This guide is designed to help health care professionals and health care organizations implement collaborative, multidisciplinary team care for adults and children with diabetes in a variety of settings. Collaborative teams that provide continuous, supportive, and effective care for people with diabetes throughout the course of their disease are a model for the prevention and management of chronic diseases. Well-implemented diabetes team care can be cost-effective and the preferred method of care delivery, particularly when services include health promotion and disease prevention, in addition to intensive clinical management. Team care is a key component of health care reform initiatives that incorporate an integrated health care delivery system, especially those for chronic disease prevention and management.
