Objective To investigate the effect of health management on patients with chronic obstructive pulmonary disease(COPD)in stable phase.Methods 80 patients with COPD in our hospital were randomly divided into observation group and control group(n=40).The observation group received one year’s health management interventions,while the control group did not receive.They still maintained the original way of life.The change of smoking rates,pulmonary function index,blood gas analysis index and the quality of life(CAT score)of the two groups were observed after one year,and the situation of visiting Doctors of patients with acute exacerbation of the two groups were observed during one year period.Results In the observation group,the smoking rates decreased from 57.50%to 17.50%,the index of pulmonary function and blood gas analysis were significantly improved,the CAT score decreased from 29.75±4.24to26.13±4.42,and the quality of life improved,which all had a statistically significant differences(P<0.0001).In the control group,the smoking rates just decreased from 57.50%to 55%,which didn’t prove a statistical significance(P=0.317),the pulmonary function and the blood gas analysis further deteriorated,the quality of life further decreased,and the CAT score increased from 29.73±3.49 to 30.63±3.31,which all had a statistically significant differences(P<0.0001).During one year period,there were 11 patients with acute exacerbation in the observation group,and 23patientsin the control group.Hospitalizing rate was 27.5percent in the observation group,and 57.5percent in the control group.There were statistically significant differences between the control group and the observation group(P<0.05).Conclusion Standardized health management on patients with COPD in stable phase can effectively reduce smoking rates,improve the pulmonary function and body oxygen supply,reduce acute exacerbation repeatedly,delay the progression of disease,improve the quality of life of patients.It has great health benefits,economic benefits and social benefits,so that we should attach great importance to the health management interventions for the patients with COPD in stable phase,and promote and popularize it vigorously
