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

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.

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.

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.

The Role of Dermoscopy in Provider-to-Provider Store-and-Forward Dermatology eConsults: A Scoping Review of the Recent Literature

Purpose of Review

This scoping review maps recent literature on dermatology provider-to-provider asynchronous store-and-forward (SAF) electronic consult (eConsult) platforms with dermoscopy. It offers a descriptive overview, highlighting benefits and challenges.

Recent Findings

Incorporating dermoscopy into SAF eConsults improves diagnostic accuracy for benign and malignant skin neoplasms. Diagnostic and treatment concordance with traditional face-to-face (FTF) visits is high. SAF eConsults with dermoscopy enhance access to dermatological care by improving triage and reducing wait times for FTF visits. Pediatric patients benefit with improved evaluation of melanocytic and vascular growths. eConsult platforms with dermoscopy serve as a telementoring opportunity for clinicians interested in improving their dermoscopy skills.

Summary

Adding dermoscopy to SAF eConsults is valuable and results in improved diagnostic accuracy and reduced need for FTF visits. Implementation barriers can be overcome through collaboration between primary care and dermatology. Dermoscopy in SAF eConsults has significant potential for managing skin conditions and reducing the burden caused by unnecessary FTF visit and biopsies.

Implementation and evaluation of a store-and-forward teledermatology workflow in a United States safety-net hospital urgent care emergency center: A retrospective cohort study

Background

Teledermatology (TD) is an important method for increasing access to care in outpatient settings. However, less is known regarding its use in emergency/urgent care centers.

Objective

To evaluate the effect of TD on urgent care emergency center (UCEC) dwell time and postencounter utilization.

Study type and methods

This retrospective cohort study evaluated patients in a safety-net hospital (Parkland Health, Dallas, Texas, USA) UCEC, who (1) received a TD consult in 2018, (2) were referred to dermatology clinic in 2017, or (3) were referred to dermatology clinic in 2018 without a TD consult.

Results

We evaluated 2024 patients from 2017 to 2018. Of the 973 referred to dermatology clinic in 2018, 332 (34%) received TD consultations. Mean dwell time for patients receiving TD was longer versus the 2017 cohort (303 vs 204 minutes, respectively). Patients receiving TD consultation with inflammatory skin conditions had lower odds of dermatology clinic visits compared with those that did not (odds ratio, 0.5; 95% CI, 0.3-0.8). Teledermatology was not associated with differences in repeat UCEC utilization.

Limitations

Single institution study and inability to account for differences in patient complexity.

Conclusion

TD increases dwell time in a safety-net hospital's UCEC but can reduce dermatology clinic utilization for patients with inflammatory skin conditions.

Accuracy of a Smartphone-Based Artificial Intelligence Application for Classification of Melanomas, Melanocytic Nevi, and Seborrheic Keratoses

Current artificial intelligence algorithms can classify melanomas at a level equivalent to that of experienced dermatologists. The objective of this study was to assess the accuracy of a smartphone-based "You Only Look Once" neural network model for the classification of melanomas, melanocytic nevi, and seborrheic keratoses. The algorithm was trained using 59,090 dermatoscopic images. Testing was performed on histologically confirmed lesions: 32 melanomas, 35 melanocytic nevi, and 33 seborrheic keratoses. The results of the algorithm's decisions were compared with those of two skilled dermatologists and five beginners in dermatoscopy. The algorithm's sensitivity and specificity for melanomas were 0.88 (0.71-0.96) and 0.87 (0.76-0.94), respectively. The algorithm surpassed the beginner dermatologists, who achieved a sensitivity of 0.83 (0.77-0.87). For melanocytic nevi, the algorithm outclassed each group of dermatologists, attaining a sensitivity of 0.77 (0.60-0.90). The algorithm's sensitivity for seborrheic keratoses was 0.52 (0.34-0.69). The smartphone-based "You Only Look Once" neural network model achieved a high sensitivity and specificity in the classification of melanomas and melanocytic nevi with an accuracy similar to that of skilled dermatologists. However, a bigger dataset is required in order to increase the algorithm's sensitivity for seborrheic keratoses.

