Teledermatology in Hong Kong: a cost-effective method to provide service to the elderly patients living in institutions

The relationship between e-health literacy and information technology acceptance, and the willingness to share personal and health information among pregnant women

BACKGROUND

Many factors may affect pregnant women's willingness to accept information (IT) technology and share their personal and health information. One of these factors is their e-health literacy level.

OBJECTIVE

To investigate the relationship between e-health literacy and IT acceptance, as well as the willingness of pregnant women to share their information.

METHODS

This survey was conducted among pregnant women visiting hospitals and private physicians' offices in Zahedan, Iran in 2019. Data were collected using a 4-part questionnaire with 66 questions. The data were analyzed using descriptive (frequency, percentage, mean and standard deviation) and inferential (Pearson correlation coefficient and linear regression) statistics.

RESULTS

The mean scores of electronic health literacy, information technology acceptance, and willingness of pregnant women to share personal and health information were 27.43 ± 5.82, 145.49 ± 25.72, and 19.16 ± 5.47, respectively. There was a significant relationship between IT acceptance and information sharing, which means that with increasing IT acceptance, people were more willing to share their information. Also, the results showed that with the decrease in economic well-being, the willingness to share personal and health information decreases.

CONCLUSION

This study showed that with the increase in e-health literacy of pregnant women, their IT acceptance grows. Increasing IT acceptance improves their willingness to share their information. Setting and updating information-sharing rules and security mechanisms with the participation of people can help reduce concerns and increase public trust. Healthcare policymakers can encourage the use of health IT in the prevention and treatment of diseases by providing relevant education and informing people.

The reliability of symptom assessment by telepsychiatry compared with face to face psychiatric interviews

INTRODUCTION

With the start of the COVID-19 pandemic, the various social distancing policies imposed have mandated psychiatrists to consider the option of using telepsychiatry as an alternative to face-to-face interview in Hong Kong. Limitations over sample size, methodology and information technology were found in previous studies and the reliability of symptoms assessment remained a concern.

AIM

To evaluate the reliability of assessment of psychiatric symptoms by telepsychiatry comparing with face-to-face psychiatric interview.

METHOD

This study recruited a sample of adult psychiatric patients in psychiatric wards in Queen Mary Hospital. Semi-structural interviews with the use of standardized psychiatric assessment scales were carried out in telepsychiatry and face-to-face interview respectively by two clinicians and the reliability of psychiatric symptoms elicited were assessed.

RESULTS

90 patients completed the assessments The inter-method reliability in Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Columbia Suicide Severity Rating Scale and Brief Psychiatric Rating Scale showed good agreement when compared with face-to-face interview.

CONCLUSION

Symptoms assessment by telepsychiatry is comparable to assessment conducted by face-to-face interview.

Innovation to enhance health in care homes and evaluation of tools for measuring outcomes of care: rapid evidence synthesis

Background

Flexible, integrated models of service delivery are being developed to meet the changing demands of an ageing population. To underpin the spread of innovative models of care across the NHS, summaries of the current research evidence are needed. This report focuses exclusively on care homes and reviews work in four specific areas, identified as key enablers for the NHS England vanguard programme.

Aim

To conduct a rapid synthesis of evidence relating to enhancing health in care homes across four key areas: technology, communication and engagement, workforce and evaluation.

Objectives

(1) To map the published literature on the uses, benefits and challenges of technology in care homes; flexible and innovative uses of the nursing and support workforce to benefit resident care; communication and engagement between care homes, communities and health-related organisations; and approaches to the evaluation of new models of care in care homes. (2) To conduct rapid, systematic syntheses of evidence to answer the following questions. Which technologies have a positive impact on resident health and well-being? How should care homes and the NHS communicate to enhance resident, family and staff outcomes and experiences? Which measurement tools have been validated for use in UK care homes? What is the evidence that staffing levels (i.e. ratio of registered nurses and support staff to residents or different levels of support staff) influence resident outcomes?

Data sources

Searches of MEDLINE, CINAHL, Science Citation Index, Cochrane Database of Systematic Reviews, DARE (Database of Abstracts of Reviews of Effects) and Index to Theses. Grey literature was sought via Google™ (Mountain View, CA, USA) and websites relevant to each individual search.

Design

Mapping review and rapid, systematic evidence syntheses.

Setting

Care homes with and without nursing in high-income countries.

Review methods

Published literature was mapped to a bespoke framework, and four linked rapid critical reviews of the available evidence were undertaken using systematic methods. Data were not suitable for meta-analysis, and are presented in narrative syntheses.

