Abstract:

Abstract To understand the current situation of pulmonary rehabilitation benefits in stable older COPD patients and analyze its influencing factors so as to provide reference for clinical promotion of pulmonary rehabilitation benefits in patients. Methods Retrospective collection of clinical data was carried out in 173 stable COPD patients who completed lung rehabilitation courses in a tertiary hospital of Nantong City from August 2020 to April 2023. Based on the changes in 6-minute walk test and St. George’s Respiratory Questionnaire（SGRQ） scores before and after participating in lung rehabilitation courses，patients were divided into benefit group and non-benefit group. Logistic regression analysis was used to analyze the influencing factors of lung rehabilitation benefits for patients. Results Among 173 patients who completed lung rehabilitation courses，93（53.76%） achieved benefits. Logistic regression analysis showed that age（OR=0.921），baseline 6-minute walk test（OR=0.976），baseline SGRQ score （OR=1.221），self-efficacy（OR=1.381），and comorbid osteoporosis（OR=0.406） were the influencing factors for pulmonary rehabilitation benefits in stable older COPD patients（P<0.05）. Conclusion Stable COPD patients have a lower rate of pulmonary rehabilitation benefits，and patients with poorer the baseline 6-minute walk test results， higher baseline SGRQ score and good self-efficacy are more likely to experience pulmonary rehabilitation benefits. The older in age and combined with osteoporosis hold higher the risk of not benefiting from pulmonary rehabilitation. Clinical medical staff need to consider the factors that affect the benefits of pulmonary rehabilitation interventions for patients，improve the intervention plan to promote the recovery of the patients.
