Beyond Flexibility - Workflows in the perioperative Sector of the Healthcare Domain Workshop on Flexible Workflows in Distributed Systems (WiVS 2011) Markus Bandt, Robert Kühn, Sebastian Schick, Holger Meyer Picture Source: Chris Caldwell, http://commons.wikimedia.org/wiki/File:Samcsurgery.jpg

PERIKLES – the Project  German acronym for “Unterstützung peri operativer klinischer Prozesse durch k ooperierende f le xible Workflows und AutoID- S ensorsysteme”  Executive Partners: Rostock University, ITSC, Gecko  Associated Partners:  UMC Rostock  KMG Klinik Güstrow  Hetzelstift Neustadt (Weinstraße)  UMC Köln  QUT Brisbane – BPM Group 2

PERIKLES – Goals  Support of perioperative clinical processes by cooperating flexible workflows and auto ID sensor systems  workflow-based assistance system to support the operating room management in a hospital  simplify common tasks  Scheduling  Coordinating  Communication  Tracking (process visualisation, statistical analysis) 3

Perioperative Process in Detail  perioperative process in a hospital includes all clinical workflows from admission of the patient on the ward, about the surgery, until the patient can leave hospital  Core process at the day of surgical treatment  „Slide show“ 4

Perioperative Process – Anaesthesia 7

Perioperative Process – Surgery 8

Perioperative Process – Reversal 9

Perioperative Process – Recovery 10

The Need for Flexibility  Why is flexibility so important in the health care sector?  Re-scheduling of a single task (e.g. change of diagnosis / method)  Predictable emergency situations (e.g. emergency treatment, transplantation treatment)  Unpredictable situations (demand of additional or sudden lack of ressources, deterioration of patients conditions, disaster situations)  etc. 13

Structural Perspective on Flexibility  What kind of (flexible) activities are prevalent here?  Parallel activities  Partially ordered activities  Optional activities  Alternative activities  Synchronisation of activities  Cancellation of activities 14

Flexibility Concepts – Summary The patterns in the table refer to the definitions of the Workflow Patterns Initiative ( http://www.workflowpatterns.com/ ). 15

Implementation – YAWL  YAWL asWfMS of choice  Open Source Framework with formal foundation  Well documented  Extendable through WS-Interface  Good, productive contact with developers 16

Example: Induction /partial order Legend (YAWL Elements) : 17

Example: Re-scheduling / expected exception 18

Conclusion  YAWL as tracking system  Some flexibility concepts limited  Stability and maintenance costs vs. Flexibilty  Successful evaluation with stakeholders  To-do:  Evaluation of combining different WfMS to gather advantages (incl. cost benefit analysis)  Handling unpredictable exceptions / ad-hoc processing 19
