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

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)

Results and future work

  • 3 CIGs developed on child asthma and

hyperammonemia using this method

  • Accesible through e-GuidesMed guidelines execution

portal (www.e-guidesmed.ehu.es)

  • Improvement in the collaborative process of CIG

authoring and quality of CIGs

  • Near future: implementation of protocols in primary

health care and for educational purposes
