Chang et al identified predictors for readmission for an acute exacerbation of COPD (AECOPD). These can help to identify a patient who may benefit from more aggressive management. The authors are from Peking University Third Hospital in Beijing.


Patient selection: Chinese adult admitted for AECOPD


Parameters from the multivariate analysis:

(1) GOLD (Global Initiative for Chronic Obstructive Lung Disease) category

(2) serum C-reactive protein (CRP) at discharge in mg/L


GOLD Category

serum CRP in mg/L

1-Year Readmission


>= 3


A, B or C

>= 3



< 3


A, B or C

< 3



Additional risk factors from the univariate analysis:

(1) advanced age (mean 68 years for readmission, range 62 to 75, use >= 68 in implementation)

(2) >= 2 AECOPD in the past year

(3) FEV1 less than 50% of predicted

(4) COPD Assessment Test (CAT) score >= 10
