Trial of low-cost teledermatology in primary care

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

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

A qualitative descriptive study of a novel nurse-led skin cancer screening model in rural Australia

Background

People residing in rural areas have higher rates of skin cancer and face barriers to accessing care. Models of skin cancer care addressing the specific needs of rural communities and overcoming specific challenges are required, but literature is scarce. This study aimed to describe the elements of a nurse-led skin cancer model in rural Victoria using qualitative methodology and programme logic to inform implementation and ongoing sustainability.

Methods

Qualitative descriptive design. Semi-structured interviews were conducted with key stakeholders involved in the skin cancer model, namely health service executive management, clinical staff, and administration staff. Interviews were audio-recorded and transcribed verbatim. Transcripts were thematically analysed independently by two researchers before themes were compared and refined. A programme logic model was developed to organise themes into contextual elements, inputs, activities and anticipated outcomes; it was also used as a visual tool to aid discussions with key stakeholders. Member checking of the logic model occurred to verify interpretation. This programme logic model will be refined throughout the implementation phase, and again after three years of service delivery.

Results

Eight stakeholders participated in interviews. Thematic analysis identified three major themes: the influence of the local rural context, the elements of the model, and “making it happen’. These major themes and accompanying sub-themes were mapped to the programme logic model by contextual elements (rural locale, health service access barriers, burden of disease), key inputs (promotion, human resources including appropriate nurse training and leadership) and ‘making it happen’ (governance including referral pathways, flexible and sustained funding, and partnerships). The anticipated outcomes identified include skin cancer care delivered locally, timely access, career development for nurses, and decreased skin cancer burden.

Conclusion

An initiative that is place-based and community driven in response to consumer demand addresses key system barriers to earlier detection of skin cancers. It is anticipated to result in flow-on reductions in skin cancer disease burden. Programme logic was useful to both describe the initiative and as a visual tool for discussions, with the potential to inform wider health service efforts to address system barriers and bottlenecks.

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.

Telehealth interventions for reducing waiting lists and waiting times for specialist outpatient services: A scoping review

We undertook a scoping review of the published literature to identify and summarise key findings on the telehealth interventions that influence waiting times or waiting lists for specialist outpatient services. Searches were conducted to identify relevant articles. Articles were included if the telehealth intervention restructured or made the referral process more efficient. We excluded studies that simply increased capacity. Two categories of interventions were identified - electronic consultations and image-based triage. Electronic consultations are asynchronous, text-based provider-to-provider consultations. Electronic consultations have been reported to obviate the need for face-to-face appointments between the patient and the specialist in between 34-92% of cases. However, it is often reported that electronic consultations are appropriate in less than 10% of referrals for outpatient care. Image-based triage has been used successfully to reduce unnecessary or inappropriate referrals and was used most often in dermatology, ophthalmology and otolaryngology (ENT). Reported reduction rates for face-to-face appointments by specialty were: dermatology 38-88%, ophthalmology 16-48% and ENT 89%. Image-based triage can be twice as effective as non-image based triage in reducing unnecessary appointments. Telehealth interventions can effectively be used to reduce waiting lists and improve the coordination of specialist services, and should be considered in conjunction with clinical requirements.

Real-time mobile teledermoscopy for skin cancer screening targeting an agricultural population: an experiment on 289 patients in France

BACKGROUND

The incidence of skin cancer has reached epidemic proportions in the white population and is significantly elevated in agricultural populations, who are exposed to ultraviolet radiation during their professional activities. In 2014, the Agricultural Social Insurance Mutual Benefit Fund (MSA) offered its customers who work in agriculture and live in rural areas with reduced access to dermatologists the ability to participate in a 1-day teledermoscopic (TDS) screening event.

OBJECTIVE

This study's aim was to assess the feasibility of real-time mobile TDS triage of a large number of agricultural workers by trained medical officers and occupational physicians.

