脓毒症是全球每年影响超过4890万例、导致1100万人死亡的危及生命的疾病。尽管医疗技术进步，其预测仍因症状非特异和病理机制复杂而困难。本文提出的SXI++ LNM是一种机器学习评分系统，通过整合多种算法与深度神经网络，提升临床应用中的鲁棒性。模型在不同数据分布条件下进行训练与测试，基于未见过的测试数据评估性能，计算准确率、精确率和曲线下面积（AUC）。在三个使用场景中，SXI++ LNM均超越当前最优水平，达到AUC 0.99（95%置信区间：0.98–1.00），精确率99.9%（95%置信区间：99.8–100.0），准确率99.99%（95%置信区间：99.98–100.0），展现出极高的可靠性。
原文摘要 · Abstract (English)
Sepsis is a life-threatening condition affecting over 48.9 million people globally and causing 11 million deaths annually. Despite medical advancements, predicting sepsis remains a challenge due to non-specific symptoms and complex pathophysiology. The SXI++ LNM is a machine learning scoring system that refines sepsis prediction by leveraging multiple algorithms and deep neural networks. This study aims to improve robustness in clinical applications and evaluates the predictive performance of the SXI++ LNM for sepsis prediction. The model, utilizing a deep neural network, was trained and tested using multiple scenarios with different dataset distributions. The model's performance was assessed against unseen test data, and accuracy, precision, and area under the curve (AUC) were calculated. THE SXI++ LNM outperformed the state of the art in three use cases, achieving an AUC of 0.99 (95% CI: 0.98-1.00). The model demonstrated a precision of 99.9% (95% CI: 99.8-100.0) and an accuracy of 99.99% (95% CI: 99.98-100.0), maintaining high reliability.
