The study by researchers found inconsistencies across demographics, allergies, procedures, diagnoses, laboratory, medications, and care-planning domains, but expert review identified recurring failure modes involving temporal reasoning, evolving-diagnosis context, and outpatient-prescribing conventions.", "body_md": "arXiv:2607.22954v1 Announce Type: new\nAbstract: Objective: To characterize the kinds of internal documentation inconsistencies a general-domain large language model (LLM) can surface from real-world discharge summaries, and to identify recurring failure modes that limit reliability at scale.\nMaterials and Methods: We applied a two-stage LLM pipeline---open-ended candidate identification (Gemini 2.5 Pro) followed by context-grounded verification (Gemini 2.5 Flash)---to 3,000 randomly sampled MIMIC-IV-Note discharge summaries. A subset of the pipeline output was then reviewed manually by clinical experts.\nResults: Our pipeline surfaced 3,460 candidate inconsistencies, affecting 69.7% of admissions. Representative examples spanned demographics, allergies, procedures, diagnoses, laboratory, medications, and care-planning domains, with direct implications for clinical reasoning or patient safety. Expert review also revealed recurring failure modes that arise when verification requires temporal reasoning, evolving-diagnosis context, or knowledge of outpatient-prescribing conventions the model does not natively possess.\nDiscussion: Detection is highly context-dependent: many flagged pairs require anchoring each statement to its source section and clinical domain, then assessing whether the conflict reflects a true contradiction or missing context. We propose a graded ontology spanning strict contradiction and ambiguity, with a schema characterizing each flagged case by category, section, domain, and inconsistency axis.\nConclusion: This formative study establishes a methodological foundation and conceptual framework to guide subsequent validated, large-scale EHR-inconsistency analysis.", "url": "https://wpnews.pro/news/toward-automated-detection-of-documentation-inconsistencies-in-electronic-health", "canonical_source": "https://arxiv.org/abs/2607.22954", "published_at": "2026-07-28 04:00:00+00:00", "updated_at": "2026-07-28 04:25:42.120131+00:00", "lang": "en", "topics": ["large-language-models", "artificial-intelligence", "natural-language-processing", "ai-research"], "entities": ["Gemini 2.5 Pro", "Gemini 2.5 Flash", "MIMIC-IV-Note", "arXiv"], "alternates": {"html": "https://wpnews.pro/news/toward-automated-detection-of-documentation-inconsistencies-in-electronic-health", "markdown": "https://wpnews.pro/news/toward-automated-detection-of-documentation-inconsistencies-in-electronic-health.md", "text": "https://wpnews.pro/news/toward-automated-detection-of-documentation-inconsistencies-in-electronic-health.txt", "jsonld": "https://wpnews.pro/news/toward-automated-detection-of-documentation-inconsistencies-in-electronic-health.jsonld"}}
