Brief Summary:
In randomized clinical trials and observational studies influenza vaccination has been shown to be effective in reducing influenza-related illness hospitalizations cardiovascular events and mortality in select populations However the real-world effectiveness of influenza vaccination is limited by its uptake This study will investigate whether digital behavioral nudges delivered via the official mandatory Danish electronic letter system can increase influenza vaccine uptake among adults aged 18-64 years with chronic diseases
Detailed Description:
The study is a prospective randomized open-label implementation trial The study population will consist of persons aged 18-64 years identified as eligible for free-of-charge influenza vaccination due to a chronic condition Subjects will be identified through Danish nationwide health registries using codes from the International Classification of Diseases 10th revision ICD-10 Individuals will be randomized to 1 of 7 arms 1 usual care arm and 6 intervention arms with each testing different nudging strategies employing various behavioural economic principles The interventions will be delivered through the official mandatory Danish electronic letter system All subject data will be retrieved from the Danish nationwide registries with the exception of information on intervention allocation Endpoints will be retrieved at prespecified dates using prespecified search algorithms
