Multicentre randomised control trial comparing real time teledermatology with conventional outpatient dermatological care: societal cost-benefit analysis

TELEDerm: Implementing store-and-forward teledermatology consultations in general practice: Results of a cluster randomized trial

BACKGROUND

Although teledermatology has been proven internationally to be an effective and safe addition to the care of patients in primary care, there are few pilot projects implementing teledermatology in routine outpatient care in Germany. The aim of this cluster randomized controlled trial was to evaluate whether referrals to dermatologists are reduced by implementing a store-and-forward teleconsultation system in general practitioner practices.

METHODS

Eight counties were cluster randomized to the intervention and control conditions. During the 1-year intervention period between July 2018 and June 2019, 46 general practitioner practices in the 4 intervention counties implemented a store-and-forward teledermatology system with Patient Data Management System interoperability. It allowed practice teams to initiate teleconsultations for patients with dermatologic complaints. In the four control counties, treatment as usual was performed. As primary outcome, number of referrals was calculated from routine health care data. Poisson regression was used to compare referral rates between the intervention practices and 342 control practices.

RESULTS

The primary analysis revealed no significant difference in referral rates (relative risk  = 1.02; 95% confidence interval = 0.911-1.141; p = .74). Secondary analyses accounting for sociodemographic and practice characteristics but omitting county pairing resulted in significant differences of referral rates between intervention practices and control practices. Matched county pair, general practitioner age, patient age, and patient sex distribution in the practices were significantly related to referral rates.

CONCLUSIONS

While a store-and-forward teleconsultation system was successfully implemented in the German primary health care setting, the intervention's effect was superimposed by regional factors. Such regional factors should be considered in future teledermatology research.

A Telehealth and Telepsychiatry Economic Cost Analysis Framework: Scoping Review

Introduction: Despite a good evidence base for telepsychiatry (TP), economic cost analyses are infrequent and vary in quality. Methods: A scoping review was conducted based on the research question, "From the perspective of an economic cost analysis for telehealth and telepsychiatry, what are the most meaningful ways to ensure a study/intervention improved clinical care, provided value to participants, had population level impact, and is sustainable?" The search in seven databases focused on keywords in four concept areas: (1) economic cost analysis, (2) evaluation, (3) telehealth and telepsychiatry, and (4) quantifiable health status outcomes. The authors reviewed the full-text articles based on the inclusion (Medical Subject Headings [MeSH] of the keywords) and exclusion criteria. Results: Of a total of 2,585 potential references, a total of 99 articles met the inclusion criteria. The evaluation of telehealth and TP has focused on access, quality, patient outcomes, feasibility, effectiveness, outcomes, and cost. Cost-effectiveness, cost-benefit, and other analytic models are more common with telehealth than TP studies, and these studies show favorable clinical, quality of life, and economic impact. A standard framework for economic cost analysis should include: an economist for planning, implementation, and evaluation; a tool kit or guideline; comprehensive analysis (e.g., cost-effectiveness or cost-benefit) with an incremental cost-effectiveness ratio; measures for health, quality of life, and utility outcomes for populations; methods to convert outcomes into economic benefits (e.g., monetary, quality of adjusted life year); broad perspective (e.g., societal perspective); sensitivity analysis for uncertainty in modeling; and adjustments for differential timing (e.g., discounting and future costs). Conclusions: Technology assessment and economic cost analysis-such as effectiveness and implementation science approaches-contribute to clinical, training, research, and other organizational missions. More research is needed with a framework that enables comparisons across studies and meta-analyses.

A Call to Action: Evidence for the Military Integration of Teledermoscopy in a Pandemic Era

Skin disease remains a common complaint among deployed service members. To mitigate the limited supply of dermatologists in the U.S. Military Health System, teledermatology has been harnessed as a specialist extender platform, allowing for online consultations in remote deployed settings. Operational teledermatology has played a critical role in reductions of medical evacuations with significant cost-savings. When direct in-person lesion visualization is unattainable, teledermoscopy can be harnessed as an effective diagnostic tool to distinguish suspicious skin lesions. Teledermoscopy has the versatile capacity for streamlined incorporation into the existing asynchronous telemedicine platforms utilized worldwide among deployed U.S. military healthcare providers. In terms of clinical utility, teledermoscopy offers a unique and timely opportunity to improve diagnostic accuracy, early detection rates, and prognostic courses for dermatological conditions. Such improvements will further reduce medical evacuations and separations, thereby improving mission readiness and combat effectiveness. As mission goals are safeguarded, associated operational budget costs are also preserved. This innovative, cost-effective technology merits integration into the U.S. Military Health System (MHS).

Effect of COVID-19 Pandemic on Patient Utilization of the Telemedicine Services in Dubai

<b><i>Introduction:</i></b> Telemedicine was launched in Dubai in December 2019. The service provided live interaction between patients and physicians through videos simulating a consultation in a clinic. <b><i>Methods:</i></b> This study is a multicenter comparative cross-sectional retrospective study that included 13 health centers in Dubai. The data in this study were taken before and during the coronavirus (COVID-19) pandemic retrospectively. All patients from both telemedicine and primary health care (PHC) clinic visits were included. <b><i>Results and Discussion:</i></b> A total of 121,035 patients were involved in this study; there were 55,622 patients before COVID-19 and 65,413 patients during the COVID-19 pandemic. During the coronavirus pandemic, patient utilization of telemedicine increased significantly in comparison to patient visits to the PHC centers. Before the COVID-19 pandemic, only 104 (0.2%) patients used telemedicine, while during the pandemic, the utilization of telemedicine increased to 9,183 (14%). More females than males preferred telemedicine use over visiting the PHC center. With the pandemic, elder patients used telemedicine more than the younger age groups. Telemedicine was used for different types of consultations such as acute, chronic, and COVID-19 related. The most common type of consultation in telemedicine during the pandemic was for chronic diseases (67.7%). <b><i>Conclusion:</i></b> In this comparative study, more patients used telemedicine in the time of COVID-19 pandemic whether it was for acute, chronic, or CO­VID-19-related consultations. Telemedicine proved to be a very useful tool at the time of disasters such as the COVID-19 pandemic.

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.

Lameness in dairy cows: farmer perceptions and automated detection technology

This Research Reflection provides an overview of three interrelated topics: (i) lameness in dairy cows, demonstrating the underpinning importance of the condition, (ii) dairy farmer detection, diagnosis and treatment of lameness and associated foot lesions as well as dairy farmer perceptions towards the condition and (iii) lameness detection technologies, and their potential application on farm to automate the detection of lameness in commercial dairy herds. The presented literature clearly demonstrates that lameness is a major health issue in dairy herds, compromising dairy cow welfare and productivity, and resulting in significant economic implications for dairy farmers. Despite this, dairy farmers fail to perceive lameness as a serious threat to their dairy business. This restricted perception of the importance of lameness may be a product of limited ability to detect lame cows. Many automated lameness detection technologies have been proposed to assist dairy farmers in managing their herds. However, limitations such as cost, performance and dairy farmer perception of the usefulness of these technologies, has lead to poor uptake. It can, therefore, be concluded that there is a need to more thoroughly evaluate the effectiveness of these technologies under on-farm conditions, potentially in the form of a demonstration farm network. This will allow generation of the necessary data required to show dairy farmers that these technologies are reliable and are economically rational for their dairy business.

Virtually Serving the Underserved: Resident Perceptions of Telemedicine Use While Training During Coronavirus Disease 2019

Background: To adapt during the coronavirus disease 2019 (COVID-19) pandemic, a large safety-net hospital in Atlanta, Georgia and other hospitals across the United Sates, increased telemedicine (TM) for outpatient visits. The impact on resident physicians, including minority providers, had not yet been reported. We aimed to assess how primary care residents perceived increased TM in clinics during the pandemic, and assess resident burnout. Materials and Methods: An online survey was sent to 60 internal medicine (IM) and 18 family medicine (FM) residents who used TM to treat underserved patients, from March to May 2020, at the onset of the COVID-19 pandemic. The questionnaire included questions on resident demographics, satisfaction with TM, screening capability for COVID-19, effectiveness for patient education on COVID-19, impact on patient interactions and time management. Burnout was assessed with the Abbreviated Maslach Burnout Inventory. Results: A majority (62 of 78) eligible residents (79.5%) responded to the survey. Ninety-one percent of residents agreed that TM was a secure alternative to face-to-face encounters. Seventy-nine percent used it to screen for signs/symptoms of COVID-19 and 93% provided patient education on COVID-19. Average visit length decreased by 10-20 min with TM. Post-TM, scores for overall burnout were decreased (p = 0.0003) and less residents in total exhibited burnout (p = 0.0156). Discussion and Conclusions: IM and FM residents viewed TM as an efficient way to screen for and provide education on COVID-19, as well as a secure alternative to face-to-face encounters. With increased used of TM during COVID-19, there was decreased burnout among primary care residents.

