Current in-hospital management of exacerbations of COPD is suboptimal, and patient outcomes are poor. The primary aim of this study was to evaluate whether implementation of a care pathway (CP) for COPD improves the 6 months readmission rate. Secondary outcomes were the 30 days readmission rate, mortality, length of stay and adherence to guidelines. An international cluster randomized controlled trial was performed in Belgium, Italy and Portugal. General hospitals were randomly assigned to an intervention group where a CP was implemented or a control group where usual care was provided. The targeted population included patients with COPD exacerbation. Twenty-two hospitals were included, whereof 11 hospitals (n=174 patients) were randomized to the intervention group and 11 hospitals (n=168 patients) to the control group. The CP had no impact on the 6 months readmission rate. However, the 30 days readmission rate was significantly lower in the intervention group (9.7%; 15/155) compared to the control group (15.3%; 22/144) (odds ratio =0.427; 95% confidence interval 0.222-0.822; P=0.040). Performance on process indicators was significantly higher in the intervention group for 2 of 24 main indicators (8.3%). The implementation of this in-hospital CP for COPD exacerbation has no impact on the 6 months readmission rate, but it significantly reduces the 30 days readmission rate.
