Key points
- In a US national survey of 6,119 adults, people expected to call 1.9 physicians to secure one appointment.1
- A text within minutes, offering a time and a link, keeps the conversation with the clinic that missed the call.
- In 41 UK practices, patient satisfaction tracked appointment availability rather than call handling.2
- wai turns each missed call into a drafted text in that patient's thread, and a person at the clinic approves it before it sends.4
- Five weekly numbers show whether it works, from the share of calls missed to the share of text-backs that become bookings.
Summary
Answer every missed call with a text within minutes, from the clinic's own name, with the earliest suitable time and a booking link. A person approves each text before it sends, and the clinic counts how many missed calls become bookings.
A missed call at 7.42 in the morning can be a booked appointment by 7.50. While the desk checks a patient in, a text sent minutes later with a real time and a link answers the enquiry and the patient books with you.

A missed call is a patient shopping
In a 2021 US national survey of 6,119 adults, respondents expected to call 1.9 physicians to secure an appointment.1 The same study ran a field experiment of 11,016 calls to physician offices, and appointments were offered on 49% of them.1
A text sent minutes after the missed call, with a real time, reaches the patient while they are still choosing.
What the patient remembers is the appointment
Researchers at the University of Exeter rang 41 UK general practices every month from May 2010 to March 2011 as simulated patients asking for a prompt routine appointment.2 Patient satisfaction and willingness to recommend the practice were related to appointment availability rather than to how the call was handled.2
The text-back leads with the appointment. The earliest time with the right clinician, the price and a link to book let the patient say yes in seconds.
The text-back workflow
The call is logged against the caller's number and matched to a patient record if one exists. A text is drafted at once in the clinic's voice, with the earliest suitable slot held. A person at the clinic reads it, edits if needed and approves it. The patient replies or books through the link, and every step lands in the same thread as their emails and WhatsApp messages.
In wai Admin the missed call appears in the inbox with the text-back drafted and the enquiry captured, ready for approval.4 Nothing sends without the team's approval, and every message, draft and approval is written to an event log the clinic can export.5
In a 2020 Accenture survey of US patients, 74% said they were likely to use online chat or texting to give check-in information before an appointment if it was available.3
Three scripts that book
For a new number during opening hours. "Hello, this is [Clinic], sorry we missed your call a moment ago. We can help here by text. Our earliest new patient appointment with [Clinician] is [day, time], [price], and you can book it at [link]. Reply with a question and a member of our team will answer."
For a call from an existing patient. "Hello [Name], this is [Clinic], sorry we missed your call. If it is about your appointment on [day], reply here and we will move it for you, or choose a new time at [link]."
For a call before opening or after closing. "Hello, this is [Clinic]. We are closed and will reply when we open at [time]. You can book any time at [link]. If this is a medical emergency, call [local emergency number]."
Five numbers to measure each week
Track the share of inbound calls missed by hour of day, the minutes from missed call to approved text, the share of text-backs the patient replies to, the share that become a booking within seven days, and the revenue of those bookings. Most phone systems already record the first two.
The hour-by-hour view shows where an extra person on the desk would help and where the text-back covers the gap. The guide to one inbox for every channel covers how calls and texts share a thread.
Where to start
Export last month's call log and count the missed calls by hour. Write the three scripts in the clinic's own voice and agree who approves texts at each time of day. Set a target of every missed call answered by text within ten minutes while the desk is open.
Run it for four weeks and compare missed-call-to-booking against the month before. For overnight calls, pair the text-back with the routing plan in the guide to after-hours enquiries.
Bring a week of your own call log. We show you how each missed call becomes a drafted text, an approval and a booking.
Frequently asked questions
Does the text-back send automatically?
No. wai drafts the text the moment the call is missed, and a person at the clinic approves it before it sends.5 A correct draft takes one tap.
How quickly should a missed call get a text?
Within minutes while the desk is open. Patients often call more than one practice, so the first clinic to offer a time has the advantage.1
What should the text say?
The clinic's name, a short apology, the earliest suitable time with the price, a booking link, and outside opening hours the local emergency number. Keep clinical content out of a text-back.
Is it better to call back than to text?
Do both where the desk has time. The text arrives at once with a time and a link, and a call-back can follow for anyone who does not reply.
What if the caller is not yet a patient?
The call is logged against the number and a new enquiry thread opens. If the person books, the thread becomes part of their record.
Will this replace an answering service?
It changes what an answering service is for. The guide to answering services and AI receptionists sets out where each fits.
