Abstract

Integrating data that reside in different systems remains an often laborious process, requiring either manual steps or complicated programming. This paper describes a method for state-mandated reporting of childhood blood lead testing results that makes use of object linking and embedding technology and readily available software products to pull together information from different legacy systems. A terminal session emulator employs object linking and embedding automation to extract host data, and Visual Basic routines specify the user interface and database manipulation. This system has significantly increased the efficiency and accuracy with which blood lead testing reports are provided to the local state health department. The system provides a model for a relatively easy solution for laboratories and other groups that need a way to integrate standard data sets that are distributed across legacy systems.
