Telemedicine versus face to face patient care: effects on professional practice and health care outcomes

Telecare motivational interviewing for diabetes patient education and support: a randomised controlled trial based in primary care comparing nurse and peer supporter delivery

BACKGROUND

There is increasing interest in developing peer-led and 'expert patient'-type interventions, particularly to meet the support and informational needs of those with long term conditions, leading to improved clinical outcomes, and pressure relief on mainstream health services. There is also increasing interest in telephone support, due to its greater accessibility and potential availability than face to face provided support. The evidence base for peer telephone interventions is relatively weak, although such services are widely available as support lines provided by user groups and other charitable services.

METHODS/DESIGN

In a 3-arm RCT, participants are allocated to either an intervention group with Telecare service provided by a Diabetes Specialist Nurse (DSN), an intervention group with service provided by a peer supporter (also living with diabetes), or a control group receiving routine care only. All supporters underwent a 2-day training in motivational interviewing, empowerment and active listening skills to provide telephone support over a period of up to 6 months to adults with poorly controlled type 2 diabetes who had been recommended a change in diabetes management (i.e. medication and/or lifestyle changes) by their general practitioner (GP). The primary outcome is self-efficacy; secondary outcomes include HbA1c, total and HDL cholesterol, blood pressure, body mass index, and adherence to treatment. 375 participants (125 in each arm) were sought from GP practices across West Midlands, to detect a difference in self-efficacy scores with an effect size of 0.35, 80% power, and 5% significance level. Adults living with type 2 diabetes, with an HbA1c > 8% and not taking insulin were initially eligible. A protocol change 10 months into the recruitment resulted in a change of eligibility by reducing HbA1c to > 7.4%. Several qualitative studies are being conducted alongside the main RCT to describe patient, telecare supporter and practice nurse experience of the trial. DISCUSSION AND IMPLICATIONS OF THE RESEARCH: With its focus on self-management and telephone peer support, the intervention being trialled has the potential to support improved self-efficacy and patient experience, improved clinical outcomes and a reduction in diabetes-related complications.

Telehealth videoconferencing: improving home parenteral nutrition patient care to rural areas of Ontario, Canada

BACKGROUND

Telehealth videoconferencing is a medium for health care professionals to communicate and care for patients living in remote areas. The aim of this study was to provide a survey to examine management outcome of home parenteral nutrition (HPN) patients when followed by telehealth as an alternative modality of care.

METHODS

Twenty-six individuals who were identified to benefit from tele-health were invited to participate in a satisfaction survey. The survey was sent to patients by postal mail. The survey also documented the incidence of line sepsis and other medical HPN complications. A cost analysis was also performed according to technology, human resources, and infrastructure.

RESULTS

Eighty-one telehealth videoconference sessions have been held since the inception of telehealth in 2002. Of the current telehealth patients, 13 were eligible for the survey. The satisfaction survey response rate was 11/13 (84.6%). The average line sepsis rate for the 13 patients was 0.89/1000 catheter-days. All patients were generally satisfied with videoconferencing as an alternative method of communication and care for new consultation, patient and family education, and follow-up. Travel time and costs to the patients, their families, and the health care system were significantly less. For example, a patient who resides 611 km from Toronto would cost CDN (Canadian) 724.00 dollars for flight and accommodation to meet with the team at the HPN clinic in Toronto.

CONCLUSION

Telehealth incorporated the cost-saving ability for HPN patients to maintain proper medical care, support, and collaboration of specialists inaccessible to their local community. Thus, its strongly positive role in HPN care deserves further consideration for a national application.

Implementation of the concept of home hospitalisation for heart patients by means of telehomecare technology: integration of clinical tasks

Purpose

To explore how the implementation of the concept ‘Home hospitalisation of heart patients’ by means of telehomecare technology influences the integration of clinical tasks across healthcare sectors.

Theory

Inter-organisational theory.

Methods

The case study approach was applied. Triangulations of data collection techniques were used: documentary materials, participant observation, qualitative and focus group interviews.

