Key result
A multiparameter clinical model predicts 12-month AECOPD readmission with an AUC of 0.79.
Why the study?
Existing predictive models often lack specificity for identifying hospitalized COPD patients at risk of multiple exacerbation-related readmissions.
Population
1287 patients hospitalized for AECOPD at a tertiary hospital in China
Design
Single-center retrospective cohort study
Follow-up
12 months

May aid inpatient risk stratification in AECOPD; extends prior models but leaves open prospective validation.

Effect estimate: AUC 0.79 (95% CI 0.75-0.83)
A seven-variable clinical prediction model using routinely available inpatient data can effectively identify hospitalized COPD patients at high risk for exacerbation-related readmission within 12 months.
Zhang et al. (2025) conducted a cohort in Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) (n=1,287). Clinical and physiological risk factors (sex, smoking status, diabetes, coronary artery disease, hemoglobin, FEV1% predicted, length of hospital stay) vs. Patients without these risk factors was evaluated on AECOPD-related readmission within 12 months following the index hospitalization (AUC 0.79, 95% CI 0.75-0.83). A prediction model incorporating sex, smoking status, diabetes, coronary artery disease, hemoglobin, FEV1% predicted, and length of hospital stay predicted 12-month exacerbation-related readmission with an AUC of 0.79.