Results

Seven hundred and sixty-one studies were mapped across the four topic areas, and 65 studies were included in systematic rapid reviews. This work identified a paucity of large, high-quality research studies, particularly from the UK. The key findings include the following. (1) Technology: some of the most promising interventions appear to be games that promote physical activity and enhance mental health and well-being. (2) Communication and engagement: structured communication tools have been shown to enhance communication with health services and resident outcomes in US studies. No robust evidence was identified on care home engagement with communities. (3) Evaluation: 6 of the 65 measurement tools identified had been validated for use in UK care homes, two of which provide general assessments of care. The methodological quality of all six tools was assessed as poor. (4) Workforce: joint working within and beyond the care home and initiatives that focus on staff taking on new but specific care tasks appear to be associated with enhanced outcomes. Evidence for staff taking on traditional nursing tasks without qualification is limited, but promising.

Limitations

This review was restricted to English-language publications after the year 2000. The rapid methodology has facilitated a broad review in a short time period, but the possibility of omissions and errors cannot be excluded.

Conclusions

This review provides limited evidential support for some of the innovations in the NHS vanguard programme, and identifies key issues and gaps for future research and evaluation.

Future work

Future work should provide high-quality evidence, in particular experimental studies, economic evaluations and research sensitive to the UK context.

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 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.

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.

Telecommunications technologies used in dermatovenerology

It presents up-to-date data on the potential and level of development of information and telecommunications technologies in specialized dermatovenerological medical institutions.

A systematic review of economic analyses of telehealth services using real time video communication

Background

Telehealth is the delivery of health care at a distance, using information and communication technology. The major rationales for its introduction have been to decrease costs, improve efficiency and increase access in health care delivery. This systematic review assesses the economic value of one type of telehealth delivery - synchronous or real time video communication - rather than examining a heterogeneous range of delivery modes as has been the case with previous reviews in this area.

Methods

A systematic search was undertaken for economic analyses of the clinical use of telehealth, ending in June 2009. Studies with patient outcome data and a non-telehealth comparator were included. Cost analyses, non-comparative studies and those where patient satisfaction was the only health outcome were excluded.

Results

36 articles met the inclusion criteria. 22(61%) of the studies found telehealth to be less costly than the non-telehealth alternative, 11(31%) found greater costs and 3 (9%) gave the same or mixed results. 23 of the studies took the perspective of the health services, 12 were societal, and one was from the patient perspective. In three studies of telehealth to rural areas, the health services paid more for telehealth, but due to savings in patient travel, the societal perspective demonstrated cost savings. In regard to health outcomes, 12 (33%) of studies found improved health outcomes, 21 (58%) found outcomes were not significantly different, 2(6%) found that telehealth was less effective, and 1 (3%) found outcomes differed according to patient group. The organisational model of care was more important in determining the value of the service than the clinical discipline, the type of technology, or the date of the study.

Conclusion

Delivery of health services by real time video communication was cost-effective for home care and access to on-call hospital specialists, showed mixed results for rural service delivery, and was not cost-effective for local delivery of services between hospitals and primary care.

A systematic review of the key indicators for assessing telehomecare cost-effectiveness

Telehomecare is considered one of the most successful applications of telehealth. However, despite increasing evidence of telehomecare benefits, the diffusion of these services is still limited. Decision-makers need strong evidence in order to expand the development of telehomecare to various populations, regions, and health conditions. The objective of this review is to provide a basis for decision-making by identifying common indicators from the literature on telehomecare. A comprehensive review of the literature on the cost-effectiveness of telehomecare was conducted in specialized bibliographic databases. A total of 23 studies met the inclusion criteria. First, selected studies were analyzed to identify and classify the indicators that better addressed the cost-effectiveness impacts of telehomecare projects. Then, a synthesis of the evidence was done by exploring the relative cost-effectiveness of telehomecare applications. The analyses show that there is fair evidence of cost-effectiveness for many telehomecare applications. However, the heterogeneity among cost-effectiveness indicators in the applications reviewed and the methodological limitations of the studies impede the possibility of generalizing the findings. This suggests the need for a set of common indicators that could be applied for assessing the costeffectiveness of telehomecare projects. This review provides knowledge on the indicators available for assessing cost-effectiveness in telehomecare projects. It appears that the specific context in which the projects take place, meaning different patients, environments, technologies, and healthcare systems, should be taken into account when selecting indicators for assessing telehomecare cost-effectiveness.

