DMpDP: a Diagnostic Multiple-patient DermoFeature Profile store-and-forward teledermoscopy system

Telehealth demand is rapidly growing along with the necessity of providing wide-scale services covering multiple patients at the same time. In this work, the development of a store-and-forward (SAF) teledermoscopy system was considered. The dermoFeatures profile (DP) was proposed to decrease the size of the original dermoscopy image using its most significant features in the form of a newly generated diagonal alignment to generate a small-sized image DP, which is based on the extraction of a weighted intensity-difference frequency (WIDF) features along with morphological features (MOFs). These DPs were assembled to establish a Diagnostic Multiple-patient DermoFeature Profile (DMpDP). Different arrangements are proposed, namely the horizontally aligned, the diagonal-based, and the sequential-based DMpDPs to support the SAF systems. The DMpDPs are then embedded in a recorded patient-information signal (RPS) using a weight factor β to boost the transmitted patient-information signal. The effect of the different transform domains, β values, and number of DPs within the DMpDP were investigated in terms of the diagnostic classification accuracy at the receiver based on the extracted DPs, along with the recorded signal quality evaluation metrics of the recovered RPS. The sequential-based DMpDP achieved the highest classification accuracy, under - 5 dB additive white Gaussian noise, with a realized signal-to-noise ratio of 98.79% during the transmission of 248 DPs using β = 100, and spectral subtraction filtering.

Barriers and Facilitators to Teledermatology and Tele-Eye Care in Department of Veterans Affairs Provider Settings: Qualitative Content Analysis

BACKGROUND

Veterans Affairs health care systems have been early adopters of asynchronous telemedicine to provide access to timely and high-quality specialty care services in primary care settings for veterans living in rural areas. Scant research has examined how to expand primary care team members' engagement in telespecialty care.

OBJECTIVE

This qualitative study aimed to explore implementation process barriers and facilitators to using asynchronous telespecialty care (teledermatology and tele-eye care services).

METHODS

In total, 30 participants including primary care providers, nurses, telehealth clinical technicians, medical and program support assistants, and administrators from 2 community-based outpatient clinics were interviewed. Semistructured interviews were conducted using an interview guide, digitally recorded, and transcribed. Interview transcripts were analyzed using a qualitative content analysis summative approach. Two coders reviewed transcripts independently. Discrepancies were resolved by consensus discussion.

RESULTS

In total, 3 themes were identified from participants' experiences: positive perception of telespecialty care, concerns and challenges of implementation, and suggestions for service refinement. Participants voiced that the telemedicine visits saved commute and waiting times and provided veterans in rural areas more access to timely medical care. The mentioned concerns were technical challenges and equipment failure, staffing shortages to cover both in-person and telehealth visit needs, overbooked schedules leading to delayed referrals, the need for a more standardized operation protocol, and more hands-on training with formative feedback among supporting staff. Participants also faced challenges with appointment cancellations and struggled to find ways to efficiently manage both telehealth and in-person visits to streamline patient flow. Nonetheless, most participants feel motivated and confident in implementing telespecialty care going forward.

CONCLUSIONS

This study provided important insights into the positive perceptions and ongoing challenges in telespecialty care implementation. Feedback from primary care teams is needed to improve telespecialty care service delivery for rural veterans.

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.

A Framework-Driven Systematic Review of the Barriers and Facilitators to Teledermatology Implementation

Purpose of Review

Telemedicine use in dermatology, termed “teledermatology”, offers a cost-effective model to improve healthcare efficiency and access. Only a minority of dermatology practices has integrated teledermatology into their practice prior to COVID-19. A thorough understanding of the barriers and facilitators may promote teledermatology adoption. Implementation science frameworks offer theoretically driven ways to assess factors affecting teledermatology implementation. This review uses a comprehensive implementation science framework to summarize barriers and facilitators of teledermatology implementation and appraises the quality of existing research.

Recent Findings

Technological characteristics of teledermatology (e.g., user-friendliness) and factors within the outer setting (e.g., reimbursement and legal considerations) were the most commonly reported barriers. No existing studies use a comprehensive implementation framework to identify factors influencing teledermatology implementation. Many included studies have a risk of bias in at least two of the five study quality indices evaluated.

Summary

This systematic review is the first study to summarize the existing teledermatology implementation literature into well-defined constructs from a comprehensive implementation science framework. Findings suggest future studies would benefit from the use of an implementation framework to reduce study bias, improve result comprehensiveness, facilitate comparisons across studies, and produce evidence-based resolutions to implementation barriers. Tools, resources, and recommendations to facilitate the use of an implementation framework in future studies are provided.

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.

