Skills in handling Turbuhaler, Diskus in the west of China

OBJECTIVE: The purpose of this study was to evaluate the inhaler skills of patients with asthma and chronic obstructive pulmonary disease in a hospital in western China after receiving one medication education by pharmacists and the factors related to these skills. METHODS: We included 96 subjects using Turbuhaler and 74 subjects using Diskus in a hospital in western China. They were educated once by pharmacists before medication, and then their skills of operating these inhalers were visually evaluated the next time they were used. Using the seven-step inhalation administration method designed by AnnaMurphy, a clinical pharmacist at GLENFIELD Hospital in the UK, the inhaler use technique score scale was established and scored in turn. The age, sex, time of first illness, smoking status, education level and type of health insurance purchased by each patient were recorded to assess their relationship with overall inhaler skills. RESULTS: 19.8% of the subjects who used Turbuhaler could not use it correctly, and 43.2% of the subjects who used Diskus could not use it correctly. The step with the highest error rate with Turbuhaler and Diskus is to "exhale slowly to residual volume". Chi-square test was carried out for each step of the operation of the two kinds of inhalers, and it was found that there was a significant difference in the operation accuracy of the two kinds of inhalers in the first, third and eighth steps. In univariate analysis, advanced age, female and low educational level were related to the lack of inhaler technology, but in multivariate analysis, only low educational level was a significant independent risk factor. CONCLUSION: Among the patients with asthma and chronic obstructive pulmonary disease in western China, some patients have good inhaler operation skills, but there are still many patients who can not use inhalers correctly, and the lower education level is significantly related to the incorrect use of inhalers.
