Association of Charlson comorbidity index with 28- and 90-day mortality in patients with severe acute kidney injury requiring CRRT: A retrospective cohort study

Abstract

Severe acute kidney injury (AKI) requiring continuous renal replacement therapy (CRRT) carries high short‑term mortality. This study evaluated whether the Charlson Comorbidity Index (CCI) independently predicts 28‑ and 90‑day mortality and adds incremental prognostic value beyond established clinical variables.
