Abstract:
The mission of the Multiple Sclerosis Centers of Excellence (MSCoEs) is to optimize the services veterans with multiple sclerosis (MS) receive across the U.S. Veterans Health Administration. To accomplish this mission, the MSCoE West has adopted a collaborative chronic-disease management strategy along the lines of the model described by Wagner and colleagues. This model describes an organized, integrated, proactive, and population-based approach to patient care that includes healthcare delivery system change and patient-based self-management. While Wagner's model is described independent of information technology, the majority of actions called for in that model benefit tremendously from the application of a powerful and well-integrated informatics infrastructure designed to serve and support populations with chronic disease. Key elements such as goals and actions encourage high-quality care for those with chronic illnesses.

Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...
