Developing an integrated public health information system for Missouri

Area of Science:

• Public Health Informatics
• Information Systems Engineering

Background:

• The Missouri Department of Health faced challenges with 67 disparate, non-communicating information systems.
• This fragmentation hindered effective public health management and data sharing.

Purpose of the Study:

• To describe the development of an integrated information system, MOHSAIC, using information engineering (IE).
• To outline key lessons learned during the MOHSAIC development process.
• To emphasize the importance of integrated systems for public health under healthcare reform.

Main Methods:

• Information Engineering (IE) principles were applied to system development.
• The process involved integrating multiple legacy systems into a unified platform.
• Lessons learned were documented throughout the development lifecycle.

Main Results:

• Successful development of the Missouri Health Strategic Architectures and Information Cooperative (MOHSAIC).
• Identified critical factors for integrated system development: executive sponsorship, balancing efficiency and accountability, ensuring confidentiality, and addressing funding challenges.

Conclusions:

• Integrated information systems are crucial for the future of public health, especially within evolving healthcare reform landscapes.
• The MOHSAIC project provides valuable insights into the complexities and requirements for successful public health data system integration.
