Objectives: 1.To describe the conception and model for integrating two programmatically separate information systems; 2. To identify key components of an integrated system and solutions for creating application protocol interfaces (APIs) in a multiple operating system environment. Abstract text: In July, 2000, the New York City Department of Health embarked on designing and developing a master child index (MCI) that will perform registry matching and update functions for the City Immunization Registry (CIR) and Leadquest Registry (LQ). There are over 1.5 million children on each data base with 12 million immunization shots in CIR and 1.8 million lead tests in LQ. Each program currently devotes large resources to de-duplication and data cleaning. A Master Child Index (MCI) will contain demographic information for every child contained in either the CIR or LQ. In addition, a sophisticated matching algorithm called Maximum Entropy De-duplication (MEDD) is expected to reduce human review of ambiguous record pairs by at least 50%. Joint application development (JAD), which involves extensive interaction between users and three vendors has resulted in: 1) creating a glossary MCI fields to link the databases; 2) developing a system of merging duplicates in the MCI; 3) creating MCI operations to accommodate business procedures of the CIR and LQ. The development of the MCI has the potential of identifying children in need of immunizations and for lead poisoning screenings. Integration of these systems will create additional efficiencies and benefit other DOH programs through improved access to data for surveillance, research and community health planning.
