Electronic nudges to increase influenza vaccination uptake in younger and middle-aged individuals with atrial fibrillation: a prespecified analysis of the NUDGE-FLU-CHRONIC trial.

ABSTRACT:

Aims

Little is known regarding strategies to improve influenza vaccination uptake among individuals with atrial fibrillation (AF). We assessed the effect of electronically delivered behavioural nudges on influenza vaccination uptake and clinical outcomes according to AF status.

Methods and results

This is a prespecified analysis of the nationwide randomized NUDGE-FLU-CHRONIC trial in which citizens aged 18-64 years with a chronic disease were randomized to usual care or six different electronic nudge letters aiming to increase influenza vaccination uptake during the 2023-2024 influenza season. The primary endpoint was receipt of an influenza vaccine on or before 1 January 2024. We reported absolute differences and relative risks (RRs) of each intervention letter vs. usual ca
