Behavioral Economics to Improve Flu Vaccination Using EHR Nudges Replication

Patients will be sent text message reminders 3 days and 24 hours prior to their scheduled primary care visit. The messages will inform the patient that a flu shot has been reserved for them at their upcoming visit and encourage the patient to ask their provider about receiving the vaccine.

A default pended order for the flu vaccine will be pended to the patients upcoming primary care encounter and will be visible to the provider during the visit encounter. Clinical staff will have the option of signing the order or dismissing it if they deem it inappropriate for a given patient.

Each month, clinicians will be sent an email containing what percent of their eligible patients received the flu vaccine and how that compares to other peer clinicians in the intervention

High risk patients randomized to receive the high risk intensification nudge will receive a bidirectional text messaging component prior to their visit. This intervention will query the patient about common questions or concerns about receiving the flu vaccine. If the patient responds, it will provide additional educational materials based on the patient's specific concern(s).
