Display Omitted Introduces and demonstrates a new model-based design method that brings greater precision to the design of health IT.Design method extends workflow modeling with conceptual modeling of work products.Use of method in a multiple sclerosis clinic produces the Patient-Centered Case Management System.Usability evaluation indicates P-CMS is efficient and easy to use for case managers.Simulations of workflow models suggest P-CMS could save 18% of the time required for case management in the clinic studied. This paper introduces a new, model-based design method for interactive health information technology (IT) systems. This method extends workflow models with models of conceptual work products. When the health care work being modeled is substantially cognitive, tacit, and complex in nature, graphical workflow models can become too complex to be useful to designers. Conceptual models complement and simplify workflows by providing an explicit specification for the information product they must produce. We illustrate how conceptual work products can be modeled using standard software modeling language, which allows them to provide fundamental requirements for what the workflow must accomplish and the information that a new system should provide. Developers can use these specifications to envision how health IT could enable an effective cognitive strategy as a workflow with precise information requirements. We illustrate the new method with a study conducted in an outpatient multiple sclerosis (MS) clinic. This study shows specifically how the different phases of the method can be carried out, how the method allows for iteration across phases, and how the method generated a health IT design for case management of MS that is efficient and easy to use.
