Workflow management systems (WfMS) can be used to manage complex processes, such as those described by Clinical Practise Guidelines (CPG). Such processes involve a variety of stakeholders; however, frequently their interfaces are not suited to the needs of the stakeholders involved. Here we propose that WfMSs be integrated with tools to build a variety of interfaces to meet the needs of different users. Using a CPG for the management of hypertension as a case study, we give examples of user-friendly interfaces which can be built easily using our domain specific language, and which integrate with our WfMS. One interface guides the clinician in the management of the disease, allowing her/him the opportunity to view and interact with the process in a more holistic fashion, recording and recalling information relevant to the patient or the task. A second interface is more suited to the patient for the self management of lifestyle parameters, while other interfaces can be used by the patient, the clinician or the manager to represent trends or aggregate data.