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.

Inpatient Teledermatology: a Review

Purpose of Review

Inpatient teledermatology is a rapidly growing field with significant potential to add value and streamline patient care. This review summarizes the current literature on inpatient teledermatology, primarily focusing on its diagnostic and clinical management utility as compared to live dermatologic evaluation.

Recent Findings

The COVID-19 pandemic has accelerated the adoption of inpatient teledermatology, which has been shown to be comparable to live hospitalist evaluation for triage, diagnosis, and management of hospitalized patients for a wide variety of conditions. Despite its comparative cost-effectiveness and recent changes in reimbursement practices, inpatient teledermatology still lacks sufficient reimbursement incentive for widespread implementation.

Summary

Inpatient teledermatology is an effective, efficient, accurate, and cost-effective means of managing the hospital burden of skin disease, especially in areas where access to dermatologic care is limited. It is essential that dermatologists and referring providers comprehend the use and potential pitfalls of inpatient teledermatology to effectively incorporate it into hospital practice.

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.

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.

Testosterone replacement therapy in the era of telemedicine

The events of the 2019 SARS-CoV2 virus pandemic have all but ensured that telemedicine will remain an important aspect of patient care delivery. As health technologies evolve, so must physician practices. Currently, there is limited data on the management of testosterone replacement therapy (TRT) in the era of telemedicine. This review aims to explore the potential benefits and pitfalls of TRT management via telemedicine. We also propose a theoretical framework for TRT management via telemedicine. Telemedicine provides patients and physicians with a new mechanism for American Urological Association guideline-concordant TRT management that can increase patient access to care and provide a safe space for men who may otherwise not have been comfortable with in-person evaluation. However, there are significant limitations to the use of telemedicine for the management of TRT, including the inability to perform a physical exam, inability to administer specific medications, technological barriers, data security, and medical-legal considerations, and both patients and providers should engage in shared decision making before pursuing this approach. Understanding and acknowledging the potential pitfalls of telemedicine for TRT management will enable both patients and providers to achieve optimal outcomes and satisfaction.

A Desperate Need for Psoriasis Health Care in Remote Regions as Revealed by a Live Interactive Teledermatology Program Serving Penghu Islands in Taiwan Strait

Introduction: Several studies indicated that teledermatology is good for people living on offshore islands. However, what disease benefits the most from interactive dermatology geographically in offshore islands remain uncertain. Objectives: This study aimed to investigate the seasonal and geographical distribution with different diseases in remote regions of Penghu islands in Taiwan Strait, thus to study the medical needs for specific disease in remote islands. The cost differences among three models by professional dermatologists were analyzed. Methods: This interactive teledermatology program serving Penghu Hospital, Ministry of Health and Welfare (MOHW-PH, March 2020 to February 2021) from a medical center in Taiwan recruited 145 patients with 280 patient-visits. The seasons, the timing from residential houses to MOHW-PH, the number of disease diagnosis, and the numbers of teledermatology visits are compared. The association of the distance from residential houses to MOHW-PH with different disease diagnosis was analyzed. Results: Eczema (33%), dermatophytosis (13%), and psoriasis (11%) were most common. Seasonal analysis showed dermatophytosis and eczema are more common in summer and winter, respectively. Geographical analysis showed that psoriasis has relatively higher case numbers, higher visits per case, with cases living in longer distances. The patient satisfaction was good (>95%). Among the three care modes of dermatologist, the cost estimation of interactive teledermatology and in-person clinic were similar yearly (2.4-2.9 million New Taiwan Dollars, roughly 80,000-90,000 USD). Conclusions: The study indicates that health care for psoriasis, being underprivileged but in desperate need in distant regions, could be delivered with quality and satisfaction by interactive teledermatology.