Improved patient access and outcomes with the integration of an eConsult program (teledermatology) within a large academic medical center

BACKGROUND

Insurance, racial, and socioeconomic health disparities continue to pose significant challenges for access to dermatologic care. Studies applying teledermatology to increase access to underinsured individuals and ethnic minorities are limited.

OBJECTIVE

To determine how the implementation of a teledermatology program affects access to health care and patient outcomes.

METHODS

A cross-sectional evaluation was performed of all ambulatory dermatology referrals and electronic dermatology consultations (eConsults) at Ohio State University within a 25-month period.

RESULTS

Compared with ambulatory referrals, eConsults served more nonwhite patients (612 of 1698 [36.0%] vs 4040 of 16,073 [25.1%]; P < .001) and more Medicaid enrollees (459 of 1698 patients [27.0%] vs 3266 of 16,073 [20.3%]; P < .001). In addition, ambulatory referral patients were significantly less likely to attend their scheduled appointment compared with eConsult patients, as either "no-shows" (246 of 2526 [9.7%] vs 3 of 62 [4.8%]) or cancellations (742 of 2526 [29.4%] vs 8 of 62 [12.9%]; P = .003). There were fewer median days to extirpation for eConsult patients compared with ambulatory referral patients (interquartile range; 80.7 ± 79.8 vs 116.9 ± 86.6 days; P = .004).

CONCLUSION

Integrating dermatologic care through a telemedicine system can result in improved access for underserved patients through improved efficiency outcomes.

Teledermatology: from historical perspective to emerging techniques of the modern era: part I: History, rationale, and current practice

Telemedicine is the use of telecommunications technology to support health care at a distance. Technological advances have progressively increased the ability of clinicians to care for diverse patient populations in need of skin expertise. Dermatology relies on visual cues that are easily captured by imaging technologies, making it ideally suited for this care model. Moreover, there is a shortage of medical dermatologists in the United States, where skin disorders account for 1 in 8 primary care visits and specialists tend to congregate in urban areas. Even in regions where dermatologic expertise is readily accessible, teledermatology may serve as an alternative that streamlines health care delivery by triaging chief complaints and reducing unnecessary in-person visits. In addition, many patients in the developing world have no access to dermatologic expertise, rendering it possible for teledermatologists to make a significant contribution to patient health outcomes. Teledermatology also affords educational benefits to primary care providers and dermatologists, and enables patients to play a more active role in the health care process by promoting direct communication with dermatologists.

Impact of the Number of Dermatologists on Dermatology Biomedical Research: A Canadian Study

Background:

Fewer dermatologists than other clinical specialists are entering and being retained as physicians in the Canadian medical workforce. Studies suggest that dermatologist numbers may influence skin disease outcomes. No study has questioned whether the number of clinical dermatologists can influence academic productivity.

Objective:

To quantify the correlation of the number of dermatologists with biomedical scientific production in this field from 1996 to 2008 in Canada.

Methods:

Canadian dermatology biomedical scientific production from SCImago Journal & Country Rank (SJR) were merged with Canadian Medical Association (CMA) dermatologist demographic data. Linear regression analyses were used to model the relationships.

Results:

The low growth of dermatologist numbers by 8.16% in Canada from 1996 to 2008 correlates with a small increase in articles by 7.59% published in this subject area during this period. This has reduced the scientific importance of Canadian dermatology in the world.

Conclusion:

The number of dermatologists was a significant predictor of biomedical research production in the field of dermatology. This suggests that specialist availability may be one factor influencing dermatology research and publications.

Is telemonitoring an option against shortage of physicians in rural regions? Attitude towards telemedical devices in the North Rhine-Westphalian health survey, Germany

Background

General practitioners (GP) in rural areas of Germany are struggling to find successors for their private practices. Telemonitoring at home offers an option to support remaining GPs and specialists in ambulatory care.

Methods

We assessed the knowledge and attitude towards telemedicine in the population of North Rhine-Westphalia (NRW), Germany, in a population-based telephone survey.

Results

Out of 2,006 participants, 734 (36.6%) reported an awareness of telemedical devices. Only 37 participants (1.8%) have experience in using them. The majority of participants were in favour of using them in case of illness (72.2%). However, this approval declined with age. These findings were similar in rural and urban areas. Participants who were in favour of telemedicine (n = 1,480) strongly agreed that they would have to see their doctor less often, and that the doctor would recognize earlier relevant changes in their vital status. Participants who disliked to be monitored by telemedical devices preferred to receive immediate feedback from their physician. Especially, the elderly fear the loss of personal contact with their physician. They need the direct patient-physician communication.

Conclusions

The fear of being left alone with the technique needs to be compensated for today's elderly patients to enhance acceptance of home telemonitoring as support for remaining doctors either in the rural areas or cities.
