Patient Retention Strategies Ranked by the Evidence Behind Them
The best-supported patient retention strategies are the plainest ones: remind people before the visit, make the next visit easy to book, and give them a reason to return sooner. Text reminders have the strongest evidence, with a Cochrane review of randomized trials finding about 14% higher attendance than no reminder (risk ratio 1.14, moderate-quality evidence). Continuity with the same clinician, referrals, rewards and memberships have weaker support, so start with reminders and add the rest in order.
This post is about keeping patients and clients coming back to a practice, not retaining participants in clinical trials. It covers med spas, dental and dermatology practices, spas, salons and barbershops.
What is patient retention and how do you measure it?
Patient retention is the share of the patients or clients you served who come back within a period you choose. Before you work on how to get patients to come back, count how many already do. There is no single standard formula for healthcare patient retention, so track a few simple ones monthly:
- Visit-based retention: patients seen at least twice in 12 months, divided by patients seen at least once.
- Rebook-at-checkout rate: visits that end with the next appointment booked, divided by all visits (see med spa rebooking rate).
- Recall compliance: for dental and other recall-based practices, patients due for a recall visit who book one.
- No-show rate: missed appointments divided by booked appointments.
- Member renewal rate: members who renew, divided by members whose billing period ended.
Use your own baseline, not someone else’s benchmark. For context, AmSpa’s 2024 State of the Industry recap reports that an average of 73% of med spa patients are repeat patients, up from 65% in its 2022 report. It is a self-reported survey, and the public recap we read does not say how it defines a repeat patient, so treat it as a reference point, not a target. More in our guide to med spa client retention.
Why do patients stop coming back?
Missed appointments are one place to look. A systematic review of 105 studies found an average no-show rate of about 23%, from 13.2% in Oceania to 43.0% in Africa. The most commonly reported determinants were a long lead time between booking and the visit, and a prior no-show history. It is a global average, so use it as a prompt to measure your own rate, not as a US benchmark.
Cost is another. ADA Health Policy Institute data shows about 45% of the US population visited a dentist in 2022, and in 2023, 13% reported cost barriers to dental care, against 4 to 5% for other health services. The institute notes its MEPS data are a slight underestimate.
Which patient retention strategies have the strongest evidence?
The table runs from strongest evidence to weakest: randomized trials, then reviews of observational studies, then single-site or company-reported findings. Almost none of it comes from aesthetics, so read each row as a reason to test the idea, not a promise.
| Strategy | What the evidence shows | Strength and caveat | Source |
|---|---|---|---|
| 1. Text reminders | Attendance 78.6% with text reminders vs 67.8% with none (risk ratio 1.14) | 8 randomized trials, 6,615 participants, moderate quality; mixed health settings | Gurol-Urganci et al., Cochrane 2013 |
| 2. Book the next visit, keep lead times short | The two most commonly reported determinants of missed visits: long lead time and prior no-show | Review of 105 studies; observational, global average | Dantas et al., Health Policy 2018 |
| 3. Same-clinician continuity | 18 high-quality studies reported significantly lower mortality with more continuity with doctors | Review of 22 observational studies; medical care, association only | Pereira Gray et al., BMJ Open 2018 |
| 4. Referrals | Referred bank customers were about 18% less likely to churn and had about 16% higher six-year value | Observational, about 10,000 customers of one German bank | Schmitt et al., J Marketing 2011 |
| 5. Rewards with a head start | 34% finished a 10-stamp card that began with 2 stamps vs 19% on an 8-stamp blank card | Field experiment, 300 cards, one car wash | Nunes and Dreze, J Consumer Research 2006 |
| 6. Memberships and prepaid passes | A beauty franchise says pass holders have higher retention; about 62% of its 2025 transactions used passes | Company statement in a 10-K; no figure for the gap | European Wax Center 10-K |
How do text reminders reduce missed appointments?
The Cochrane review pooled 8 randomized trials with 6,615 participants. Attendance was 67.8% with no reminder, 78.6% with text reminders and 80.3% with phone-call reminders. Texts performed about the same as calls (risk ratio 0.99), and in two studies cost 55% and 65% less per attendance. The authors caution that the evidence is still insufficient to settle policy and lacks health-outcome data.
