摘要:

护理的连续性对于确保从住院医院出院的患者获得积极的健康结果至关重要,改善信息共享可以提供帮助。为了共享信息,护理人员编写包含行动项目的出院记录,以与患者和他们未来的护理人员共享,但是由于文档的长度,这些行动项目很容易丢失。在这项工作中,我们描述了我们创建一个数据集的临床行动项目注释在MIMIC-III,最大的公开可用的数据集的真正的临床笔记。这个数据集,我们称之为CLIP,由医生注释,涵盖了代表10万个句子的718个文档。我们描述的任务,从这些文件中提取的行动项目作为多方面的提取摘要,每个方面代表一种类型的行动。我们评估了几个机器学习模型在这项任务中,并表明最好的模型利用域内语言模型预训练59 K无注释的文档,并结合从相邻的句子上下文。我们还提出了一种预训练数据选择的方法,使我们能够探索这个任务的预训练数据集的大小和域特异性之间的权衡。

英文摘要:

Continuity of care is crucial to ensuring positive health outcomes for patients discharged from an inpatient hospital setting, and improved information sharing can help. To share information, caregivers write discharge notes containing action items to share with patients and their future caregivers, but these action items are easily lost due to the lengthiness of the documents. In this work, we describe our creation of a dataset of clinical action items annotated over MIMIC-III, the largest publicly available dataset of real clinical notes. This dataset, which we call CLIP, is annotated by physicians and covers 718 documents representing 100K sentences. We describe the task of extracting the action items from these documents as multi-aspect extractive summarization, with each aspect representing a type of action to be taken. We evaluate several machine learning models on this task, and show that the best models exploit in-domain language model pre-training on 59K unannotated documents, and incorporate context from neighboring sentences. We also propose an approach to pre-training data selection that allows us to explore the trade-off between size and domain-specificity of pre-training datasets for this task.
