Patient Portal Reminder/Recall for Influenza Vaccination in a Health System- UCLA Portal R/R Influenza RCT 3

Not Applicable

Completed

• Conditions: Influenza; Respiratory Tract Infections
• Interventions: Behavioral: Pre-Commitment Prompt; Behavioral: Pre-Appointment flu vaccine reminders

• Registration Number: NCT04533685
• Lead Sponsor: University of California, Los Angeles

Brief Summary

This trial is taking place in Los Angeles, CA among patients from primary care practices within the UCLA Health System.

The study design is a 2x2x2 factorial design, nested in a parallel 2-arm trial. The parallel arms are control v. reminder letter (reminder messages sent via the patient portal, reminding participants of an overdue influenza vaccine)

Nested within the reminder letter arm, we will have 3 additional components:

* A direct scheduling link within the reminder letter enabling the patient to schedule an influenza vaccine only visit (direct scheduling link vs. no direct scheduling link).

* A pre-commitment prompt (pre-commitment prompt vs. no prompt) asking about a patient's intention to get the influenza vaccination

* 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)

Detailed Description

This trial is taking place in Los Angeles, CA among patients from primary care practices within the UCLA Health System, using 2x2x2 factorial design, nested in a parallel 2-arm trial.

Sub-optimal vaccination rates are a significant problem in the U.S., despite their effectiveness in preventing morbidity and mortality from vaccine-preventable illness. For influenza specifically, annual epidemics of influenza cause substantial morbidity in the U.S. with up to 40,00-80,000 deaths/year and many hospitalizations, emergency and outpatient visits, and significant costs.

Reminder/recall (R/R) messages, sent by phone, mail or other modality, can improve child and adult influenza vaccination rates. However, the majority of pediatric or adult primary care practices to not conduct 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.

This randomized controlled trial will assess the effectiveness of reminders messages, encouraging influenza vaccination, sent to patient portal users on increasing influenza vaccination rates within a health system by randomizing patients to two groups: 1) two-thirds of patients will receive reminder letters, 2) one-third will not receive reminders.

Patients in the reminder arm will be further randomized (separately) for three additional components: 1) direct appointment scheduling, 2) pre-commitment prompts and 3) pre-appointment reminders.

Direct scheduling: The convenience of scheduling an appointment for influenza vaccination may increase the likelihood that patients receive an influenza vaccination. Patients receiving reminders will be randomized to receive one of two types of reminder letters: 1) one half will receive flu vaccine reminder letters with a link to the MyChart direct appointment scheduling page and 2) one half will receive flu vaccine reminder message without the direct appointment scheduling link.

Pre-commitment: Another potential influence on the decision to vaccinate is pre-commitment. Previous studies suggest that, upon being prompted, indicating an intention to do something increases the likelihood of following through. Patients will be randomized to one of two groups: 1) one half will receive pre-commitment prompt at the beginning of influenza vaccination season and 2) one half will not receive a pre-commitment prompt. The pre-commitment prompt asks whether the patient intends to receive influenza vaccine, and where and when they plan to get the vaccine.

Pre-appointment flu reminders: Finally, a missed opportunities for vaccination occurs when patients are eligible for vaccination but are not offered a vaccine at their medical appointment. Pre-appointment reminders, sent in advance of an upcoming appointment, encouraging the patient talk to their doctor about influenza vaccination, may increase the likelihood of that patient receiving a vaccine. Patients will be randomized to one of two groups: 1) one half will receive modified pre-appointment reminders that mention influenza vaccination and 2) one half will receive the standard pre-appointment reminders for an upcoming appointment (no mention of influenza vaccination).

Primary Outcome Measures

Name	Time	Method
Number of Index Patients Who Received Annual Influenza Vaccine	6 months	Receipt of the annual influenza vaccination (between 8/1/20 - 4/1/21) among index patients. Outcomes will be assessed via vaccine data extraction from the electronic health record and external claims and pharmacy data.; The index patients must also be an active UCLA Health MyChart user (\>= 1 login over the last 12 months from 8/1/20, 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.
