Across 105 studies, the average no-show rate came out at about 23%, according to a 2018 systematic review in Health Policy. If your clinic matched that average, a provider with 20 visits booked would lose 4 or 5 of them on a typical day.
Why patients miss visits
The same review looked at which factors were most often linked to missed appointments. The factors that came up most often as significant were a long lead time between booking and the visit, and a history of earlier no-shows.
Younger adults, people with lower socioeconomic status, people who live far from the clinic and patients without private insurance were also more often linked to missed visits.
Most of this is already sitting in your schedule. You know how far ahead each visit was booked and who has missed before.
What a text reminder buys
A 2013 Cochrane review pooled 8 randomized trials with 6,615 participants. Text reminders improved attendance compared with no reminder (risk ratio 1.14).
Attendance was 67.8% with no reminder, 78.6% with text reminders and 80.3% with phone call reminders. Texts and calls performed about the same when compared directly.
In the 2 studies that measured cost, the cost per attended visit was 55% and 65% lower for texts than for calls. The authors rated the evidence low to moderate in quality, so treat the exact numbers as a guide.
The review also found little data on downsides. None of the trials reported in detail on harms such as loss of privacy or failed message delivery, so keep reminder text short and leave clinical details out of it.
More than one reminder helps
A 2016 meta-analysis in BMJ Open combined 21 randomized studies. Patients who got electronic text notifications were 23% more likely to attend (67% vs 54%) and 25% less likely to no-show (15% vs 21%).
For scheduling, the useful part is this: multiple notifications worked significantly better than a single one, and voice reminders appeared more effective than text.
The effect held when the authors accounted for study quality, region and publication year. One caution for US readers: only 1 of the included studies came from the Americas. Most were from Europe, Asia, Africa and Australia.
Call the patients most at risk
Another approach uses a risk score to decide who gets extra outreach. A 2023 review in JAMIA looked at 7 randomized trials and 1 non-randomized study of this approach.
Phone call reminders aimed at patients flagged as high risk reduced no-shows, with a median risk ratio of 0.61 across 3 trials (moderate certainty). In 1 trial, patient navigator calls had a risk ratio of 0.55.
Other ideas fared less well on the evidence. The effect of model-based overbooking was uncertain, and few studies reported on cost, patient acceptability or fairness across groups.
You do not need a predictive model to borrow the idea. A simple flag for prior no-shows and long lead times, the 2 factors the 2018 review found most often, is a reasonable place to start.
A reminder plan to test
The research does not settle the ideal timing. The Cochrane authors asked future studies to report message timing because so few did. That makes your own data the best guide.
- Send at least 2 reminders for visits booked well in advance, since long lead times carry more risk
- Include a confirm link and a reschedule link, so a cancellation becomes an open slot instead of an empty one
- Add a phone call for patients with a prior no-show or a long lead time
- Track no-show rates by visit type and lead time for 8 weeks before and after each change
- Change one thing at a time so you can tell what worked
Watch for patients who stop responding entirely. A reminder cannot fix a visit the patient no longer wants, and a short call may surface a cost, transport or scheduling problem you can solve.
If you use EMR MD, the Insights no-show report shows each rate next to the reminder settings that were active at the time, which makes a before-and-after comparison easier to read.
