Behavioral Economics to Improve Flu Vaccination Using EHR Nudges

Many older adults are at risk of illness, hospitalization, and death from vaccine-preventable diseases. More than half of older adults in the United States are not vaccinated for flu which has remained relatively constant over the past decade, and there are racial, ethnic, and socioeconomic disparities in care. In this study, we will evaluate personalized nudges to clinicians and patients to help increase flu vaccination rates during primary care visits among older adults, with a particular focus on population subgroups at high risk for vaccine noncompletion. In a partnership between Penn Medicine and University of Washington (UW) Medicine, this will be a 6-month, multisite, cluster randomized, pragmatic trial with an additional intensification arm for high-risk patients.
