Adapting a Generic Data Synchronisation Framework for YAWL to Access Clinical Information Systems at the Task Level

Abstract. Based on a generic extensible data access framework (DAF) [10], we devised a domain-specific extension to support interoperability of Yawl workflow cases with hospital information systems (HIS). In the scenario considered, the HIS is the principal system that keeps master data and clinical data of the patient. Data transfer between HIS and the Yawl runtime environment is facilitated via exchange of standardized HL7 messages. The solution presented supports read and write tasklevel synchronization of workflow variables using the patient’s case ID as correlation parameter. A first proof-of-concept has been carried out in a real clinical setting
