Improving Influenza Vaccination Delivery Across a Health System by the Electronic Health Records Patient Portal- RCT #2

University of California, Los Angeles·interventional·Posted Oct 1, 2019·Updated May 5, 2022

In Brief

A clinical study evaluating Portal Reminders for Influenza Vaccination: Gain-framed, Portal Reminders for Influenza Vaccination: Loss-framed, and 1 other intervention for Influenza and Respiratory Tract Infections. Completed, enrolled 430,636 participants across 1 site.

Detailed Summary

This trial is taking place in Los Angeles, CA among patients from primary care practices 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. The investigators will assess the effectiveness of message-framing (gain-framed, loss-framed messages, no messages), as well as the effectiveness of a pre-commitment prompt (pre-commitment prompt, no prompt) asking about a patient's intention to get the influenza vaccination, using a 3 x 2 factorial design.
