The COPD acute exacerbation times and hospitalizations due to COPD acute exacerbations between two groups were compared. In in-group comparison, the total number of COPD acute exacerbations and hospitalizations due to COPD acute exacerbations in both groups at 1 year after treatment apparently decreased compared with those before treatment (Comparison of exacerbations for COPD between the two groups of patients before and after treatment. Assessment of COPD acute exacerbation risk: based on the number of acute exacerbations in the previous year, it is assessed as a high-risk group for exacerbations if there are 2 or more moderate/severe exacerbations in a year, or one or more hospitalizations for an exacerbation.In the comparison of the proportion of high-risk patients with COPD acute exacerbation, the within-group comparison showed that the proportion of high-risk patients after treatment in that the control group decreased to 65.5%, and that in the intervention group reduced to 28.6%. Using paired Chi-square test, the proportion of high-risk patients with acute exacerbation in the control group and intervention group was statistically significant before and after treatment. The comparison between groups showed that the proportion of high-risk patients with acute exacerbation in the intervention group after treatment was significantly lower than that in the control group (XAssessment of COPD acute exacerbation risk between the two groups of patientsData were expressed as percentage or median (interquartile range), with significance level at In the comparison of cumulative number of patients with COPD acute exacerbation, within-group comparison shows that the cumulative number of cases with acute exacerbation in that control group and intervention group were significantly lower after treatment (In the comparison of the proportion of hospitalized patients between the two groups of patients with COPD acute exacerbations, the intra-group comparison results showed that the proportion of hospitalized patients after treatment in the control group decreased to 62.1%, while the proportion of patients treated in the intervention group decreased to 28.6%. With the paired Chi-square test, the difference in the proportion of hospitalized patients between the control group and the intervention group was statistically significant before and after treatment. The comparison between groups showed that the proportion of hospitalized patients in the intervention group after treatment was significantly lower than that in the control group (XIn the comparison of the cumulative number of inpatients with COPD acute exacerbations between the two groups, the intra-group comparison results showed that the cumulative number of cases with acute exacerbation in the control group and intervention group were significantly decreased after treatment (
