Construction and application of standardized management mode for inhalation therapy of COPD patients assisted by digital medical technology

INTERVENTION: control group: Provide inhalation medication guidance for patients with chronic obstructive pulmonary disease. At the initial visit of the patient, provide one‐on‐one guidance to the patient and caregiver, mainly introducing the ingredients, effects, common adverse reactions, contraindications, and precautions of the medication used; Explain the purpose of medication and demonstrate the use of inhalation devices: oral explanation+demonstration by the instructor+extraction of training points; Combining mirror learning to guide patients in simulating physical models and describing medication methods and key knowledge points. ;Test group:Implementation of a digital healthcare technology‐assisted standardized nursing management model for inhalation therapy in COPD patients, featuring digital management across three dimensions: capability, motivation, and trigger.; CONDITION: chronic obstructive pulmonary disease PRIMARY OUTCOME: Inhalation therapy compliance;Inhalation Technology Assessment Review; SECONDARY OUTCOME: Number of acute exacerbations of COPD (person times and total occurrence);Changes in cardiopulmonary function: changes in lung function and 6‐minute walking distance before and after intervention;Rating of Dyspnea Scale: Changes in Rating of Modified Medical Research Council Questionnaire (mMRC) before and after Intervention;Evaluation of Disease Control Status: Changes in Chronic Obstructive Pulmonary Disease Assessment Test (CAT) Scores Before and After Intervention;Pulmonary function indicators; INCLUSION CRITERIA: 1. Previously used at least one inhalation agent (such as salmeterol fluticasone powder inhalation, budesonide formoterol powder inhalation, tiotropium bromide powder inhalation, etc.); 2. Having a smartphone, able to access the internet and use apps on the phone; 3. The patient has communication skills and can independently or with the assistance of the researcher fill out the required research questionnaire; 4. I and my caregiver agree to cooperate with the relevant requirements of the research plan and sign an informed consent form.