METHODS

Fifteen TDS screening centres were located in different areas of France. Individuals older than 18 years who worked in agriculture and lived in rural area near a TDS screening centre were invited to participate in a 1-day screening event and were examined by an MSA physician. In cases of suspicious skin lesions, clinical and dermoscopic images were obtained and transferred immediately to four dermatologists who were simultaneously present at the tele-platform for diagnosis and decision-making. Low-quality images were retaken.

RESULTS

Two-hundred eighty-nine patients underwent skin cancer screening. Among 199 patients (69%), 390 suspicious lesions were identified and generated 412 pictures. All lesions were analysed by dermatologists. For 105 patients (53%), no follow-up was required. Seventeen patients were referred to local dermatologists for rapid examination, including 12 cases of suspected malignant melanocytic lesions. Among the 12 patients with suspected melanoma, face-to-face visits were conducted within 10 days for 11 of them, and 1 case of melanoma was confirmed by histopathology.

CONCLUSIONS

Our study suggests that teledermoscopy performed in the context of occupational medicine and targeted to agricultural populations is feasible and could be useful for improving skin cancer screening in at-risk populations while avoiding face-to-face examinations by a dermatologist in 53% of cases.

What is the evidence on interventions to manage referral from primary to specialist non-emergency care? A systematic review and logic model synthesis

Background

Demand management describes any method used to monitor, direct or regulate patient referrals. Several strategies have been developed to manage the referral of patients to secondary care, with interventions targeting primary care, specialist services, or infrastructure.

Objective

This research aimed to conduct an inclusive systematic review and logic model synthesis in order to better understand factors impacting on the effectiveness of interventions targeting referral between primary and secondary medical health care.

Design

The approach combined systematic review with logic modelling synthesis techniques to develop an evidence-based framework of factors influencing the pathway between interventions and system-wide changes.

Setting

Primary health care.

Main outcome measures

Referral from primary to secondary care.

Review methods

Systematic searches were undertaken to identify recent, relevant studies. Quality of individual studies was appraised, with consideration of overall strength of evidence. A narrative synthesis and logic model summary of the data was completed.

Results

From a database of 8327 unique papers, 290 were included in the review. The intervention studies were grouped into four categories of education interventions (n = 50); process change interventions (n = 49); system change interventions (n = 38); and patient-focused interventions (n = 3). Effectiveness was assessed variously in these papers; however, there was a gap regarding the mechanisms whereby these interventions lead to demand management impacts. The findings suggest that, although individual-level interventions may be popular, the stronger evidence relates only to peer-review and feedback interventions. Process change interventions appeared to be more effective when the change resulted in the specialist being provided with more or better quality information about the patient. System changes including the community provision of specialist services by general practitioners, outreach provision by specialists and the return of inappropriate referrals appeared to have evidence of effect. The pathway whereby interventions might lead to service-wide impact was complex, with multiple factors potentially acting as barriers or facilitators to the change process. Factors related, first, to the doctor (including knowledge, attitudes and beliefs, and previous experiences of a service), second, to the patient (including condition and social factors) and, third, to the influence of the doctor–patient relationship. We also identified a number of potentially influential factors at a local level, such as perceived waiting times and the availability of a specialist. These elements are key factors in the pathway between an intervention and intended demand management outcomes influencing both applicability and effectiveness.

Conclusions

The findings highlight the complexity of the referral process and multiple elements that will impact on intervention outcomes and applicability to a local area. Any interventions seeking to change referral practice need to address factors relating to the individual practitioner, the patient and also the situation in which the referral is taking place. These conclusions apply especially to referral management in a UK context where this whole range of factors/issues lies well within the remit of the NHS. This work highlights that intermediate outcomes are important in the referral pathway. It is recommended that researchers include measure of these intermediate outcomes in their evaluation of intervention effectiveness in order to determine where blocks to or facilitators of system-wide impact may be occurring.

