Article Synopsis
  • The study aimed to compare the effectiveness of electronic health record (EHR)-based portal reminders and text message reminders in increasing influenza vaccination rates in a health system.
  • Conducted as a randomized clinical trial from September 2022 to April 2023 at UCLA, the trial included over 262,000 patients across different reminder strategies.
  • Results showed differences in vaccination rates based on the type of reminder sent, indicating that tailored reminders could enhance public health efforts to improve flu vaccination participation.

Influenza vaccination rates are low. Working with a large US health system, we evaluated three health system-wide interventions using the electronic health record's patient portal to improve influenza vaccination rates. We performed a two-arm RCT with a nested factorial design within the treatment arm, randomizing patients to usual-care control (no portal interventions) or to one or more portal interventions.

Background: Adult influenza vaccination rates are low. Tailored patient reminders might raise rates.

Objective: Evaluate impact of a health system's patient portal reminders: (1) tailored to patient characteristics and (2) incorporating behavioral science strategies, on influenza vaccination rates among adults.

Enhancing vaccine uptake is a critical public health challenge. Overcoming vaccine hesitancy and failure to follow through on vaccination intentions requires effective communication strategies. Here we present two sequential randomized controlled trials to test the effect of behavioural interventions on the uptake of COVID-19 vaccines.

Objectives: In a large health system, we evaluated the effectiveness of electronic health record patient portal reminders in increasing pediatric influenza vaccination rates.

Methods: We conducted an intention-to-treat randomized clinical trial of 22 046 children from 6 months to <18 years of age in 53 primary care practices. Patients (or parent and/or proxies) who were active portal users were randomly assigned to receive reminder messages framed as gains or losses or no messages.

Importance: Influenza vaccination rates across the US are low. Because few practices send patient reminders for influenza vaccination, a scalable patient reminder system is needed.

Objective: To evaluate the effect of patient reminders sent via a health care system's electronic health record patient portal on influenza vaccination rates.

Objective: The study sought to assess, for children in one large health system, (1) characteristics of active users of the patient portal (≥1 use in prior 12 months), (2) portal use by adolescents, and (3) variations in pediatric patient portal use.

Materials And Methods: We analyzed data from the electronic health record regarding pediatric portal use during 2017-2018 across a health system (39 871 pediatric patients).

Results: Altogether, 63.
