This summary report from a 3-year research and demonstration project describes the framework, methods and materials used by the University of Michigan-Ann Arbor Early Periodic Screening Diagnosis and Treatment (EPSDT) Day Care Project. The project served approximately 750 children and their families through day care centers and family day care homes in Washtenaw County, Michigan. The project developed a comprehensive and interdisciplinary approach to early health assessment and follow-through for children and training and consultation services for day care staffs. This approach involved adaptations of the EPSDT model and included on-site developmental assessment for each child served. Generally, the project demonstrated a means of enhancing preventive health care for young children by emphasizing the primary support day care centers can provide for families through promoting coordination of local resources for families using day care.
