Patient Portal - Flu Reminder Recall

November 12, 2021 updated by: Peter G Szilagyi, MD MPH, University of California, Los Angeles

Improving Influenza Vaccination Delivery Across a Health System by the Electronic Health Records Patient Portal

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).

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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:

  1. Standard of care control (no messages)
  2. Up to 1 portal R/R messages
  3. Up to 2 portal R/R messages
  4. 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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

4 months and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers
