Trial Outcomes & Findings for Patient Portal Flu Vaccine Reminders (5) (NCT NCT05525494)
NCT ID: NCT05525494
Last Updated: 2024-08-07
Results Overview
Percent of patients with annual influenza vaccination (between 9/1/22 - 4/1/23) 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 8/1/22, 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.
