From 2006 to 2010, Medicaid health care providers received an annual Blood Lead Testing Report. These reports were developed through collaboration with the Wisconsin Medicaid Program and the Wisconsin Childhood Lead Poisoning Prevention Program. The individualized reports summarize the blood lead testing data for children under age 6 within each provider's practice. In addition, providers received a list of untested children in their practice to facilitate follow-up to ensure these children get tested.
Children enrolled in Medicaid are required to have a blood lead test at ages 1 and 2 and, if not tested at these ages, they must receive at least one test between the ages of 3 to 5. Many Medicaid children do not receive a blood lead test at the appropriate ages.
The report was developed to help more of these children get the tests they deserve. For the first time since 2007, there was a significant increase in the number of children tested (Figure 2) in 2009, from approximately 80,000 per year to over 100,000 children tested. The result of testing more children that are required to be tested was a leveling out of the number of children found to be poisoned (Figure 1), which had been on a steady decline.
