Primary outcomePrimary: Receipt of the Annual Influenza Vaccine Among Index Patients — 3557; 3518; 3479 Participants
Summary
This trial is taking place in Los Angeles, CA at 21 clinics within the UCLA Health System.
The study design is a 3 arm randomized trial. Patients will be randomized into 1) receiving portal based reminder messages with a video from their PCP encouraging them to receive the influenza vaccine, 2) portal-based reminder messages with an infographic with the image of their PCP encouraging them to receive the influenza vaccine, or 3) the control group. Patients randomized to the intervention arms will receive reminders if they are due for influenza vaccine.
Despite the Advisory Committee on Immunization Practices (ACIP) recommendation in 2010 that all people above 6 months of age should receive an annual flu vaccine, vaccination rates remain low: at 6m-4.9 yrs. (70%), 5-17.9 yrs. (56%), 18-64.9 yrs. (38%), and >65 yrs. (63%). The investigators will assess the effectiveness of MyChart R/R video messages and infographic messages as compared to the standard of care control (Health system messages).
