How to reduce patient no-shows at your clinic: a practical guide

A patient who doesn't turn up isn't just lost revenue. It's a gap in the diary there's no longer time to fill, a practitioner waiting and, quite often, another patient who was given a later appointment because "there was no space".

The good news is that most no-shows aren't bad faith. They're forgetfulness, changes of plan or patients who can't be bothered to call and cancel. And that can be fixed.

First, put a number on the problem

Before changing anything, work out what no-shows cost you. You only need three figures:

• Appointments per week: how many your clinic books in a normal week.
• No-show rate: patients who don't come or cancel so late the slot is lost. If you don't measure it yet, go through the last four weeks of your diary.
• Average revenue per appointment.

An example with round numbers: a clinic with 120 appointments a week, an 8% no-show rate and average revenue of €60 loses around 460 appointments a year (over 48 working weeks). That's more than €27,000 a year.

You can run the numbers with your own figures in our missed appointments calculator.

Why patients don't show up

Knowing the causes helps you choose the fixes:

1. They forget. Especially appointments booked weeks ago: check-ups, cleanings or follow-up sessions.
2. They never find the moment to let you know. Calling during clinic hours is awkward; many keep putting it off until it's too late.
3. Their plans change and rescheduling doesn't look easy.
4. They don't see the value of the appointment, particularly routine check-ups.

Notice that causes 1 and 2 depend almost entirely on how easy you make it for the patient.

What works: a reminder with confirmation

The classic reminder ("this is to remind you of your appointment tomorrow") helps with forgetfulness, but it falls short. What makes the difference is asking for a reply:

• A reminder the day before (or two days before, if your diary fills up at short notice) with two clear options: I'll be there and I can't make it.
• Cancelling has to be as easy as confirming. If cancelling means calling, many patients simply won't come. A patient who cancels a day ahead is doing you a favour: they give you the slot back in time.
• Reception sees who has confirmed. Instead of calling everyone booked for tomorrow, they only call those who haven't replied.

Email, SMS or WhatsApp

The channel matters less than the reply. Email is free and allows buttons, but some patients don't check it every day. WhatsApp has a very high read rate, but sending automatic messages requires the official WhatsApp Business API in the clinic's name. Many clinics combine both: email to confirm the booking and WhatsApp for the reminder.

Whatever the channel, the message should carry only what's essential: date, time and the clinic's name. There's no need to mention the treatment: it's health data and best kept to a minimum.

Make use of the slots that free up

A reminder with easy cancellation means you hear about no-shows earlier. To make the most of it:

• Keep a waiting list of patients who'd like an earlier appointment.
• When someone cancels, offer the slot to that list. Reception can do it by hand, or it can happen automatically.
• Every week, check which days and time slots collect the most cancellations: sometimes the problem is the slot, not the patient.

Other measures that help

• Reinforce the value of the appointment in the booking message: "six-monthly check-up to catch problems early…" works better than just the date.
• Book the next appointment before they leave for treatments with several sessions, but with a reminder: a distant appointment is the one most often forgotten.
• Measure no-shows by practitioner, treatment and time slot. What isn't measured doesn't improve.
• If you have a cancellation policy (for example for long treatments), explain it when booking and mention it in the reminder. Do it tactfully: the goal is for patients to let you know, not to penalise them.

How much can you recover?

It depends on each clinic, and miracle percentages aren't worth trusting. The sensible approach is to measure: record your no-show rate for a month, switch on reminders with confirmation and compare with the following month.

In the calculator you can adjust the improvement assumption to see what it would mean in euros. With the figures from the example above, cutting no-shows by 30% would be worth more than €8,000 a year.

How we do it at Onlitions

We set up reminders with Confirm and Cancel buttons connected to the clinic's diary (Google Calendar or the management software, where it allows it). When a patient cancels, reception gets an alert that a slot is free. After the visit, the patient receives a review request: we explain it in how to get more Google reviews.

If you'd like to see it working, on a 30-minute video call we book a test appointment with your clinic's name and you receive the messages just as your patients would. More about reminders for clinics.
