Healthcare enterprises involve complex processes involving clinical and administrative tasks that are supported by a variety of information and logistics systems. Although the workflow technology was introduced in various industries two decades ago, the use of Workflow Management Systems (WfMSs) is rather recent in the healthcare domain. This is due, in particular, by the fact that healthcare processes (or careflows) are highly flexible and extremely dynamic [1]. In this paper, we show how we can take advantage of description power of Recursive ECATNets for realizing flexible workflows in the healthcare domain.
