# How a Hospital Uses AI for Follow-Up Calls

> How a multi-branch surgical hospital in South India uses AI voice calls to book the follow-up appointments its telecallers kept missing.

**A multi-branch surgical day-care hospital in South India uses an AI voice agent to call patients
after their visit or procedure and book the follow-up appointment the doctor asked for.** Its
telecallers were busy with new enquiries, so follow-ups were the calls that slipped. The agent now
calls in Kannada by default, switches to Tamil, Telugu, Malayalam or English when the patient prefers,
and books directly into the hospital's appointment system. This post describes how it works, without
naming the hospital. It is the [AI receptionist for medical clinics](https://edesy.in/ai-receptionist/use-cases/medical-clinic)
used for outbound follow-ups.

## The problem: follow-ups are the first thing to slip

The hospital runs around ten centres. Each has a small telecalling desk handling new enquiries,
appointment changes and reminders. Follow-up calls after a procedure are important for the patient
and for the hospital, but they never feel urgent, so they get pushed to "later" and often don't
happen. Patients who aren't reminded often don't come back for the review visit the doctor asked for.

## What the AI agent does

1. **Calls the patient** a set number of days after the visit or procedure, in their language.
2. **Checks in** briefly and politely, without giving medical advice.
3. **Offers the follow-up appointment** with the right doctor at the right branch.
4. **Finds free slots** from the hospital's appointment system, books the one the patient picks,
   or reschedules or cancels an existing booking.
5. **Transfers to a person** for any clinical question or complaint.
6. **Saves the outcome**: booked, declined, call back, wrong number, plus an English transcript and
   structured fields for the hospital's records.

## One script per condition

The hospital treats several conditions, and patients speak about each one differently. Instead of
one generic script, there is **one script per condition**, written with the clinical team: what
to ask, which words to use and avoid, and when to hand over to a person. It keeps the call short and
respectful, and avoids the agent improvising on medical topics.

## Connecting to the appointment system

The agent books through the hospital's appointment API using a set of tools:

| Tool | What it does |
|---|---|
| Find location | Nearest or preferred branch |
| Find specialty and doctor | The doctor the patient saw, or another in the same specialty |
| Get free slots | Available times for that doctor |
| Identify patient | Match the caller to their record |
| Book / reschedule / cancel | Change the appointment in the system |

A practical lesson: **set the time zone on every branch**. When one location was missing it, the
agent read out slot times that were off. Small configuration gaps like this show up in the first
days of a pilot, which is why listening to calls early matters.

## Languages

Kannada is the default for most branches, with Tamil, Telugu, Malayalam and English available. The
agent switches when the patient speaks another language. Setting the default per branch, rather than
one language for the whole group, keeps first sentences natural.

## How the pilot is measured

The hospital measures one thing: **follow-up appointments booked**. Not calls made, not minutes.

The comparison that matters to a hospital is not the per-minute price. It is the cost per booked
appointment against the telecaller desk. A telecaller in a South Indian city typically costs
Rs 18,000-25,000 a month and makes a limited number of calls a day alongside everything else. The
AI takes the follow-ups off that desk entirely.

Another lesson: a large share of numbers in any hospital list are wrong, switched off or hang up
instantly. **Pay attention to connected calls and booked appointments, not dialled numbers.** On
Edesy, unanswered calls are not charged.

## Starting small

The pilot started at around 20 calls a day at one set of branches, with the team listening to
recordings daily and adjusting scripts, before increasing volume. For clinics planning the same, our

## Frequently Asked Questions

### How can a hospital use AI calls for patient follow-ups?

The AI calls patients after a visit or procedure, asks how they are, and books the follow-up appointment the doctor asked for, using the hospital's own appointment system to find the doctor, location and a free slot. It frees telecallers from routine follow-ups so they can handle new enquiries.

### Can the AI book directly into the hospital's appointment system?

Yes, if the system has an API. The agent uses tools to look up locations, specialties, doctors and open slots, identify the patient, and book, cancel or reschedule, all during the call.

### Which languages does it support for South Indian hospitals?

Kannada, Tamil, Telugu, Malayalam, Hindi and English, among other Indian languages. A multi-city hospital can set a default language per branch and let the agent switch when the patient prefers another.

### How should a hospital measure an AI calling pilot?

By appointments booked from follow-up calls, not by calls made or minutes used. Compare the cost per booked appointment with what the same bookings cost through the telecaller desk.

### What about sensitive conditions?

Scripts should be written per condition with the clinical team, use respectful language, never give medical advice, and transfer to a person for any clinical question. Tell patients the call is automated and recorded.
