Flu Shot Pre-visit Questionnaire
Study Details
Study Description
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.

Detailed Description
The CDC (Centers for Disease Control and Prevention) recommends a flu vaccination to everyone aged 6+ months, with rare exception; almost anyone can benefit from the vaccine, which can reduce illnesses, missed work, hospitalizations, and death. One barrier to vaccination is a lack of "cues to action," which could be overcome by asking patients for a pre-visit commitment to get a flu shot and additional reminders for the clinician to act on this commitment.
Eligible patients will be randomized to either receive or not receive a one-item, pre-visit questionnaire about the flu shot (that will show responses to clinicians in an existing flu shot alert).
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| No Intervention: Passive Control No change to the standard of care for flu vaccines |
|
| Experimental: Pre-visit Questionnaire One-item questionnaire in online patient portal and additional information in the flu shot alert |
Behavioral: Precommitment Nudge
Ask participants to commit to a decision about getting a flu shot
Behavioral: Salience
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

Outcome Measures
Primary Outcome Measures
- Count of patients with a flu vaccination [Up to 21 days]
Patient received a flu vaccine (yes/no) in the 21 days after pre-visit questionnaires become available for the patient's first scheduled flu-shot-eligible appointment. Questionnaires are available 14 days prior to the appointment date. Note that control patients will not receive a flu shot questionnaire, but they may receive other questionnaires from the health system 14 days before their appointment. The investigators will also conduct subgroup analyses for people who have previously responded to MyGeisinger pre-visit messages in the previous year and those who have not.
Other Outcome Measures
- Count of patients with a high confidence flu diagnosis [Up to 8 months]
Patient received a flu diagnosis via a positive polymerase chain reaction [PCR]/antigen/molecular test (yes/no) during the 2022-23 flu season (from the patient's appointment date through April 30, 2023)
- Count of patients with a "likely flu" diagnosis [Up to 8 months]
Received a "high confidence flu" diagnosis (with positive polymerase chain reaction [PCR]/antigen/molecular test) and/or "likely flu" diagnosis (as assessed via International Classification of Disease [ICD] codes or Tamiflu administration or positive PCR/antigen/molecular test) (yes/no) during the 2022-23 flu season (from the patient's appointment date through April 30, 2023) Note that "likely flu" is a superset of the "high confidence flu" diagnoses
- Count of patients with flu complications [Up to 8 months]
Diagnosed with flu-related complications (yes/no) during the 2022-23 flu season (from the patient's appointment date through April 30, 2023)
- ER visits [Up to 11 months]
Number of ER visits from the patient's message appointment date through July 31, 2023
- Hospitalizations [Up to 11 months]
Number of hospitalizations from the patient's message appointment date through July 31, 2023
- COVID-19 vaccination rates [Up to 8 months]
Received at least one COVID-19 vaccination (yes/no) during the 2022-23 flu season (from the patient's appointment date through April 30, 2023)
- Count of patients with a flu vaccination during the 2022-2023 season [Up to 8 months]
Patient receives a flu vaccine (yes/no) during the 2022-23 flu season (from the patient's appointment date through April 30, 2023)
