From Denmark: Electronic Nudge for Flu Vaccination Does Not Improve Clinical Outcomes

Electronic letters incorporating cardiovascular (CV) gain framing and repeated messaging, which increase influenza vaccination, do not translate into improvement in clinical outcomes, according to a study published online March 19 in the Annals of Internal Medicine.

Niklas Dyrby Johansen, M.D., from Copenhagen University Hospital-Herlev and Gentofte in Denmark, and colleagues examined the effects of the successful nudging interventions seen with the Nationwide Utilization of Danish Government Electronic letter system for increasing inFLUenza vaccine uptake (NUDGE-FLU) trial on downstream clinical outcomes in the 2022 to 2023 influenza season. Data were included for 964,870 Danish citizens aged 65 years or older who received usual care or nine different electronically delivered behavioral nudging letters; the analysis set included 691,820 participants.
