About OLGA
Project: Online Guideline Assist – OLGA· 3 year research project sponsored by the German Research Council DFG
Goal: Measure the effects of automated, integratedguideline 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

Summary
Work in progress
Agile, iterative approach
Focus: operational guideline execution within PDMS· Utilization of existing technologies
Workbench: Olga Shell· Formalizing process knowledge· Convert existing guidelines· Simulation and execution
Evaluation of effects of automated guideline support· Starting end of year with tests· 1 year daily life evaluation in ICU