What to run this month:
- Text every patient before every appointment, with a one-tap way to confirm or reschedule.
- Get consent first (see med spa text message consent).
- Keep cancellation terms visible (med spa no-show policy).
How do you make the next visit automatic?
The no-show review’s two most common determinants, a long lead time and a prior no-show, shape how you book the next visit:
- Offer the next appointment before the patient leaves. The evidence here is thinner: the review links long lead times to missed visits, not rebooking itself, so watch your no-show rate on far-out bookings and pair them with reminders.
- Give prior no-shows a nearer slot or an extra reminder.
- Keep a waitlist. A waitlist fills the gaps cancellations leave, and online booking makes rebooking one tap.
- Run a recall list. Pull patients who have not returned within a window you set from your own visit intervals, and send a short message with a booking link. Client retention software can build the list. The rules below apply.
Does seeing the same clinician keep patients coming back?
A systematic review in BMJ Open covered 22 observational studies and found 18 high-quality studies reporting statistically significantly lower mortality with more continuity of care with doctors. The authors say all the evidence is observational. It is also medical care, not aesthetics, so it shows association, not proof that continuity keeps patients.
The cheap version: default every rebooking to the patient’s usual provider, show the provider’s name in reminders, and when someone leaves, tell their patients early.
How do referrals and reviews fit into retention?
In Nielsen’s 2021 Trust in Advertising study of more than 40,000 consumers, 88% of global respondents trusted recommendations from people they know more than any other channel. It is global, not healthcare-specific. In one plastic-surgery practice (19,965 patients, 2012 to 2019), patients arrived through medical professionals (34%), other patients (32.7%) and web-based sources (32.5%). That is a single practice, not a US benchmark.
Referred customers may also stay longer. A 3-year study of about 10,000 customers of a German bank found referred customers were about 18% less likely to churn and had about 16% higher six-year value. The authors warn the gap varies by segment, and a bank is not a clinic.
On reviews, ask every patient and reward none for a particular verdict. The FTC’s rule at 16 CFR 465.4 makes it an unfair or deceptive practice to give compensation or incentives conditioned on reviews expressing a particular sentiment. Ask your lawyer how to structure any review incentive. For referral programs, see referral program software and salon referral program.
Do loyalty programs and memberships help patients come back?
Rewards with a head start. In a car-wash field experiment (300 cards), 34% of customers given a 10-stamp card with 2 stamps already applied completed it, against 19% given an 8-stamp blank card needing the same 8 purchases. It is one car wash, so it supports a sign-up bonus, not a size. Ulta Beauty reports in its annual filing that more than 95% of fiscal-2024 sales came from its 44.6 million active loyalty members, which shows most shoppers enroll, not that the program caused sales. A 2025 review of plastic-surgery practice websites found three universal reward systems (Allē, Aspire and Evolus) and four practice-specific programs. See loyalty program software.
Memberships and prepaid plans. European Wax Center’s FY2025 10-K says the share of transactions using Wax Passes grew to about 62% in 2025 and that pass holders and routine guests have meaningfully higher retention rates. That is the company’s own statement, with no figure for the gap. See membership software, med spa membership program and whether med spa packages can expire.
Is keeping a patient really cheaper than finding a new one?
It depends on your practice, and the famous ratios do not hold up well. A widely repeated claim says winning a customer costs a multiple of keeping one, often quoted as 5 to 25 times. Harvard Business Review’s 2014 article that repeats it cites no study for the range. Keiningham and colleagues, in Loyalty Myths, trace the “five times” version to late-1980s TARP research, say its exact origin is hard to determine, and argue the ratio ignores product lifecycle, customer mix and advertising cost allocation.
A second popular claim says a small rise in retention multiplies profit. It traces to Reichheld and Sasser’s 1990 HBR article. One critic, Byron Sharp of the Ehrenberg-Bass Institute, argues it was a thought experiment about a credit-card company, not empirical research.
