After reviewing the literature, extracting per tinent information, and evaluating the risk of bias for the included studies, statistical analysis was performed using Stata 15.1.Results: Thir teen papers(12 in English and 1 in Chinese), representing 2527 patients, met the search criteria and were included in the meta-analysis. The results showed that the combined effect size of COPD patients making at least one operational error was 76%(95% CI: 0.69–0.83). The error rate varied with inhaler type;the combined effect size error for powered inhalers was 66%(95% CI: 0.57, 0.74), 67%(95% CI. 0.57, 0.77) for metered-dose inhalers(MDI), and 51%(95% CI: 0.38, 0.64) for soft mist inhalers(SMI).Conclusions: More than 75% of patients with COPD were unable to consistently use inhalers correctly, with the highest error rate for MDI. Therefore, health care providers must continue to educate patients on proper use of inhaler, ensuring their correct use and reducing the risk of acute COPD exacerbations.展开更多
