Many child health care providers find coordinating care to be an extremely time-consuming and complicated service for which they receive no reimbursement. Especially difficult is coordinating developmental services delivered by providers who work outside the health care system, such as early childhood educators. Some states and communities are addressing these problems by creating systems of care coordination that are designed to support both families and practitioners. While these innovative efforts are early in their development, they offer potentially successful approaches that others might adopt. This project will study and report on some of the most promising models in order to foster their spread and encourage further innovation.
