Evaluation of a novel educational strategy, including inhaler-based reminder labels, to improve asthma inhaler technique

Abstract

Objective To evaluate the feasibility, acceptability and effectiveness of a brief intervention about inhaler technique, delivered by community pharmacists to asthma patients. Methods Thirty-one pharmacists received brief workshop education (Active: n = 16, Control: n = 15). Active Group pharmacists were trained to assess and teach dry powder inhaler technique, using patient-centered educational tools including novel Inhaler Technique Labels. Interventions were delivered to patients at four visits over 6 months. Results At baseline, patients (Active: 53, Control: 44) demonstrated poor inhaler technique (mean ± S.D. score out of 9, 5.7 ± 1.6). At 6 months, improvement in inhaler technique score was significantly greater in Active cf. Control patients (2.8 ± 1.6 cf. 0.9 ± 1.4, p < 0.001), and asthma severity was significantly improved ( p = 0.015). Qualitative responses from patients and pharmacists indicated a high level of satisfaction with the intervention and educational tools, both for their effectiveness and for their impact on the patient–pharmacist relationship. Conclusion A simple feasible intervention in community pharmacies, incorporating daily reminders via Inhaler Technique Labels on inhalers, can lead to improvement in inhaler technique and asthma outcomes. Practice implications Brief training modules and simple educational tools, such as Inhaler Technique Labels, can provide a low-cost and sustainable way of changing patient behavior in asthma, using community pharmacists as educators.
