How to Send Study Preparation Instructions via WhatsApp: A Guide for Clinics

If you work in a clinic, you know that preparing a patient for a study can be a headache: the patient arrives without fasting, took their medication, or simply didn't understand the instructions. Result: canceled studies, lost appointments, and a front desk full of calls to repeat what was already on a piece of paper.

The problem: instructions that get lost or misinterpreted

Patients receive a printed sheet or a PDF that, let's be honest, almost no one reads completely. Plus, each study has different rules: 8-hour fasting, stopping certain medication, drinking water, etc. When there are doubts, the patient calls, and your staff wastes time repeating the same thing over and over.

The simplest and most effective solution is to use WhatsApp, the app everyone already has, to send preparation instructions clearly, neatly, and consultable whenever the patient needs them.

How to do it step by step (without needing special tools)

1. 1Create a template text for each study: include the name of the study, what it is, preparation (fasting, medication, hydration), what the patient should bring (e.g., comfortable clothing, previous studies), and what time to arrive.
2. 2Save the templates in a document or in your phone's notes, organized by type of study (lab, ultrasound, MRI, etc.).
3. 3When you confirm an appointment, send the text via WhatsApp to the patient. If you use an appointment system, copy and paste the corresponding template.
4. 4Add a line at the end: 'If you have questions, reply to this message.' This way the patient knows they can ask, and you have everything in a single thread.
5. 5If you want to be more organized, use bullet lists or emojis to separate sections (⏰ fasting, 💊 medication, 📄 documents).

How Wando makes it even easier

If your clinic receives many WhatsApp messages, doing everything manually becomes unsustainable. That's where Wando comes in: a tool that uses artificial intelligence to help you respond faster, but without losing control.

• AI suggests responses based on your texts and the answers you've already given before. You approve them with a click and that's it.
• It learns from your real responses, so it suggests better each time, without having to program complicated flows.
• You have a unified message inbox, with templates for preparations and statistics to see which questions are the most frequent.
• It works with Meta's official WhatsApp API, so it's more reliable than connecting a regular number.

In other words: Wando doesn't replace your team, it makes it more efficient. The patient receives the correct preparation, and your staff doesn't waste time writing the same thing twenty times a day.

Common mistakes when sending preparations via WhatsApp

• Sending a long PDF: no one reads it. Better a short message with bullet points.
• Not specifying fasting time in hours (e.g., '8-hour fast' and not 'don't eat anything').
• Forgetting to clarify if the patient can take water or regular medication.
• Not providing a clear consultation channel: the patient doesn't know who to ask and ends up calling the front desk.
• Using the same message for all studies without personalizing: each preparation is different.

Sending study preparations via WhatsApp doesn't have to be chaos. With a little organization and, if you want, a bit of AI help like Wando, you'll reduce cancellations and improve the patient experience.

Three cases that go off the happy path (and what to do)

It's not all about sending the message and done. Sometimes the patient has already arrived for the study and only then writes to you that they didn't understand something, or that they didn't fast. What do you do?

First case: the patient did not fast. Do not scold them or make them feel bad. Check if the test can still be done or if it needs to be rescheduled. If you reschedule, offer the next available appointment and resend the preparation instructions with the new time. That way you don't lose the connection.

Second case: the patient writes to you with a question that is not in the message. For example, whether they can take their blood pressure medication. In that case, no template message will do: you respond yourself, accurately, and if it's a frequent question, add it to the template for next time.

Third case: the patient arrives with previous tests, but in digital format and the doctor needs them on paper. Let them know in advance what format you need. If you didn't clarify it beforehand, have the patient send them to you via WhatsApp and you print them. Simple.

How to measure if management improved

If you don't measure, you don't know if you're improving. The key metrics for a clinic are: cancellation rate, number of calls to the front desk, and time your staff spends answering the same things.

Before implementing any change, write down the current numbers: how many tests are cancelled per week, how many calls you receive per day. After a month with organized WhatsApp messages, compare.

With Wando, you also get message and campaign statistics. You can see which questions are repeated most and adjust your template messages. If the question 'do I need to fast?' appears 50 times, your message isn't being clear.

Another useful metric: response time. If you used to take two hours to reply and now, with AI suggestions, you take five minutes, that shows in patient satisfaction.

What to do when the patient doesn't answer

The patient didn't reply to your confirmation message. It's not the end of the world, but you need to have a plan.

First: don't assume they read it. If the study is important, call them once. If they don't pick up, leave a short voice message: 'We sent you the preparation instructions via WhatsApp, let us know if you received them.'

Second: use the tools you have. With Wando, you can set up automatic replies by schedule: if the patient writes outside of business hours, they receive an automatic message telling them when they'll get a response. That way nobody is left hanging.

Third: if the patient doesn't respond via WhatsApp or phone, don't insist more than twice. That person probably won't come, and it's better to free up the slot for another patient. Mark the appointment as 'unconfirmed' and move on with your list.

How it was done before (and why it failed)

Before, study preparation was communicated in person, when the patient booked the appointment, or with a printed sheet. If the patient didn't pay attention at the front desk, everything was lost.

Paper has a huge problem: it gets lost, wet, forgotten in the car. And if the patient has questions the next day, they have no one to ask until they call back.

Besides, the counter was a bottleneck: the same receptionist who attended in person later answered the phone repeating the same instructions. Each call was an interruption and a waste of time.

That's why WhatsApp changed the rules. It's a channel the patient already has open, where they can reread the message whenever they want, and where they can ask without feeling like they're bothering. It's not magic: it's using the tool that people already use every day.

What NOT to automate in this management process

Automating everything sounds tempting, but there are limits. Not everything can or should be delegated to a machine.

Do not automate medical decisions. If a patient asks whether they can take their medication, or whether they can do the test with a fever, that must be answered by a person with judgment. An AI can suggest, but the final approval is yours.

Do not automate complaint handling. If a patient is angry because their appointment was canceled, an automatic 'thank you for writing to us' message is not enough. That requires a human, empathetic, and quick response.

Also, do not automate rescheduling without control. If a patient asks to change their appointment, a person should do it, because availability, priority, and urgency need to be considered. A bot that changes appointments without supervision can cause a mess.

The general rule: automate the repetitive and predictable, leave the human in human hands. That's what Wando does: it suggests, but you approve.
