Developing an integrated public health information system for Missouri.

ABSTRACT

The Missouri Department of Health realized it had a problem with 67 different information systems that ran on different platforms and could not communicate with one another. A new, integrated information system, the Missouri Health Strategic Architectures and Information Cooperative (MOHSAIC) is being developed based on information engineering (IE). This article describes IE, the process of developing MOHSAIC, and some key lessons learned in developing the system. Some of the lessons learned include the importance of executive sponsorship, tension between efficiency and program accountability, importance of confidentiality, and difficulties of funding an integrated system. The article stresses how integrated information systems will be important for the viability of public health under health care reform.