Teledermatology in 2020: past, present and future perspectives

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

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.

Mobile technologies to support healthcare provider to healthcare provider communication and management of care

BACKGROUND

The widespread use of mobile technologies can potentially expand the use of telemedicine approaches to facilitate communication between healthcare providers, this might increase access to specialist advice and improve patient health outcomes.

OBJECTIVES

To assess the effects of mobile technologies versus usual care for supporting communication and consultations between healthcare providers on healthcare providers' performance, acceptability and satisfaction, healthcare use, patient health outcomes, acceptability and satisfaction, costs, and technical difficulties.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase and three other databases from 1 January 2000 to 22 July 2019. We searched clinical trials registries, checked references of relevant systematic reviews and included studies, and contacted topic experts.

SELECTION CRITERIA

Randomised trials comparing mobile technologies to support healthcare provider to healthcare provider communication and consultations compared with usual care.

DATA COLLECTION AND ANALYSIS

We followed standard methodological procedures expected by Cochrane and EPOC. We used the GRADE approach to assess the certainty of the evidence.

MAIN RESULTS

We included 19 trials (5766 participants when reported), most were conducted in high-income countries. The most frequently used mobile technology was a mobile phone, often accompanied by training if it was used to transfer digital images. Trials recruited participants with different conditions, and interventions varied in delivery, components, and frequency of contact. We judged most trials to have high risk of performance bias, and approximately half had a high risk of detection, attrition, and reporting biases. Two studies reported data on technical problems, reporting few difficulties. Mobile technologies used by primary care providers to consult with hospital specialists We assessed the certainty of evidence for this group of trials as moderate to low. Mobile technologies: - probably make little or no difference to primary care providers following guidelines for people with chronic kidney disease (CKD; 1 trial, 47 general practices, 3004 participants); - probably reduce the time between presentation and management of individuals with skin conditions, people with symptoms requiring an ultrasound, or being referred for an appointment with a specialist after attending primary care (4 trials, 656 participants); - may reduce referrals and clinic visits among people with some skin conditions, and increase the likelihood of receiving retinopathy screening among people with diabetes, or an ultrasound in those referred with symptoms (9 trials, 4810 participants when reported); - probably make little or no difference to patient-reported quality of life and health-related quality of life (2 trials, 622 participants) or to clinician-assessed clinical recovery (2 trials, 769 participants) among individuals with skin conditions; - may make little or no difference to healthcare provider (2 trials, 378 participants) or participant acceptability and satisfaction (4 trials, 972 participants) when primary care providers consult with dermatologists; - may make little or no difference for total or expected costs per participant for adults with some skin conditions or CKD (6 trials, 5423 participants). Mobile technologies used by emergency physicians to consult with hospital specialists about people attending the emergency department We assessed the certainty of evidence for this group of trials as moderate. Mobile technologies: - probably slightly reduce the consultation time between emergency physicians and hospital specialists (median difference -12 minutes, 95% CI -19 to -7; 1 trial, 345 participants); - probably reduce participants' length of stay in the emergency department by a few minutes (median difference -30 minutes, 95% CI -37 to -25; 1 trial, 345 participants). We did not identify trials that reported on providers' adherence, participants' health status and well-being, healthcare provider and participant acceptability and satisfaction, or costs. Mobile technologies used by community health workers or home-care workers to consult with clinic staff We assessed the certainty of evidence for this group of trials as moderate to low. Mobile technologies: - probably make little or no difference in the number of outpatient clinic and community nurse consultations for participants with diabetes or older individuals treated with home enteral nutrition (2 trials, 370 participants) or hospitalisation of older individuals treated with home enteral nutrition (1 trial, 188 participants); - may lead to little or no difference in mortality among people living with HIV (RR 0.82, 95% CI 0.55 to 1.22) or diabetes (RR 0.94, 95% CI 0.28 to 3.12) (2 trials, 1152 participants); - may make little or no difference to participants' disease activity or health-related quality of life in participants with rheumatoid arthritis (1 trial, 85 participants); - probably make little or no difference for participant acceptability and satisfaction for participants with diabetes and participants with rheumatoid arthritis (2 trials, 178 participants). We did not identify any trials that reported on providers' adherence, time between presentation and management, healthcare provider acceptability and satisfaction, or costs.

AUTHORS' CONCLUSIONS

Our confidence in the effect estimates is limited. Interventions including a mobile technology component to support healthcare provider to healthcare provider communication and management of care may reduce the time between presentation and management of the health condition when primary care providers or emergency physicians use them to consult with specialists, and may increase the likelihood of receiving a clinical examination among participants with diabetes and those who required an ultrasound. They may decrease the number of people attending primary care who are referred to secondary or tertiary care in some conditions, such as some skin conditions and CKD. There was little evidence of effects on participants' health status and well-being, satisfaction, or costs.

Feasibility of Gynaecologist Led Lynch Syndrome Testing in Women with Endometrial Cancer

A barrier to Lynch syndrome testing is the need for prior genetic counselling, a resource demanding process for both patients and healthcare services. We explored the impact of gynaecologist led Lynch syndrome testing in women with endometrial cancer. Women were approached before surgery, on the day of surgery or during routine follow up. Lynch syndrome testing was offered irrespective of age, family history or tumour characteristics. Women's reasons for being tested were explored using the Motivations and Concerns for GeNEtic Testing (MACGNET) instrument. The short form State-Trait Anxiety Inventory (STAI-6) was used to measure anxiety levels. Only 3/305 women declined Lynch syndrome testing. In total, 175/220 completed MACGNET and STAI-6 psychological instruments. The consent process took an average of 7min 36sec (SD 5min 16sec) to complete. The point of care at which consent was taken (before, day of surgery, during follow up) did not influence motivation for Lynch syndrome testing. Anxiety levels were significantly lower when women were consented during follow up (mean reversed STAI-6 score 32 vs 42, p = 0.001). Anxiety levels were not affected by familial cancer history (p = 0.41). Gynaecologist led Lynch syndrome testing is feasible and may even be desirable in endometrial cancer, especially when offered during routine follow up.

Enhancing the Sustainable Goal of Access to Healthcare: Findings from a Literature Review on Telemedicine Employment in Rural Areas

Fighting health inequalities is a challenge addressed by the United Nations Strategic Development Goals (UN-SDGs). Particularly, people living in rural areas suffer from a lack of health infrastructure, which would jeopardize their inclusion in universal coverage for specialist care. Delivering valuable healthcare in underserved areas can be achieved through the employment of new technical innovations, such as telemedicine, which improves service delivery processes. Accordingly, this paper discusses how telemedicine strategies have enhanced the sustainability of right of “access to healthcare” in rural areas. Once we derived the sustainability pillars for healthcare from the UN-SDGs 3 and 10 according to the WHO innovation assessment metrics, a PRISMA-based literature review was conducted using the Scopus database. English, peer-reviewed articles/reviews from 1973 to 2019 were considered. The enquiry covers two analyses: (i) quantitative-bibliometric on 2267 papers; and (ii) qualitative-narrative on the 30 most significant papers. Interest about the topic has increased in the last decade following digitalization diffusion. The most productive and collaborative countries are those with huge dimensions and under financial restrictions. From a sustainability-oriented standpoint, telemedicine enhances both emergency and diagnostic healthcare in rural areas by decreasing the cost of services, expanding coverage of specialist cares, and increasing the quality of the outcomes. For health policies, telemedicine can be considered a suitable solution for providing cost-effective and sustainable healthcare.

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.

