Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Standard PCP OutreachBehavioural

    These patients were sent two study outreach messages. Study Outreach 1 was an electronic secure message sent on behalf of the PCP, encouraging COVID-19 vaccination and designed based on behavioral science principles. Letters were sent to patients who had not signed up for the electronic health record portal. 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 OutreachBehavioural

    These patients were sent messages similar to those in Standard PCP Outreach, but with additional culturally tailored content and photos.
