A no-show is a quiet loss. The slot goes unused, the next person on the waiting list never hears, and the team stands around when it could be busy. A reminder call placed at the right moment is one of the simplest ways to recover those slots. It is also easy to do badly: too early and it is forgotten, too late and nothing can be rearranged, too stiff and it sounds like a recording.
This guide gives you a timing idea, a short script, wording for tricky replies and a practice routine. All names are invented, and details like timing, contact method and what can be said should follow your own organisation's policies.
When to make the call
There is no single best moment, but a sensible window is a day or two before the appointment. That is close enough to be remembered and far enough away that the slot can still be offered to someone else if it is cancelled.
Some teams also send a message first and call only if there is no reply. That is a good pattern when it fits your setting: the message does the routine work and the call handles the people who did not answer. Choose what fits your service, and keep a record of who has been contacted.
What the call must contain
Every reminder call should include these elements, in this order.
- Who you are. "Hello, this is Sam from Hillview Physiotherapy."
- Which appointment. Day, date and time, plus the person they are seeing if relevant.
- Where. The address or entrance if it is not obvious.
- What to bring or do. Only what the patient needs.
- A way to change it. "If you need to move it, just let me know now."
- The cancellation policy, if you have one. State it in one friendly sentence.
Leave out anything unrelated. A reminder is not the moment for new information.
A script you can adapt
You: "Hello, is that Mr Lindgren? It's Sam from Hillview Physiotherapy. I'm calling about your appointment on Wednesday the 20th at 2:30 with Anna. Is that still good for you?"
Customer: "Yes, I'll be there."
You: "Great. We're at 14 Mill Street, the green door next to the pharmacy. Please bring any referral letter you have. If your plans change, call us on 555-0100 and we'll gladly move it. See you Wednesday."
That is it. Roughly thirty seconds, with a clear yes.
Example dialogue: the unsure answer
You: "I'm calling about your appointment on Wednesday at 2:30. Is that still good for you?"
Customer: "Hmm, I'm not sure. I might have a meeting."
You: "Thanks for being honest. I would rather move it than lose the slot. Would Thursday at 3 or Friday at 10 be easier?"
Customer: "Friday at 10."
You: "Friday at 10 it is. I'll send you the new details. Anything else I can help with?"
When the person is unsure, the key move is to offer two alternatives immediately. If you are looking for more on this, see clinic reschedule-first no-show call.
Example dialogue: the cancellation policy
Customer: "I need to cancel."
You: "Understood. Thanks for letting me know in advance. Would you like to rebook for another day now, or shall I leave it for the moment?"
If your service has a cancellation policy, state it simply and neutrally, only where it applies: "Just so you know, our policy asks for 24 hours' notice, so this is fine." Do not use it as a threat. Respect the decision and record the outcome.
Voicemail wording
Keep the voicemail short, polite and discreet. Do not say sensitive details out loud unless your policy allows it.
"Hello, this is Sam from Hillview Physiotherapy with a message for Mr Lindgren about an appointment. Please call us on 555-0100 if you need to change it. Thank you."
Then try again at another time rather than repeatedly in a row, and note each attempt.
Mistakes that raise no-shows
- Calling too late to rearrange. There is no point reminding someone at the last minute.
- Only reading the details. Without a question, you don't know if they'll come. See appointment confirmation call wording.
- Making it sound like a warning. A friendly tone does more than a stern one.
- Not offering a new time. A "no" without an alternative loses the booking.
- Not recording the outcome. The next colleague will repeat the call.
Practise the call so it sounds natural
Reminder calls are short, and they are made many times. That makes them perfect to rehearse. A simple routine:
- Read the six elements aloud twice.
- Role-play three customers: a yes, an unsure and a cancellation.
- Practise the voicemail until you can say it in about fifteen seconds.
- Record yourself and check speed and warmth.
DIRI AI lets you do this by voice. You speak with an AI customer in a prepared situation, for example someone who is not sure they can attend. The AI plays the customer, so you can try the wording, hear a realistic reply and try again. A report on your call follows. The Free plan costs nothing and needs no card: 3 voice calls a month of up to five minutes each, which fits a reminder call well. Try a free practice call, or look at the sample dialogues.
