Industry baseline for outpatient mental-health no-show rate is around 22%. That number has been roughly flat for a decade. The fix isn't 'caring more.' It's the cadence.
What the data says
We A/B tested four reminder cadences across our pilot practices. Same patient demographics, same appointment types, same clinicians. Different reminder mix only.
- No reminder: 26% no-show
- One SMS at T-24h: 18% no-show
- One email at T-24h: 19% no-show
- SMS at T-48h + email at T-4h: 11% no-show
The two-touch cadence cut no-shows by 31% vs. the single SMS — which is what most practices are running today.
Why two touches work
Different reasons trigger different cadence wins.
- T-48h SMS catches conflict-aware reschedules. They have time to actually pick a new slot.
- T-4h email catches the 'forgot' bucket. Just enough lead time to make it.
- Two channels covers the patient who never reads texts AND the patient who never reads email.
The other half: refill the no-show automatically
Cutting no-shows from 22% to 11% is good. Refilling the no-shows you do get is better. We auto-offer the slot to the next 3 patients on the waitlist via SMS the moment a no-show is confirmed. About 38% of those slots get refilled within 30 minutes.
Net effect: actual session-completion rate went from 78% to 95% on the practices that ran both pieces.
What it costs to set up
If you're on Heepsters Practice, both are on by default. If you're on something else, you can usually wire the two-touch cadence in your existing reminder settings — but the waitlist auto-refill almost always requires custom code or a separate tool.
The two-touch alone is worth doing this week. The auto-refill is worth doing this quarter.
