About this study

This randomized controlled trial tested the effect of culturally tailored and standard electronic secure messages and mailings from patients' primary care physicians to encourage COVID-19 vaccination among adults aged 65 and older. Patients who had not received a COVID-19 vaccination or appointment after previous outreach attempts were randomized to receive (a) an electronic secure message and/or mail outreach from their PCP, (b) similar outreach with additional culturally tailored content, or (c) usual care. The primary outcome was receipt of COVID-19 vaccination during the 8 weeks after the initial study outreach date.

Study Outreach 2 was a postcard sent to all patients who had not been vaccinated or made an appointment by four weeks after Study Outreach 1.

Culturally Tailored PCP Outreach
