Objective To explore the application effect of studio-based extended care led by specialist nurses in stable COPD patients in county medical community. Methods According to the odd and even numbers, 179 discharged COPD patients were divided into a control group (n=90) and an intervention group (n=89). The control group was given routine extended care, while the intervention group relied on the county medical community and carried out extended care dominated by studio specialist nurses. Results After 2 years of intervention, the ratio of measured values to predicted values of the forced expiratory volume in one second (FEV1), the ratio of FEV1 to forced vital capacity, and the score of COPD Assessment Test in the intervention group were significantly better than those in the control group, its average times of acute aggravation in the 2 years was significantly less than that in the control group, and its success rate of quitting smoking was significantly higher than that in the control group (all P<0.05). Conclusion Studio-based extended care led by specialist nurses in the county medical community, is conducive to increasing the success rate of quitting smoking in stable COPD patients, improving their pulmonary function and delaying their disease progression.
