Integrating telecare for chronic disease management in the community: what needs to be done?

Background

Telecare could greatly facilitate chronic disease management in the community, but despite government promotion and positive demonstrations its implementation has been limited. This study aimed to identify factors inhibiting the implementation and integration of telecare systems for chronic disease management in the community.

Methods

Large scale comparative study employing qualitative data collection techniques: semi-structured interviews with key informants, task-groups, and workshops; framework analysis of qualitative data informed by Normalization Process Theory. Drawn from telecare services in community and domestic settings in England and Scotland, 221 participants were included, consisting of health professionals and managers; patients and carers; social care professionals and managers; and service suppliers and manufacturers.

Results

Key barriers to telecare integration were uncertainties about coherent and sustainable service and business models; lack of coordination across social and primary care boundaries, lack of financial or other incentives to include telecare within primary care services; a lack of a sense of continuity with previous service provision and self-care work undertaken by patients; and general uncertainty about the adequacy of telecare systems. These problems led to poor integration of policy and practice.

Conclusion

Telecare services may offer a cost effective and safe form of care for some people living with chronic illness. Slow and uneven implementation and integration do not stem from problems of adoption. They result from incomplete understanding of the role of telecare systems and subsequent adaption and embeddedness to context, and uncertainties about the best way to develop, coordinate, and sustain services that assist with chronic disease management. Interventions are therefore needed that (i) reduce uncertainty about the ownership of implementation processes and that lock together health and social care agencies; and (ii) ensure user centred rather than biomedical/service-centred models of care.

Understanding patients' experiences of treatment burden in chronic heart failure using normalization process theory

PURPOSE

Our goal was to assess the burden associated with treatment among patients living with chronic heart failure and to determine whether Normalization Process Theory (NPT) is a useful framework to help describe the components of treatment burden in these patients.

METHODS

We performed a secondary analysis of qualitative interview data, using framework analysis, informed by NPT, to determine the components of patient "work." Participants were 47 patients with chronic heart failure managed in primary care in the United Kingdom who had participated in an earlier qualitative study about living with this condition. We identified and examined data that fell outside of the coding frame to determine if important concepts or ideas were being missed by using the chosen theoretical framework.

RESULTS

We were able to identify and describe components of treatment burden as distinct from illness burden using the framework. Treatment burden in chronic heart failure includes the work of developing an understanding of treatments, interacting with others to organize care, attending appointments, taking medications, enacting lifestyle measures, and appraising treatments. Factors that patients reported as increasing treatment burden included too many medications and appointments, barriers to accessing services, fragmented and poorly organized care, lack of continuity, and inadequate communication between health professionals. Patient "work" that fell outside of the coding frame was exclusively emotional or spiritual in nature.

CONCLUSIONS

We identified core components of treatment burden as reported by patients with chronic heart failure. The findings suggest that NPT is a theoretical framework that facilitates understanding of experiences of health care work at the individual, as well as the organizational, level. Although further exploration and patient endorsement are necessary, our findings lay the foundation for a new target for treatment and quality improvement efforts toward patient-centered care.

Exploring public perspectives on e-health: findings from two citizen juries

BACKGROUND

Interest and investment in e-health continue to grow world-wide, but there remains relatively little engagement with the public on this subject, despite calls for more public involvement in health-care planning.

DESIGN

This study used two modified citizen juries to explore barriers and facilitators to e-health implementation and the priorities for future e-health research from the perspective of health service users and lay representatives. Citizen juries bring together a group of people to deliberate over a specific issue. They are given information and invited to 'cross-examine' witnesses during the process.

RESULTS

Jurors were very keen for lay views to be included in e-health development and embraced the citizen jury approach. They agreed unanimously that e-health should be developed and thought it was in many ways inevitable. Although there was much enthusiasm for a health-care system which offered e-health as an option, there was as much concern about what it might mean for patients if implemented inappropriately. E-health was preferred as an enhancement rather than substitute for, existing services. Lack of universal access was seen as a potential barrier to implementation but problems such as lack of computer literacy were seen as a temporary issue. Participants emphasized that e-health research needed to demonstrate both clinical and economic benefits.

CONCLUSION

There was broad support from the citizen juries for the development of e-health, although participants stressed that e-health should enhance, rather than substitute, face-to-face services. One-day citizen juries proved a practical method of public engagement on this subject.

