Diabetic healthcare is characterized by the collaboration problem, which is manifested by problems of accessibility and interoperability. To improve the problem situation, we propose a Multi-agent Systems approach. The interactions among the diabetic healthcare actors are categorized on three levels: collaboration, coordination, and communication. Agents are designed to work on the coordination and communication levels, and support the collaboration among human actors. This paper presents a project Integrated Mobile Information Systems for diabetic healthcare (IMIS) to demonstrate how to apply Multi-agent Systems coordination to the collaboration among healthcare actors.
