Presentation Transcript

  1. EviCare (NLP) • Aid clinical work in hospitals using NLP: • “Summarize” health records • Select and rank recommendations from clinical practice guidelines • (Semi-)automatically • Intended as possible extensions to EHR systems • DIPS ASA, partner in EviCare

  2. “Summarize” health records Goal: • Assist clinicians in getting an quick overview of the content in a health record (at the “point-of-care”) How: • Present a subset of the text by using methods from the field of automatic text summarization • Textual extracts with central information from one or more clinical notes • User-guided • Represents a possible interface for further search/navigation in the clinical notes by the user • Visualization (e.g. timeline)

  3. “Summarize” health records (cont.) • Mainly statistical based methods • Supplied with domain knowledge: • Now: Medical/clinical dictionaries • (linked to MeSH, SNOMED-CT) • Later: Task specific annotations & C2PO • Knowledge-poor  knowledge-rich

  4. Select and rank recommendations from clinical practice guidelines Goal: • Present one or more (ranked) recommendations based on the content in a health record How: • Use the “summaries” as search query, or context for the search query, to the guideline repositories

  5. Select and rank recommendations from clinical practice guidelines (cont.) • Regexp based search mixed with statistical based methods for doing information retrieval/extraction • Attempt to rank the various sections in the guidelines according to: • only the content selected by the summary (i.e. previous medical history), or • free-text search by the user, applying the summary content as context • Mono-/cross-lingual • Cross-domain (?)