Comanagement of Rashes by Primary Care Providers and Dermatologists: A Retrospective Study

BACKGROUND

There is a high demand for managing skin disease, and dermatologists are in short supply.

OBJECTIVES

To better understand how rashes and other specific skin conditions are co-managed by primary care providers (PCPs) and dermatologists, we estimated the frequency with which PCPs sought consultation with or referral to dermatology and the proportion of patients who had a follow-up dermatology office visit in the following 90 days.

DESIGN AND SETTING

The retrospective longitudinal study included 106,459 patients with a skin condition diagnosed by 3,830 PCPs, from January 2017 to March 2017.

METHODS

Comprehensive electronic medical record data with generalized linear mixed modeling accounted for patient factors including diagnosis and clustering by medical center and PCP.

RESULTS

PCPs escalated 9% of patients to dermatology through consultation or referral, while 5% required a follow-up dermatology office visit within 90 days. Patients with bullous, hair, or pigment conditions or psoriasis were most likely to be escalated. Clustering of escalation and follow-up visits was minimal in relation to medical center (intraclass correlation, 0.04 for both outcomes) or PCP (escalation, intraclass correlation, 0.16; follow-up visits, 0.09).

DISCUSSION

Improving primary care education in skin disease and, for certain skin conditions, standardizing approaches to workup, treatment, and escalation may further streamline care and reduce pressure on the dermatologist workforce.

CONCLUSION

PCPs managed 91% of rashes without consultation or referral to dermatology, and the frequency of patients scheduled for dermatology office visits after primary care was similar from one PCP to another.

Cost-minimization analysis of teledermatology versus conventional care in the Brazilian National Health System

Aims: Cost-minimization analysis (CMA) comparing the teledermatology service of the State of Santa Catarina, Brazil with the provision of conventional care, from the societal perspective. Patients & methods: All costs related to direct patient care were considered in calculation of outpatient costs. The evaluation was performed using the parameters avoided referrals and profile of hospitalizations. The economic analysis was developed through a decision tree. Results: Totally, 40% of 79,411 tests performed could be managed in primary care, avoiding commuting and expanding the patients' access. The CMA showed the teledermatology service had a cost per patient of US$196.04, and the conventional care of US$245.66. Conclusion: In this scenario, teledermatology proved to be a cost-saving alternative to conventional care, reducing commuting costs.

Pros and cons of eHealth: A systematic review of the literature and observations in Denmark

Objectives:

The main objectives of this article are to systematically review the recent literature on patient safety in relation to the use of eHealth and to investigate how the Danish authorities supervise private eHealth clinics with regard to patient safety.

Methods:

Original studies reporting the association between patient safety and the use of eHealth as a means of communication between patients and healthcare providers were included. Four literature databases were searched for English-language articles reporting results from cohort studies and clinical trials, published from 2015 until March 2021. Moreover, registered private eHealth clinics in Denmark were evaluated with reference to a recent national audit of patient safety issues in eHealth.

Results:

The literature search retrieved four intervention studies. The studies did not identify any particular patient safety risks associated with the use of eHealth. Many different authorized healthcare providers (preferably, doctors) apply eHealth in various contexts. eHealth is being used as the only form of contact between the healthcare provider and the patient, as a supplement to patient visitations in an outpatient clinic, or as a tool for communicating between two or more healthcare providers. The regulation of eHealth involves patient safety issues but also has interfaces to marketing, IT systems, and infrastructure. Supervision of eHealth includes the organization of clinics, handling patient charts, prescription medicine, patient legal rights, and patient transition. However, there are many interfaces in the division of responsibilities among the various governmental players.

Conclusion:

eHealth is being used increasingly and in many settings, although recently published intervention studies investigating patient safety issues by the use of eHealth are limited. A structured and continuous governmental control and regulation of patient safety in relation to the use of eHealth is warranted.
