Cardiovascular-Focused Messaging to Improve Influenza Vaccination Rates
In a large individually randomized trial embedded in routine care across a national U.S. health system, a cardiovascular-focused nudge intervention did not increase influenza vaccination rates on a background of low uptake. Nevertheless, this trial illustrates the feasibility of conducting large care-embedded trials of nudges in U.S. health systems. (Funded by Kaiser Permanente's Garfield Memorial Fund; trial registration, ClinicalTrials.gov NCT06571747.).
