Abstract

The Chicago Lead Poisoning and Prevention Program (CLPPP) implemented an early intervention program for infants between the age of 6 to 12 months with blood lead levels between 5 and 9 μg/dl. Infants that receive the same environmental and case management services as children with blood lead levels ≥ 10μg/dl is a powerful method of addressing childhood lead poisoning.

Purpose: The Chicago CLPPP has a primary objective to reduce the number of infants who progress to have blood lead levels ≥ 10μg/dl by 12 months of age by ensuring environmental and case management services are delivered. However, there has been no comparative assessment of this approach, either in terms of affecting case reduction, or in terms of effectiveness of the intervention.

Method: A comparative analysis was made on two different lead data groups reported to and recorded by the Chicago Department of Public Health, Lead Poisoning Prevention Program and the Center for Disease Control and Prevention, Healthy Homes and Lead Poisoning Prevention Program. This comparison was performed with strict attention to childhood blood lead level data and case and environment management measures performed. To help with comparability between the two datasets, the determination as to level of follow-up versus no follow-up was established as the standard used for measure within this study design.

Results: Blood lead test data of children with blood lead levels of 5 to 9 µg/dl were assessed, analyzing the results of those that saw an increase in there BLL, compared to those that saw a decrease based on an early intervention approach of including an environmental assessment apart of the initial case management visit. It is believed that the intervention would reduce the number of cases of lead poisoning, as well as reduce the number of children's blood lead levels from rising to the now removed level of concern of ≥ 10µg/dl.

Conclusion: The analysis indicated that blood lead test data of children with BLL of 5 to 9 µg/dl saw a significant reduction in their blood lead levels after receiving an environment home assessment along with initial case management visit.
