Home-based cardiac rehabilitation for people with heart failure is safe and effective. It improved exercise capacity slightly compared to care without cardiac rehabilitation, and may also be more convenient than centre-based rehabilitation as more people completed treatment.
This updated review included 19 trials, with seven from the UK. The home-based rehabilitation mostly took the form of aerobic exercise, though some included resistance training and there was wide variation in the nature and length of the programmes and the support offered at home. People involved in the studies were classed as having mild to moderate heart failure.
Nevertheless, this review provides stronger evidence to support NICE's recommendation that cardiac rehabilitation should be made more available and accessible to people with heart failure. It gives another safe option to centre-based care, which may increase participation.
Why was this study needed?
Heart failure affects around 900,000 people in the UK. Despite the effectiveness of cardiac rehabilitation in reducing readmission and risk of death from heart disease, availability and attendance in the UK is poor. On average, only 43% of people eligible actually attend, though this varies from 13 to 88% around the country. Efforts to improve access by using alternative settings and through telehealth have shown some promise, but strong evidence of their effectiveness is lacking.
Cardiac rehabilitation programmes typically include exercise, education, behaviour change, counselling, support and strategies that are aimed at targeting traditional risk factors for cardiovascular disease.
This review assessed whether home-based cardiac rehabilitation programmes could be a suitable alternative to centre-based programmes.
What did this study do?
This systematic review and meta-analysis pooled the results of 19 randomised controlled trials. It compared studies of home-based cardiac rehabilitation, centre-based cardiac rehabilitation or usual medical care that measured deaths, exercise capacity, health-related quality of life, adherence rates and cost.
Overall there were 1,290 adults aged between 44 and 70. Most were male, with mild to moderate heart failure causing breathlessness on mild to moderate exercise.
The home-based interventions were largely based around aerobic exercise, with only a handful including education or psychological elements. They ranged from two to five sessions of 10 to 60 minutes per week for eight weeks to 12 months. Professional support was offered as part of most home based interventions (home visits, phone calls or tele-monitoring).The results should be viewed with some caution as most studies were small, on average 55 participants and the intensity, frequency and duration of the programs varied widely.
What did it find?
- There was a 16% higher rate of completion of the home-based cardiac rehabilitation than the centre-based cardiac rehabilitation (relative risk [RR] 1.16, 95% confidence interval [CI] 1.02 to 1.32).
- Improvements in exercise capacity (cardiorespiratory fitness) measured by peak oxygen consumption were slightly more with home-based cardiac rehabilitation compared with usual care (VO2max mean difference 1.6ml/kg/min, 95% CI 0.8 to 2.4). There was no difference in the exercise capacity between home-based and centre-based rehabilitation.
- There was no difference in quality of life, hospitalisation or death with home-based cardiac rehabilitation compared with usual care.
- One UK trial reported on costs and found that both home-based and centre-based cardiac rehabilitation were cost effective compared to routine care due to the decrease in hospital admissions for heart failure.
What does current guidance say on this issue?
NICE 2010 guidelines recommend that a “supervised group exercise-based rehabilitation programme” should be offered to heart failure patients, but does not specify where this should take place. This is providing that the patient is stable and does not have a condition or device that would preclude an exercise-based rehabilitation programme.
They advise that the programme should include a psychological and educational component.
Cardiac rehabilitation is also recommended in NICE 2013 guidelines for people following a heart attack. In order to increase uptake, they recommend a variety of settings including the person’s home.
What are the implications?
This study supports home based cardiac rehabilitation for people with heart failure. It improved exercise capacity compared to usual care and was as effective as centre-based rehabilitation with a better adherence rate.
The wide range of programs included in the study makes it difficult to draw firm conclusions about what constitutes the best form of home-based rehabilitation, what components are required and what level of support (home visits or phone calls) is required.
