We found uncertain evidence for home-based asthma educational interventions compared to usual care, education delivered outside the home or a less-intensive educational intervention. Home-based education may improve quality of life compared to control and reduce the odds of hospitalisation compared to less-intensive educational intervention. Although asthma education is recommended in guidelines, the considerable diversity in the studies makes the evidence difficult to interpret about whether home-based education is superior to none, or education delivered in another setting. This review contributes limited information on the fundamental optimum content and setting for educational interventions in children. Further studies should use standard outcomes from this review and design trials to determine what components of an education programme are most important.
