COVID-19 Vaccine Text Outreach

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.

Conditions

• Covid19

Interventions

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.
