BPM in healthcare
From workflow to careflow Workflow Management (WFM) and BusinessProcess Management (BPM) are widely applied inadministrative processes but not in healthcare. Increasingly, clinical decisions need to be based onscientific evidence, social-ethical values andeconomic factors. Evidence-based care requires transparency,justification, and accountability. Careflow processes need to be supported,controlled, and monitored.
Medical protocols Also named medical guidelines (to emphasizesupport) or pathways (to emphasize prediction).protocolsactionassess and refineprotocolprotocol selectionand customizationprotocolmeasurepatient data

Medical protocols Existing languages for describing medicalprotocols, guidelines and/or pathways: Asbru,EON, GLIF, GUIDE, PRODIGY and PROforma. Use of the protocols:– Passive: used to check afterwards– Active: used to “control” the careflow BPM software/research supports both uses:– Passive: process mining tools– Active: workflow management systems

Challenges for the next 25 years
Challenges Realize what has been promised in the last 25years .– Design support– Verification, validation and performance analysis– Cross-organizational workflow support– More flexibility (case handling)– Better management information (process mining)– These challenges also apply to careflow!
Process mining
Process mining: Reversing the ctcustomer Process mining can be used for:– Process discovery (What is the process?)– Delta analysis (Are we doing what was specified?)– Performance analysis (How can we improve?)www.processmining.o

Conclusion
lementation/configurationCareflow is an interesting but also challenging applicationdomain for BPM/WFM technology.It is important to close the BPM loop. Process mining is oneway to do this.Process mining provides many interesting challenges forscientists, customers, users, managers, consultants, and tooldevelopers.Process mining is particularly interesting in the healthcaredomain (cf. evidence-based medicine, increasedaccountability, and need to cut costs).
