Description

Abstract: Critical limb ischemia (CLI) is a complication of advanced peripheral artery disease (PAD) with diagnosis based on the presence of clinical signs and symptoms. However, automated identification of cases is challenging due to absence of a single definitive International Classification of Diseases (ICD-9 or ICD-10) code for CLI. We extend a previously validated natural language processing (NLP) algorithm for PAD identification to develop and validate a subphenotyping NLP algorithm (CLI-NLP) for identification of CLI cases from clinical notes.

Learning Objective 1: Identification of Critical Limb Ischemia Cases from clinical notes using Natural Language Processing
