Database Integration, Immunization Registry, Child Health Registry
BACKGROUND:
In July 2000 a project began to integrate the NYC Citywide Immunization Registry (CIR) and the NYC LeadQuest Registry (LQ) into the new Master Child Index (MCI).
Over 1.5 million children’s records are contained in the CIR and LQ, and approximately 120,000 new records are added yearly through births. The MCI will contain demographic information for every child in either registry and is the initial step in building a comprehensive citywide child health registry.
OBJECTIVE(S):
To describe changes to the CIR due to the implementation of the MCI.
METHOD(S):
Because of MCI development, CIR applications must be modified to use additional demographic data and Lead test data.
RESULT(S):
Modifications are being applied to the CIR’s three front-end applications: 1) PowerBuilder - search and merging screens, 2) Provider Client – provider on-line access, 3) Smart Search – queries for batches of data. Through these modified applications, the CIR will be able to disseminate immunization and lead information to parents and providers, but these changes create programmatic challenges, including the development of protocols for disseminating new information, staff retraining regarding uses of data, and the need for greater collaboration between the CIR and LQ.
CONCLUSIONS(S):
The MCI will facilitate the identification of children in need of both immunizations and lead poisoning screenings, and will benefit other DOH programs through improved access to data for surveillance, research and community health planning. The integration is an efficient way to leverage resources by having the same population in a single integrated database. Although these changes are advantageous, many programmatic challenges must be addressed.
LEARNING OBJECTIVES:
To discuss the impact of integration on an immunization registry program.
