Summary

"This trial aims to see if personalized text messages can encourage more people to get a flu vaccine compared to generic messages or no messages at all."

Who is the study for?
This trial is for adults over 18 who have a Geisinger primary care provider and haven't had their flu shot for the year according to records. They must also have an upcoming non-urgent, in-person appointment scheduled with enough time to be included in the study.
What is being tested?
The study aims to see if personalized reminders about getting a flu vaccine are more effective than generic reminders or no reminders at all. Participants will receive different types of messages nudging them to get vaccinated.
What are the potential side effects?
Since this trial involves sending reminder messages rather than medical interventions, there are no direct side effects from participating. However, any decision following these nudges, like getting a flu shot, may carry typical vaccination side effects.

Active Control
Group I: Personalized NudgeExperimental Treatment1 Intervention
Patients will receive the nudge predicted to be most effective for them on the basis of the machine learning-derived treatment assignment trees.
Group II: Best NudgeExperimental Treatment1 Intervention
Patients will receive the nudge found to be numerically most effective in the megastudy, including language that a flu vaccine is "reserved" for them at their upcoming appointment.
Group III: Active ControlExperimental Treatment1 Intervention
Patients will receive a simple message encouraging them to get a flu shot at their appointment.
Group IV: Passive ControlActive Control1 Intervention
Patients randomized to this arm will receive no special communications, beyond what Geisinger sends out as standard practice.
