Abstract

Background: Early detection of sepsis remains a critical challenge in intensive care. This study develops and validates a machine learning model for predicting sepsis onset up to 6 hours before clinical recognition. Methods: We collected data from 15,847 ICU admissions across five tertiary care centers. Features included vital signs, laboratory values, demographics, and clinical interventions recorded at hourly intervals. Results: The gradient boosting model achieved an area under the receiver operating characteristic curve (AUROC) of 0.94 (95% CI: 0.92-0.96) for sepsis prediction 6 hours before onset, with sensitivity of 87.3% and specificity of 91.2%. Conclusions: Our machine learning model demonstrates high accuracy for early sepsis prediction and has the potential to significantly improve patient outcomes through timely intervention.

Introduction

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Despite advances in critical care, sepsis remains associated with mortality rates of 25-30% in ICU settings.
