Group education on asthma for children and caregivers: a randomized, controlled trial addressing effects on morbidity and quality of life.
OBJECTIVE
To establish the efficacy in terms of morbidity and quality of life of a group education program on asthma aimed at children and caregivers.


METHODS
An open, randomized, controlled trial was undertaken in 13 primary health care centers in Spain, Cuba, and Uruguay and involved 245 children with active asthma aged 9 to 13 years and their caregivers. The intervention consisted of 3 educational sessions lasting 45 to 60 minutes each and was performed with 3 intervention groups: children alone, caregivers alone, and both children and caregivers. The outcome measures were difference between intervention and control groups in the rate of asthma attacks and hospital admission, as well as the quality of life of children and caregivers in the 6 months following the intervention.


RESULTS
The rate of asthma attacks per patient-year decreased when the intervention was given only to children (mean difference, -1.61; 95% confidence interval [CI], -2.87 to -0.34) or to both children and caregivers (-1.60; 95% CI, -2.88 to -0.31). Hospital admissions per patient-year decreased in the intervention groups children alone (-0.28; 95% CI, -0.51 to -0.05) and both children and caregivers (-0.25; 95% CI, -0.49 to -0.02). Education provided to caregivers alone was not associated with any changes in morbidity. No differences were observed in terms of quality of life between controls and any of the intervention groups.


CONCLUSIONS
Group education on asthma reduces morbidity but does not improve quality of life. The benefits are apparent when education is aimed at children but no additional benefit is obtained if the intervention is also aimed at their caregivers. Finally, group education for adult caregivers alone is not effective.
