In July of 1983, the state of Tennessee initiated The Healthy Children Initiative (HCI), a program designed to protect the health of Tennessee's children. Originally planned as a 4-year initiative, participating programs have been established on an ongoing basis. The first year's goal for Fiscal Year 83-84 was to make sure prenatal care was available for every pregnant woman in Tennessee. Another major area of emphasis has been the prevention of teenage pregnancies. The second and third years of the initiative concentrate on Infant Follow-Up (IFU), a program designed to insure that all babies receive developmental services and to establish networks between agencies and the private medical communities. This presentation describes the Infant Follow-Up Program designed for the Mid-Cumberland Region, an area consisting of 12 counties surrounding but not including the city of Nashville. The third year of the Healthy Children Initiative, which began July 1, 1985, focuses on expanding the Infant Follow-Up efforts to include a High Risk Registry to assure that infants with certain risk factors are identified systematically and followed with especially intensive efforts. Data indicate that the Follow-Up Program works: children have been assigned "medical homes," their immunization rate is better, and the medical communities are pleased. (RH)
