Improving Influenza Vaccination Delivery Across a Health System by the Electronic Health Records Patient Portal RCT 5
In Brief
A clinical study evaluating Text Fixed R/R Messages with Direct Appointment Schedule Link, Text Pre-Appointment Reminder, and 3 other interventions for Influenza and Respiratory Tract Infections. Completed, enrolled 262,085 participants across 1 site.
Detailed 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).

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