EURODIABETA was one of the largest (16 partners, 3 sub-contractors, from 7 EC member states) AIM funded projects bringing European experts together to perform a feasibility study on the production of a Computer assisted Chronic Health Care Environment to support diabetes care as a paradigm of all chronic disease care. Good project management has demonstrated the viability of such an ambitious goal. Existing prototypes have been evaluated as components for an integrated system, and conceptual modelling has been identified as a means for providing the logical framework within which the components will fit.
