NCT07829432

Brief Summary

The study team will run an A/B test to assess whether pre-appointment messages can reduce appointment no-shows. One message version will indicate the appointment is "reserved" for the patient; another version will be nearly identical but will not include the "reserved" language. A passive control group will not be sent messages.