So skip the borrowed ratios and measure your own cost per new patient and repeat rate (see retention vs acquisition for med spas).
What should you check before messaging patients about retention?
This is not legal advice. These points come from the linked sources, and a lawyer who knows your state should confirm how they apply.
- Text consent. FCC rules at 47 CFR 64.1200 require prior express written consent for advertising or telemarketing calls and texts to wireless numbers made with an autodialer or prerecorded voice, with an exception for health care messages delivered by or for a HIPAA covered entity or business associate. Ask your lawyer whether recall and loyalty texts count as health care messages.
- Whether HIPAA applies to you. 45 CFR 160.103 defines a covered-entity provider as one that transmits health information electronically in connection with a standard transaction, so a cash-only med spa or salon may not be one. HIPAA’s marketing rule requires authorization for marketing uses of protected health information, with exceptions for face-to-face communication and promotional gifts of nominal value. Ask your lawyer about your status and any manufacturer-funded offer (see is your med spa a HIPAA covered entity).
- Patients on Medicare or Medicaid. The OIG’s December 2016 policy statement reads nominal value under the beneficiary-inducement law as no more than $15 per item or $75 in aggregate per patient per year, and not cash or cash equivalents. Ask your lawyer about any reward or discount for these patients.
- Discount advertising. State rules differ. California’s Business and Professions Code 651(c) bars fraudulent, deceitful or misleading price advertising, including bait, discount, premium and gift statements, for healing-arts licensees. Ask your lawyer about your state.
What does a 30-day retention checklist look like?
Work in this order: the early steps have the strongest evidence.
| Days | Action | Done when | Evidence row |
|---|---|---|---|
| 1 to 3 | Pull baselines: no-show rate, visit-based retention, rebook rate, average ticket | Four numbers and a re-measure date | Measurement |
| 1 to 7 | Check text consent; ask your lawyer about HIPAA status and recall texts | Written answer on file | Rules section |
| 4 to 10 | Turn on text reminders with a confirm or reschedule reply | Every appointment gets a reminder | 1. Text reminders |
| 8 to 14 | Offer the next visit at checkout, give prior no-shows a nearer slot, start a waitlist | Rebook and no-show rates tracked weekly | 2. Next visit |
| 11 to 17 | Default rebookings to the usual provider; name the provider in reminders | Same-provider share is visible | 3. Continuity |
| 15 to 21 | Build a recall list of overdue patients; send the first message with a booking link | Replies and bookings counted | 2. Next visit |
| 18 to 24 | Ask every patient for a review; add a referral reward not tied to review sentiment | Both asks part of checkout | 4. Referrals |
| 22 to 27 | Add a sign-up bonus so new members start with progress | Bonus and earn rate written down | 5. Head start |
| 25 to 30 | Draft a membership offer; re-measure baselines | Day 30 compared with day 1 | 6. Memberships |
How do you run this in practice?
Software helps most with the recurring parts. Velarya gives patients an app in your practice’s colors on every plan, or your own app on the Branded and Connected plans. Reminders go out by push notification and email, a waitlist tells patients when a time opens, and patients book in the app, or you switch Velarya booking off and keep your current scheduler. Patients earn points on what they spend at a rate you set, optionally higher for members, plus a sign-up bonus, a birthday gift, QR check-in points with limits and promo codes. Points turn into wallet credit at one fixed rate.
Referrals run on a personal code each patient shares from the app. When a friend joins and meets the rule you set (none, a first paid service, joining a membership, or reaching a spend), both people get points or a complimentary service, set separately. Each friend counts once, with checks against self-referral by account, email and phone.
Memberships bill monthly, quarterly or once a year (yearly is charged up front) and renew automatically. A plan can include a treatment each cycle, wallet credit and member pricing by category or treatment. You can add a 3, 6 or 12-month commitment with an early-cancel fee on monthly and quarterly plans. Members cancel in the app and keep their benefits to the end of the period they paid for, or you can switch that off and have them call. Your front desk can sell a plan by payment link, and payments go to your own Stripe account. Velarya signs a Business Associate Agreement with every practice.
