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.
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.
