Why the study?
Evaluating readmission rates at different follow-up time points and identifying factors associated with COPD-related readmission are important for risk assessment, early recognition of high-risk patients, and targeted interventions.
Population
Patients with COPD across 54 observational studies
Comparison
Factors associated with COPD-related readmission
Design
Systematic review and meta-analysis of observational studies
Follow-up
Within 1 month, 3 months, 6 months, and 1 year
Key result
Among patients hospitalized for chronic obstructive pulmonary disease, the pooled readmission rate was 15.2% at 1 month and increased progressively to 42.1% at 1 year.

Reinforces post-discharge COPD attention in practice; extends observational evidence but leaves causal intervention effects open.
Systematic Review (n=31,161,712)
COPD-related hospital readmission is highly prevalent, reaching 42.1% at 1 year, and is driven by multiple identifiable clinical factors, highlighting the need for targeted post-discharge interventions.
Tian et al. (2026) conducted a systematic review in Chronic obstructive pulmonary disease (COPD) (n=31,161,712). Hospital discharge for COPD was evaluated on 1-year COPD-related readmission rate (95% CI 33.60-51.10). Among patients hospitalized for chronic obstructive pulmonary disease, the pooled readmission rate was 15.2% at 1 month and increased progressively to 42.1% at 1 year.
