摘要:

电子健康记录(EHR)的有意义的使用在数字时代继续取得进展,临床决策支持系统得到了人工智能的增强。改善提供者体验的优先事项是克服信息过载并减少认知负担,以便在患者护理期间引入更少的医疗错误和认知偏见。一种主要类型的医疗错误是诊断错误,这是由于依赖于诊断学的判断中的系统性或可预测性错误。尚未研究临床自然语言处理(cNLP)通过从数据到诊断的正向推理对人类诊断推理进行建模并潜在地减少认知负担和医疗错误的潜力。现有的任务,以促进科学的cNLP主要集中在信息抽取和命名实体识别通过分类任务。我们引入了一套新的任务,称为诊断推理基准,DR.BENCH,作为开发和评估具有临床诊断推理能力的cNLP模型的新基准。该套件包括来自10个公开数据集的六个任务,解决临床文本理解,医学知识推理和诊断生成。DR.BENCH是第一个临床任务套件,旨在成为一个自然语言生成框架,以评估预训练的语言模型。使用大型通用领域模型和在医学语料库上持续训练的模型对最先进的预训练生成语言模型进行实验,证明在DR. BENCH中进行评估时有改进的机会。我们将DR.BENCH作为一个公开可用的GitLab存储库进行共享,并采用系统化的方法为cNLP社区加载和评估模型。

英文摘要:

The meaningful use of electronic health records (EHR) continues to progress in the digital era with clinical decision support systems augmented by artificial intelligence. A priority in improving provider experience is to overcome information overload and reduce the cognitive burden so fewer medical errors and cognitive biases are introduced during patient care. One major type of medical error is diagnostic error due to systematic or predictable errors in judgment that rely on heuristics. The potential for clinical natural language processing (cNLP) to model diagnostic reasoning in humans with forward reasoning from data to diagnosis and potentially reduce the cognitive burden and medical error has not been investigated. Existing tasks to advance the science in cNLP have largely focused on information extraction and named entity recognition through classification tasks. We introduce a novel suite of tasks coined as Diagnostic Reasoning Benchmarks, DR.BENCH, as a new benchmark for developing and evaluating cNLP models with clinical diagnostic reasoning ability. The suite includes six tasks from ten publicly available datasets addressing clinical text understanding, medical knowledge reasoning, and diagnosis generation. DR.BENCH is the first clinical suite of tasks designed to be a natural language generation framework to evaluate pre-trained language models. Experiments with state-of-the-art pre-trained generative language models using large general domain models and models that were continually trained on a medical corpus demonstrate opportunities for improvement when evaluated in DR. BENCH. We share DR. BENCH as a publicly available GitLab repository with a systematic approach to load and evaluate models for the cNLP community.
