About OLGA

• Project Online Guideline Assist OLGA
• 3 year research project sponsored by the German
  Research Council DFG
• Goal Measure the effects of automated,
  integrated guideline support in an ICU
• Operational guideline support within the PDMS
• Build upon existing technologies
• Use an agile approach
• Measure effect of automated guidelines
• Criteria for automating guidelines

Approach

• Focus on operational system
• No preference towards GL methodology
• No preference towards workflow technology
• No preference towards technical systems
• Approach
• Look into computerized clinical guideline
  standards
• Look into workflow systems
• Look into existing (paper-based) SOPs
• Select promising candidates and just start
• Guideline Interchange Format GLIF
• jBPM Workflow Framework (jBOSS)
• Example guidelines
• Improve and extend over time
