Prediction of 12-month exacerbation-related readmission in hospitalized patients with COPD: a single-center study in China

We developed a clinically applicable prediction model to identify hospitalized COPD patients at risk of exacerbation-related readmission within 12 months. The model incorporates routinely available clinical and physiological variables and demonstrated good internal performance. It may support early risk stratification and inform individualized post-discharge management. However, due to the single-center retrospective design and absence of external validation, further studies are needed to confirm its generalizability and real-world clinical utility.
