Renin-angiotensin aldosterone system inhibitors usage among hospitalized patients with acute kidney injury: a retrospective study

Under-recognition of AKI was predominant and might be the main reason for continuing RAASi after AKI onset. Continuation of RAASi during an AKI episode was associated with poor kidney recovery in the short term. Timely recognition of AKI should be improved, and a dynamic risk-benefit ratio evaluation for RAASi is required to achieve optimal management.
