  • Transcript

    • 1. Representing clinical processes in XML process definition language (XPDL) Vojtech Huser, MD, PhD Luke Rasmussen Justin Starren, MD, PhD
    • 2. Why represent processes?
      • Processes (sequence of events or steps) are important in modeling many healthcare problems
        • Clinical guidelines
        • Quality improvement
        • Research
    • 3. Background
      • Workflow patterns 1
        • Evaluation of clinical guidelines formalisms 2
      • Reports on use of workflow technology in healthcare 3
        • Administrative processes
        • Clinical processes (QI, DSS)
      • Cross-industry use of Business Process Management Systems 4
      1 Russel (2006), Wohed (2007) 2 Peleg (2007), Mulyar(2007) 3 Haux (2003), Emanuelle (2007), Koetter (2007), Hess (2007), Panzarasa (2007), Quaglini (2000,2001,2008) 4 WfMC handbook (2001-2007) ProHealth 2008 ProHealth 2007
    • 4. What is XPDL?
      • XPDL= X ML P rocess D efinition L anguage
      • Standard in workflow technology (Business Process Management = BPM)
      • Workflow: The automation of a business process where information or tasks are passed from one participant to another for action, according to a set of procedural rules
      • Process definition: A network of activities and their relationships, criteria to indicate the start and termination of the process, and information about the individual activities, such as participants, associated IT applications and data, etc.
    • 5. Larger context of our work
      • Integrate a workflow engine into an EHR system
        • Customize the functionality using process flowcharts
        • Empower non-programmers to manage knowledge
      • RetroGuide project
        • Retrospective analysis of data using executable graphical flowchart
      • Process mining research
      Huser (2006, 2007, 2008, 2009) Haux(2003) RetroGuide
    • 6. Work presented today
      • Key question:
        • How robust are XPDL-compliant workflow editors in modeling clinical processes?
      • Specific focus:
        • Representing algorithmic knowledge
        • No human process activities
          • process consisting of steps for a robot who analyses EHR data
        • Both retrospective and prospective mode
    • 7.  
    • 8. Example of execution 0.9% of patients with high risk patients with subsequent MI
    • 9. Example of execution
    • 10. Example of execution
    • 11. Editors tested
      • Vendors
        • Enhydra workflow editor
        • Tibco
        • MS Visio with an XPDL plugin (Capevision)
      • Features
        • Non-expert view of a process
        • Flowcharting conventions
        • Implementation of the XPDL standard
    • 12. 1. MS Visio
    • 13. 1. MS Visio
    • 14. Two abnormal eGFR at least 90 days apart and no normal ones in between
    • 15. 2. Enhydra Editor Engine
    • 16. 3. Tibco
    • 17. Flowcharting differences Enhydra
    • 18. Flowcharting differences Tibco
    • 19. Results/Conclusions
      • Process definition languages represent a valid alternative to healthcare specific standards
      • Processes defined in XPDL can be shared across institutions
            • WfMC Compatibility levels
      • Several competing software workflow suites exist on the market
    • 20. Results/Conclusions
      • Differences in graphical representation of different XPDL features
    • 21. Thank you for you attention
