Most clinics follow up with patients using some mix of three tools: a physical handout (a card or brochure), a text message, or both. Each has real strengths, and none of them solves every part of the problem. Here's a practical, non-promotional comparison.
At a glance
| Criteria | SMS / email | Printed brochure | QR card to a digital experience |
|---|---|---|---|
| Reaches patients with no contact details on file | No | Yes | Yes |
| Content can be personalised per clinic | Partially (mail-merge) | No, fixed at print | Yes |
| Can be updated after handing it out | N/A, one-off message | No, reprint required | Yes, same code |
| Depends on patient consent / opt-in | Yes | No | No |
| Ongoing cost per use | Low, per message | Low, per copy printed | Fixed, included once bought |
| Best moment to use it | After the patient has already engaged, as a nudge | General information, no personalisation needed | The handoff at the end of the consult |
SMS and email
Fast to send, cheap, and familiar. The main weakness is competition for attention: a follow-up text arrives in the same inbox as everything else a patient gets that day, and it's easy to swipe away without opening. It also depends on you having correct contact details and consent to use them, which not every patient at the consult stage will have given yet.
Best for: patients who are already further along and just need a scheduling nudge or a document link.
A printed brochure
Works with zero technology and zero dependency on contact details. The drawback is that it's static: it says the same thing to every patient regardless of what they actually asked about, it can't be updated once printed, and there's no way to know whether it was ever opened again after leaving the clinic.
Best for: general information that doesn't need to be personalised or updated often.
A QR card linked to a digital experience
Combines something physical to hand over, which works for every patient, including ones whose contact details you don't have yet, with content that can be personalised to the clinic and updated without reprinting anything. The tradeoff is that it depends on the patient actually scanning it, and on the destination being genuinely useful once they do. A QR code that opens a generic page isn't meaningfully different from a brochure.
Best for: the handoff moment at the end of a consultation, when a patient is leaving and you have no reliable way to reach them again except through what's in their hand.
How to choose, in practice
- If you don't have the patient's contact details yet, SMS and email are out. You need something physical: a brochure or a card.
- If you want to update or correct the content later without reprinting, a QR card wins. A brochure locks you into whatever it said at print time.
- If the patient has already booked and just needs a reminder, a text message is the lowest-friction option.
- If you want to know whether the material is actually being used, only the QR card gives you that signal (a scan). Brochures and paper leave no trace.
These aren't really competing
In practice, most clinics that follow up well use more than one of these, at different points. A card handed over at the consult reaches every patient at the moment they leave. An SMS reminder later works well for patients who've already engaged and are close to booking. Treating this as a single either/or choice tends to miss the point: the handoff moment and the reminder moment are different problems, and a tool built for one doesn't automatically solve the other.
What actually matters, regardless of the tool
Two things determine whether any of this helps: whether the patient can get back to real, specific information about their own treatment on their own schedule, and whether there's a low-friction path from that information back to booking. A brochure, a text, or a card can each do this well or badly. The format itself doesn't guarantee it.