Cost-Effectiveness of Telemedicine in Remote Orthopedic Consultations: Randomized Controlled Trial

BACKGROUND

Telemedicine consultations using real-time videoconferencing has the potential to improve access and quality of care, avoid patient travels, and reduce health care costs.

OBJECTIVE

The aim of this study was to examine the cost-effectiveness of an orthopedic videoconferencing service between the University Hospital of North Norway and a regional medical center in a remote community located 148 km away.

METHODS

An economic evaluation based on a randomized controlled trial of 389 patients (559 consultations) referred to the hospital for an orthopedic outpatient consultation was conducted. The intervention group (199 patients) was randomized to receive video-assisted remote orthopedic consultations (302 consultations), while the control group (190 patients) received standard care in outpatient consultation at the hospital (257 consultations). A societal perspective was adopted for calculating costs. Health outcomes were measured as quality-adjusted life years (QALYs) gained. Resource use and health outcomes were collected alongside the trial at baseline and at 12 months follow-up using questionnaires, patient charts, and consultation records. These were valued using externally collected data on unit costs and QALY weights. An extended sensitivity analysis was conducted to address the robustness of the results.

RESULTS

This study showed that using videoconferencing for orthopedic consultations in the remote clinic costs less than standard outpatient consultations at the specialist hospital, as long as the total number of patient consultations exceeds 151 per year. For a total workload of 300 consultations per year, the annual cost savings amounted to €18,616. If costs were calculated from a health sector perspective, rather than a societal perspective, the number of consultations needed to break even was 183.

CONCLUSIONS

This study showed that providing video-assisted orthopedic consultations to a remote clinic in Northern Norway, rather than having patients travel to the specialist hospital for consultations, is cost-effective from both a societal and health sector perspective. This conclusion holds as long as the activity exceeds 151 and 183 patient consultations per year, respectively.

Teledermatology for diagnosing skin cancer in adults

BACKGROUND

Early accurate detection of all skin cancer types is essential to guide appropriate management and to improve morbidity and survival. Melanoma and squamous cell carcinoma (SCC) are high-risk skin cancers which have the potential to metastasise and ultimately lead to death, whereas basal cell carcinoma (BCC) is usually localised with potential to infiltrate and damage surrounding tissue. Anxiety around missing early curable cases needs to be balanced against inappropriate referral and unnecessary excision of benign lesions. Teledermatology provides a way for generalist clinicians to access the opinion of a specialist dermatologist for skin lesions that they consider to be suspicious without referring the patients through the normal referral pathway. Teledermatology consultations can be 'store-and-forward' with electronic digital images of a lesion sent to a dermatologist for review at a later time, or can be live and interactive consultations using videoconferencing to connect the patient, referrer and dermatologist in real time.

OBJECTIVES

To determine the diagnostic accuracy of teledermatology for the detection of any skin cancer (melanoma, BCC or cutaneous squamous cell carcinoma (cSCC)) in adults, and to compare its accuracy with that of in-person diagnosis.

SEARCH METHODS

We undertook a comprehensive search of the following databases from inception up to August 2016: Cochrane Central Register of Controlled Trials, MEDLINE, Embase, CINAHL, CPCI, Zetoc, Science Citation Index, US National Institutes of Health Ongoing Trials Register, NIHR Clinical Research Network Portfolio Database and the World Health Organization International Clinical Trials Registry Platform. We studied reference lists and published systematic review articles.

SELECTION CRITERIA

Studies evaluating skin cancer diagnosis for teledermatology alone, or in comparison with face-to-face diagnosis by a specialist clinician, compared with a reference standard of histological confirmation or clinical follow-up and expert opinion. We also included studies evaluating the referral accuracy of teledermatology compared with a reference standard of face-to-face diagnosis by a specialist clinician.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted all data using a standardised data extraction and quality assessment form (based on QUADAS-2). We contacted authors of included studies where there were information related to the target condition of any skin cancer missing. Data permitting, we estimated summary sensitivities and specificities using the bivariate hierarchical model. Due to the scarcity of data, we undertook no covariate investigations for this review. For illustrative purposes, we plotted estimates of sensitivity and specificity on coupled forest plots for diagnostic threshold and target condition under consideration.

MAIN RESULTS

The review included 22 studies reporting diagnostic accuracy data for 4057 lesions and 879 malignant cases (16 studies) and referral accuracy data for reported data for 1449 lesions and 270 'positive' cases as determined by the reference standard face-to-face decision (six studies). Methodological quality was variable with poor reporting hindering assessment. The overall risk of bias was high or unclear for participant selection, reference standard, and participant flow and timing in at least half of all studies; the majority were at low risk of bias for the index test. The applicability of study findings were of high or unclear concern for most studies in all domains assessed due to the recruitment of participants from secondary care settings or specialist clinics rather than from primary or community-based settings in which teledermatology is more likely to be used and due to the acquisition of lesion images by dermatologists or in specialist imaging units rather than by primary care clinicians.Seven studies provided data for the primary target condition of any skin cancer (1588 lesions and 638 malignancies). For the correct diagnosis of lesions as malignant using photographic images, summary sensitivity was 94.9% (95% confidence interval (CI) 90.1% to 97.4%) and summary specificity was 84.3% (95% CI 48.5% to 96.8%) (from four studies). Individual study estimates using dermoscopic images or a combination of photographic and dermoscopic images generally suggested similarly high sensitivities with highly variable specificities. Limited comparative data suggested similar diagnostic accuracy between teledermatology assessment and in-person diagnosis by a dermatologist; however, data were too scarce to draw firm conclusions. For the detection of invasive melanoma or atypical intraepidermal melanocytic variants both sensitivities and specificities were more variable. Sensitivities ranged from 59% (95% CI 42% to 74%) to 100% (95% CI 48% to 100%) and specificities from 30% (95% CI 22% to 40%) to 100% (95% CI 93% to 100%), with reported diagnostic thresholds including the correct diagnosis of melanoma, classification of lesions as 'atypical' or 'typical, and the decision to refer or to excise a lesion.Referral accuracy data comparing teledermatology against a face-to-face reference standard suggested good agreement for lesions considered to require some positive action by face-to-face assessment (sensitivities of over 90%). For lesions considered of less concern when assessed face-to-face (e.g. for lesions not recommended for excision or referral), agreement was more variable with teledermatology specificities ranging from 57% (95% CI 39% to 73%) to 100% (95% CI 86% to 100%), suggesting that remote assessment is more likely recommend excision, referral or follow-up compared to in-person decisions.

AUTHORS' CONCLUSIONS

Studies were generally small and heterogeneous and methodological quality was difficult to judge due to poor reporting. Bearing in mind concerns regarding the applicability of study participants and of lesion image acquisition in specialist settings, our results suggest that teledermatology can correctly identify the majority of malignant lesions. Using a more widely defined threshold to identify 'possibly' malignant cases or lesions that should be considered for excision is likely to appropriately triage those lesions requiring face-to-face assessment by a specialist. Despite the increasing use of teledermatology on an international level, the evidence base to support its ability to accurately diagnose lesions and to triage lesions from primary to secondary care is lacking and further prospective and pragmatic evaluation is needed.

Patient satisfaction with dermatology teleconsultation by using MedX

BACKGROUND

The development of telecommunication has strongly affected comprehensive scientific disciplines, including medical sciences.

OBJECTIVE

This study aims to assess the patient satisfaction of the teleconsultation system used for the consultation of dermatological follow-up care.

METHODS

The study was performed cross sectional patient satisfaction survey method conducted between February and April 2017 to determine patient satisfaction using MedX teleconsultation system. The patient sample of the current study was recruited from cosmetic laser clinic, Wanfang and Taipei Medical University hospital. The study was performed on 32 patient (n = 32) participants. All of them were at least university graduate. Consultants and patients were handled using the Android-based MedX mobile application, which is available through an application for Google Android cellular telephones. Its application consists of a demographic information, structured step-by-step questionnaire, essential medical information about each patient, and digital images of skin lesions.

RESULTS

28 patients completed the questionnaire. The mean ± SD age of the patients was 27.25 ± 4.039 years; 78.6% were women. The study shows that respondents have reported a high level (85.8%) of mean overall satisfaction for the teleconsultation service. The usability of the system has highest satisfaction rate of 90.5% among the other subscales especially in terms of data transfer and data displayed. Responses of the patient satisfaction questionnaire were analyzed by age and gender, no statistically significant difference between the variables was found.

