Presentation Transcript

  1. Introduction to workflow technology Representation of healthcare processes in a workflow editor and their execution in a workflow engine Vojtech Huser MD PhD AMIA NOW, Small Group session, Tutorial (1hr)

  2. Agenda • Part 1: Introduction, history, overview • Part 2: Standards, SDO, related theories • Part 3: Practical tools demonstration • Originally 2 hour workshop • converted to 1 hour tutorial (with focus on introduction and standards) • Accompanying bibliography document Vojtech Huser, MD, PhD

  3. Part 1: Introduction to workflow technology • Need for specifying workflow within IT systems • History of workflow technology • prior 1960s-1980s • development after 1990 • Components of workflow technology (process definition, execution engine, analytical components) • Benefits of implementing a workflow server within a generic IT system • Major workflow vendors and open-source workflow technology tools • Workflow Technology applied industries and healthcare • Future development and research challenges Vojtech Huser, MD, PhD

  4. Part 2: WT standards, SDOs, related theories • Workflow management coalition’s (WfMC) standards • Definition of WT terms • XML process definition language (XPDL) • Other standardization efforts • Business Process Execution Language (BPEL) • Business Process Modeling Notation (BPMN) • Research-originated WT standards • Petri Nets theory and its relationship to workflows Vojtech Huser, MD, PhD

  5. Part 3: Practical tools demos • Demo of an editor and engine • Example 1: • Representing a surgical procedure, discharge and RCT trial enrolment process • Example 2: • Two rheumatology decision support processes (TB screening, Pneumococcal vaccine) • Process mining tool (ProM) • Example 3: • Mining a progression of a chronic kidney disease from EHR data • Brief overview of other workflow technology software • Case studies of use in healthcare/informatics research • Workflow engines and Decision support engines Vojtech Huser, MD, PhD

  6. Part 1: Introduction to workflow technology • Need for specifying workflow within IT systems • History of workflow technology • prior 1960s-1980s • development after 1990 • Components of workflow technology (process definition, execution engine, analytical components) • Benefits of implementing a workflow server within a generic IT system • Major workflow vendors and open-source workflow technology tools • Workflow Technology applied industries and healthcare • Future development and research challenges Vojtech Huser, MD, PhD

  7. Workflow technology • BPM = business process management • Adaptive workflow (Adaptive Case Management) • Computer supported collaborative work (CSCW) • Why workflow? • Separation of data into databases • Separation of UI from IT system core • Separation of process knowledge Vojtech Huser, MD, PhD

  8. Process Example Koetter (2007) Vojtech Huser, MD, PhD

  10. Workflow patterns examples • Parallel Split: When an intrusion alarm is received, trigger the dispatch-patrol activity and the inform-police activity immediately. • Exclusive Choice: After the review election activity is complete, either the declare results or the recount votes activity is undertaken. • Multi Choice: Depending on the nature of the emergency call, one or more of the despatch-police, despatch-fire-engine and despatch-ambulance activities is immediately initiated.

  20. Terms • Workflow • The automation of a business process, in whole or part, during which documents, information or tasks are passed from one participant to another for action, according to a set of procedural rules. • WfMS = Workflow Management System • BPM = Business Process Management • BPMS = Business Process Management System Vojtech Huser, MD, PhD
