Abstract
Asthma education programs result in clinical improvement. However, most studies involved programs of up to 1 year of follow-up, and their efficacy in improving quality of life (QoL) is still controversial. The aim of this study was to evaluate the effectiveness of a program of patient education in asthmatics over 2 years. Thirty-seven asthmatic patients were randomly allocated to group A (usual treatment) and 32 to group B (usual treatment plus patient education program). The effectiveness of the education program was evaluated by comparing morbidity outcomes at baseline and 12 and 24 months afterwards. At baseline, no intergroup difference emerged in age, sex, smoking, asthma severity, atopy, FEV1, symptom-free days, use of rescue salbutamol, and QoL. One year later, group B subjects had an improvement in the overall QoL (from 5.8 ± 0.8 to 6.1 ± 0.7, p< 0.005), and in “Activities” (from 5.3 ± 0.9 to 5.7 ± 0.8, p< 0.05) and “Environment” (from 6.4 ± 1.0 to 6.8 ± 0.4, p< 0.05) domains. Two years later the “Activities” domain score increased in group B (from 5.3 ± 0.9 to 5.7 ± 1.1, p< 0.05). QoL did not vary in group A. The education program was ineffective in all other parameters at both follow-up time-points. In group A, a significant increase in medication expenses and a significant decrease in rescue salbutamol use was found 1 and 2 years after baseline, respectively. In conclusion, this education program improved QoL for 1 year, but the improvement was not sustained in the 2nd year.