CONCLUSION

Patients have shown high satisfaction with teleconsultation service and it is well accepted in the management of cosmetic dermatology service. In the future, MedX application can be integrated into other instant messaging applications such as Line, thus allowing doctors and patients to easily communicate with each other.

Video clinics versus standard face-to-face appointments for liver transplant patients in routine hospital outpatient care: study protocol for a pragmatic randomised evaluation of myVideoClinic

Background

Video clinics, where patients can have a hospital appointment with their clinician from home, are emerging in practice, but their effectiveness is unclear. This study will evaluate whether a video clinic implemented at the University Hospitals Birmingham (UHB) NHS Foundation Trust improves patient satisfaction compared to standard face-to-face appointments for liver transplant patients.

Methods

This will be a parallel, two-arm, statistician-blinded, randomised evaluation. Clinically stable liver patients at 1 to 5 years post-transplant (n = 180) will be randomised in equal numbers to video clinic appointments (intervention) or standard face-to-face appointments (control). The intervention group will have outpatient appointments from home via a secure video link accessed through the UHB patient portal. All patients will complete baseline questionnaires before randomisation and electronic follow-up questionnaires after each follow-up appointment during the subsequent 12 months. The primary outcome is the difference in scores between groups for three domains of patient satisfaction, namely ‘convenience of location’, ‘getting through to the office by phone’ and ‘length of time waiting’ (modified Visit-Specific Satisfaction Instrument). Secondary outcomes include quality of life (EQ-5D-5 L), costs, clinical contacts and user experience. Statistical analysis will be descriptive and performed on an intention-to-treat basis. The primary outcome will be analysed using baseline and 3-, 6-, 9- and 12-month questionnaires (according to patient follow-up appointment frequency) and comparisons made between study arms. A within-trial cost consequences analysis will be undertaken on the economic data. Patients (n = 8), carers/family members (n = 6) and health professionals (n = 14) will be interviewed about the experience of video clinics and the interviews will be analysed using thematic analysis.

Discussion

This study will allow an in depth understanding of whether video clinics can improve patient satisfaction with their care. In addition, the intervention could save patients time and costs, removing the need to travel long distances for outpatient appointments. Video clinics may be applicable to a wide range of other clinical settings and health conditions. The study has been approved by the NHS Health Research Authority and a National Research Ethics Committee (Ref: 17/WM/0338) and research governance approval has been obtained from UHB (Ref: RRK6080).

Teledermatology: A Review and Update

Telemedicine is slowly transforming the way in which healthcare is delivered and has the potential to improve access to subspecialty expertise, reduce healthcare costs, and improve the overall quality of care. While many subspecialty fields within medicine today have either experimented with or begun to implement telemedicine platforms to enable remote consultation and care, dermatology is particularly suited for this care system as skin disorders are uniquely visible to the human eye. Through teledermatology, diagnostic images of skin disorders with accompanying clinical histories can be remotely reviewed by teledermatologists by any number of modalities, such as photographic clinical images or live video teleconferencing. Diagnoses and treatment recommendations can then be rendered and implemented remotely. The evidence to date supports both its diagnostic and treatment accuracy and its cost effectiveness. Administrative, regulatory, privacy, and reimbursement policies surrounding this dynamic field continue to evolve. In this review, we examine the history, evidence, and administrative landscape surrounding teledermatology and discuss current practice guidelines and ongoing controversies.

Telemedicine: A systematic review of economic evaluations

Background: Telemedicine is an expanded term in health information technology that comprises procedures for transmitting medical information electronically to improve patients’ health status. The objective of this research is to evaluate the cost-effectiveness of telemedicine interventions in various specialty areas.

Methods: The Cochrane Library and Centre for Review and Dissemination were searched up to February 2013 using Mesh. Studies that compared any kind of telemedicine with any other routine care technique and used cost per health utility unit’s outcomes were included.

Results: Twenty-one articles were included. According to the included studies, it seems that using telemedicine in cardiology can be effective and cost-effective enough but pre-hospital telemedicine diagnostics program are likely to have little impact on acute myocardial infarction fatality. In pulmonary, telemedicine can be a cost-effective strategy for delivering outpatient pulmonary care to rural populations which have limited access to specialized services, but telemedicine is not cost- effective in asthma and airways cancer. In ophthalmology, especially in the diagnosis of diabetic retinopathy, the use of telemedicine is a cost-effective tool. In dermatology, telemedicine is not cost-effective enough in comparison of conventional cares. In other fields such as physical activity and diet, eating disorder, tele-ICU, psychotherapy for depression and telemedicine on ships, telemedicine can be used as a cost-effective tool for treatments or cares.

Conclusion: Most of the included studies confirmed that telemedicine is cost-effective for applying in major medical fields such as cardiology; but in dermatology, papers could not confirm the positive capability of telemedicine.

Medicare Part D Payments for Topical Steroids: Rising Costs and Potential Savings

Importance

Rising pharmaceutical costs in the United States are an increasing source of financial burden for payers and patients. Although topical steroids are among the most commonly prescribed medications in dermatology, there are limited data on steroid-related spending and utilization.

Objective

To characterize Medicare and patient out-of-pocket costs for topical steroids, and to model potential savings that could result from substitution of the cheapest topical steroid from the corresponding potency class.

Design, Setting, and Participants

This study was a retrospective cost analysis of the Medicare Part D Prescriber Public Use File, which details annual drug utilization and spending on both generic and branded drugs from 2011 to 2015 by Medicare Part D participants who filled prescriptions for topical steroids.

Main Outcomes and Measures

Total and potential Medicare and out-of-pocket patient spending. Costs were adjusted for inflation and reported in 2015 dollars.

Results

Medicare Part D expenditures on topical steroids between 2011 and 2015 were $2.3 billion. Patients' out-of-pocket spending for topical steroids over the same period was $333.7 million. The total annual spending increased from $237.6 million to $775.9 million, an increase of 226.5%. Patients' annual out-of-pocket spending increased from $41.4 million to $101.8 million, an increase of 145.9%. The total number of prescriptions were 7.7 million in 2011 and 10.6 million in 2015, an increase of 37.0%. Generic medication costs accounted for 97.8% of the total spending during this time period. The potential health care savings and out-of-pocket patient savings from substitution of the cheapest topical steroid within the corresponding potency class were $944.8 million and $66.6 million, respectively.

Conclusions and Relevance

Most topical steroids prescribed were generic drugs. There has been a sharp increase in Medicare and out-of-pocket spending on topical steroids that is driven by higher costs for generics. Use of clinical decision support tools to enable substitution of the most affordable generic topical steroid from the corresponding potency class may reduce drug expenditures.

Telemedicine with mobile devices and augmented reality for early postoperative care

Advanced features are being added to telemedicine paradigms to enhance usability and usefulness. Virtual Interactive Presence (VIP) is a technology that allows a surgeon and patient to interact in a "merged reality" space, to facilitate both verbal, visual, and manual interaction. In this clinical study, a mobile VIP iOS application was introduced into routine post-operative orthopedic and neurosurgical care. Survey responses endorse the usefulness of this tool, as it relates to The virtual interaction provides needed virtual follow-up in instances where in-person follow-up may be limited, and enhances the subjective patient experience.

Telemedicine in dermatology: findings and experiences worldwide - a systematic literature review

Telemedicine has become an important element of health care in many countries and profited from the technological progress of the last two decades. Due to the visual character of the dermatological specialty, teledermatology in particular participated in that development and is becoming a major tool in dermatological consultation. The objective of this article was to identify the use of teledermatology across the world based on published original articles. A systematic literature search of the MEDLINE and Embase databases for eligible publications (predefined inclusion and exclusion criteria) and a cross-validation search were conducted. Search results were reviewed systematically. The search resulted in 204 publications meeting the inclusion criteria for analysis. The highest number of published studies on teledermatology was performed in the United States, followed by the United Kingdom, Spain, the Netherlands, Italy and Austria. The majority of dermatological indications for telemedical consultations were not specified or included various kinds of skin diseases, followed by skin cancer and wounds. Research questions predominantly focused on concordance, effectiveness and cost-effectiveness to determine the value. Teledermatology proved to be a reliable consultation tool in the majority of studies. If specified, telemedicine was used in daily dermatological routine for patient management purposes, to consult patients in peripheral locations, or for medical support in nursing homes or home care settings. The application of teledermatology worldwide is highest in North American and European countries, while countries with poor geographical distribution of physicians seem to be under-represented in teledermatological use, as concluded from publication output. Regarding indications, comparison with classic consultation and area of application, most studies were of general nature. For precise determination of the value, systematic studies would be needed. However, teledermatology is already accepted as a valid tool.

