AI总结:

本研究利用MIMIC-IV数据集验证基于希腊医院本地数据训练的急诊入院预测模型,发现随机森林(RF)表现最优(AUC-ROC 0.9999),并确立MIMIC-IV作为验证小样本模型的有效基准。

摘要:

急诊科(ED)拥挤的有效管理对于改善患者预后和优化医疗资源配置至关重要。本研究利用全面的MIMIC-IV数据集,验证了最初基于希腊一家医院的小型本地数据集开发的入院预测模型。在对MIMIC-IV数据进行预处理后,评估了五种算法:线性判别分析(LDA)、K近邻(KNN)、随机森林(RF)、递归划分与回归树(RPART)以及支持向量机(SVM径向基)。其中,RF表现出优越的性能,应用于MIMIC-IV数据时,受试者工作特征曲线下面积(AUC-ROC)达到0.9999,灵敏度为0.9997,特异度为0.9999。这些发现凸显了RF在处理复杂数据集进行入院预测方面的稳健性,确立了MIMIC-IV作为验证基于较小本地数据集模型的有价值基准,并为改进急诊科管理策略提供了可操作的见解。

英文摘要:

The effective management of Emergency Department (ED) overcrowding is essential for improving patient outcomes and optimizing healthcare resource allocation. This study validates hospital admission prediction models initially developed using a small local dataset from a Greek hospital by leveraging the comprehensive MIMIC-IV dataset. After preprocessing the MIMIC-IV data, five algorithms were evaluated: Linear Discriminant Analysis (LDA), K-Nearest Neighbors (KNN), Random Forest (RF), Recursive Partitioning and Regression Trees (RPART), and Support Vector Machines (SVM Radial). Among these, RF demonstrated superior performance, achieving an Area Under the Receiver Operating Characteristic Curve (AUC-ROC) of 0.9999, sensitivity of 0.9997, and specificity of 0.9999 when applied to the MIMIC-IV data. These findings highlight the robustness of RF in handling complex datasets for admission prediction, establish MIMIC-IV as a valuable benchmark for validating models based on smaller local datasets, and provide actionable insights for improving ED management strategies.
