Predictive Value of OASIS for Sepsis-associated Acute Kidney Injury: A Retrospective Cohort Study Based on the MIMIC-IV Database

Sepsis is a life-threatening and critical condition that often leads to multiple organ dysfunction. Among its complications, Sepsis-associated Acute Kidney Injury (SA-AKI) is a prevalent and fatal issue, resulting in numerous deaths worldwide each year. Early assessment of sepsis is crucial for reducing mortality rates. While scoring systems are commonly utilized in the intensive care setting, clinicians often favor simpler and more user-friendly tools. The Oxford Acute Severity of Illness Score (OASIS) provides a rapid evaluation of patient conditions. However, its predictive validity for SA-AKI has not been thoroughly investigated. This study aims to explore the predictive capability of OASIS for the development of SA-AKI in septic patients during hospitalization.
