Arrival Time Implementation

This is a prospective clinical trial evaluating how behaviorally informed message framing can improve patient on-time arrival for outpatient visits. This trial is being implemented in conjunction with UCLA Health's broader operational quality improvement (QI) efforts to enhance clinic flow and patient experience. The main question it aims to answer is how displaying an explicit arrival time (set to 15 minutes before the scheduled appointment) affects when patients arrive for their appointments, compared to a control condition where only the appointment time is displayed and patients are encouraged to arrive 15 min before the appointment (without an explicit arrival time).