Feasibility and diagnostic accuracy of teledermatology in Swiss primary care: process analysis of a randomized controlled trial

RATIONALE, AIM AND OBJECTIVE

To test feasibility and diagnostic accuracy of dermatologist's feedback based on digital images of skin lesions collected in Swiss primary care.

METHODS

This was a process analysis of a randomized controlled trial, conducted in 2011/2012. 30 of 78 general practitioners (GPs) were randomized to an intervention, which included dermatologist's feedback on digital images of skin lesions. Feedback was categorized into four categories: (1) no further investigation; (2) clinical observation; (3) biopsy; and (4) other. Histologic findings were allocated to the same categories. Feasibility was measured in the perspective of GPs concerning technical handling and of dermatologists as proportion of images usable for feedback. Diagnostic accuracy was measured as proportion of malignant histology of the first three feedback groups. No long-term data was collected.

RESULTS

981 images of skin lesions were collected, two were not eligible due to low quality of images. The majority of GPs (77.8%) reported no problem with the procedure. 207 images were in feedback category 1, 353 in 2, 360 in 3 and 59 in 4. A total of 236 histologic tests were collected. Three cases in category 1 indicated malignancy (1 melanoma). 201 of category 3 received a biopsy, where in 91 (45.3%) malignancy was confirmed.

CONCLUSION

Teledermatology with digital images taken in primary care was feasible from a GP and from a specialist perspective. However, diagnostic appropriateness regarding avoidance of specialist care and possible missed skin cancer raises concerns. These results therefore question a promotion of teledermatology in clinical routine.

Referral interventions from primary to specialist care: a systematic review of international evidence

BACKGROUND

Demand management defines any method used to monitor, direct, or regulate patient referrals. Strategies have been developed to manage the referral of patients to secondary care, with interventions that target primary care, specialist services, or infrastructure.

AIM

To review the international evidence on interventions to manage referral from primary to specialist care.

DESIGN AND SETTING

Systematic review.

METHOD

Iterative, systematic searches of published and unpublished sources public health, health management, management, and grey literature databases from health care and other industries were undertaken to identify recent, relevant studies. A narrative synthesis of the data was completed to structure the evidence into groups of similar interventions.

RESULTS

The searches generated 8327 unique results, of which 140 studies were included. Interventions were grouped into four intervention categories: GP education (n = 50); process change (n = 49); system change (n = 38); and patient-focused (n = 3). It is clear that there is no 'magic bullet' to managing demand for secondary care services: although some groups of interventions may have greater potential for development, given the existing evidence that they can be effective in specific contexts.

CONCLUSIONS

To tackle demand management of primary care services, the focus cannot be on primary care alone; a whole-systems approach is needed because the introduction of interventions in primary care is often just the starting point of the referral process. In addition, more research is needed to develop and evaluate interventions that acknowledge the role of the patient in the referral decision.

Teleconsultation service to improve healthcare in rural areas: acceptance, organizational impact and appropriateness

Background

Nowadays, new organisational strategies should be indentified to improve primary care and its link with secondary care in terms of efficacy and timeliness of interventions thus preventing unnecessary hospital accesses and costs saving for the health system. The purpose of this study is to assess the effects of the use of teleconsultation by general practitioners in rural areas.

Methods

General practitioners were provided with a teleconsultation service from 2006 to 2008 to obtain a second opinion for cardiac, dermatological and diabetic problems. Access, acceptance, organisational impact, effectiveness and economics data were collected. Clinical and access data were systematically entered in a database while acceptance and organisational data were evaluated through ad hoc questionnaires.

Results

There were 957 teleconsultation contacts which resulted in access to health care services for 812 symptomatic patients living in 30 rural communities. Through the teleconsultation service, 48 general practitioners improved the appropriateness of primary care and the integration with secondary care. In fact, the level of concordance between intentions and consultations for cardiac problems was equal to 9%, in 86% of the cases the service entailed a saving of resources and in 5% of the cases, it improved the timeliness. 95% of the GPs considered the overall quality positively. For a future routine use of this service, trust in specialists, duration and workload of teleconsultations and reimbursement should be taken into account.

