You are probably spending money on Google ads, or thinking about it, to bring in patients you have never met. Meanwhile, sitting in your practice management system is a list of people who already trust you, already know where you are, and already have the problem you treat. They just stopped booking. That list is almost certainly worth more than your ad budget - and it costs a fraction of the effort to activate.

Why patients lapse (and why it’s not personal)

Most lapsed patients didn’t leave because of a bad experience. Life moved. The pain settled down. They meant to book and forgot. Then enough time passed that ringing felt awkward. A short, warm message that says “we haven’t seen you in a while, here’s a link to book” removes the friction and gives them permission to come back without embarrassment. Thats it. No hard sell required.

Do the maths on your own numbers

Before you decide whether this is worth your time, run this on your own list. You need three numbers:

  • List size - how many patients have not had an appointment in, say, 12 months?
  • Response rate - a recall message to a warm list of people who have already been through your door will outperform cold advertising. You know your patients; use a conservative estimate from your own experience, or start with a small batch and measure.
  • Average appointment value - what does a returning patient typically spend across their next one or two visits?

Multiply the three together: list size × response rate × appointment value. That is the revenue sitting idle in your database. Now compare it to what you spend acquiring a brand-new patient through paid ads - cost per click, click-to-enquiry rate, enquiry-to-booking rate - and you will quickly see why reactivation tends to win on return for effort. A new patient via Google has to find you, trust you, and decide to book, all for the first time. A lapsed patient has already done all of that.

Three honest options

1. Do nothing

Valid if your books are genuinely full and you have a waiting list. If demand already exceeds capacity, reactivation just creates work you cant service. But if you have gaps in the diary most weeks, doing nothing is a choice that costs you the maths you just ran above, every single month.

2. A manual recall afternoon

Export your lapsed list from your practice management system - Cliniko, Jane, or whichever you use - filtered to patients with no appointment in the last 12 months. Write one honest, friendly message. Send it by email or SMS yourself, in batches you can actually respond to. This works. For a list under a few hundred names, a half-day once a month is a reasonable use of time. The downsides are that it depends on someone remembering to do it, it stops when that person is busy or on holiday, and it doesn’t segment by condition, last visit date, or how many times you’ve already tried. But if your list is small and your team is disciplined, dont dismiss this option - it costs nothing but time and it gets results.

3. An automated recall sequence

This is what makes sense when the list is large, the manual approach keeps slipping, or you want the recall to run without anyone remembering to trigger it. A sequence - typically a short series of SMS and email touchpoints, spaced over a few weeks - goes out automatically when a patient crosses your “lapsed” threshold. It stops the moment they book. It can be personalised to the type of treatment they last had. And it runs whether you’re in clinic, on holiday, or dealing with something more urgent.

The important caveat: any automated messaging to patients must sit within your existing consent records and your obligations under UK GDPR. If a patient is on your list and you have a legitimate basis to contact them about their care - which most practices do for existing patients - a recall message is straightforward. If you are unsure about your specific position, your practice’s information governance lead or your professional body is the right place to check. We don’t make compliance claims; we build the system around the rules you confirm apply to you.

The one thing to do today

Export the lapsed list. Just that. Filter your system to patients with no appointment in the last 12 months, export it, and count the rows. Then run the maths above with your own appointment value. You will know in ten minutes whether this is worth pursuing - and if it is, you will have the list ready to act on.

If the number surprises you and you want to talk through whether a manual approach or an automated sequence makes more sense for your practice size, we’re happy to look at it with you. We can map out what a recall sequence would actually involve for your setup - no commitment, just a clear picture of the options. See how we work with clinics here.
