Summary

This trial aims to create a system that helps patients make better decisions about vaccines and increase the number of people getting vaccinated. The study will test if this system is effective in improving vaccine uptake. This

Who is the study for?
This trial is for individuals who are hesitant or refuse vaccines. It aims to improve vaccine acceptance by using a platform that reminds patients of appointments and provides decision support tools for both patients and providers.
What is being tested?
The study tests an integrated platform with two main features: 'LetsTalkShots', which offers decision support to patients and healthcare providers, and an appointment reminder system, all within the electronic health record (EHR) system.
What are the potential side effects?
Since this trial involves informational interventions rather than medical treatments, traditional physical side effects are not applicable. However, there may be psychological impacts related to changing attitudes towards vaccines.

Trial Design

4Treatment groups
Experimental Treatment
Placebo Group
Group I: Patient-Facing CDS OnlyExperimental Treatment2 Interventions
Among patients without a MYchart account, those with odd birthdates will receive a link to the LTS website (patient-facing CDS) but no integration into the provider workflow.
Group II: Patient- and Provider-Facing CDSExperimental Treatment3 Interventions
Parents of patients with odd birthdates (e.g. April 13) and vaccines due at the index appointment who also have a MYchart account will receive a text message directing the parent to the LTS server with integration into the provider workflow
Group III: Control (MYchart account)Placebo Group1 Intervention
Patients with an even birthdate (e.g. April 14) who have a MYchart account will receive a regular text message and e-mail appointment reminder with a vaccine primer (e.g. "Vaccines are due and reserved for the participant's child"), but no patient- or provider-facing CDS.
Group IV: Control (no MYchart account)Placebo Group1 Intervention
As in the other control group, those without a MYchart account and an even birthdate (e.g. April 14) will receive a text message and e-mail appointment reminder with a vaccine primer but no patient- or provider-facing CDS.
