研究目的: |
主要目的: (1)开发一个基于常规急诊就诊数据的72小时高风险再就诊临床预测模型。 (2)通过时序验证方法评估模型的区分度和校准度。 次要目的: (1)比较传统Logistic回归与机器学习方法的预测效能。 (2)构建可视化列线图,并开发在线风险计算器供临床使用。 (3)识别与高风险再就诊相关的独立预测因素。 |

|
Objectives of Study: |
Primary Objectives:(1) To develop a 72-hour high-risk revisit clinical prediction model based on conventional emergency department visit data.(2) To evaluate the discrimination and calibration of the model using temporal validation methods.Secondary Objectives:(1) To compare the predictive performance of traditional Logistic regression and machine learning methods.(2) To construct a visualized nomogram and develop an online risk calculator for clinical application.(3) To identify independent predictive factors associated with high-risk revisit. |
