A Sepsis Mortality Risk Prediction Model Based on Multi-feature Federated Learning

中文摘要英文摘要

脓毒症是一种由感染而引起的全身炎症反应综合症,在重症监护病房中具有较高的死亡率.然而,现有的预测方法通常依赖于从特征集合中提取单一特征子集,未能充分利用特征子集之间的复杂关联性,即结构互信息,从而限制了预测准确性.结构互信息不仅衡量了同一粒度下特征之间的依赖性,还揭示了不同粒度下特征之间的复杂关系,使其能够更精确地捕捉病情的细微变化.为了解决这一问题,本文提出了一种新的脓毒症预后模型,通过深入挖掘电子病历中的结构互信息,以显著提高死亡风险预测的准确性.实验结果表明,本文的预后模型在预测准确性方面表现出显著优势,为临床医生提供了更可靠的死亡风险评估和明确的决策支持.

Sepsis refers to a systemic inflammatory response resulting from infections,and it carries a high risk of mortality in intensive care settings.Existing predictive models often rely on extracting single feature subsets from a larger set,failing to fully utilize the complex interactions between feature subsets,known as structural mutual information.This limitation reduces prediction accuracy.Structural mutual information not only captures dependencies between features at the same level of granularity but also reveals complex relationships across different granularities,enabling more precise detection of subtle changes in a patient's condition.To address this limitation,this study presents a novel sepsis prognosis model that deeply explores the structural mutual information within electronic health records,significantly enhancing the accuracy of mortality risk predictions.Experimental results show that the proposed model achieves notable improvements in predictive accuracy,providing clinicians with more dependable mortality risk assessments and clearer decision-making support.
