Rule-Based High-Risk Flu
Conditions: Influenza, Vaccination, Risk Reduction, Health Behavior, Health Promotion
Sex: All
Ages: 18 Years – N/A
Healthy volunteers: No
Phase: NA
Enrollment: 51215
Sponsor: Geisinger Clinic
Location: Geisinger Health Danville Pennsylvania
Summary
Previous work by the study team has shown that informing patients of their high risk of flu and flu-related complications increases their likelihood of getting a flu shot (Rosenbaum et al., 2026). In this work, an artificial intelligence (AI)-based algorithm determined which patients were at high risk for flu. This year, the team will test whether risk messages remain effective when a non-algorithmic rule-based additive risk index (McGovern et al., 2024) is used to identify patients at high risk.
