One of the fundamental goals of artificial intelligence is to build computer-based expert systems. Inferring clinical diagnoses to generate a clinical assessment during a patient encounter is a crucial step towards building a medical diagnostic system. Previous works were mainly based on either medical domain-specific knowledge, or patients' prior diagnoses and clinical encounters. In this paper, we propose a novel model for automated clinical assessment generation (MCAG). MCAG is built on an innovative graph neural network, where rich clinical knowledge is incorporated into an end-to-end corpus-learning system. Our evaluation results against physician generated gold standard show that MCAG significantly improves the BLEU and rouge score compared with competitive baseline models. Further, physicians' evaluation showed that MCAG could generate high-quality assessments.
人工智能的一个基本目标是构建基于计算机的专家系统。在患者就诊期间推断临床诊断以生成临床评估是构建医疗诊断系统的关键一步。先前的工作主要基于医学领域特定知识,或患者的既往诊断和临床就诊情况。在本文中,我们提出了一种用于自动生成临床评估的新型模型(MCAG)。MCAG基于一种创新的图神经网络构建,其中丰富的临床知识被整合到一个端到端的语料库学习系统中。我们针对医生生成的金标准的评估结果表明,与具有竞争力的基线模型相比,MCAG显著提高了BLEU和rouge分数。此外,医生的评估表明MCAG可以生成高质量的评估。