Retrospective review of teledermatology in the Waikato, 1997-2002

We reviewed scheduled interactive teledermatology consultations from 1997 to 2002 between the Department of Dermatology of Health Waikato in Hamilton and remote sites at Taumarunui Hospital, Taupo Health Centre and the Ranolf Medical Centre, Rotorua, in New Zealand. Eighty-five per cent of 384 appointments were attended and most non-attendances were unexplained. The reason for consulting a dermatologist was inflammatory skin disease in 74% of cases, cutaneous infection in 10%, a skin lesion in 12% and no diagnosis was made in 4%. Follow ups were arranged for 41%, mainly by telemedicine (74%). Despite the apparent success of 75% of consultations and positive feedback from patients attending them, the service has not proved sustainable long-term. This is because of other priorities for the delivery of health care, lack of support by clinicians and administrators, and ongoing financial costs.

Concordância entre diagnósticos dermatológicos feitos presencialmente e por imagens digitais

FUNDAMENTOS - A teledermatologia é o uso de tecnologia de telecomunicação para fornecer cuidados de problemas cutâneos à distância. OBJETIVOS - Avaliar a concordância diagnóstica presencial e à distância com imagens de lesões cutâneas. MÉTODOS - Pacientes consecutivos referenciados (n = 100) ao serviço de dermatologia foram divididos em dois grupos: no Grupo 1 foram vistos ao vivo 20 pacientes por dois dermatologistas separadamente; no Grupo 2, as lesões de 80 pacientes foram fotografadas previamente à consulta presencial. A fotografia digital e as informações referentes à história clínica foram enviadas para outro dermatologista para diagnóstico. Foi avaliada a taxa de concordância diagnóstica entre os dois dermatologistas pelo teste. RESULTADOS - O Kappa presencial encontrado foi de 0,91 (n = 20), e o Kappa virtual foi de 0,66 (n = 80). A teledermatologia mostrou melhor resultado para avaliação de dermatoses classificadas como infecciosas/infestações (Kappa = 0,71) e para alteração dos anexos (Kappa = 0,69). CONCLUSÕES - A concordância à distância foi menor que a concordância presencial. Acredita-se que a teledermatologia não possa substituir a consulta médica convencional, mas possa ser opção para triagem de pacientes, diminuindo o custo do sistema público de saúde e o tempo de espera por atendimento médico especializado.

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.

Teledermatology research review

Teledermatology consultations can be performed using either store-and-forward or real-time technology. The best-studied aspect of teledermatology is diagnostic reliability, also known as diagnostic agreement. A good level of diagnostic reliability is achieved by dermatologists using both store-and-forward and real-time modalities and is comparable to that found between clinic-based examiners. Less information is available regarding diagnostic accuracy. Current data suggest that teledermatologists reviewing store-and-forward consults achieve accuracy comparable to that of clinic-based dermatologists. When store-and-forward consult systems are used, approximately one in four in-person clinic appointments are averted. Real-time consult systems avoid the need to schedule approximately one in two clinic visits. Store-and-forward technology results in timelier interventions for patients when compared to a conventional referral process. To date, surveys of both store-and-forward and real-time teledermatology consult modalities suggest that patients, referring clinicians, and dermatologists are all highly satisfied with teledermatology consults. Very little has been published about the economic impact of store-and-forward teledermatology, whereas several studies have evaluated real-time modalities. Teledermatology has ranged from a cost-saving strategy to an intervention that incurs greater costs than conventional care, depending on the health care setting and economic perspective. Future research focusing on diagnostic accuracy, clinical outcomes using clinical course or disease status as outcome measures, development of reliable and valid teledermatology-specific survey instruments, and economic analyses that assess cost-effectiveness will help guide future teledermatology program assessments and policy.

Telehealth for older patients: the Hong Kong experience

We studied the feasibility, acceptability and cost-effectiveness of using telemedicine to provide geriatric services to residents of nursing homes. A local 200-bed nursing home supported by the community geriatric assessment team (CGAT) participated in a one-year study, during which videoconferencing was used to replace conventional outreach or clinic-based geriatric care. The feasibility of telemedicine was evaluated by participating specialists in a total of 1001 consultations. Other outcome measures included productivity gains, utilization of hospital emergency and inpatient services, and user satisfaction. Telemedicine was adequate for patient care in 60-99% of cases in seven different disciplines. The CGAT was able serve more patients and see them earlier and more frequently. Telemedicine was cheaper than conventional care, and well accepted by health-care professionals as well as clients. Substantial savings were achieved in the study period through a 9% reduction in visits to the hospital emergency department and 11% fewer hospital bed-days. Telemedicine was a feasible means of care delivery to a nursing home and resulted in enhanced productivity and cost-savings. Linking more such institutions to care providers would further increase cost-effectiveness.
