[Value of quality of life evaluation in prognosis of chronic obstructive pulmonary disease].
To evaluate the quality of life in patients with chronic obstructive pulmonary disease (COPD) by COPD Assessment Test (CAT) and Body Mass Index, Airflow Obstruction, Dyspnea, Exercise Capacity Index (BODE).



One hundred patients with stable COPD admitted in Putuo People's Hospital were recruited in the study. CAT and BODE index were measured for each patient.The deaths and frequency of exacerbations were recorded during 3-year follow-up period,and the correlation between CAT and BODE in evaluating COPD prognosis was analyzed.



There were 28, 30, 29 and 13 patients with CAT score of 1, 2, 3 and 4, respectively; while there were 31, 29, 28 and 12 cases with BODE scores of 1, 2, 3 and 4. CAT scores were well correlated with BODE evaluation in terms of overall score and scores of 4 items (r= -0.237, -0.772, 0.789, -0.767, 0.888, respectively, Ps<0.05). COPD exacerbation incidence and mortality increased with the increasing CAT levels. The rank sum test showed that there were no significant differences between CAT and BODE index in the frequency of acute exacerbation(P<0.05); and in the death toll, the difference was not significant(1 group Χ2=0.919, 2 group Χ2=0.001, 3 group Χ2=0.177,4 group Χ2=0.322, Ps>0.05).



CAT is relevant to BODE in evaluating incidence of exacerbation and mortality for patients with COPD and CAT is more easily to be applied.
