Enterprise AI Analysis: Research Paper
Explainable AI unravels sepsis heterogeneity via coagulation-inflammation profiles for prognosis and stratification
This research developed an explainable artificial intelligence (XAI) model (SepsisFormer) and an automated risk-stratification tool (SMART) to address sepsis heterogeneity. In a multi-center study of 12,408 patients, SepsisFormer achieved high predictive accuracy (AUC: 0.9301). SMART (AUC: 0.7360) surpassed most established scoring systems. Seven coagulation-inflammatory routine laboratory measurements and patient age were identified to classify patients into four risk levels (mild, moderate, severe, dangerous) and two subphenotypes (CIS1 and CIS2). Notably, patients with moderate/severe levels or CIS2 showed significant benefits from anticoagulant treatment. This work provides simple, real-time tools for sepsis management, particularly in resource-constrained settings.

This category focuses on the development and validation of AI models for predicting sepsis outcomes, comparing their performance against traditional methods and assessing their generalizability across different datasets.
This section delves into how AI models reveal the importance of specific markers, like coagulation-inflammatory indicators and patient age, in sepsis diagnosis, prognosis, and subtyping through multi-view analyses (EHR, model, and transcriptomic levels).
This category explores the identification of distinct sepsis subphenotypes (CIS1 and CIS2) and risk stratification levels, examining their unique clinical characteristics, mortality rates, and varied responses to treatments such as anticoagulation.
SepsisFormer's Predictive Accuracy
0.9301 AUC (Area Under the Curve)SepsisFormer, a transformer-based neural network, achieved an impressive AUC of 0.9301 in predicting sepsis outcomes, demonstrating superior performance compared to traditional machine learning and deep learning models across multi-center cohorts.

SMART demonstrates superior predictive accuracy in local ICU cohorts compared to several established sepsis scoring systems, offering automated risk stratification based on a minimal set of routine measurements.
Critical Markers for Sepsis Management
8 Key Coagulation-Inflammatory Markers + AgeEight markers (APTT, INR, lymphocytes, monocytes, neutrophils, WBC, PLT counts, and patient age) were identified as crucial for predicting sepsis prognosis, identifying subphenotypes, and guiding treatment.
Anticoagulant Treatment Efficacy in Heterogeneous Sepsis
Scenario: In a study of 4191 sepsis patients, patients with moderate/severe risk levels or belonging to the CIS2 subphenotype showed significant benefits from anticoagulant treatment (heparin).
Key Results:
- ✓Moderate-level patients: 28-day mortality reduced (HR: 0.60, p<0.005)
- ✓Severe-level patients: 28-day mortality reduced (HR: 0.57, p<0.005)
- ✓CIS2 subphenotype: 28-day mortality reduced (HR: 0.42, p<0.005), indicating greater benefit for this high-risk group.
Implication: Tailored anticoagulant therapy, guided by risk stratification and subphenotyping, can significantly improve outcomes for specific sepsis patient groups, enhancing safety and precision in decision-making.
This case study highlights the heterogeneous treatment effects (HTEs) in sepsis, specifically demonstrating how anticoagulant therapy provides significant survival benefits for patients in higher risk categories or the CIS2 subphenotype, underscoring the value of personalized treatment strategies.
