This NIHR-funded review identified three general principles for designing effective telehealth programmes for people with long-term health conditions. First, the technologies need to help people living with disease to build effective relationships with doctors, nurses and others. Second, there needs to be a good fit between the technology and everyday routine of the patient. Thirdly, the technology should provide a clear visual record of health results, such as blood glucose readings. The authors used realist review approaches to develop and test theories around what makes some telehealth programmes more successful than others.
For complex programmes, those made up of many interconnected parts, careful design and evaluation are particularly important. This type of study helps commissioners understand better how telehealth might work, in what circumstances and for whom. These three principles will be useful for those planning and evaluating telehealth programmes.
Why was this study needed?
In the UK, long-term conditions such as heart disease, lung conditions and diabetes account for around 60% of all deaths. Telehealth is where people monitor their own health at home and communicate information remotely to health professionals. While evidence is mixed, telehealth has been shown to improve people’s health for some long-term conditions, such as heart failure. It can reduce the number of hospital and GP appointments, which is more convenient for individuals and potentially saves the NHS money. Existing research has focused more on individual technologies or conditions. There is little evidence based guidance for introducing telehealth programmes, understanding how and why they work or designing interventions to make them more acceptable to patients. The NIHR funded this review to identify the mechanisms associated with successful implementation of telehealth interventions in people with three long-term conditions; chronic obstructive pulmonary disease, heart failure and diabetes. These three were chosen as important tracer conditions which had existing telehealth interventions with potential for improved uptake.
What did this study do?
This was a “realist review” – a type of review used to inform evidence-based policy by providing a detailed and practical understanding of how complex interventions work in the real world. The authors used three previous reviews of telehealth in long-term conditions to identify theories and characteristics linked to success and grouped them into themes. Qualitative studies gathering people’s views on telehealth interventions in heart failure, lung disease and diabetes helped refine the themes. Three reviewers independently looked at all of the studies before gathering to discuss and reach consensus on the most important information and themes. Fifteen studies were included in the review, six of which were from the UK.
What did it find?
- Telehealth can help to build trusting relationships between patient and healthcare professionals. People may feel anxious about taking on greater responsibility for managing their condition. Telemonitoring, such as remotely uploading blood glucose readings for a nurse to monitor and guide treatment, can provide an intermediary step to help people get used to more autonomous forms of self-management.
- Peer support, when tailored to gender and age, can enhance the effectiveness of telehealth. Peer support was particularly valuable where people’s immediate personal network may not be able to support them in making changes to their illness management.
- The effectiveness of telehealth interventions was affected by how well the intervention fitted with people’s needs and their daily routine. Adapting interventions to suit people’s needs and environments helped reach those who might otherwise not have accessed traditional face-to-face care.
- Practical barriers, such as integrating telehealth with existing systems, accessing the internet and space required for telehealth equipment, should be addressed to maximise the chance of successful implementation.
- Recording data such as blood glucose helped increase people’s awareness and engagement with their condition and care. Visible reminders helped to continue to engage people as their condition improved.
What does current guidance say on this issue?
NICE guidance recommends that people with chronic obstructive pulmonary disease (2010), heart failure (2010), and type 1 diabetes (2004) or type 2 diabetes (2009) are all offered education to help them manage their own condition and treatments. NICE does not have specific guidance on telehealth interventions for these conditions.
What are the implications?
This “realist” review provides practical information to inform the evidence-based design and implementation of telehealth interventions. Even if interventions have been shown to be clinically effective in some contexts, they may be unsuccessful if the factors needed to implement them are poorly understood. Therefore the review’s findings should be used in conjunction with evidence about the clinical effectiveness of particular telehealth interventions to identify and adapt interventions to maximise their impact.
For commissioners wanting more detail on the evidence base for telehealth a useful synthesis of the evidence on telehealth interventions for lung disease, diabetes and heart failure was published in 2013 by the University of York. This places the existing trials in context for a clinical commissioning group and includes a summary of the implications of the Whole System Demonstrator trial, a large recent trial and economic evaluation of telehealth. The suggestion is that local adaptation may offer a better chance of success than a ‘big-bang’ approach and this is supported by the conclusions of this realist review which provides some principles to consider in these local adaptations.
