Chronic obstructive pulmonary disease(COPD) is an incompletely reversible and progressive pulmonary disease characterized by airflow restriction, which is the third leading cause of death worldwide, accounting for 6% of all deaths worldwide. Acute exacerbation (AE) of COPD can accelerate the decline of lung function, worsening pulmonary symptoms, and increase the risk of death in patients. Health education, inhaled technical guidance training, individual self-management, psychological counseling, home oxygen therapy, nutritional support, and other comprehensive interventions can help improve the lung function of COPD patients, alleviate clinical symptoms, improve the quality of life. While a number of COPD applications have been developed, few provide comprehensive assessment and guidance for these kinds of patients. Therefore, the investigators aim to establish a bundle care mode based on the mode of "hospital-home-community-patient", clarify the impact of the management on prognosis, and evaluate the effect of mobile medical-assisted bundle management mode. In this randomized controlled trial(RCT), AECOPD patients will be divided into interventional or control groups randomly. Patients in the interventional group will receive mobile medication and standard of care at the same time (bundle care mode). While patients in the control group will receive standard of care only (traditional management mode). This study will be conducted to compare the effects of traditional and bundle care modes, and to formulate the implementation path and specifications of bundle care for AECOPD patients after discharge in China.