Conclusions

Managerial and policy implications emerged mainly related to the support to GPs in the provision of high quality primary care and decision-making processes in promoting similar services.

Asynchronous telehealth: a scoping review of analytic studies

BACKGROUND

Asynchronous telehealth captures clinically important digital samples (e.g., still images, video, audio, text files) and relevant data in one location and subsequently transmits these files for interpretation at a remote site by health professionals without requiring the simultaneous presence of the patient involved and his or her health care provider. Its utility in the health care system, however, still remains poorly defined. We conducted this scoping review to determine the impact of asynchronous telehealth on health outcomes, process of care, access to health services, and health resources.

METHODS

A search was performed up to December 2006 of MEDLINE, CINAHL, HealthSTAR, the Database of Abstracts of Reviews of Effectiveness, and The Cochrane Library. Studies were included if they contained original data on the use of asynchronous telehealth and were published in English in a peer-reviewed journal. Two independent reviewers screened all articles and extracted data, reaching consensus on the articles and data identified. Data were extracted on general study characteristics, clinical domain, technology, setting, category of outcome, and results. Study quality (internal validity) was assessed using the Jadad scale for randomized controlled trials and the Downs and Black index for non-randomized studies. Summary data were categorized by medical specialty and presented qualitatively.

RESULTS

The scoping review included 52 original studies from 238 citations identified; of these 52, almost half focused on the use of telehealth in dermatology. Included studies were characterized by diverse designs, interventions, and outcomes. Only 16 studies were judged to be of high quality. Most studies showed beneficial effects in terms of diagnostic accuracy, wait times, referral management, and satisfaction with services. Evidence on the impact of asynchronous telehealth on resource use in dermatology suggests a reduction in the number of, or avoidance of, in-person visits. Reports from other clinical domains also described the avoidance of unnecessary transfer of patients.

CONCLUSIONS

A significant portion of the asynchronous telehealth literature involves its use in dermatology. Although the quality of many original studies remains poor, at least within dermatology, there is consistent evidence suggesting that asynchronous telehealth could lead to shorter wait times, fewer unnecessary referrals, high levels of patient and provider satisfaction, and equivalent (or better) diagnostic accuracy when compared with face-to-face consultations. With the exception of a few studies in pediatric asthma, the impact of this intervention on individual health outcomes remains unknown.

Maturity of teledermatology evaluation research: a systematic literature review

BACKGROUND

There is a growing interest in teledermatology in today's clinical practice, but the maturity of the evaluation research of this technology is still unclear.

OBJECTIVES

This systematic review describes the maturity of teledermatology evaluation research over time and explores what kind of teledermatology outcome measures have been evaluated.

METHODS

Systematic review of literature found in Medline database (1966 up to April 2006). A telemedicine evaluation strategy consisting of four consecutive research phases (parallel to drug and diagnostics evaluation research) extended with a fifth postimplementation phase was used to classify all included studies by two independent reviewers. In addition, main characteristics (store-and-forward or real-time, study design, outcome measures) were registered.

RESULTS

Three hundred and forty-five papers were systematically selected from Medline, and 244 papers were excluded. For two randomized controlled trials (RCTs), multiple papers in phase III were found. After correcting for this, 99 studies remained included (11 phase I, 72 phase II, two phase III, six phase IV, eight postimplementation phase). The number of phase II studies is the largest and still growing, while other phases are much less represented. Diagnostic accuracy was the most often used outcome measure and was found in phase I, II and IV. Store-and-forward teledermatology has been evaluated more since 2001, but most phase IV studies (RCTs, including cost aspects) are on real-time teledermatology.

