Details and patient eligibility

About

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.

Full 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).
