Background: Poor adherence to inhalation therapy is common among COPD patients. The IMB model is supported by previous studies as useful in promoting adherence to health behaviours. Methods: This pilot randomized controlled trial randomized 35 COPD patients to receive either the IMB-based programme or usual care. The 4-week IMB programme consisted of a face-to-face and two telephone sessions to empower patients with skills and knowledge on using inhalation therapy and support their goal attainment for treatment compliance. Outcome evaluation including adherence to inhalation therapy, inhalation techniques, disease impact, and quality of life was conducted at baseline and at 6 weeks after randomization. Feasibility of the IMB programme was evaluated by a satisfaction survey and implementation experience. Results: Thirty patients completed the study, with an attrition rate of 14.3%. The intervention group (n = 15) had significant improvements in inhalation adherence, inhalation techniques, and quality of life than the control group over the evaluation period. Patient satisfaction survey results and observations on programme implemen- tation suggested the feasibility of the IMB programme. Conclusion: A IMB model is a feasible and potentially effective intervention for improving COPD patients' adherence to inhalation therapy.
