Background:The coexistence of acute kidney injury (AKI) in sepsis contributes significantly to morbidity and mortality rates. Traditional diagnostic markers still pose variable limitations in early AKI prediction. The use of renal angina index (RAI) as a clinical predictive tool for AKI is an emerging concept.

Objectives:To determine the diagnostic accuracy of RAI in predicting AKI in patients with sepsis

Methodology:This is a five-year retrospective cohort study conducted at the Philippine General Hospital (PGH). Records of eligible patients with sepsis were reviewed. RAI was calculated based on the composite of risk factors and clinical evidence of injury on day 0 of admission stratifying subjects into two groups: RAI (-) and RAI (+) for those with scores ≥ 8. Prediction of AKI with the RAI was analyzed.
