In Brief

A clinical study evaluating Portal Reminders for Influenza Vaccination: Direct scheduling link, Portal Reminders for Influenza Vaccination: No direct scheduling link, and 2 other interventions for Influenza and Respiratory Tract Infections. Completed, enrolled 213,773 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. 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)
