Two-level Authoring of Computer-Interpretable Guidelines Motivation • Clinical Practice Guidelines ( CPG ) assist practitioners and patients on decisions about appropriate healthcare • Clinical Decision Support Systems ( CDSS ) based on Computer Interpretable Guidelines ( CIG ) • CIG authoring is an interdisciplinary collaborative process: • Medical experts • Knowledge engineers • Proposal: two-level CIG authoring method . - 2 - David Buenestado, LSI Dpt. UPV/EHU. MIE2011, Oslo, Norway, 2011

Two-level Authoring of Computer-Interpretable Guidelines Background • Task-Network Model (TNM): • CIGs composed of tasks hierarchically organised . - 3 - David Buenestado, LSI Dpt. UPV/EHU. MIE2011, Oslo, Norway, 2011

Two-level Authoring of Computer-Interpretable Guidelines Background • Model-Driven Engineering (MDE): • Platform- independence and adaptability • CIG metamodel: basic components of CIGs • CIG editors obtained from metamodel . - 4 - David Buenestado, LSI Dpt. UPV/EHU. MIE2011, Oslo, Norway, 2011

Two-level Authoring of Computer-Interpretable Guidelines Method overview The output of the first level is the input of the second . - 5 - David Buenestado, LSI Dpt. UPV/EHU. MIE2011, Oslo, Norway, 2011

Two-level Authoring of Computer-Interpretable Guidelines First level: Medical expert • User-friendly graphical CIG editor • Model CIGs as graphs of tasks (no implementation details) • Search engines for complementary information : • Medical terminology (UMLS) • Bibliography (PubMed) • Evidence (Cochrane) • Drugs (PubChem, Vademecum – only in Spanish) . - 6 - David Buenestado, LSI Dpt.
