The tracking system covers the five central counties in the metropolitan Atlanta area: Clayton, Cobb, DeKalb, Fulton, and
Gwinnett. Metropolitan Atlanta has an estimated population of 2.9 million and an
estimated 50,000 births per year. The population has changed with the growth of
Atlanta since the beginning of the study. Atlanta has become more urban and the
racial and ethnic make-up has changed over time. Since MACDP began tracking
birth defects in Atlanta, the percentage of births to non-whites has risen from
27% to 48%.
The key to the success of MACDP has been its many case sources. A passive
tracking system, which relies on voluntary reporting, would miss many birth
defects. The specially trained MACDP staff, on the other hand, visits hospitals
and clinics throughout the metropolitan Atlanta area to make certain that all
births affected by a birth defect are included. MACDP also links with other
databases such as birth and death certificates and genetic laboratories. Data
linkage among the various databases broadens the information, improves
ascertainment, helps prevent counting the same baby with a birth defect twice,
and improves the overall quality of the data. |
