Every clinic has a group of patients it no longer thinks about: people who came regularly, then stopped, and nobody noticed because nothing dramatic happened.
They are the cheapest appointments available to you. They already know where you are, they have a record in your system, and they left without complaining — which usually means they did not leave for a reason you would need to fix.
First, find them
Define lapsed precisely, or you will end up messaging everyone.
A working definition: no visit in the last 18 months, and no future appointment booked. Eighteen months rather than twelve, because a patient at 13 months is not lapsed — they are simply late, and a normal recall handles them.
Sort that list by last visit date and by lifetime value. You are looking for people who used to come regularly, not people who came once four years ago.
Decide who not to contact
This matters as much as the list itself. Exclude:
- Patients with an unresolved complaint
- Patients who asked not to be contacted
- Patients you referred elsewhere for ongoing care
- Anyone who has died — check before you send, because sending a cheerful recall to a deceased patient's family is the kind of mistake that gets remembered for years
What to actually say
The instinct is to send a discount. Discounts perform worse than the obvious message, because they read as marketing rather than as care.
What works is short, personal, and mentions the gap without commenting on it:
Hello {name}. It has been a while since your last visit to {clinic} — {month, year}. If you would like a check-up, reply here with a day that suits you and we will find a time.
Three things make this work: it names the clinic, it names the date so the patient does not have to remember, and it makes replying trivially easy.
Do not ask why they stopped coming. It puts them on the defensive and lowers your response rate.
Timing
Send in the first half of the week, mid-morning. Avoid the last week of the month and holiday periods.
Send in batches of thirty to fifty. If you message four hundred people at once and a third respond, you cannot serve them, and the ones you cannot fit in have now been reminded twice that you are inconvenient.
Expect a modest response and plan for it
A reasonable response rate on a well-defined lapsed list is somewhere in the range of one in ten. That is not a poor result — those appointments cost you almost nothing to generate.
Track it: messages sent, replies, appointments booked, appointments attended. That last column is the only one that matters, and it is usually lower than the booked column because reactivated patients no-show more than regulars. Send them a reminder.
Second message, then stop
If there is no reply, one follow-up after three weeks is reasonable. After that, stop.
A patient who ignores two messages has made a decision. Continuing to message converts a neutral former patient into someone who blocks the clinic's number.
Prevent the next cohort
Reactivation treats a symptom. The cause is that nobody noticed the patient stopped coming.
Run the lapsed query monthly instead of annually and the list stays small — and a patient contacted at eighteen months returns far more often than one contacted at four years.
In DOQ, patients with no future appointment and no recent visit can be listed in one view, and recalls send over WhatsApp in the patient's language.
