Official title
Encouraging Flu Vaccination Among High-Risk Patients Identified by a Rule-Based Additive Risk Index
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
