Applying Public Health Informatics to Developing a Training Database System and Investigating an Influenza Outbreak Open Access

Background: Public health informatics (PHI), the science of managing public health information, is a relatively new field that encompasses wide-range of disciplines. The goal of PHI is to find the best way to apply technology to support the work of other public health professionals who use health information and management systems. The following portfolio comprises the planning and design of two information systems proposed to make information available to stakeholders, allowing me to apply my knowledge, skills, and abilities in public health informatics.

Key Aims: The goal of the first project was to plan and design a database system for National Public Health Institutes to increase their ability to efficiently operationalize, manage, monitor and evaluate their training efforts. The goal of the second project was to design an information system that would be used to facilitate the outbreak investigation and surveillance of a hypothetical emerging influenza in low-resource settings.

Methods and Results: A detailed design of the database system was developed by conducting all of the tasks for the early phases of the Database System Development Life Cycle. A high-level design was developed for the influenza information system based on similar systems and leveraging existing technologies.

Conclusion: While much work remains, I was able to both utilize my experience and gain new knowledge by laying the foundation for the establishment of both systems. With thorough, appropriate planning, each system would have a significant impact on public health if developed.
