Randomized studies show that the best results come from patient-focused educational programs based on self-management (written and individualized action plan, self-monitoring, and regular medical review). The simple provision of information about asthma does not improve health outcomes. Teenagers with asthma are the most fragile patients, because of the lack of specific management for them. Repeated sessions are recommended and educational programs, started in childhood, might make it possible to prevent or at least decrease the risks of non-adherence during adolescence. The absence of consensus on educational interventions impedes the legibility of their impact.
