Brief Summary
The purpose of this study is to assess, prospectively, the effect on flu vaccination rates of a pre-visit questionnaire that asks patients to indicate their preferences for a flu shot. Responses to the questionnaire will also be shown to clinicians via additional text in an existing flu shot alert. The investigators hypothesize that the pre-visit questionnaire will lead to increased flu vaccination compared with standard practices.

Outcome Measures
Primary Outcomes (1)
Count of patients with a flu vaccination
Patient received a flu vaccine (yes/no) between the day questionnaires became available for the patient's first scheduled flu-shot-eligible appointment and 7 days following the appointment. Questionnaires were available 14 days prior to the appointment date for appointments scheduled at least 14 days in advance. Questionnaires were available on the day the appointment was scheduled for appointments scheduled less than 14 days in advance. Note that control patients did not receive a flu shot questionnaire, but they may have received other questionnaires from the health system 14 days before their appointment. We will conduct subgroup analyses for people who had responded to MyGeisinger pre-visit messages in the previous year and those who did not.
Up to 21 days
Other Outcomes (7)
Count of patients with a high confidence flu diagnosis
Up to 8 months
Count of patients with a "likely flu" diagnosis
Up to 8 months
Count of patients with flu complications
Up to 8 months
- +4 more other outcomes
Study Arms (2)
Passive Control
NO INTERVENTIONNo change to the standard of care for flu vaccines
Pre-visit Questionnaire
EXPERIMENTALOne-item questionnaire in online patient portal and additional information in the flu shot alert
Interventions
Ask participants to commit to a decision about getting a flu shot
Additional text and icon in the flu shot alert makes the pre-visit questionnaire response salient to the clinician, which could facilitate action or further discussion with the patient
Eligibility Criteria
You may qualify if:
- On a list of active Geisinger patients (all patients on this list attended at least one primary care appointment at Geisinger between 10/1/2008 and 4/13/2022, and either had a Geisinger primary care provider assigned as of April 2022, or were in the Electronic Health Record \[EHR\] since at least September 2021 and had at least one encounter in 2020-2022)
- Has an upcoming flu shot-eligible outpatient visit with a provider
- Has activated Geisinger's patient portal
- Has not yet received a flu vaccine at the time the questionnaire became available, according to the EHR
- Any Geisinger clinician who sees patient-participants in our study for a flu shot-eligible outpatient visit
