Abstract: Disclosed herein are systems, methods, and machine readable media for implementing a service for facilitating user engagement and behavior to improve health outcomes. In many populations associated with a shared health insurance plan or Health Maintenance Organization (HMO), members may become less healthy over time, or may remain at a suboptimal state of health. Individual members and the population as a whole may be nudged toward improved health outcomes with various types of interventions. Described herein are embodiments of systems and methods for associating appropriate interventions with populations who are likely to benefit from them, resulting in improved health outcomes for the group.
