The two words that might keep patients from skipping visits
NCT ID NCT07829432
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
Geisinger Clinic is testing whether a pre-appointment message can reduce missed visits. Patients with an upcoming appointment and a higher chance of not showing up receive either a message saying the appointment is 'reserved' for them, a nearly identical message without that wording, or no message. Researchers compare how often patients miss their appointments across the groups.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pre-appointment 'Reserved for you' message sent by text or patient portal
- What this could lead to
- If the wording works, clinics could send a simple, low-cost message that helps more patients keep their appointments.
- What could go wrong
- A single message may not change behavior for people who often miss visits. The effect could be small, and results from one health system may not apply elsewhere.
