NCT04800965 | Completed

• 1 other identifier: IRB#21-000268 (1)
• Study Type: interventional
• Target: 200,000
• Locations: 1 country
• Sites: 1

Brief Summary

This study investigates whether and which type of text-based interventions affect the take-up of the COVID-19 vaccine.

Conditions

Covid19, Vaccines

Keywords

COVID19; Vaccines; Text-messages; Patient Outreach; Behavioral Science

Outcome Measures

Primary Outcomes (1)

• First COVID-19 Vaccine Appointment Scheduled at UCLA Health

  Whether patients schedule their vaccination appointment at UCLA Health within 6 days of receiving the text message (including the day of text message). Specifically, if t=the date of the text message (for the holdout arm, this refers to the date they would have received the text message had they not been assigned to the holdout arm), we will track vaccination appointments made by the end of t+5. While most people just make one appointment, a small percentage update their appointment time. We will have access to the latest few first-dose appointments people schedule by the time of data extraction.

  6 days

Secondary Outcomes (4)

• First COVID-19 Vaccine obtained at UCLA Health

  1 month from text message

• Time of obtaining the first COVID-19 vaccine at UCLA Health

  1 month from text message

• First COVID-19 Vaccine obtained at UCLA Health or any organization reporting to CAIR

  2 months from text message

• Time of obtaining the first COVID-19 at UCLA Health or another location reporting to CAIR

  2 months from text message

Study Arms (5)

Holdout Arm

NO INTERVENTION

In the Holdout arm, patients will not receive text messages about COVID-vaccine.

Simple Text Sub-arm

EXPERIMENTAL

In the Simple Text sub-arm, participants will not receive any additional information.

Behavioral: Patient MyChart Scheduling Link

Simple Text + Video Sub-arm

EXPERIMENTAL

In the Simple Text+Video sub-arm, together with the appointment link, participants will also receive a link to a 2-minute video in the text message. The video contains information about the prevalence of COVID-19 and the effectiveness and safety of the COVID-19 vaccine.

Behavioral: Patient MyChart Scheduling Link; Behavioral: Patient Educational Video

Enhanced Text sub-Arm

EXPERIMENTAL

In the Enhanced Text sub-arm, in addition to the appointment link, the text message will use enhanced language aimed at reducing psychological barriers that prevent patients from scheduling their appointment.

Behavioral: Patient MyChart Scheduling Link; Behavioral: Enhanced Follow through Message

Enhanced Text + Video Sub-arm

EXPERIMENTAL

In the Enhanced Text+Video sub-arm, in addition to the appointment link, the text message will encourage patients to watch a 2-minute video (the same as in the Simple Text+Video sub-arm) and use enhanced language aimed at reducing patients' psychological barriers of following through on scheduling an appointment.

Behavioral: Patient MyChart Scheduling Link; Behavioral: Patient Educational Video; Behavioral: Enhanced Follow through Message

Interventions

Patient MyChart Scheduling Link BEHAVIORAL

Text message includes a link for patients to sign on to their patient portal (Epic MyChart) and schedule their COVID-19 vaccine appointment.

Enhanced Text + Video Sub-arm; Enhanced Text sub-Arm; Simple Text + Video Sub-arm; Simple Text Sub-arm

Patient Educational Video BEHAVIORAL

Text message includes a link to a patient education video that aims to encourage patients to obtain the COVID-19 vaccine.

Enhanced Text + Video Sub-arm; Simple Text + Video Sub-arm

Enhanced Follow through Message BEHAVIORAL

Text message includes information that will use enhanced language aimed at reducing psychological barriers that prevent patients from scheduling their appointment.

Enhanced Text + Video Sub-arm; Enhanced Text sub-Arm