Results

The clinical decision-making and task solving became multidisciplinary and integrated with the implementation of telehomecare and, therefore, complex in terms of the prescription and adjustment of patient medicine. Workflows between healthcare professionals across sectors changed from sequential to collective client flows. Pre-existing procedures for patient care, treatment, and responsibility were challenged. In addition, the number of tasks for the district nurses increased. Integration in the clinical task-solving area increases fragmentation in the knowledge technologies in a network perspective.

Conclusions

Implementing the concept of ‘Home hospitalisation of heart patients’ by means of telehomecare technology will result in a more integrated clinical task-solving process that involves healthcare professionals from various sectors. Overall, the integration of clinical tasks between hospital and district nursing will result in a direct benefit for the heart patients.

A psychological approach to providing self-management education for people with type 2 diabetes: the Diabetes Manual

BACKGROUND

The objectives of this study were twofold (i) to develop the Diabetes Manual, a self-management educational intervention aimed at improving biomedical and psychosocial outcomes (ii) to produce early phase evidence relating to validity and clinical feasibility to inform future research and systematic reviews.

METHODS

Using the UK Medical Research Council's complex intervention framework, the Diabetes Manual and associated self management interventions were developed through pre-clinical, and phase I evaluation phases guided by adult-learning and self-efficacy theories, clinical feasibility and health policy protocols. A qualitative needs assessment and an RCT contributed data to the pre-clinical phase. Phase I incorporated intervention development informed by the pre-clinical phase and a feasibility survey.

RESULTS

The pre-clinical and phase I studies resulted in the production in the Diabetes Manual programme for trial evaluation as delivered within routine primary care consultations.

CONCLUSION

This complex intervention shows early feasibility and face validity for both diabetes health professionals and people with diabetes. Randomised trial will determine effectiveness against clinical and psychological outcomes. Further study of some component parts, delivered in alternative combinations, is recommended.

Implementing telehealth to support medical practice in rural/remote regions: what are the conditions for success?

Background

Telehealth, as other information and communication technologies (ICTs) introduced to support the delivery of health care services, is considered as a means to answer many of the imperatives currently challenging health care systems. In Canada, many telehealth projects are taking place, mostly targeting rural, remote or isolated populations. So far, various telehealth applications have been implemented and have shown promising outcomes. However, telehealth utilisation remains limited in many settings, despite increased availability of technology and telecommunication infrastructure.

Methods

A qualitative field study was conducted in four remote regions of Quebec (Canada) to explore perceptions of physicians and managers regarding the impact of telehealth on clinical practice and the organisation of health care services, as well as the conditions for improving telehealth implementation. A total of 54 respondents were interviewed either individually or in small groups. Content analysis of interviews was performed and identified several effects of telehealth on remote medical practice as well as key conditions to ensure the success of telehealth implementation.

Results

According to physicians and managers, telehealth benefits include better access to specialised services in remote regions, improved continuity of care, and increased availability of information. Telehealth also improves physicians' practice by facilitating continuing medical education, contacts with peers, and access to a second opinion. At the hospital and health region levels, telehealth has the potential to support the development of regional reference centres, favour retention of local expertise, and save costs. Conditions for successful implementation of telehealth networks include the participation of clinicians in decision-making, the availability of dedicated human and material resources, and a planned diffusion strategy. Interviews with physicians and managers also highlighted the importance of considering telehealth within the broader organisation of health care services in remote and rural regions.

Conclusion

This study identified core elements that should be considered when implementing telehealth applications with the purpose of supporting medical practice in rural and remote regions. Decision-makers need to be aware of the specific conditions that could influence telehealth integration into clinical practices and health care organisations. Thus, strategies addressing the identified conditions for telehealth success would facilitate the optimal implementation of this technology.

