Abstract:
Building a predictive model to understand a patient's status and the future progression of disease is an important precondition for facilitating preventive care to reduce the burden of chronic obstructive pulmonary disease. Recently, unsupervised feature learning has become the dominant approach to predictive modeling based on EMRs (electronic medical records), which usually adopts word and concept embeddings as distributed representations of clinical data. By observing that (1) semantic discrimination is limited by the inherent small feature granularity of words and concepts and (2) clinical decision-making is conducted based on a set of attribute-value pairs, e.g., a clinical laboratory test (the attribute) with a numerical or categorical value, this paper proposes a novel predictive modeling approach based on EMRs. In this approach, multi-granular features, i.e., words, concepts, concept relations and attribute-value pairs, are extracted through three subtasks (concept recognition, relation extraction and attribute-value pair extraction), then, combined to derive representations and predictive models of chronic obstructive pulmonary disease (COPD). The approach itself is highly generic, it can be used for different disease, but limited in Chinese EMRs. In this paper, we focus on the COPD risk prediction, and conduct extensive experiments on real-world datasets for a comparison study. The results show that our approach outperforms baselines, which demonstrates the effectiveness of the proposed model.
