Leveraging Knowledge from Clinical Guidelines through Information Technologies

e-Knowledge Gateway

• Clinical Practice Guideline (CPG)• systematically developed statements to assist

practitioner and patient decisions about appropriate health care for specific clinical circumstances

• repositories of knowledge about ideal practice

• e-Knowledge Gateway (eKG)• a knowledge portal to support evidence-based clinical

practice

Guideline Comparison

Selective dissemination to pathologist

e-Knowledge Gateway

• Web resources and services integration through metadata, meta-thesaurus, XML environments– Cross platform/system retrieval

– Knowledge generation through discussion

– Targeted and flexible display and dissemination

• Guideline cycle and development process support– Systematic and supplementary search using profiles

– Link recommendation explicitly with evidence

– Prompt developer for revision on new evidence

Summary

e-Knowledge Gateway

• Guideline life cycle sustained through eKG integrated web services

• Scope for integrating queries from clinical systems for decision support
