Cybernation is the computerized automation of complex system control processes. Cyberspace, a worldwide network of computer environments, provides a new opportunity to conduct and automate public health business practices. Systems control (cybernetics) functions through closed-loop, feedback-controlling information flows. In public health, surveillance systems act as cybernetic information control loops to detect, analyze, and effect (intervene on and prevent) disease. This continuous, real-time monitoring of digital health data streams forms a control loop where public health interventions are monitored and modified - to continuously improve health and eliminate disease. The Wisconsin Health Alert Network integrates these principles into its functional design. Web based design implementation issues include the representation, display and integration of surveillance statistical process control functions (e.g. Shewhart, Cusum techniques) along with epidemiologic science, and informatics (networked information directional flow processes and ergonomic display to maximize practitioner utility). This presentation reviews cybernetic principles along with Wisconsin’s progress toward implementation of its Health Alert Network. As development progressed, a series of survey evaluations and focus groups were held assessing and demonstrating potential network features-with state and local public health practitioners. These ‘feedback’ activities have helped to focus design elements and network functional requirements. Focus group findings are presented along with the essential network features that have emerged from Wisconsin’s Health Alert Network web page design activities.
Learning Objectives: At the conclusion of the session, the participants will be able to (1) list the main principles of cybernetic control systems, (2) articulate key design elements of a successful health alert network system, and (3) describe Wisconsin’s experience in Health Alert Network development
