Vai trò của dược sĩ lâm sàng trong cải thiện kỹ thuật sử dụng các thuốc dạng hít ở bệnh nhân COPD

Abstract

Objective: To evaluate the benefit of pharmacist-led intervention on the improvement of inhaler technique for patients with COPD at Hai Duong Lung Hospital. Subject and method: COPD patients were treated as outpatients and managed in “Project on the Prevention of Chronic Obstructive Pulmonary Disease” between 11/2018 and 02/2019 at Hai Duong Lung Hospital. This study is a prospective descriptive cohort study having intervention. Result: After 3 months of intervention, the percentage of patients with incorrect inhaler technique at each step decreased significantly. Regarding the sum of important steps, there was a downward trend in the rate of patients committing error (s) with p<0.001 (MDI), p<0.05 (DPI). The proportion of patients who achieved “Optimal technique” increased from 28.6% and 31.1% (T₀) to 73.8% and 75.0% (T₃) for MDI and DPI, respectively. COPD patients with 1-year-older reduce the ability to use inhaler devices correctly by 12% (OR = 0.88, 95% CI: 0.85 - 0.92, p<0.001). Patients joining frequently in COPD club had the correct technique over 2 times as much as those who did not (OR = 2.03, 95% CI: 1.5 - 2.74, p<0.001). A high education level was the third explanatory factor for correct inhaler technique (OR = 3.99, 95%CI: [1.86 - 8.52], p<0.001). Conclusion: Clinical pharmacist plays a vital role in improving inhaler technique of COPD patients at Hai Duong Lung Hospital. There were three factors affecting the mistake (s) in inhalation technique of COPD patients are age, education, and frequency of joining the COPD club.
