BACKGROUND: Pharmacists are uniquely placed in the healthcare system to address critical issues in asthma management in the community. Various programs have shown the benefits of a pharmacist-led asthma care program; however, no such programs have previously been evaluated in Australia.
OBJECTIVE: To measure the impact of a specialized asthma service provided through community pharmacies in terms of objective patient clinical, humanistic, and economic outcomes.
METHODS: A parallel controlled design, where 52 intervention patients and 50 control patients with asthma were recruited in 2 distinct locations, was used. In the intervention area, pharmacists were trained and delivered an asthma care model, with 3 follow-up visits over 6 months. This model was evaluated based on clinical, humanistic, and economic outcomes compared between and within groups.
RESULTS: There was a significant reduction in asthma severity in the intervention group, 2.6 ± 0.5 to 1.6 ± 0.7 (mean ± SD; p < 0.001) versus the control group, 2.3 ± 0.7 to 2.4 ± 0.5. In the intervention group, peak flow indices improved from 82.7% ± 8.2% at baseline to 87.4% ± 8.9% (p < 0.001) at the final visit, and there was a significant reduction in the defined daily dose of albuterol used by patients, from 374.8 ± 314.8 µg at baseline to 198.4 ± 196.9 µg at the final visit (p < 0.015). There was also a statistically significant improvement in perceived control of asthma and asthma-related knowledge scores in the intervention group compared with the control group between baseline and the final visit. Annual savings of $132.84(AU) in medication costs per patient and $100,801.20 for the whole group, based on overall severity reduction, were demonstrated.
CONCLUSIONS: Based on the results of this study, it appears that a specialized asthma care model offers community pharmacists an opportunity to contribute toward improving asthma management in the Australian community.