A Systematic Review of the Economic Evaluation of Telemedicine in Japan

Objectives:

There is no systematic review on economic evaluations of telemedicine in Japan, despite over 1000 trials implemented. Our systematic review aims to examine whether Japan’s telemedicine is cost-saving or cost-effective, examine the methodological rigorousness of the economic evaluations, and discuss future studies needed to improve telemedicine’s financial sustainability.

Methods:

We searched five databases, including two Japanese databases, to find peer-reviewed articles published between January 1, 2000 and December 31, 2014 in English and Japanese that performed economic evaluations of Japan’s telemedicine programs. The methodological rigorousness of the economic analyses was assessed with a well-established checklist. We calculated the benefit-to-cost ratio (BCR) when a reviewed study reported related data but did not report the BCR. All cost values were adjusted to 2014 US dollars.

Results:

Among the 17 articles identified, six studies reported on settings connecting physicians for specialist consultations, and eleven studies on settings connecting healthcare providers and patients at home. There are three cost-benefit analyses and three cost-minimization analyses. The remaining studies measured the benefit of telemedicine only, using medical expenditure saved or users’ willingness-to-pay. There was substantial diversity in the methodological rigorousness. Studies on teledermatology and teleradiology indicated a favorable level of economic efficiency. Studies on telehomecare gave mixed results. One cost-benefit analysis on telehomecare indicated a low economic efficiency, partly due to public subsidy rules, e.g., a too short budget period.

Conclusions:

Overall, telemedicine programs in Japan were indicated to have a favorable level of economic efficiency. However, the scarcity of the economic literature indicates the need for further rigorous economic evaluation studies.

Influences on teleconsultation project utilization rates: the role of dominant logic

Background

This research analyzes teleconsultation from both a mechanistic and complex adaptive system (CAS) dominant logic in order to further understand the influence of dominant logic on utilization rates of teleconsultation projects. In both dominant logics, the objective of teleconsultation projects is to increase access to and quality of healthcare delivery in a cost efficient manner. A mechanistic dominant logic perceives teleconsultation as closely resembling the traditional service delivery model, while a CAS dominant logic focuses on the system’s emergent behavior of learning resulting from the relationships and interactions of participating healthcare providers.

Methods

Qualitative case studies of 17 teleconsultation projects that were part of four health sciences center (HSC) based telemedicine networks was utilized. Data were collected at two points in time approximately 10 years apart. Semi-structured interviews of 85 key informants (clinicians, administrators, and IT professionals) involved in teleconsultation projects were the primary data collection method.

Results

The findings indicated that the emergent behavior of effective and sustainable teleconsultation projects differed significantly from what was anticipated in a mechanistic dominant logic. Teleconsultation projects whose emergent behavior focused on continuous learning enabled remote site generalists to manage and treat more complex cases and healthcare problems on their own without having to refer to HSC specialists for assistance. In teleconsultation projects that continued to be effectively utilized, participant roles evolved and were expanded. Further, technology requirements for teleconsultation projects whose emergent behavior was learning did not need to be terribly sophisticated.

Conclusions

When a teleconsultation project is designed with a mechanistic dominant logic, it is less likely to be sustained, whereas a teleconsultation project designed with a CAS dominant logic is more likely to be sustained. Consistent with a CAS dominant logic, teleconsultation projects that continued to be utilized involved participants taking on new roles and continuously learning. This continuous learning enabled remote site generalists to better handle the constantly changing nature of the problems faced. A CAS dominant logic provides a theoretical framework which explains why the teleconsultation literature about the role of technology, which is based on a mechanistic dominate logic, does not have adequate explanatory power.

Trial of low-cost teledermatology in primary care

We examined the feasibility of a low-cost, store-and-forward teledermatology service for general practitioners (GPs) in regional Queensland. Digital pictures and a brief case history were transmitted by email. A service coordinator carried out quality control checks and then forwarded these email messages to a consultant dermatologist. On receiving a clinical response from the dermatologist, the service coordinator returned the message to the referring GP. The aim was to provide advice to rural GPs within one working day. Over six months, 63 referrals were processed by the teledermatology service, covering a wide range of dermatological conditions. In the majority of cases the referring doctors were able to treat the condition after receipt of email advice from the dermatologist; however, in 10 cases (16%) additional images or biopsy results were requested because image quality was inadequate. The average time between a referral being received and clinical advice being provided to the referring GPs was 46 hours. The number of referrals in the present study, 1.05 per month per site, was similar to that reported in other primary care studies. While the use of low-cost digital cameras and public email is feasible, there may be other issues, for example remuneration, which will militate against the widespread introduction of primary care teledermatology in Australia.

Substitution rates of video consultations for traditional consultations at a tertiary public hospital

Using a case study approach, we conducted a retrospective review of 12 months of outpatient activity at the Princess Alexandra Hospital (PAH) in Brisbane, Australia. From our dataset we calculated two variables – the telehealth-eligible substitution rate and the overall telehealth substitution rate. Telehealth eligibility is specialty-specific and is based on clinical and geographical constraints. During the study period there were video consultations ( N = 1088) and traditional consultations ( N = 41,951). The telehealth-eligible and overall substitution rates were 17.5% and 2.5%, respectively. The overall telehealth substitution rate is substantially lower than the telehealth-eligible substitution rate. This is due to the majority of patients being from local catchment areas which are currently ineligible for video consultations at the PAH. The highest observed overall telehealth substitution rate was for the radiosurgery which had telehealth activity as a reportable key performance indicator since inception of the service, which may have contributed to the relatively high rate. In-home video consultations with patients who reside in metropolitan areas are needed to substantially increase the rate of telehealth substitution.

The Utility of Digital Clinical Photographs in Dermatopathology

Background and Objective:

Technological improvements have helped digital cameras become widely available and inexpensive. Dermatopathologic diagnosis is often aided by clinical information. The purpose of this study was to determine whether submitting a digital image along with a skin biopsy provides additional helpful information to the dermatopathologist.

Methods:

Digital pictures were taken of the lesion being biopsied and were submitted along with routine paper work to the dermatopathologists. The dermatopathologists interpreted the skin biopsy as usual without viewing the digital image, and then later viewed the submitted picture. The dermatopathologists evaluated the help provided by the image.

Results:

A clinical digital image was helpful in confirming the initial diagnosis and narrowing down the differential diagnosis ( p < 0.001). Including pictures did not change the diagnosis, result in an increase in the differential diagnosis, or result in fewer or additional step sections being performed. Digital imaging of inflammatory disorders was felt to be good help in 43 % of the biopsies and narrowed down the differential diagnosis in 31%.

Conclusion:

In certain cases the inclusion of a digital image may help a dermatopathologist. Digital imaging was found to be most helpful in evaluation of inflammatory disorders.

Teledermatology in New Zealand

Background:

Teledermatology is the delivery of specialist dermatological services at a distance. It has become possible because of technological advances in digital imaging and telecommunications. Consultations may be “interactive” using video-conferencing equipment or “store-and-forward” using prerecorded text and images. The best method to deliver teledermatology services is unknown.

Objective:

Studies were designed to determine (a) if it was possible to diagnose and manage skin diseases using video-conferencing equipment, (b) if teledermatology was acceptable to patients and medical practitioners, and (c) whether it offered any economic advantages. We have also compared interactive and store-and-forward techniques.

Method:

The trials were conducted in collaboration with the Institute of Telemedicine & Telecare, Queen's University, Belfast, as part of the UK Teledermatology Trials.

Remits:

The trials have involved more than 300 teledermatology consultations. Having established that a diagnosis can be made in more than two-thirds of the cases, the majority of video consultations have resulted in satisfactory management, with only small numbers of patients requiring face-to-face review. Teledermatology is generally popular with patients and can save them considerable time and money. Routine clinics continue in three centers. We have found that effective store-and-forward teledermatology requires very good images and comprehensive historical referral data.

