Cut missed appointments by a third with reminders

An empty chair costs a clinic twice: the visit that didn’t happen, and the patient who couldn’t get that slot. Reminders are a small fix with a measured effect. The trial below used text messages; WhatsApp is where many patients in the Kingdom read theirs, though no Saudi trial has measured it yet.

What the trial found

In a randomised trial at an internal medicine clinic in the Eastern Province, 502 patients were split into two groups. Those who got a text-message reminder missed 26.3% of their appointments; those who didn’t missed 39.8% (Youssef, Eastern Mediterranean Health Journal, 2014). That is about a third fewer empty chairs. Every patient asked afterwards wanted to keep getting the reminders.

What it means for your clinic

Your no-show rate may differ from the trial clinic’s; the effect, about a third fewer, is the point. If 1 in 5 of your 40 daily bookings is missed, that is 8 empty chairs. A third fewer brings it to about 5: close to 3 more patients seen a day, or about 13 in a five-day week.

What to send

Keep it short, in Arabic first, use the patient’s first name, and give two easy answers.

نورة، تذكير: موعدك مع د. سارة غدًا الساعة 10:30 في مجمع عيادات مسارات. أرسلي 1 للتأكيد أو 2 لتغيير الموعد.

Noura, a reminder: Dr. Sara, tomorrow at 10:30, at Masarat Polyclinic. Reply 1 to confirm or 2 to change the time.

• The patient’s first name, so a shared phone goes to the right person.
• The doctor’s name, the day, the time, and the clinic’s name and branch.
• Two replies: confirm, or change.

Leave out anything private: no reason for the visit, no test names, no insurer. A phone screen can be read by anyone nearby.

On WhatsApp Business, a message that starts a conversation has to use a template WhatsApp has approved. Write the reminder once, submit it, and wait for the approval before your first send.

When to send it

The day before works for most visits: close enough to remember, far enough to rebook. For early-morning appointments, send it the afternoon before. For procedures that need preparation, send one a few days ahead as well, with what the patient needs to do.

What to do with the replies

A reminder is only half the job. A reply of 2 frees a slot; if nobody sees it, the chair stays empty anyway. The reply should change the appointment on the front desk’s screen, and the freed slot should go back on offer to the next walk-in or the waiting list.

A confirmed visit is also the moment to check cover. The front desk can check tomorrow’s confirmed patients before they arrive, so the claim doesn’t bounce.

Then measure it. Count missed appointments every month, per doctor. The number tells you whether the reminders are working, and which doctors’ patients need a second one.

Measure it properly

A no-show rate is only useful if everyone counts it the same way. Count it per doctor, per month:

• Booked: every appointment still on the schedule the morning of the visit.
• Missed: booked, not cancelled, and the patient never arrived.
• The rate: missed divided by booked.

Leave out appointments cancelled the day before: those slots had a chance to be filled, which is what reminders are for. Compare each month with the month before reminders started, not with another clinic. A doctor whose rate doesn’t move may need a second reminder on the morning of the visit, or a call for first visits.

A no-show policy you can print

Reminders work best beside a clear, kind policy that the front desk can say in one breath. Adapt this one to your clinic.

1. We remind you the day before. Reply 1 to confirm or 2 to change.
2. Can’t make it? Tell us by [time] the day before, and we’ll offer the slot to another patient.
3. A first missed visit is a conversation, not a penalty: we call to rebook.
4. A second missed visit in [three months] means we ask you to confirm by phone before we book again.

نذكّرك قبل موعدك بيوم. إن تعذّر حضورك فأخبرنا قبل [الساعة] في اليوم السابق، لنعرض الموعد على مريض آخر.

Put it at the front desk and on the booking confirmation. The point is not to punish anyone, but to give every slot a second chance.

Questions clinics ask

Do reminders help with walk-ins? No; walk-ins have no booking to remind. They help fill the slots that reminders free up.

Should we send a second reminder? For first visits and early-morning appointments, yes: a short one on the morning of the visit catches patients who confirmed and then forgot. For everyone else, one reminder the day before is enough, and more starts to feel like pressure.

What if the number is a relative’s? Use the patient’s first name in the message, so the right person knows it’s theirs.

Can patients reply in Arabic? Yes, and many will: ١ as well as 1, or a word instead of a number. Whoever reads the replies should accept both.

Do we need the patient’s consent to message them? [Counsel: consent to appointment messages under the Personal Data Protection Law, and how to record it at registration.]
