%) having Medi-Cal insurance and 879 (41.9%) identifying as non-White. In the decision-tree model with TD triage, the mean (SD) cost per patient to the health care organization was $559.84 ($319.29). In the decision-tree model for conventional dermatology care, the mean (SD) cost per patient was $699.96 ($390.24). Therefore, the TD model demonstrated a statistically significant mean (SE) cost savings of $140.12 ($11.01) per patient. Given an annual dermatology referral volume of 3150 patients, the analysis estimates an annual savings of $441 378.

Conclusions and Relevance

Implementation of a TD triage system within the dermatology department at the ZSFG was associated with cost savings, suggesting that managed health care settings may experience significant cost savings from using TD to triage and manage patients.

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.

Pediatric dermatology eConsults: Reduced wait times and dermatology office visits

BACKGROUND/OBJECTIVES

Store-and-forward teledermatology provides pediatricians with specialist guidance in managing skin disease. This study evaluates wait times and face-to-face (FTF) dermatology visit avoidance associated with a pediatric dermatology eConsult program at an urban academic medical center.

METHODS

In this retrospective cohort study, electronic medical records were reviewed for patients under age 18 for whom a dermatology eConsult was completed between November 1, 2014, and December 31, 2017. Wait times for eConsult completion and initial FTF dermatology appointments were calculated and compared to average wait times for new patient dermatology office appointments from 2016 to 2017. Recommendations for FTF dermatology visits were assessed, along with FTF visit attendance and potential cost savings.

RESULTS

One hundred eighty pediatric patients with 188 unrelated skin conditions ("cases") were referred to the program. Of 188 cases, FTF dermatology visits were recommended for 60 (31.9%). Actual FTF dermatology visit avoidance was 53.7% of total cases (n = 101 for whom FTF visit was not recommended and no dermatology visit occurred within 90 days after eConsult submission). The program generated potential savings of $24 059 ($9840 out-of-pocket) in 2016 dollars. Average turnaround for eConsult completion was 1.8 calendar days (median: 1 calendar day, target: 2 business days). Average wait time to initial FTF dermatology evaluation was 37.3 calendar days (versus 54.1 days for pediatric patients referred directly to dermatology clinic between 2016 and 2017).

CONCLUSION

Pediatric dermatology eConsults reduce wait times for specialist care, triage cases for in-office evaluation, reduce need for FTF dermatology visits, and offer potential cost savings for payers and patients.

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.

Teledermatology Consultation Can Optimize Treatment of Cutaneous Disease by Nondermatologists in Under-Resourced Clinics

Background: Access to dermatologists is limited for disadvantaged patients, who may receive suboptimal dermatologic care from nonspecialists. We assessed if teledermatology could improve primary care provider (PCP)-delivered care for cutaneous disease at a clinic serving uninsured patients. Materials and Methods: Utilizing the American Academy of Dermatology's free AccessDerm program, we offered store-and-forward teledermatology to PCPs, who initiated consultations at will during clinical care independent of the study. We retrospectively analyzed all consultations from 2013 to 2017 and collected patient age/sex, teledermatologist diagnosis, time to teledermatologist reply, time to next dermatology appointment, as well as PCP- and teledermatologist-proposed care plans. Results: Retrospective analysis of 131 consults revealed a 37-h mean teledermatology response-time versus a 14-day appointment wait (p < 0.00001). Teledermatologists provided a definitive care plan without in-person evaluation for 82 (65%) of completed consults and recommended interim treatments while awaiting appointments in 15 cases, thus accelerating care plan delivery in 97 cases (76%). The triage decision rate differed among diagnostic categories; deferral to in-person evaluation was more frequent for neoplasms (p < 0.0001). When PCPs specified preconsult treatment plans, 82% differed from teledermatologist-advised management. Following teledermatologist recommendations would have changed the clinical course in 70% of cases, potentially avoiding suboptimal care, including inappropriate corticosteroids, antimicrobials, and emergency room referrals. Conclusions: We found teledermatology can effectively guide PCPs in resource-limited settings by accelerating delivery of dermatologist-recommended care plans for uninsured patients. Expanding teledermatology for PCPs in under-resourced clinics has the potential to improve treatment of cutaneous disease by nonspecialists and to mitigate suboptimal care for disadvantaged patients.

Impact of teledermatology on the accessibility and efficiency of dermatology care in an urban safety-net hospital: A pre-post analysis

BACKGROUND

Teledermatology enables dermatologists to remotely triage and evaluate dermatology patients, but previous studies have questioned whether teledermatology is clinically efficient.

OBJECTIVE

To determine whether implementation of a teledermatology system at the Zuckerberg San Francisco General Hospital and Trauma Center has improved the accessibility and efficiency of dermatology care delivery.

METHODS

Retrospective, pre-post analysis of a pre-teledermatology cohort (June 2014-December 2014) compared with a post-teledermatology cohort (June 2017-December 2017).

RESULTS

Our analysis captured 11,586 patients. After implementation of teledermatology, waiting times for new patients decreased significantly (84.6 days vs 6.7 days; P < .001), total cases evaluated per month increased significantly (754 vs 901; P = .008), and number of cases evaluated per dermatologist-hour increased significantly (2.27 vs 2.63; P = .010). In the post-teledermatology period, 61.8% of teledermatology consults were managed without a clinic visit.

LIMITATIONS

We were unable to control for changes in demand for dermatology evaluations between the 2 periods and did not have a control group with which to compare our results.

CONCLUSION

The dermatology service was more accessible and more efficient after implementation of teledermatology, suggesting that capitated health care settings can benefit from implementation of a teledermatology system.
