Core Tip

Core Tip: Acute kidney injury (AKI) is a relatively common complication after liver surgery and has a negative impact on long-term patient prognosis. Early detection and timely intervention are key in order to minimize the negative impact of AKI. Machine learning has become increasingly better integrated with clinical medicine. In our retrospective study, we established a real-time prediction model based on machine learning algorithms. The final models showed high power to discriminate AKI events.
