Abstract:

Objective: To explore the effect of staged intervention based on the transtheoretical model (TTM) on rehabilitation exercise compliance in patients with chronic obstructive pulmonary disease (COPD) complicated with frailty. Methods: A total of 116 patients with COPD complicated with frailty admitted to Qingpu Branch of Zhongshan Hospital Affiliated to Fudan University from January 2023 to August 2023 were enrolled as research subjects. They were divided into the control group and the observation group by the random number table method. One patient in the observation group dropped out due to sudden pneumothorax during hospitalization. Ultimately, 58 cases were included in the control group and 57 cases in the observation group. The control group received routine exercise health education, while the observation group received staged intervention based on the TTM on the basis of routine nursing. After 6 months of intervention, a self-designed rehabilitation exercise compliance scale was adopted to evaluate patients’ compliance, and the differences in compliance between the two groups were compared. Results: After intervention, the full compliance rate of rehabilitation exercise in the observation group was significantly higher than that in the control group (63.16% (36/57) vs. 27.59% (16/58)), while the non-compliance rate was markedly lower (7.02% (4/57) vs. 48.28% (28/58)), with statistically significant differences (χ²=31.256, P<0.001). After intervention, the proportion of patients in the pre-contemplation stage in the observation group (15.80%, 9/57) was obviously lower than that in the control group (60.34%, 35/58); the proportions of patients in the action stage and maintenance stage in the observation group were 52.63% (30/57) and 28.07% (16/57) respectively, which were significantly higher than those in the control group (31.04% (18/58) and 3.45% (2/58)). The differences were statistically significant (Z=-5.405, P<0.001). Conclusion: Staged intervention based on the TTM can significantly improve rehabilitation exercise compliance in patients with COPD complicated by frailty.
