How do I stop recalls reaching patients who already have an appointment booked?
Abtrace includes a double-booking exclusion feature, so you can avoid contacting patients who already have a relevant appointment booked. You set this up when creating an automated recall.
How it works
When building a recall, you can exclude patients who already have an appointment booked by:
- Member of staff — available for both EMIS and SystmOne.
- Slot type — available for EMIS.
SystmOne currently supports exclusion by member of staff only. We're working on adding slot-type exclusion for SystmOne too.
You can also set a time range for the exclusion, so patients are only skipped if their appointment falls within the window you specify — in the last set number of days, or within the next set number of days.

Why use double-booking exclusion
- 🚫 Avoids unnecessary messages — patients who have already booked won't receive a recall asking them to book again.
- 😌 Reduces patient confusion — prevents mixed messages that can prompt duplicate bookings or queries to your reception team.
- 📅 Cuts down on wasted appointments — helps avoid patients booking a second slot they don't need, freeing up capacity for others.
- 🧑💻 Lowers front-desk workload — fewer duplicate bookings and follow-up calls to untangle.
- ⭐ Improves patient experience — patients only hear from you when they actually need to act, keeping your communications relevant and trusted.
