Surveillance Data Lead

Overview

The surveillance of blood lead levels, particularly in children, is a critical component of public health efforts to prevent and manage lead poisoning. This overview outlines the key aspects of lead surveillance:

Data Collection and Reporting

• The Centers for Disease Control and Prevention (CDC) collects blood lead surveillance data through its Childhood Lead Poisoning Prevention Program.
• State and local health departments report data to the CDC, with some states mandated by CDC-funded cooperative agreements and others providing data voluntarily.
• Clinical laboratories are required by state laws to report all blood lead levels to state health departments.

National Surveillance System

• The CDC's Childhood Blood Lead Surveillance (CBLS) System integrates data from state and local health departments.
• The system applies consistent standard definitions and classifications, using rigorous error-checking and validation algorithms.
• Only one test per individual per year is counted in the CDC's data tables to ensure accuracy.

Blood Lead Reference Value (BLRV)

• The CDC uses the BLRV to identify children with higher levels of lead in their blood.
• As of 2021, the BLRV was updated to 3.5 μg/dL, based on data from the National Health and Nutrition Examination Survey (NHANES).
• This lower threshold allows for earlier identification and intervention.

Data Analysis and Limitations

• The collected data is primarily for program management purposes and has limitations.
• It is not a population-based estimate, and representativeness can vary across states and counties.
• Factors such as population size, number of children tested, and testing recommendations affect the percentages of children with higher blood lead levels.

State-Level Surveillance

• Each state maintains its own child-specific surveillance databases.
• These databases track blood lead levels, identify high-risk areas, and facilitate environmental investigations.
• Examples include Pennsylvania's PA-NEDSS and Minnesota's reporting system through the Minnesota Department of Health.

Improvements and Challenges

• Ongoing efforts aim to improve the efficiency and accuracy of data collection.
• Some states, like Michigan, are implementing new data reporting routes and using electronic health record (EHR) systems to streamline processes.

Public Health Actions

• The CDC recommends prioritizing medical and public health actions for children with blood lead levels at or above the BLRV.
