No-show rate is the share of scheduled appointments that go unfilled because the patient or customer never arrives. In primary care it runs 5 to 30 percent depending on the practice. In specialty care, dental, and behavioral health it runs higher. Every no-show is direct revenue loss plus the indirect cost of the slot that could have been given to someone else.
The standard mitigations are reminder calls, reminder SMS, and rescheduling outreach. Each of them helps; none of them scale to a high-touch model with a small front desk. An AI agent that calls every booking the day before, confirms or reschedules, and queues a backfill if the slot opens is doing exactly the work most clinics never get to.
The metric to track is not just the headline no-show rate but the recovery rate, of the no-shows that the AI agent contacted, how many rescheduled, how many filled their slot with a different patient, how many were truly lost. Recovery rate is where the AI earns its keep.
Vorel handles pre-visit confirmations and backfill outreach for clinical and salon use cases, with recovery rate reported alongside the headline no-show number.
