COPD, DISEASE
This study is mainly divided into two groups, experimental group and control group. Both the experimental and control groups received standard medical care provided in the hospital. The control group was given routine intervention and health education guidance, including basic knowledge of the disease, smoking cessation, self-management skills, an action plan for COPD acute exacerbations, exercise training guidance (respiratory training), social psychological guidance and nutritional support. After discharge, telephone follow-up was conducted once a week for 15–20 min for 12 weeks. The main contents of follow-up included asking patients about their current health status, informing patients to seek medical treatment in time if their condition worsened, and answering patients' common health questions. In the experimental group, a PA program based on BCW theory was implemented on the basis of routine nursing, as follows. A flowchart of the intervention for the protocol is provided in Fig. Flowchart of the intervention for the protocol.