E-health: implementation and evaluation research in Scotland -- a scoping exercise

We searched the National Research Register (NRR) to identify funded research in Scotland (or in collaboration with a Scottish partner) in the area of implementation and evaluation of e-health services. A total of 61 research projects were identified which had been funded since 1 January 1995. These projects shared almost 7 million pound of funding (1 pound is $1.9 or 1.3 euro), the main funding sources being the Scottish Government and the European Union. Based on the projects reviewed, the majority of e-health research in Scotland was being conducted within the communication systems domain. Most of the research was being conducted at a single centre: only 14 studies (23%) were multisite. Future collaboration between these researchers, involving larger scale funding bids, may increase the quantity of e-health implementation and evaluation research.

Understanding factors that inhibit or promote the utilization of telecare in chronic lung disease

OBJECTIVES

To perform a process evaluation of a randomized controlled trial (RCT) of home telecare for the management of acute exacerbations of chronic obstructive pulmonary disease (COPD), using the normalization process model (NPM) as an explanatory framework.

METHODS

Semi-structured interviews were carried out with patients (n = 9) and nurses (n = 11) participating in a RCT. A framework approach to data analysis was used.

RESULTS

The telecare service did not provide an interactional advantage for the nurses providing this service and did not fit with the nurses' views of the most appropriate or preferred use of their skills. The telecare service seemed unlikely to become normalized as part of routine healthcare delivery, because the nursing team lacked confidence that it was a safe way to provide healthcare in this context and it was not perceived as improving efficiency.

DISCUSSION

The NPM effectively mapped onto the study findings and explained those factors that inhibited the routine delivery of COPD services by telecare.

Future patients? Telehealthcare, roles and responsibilities

Increasing use of information and communication technologies is said to be transforming health care. Telehealthcare enables medical consultations to be conducted between patients and health professionals across different locations. Such technologies imply new relationships between patients and health professionals. This study aimed to understand how policy and practice in relation to telehealthcare suggests new conceptualisations of 'the patient'. In-depth semistructured interviews (n = 38) were conducted with key informants from across the UK, known to have involvement or interest in telehealthcare from a variety of perspectives: health professionals (n = 11), patient advocates (n = 7), telemedicine experts (n = 6), policy-makers (n = 4), administrators (n = 4), researchers (n = 3) and technologists (n = 3). Interviews were conducted either in person or over the telephone, and were audio-recorded. Data were analysed thematically with ongoing cross-validation of data interpretation between members of the research team. The results indicated divergent views about the role of the patient, although accounts of patients becoming 'educated self-managers', taking on a more active role in their healthcare, were predominant. Beliefs about the impact of telehealthcare on patients were focused on perceived 'priorities' such as access, location of services, confidentiality and choice; however, there remains little understanding of the trade-offs that patients are willing to make in the context of technologically mediated health care. The results also highlight ideas around how patients relate to technologies; the extent to which technologies might fragment care and medicine in new or unexpected ways, and participation and absence of patients in decision-making about policies and services. The results of this study have important implications for the ways in which relationships between health professionals and patients are managed in practice, and raise important questions for public participation in service development.

Process evaluation for complex interventions in primary care: understanding trials using the normalization process model

BACKGROUND

The Normalization Process Model is a conceptual tool intended to assist in understanding the factors that affect implementation processes in clinical trials and other evaluations of complex interventions. It focuses on the ways that the implementation of complex interventions is shaped by problems of workability and integration.

METHOD

In this paper the model is applied to two different complex trials: (i) the delivery of problem solving therapies for psychosocial distress, and (ii) the delivery of nurse-led clinics for heart failure treatment in primary care.

RESULTS

Application of the model shows how process evaluations need to focus on more than the immediate contexts in which trial outcomes are generated. Problems relating to intervention workability and integration also need to be understood. The model may be used effectively to explain the implementation process in trials of complex interventions.

CONCLUSION

The model invites evaluators to attend equally to considering how a complex intervention interacts with existing patterns of service organization, professional practice, and professional-patient interaction. The justification for this may be found in the abundance of reports of clinical effectiveness for interventions that have little hope of being implemented in real healthcare settings.

Teledermatology in the UK: lessons in service innovation

BACKGROUND

Teledermatology has the potential to revolutionize the delivery of dermatology services by facilitating access to specialist services at a distance. In the U.K. over the previous decade there have been numerous attempts at introducing and using teledermatology; however, the development of teledermatology as routine service provision remains limited.