Stakeholders’ experience of teledermatology in a nurse-led community clinic: a case study

Dermatology is regarded as especially suitable for the application of telemedicine because it relies to a large extent on visual information for diagnosis and holds promise as an alternative means of delivering healthcare. Interest in teledermatology has come at a time when there is an increased demand for dermatological services and has been advocated as a mode of delivery that may diminish inequalities in the provision of an overstretched service and improve access to dermatological care. A qualitative case study based on interviews and observations was undertaken to explore the perceptions of stakeholders (nurses, patients, GPs, consultants) when interacting with a nurse-led teledermatology service in primary care. The study found that the delineation of roles and changing professional boundaries were important issues for stakeholders. It has provided further evidence that teledermatology is more than images and diagnostics.

Opportunity cost of the dermatologist's consulting time in the economic evaluation of teledermatology

Introduction This study, through a systematic review and meta-analysis, has sought to demonstrate that the opportunity cost is a value to take into account in studies of economic cost in telemedicine, illustrated through the time of the dermatologist's consultation in teledermatology and traditional consultation. Methods Economic evaluation studies have been identified that compare teledermatology and traditional dermatological consultation during the period 1998-2015. We carried out a meta-analysis considering the work cost and the dermatologist's consultation time, analysing their differences. The opportunity cost represented by these differences in the dermatological remote consultation time was subsequently calculated based on the design of a cost/time variable. Results It was not possible to meta-analyse the cost of the dermatologist's consultation due to insufficient standardized complete data. It was possible to carry out a meta-analysis of the consultation time, and three articles were selected (2945 patients). Teledermatology accounts for more time (7.54 min) than conventional consultation ( p < 0.00001) and this difference is an opportunity cost of teledermatology of €29.25 per each remote consultation, with a unitary factor cost/time of 3.88€/minute. Conclusions There is no unanimity in the literature regarding which of the two procedures is cheaper; further studies with the necessary standardized variables are required. In this meta-analysis, teledermatology takes more time than a conventional dermatology consultation, which leads to an opportunity cost, increasing the total cost of consultation. The opportunity cost is a value that should be included in an analysis of economic costs, in the context of an economic assessment, when we evaluate a health activity.

Interobserver reliability of teledermatology across all Fitzpatrick skin types

Introduction Demand for dermatologic services in safety net hospitals, which disproportionately serve patients with darker coloured skin, is growing. Teledermatology has the potential to increase access and improve outcomes, but studies have yet to demonstrate the reliability of teledermatology for all Fitzpatrick skin types. Methods We assessed the reliability of teledermatologists' diagnoses and management recommendations for store-and-forward teledermatology in patients with lightly pigmented (Fitzpatrick skin types I-III) versus darkly pigmented (Fitzpatrick skin types IV-VI) skin, when compared to in-person diagnosis and management decisions. This prospective study enrolled 232 adult patients, presenting with new, visible skin complaints in a Los Angeles county dermatology clinic. Forty-seven percent of patients were Fitzpatrick skin types I-III, and 53% were Fitzpatrick skin types IV-VI. Results Percent concordance for the identical primary diagnosis was 53.2% in lighter (Fitzpatrick I-III) skin types and 56.0% in darker (Fitzpatrick IV-VI) skin types. There was no statistically significant difference in concordance rates between lighter and darker skin types for primary diagnosis. Concordance rates for diagnostic testing, clinic-based therapy, and treatments were similar in both groups of Fitzpatrick skin types. Discussion These results suggest that teledermatology is reliable for the diagnosis and management of patients with all Fitzpatrick skin types.

A Simulation Model for Analysing Patient Activity in Dermatology

We developed a general model to assess patient activity within the primary and secondary health-care sectors following a dermatology outpatient consultation. Based on observed variables from the UK teledermatology trial, the model showed that up to 11 doctor-patient interactions occurred before a patient was ultimately discharged from care. In a cohort of 1000 patients, the average number of health-care visits was 2.4 (range 1–11). Simulation analysis suggested that the most important parameter affecting the total number of doctor-patient interactions is patient discharge from care following the initial consultation. This implies that resources should be concentrated in this area. The introduction of teledermatology (either realtime or store and forward) changes the values of the model parameters. The model provides a quantitative tool for planning the future provision of dermatology health-care.

Assessment of Utilization and Cost-Effectiveness of Telemedicine Program in Western Regions of China: A 12-Year Study of 249 Hospitals Across 112 Cities

BACKGROUND

The imbalance in healthcare between urban and rural areas is still a problem in China. In recent decades, China has aimed to develop telemedicine. We assessed the implementation, utilization, and cost-effectiveness of a large telemedicine program across western China.

MATERIALS AND METHODS

In 2002-2013, a government-sponsored major telemedicine program was established by West China Hospital of Sichuan University (hub), covering 249 spoke hospitals in 112 cities throughout western China and in 40 medical expertise areas. We analyzed the cross-sectional data from 11,987 consultations conducted at West China Hospital using the telemedicine network over a 12-year period. The types of diseases as well as the diagnosis and treatment changes were assessed. We also performed a cost-savings analysis and a one-way sensitivity analysis.

RESULTS

Of the 11,987 teleconsultations, we noted that neoplasms (19.4%), injuries (13.9%), and circulatory diseases (10.3%) were the three most common diagnoses. Teleconsultations resulted in a change of diagnosis in 4,772 (39.8%) patients, and 3,707 (77.7%) of them underwent major diagnosis changes. Moreover, it led to a change of treatment in 6,591 (55.0%) patients, including 3,677 (55.8%) changes not linked to diagnosis changes. The telemedicine network resulted in an estimated net saving of $2,364,525 (if the patients traveled to the hub) or $3,759,014 (if the specialists traveled to the spoke hospitals).

CONCLUSIONS

The introduction of telemedicine in China, linking highly specialized major hospitals (hub) with hundreds of small rural hospitals (spoke), can greatly improve the quality, efficiency, and cost-effectiveness of healthcare delivery and utilization. This new Internet-based healthcare model should be utilized more widely in developing countries.

E-consulting in a medical specialist setting: Medicine of the future?

OBJECTIVE

Today's technology provides new ways of consulting between patients and medical specialists in health care, such as videoconferencing and web-messaging. In this systematic review we assessed the effects of e-consulting between medical specialists and patients.

METHODS

We searched MEDLINE, EMBASE, Psychlit and Cochrane Library for randomized clinical trials assessing the use of e-consulting methods (videoconferencing (VC) or web-messaging (WM)), as compared to conventional care (face-to-face (FF) or telephone consultations (TC)) in a medical specialist setting. We extracted patient-related, physician-related, cost, time and follow-up outcomes.

RESULTS

We included 21 trials, of which 17 addressed VC compared to FF, two compared WM with FF, one VC with TC, and one WM with TC. Physicians appeared to prefer face-to-face consultations over videoconferencing. Patients appeared to be as satisfied with videoconferencing as with face-to-face contacts, but preferred videoconferencing and web-messaging over telephone consultations. Videoconferencing was more expensive regarding equipment, but saved patient-related costs in terms of time, transportation, and missed work. Variable results were found for consult time and follow-up visits.

CONCLUSIONS AND PRACTICE IMPLICATIONS

We cautiously conclude that e-consulting seems a feasible alternative to medical specialists' face-to-face follow-up or telephone appointments, but may be less suitable for initial consultations requiring physical examination.

Impact of Chest Pain Protocol with Access to Telemedicine on Implementation of Pharmacoinvasive Strategy in a Private Hospital Network

BACKGROUND

Brazilian registries have shown a gap between evidence-based therapies and real treatments. We aim to compare the use of the pharmacoinvasive strategy and mortality in patients with ST elevation myocardial infarction (STEMI) transferred pre- and post-chest pain protocol with access to telemedicine (CPPT) in a private hospital network.

MATERIALS AND METHODS

A CPPT was implemented in 22 private emergency departments in 2012. Emergency physicians and nurses of all facilities were trained to disseminate the information to comply with a chest pain protocol focusing on reperfusion therapy (pharmacoinvasive strategy) for STEMI. To conduct clinical discussions using telemedicine, a cardiologist from a reference hospital in cardiology (RHC) was available 24 h/day, 7 days/week. Using the database of all consecutive admissions, we compared the data of patients with STEMI transferred to the RHC in 2011 (pre-CPPT) and 2013-2014 (post-CPPT).

