To analyze the relationship between chronic disease resource utilization, disease perception and respiratory muscle group exercise compliance in elderly patients with chronic obstructive pulmonary disease (COPD).

A total of 219 COPD patients who were treated in our hospital from January 2020 to April 2025 were included in the study. The general information questionnaire, the chronic disease resource utilization questionnaire (CIRS), the simple disease perception questionnaire (BIPQ), and the breathlessness beliefs questionnaire(BBQ) were used for the investigation.Pearson correlation analysis of the three correlation, using SPSS macro program Model-4 to analyze whether the intermediary role of chronic disease resource utilization is established, and carry out Bootstrap test.

Among the 219 patients, the dyspnea fear score (14.23±4.67), CIRS score (49.74±6.41) and BIPQ score (50.32±8.56) were scored. CIRS score was negatively correlated with BIPQ score (r=-0.337) and dyspnea fear score (r=-0.256), while BIPQ score was positively correlated with dyspnea fear score (r=0.257) (P<0.05). The results of the mediating effect show that the direct effect of disease perception on the fear of dyspnea is 0.105, and the mediating effect of chronic disease resource utilization between disease perception and the fear of dyspnea is 0.035, accounting for 25.00% of the total effect.

The fear level of dyspnea in elderly COPD patients is generally at a high level, and the utilization of chronic disease resources has a partial mediating effect on disease perception and dyspnea fear level.
