A randomized, controlled trial of an interactive educational computer package for children with asthma.

Abstract

The purpose of this study was to evaluate the impact and acceptability of an educational multimedia program designed to promote self-management skills in children with asthma. We conducted a randomized, controlled trial with measures at baseline and 1- and 6-month follow-up. The trial was conducted in pediatric outpatient respiratory clinics in 3 United Kingdom hospitals. Participants included 101 children aged 7 to 14 years under the care of hospital-based asthma services. The children were randomly assigned to receive an asthma information booklet alone or the booklet plus The Asthma Files, an interactive CD-ROM for children with asthma. Asthma knowledge was the primary outcome measure. Other measures included asthma locus of control, lung function, use of oral steroids, and school absence. At the 1-month follow-up (n = 99), children in the computer group had improved knowledge compared with the control group and a more internal locus of control. There were no differences in objective lung-function measures, hospitalizations, or oral steroid use. The study participants were positive in their evaluation of the intervention. At the 6-month follow-up (n = 90), significantly fewer children in the intervention group had required oral steroids and had had time off school for asthma in the previous 6 months. The difference did not reach statistical significance in the intention-to-treat analysis for both steroid use and school absence. The Asthma Files was found to be an effective and popular health education tool for promoting asthma self-management skills within pediatric care.
