Development and Validation of a Clinical Risk Prediction Model for Early Acute Kidney Injury Within 48 Hours After Liver Transplantation

Completed

• Conditions: Acute Kidney Injury; Liver Transplantation; Model

• Registration Number: NCT06750770
• Lead Sponsor: Beijing Tsinghua Chang Gung Hospital

Brief Summary

Acute kidney injury (AKI) is a common complication after liver transplantation, with an incidence of 12.7-95%. The occurrence of acute kidney injury after transplantation is related to the poor prognosis of patients, which significantly increases the length of hospital stay, hospitalization costs and mortality of patients. Early recognition of acute kidney injury after transplantation is of great significance. Therefore, by collecting preoperative and intraoperative variables, this study intends to establish and verify a clinical risk prediction model for early AKI after liver transplantation, in order to provide clinicians with a visual prediction tool to identify patients with high risk of early AKI after liver transplantation immediately after the operation, so as to start clinical intervention as soon as possible and improve the prognosis of patients.

Primary Outcome Measures

Name	Time	Method
KDIGO criteria (Kidney Disease: Improving Global Outcomes) used to evaluate postoperative AKI in liver transplant patients.	48 hours post-surgery	Diagnosed according to 2012 KDIGO criteria: serum creatinine rise ≥50% or ≥26.5 µmol/L within 48 hours post-surgery. Baseline creatinine was the most recent preoperative value, with kidney function assessed by eGFR.