Staff Perceptions of Job Satisfaction and Life Situation before and 6 and 12 Months after Increased Information Technology Support in Dementia Care

We measured staff members’ satisfaction with their work before and after increased information technology (IT) support in dementia care. Comparisons were also performed of perceived life satisfaction and sense of coherence. Data were collected before, and 6 and 12 months after implementation of the first part of an IT support project. Instruments used were the Satisfaction with Work Questionnaires, the Life Satisfaction Questionnaire (LSQ) and the Sense of Coherence (SOC) scale. The study was performed in a residential home for persons with dementia. The participants were 33 staff members. The IT technology included general and individualized passage alarms, sensor-activated night-time illumination, fall detectors and Internet communication. Results showed that staff members’ job satisfaction and perceived quality of care improved in comparison with the control group. Personal development, workload, expectations and demands, internal motivation and documentation, as well as the total scores for ‘psychosocial aspects of job satisfaction’ and ‘quality of care aspects’, increased in the experimental group. There were significant interaction effects for the factors family relation, close friend relation (LSQ), the total SOC scale and the meaningfulness subscale. The study showed that IT support in dementia care increased staff members’ satisfaction with their work in several ways.

[Proliferation of paradigmatic ruptures: the case of evidence-based medicine]

The present study describes the phenomenon of paradigmatic ruptures proliferation in the biomedical literature. The current distortion is discussed, which has conferred in the last decades an opposite meaning to the term originally proposed by Thomas Khun. In most part, it is realized that pseudo-ruptures refer to technical details associated to specific contexts. It is pointed out the case of evidence- based medicine (EBM), proclaimed as one of these paradigmatic ruptures, but which essentially corroborates old concepts. Some conceptual errors are stressed as well as attempts to apply EBM assumptions to phenomena associated to subjectivity and social dynamics and other particular study subjects of social sciences. Twelve inconclusive meta-analyses are described to exemplify the paradoxes emerging from this approach. The criticism to some EBM features is summarized through the effects of epistemological bafflement, producing conceptual inaccuracies of the term; the defensive effect to which other disciplines are induced for not being adequate to such rationality; and the tendency of universal understanding of phenomena through the perspective of randomized double-blind studies.

Evaluation of health information systems-problems and challenges

OBJECTIVES

Information technology (IT) is emerging in health care. A rigorous evaluation of this technology is recommended and of high importance for decision makers and users. However, many authors report problems during the evaluation of information technology in health care. In this paper, we discuss some of these problems, and propose possible solutions for these problems.

METHODS

Based on own experience and backed up by a literature review, some important problems during IT evaluation in health care together with their reasons, consequences and possible solutions are presented and structured.

RESULTS AND CONCLUSIONS

We define three main problem areas-the complexity of the evaluation object, the complexity of an evaluation project, and the motivation for evaluation. Many evaluation problems can be subsumed under those three problem areas. A broadly accepted framework for evaluation of IT in healthcare seems desirable to address those problems. Such a framework should help to formulate relevant questions, to find adequate methods and tools, and to apply them in a sensible way.

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.

Clinical outcomes resulting from telemedicine interventions: a systematic review

BACKGROUND

The use of telemedicine is growing, but its efficacy for achieving comparable or improved clinical outcomes has not been established in many medical specialties. The objective of this systematic review was to evaluate the efficacy of telemedicine interventions for health outcomes in two classes of application: home-based and office/hospital-based.

METHODS

Data sources for the study included deports of studies from the MEDLINE, EMBASE, CINAHL, and HealthSTAR databases; searching of bibliographies of review and other articles; and consultation of printed resources as well as investigators in the field. We included studies that were relevant to at least one of the two classes of telemedicine and addressed the assessment of efficacy for clinical outcomes with data of reported results. We excluded studies where the service did not historically require face-to-face encounters (e.g., radiology or pathology diagnosis). All included articles were abstracted and graded for quality and direction of the evidence.

RESULTS

A total of 25 articles met inclusion criteria and were assessed. The strongest evidence for the efficacy of telemedicine in clinical outcomes comes from home-based telemedicine in the areas of chronic disease management, hypertension, and AIDS. The value of home glucose monitoring in diabetes mellitus is conflicting. There is also reasonable evidence that telemedicine is comparable to face-to-face care in emergency medicine and is beneficial in surgical and neonatal intensive care units as well as patient transfer in neurosurgery.

CONCLUSIONS

Despite the widespread use of telemedicine in virtually all major areas of health care, evidence concerning the benefits of its use exists in only a small number of them. Further randomized controlled trials must be done to determine where its use is most effective.
