Making maintenance of the case-mix system user friendly

Introduction Maintaining and developing a case-mix system can be a complicated matter requiring years of experience, as well as extensive knowledge of the framework behind it. Because it is a complex task to maintain and develop the system, unintended effects or mistakes may arise from time to time. In addition, it can be difficult to communicate to users of the system what is required before a patient can be assigned to a specific case-mix group. To address these issues, a tool called VAGS (Visually Assisted Grouping System) has been developed in Denmark.
