Objective:To explore the clinical value of application of Teach-back education model in the process of health education for patients with chronic obstructive pulmonary disease (COPD) .Methods:Using the convenient sampling method, a total of 100 COPD patients admitted to Huzhou Central Hospital from March 2018 to March 2019 were selected as the research objects. They were randomly divided into the control group and the study group, with 50 cases in each group. The control group adopted conventional health education, while the intervention group adopted Teach-back education model on the basis of conventional health education. COPD Assessment Test (CAT) scores, blood gas indexes, lung function indexes of patients of the two groups before and after the intervention, as well as the recurrence and readmission status were compared and analyzed 3 months after discharge.Results:After intervention, CAT score of the study group was lower than that of the control group, blood gas analysis indexes such as partial pressure of carbon dioxide (PaCO 2) , partial pressure of oxygen (PaO 2) and blood oxygen saturation (SaO 2) were better than those of the control group, and forced expiratory volume in one second (FEV 1) and forced expiratory volume in one second/forced vital capacity (FEV 1/FVC) levels were higher than those of the control group, and the differences were statistically significant ( P<0.05) .Three months after discharge, the frequency of disease attacks in the study group was less than that in the control group and the readmission rate was lower than that in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The use of Teach-back education model in health education for COPD patients can significantly improve the patients' respiratory symptoms, improve lung function, PaO 2 and SaO 2, reduce the recurrence and readmission of patients and optimize quality of life of patients, which is worthy of clinical promotion and application.
