Risk Factors and Prognosis of Acute Kidney Injury in Hospitalised Sepsis Patients.

Abstract

This study aimed to analyse the risk factors and prognosis of sepsis complicated with acute kidney injury (AKI). The clinical data of 324 patients with sepsis in the nephrology department of our hospital from January 2022 to January 2023 were collected. A total of 188 patients with AKI were the occurrence group, and 136 patients without AKI were the non-occurrence group. The influencing factors and prognosis of sepsis complicated with AKI were analysed. We observed significant differences in Acute Physiology and Chronic Health Evaluation II (APACHE II), total length of hospital stay, Intensive Care Unit (ICU) stay, mechanical ventilation support, diabetes mellitus and urine volume >1500 mL between the two groups (p < 0.05). After a follow-up period of 1 month, 125 (66.49%) of 188 patients with sepsis complicated with AKI died, and 63 (33.51%) survived. The results of logistic regression analysis showed that Sequential Organ Failure Assessment (SOFA), APACHE II, mechanical ventilation support, diabetes, urine volume >1500 mL and serum creatinine were independent risk factors of sepsis complicated with AKI (p < 0.05). Moreover, SOFA, APACHE II, ICU admission days, mechanical ventilation support, serum creatinine and non-continuous renal replacement therapy were independent risk factors of death in patients with sepsis complicated with AKI (p < 0.05). SOFA, APACHE II, ICU admission days, mechanical ventilation support, serum creatinine and non-continuous renal replacement therapy may be the influencing factors leading to death in patients with sepsis complicated with AKI. Early clinical intervention should be performed.
