Summary

This project aims to evaluate different approaches to increase COVID-19 vaccine uptake among at-risk patients at Penn Medicine in an equitable and systematic manner through a centralized outreach program. The investigators will evaluate different text-based scheduling and messaging approaches informed by behavioral science to increase uptake among eligible patients, including the use of clinician endorsement, opt-out framing, and scarcity.

Detailed description

This project will evaluate a centralized approach to increasing COVID through direct outreach to eligible patients via text messaging. This pragmatic randomized controlled trial has the following aims: Aim 1: To conduct systematic large scale text message outreach for vaccine delivery among a defined group of Penn Medicine in a way that advances equity. Aim 2: To offer different scheduling workflows through text messaging that might increase uptake and reduce disparities. Aim 3: To compare the equity and efficiency of different messages informed by behavioral science, including PCP endorsement, opt-out framing, and scarcity.

Conditions

• Covid19

Interventions

Type	Name	Description
BEHAVIORAL	Opt-In (Call-Back)	Messaging will include a prompt to agree to scheduling. If patient agrees, the access center will call these patients back to schedule, calling up to 3 times.
BEHAVIORAL	Opt-in (In-Bound)	Messaging will include a prompt to agree to scheduling followed by a prompt to call the Penn Medicine Vaccine Scheduling Hotline to schedule their vaccine appointment.
BEHAVIORAL	Standard Message	The message describes that the patient is eligible for the COVID vaccine.
BEHAVIORAL	Clinician Endorsement	The message will describe an endorsement from the provider to get the vaccination.
BEHAVIORAL	Scarcity	The message will highlight the limited availability and the elevated priority for the patient to receive the vaccine at Penn Medicine.
BEHAVIORAL	Opt-Out Framing	This will highlight that a vaccine is reserved for the patient, implying that they need to opt-out.
BEHAVIORAL	Phone Call	The access center will call these patients to schedule their vaccine appointment. These patients will not receive text messaging.
