Abstract

The modeling of clinical data for Health Information Systems (HIS) requires domain expertise. Model-Driven Development (MDD) techniques provide a better articulation between domain experts and developers of HISes and enable the reduction in the develop ment cost of these systems. Clinical data models based on open standard specifications such as the openEHR facilitates the application of MDD techniques for HISes. Neverthe less, the use of clinical data models alone does not solve the fundamental problem of high development cost for HISes. One cause for this problem is the lack of architectural information in clinical data models. Without such architectural information, the develop ment cost is shifted to the specification of transformation rules from clinical data models to HIS code (these rules are fundamental in MDD techniques), since each new HIS to be generated involves the specification of a new set of rules. In this context, this work presents a strategy for code generation of HISes that combines clinical data models and architectural information. In this strategy, the developer is able to categorize HISes in distinct families and define a set of transformation rules that are common to all HISes in a family. Each family is defined by a set of systems with similar architectural structures and distinct clinical data models. The expected result of such a strategy is a better reuse of model transformation rules. This strategy is employed to achieve the main objective of this work, which is to design a transformation system for the automatic synthesis of graphical user interfaces (GUI) for HISes, considering openEHR specifications and some constructs present in architectural description languages (ADLs), such as Acme. As a proof of concept, this framework is applied to some HIS families.
