AI总结:

针对医院30天再入院预测,提出基于Transformer的PT模型,整合EHR、影像和临床笔记,兼具准确性、可扩展性和鲁棒性。

摘要:

医院再入院预测对于临床决策支持至关重要,旨在识别出院后30天内存在再入院风险的患者。高再入院率通常表明治疗或出院后护理不足,因此有效的预测模型对于优化资源和改善患者预后至关重要。我们提出PT,一种基于Transformer的模型,整合电子健康记录(EHR)、医学影像和临床笔记来预测30天全因医院再入院。PT从原始数据中提取特征,并使用针对数据复杂性定制的专用Transformer块。通过随机森林进行EHR特征选择以及测试时集成技术的增强,PT实现了优越的准确性、可扩展性和鲁棒性。即使缺少时间信息,它也能表现良好。我们的主要贡献是:(1)简洁性:一个强大且高效的基线模型,在预测准确性上优于现有模型;(2)可扩展性:灵活处理来自不同模态的各种特征,仅使用临床笔记或EHR数据即可实现高性能;(3)鲁棒性:即使时间数据缺失或不清晰,也能保持强大的预测性能。

英文摘要:

Hospital readmission prediction is critical for clinical decision support, aiming to identify patients at risk of returning within 30 days post-discharge. High readmission rates often indicate inadequate treatment or post-discharge care, making effective prediction models essential for optimizing resources and improving patient outcomes. We propose PT, a Transformer-based model that integrates Electronic Health Records (EHR), medical images, and clinical notes to predict 30-day all-cause hospital readmissions. PT extracts features from raw data and uses specialized Transformer blocks tailored to the data's complexity. Enhanced with Random Forest for EHR feature selection and test-time ensemble techniques, PT achieves superior accuracy, scalability, and robustness. It performs well even when temporal information is missing. Our main contributions are: (1)Simplicity: A powerful and efficient baseline model outperforming existing ones in prediction accuracy; (2)Scalability: Flexible handling of various features from different modalities, achieving high performance with just clinical notes or EHR data; (3)Robustness: Strong predictive performance even with missing or unclear temporal data.
