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
