Patient Portal Flu Vaccine Reminders (5)

Summary

This trial is taking place in Los Angeles, CA at clinics within the UCLA Health System.

The study design is a 2x2 nested factorial design. Patients will be randomized into 1) receiving text based reminder messages with direct scheduling link, 2) portal-based reminder messages with direct scheduling link, or 3) the control group. Patients randomized to the intervention arms will receive reminders if they are due for influenza vaccine.

Nested within the portal reminder arm, we will have two additional components for which patients will be randomized separately:

1. A pre-commitment prompt, asking patients which time (September, October, November or December) and which place (UCLA, pharmacy, workplace or school, or other) they plan to get their Influenza vaccine with tailored monthly messages based on responses (pre-commitment message with tailored recall messages with direct scheduling vs. standard portal reminders with direct scheduling).
2. A pre-appointment reminder encouraging patients to ask for their influenza vaccine at their upcoming appointment (pre-appointment reminder encouraging influenza vaccination vs. standard pre-appointment reminder not mentioning influenza vaccination)

Nested within the text message reminder arm, we will have one additional component for which patients will be randomized separately:

1\) A pre-appointment reminder encouraging patients to ask for their influenza vaccine at their upcoming appointment (pre-appointment reminder encouraging influenza vaccination vs. standard pre-appointment reminder not mentioning influenza vaccination)

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 messages and text R/R messages as compared to the standard of care control (no messages).

Conditions

• Influenza
• Respiratory Tract Infections

Interventions

BEHAVIORAL

Text Fixed R/R Messages with Direct Appointment Schedule Link

Participants in this arm will receive up to 3 R/R messages by text. R/R message will be sent with a Direct Appointment Scheduling link and instructions to make a flu vaccine appointment.

BEHAVIORAL

Text Pre-Appointment Reminder

Participants will receive a Pre-Appointment Reminder via text when they schedule a visit during the study period.

BEHAVIORAL

Portal Pre-Commitment Prompt with Tailored R/R Messages with Direct Appointment Schedule Link

Participants in this arm will receive a pre-commitment prompt message by portal in September. Tailored R/R messages will be sent monthly by portal based on time and place selected by patients (up to 3). R/R message will be sent with a Direct Appointment Scheduling link and instructions to make a flu vaccine appointment.

BEHAVIORAL

Portal Fixed R/R Messages with Direct Appointment Schedule Link

Participants in this arm will receive up to 3 R/R messages by portal. R/R message will be sent with a Direct Appointment Scheduling link and instructions to make a flu vaccine appointment.

BEHAVIORAL

Portal Pre-Appointment Reminder

Participants will receive a Pre-Appointment Reminder advising them to ask their doctor for the flu vaccine at their upcoming appointment via portal when they schedule a visit during the study period.
