Patient profiles associated with AECOPD rehospitalisation. Data are represented as sunburst plots. The analysis was performed to segregate the 25,090 patients with at least one rehospitalisation for AECOPD (green segments) and the remaining 108,538 patients who were not rehospitalised for AECOPD (purple segments). The grey segments correspond to segments where the purity score is too low to categorize patients with certainty (either rehospitalised or not). Left: decision tree analysis including AECOPD previous hospitalisation as a source variable; right: decision tree analysis excluding AECOPD previous hospitalisation.

Abbreviation: AECOPD, acute exacerbations of chronic obstructive pulmonary disease