OBJECTIVES

To identify factors that promote successful use of teledermatology as a part of routine service provision.

METHODS

A longitudinal qualitative study of teledermatology, drawing on data from in-depth semistructured interviews; observations of systems in practice; and public meetings. Data were analysed collectively by the research team using established qualitative analytical techniques to identify key thematic categories. The sample consisted of teledermatology services within the U.K. (n = 12) studied over 8 years (1997-2005). Individual participants (n = 68 interviews) were consultant dermatologists, researchers, teledermatology nurses, administrators, patient advocates, general practitioners and technologists.

RESULTS

The analysis compared services that did or did not become part of routine healthcare practice to identify features that supported the normalization of teledermatology. Requirements for using and integrating teledermatology into practice included: political support; perceived benefit and relative commitment that outweighs effort; pragmatic approaches to proving efficacy and safety; perception of risk as being 'manageable' on the basis of professional judgement; high levels of flexibility in practice (in terms of individuals, technology and organization); and reconceptualizing professional roles.

CONCLUSIONS

Successful implementation of teledermatology as a routine service requires greater understanding of and attention to the interplay between social and technical aspects of teledermatology, and how this is accommodated both by healthcare professionals and the organizations in which they work.

Lessons from the implementation of a home telecare service

We conducted a qualitative evaluation of the introduction of a telenursing service. The service used an analogue videophone linked with a physiological monitoring device, which allowed the transmission of data between the patient's home and the hospital. A researcher kept a detailed diary of day-to-day activity for the first year of the project. Computer software for qualitative data analysis was used to code the text and the analysis followed the principles of constant comparison. The diary entries documented how the commercially available equipment was adapted to suit the organization and content of the nurses' work. The nurses made a number of suggestions to improve the user-friendliness of the equipment. The technology, the existing home care service (the comparison arm of the study) and the randomized controlled trial itself all underwent continuous change. The traditional randomized control design of trial has limitations in this situation, and there is a need for more realistic trial designs.

Factors influencing the evaluation of telehealth interventions: preliminary results from a qualitative study of evaluation projects in the UK

We have carried out a qualitative study of factors that influence the evaluation of telehealth. The study concerned six telehealth projects that are being tracked over two years. In the first 12 months of the study we carried out semistructured interviews and made observations of the participants in the projects. Each case study involved 5-15 subjects, many of whom were interviewed several times. The results indicate that important issues affecting telehealth evaluation include developing and maintaining the technology, reorganization of clinical and administrative duties, professional dynamics, and the difficulty of integrating service provision and evaluation. The findings suggest that the evaluation of telehealth interventions is highly complex, and that this complexity is often underestimated in the design and conduct of evaluation studies.

Systematic review of cost effectiveness studies of telemedicine interventions

OBJECTIVES

To systematically review cost benefit studies of telemedicine.

DESIGN

Systematic review of English language, peer reviewed journal articles.

DATA SOURCES

Searches of Medline, Embase, ISI citation indexes, and database of Telemedicine Information Exchange. STUDIES SELECTED: 55 of 612 identified articles that presented actual cost benefit data.

MAIN OUTCOME MEASURES

Scientific quality of reports assessed by use of an established instrument for adjudicating on the quality of economic analyses.

RESULTS

557 articles without cost data categorised by topic. 55 articles with data initially categorised by cost variables employed in the study and conclusions. Only 24/55 (44%) studies met quality criteria justifying inclusion in a quality review. 20/24 (83%) restricted to simple cost comparisons. No study used cost utility analysis, the conventional means of establishing the "value for money" that a therapeutic intervention represents. Only 7/24 (29%) studies attempted to explore the level of utilisation that would be needed for telemedicine services to compare favourably with traditionally organised health care. None addressed this question in sufficient detail to adequately answer it. 15/24 (62.5%) of articles reviewed here provided no details of sensitivity analysis, a method all economic analyses should incorporate.

CONCLUSION

There is no good evidence that telemedicine is a cost effective means of delivering health care.

What do we know about socioeconomic status and congestive heart failure? A review of the literature

OBJECTIVE

To examine and assess the available literature concerning the effects of socioeconomic status (SES) and congestive heart failure (CHF).