CONCLUSIONS

Most teledermatology evaluation studies are classified as feasibility studies (phase II). The number of phase III and IV studies remains low through the years. Compared with other specialties in telemedicine (i.e. telesurgery, telepaediatrics), teledermatology seems to be a mature application. However, more evaluation studies with a focus on clinical outcomes such as preventable referrals or time to recovery are needed to prove that teledermatology indeed is a promising and cost-saving technology.

Análisis de los motivos de consulta y de su coste en la asistencia dermatológica en un centro de Atención Primaria

INTRODUCTION

The objective of the study was to the visits for esthetic reasons in an out-patient dermatology consultation and their cost and calculate the invoicing of these visits for a site other than the medical specialist consulted.

METHOD

Prospective study in an out-patient dermatology clinic for 12 random days in February 2005. Endpoints of age, gender, diagnosis, cost per visit, cryotherapy and electrocoagulation were collected. Patients were divided into 3 groups: request for esthetic treatment (A), request for dermatology visit (B) and did not come (C).

RESULTS

Group B was the largest, with 205 users (46 %), followed by C with 134/455 (29 %) and by A with 116/455 (25 %). In the latter group, the diagnoses were: seborrheic keratosis 39/455 (9 %), acrocordons 21/455 (5 %), remaining diagnoses (intradermal melanocytic nevi, cherry angioma, solar lentigos): 56/116 (11 %). The cost of these visits was 2,528. 8 euros in the 12 days analyzed and treatment of a subgroup of 85 patients (18.75 %) with cryotherapy or electrocoagulation increased it up to 5,043.80 euros. Estimated cost for one year would be 82,950 euros. Calculation of the invoicing for a non-public supplier site to the National Health Service would be: 8769.60 euros/month and 97,875 euros/year. If we add the treatments described, we go from 28,403.40 euros/month to 317,113.80 euros/year.

CONCLUSIONS

These data and daily experience should make us think about the ethical consequences (do all the patients have to wait the same time?) as well as legal and collective ones (what type of dermatology do we want to specialize in?).

Detection and management of pornography-seeking in an online clinical dermatology atlas

BACKGROUND

Increased use of an online educational archive of photographic dermatology case materials (DermAtlas) indicated unexpected pornography-seeking behavior and misuse.

OBJECTIVE

We sought to assess the extent of archive misuse.

METHODS

Web usage/request patterns were examined over a 6-month period for requests by anatomic site, diagnosis, and age group plus anatomic site. Free-text queries and referrals from external Web sites were reviewed.

RESULTS

Of 7800 images, 5.5% contain genital sites. Of all requests, 11% were for anatomic sites (37% genital sites); 62% were specified for diagnoses (12% genital sites). When age group and anatomic site were specified, the relative risk of a child being requested (vs adult) was 1.48 (95% confidence interval 1.44-1.53). Of 10000 free text queries, 12% retrieved images containing genital sites. Of all referrals, 14.3% originated from nonmedical (pornography/fetish) Web sites.

LIMITATIONS

Requests are mixed with legitimate queries.

CONCLUSION

Online photographic dermatology archives are vulnerable to misuse. Monitoring and intervention are necessary to preserve their availability and integrity.

Operational teledermatology in Broken Hill, rural Australia

From January 2001 to January 2002, Broken Hill, New South Wales, served as a trial site for teledermatology as one method of access to dermatologists. Fourteen participating general practitioners referred 46 patients making up 48 teledermatology cases. The mean diagnostic agreement between general practitioners and dermatologists was 35% and 50% for primary and differential diagnoses, respectively. Teledermatology patients formed 12% of the collectively referred dermatology patients (outpatients and teledermatology). In this project, high patient and general practitioner acceptability and positive medical outcomes confirm the value of rural teledermatology. However, this project also revealed unexpected barriers and pitfalls in the effective operation of rural teledermatology. Lack of education of participants, inertia among potential users and patient inconvenience are issues that may adversely affect the effective implementation of rural teledermatology.
