HHLPSS Data Management Platform

At a glance

The Healthy Homes and Lead Poisoning Surveillance System (HHLPSS) is a web-based data management platform developed and supported by CDC. It's used by state and local childhood lead poisoning prevention programs (CLPPPs) to provide a centralized surveillance repository. It includes blood lead data, environmental sampling results, and follow-up information for case management. Read more about HHLPSS.


HHLPSS is based on California's RASSCLE II system. The program was developed as part of a memorandum of understanding with the State of California.

HHLPSS replaced CDC's previous system STELLAR (Systematic Tracking of Elevated Lead Levels and Remediation). This application is deployed at the state or local level. CDC does not have access or control over the data entry, analysis, or reporting.

HHLPSS provides capabilities to assist state and local CLPPPs with improved workflow case management for tracking the following lead-related activities:

  • Collection of reported blood lead test results, including importing electronic laboratory records in HL7 format
  • Address standardization, validation, and geocoding
  • Identification and confirmation of children with elevated blood lead levels
  • Medical management of children with higher blood lead levels
  • Investigation and remediation of lead hazards in the home environment of children with higher blood lead levels
  • Generation of standardized reports and notification letters
  • Automated generation of quarterly surveillance extracts for submission to CDC