STUDY DESIGN

We examined electronic databases, including: MEDLINE, EMBASE, Social Science Citation Index, Science citation index, the Cochrane Database, and Bandolier. We hand searched recent copies of appropriate journals and scrutinized lists of identified papers. The search terms we used included "heart failure," "cardiac failure," "ventricular dysfunction," "social class," "socioeconomic," "poverty," and "deprivation." Two reviewers independently examined and selected papers for inclusion. A standardized data collection form was used for data extraction.

OUTCOMES MEASURED

We measured (1) prevalence; (2) differences in care (eg, use of diagnostic tests); (3) morbidity (eg, health care use); and (4) mortality.

DATA SOURCES

We examined all English-language abstracts or papers concerning human research related to the subject of SES and CHF, including all clinical trials, reviews, discussion papers, and editorials.

RESULTS

Only 8 clinical studies were identified that specifically examined aspects of the relationship between socioeconomic status and CHF. Key themes included increased hospitalization rates with increasing social deprivation; lower income inversely associated with being placed on a waiting list for transplantation; and that those of lower socioeconomic status had a greater severity of illness on admission.

CONCLUSIONS

There is a paucity of generalizable high-quality research in this subject area. Crucial issues not addressed include the effects, if any, of socioeconomic status on the behaviors of health care providers. Further investigation, with a more holistic approach, is necessary to inform future intervention strategies aimed at reducing excess mortality from CHF.

Exercise training and heart failure: a systematic review of current evidence

Chronic heart failure (CHEF) is a growing public health problem. Current guidelines provide detailed information regarding pharmacotherapy but little guidance about the value of exercise/cardiac rehabilitation programmes for individuals with this condition. To investigate the effects of exercise training upon CHF patients, a systematic literature review was carried out of trials (from 1966 to December 2000) which used as their main outcome measures the effects of exercise training upon: (a) physical performance; or (b) quality of life; or (c) morbidity/mortality. Databases searched include: MedLine; Science Citation Index; Social Sciences Citation Index; BIDS, Bandolier; Cochrane Database of Systematic Reviews (CDSR); NHS National Research Register (NRR); and Current Research in Britain (CRIB). Relevant bibliographic references from identified articles were also reviewed. Thirty-one trials were identified, comprising randomised controlled trials (RCTs) (14/31), randomised crossover trials (8/31), non-RCTs (2/31), and pre-test/post-test (7/31). Sample sizes were: 25 participants or fewer (20/31); 26 to 50 participants (7/31); 51 to 150 participants (4/31). Participants were predominantly younger with a mean age in 23/31 studies of 65 years or less, and male. Patients with comorbidities were often excluded. Positive effects were reported on physical performance (27/31), quality of life (11/16), mortality (1/31), and readmission rates (1/31). No cost-effectiveness analyses were identfied. We conclude that short-term physical exercise training in selected subgroups of patients with CHF has physiological benefits and positive effects on quality of life. This review highlights the continuing problem of clinical trials that include participants who are not representative of the general population of CHF patients seen in primary care. Further investigation of the utility and applicability of exercise training is essential.

A review of telemedicine cost-effectiveness studies

As interest in telemedicine grows, many of its proponents and vendors increasingly suggest that it is now time to move to full-scale implementation of telemedicine services in a variety of contexts throughout the world, and question the need for further evidence of its utility and cost-effectiveness. We have reviewed the published literature relating to cost-effectiveness studies in telemedicine and have identified some important weaknesses. Ten recommendations regarding the design of economic evaluations of telemedicine are suggested.

The role of telecare in the management of exacerbations of chronic obstructive pulmonary disease in the home

We examined home care as an alternative to hospital admission in exacerbations of chronic obstructive pulmonary disease (COPD). We performed a pilot study to investigate the feasibility of using telecommunications technology to assist in the support of acutely ill patients with exacerbations of COPD at home. Realtime, interactive video, via an analogue video-phone, was used to allow patients in their own homes to obtain nursing support from a nurse located at a distant base station. Six individuals, four male and two female, had video-phones installed in their homes by members of the nursing intervention team. The age range was 52-72 years, mean 61.5. These patients used the system on 18 occasions. Experience in home telecare, via interactive video, has been limited to provision of ongoing support for relatively stable individuals with chronic illness. This pilot project represents the first attempt at providing home telecare in the UK to those experiencing an acute exacerbation of their chronic illness, who would otherwise have merited acute hospital admission.
