Descripción: Objective. To evaluate the clinical effectiveness of a community pharmacy based education program for asthma patients.
Design. A randomized controlled trial was conducted in 16 community pharmacies. Interventions: Patients in the intervention group (n=53) received three sessions of individualized asthma education from pharmacists. In addition, pharmacists also prepared a written action plan in consultation with patients' physicians. Patients in the control group (n=53) did not receive any asthma education during the study.
Outcome Measures. Asthma symptoms (the primary outcome), asthma knowledge, medication compliance, deep expiratory pressure percentage (DEP%), inhaler technique, quality of life (QOL), and heath resources utilization were measured.
Results. The mean score of asthma symptoms, the primary outcome, decreased more in the intervention group than in the control group (between group difference = -0.299, 95% CI, -0.71; 0.11), though this between group difference was not statistically significant (P=0.148). As to the secondary outcomes, patients in the intervention group had significant improvements in "overall mean score of QOL" (between group difference = 0.43, 95% CI, 0.023; 0.83), "symptom domain of QOL" (between group difference = 0.50, 95% CI, 0.04; 0.96), and "inhaler technique of Aerosol-dosing only" (between group difference = 1.77, 95% CI, 0.36; 3.18). Except for QOL and inhaler technique, the other four secondary outcomes did not achieve any significant differences between the two study groups.
Conclusions. Most of the study results were not statistically significant. One important reason for this was the lack of power due to the poor success in patient recruitment. The study also highlighted some of the limitations and difficulties in implementing a community pharmacy based asthma education program. Despite these difficulties, some benefits were found. Therefore, we suggest that future studies should focus on overcoming the limitations and difficulties observed in this study.
