Patients with COPD often miss the best time for early treatment and their pulmonary function will fall gradually. When bacterial or virus infects lung, it will increase risk of pneumonia and empyema for patients with COPD. However, literature of epidemiologic studies do not explore that COPD influence on empyema. This research used survival analysis to explore the risk and incidence of empyema with different COPD patients’ characteristics by using a retrospective cohort study method. The data were from the National Health Insurance Research Database (NHIRD). We selected the patients who had been diagnosed COPD from 2003-2010. The overall incidence rate of Empyema was higher in the COPD group (15.76/〖10〗^4 person-years) than in the non-COPD group (4.10/〖10〗^4 person-years). The adjusted hazard rate (HR) of Empyema was 3.25. The incidence rate of Empyema is associated with different comorbidities. The highest incidence rate of Empyema was in the Cancer with COPD group. This research offered the objective and correct data to doctor for making decision. Doctors can understand risk and incidence rate of empyema in COPD patients by our result and they can give more correct medical treatment to COPD patients who have higher risk of empyema.
