Cancelled appointments and dead time: reminders, short-notice lists and what fills the slot
A cancellation is not the problem. Dead time is: an empty slot nobody knew about until it was too late to fill. Here is how the pieces fit together.
Cancelled is not the same as dead time
A patient who cancels a week ahead costs you less, because you can often offer that slot to someone else. A patient who does not arrive, or cancels an hour before, leaves a hole that is hard to fill. The difference is notice. Much of what you can do about empty slots is about buying notice, or making it cheap to use whatever notice you get. Notice is also unevenly useful. A slot freed up three days ahead can often be refilled from a short-notice list. A slot freed up thirty minutes ahead often cannot, unless the clinician can use the time for notes or letters, or for a patient who is already in the building. Deciding in advance what the clinic does with time it cannot fill, rather than working it out each time, is part of managing dead time.
We use the words clinics use, cancelled and dead time, rather than rates and metrics, because the practical question on the day is simply whether the slot gets used.
Step one: make it easy to confirm or cancel
Patients rarely mean to miss an appointment. They forget, they are ill, or something comes up and cancelling feels awkward. A reminder that lets them confirm or change the booking in one step turns a silent no-show into a cancellation you can act on.
- Send a reminder far enough ahead that a cancellation still leaves time to refill the slot, and a second one close to the appointment.
- Say in plain words how to cancel or change. Make the easy route the one you want people to take.
- Tell new patients your cancellation policy at booking, not at the missed appointment.
- Honour opt-outs. A reminder to someone who asked not to be contacted does more harm than a missed appointment.
In Praxia, appointment reminders by SMS and email are being built and are not yet available to clinics. Patients can set their own communication preferences, and Praxia records their opt-outs. Appointments booked on a clinic’s calendars flow into Praxia as visit records, and cancellations and reschedules sync.
Step two: keep a short-notice list
A short-notice list is a set of patients who have said they would take an earlier or different slot if one opens up. It is the cheapest way to use late notice, because the people on it have already agreed. Done well, it needs three things.
- Consent. Patients opt in to the list, and know how they will be contacted.
- Matching. The slot should go to someone it suits: the right clinician, visit type and time of day.
- A clear deadline. An offer that stays open forever blocks the slot. An offer that expires lets you move to the next person.
Praxia can offer a freed-up slot to patients on a waitlist, and offers expire so the slot is not held indefinitely. This is part of the pilot product, and offers run when a cancellation opens a slot. One of its safety sweeps is off by default.
Step three: look at the pattern, not the incident
One missed appointment tells you little. A pattern tells you something: a particular day, a visit type, a time slot, or a patient whose attendance is slipping. Look at where dead time clusters before you change the policy. Praxia’s reports page gives owners and practice managers measures including bookings per day and no-show rate, filterable by date and clinician. We do not claim that any of this reduces cancellations. It shows you what is happening so you can decide what to change. Check a pattern against how the diary is built before you blame patients. A run of late cancellations on one clinician’s Monday mornings may point to how that session is booked, not to the people booking it.
When a person beats a message
Automation handles the routine. Some patients need a call: someone returning from surgery who has missed twice, or a patient who has gone quiet partway through a plan. Decide in advance who makes that call and when. Praxia’s attrition log shows staff which lapsed patients need a personal call, with the reason recorded, and it is available to management roles. The recall and drop-out guide covers that side.
A simple weekly routine
- Check next week’s schedule for gaps on the day you can still act on them.
- Work the short-notice list for any gap inside the notice window.
- Review last week’s late cancellations and missed appointments once, by pattern.
- Call the patients who need a person, not a message.
Questions clinics ask
Should we charge for late cancellations?
That is a business decision for your clinic, and it depends on your patients and your profession. Whatever you decide, tell patients at booking and apply it consistently. A policy applied unevenly causes more friction than it recovers.
Do reminders work?
Reminders prompt people, and a prompt that is easy to act on helps turn silent misses into usable cancellations. We do not claim a particular reduction, because we have no outcome data and it would vary by clinic.
Who should be on a short-notice list?
Patients who have said they would take an earlier or different slot, and who have agreed to be contacted that way. Keep it small and current. A stale list teaches patients to ignore your messages.
Where Praxia fits, and where this guide stops
Praxia is a pilot with Evolution Medical Care, a clinic run by Praxia’s founders, and is being onboarded to it now. We wrote this guide from how clinics work and from what Praxia is built to do. It is general information, not legal, clinical or financial advice, and nothing here promises a result for your clinic.
