This trial is taking place in Los Angeles, CA at clinics within the UCLA Health System.
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 and cost-effectiveness of 1, 2, 3 MyChart R/R messages as compared to the standard of care control (no messages).

Annual epidemics of influenza cause substantial morbidity in the U.S. with up to 40,000 deaths/year and many hospitalizations, emergency and outpatient visits, and significant costs. Concerns about pandemic influenza elevate the need to prevent flu outbreaks.
Numerous studies, including Cochrane or systematic reviews, and reports by the CDC and the Task Force on Community Preventive Services, highlight 4 evidence-based strategies to raise child and adult influenza vaccination rates: 1) increase patient demand by reminder-recall or education, 2) expand patient access to influenza vaccinations (e.g., flu vaccine clinics), 3) implement provider strategies such as prompts or standing orders, and 4) use societal strategies (e.g., reducing costs).
Reminder/recall (R/R), sent by phone, mail or other modality, can improve child and adult influenza vaccination rates. However, fewer than one-fifth of pediatric or adult primary care practices utilize patient R/R. Barriers are lack of finances, personnel, and algorithms to identify eligible patients.
A technological breakthrough that might overcome these barriers involves patient portals-- secure, web-based communication systems, embedded within electronic health records (EHRs), for patients and providers to communicate with each other via email and the internet. Portals are used by about half of Americans and half of UCLA patients. Portals can theoretically improve upon phone, mail or text R/R by adding information such as web links, videos, or images, allowing patients to schedule their own visits, and linking to the medical chart to customize messages.
For this randomized control trial, the intent is to evaluate the impact of patient portal (MyChart) reminder recalls - either 1, 2, or 3 reminders versus the standard of care control group, specifically in relation to raising influenza vaccination rates among UCLA Health System's primary care patients aged 6 months and older.
The proposed design of this 4-arm RCT:
- Standard of care control (no messages)
- Up to 1 portal R/R messages
- Up to 2 portal R/R messages
- Up to 3 portal R/R messages
Hypothesis 1: >1 portal R/R will increase vaccination rates vs. no R/R. Hypothesis 2: More R/R messages will raise vaccination rates (3R/R > 2R/R > 1R/R > 0R/R).
For the primary analysis, only the data from the randomly selected index patients (1 index patient per household) will be included.
For relevant study arms, the first R/R message will be sent in October 2018.

No Intervention: Standard of care control
Participants in this group will not receive any MyChart influenza vaccination reminders
Experimental: 1 MyChart R/R
Participants in this group will receive up to 1 influenza reminder recall notice via their MyChart account
Behavioral: 1 MyChart R/R
Up to 1 flu vaccine reminder recall notice sent via MyChart to patients who are due for the flu vaccine, per the EMR records of the health system.
Experimental: 2 MyChart R/R
Participants in this group will receive up to 2 influenza reminder recall notices via their MyChart account
Behavioral: 2 MyChart R/R
Up to 2 flu vaccine reminder recall notices sent every 3-4 weeks via MyChart to patients who are due for the flu vaccine, per the EMR records of the health system.
Experimental: 3 MyChart R/R
Participants in this group will receive up to 3 influenza reminder recall notices via their MyChart account
Behavioral: 3 MyChart R/R
Up to 3 flu vaccine reminder recall notices sent every 3-4 weeks via MyChart to patients who are due for the flu vaccine, per the EMR records of the health system.
- Receipt of the annual influenza vaccine (between 10/1/18 - 4/2/19) among index patients. Outcomes will be assessed via vaccine data extraction from the electronic health record and external claims and pharmacy data. [ Time Frame: 6 months ]
An index patient will be a randomly selected individual within an included household. The index patient must also be an active UCLA Health MyChart user (>= 1 login over the last 12 months from 8/1/18, excluding activity on the user's initial profile activation date).
Individuals not affiliated with any primary care practice will be excluded from the primary analysis.
- Receipt of annual influenza vaccine (between 10/1/18 - 4/2/19) among all included patients in identified households. Outcomes will be assessed via vaccine data extraction from the electronic health record and external claims and pharmacy data. [ Time Frame: 6 months ]All enrolled study participants, excluding unaffiliated patients and infants < 4 months, will be included in this secondary analysis.
