ObjectiveTo assess the effect of an educational intervention on asthma control and quality of life.DesignA randomised clinical trial of patients with asthma, with an intervention group (IG) and a control (GC). Asthma control and quality of life was measured in both groups at baseline and every three months for one a year. Blinding was only possible in the collection and analysis of data.LocationTwo urban Primary Care Health CentresParticipantsA total of 163 patients aged 18 to 55 years were included: 84 were assigned to the IG and 79 to the CG. The follow-up was completed by 104 patients (GI: 55 and GC 49).Intervention GiThree educational sessions in small interactive groups. The first session was at the beginning of spring, the second 15 days later, and the third 6 months later, to recall the knowledge.Main MeasurementsAsthma control level and quality of life using ACT(Asthma Control Test) and the AQLQ (Asthma Quality of life Questionnaire).ResultsIn the third month, statistically significant differences were detected in the percentage of patients with good control [(P=.0002), 75% in the GI, and 48.5% in the GC, Relative Risk (RR)=1.6 [1.2 to 2.1], Number Needed to Treat (NNT)=3.8 [2.4 to 9.4], and an improvement in levels of quality of life from baseline (P=.005), RR=2.3 [1.3 to 4.1], NNT: 4.3 [2.6 to 12.4]. No differences were detected in the remaining sessions.ConclusionsThese interventions are effective in improving the control and quality of life in short-term, which can guide us in choosing the best time to do it.Copyright © 2012 Elsevier España, S.L.
