Past patients never come back.

1. The "I'll call you" exit

Checkout rebooking works — for the patients who book at checkout. The leak is everyone who says "I'll check my schedule and call you." That sentence is where recall systems quietly hand the entire job to the patient, and patients — busy, well-intentioned, human — mostly don't call. Six months later they're "lapsed," which is a strange word for someone who was never once asked back.

2. Recall is one touch, in one channel

A single postcard. One reminder text from the practice software, sent on the due date, never followed. In a live practice we measure, single attempts at anything — callbacks, follow-ups — behaved like coin flips against busy lives, while persistence changed outcomes completely. Recall is the same physics: the patient who missed your one card in March isn't declining care. They just missed a card.

3. Nobody owns the overdue list

The practice software can print an overdue report; someone has to run it, work it, and log what happened — "when there's time," which in a busy practice is a synonym for rarely. The same measured practice lost a third of its staff-entered inquiries to exactly this mechanism: a next step that was nobody's explicit job. An unowned list isn't a system. It's a report.

4. The long-lapsed are written off entirely

Patients gone two years fall off even the overdue report — mentally archived as lost. The measured data argues otherwise: leads everyone had written off closed at 67% once engaged. The two-year-lapsed patient still has teeth, eyes, and a pet; they're getting care somewhere or neglecting it, and a warm "we'd love to see you again" reaches a person who already knows and trusts your practice. No cold audience converts like that.

The reframe

Recall isn't marketing — it's finishing the care relationship you already started, and it's the cheapest revenue a practice can earn: no ad spend, no stranger-convincing, just systematic asking. The assessment scores whether your asking actually runs.