RESULTS

We included 376 patients (113 pre-CPPT and 263 post-CPPT) with STEMI. All patients admitted in the RHC were transferred from the 22 emergency departments. Comparing pre-CPPT and post-CPPT, we did not find differences regarding age, gender, hypertension, dyslipidemia, diabetes, smoking, previous myocardial infarction, or Killip classification. However, the use of CPPT was associated with a greater use of pharmacoinvasive strategy (55.8% versus 38%; p = 0.002) and a trend toward lower in-hospital mortality (3% versus 8%; p = 0.06).

CONCLUSIONS

The implementation of a CPPT was associated with a significant increase in the use of pharmacoinvasive strategy in patients with STEMI and a trend toward reduced in-hospital mortality in a private hospital network.

Teledermatology

This article provides an overview of teledermatology with an emphasis on the evidence most relevant to referring clinicians, who are often primary care clinicians. Discussion includes the different modalities used for teledermatology and their diagnostic reliability, diagnostic accuracy, impact on in-person dermatology visits, clinical outcomes, and user satisfaction.

Interactive telemedicine: effects on professional practice and health care outcomes

BACKGROUND

Telemedicine (TM) is the use of telecommunication systems to deliver health care at a distance. It has the potential to improve patient health outcomes, access to health care and reduce healthcare costs. As TM applications continue to evolve it is important to understand the impact TM might have on patients, healthcare professionals and the organisation of care.

OBJECTIVES

To assess the effectiveness, acceptability and costs of interactive TM as an alternative to, or in addition to, usual care (i.e. face-to-face care, or telephone consultation).

SEARCH METHODS

We searched the Effective Practice and Organisation of Care (EPOC) Group's specialised register, CENTRAL, MEDLINE, EMBASE, five other databases and two trials registers to June 2013, together with reference checking, citation searching, handsearching and contact with study authors to identify additional studies.

SELECTION CRITERIA

We considered randomised controlled trials of interactive TM that involved direct patient-provider interaction and was delivered in addition to, or substituting for, usual care compared with usual care alone, to participants with any clinical condition. We excluded telephone only interventions and wholly automatic self-management TM interventions.

DATA COLLECTION AND ANALYSIS

For each condition, we pooled outcome data that were sufficiently homogenous using fixed effect meta-analysis. We reported risk ratios (RR) and 95% confidence intervals (CI) for dichotomous outcomes, and mean differences (MD) for continuous outcomes.

MAIN RESULTS

We included 93 eligible trials (N = 22,047 participants), which evaluated the effectiveness of interactive TM delivered in addition to (32% of studies), as an alternative to (57% of studies), or partly substituted for usual care (11%) as compared to usual care alone.The included studies recruited patients with the following clinical conditions: cardiovascular disease (36), diabetes (21), respiratory conditions (9), mental health or substance abuse conditions (7), conditions requiring a specialist consultation (6), co morbidities (3), urogenital conditions (3), neurological injuries and conditions (2), gastrointestinal conditions (2), neonatal conditions requiring specialist care (2), solid organ transplantation (1), and cancer (1).Telemedicine provided remote monitoring (55 studies), or real-time video-conferencing (38 studies), which was used either alone or in combination. The main TM function varied depending on clinical condition, but fell typically into one of the following six categories, with some overlap: i) monitoring of a chronic condition to detect early signs of deterioration and prompt treatment and advice, (41); ii) provision of treatment or rehabilitation (12), for example the delivery of cognitive behavioural therapy, or incontinence training; iii) education and advice for self-management (23), for example nurses delivering education to patients with diabetes or providing support to parents of very low birth weight infants or to patients with home parenteral nutrition; iv) specialist consultations for diagnosis and treatment decisions (8), v) real-time assessment of clinical status, for example post-operative assessment after minor operation or follow-up after solid organ transplantation (8) vi), screening, for angina (1).The type of data transmitted by the patient, the frequency of data transfer, (e.g. telephone, e-mail, SMS) and frequency of interactions between patient and healthcare provider varied across studies, as did the type of healthcare provider/s and healthcare system involved in delivering the intervention.We found no difference between groups for all-cause mortality for patients with heart failure (16 studies; N = 5239; RR:0.89, 95% CI 0.76 to 1.03, P = 0.12; I(2) = 44%) (moderate to high certainty of evidence) at a median of six months follow-up. Admissions to hospital (11 studies; N = 4529) ranged from a decrease of 64% to an increase of 60% at median eight months follow-up (moderate certainty of evidence). We found some evidence of improved quality of life (five studies; N = 482; MD:-4.39, 95% CI -7.94 to -0.83; P < 0.02; I(2) = 0%) (moderate certainty of evidence) for those allocated to TM as compared with usual care at a median three months follow-up. In studies recruiting participants with diabetes (16 studies; N = 2768) we found lower glycated haemoglobin (HbA1c %) levels in those allocated to TM than in controls (MD -0.31, 95% CI -0.37 to -0.24; P < 0.00001; I(2)= 42%, P = 0.04) (high certainty of evidence) at a median of nine months follow-up. We found some evidence for a decrease in LDL (four studies, N = 1692; MD -12.45, 95% CI -14.23 to -10.68; P < 0.00001; I(2 =) 0%) (moderate certainty of evidence), and blood pressure (four studies, N = 1770: MD: SBP:-4.33, 95% CI -5.30 to -3.35, P < 0.00001; I(2) = 17%; DBP: -2.75 95% CI -3.28 to -2.22, P < 0.00001; I(2) = 45% (moderate certainty evidence), in TM as compared with usual care.Seven studies that recruited participants with different mental health and substance abuse problems, reported no differences in the effect of therapy delivered over video-conferencing, as compared to face-to-face delivery. Findings from the other studies were inconsistent; there was some evidence that monitoring via TM improved blood pressure control in participants with hypertension, and a few studies reported improved symptom scores for those with a respiratory condition. Studies recruiting participants requiring mental health services and those requiring specialist consultation for a dermatological condition reported no differences between groups.

AUTHORS' CONCLUSIONS

The findings in our review indicate that the use of TM in the management of heart failure appears to lead to similar health outcomes as face-to-face or telephone delivery of care; there is evidence that TM can improve the control of blood glucose in those with diabetes. The cost to a health service, and acceptability by patients and healthcare professionals, is not clear due to limited data reported for these outcomes. The effectiveness of TM may depend on a number of different factors, including those related to the study population e.g. the severity of the condition and the disease trajectory of the participants, the function of the intervention e.g., if it is used for monitoring a chronic condition, or to provide access to diagnostic services, as well as the healthcare provider and healthcare system involved in delivering the intervention.

We considered randomised controlled trials of interactive TM that involved direct patient-provider interaction and was delivered in addition to, or substituting for, usual care compared with usual care alone, to participants with any clinical condition. We excluded telephone only interventions and wholly automatic self-management TM interventions.

DATA COLLECTION AND ANALYSIS

For each condition, we pooled outcome data that were sufficiently homogenous using fixed effect meta-analysis. We reported risk ratios (RR) and 95% confidence intervals (CI) for dichotomous outcomes, and mean differences (MD) for continuous outcomes.

