How many calls do clinics miss? What 757 clinic owners and Aeva’s call data show

Aeva AI research. Data: conversations with 757 clinic owners in the year to February 2026, analysed from call transcripts; 37,258 patient calls answered by Aeva in the 30 days to July 2026; customer-reported call logs. Figures last updated July 2026. By Chris Baxter, Co-founder & CEO, Aeva AI.

Most clinics do not know how many calls they miss, because most phone systems do not record it. What the data does show: 78% of the 757 clinic owners Aeva spoke with in the year to February 2026 raised missed calls without being asked, almost all of them had no after-hours or weekend cover, and a typical two-to-three practitioner clinic has about 15 calls a week that would otherwise ring out or reach voicemail. This page sets out those figures and a two-number audit any clinic can run on last month’s phone log.

The figures

• 78% of clinic owners raised missed calls unprompted. Not AI, not marketing, not staffing. What they described was ordinary: a phone ringing mid-consult, a callback that did not happen until the next morning, a front desk stretched too thin. In most cases the patient had moved on before the callback.

• Almost 100% had no after-hours or weekend coverage. Calls went to voicemail or nowhere.

• 55% were doing everything themselves: practitioner, manager and receptionist. They answered calls between consults and returned voicemails at night.

• About 15 calls a week were answered by Aeva for a typical two-to-three practitioner clinic that would otherwise have rung out or hit voicemail (30 days to July 2026).

• 1 in 4 of the calls Aeva answered arrived outside 9 to 5 in the same period.

A staffed desk does not close the gap on its own. Ben runs Essex Coast Physio in Southend with around four practitioners and reception staff already answering the phones. On his first day with Aeva as backup it booked three new patients that would have slipped past the desk anyway

Where the calls go missing

The leak looks different by clinic size. A multi-site group loses calls to volume: peak-hour overflow, every line ringing at once, after-hours calls with nobody on them. The loss is real but spread out, so it is easy to miss. A solo practitioner has the opposite problem: low volume and no backup. Mid-treatment, the phone rings out, and the caller is already dialling the next clinic on Google. In between sit the lunch hour, the note-writing gap and the receptionist who is already on another call.

Why most clinics cannot see it

At a Clinic Mastery session in June 2026, one owner typed a comment that summed up the problem: “Realised that our phone provider doesn’t keep a record of the amount of calls we miss each month.” A clinic would never run a till that did not record what it took. A no-show can be counted. A refund can be counted. The new patient who rang at 7pm, got nothing and booked with the clinic down the road leaves no trace at all. If your provider does not log unanswered calls, you may need one that does; your existing number can usually be moved across.

One Aeva customer did track it, counting every call that did not get through, not only after hours but mid-consult, at lunch and when the desk was busy. Roughly four new patients a week were calling and not reaching anyone, about sixteen a month. Most did not leave a message. At $125 per initial consultation, that was $2,000 a month and $24,000 a year, leaking all day rather than just after 5pm.

The two-number audit

1. Pull one month of phone logs. Count two numbers: total inbound calls, and how many went unanswered. Include after hours, mid-consult, lunch cover and overflow.

2. Assume up to a third of the missed calls would have booked. That is the ceiling Aeva sees in practice: in June 2026 its top-performing clinics were turning more than 30% of otherwise-missed calls into booked patients.

3. Multiply by what a new patient is worth to you, then by twelve. Monthly missed calls × 0.3 × patient value × 12 = annual revenue lost.

For most owners the result is larger than they guessed. It is also the number to weigh any solution against, whether that is more reception hours, an answering service or an AI receptionist.

Closing the gap

Three things reduce missed calls: more hours of cover, a service that takes messages when nobody can answer, or a system that answers and books directly into the diary. Aeva does the last of these. It connects to the clinic’s existing number, answers 24/7 or only when reception cannot, and books, reschedules and cancels in Cliniko, Splose and PracSuite. The clinic sees every call, including the ones that used to leave no trace.

Common questions

Do patients leave voicemails when a clinic does not answer?

Aeva has no measured figure for this. What customers report is consistent: most callers who reach voicemail do not leave a message, and many ring the next clinic instead. The customer who tracked sixteen missed new-patient calls a month found most had left nothing.
