STELLAR is a software application provided free of charge by the Centers of Disease Control (CDC) to State and local Childhood Lead Poisoning Prevention Programs (CLPPPs) with a practical means of tracking medical and environmental activities in lead poisoning cases. The intent of this application is to provide an electronic means of storing childhood lead exposures, medical, and laboratory data that the state program receives from labs, providers, clinics, parents, and local health departments. In Oregon, STELLAR is a database that contains all childhood blood lead tests from 1991 to present. While the focus is children, the file does contain data and information on adults. Data and information comes from all clinical laboratories known to the Oregon Childhood Lead Poisoning Program. Data and information is transmitted by mail and fax, and electronic records are through Oregon’s National Electronic Disease Surveillance System - Electronic Lab Reporting (NEDSS-ELR) project.
The purpose of the Oregon Childhood Lead Poisoning Prevention Program (OCLPPP) is to eliminate childhood lead poisoning as a public health problem by 2010. The purpose of STELLAR is to have a repository for all blood lead tests in Oregon and a lead poisoning case management system.
Unfortunately, risk factors for exposure to lead hazards are still relatively common in many parts of the US. Two major factors place children at higher risk for lead poisoning, living in poverty and living in older housing (primarily pre-1950). According to the National Health and Nutrition Examination Survey NHANES III, Part 2, poor children were four times as likely to have elevated blood lead levels (EBLLs) as middle income children and eight times as likely as high income children. In the same survey, children living in pre-1946 housing were five times as likely to have EBLLs as children living in housing built after 1973. To make the problem worse, we know that poor children tend to live in older housing.
As of time period end date
Before the release of any data, all research proposals requesting the use of confidential lead test data must be reviewed by Oregon Department of Human Services, State Public Health Division for compliance with the following criteria: 1) Proposed research will be used to determine elevated blood lead levels, focus additional testing for Oregon residents, and reduce the burden of elevated blood lead levels; 2) Data requested are necessary for the efficient conduct of the study; 3) Adequate protections are in place to provide secure conditions to use and store the data; 4) Assurances are given that the data will only be used for the purposes of the study, and assurances that confidential data will be destroyed at the conclusion of the study; 5) Researcher(s) have adequate resources to carry out the proposed research; 6) Research proposal has been reviewed and approved by the Oregon Department of Human Services, State Public Health Division's Committee for the Protection of Human Subjects or is exempt from such review; 7) Any additional safeguards needed to protect the data from inadvertent disclosure due to unique or special characteristics of the proposed research have been required of the researcher.

When quarterly and calendar year data is submitted to the Centers for Disease Control and Prevention National Childhood Lead Poisoning Database, a series of algorithms and programs check the data for valid values and inconsistencies. These algorithms and programs produce reports indicating data errors. A data quality report along with a data file containing any rejected records are transmitted back to the state program for data editing and corrections. The files produced are: Report of the Rejected Records*****.RPT File of Rejected Records*****.BAD Alert Report*****.ALT
Data is entered into STELLAR from a variety of sources. Data is submitted to the CDC on a quarterly and annual (covering previous calendar year) basis.
STELLAR includes names, sex, age, address, blood lead levels and other demographic information. Currently, no online data dictionary is available. For more information see the CDC STELLAR page in the entity and attribute detailed citation.