MAIN RESULTS

We included 93 eligible trials (N = 22,047 participants), which evaluated the effectiveness of interactive TM delivered in addition to (32% of studies), as an alternative to (57% of studies), or partly substituted for usual care (11%) as compared to usual care alone.The included studies recruited patients with the following clinical conditions: cardiovascular disease (36), diabetes (21), respiratory conditions (9), mental health or substance abuse conditions (7), conditions requiring a specialist consultation (6), co morbidities (3), urogenital conditions (3), neurological injuries and conditions (2), gastrointestinal conditions (2), neonatal conditions requiring specialist care (2), solid organ transplantation (1), and cancer (1).Telemedicine provided remote monitoring (55 studies), or real-time video-conferencing (38 studies), which was used either alone or in combination. The main TM function varied depending on clinical condition, but fell typically into one of the following six categories, with some overlap: i) monitoring of a chronic condition to detect early signs of deterioration and prompt treatment and advice, (41); ii) provision of treatment or rehabilitation (12), for example the delivery of cognitive behavioural therapy, or incontinence training; iii) education and advice for self-management (23), for example nurses delivering education to patients with diabetes or providing support to parents of very low birth weight infants or to patients with home parenteral nutrition; iv) specialist consultations for diagnosis and treatment decisions (8), v) real-time assessment of clinical status, for example post-operative assessment after minor operation or follow-up after solid organ transplantation (8) vi), screening, for angina (1).The type of data transmitted by the patient, the frequency of data transfer, (e.g. telephone, e-mail, SMS) and frequency of interactions between patient and healthcare provider varied across studies, as did the type of healthcare provider/s and healthcare system involved in delivering the intervention.We found no difference between groups for all-cause mortality for patients with heart failure (16 studies; N = 5239; RR:0.89, 95% CI 0.76 to 1.03, P = 0.12; I(2) = 44%) (moderate to high certainty of evidence) at a median of six months follow-up. Admissions to hospital (11 studies; N = 4529) ranged from a decrease of 64% to an increase of 60% at median eight months follow-up (moderate certainty of evidence). We found some evidence of improved quality of life (five studies; N = 482; MD:-4.39, 95% CI -7.94 to -0.83; P < 0.02; I(2) = 0%) (moderate certainty of evidence) for those allocated to TM as compared with usual care at a median three months follow-up. In studies recruiting participants with diabetes (16 studies; N = 2768) we found lower glycated haemoglobin (HbA1c %) levels in those allocated to TM than in controls (MD -0.31, 95% CI -0.37 to -0.24; P < 0.00001; I(2)= 42%, P = 0.04) (high certainty of evidence) at a median of nine months follow-up. We found some evidence for a decrease in LDL (four studies, N = 1692; MD -12.45, 95% CI -14.23 to -10.68; P < 0.00001; I(2 =) 0%) (moderate certainty of evidence), and blood pressure (four studies, N = 1770: MD: SBP:-4.33, 95% CI -5.30 to -3.35, P < 0.00001; I(2) = 17%; DBP: -2.75 95% CI -3.28 to -2.22, P < 0.00001; I(2) = 45% (moderate certainty evidence), in TM as compared with usual care.Seven studies that recruited participants with different mental health and substance abuse problems, reported no differences in the effect of therapy delivered over video-conferencing, as compared to face-to-face delivery. Findings from the other studies were inconsistent; there was some evidence that monitoring via TM improved blood pressure control in participants with hypertension, and a few studies reported improved symptom scores for those with a respiratory condition. Studies recruiting participants requiring mental health services and those requiring specialist consultation for a dermatological condition reported no differences between groups.

AUTHORS' CONCLUSIONS

The findings in our review indicate that the use of TM in the management of heart failure appears to lead to similar health outcomes as face-to-face or telephone delivery of care; there is evidence that TM can improve the control of blood glucose in those with diabetes. The cost to a health service, and acceptability by patients and healthcare professionals, is not clear due to limited data reported for these outcomes. The effectiveness of TM may depend on a number of different factors, including those related to the study population e.g. the severity of the condition and the disease trajectory of the participants, the function of the intervention e.g., if it is used for monitoring a chronic condition, or to provide access to diagnostic services, as well as the healthcare provider and healthcare system involved in delivering the intervention.

Does teledermatology reduces secondary care referrals and is it acceptable to patients and doctors?: a service evaluation

RATIONALE, AIMS AND OBJECTIVES

Referrals to dermatology for skin lesions is increasing. Teledermatology allows patients to obtain specialist advice remotely. The aim of this study is to assess if teledermatology reduces secondary care dermatology referrals and evaluate its acceptability to patients and clinicians.

METHODS

A 24-month before and after comparative evaluation of a teledermatology service was undertaken involving four non-randomly allocated intervention practices and 18 control practices. Referral data for 12 months before and after the introduction of teledermatology was compared in intervention and control practices. Patient questionnaires explored their satisfaction and structured user dialogues explored the usefulness and benefits to clinicians. Time series analysis, adjusted for age and sex, was undertaken to assess the impact on secondary care referrals.

RESULTS

There were 195 Telederm referrals during the 12-month pilot period. Seborrhoeic keratosis was the commonest diagnosis. No action was required in 86 patients. Urgent referral to secondary care was recommended in 64 patients and routine referral in 19. The difference in referral rate before and after was +2.11 referrals per 1000 practice population in the teledermatology group and +1.39 in the control group. This was statistically significant in the adjusted, but not unadjusted, analysis. There was a 14% response rate for the questionnaire. The service was very popular with patients and clinicians. Clinicians highlighted the significant educational benefit.

CONCLUSION

We did not find any evidence that teledermatology reduced secondary care referral rates but in this small pilot, we found that it increased referrals in the short term. It was very popular among patients and clinicians, especially for its educational value.

Waikato Teledermatology: a pilot project for improving access in New Zealand

Introduction

Teledermatology can improve access to specialist dermatological advice. We describe a retrospective review of the first 12 months of Waikato Teledermatology (WT), a low-cost, secure, website-based, store-and-forward teledermatology network using the Collegium Telemedicus platform.

Methods

We determined specialist response time, referral metrics, patient diagnosis and progress reports from the network’s database. The programme’s value was evaluated by post-pilot online surveys of referrers and specialist dermatologists.

Results

WT was used by 31 referring doctors for 309 consultations with four dermatologists between July 2013 and June 2014. Mean and median specialist response time was 2.07 hours (range: 0.13–5.64 hours). The researchers categorized the referrals as tumours (56.8%) and rashes (43.2%), including inflammatory dermatoses (51.9%), infection (18.1%), uncertain (16.5%), miscellaneous (7.5%), and of environmental origin (6%). Thirty tumours were biopsied, including nine melanomas and three basal cell carcinomas. A total of 158 progress reports and 35 survey responses were received. Reported advantages included decreased delay, improved accuracy of diagnosis and treatment compared to that made without specialist input, decreased unnecessary procedures such as biopsies of undiagnosed conditions, and increased appropriate referrals for face-to-face assessment, thus leading to cost savings for the patient and the health care system. The major disadvantages were the time burden for clinicians to complete consultations, the lack of integration with the patients’ usual electronic medical record and absence of funding.

Discussion

WT proved an effective and acceptable approach to improving patient access to dermatologic services.

The association between general practitioner participation in joint teleconsultations and rates of referral: a discrete choice experiment

Background

Joint consultations – such as teleconsultations – provide opportunities for continuing education of general practitioners (GPs). It has been reported this form of interactive case-based learning may lead to fewer GP referrals, yet these studies have relied on expert opinion and simple frequencies, without accounting for other factors known to influence referrals. We use a survey-based discrete choice experiment of GPs’ referral preferences to estimate how referral rates are associated with participation in joint teleconsultations, explicitly controlling for a number of potentially confounding variables.

Methods

We distributed questionnaires at two meetings of the Portuguese Association of General Practice. GPs were presented with descriptions of patients with dermatological lesions and asked whether they would refer based on the waiting time, the distance to appointment, and pressure from patients for a referral. We analysed GPs’ responses to multiple combinations of these factors, coupled with information on GP and practice characteristics, using a binary logit model. We estimated the probabilities of referral of different lesions using marginal effects.

Results

Questionnaires were returned by 44 GPs, giving a total of 721 referral choices. The average referral rate for the 11 GPs (25%) who had participated in teleconsultations was 68.1% (range 53-88%), compared to 74.4% (range 47-100%) for the remaining physicians. Participation in teleconsultations was associated with reductions in the probabilities of referral of 17.6% for patients presenting with keratosis (p = 0.02), 42.3% for psoriasis (p < 0.001), 8.4% for melanoma (p = 0.14), and 5.4% for naevus (p = 0.19).

Conclusions

The results indicate that GP participation in teleconsultations is associated with overall reductions in referral rates and in variation across GPs, and that these effects are robust to the inclusion of other factors known to influence referrals. The reduction in range, coupled with different effects for different clinical presentations, may suggest an educational effect. However, more research is needed to establish whether there are causal relationships between participation in teleconsultations, continuing education, and referral rates.
