Clinicians often populate new documents by duplicating existing notes, then updating accordingly. Data duplication can lead to a propagation of errors, inconsistencies and misreporting of care. Therefore, quantifying information redundancy can play an essential role in evaluating innovations that operate on clinical narratives. This work is a quantitative examination of information redundancy in EHR notes. We present and evaluate two strategies to measure redundancy: an information-theoretic approach and a lexicosyntactic and semantic model. We evaluate the measures by training large Transformer-based language models using clinical text from a large openly available US-based ICU dataset and a large multi-site UK based Trust. By comparing the information-theoretic content of the trained models with open-domain language models, the language models trained using clinical text have shown ~1.5x to ~3x less efficient than open-domain corpora. Manual evaluation shows a high correlation with lexicosyntactic and semantic redundancy, with averages ~43 to ~65%.","url_abs":"https://arxiv.org/abs/2105.11832v2","url_pdf":"https://arxiv.org/pdf/2105.11832v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"estimating-redundancy-in-clinical-text","repo_url":"https://github.com/tomolopolis/clinical_sum","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"pytorch","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
