The schedule with the best support is a confirmation at booking, a text three business days before the visit, a second text two days before that asks the patient to confirm, and a short reminder on the morning of the visit. GoHighLevel can run it from the Appointment Status and booking triggers. The bottom line: reminders work, an extra early reminder adds a little more, and none of the studies is a dental trial, so measure your own results.
What the studies show
The ADA Health Policy Institute's poll found that late cancellations and no shows were the top barrier to full schedules for 82.7 percent of dentists. A Cochrane review summary quoted in a trial paper judged the evidence that text reminders improve attendance to be of low to moderate quality. A randomized trial at Kaiser Permanente Washington tested a second text three business days before a visit, in addition to the usual text two business days before, for high risk visits: the no show rate fell from 9.1 to 8.4 percent in primary care (relative risk 0.93) and from 20.1 to 17.9 percent in mental health (0.89). An American Journal of Medicine trial of 9,835 patients found no show rates of 13.6 percent with staff reminders, 17.3 percent with automated reminders, and 23.1 percent with none. A randomized comparison in a primary care clinic found text reminders as effective as telephone reminders and more cost effective. A National Health Service trial found that adding the cost of a missed appointment to the text lowered the missed rate from 11.1 to 8.4 percent.
Dental specific figures come from vendors. A Sesame Communications study reported a 22.95 percent reduction in no shows after automated reminders, and a summary of a private orthodontic practice study of 1,193 appointments reports no show rates of 3.49 percent for phone, 2.68 percent for email, and 1.90 percent for text. Treat those as suggestive, since they are not independent.
The schedule
| When | Message | Reason |
|---|---|---|
| At booking | Confirmation with date, time, address, and the cancellation policy | Sets expectations |
| 3 business days before | Reminder with a link to reschedule | The extra early text in the Kaiser trial |
| 2 days before | Reminder asking the patient to reply C to confirm | Gets a response or a cancellation in time to refill the slot |
| Morning of the visit | Short text with the time and address | Catches the forgetful |
| After a no show | One text offering a new time | Recovers the visit |
Keep every text generic: the practice name, the date and time, and a reply option, with no procedure and no tooth. Stating a cost line, as the NHS trial did, is optional and should match the practice's written policy, which our cancellation guide covers.
Build it in GoHighLevel
HighLevel help center pages describe the Appointment Status trigger as firing when an appointment is created or its status changes, with statuses New, Confirmed, Cancelled, Showed Up, No Show, and Invalid, and with filters for calendar, calendar group, tag, user, and who made the change (customer, user, or API). The Update Appointment Status action can set the same statuses from inside a workflow. A third party agency guide adds that Appointment Status is now the main appointment trigger and the older Customer Booked Appointment trigger is being phased out, so use Appointment Status for new builds.
- Build a workflow with the Customer Booked Appointment trigger that sends the confirmation and then Wait steps for each reminder.
- Add an If/Else before each reminder so cancelled and rescheduled visits do not get it.
- Build a workflow with the Appointment Status trigger set to Confirmed that tags the patient Confirmed and removes them from the extra reminders.
- Build a workflow for No Show that sends one reschedule text and a task for the front desk.
- For unconfirmed patients, create a call task for the front desk the day before.
- Compare the no show rate for the month before and after, by new and existing patients.
Worked example
For example, a practice with 500 visits a month and a 10 percent no show rate has 50 no shows (500 times 0.1). If the schedule moves the rate to 9 percent, that is 5 more visits kept (500 times 0.01), and each is a chair hour the practice does not lose.
Mistakes to avoid
- Naming the procedure. Keep texts generic.
- Quoting the vendor figures as promises. Measure your own rate.
- Reminding cancelled visits. Use the If/Else.
- No confirm step. A confirmation gives time to refill a slot.
How this was handled before
Offices called the day before and left a message, or mailed a postcard. Automated calls and texts followed, and trials in medical clinics have since compared channels and timing, though dental specific studies remain mostly from vendors.
What to measure after launch
Track no show rate by new and existing patients, confirmations, cancellations with enough notice, and slots refilled. Compare the month before and after, and keep the schedule only if the rate falls.
Check before you switch it on
US text messages sent from a standard 10 digit number need A2P 10DLC registration. The HighLevel support portal says registration is required for texts to US recipients from 10 digit long code numbers and that toll free numbers do not require it. HighLevel's opt in guidelines also say a person cannot be forced to agree to text messages in order to submit a form, so keep the consent box optional. One compliance guide separates informational texts, which need documented consent, from marketing texts, which need prior express written consent. Ask your attorney which category your reminders fall into. Have your privacy officer approve the reminder text and confirm patient texting consent is documented. This is general information, not legal advice.
Questions people ask
Do text reminders reduce no shows?
Trials show they do, though a Cochrane review summary calls the evidence low to moderate in quality.
Does an extra early reminder help?
In a Kaiser Permanente Washington trial a second text three business days before lowered no shows slightly, with a relative risk of 0.93 in primary care.
Are there dental specific studies?
Mostly vendor studies, such as a 22.95 percent reduction reported by Sesame Communications. Treat them as suggestive.
