Cancellations and no-shows: planning your productivity day around empty slots
Your ceiling for the day, how much to book for your no-show rate, and a plan for an empty 45-minute slot.
To plan your productivity day around cancellations and no-shows, know your ceiling when a slot empties and book for your no-show rate. Decide in advance what an empty slot is for, because your paid minutes stay the same while your billable minutes fall.
This guide is about the day and the week. For the cost over a year and the effective target a no-show rate creates, see how to calculate the cost of a cancellation.
What one bad day does to your productivity
Take an example day. You have 450 paid minutes, an 85% target and nine 45-minute slots booked. The target needs 383 treatment minutes (450 × 0.85 = 382.5, rounded up).
Nine slots are 405 booked minutes, so your ceiling with full attendance is 405 ÷ 450 = 90.0%. Two patients don't turn up and one cancels an hour before. That is three 45-minute slots, or 135 minutes you can't bill.
To see tomorrow’s figure from the slots already booked, follow the steps to calculate productivity from your schedule.
Unless you fill them, your ceiling for the day is now 270 ÷ 450 = 60.0%. You could bill every remaining booked minute and still finish 25 points below target.
The loss comes from attendance and scheduling, and the formula assigns it to you.
Why an empty slot counts against the clinician
Productivity is billable minutes divided by paid minutes. An empty slot lowers the billable minutes and leaves the paid minutes untouched, so the percentage falls. That happens unless your employer changes the formula.
Some employers do change it. These are the approaches in use:
- Excluding documented cancellations from paid time, so the day is measured against the time you had patients available.
- A lower target, set below the full-attendance maximum to allow for the department's no-show rate.
- Overbooking, which moves the risk the other way: when everyone attends, the day runs over.
- A short-notice list, where front desk staff keep a list of patients who can come in at short notice.
The short-notice list is the only one of the four that fills a slot after it empties. The other three change the measurement or move the risk. It also needs front desk time to run.
Planning the day around no-shows
In this guide, the no-show rate counts late cancellations as well as no-shows. It is the share of booked slots that end up empty: empty slots ÷ booked slots × 100. Track it for a month or two before you plan with it. The examples below use 12%, which is an example rate, not a norm.
Expected treatment minutes = booked minutes × (1 − no-show rate)
With nine 45-minute slots and a 12% rate, an average day gives 405 × 0.88 = 356.4 treatment minutes. That is 356.4 ÷ 450 = 79.2%. On an average day this schedule can't reach 85%, even with no cancellations beyond the usual rate.
Minutes to book = minutes needed ÷ (1 − no-show rate)
To expect 383 minutes at a 12% rate, you need 382.5 ÷ 0.88 = 434.7 booked minutes. In 45-minute slots that is ten slots, or 450 minutes. Ten slots fill the whole paid day, so on a day when everyone attends there is no paid time left for notes.
That is the trade-off to put to whoever books your diary, with your own numbers in it. You can check the minutes for any day in the therapist productivity calculator. If your requirement counts sessions rather than minutes, the counselor productivity calculator works out the sessions to book after no-shows.
Does a 15% no-show rate make an 85% target equal to 100%?
Only if every paid minute is booked. On a fully booked 450-minute day, a 15% rate leaves 450 × 0.85 = 382.5 minutes, which is exactly 85.0% of the paid day. You would have to bill every minute that arrived.
A no-show rate is a share of booked slots, and booked time is usually less than paid time. With 405 minutes booked, 15% loses 60.75 minutes, which is 13.5% of the paid day. The average day lands at 344.25 ÷ 450 = 76.5%. The loss in points is smaller than the rate, and the target is still out of reach on an average day with that schedule.
When the bad day is on Monday
A bad day changes what the rest of the week needs. Say Monday ended at 60.0% and your weekly target is 85%, with four equal days left.
The weekly productivity calculator gives (85 × 5 − 60) ÷ 4 = 91.3% on each remaining day, or 411 treatment minutes a day. Nine 45-minute slots are 405 minutes. Even with every remaining patient attending, the week ends at (60 + 4 × 90) ÷ 5 = 84.0%.
So the week needs at least one empty slot filled or one extra slot booked. Knowing that on Monday afternoon gives you four days to find it.
What to do with an empty 45-minute slot
Decide this before it happens. In the moment, documentation is the easy default, and notes written in paid time are a fair use of the slot.
These are the options, roughly in order:
- Fill it with a patient from your own caseload who would benefit from an extra session.
- Do a screening or chart review that would otherwise take time later in the week.
- Write the notes you would otherwise have written unpaid this evening.
All three are legitimate. The pattern to avoid is treating the empty slot as a break and then catching up after hours. Unpaid evening work doesn't show in the schedule's numbers, so it gives whoever runs the schedule no reason to fix the empty slots.
Late cancellations and no-shows need a different fix
A cancellation with two days' notice can be filled from a short-notice list. A cancellation at 8:40am for a 9am appointment usually can't, because nobody can get there in time.
Track the two separately. For each empty slot, record the date, the slot length, and whether it was an advance cancellation, a late cancellation or a no-show. Two months of that gives a rate, and a rate describes the schedule.
Reminders target the late cancellations and no-shows. A 2013 review of randomized trials compared mobile text message reminders with no reminders. Text reminders improved attendance at healthcare appointments, with a risk ratio of 1.14. The review covered text reminders only. For phone calls or a cancellation policy, compare your own tracked rate before and after the change.
If your system has a reason code for non-productive time, use it every time. A report built on codes that nobody enters can't support an argument about the schedule.
When you take the rate to your manager, give it as minutes and points. The yearly hours and the effective-target formula are in the cost of a cancellation.
