A reminder the day before an appointment is helpful. A promotional message every week is not. The difference is purpose and permission.
Here is how to plan follow-up communication patients welcome.
Start with the purpose
Every message should answer: “Why would this patient want to hear from us now?” Good reasons include:
- Appointment confirmation and reminders.
- Preparation instructions approved by the department, such as fasting before a test.
- Administrative updates, for example a change in OPD timings.
- A feedback request after a visit.
- Health-awareness information the patient has chosen to receive.
If you cannot state the purpose in one sentence, do not send the message.
Get the right permission
- Transactional messages linked to a booking are expected, but say so when you collect the number.
- Promotional or awareness messages need clear, separate consent.
- Record when and how consent was given.
- Make opting out as easy as opting in, and act on it quickly.
Messaging platforms such as WhatsApp Business also have their own policies on opt-in, message types and human escalation.
Tip: Add one line to your booking form: “We will send appointment reminders on WhatsApp. Reply STOP to opt out.” It sets expectations and builds trust.
Protect privacy in every message
- Do not mention diagnoses, test results or treatments in reminders.
- Use neutral wording: “Your appointment is confirmed for Tuesday, 10:30 am.”
- Be careful with shared family phones.
- Store message histories securely and delete them when no longer needed.
Keep a human in the loop
Automation is useful for reminders, but patients reply with questions. Make sure replies reach a named team during working hours, and tell people when they can expect an answer.
Don’t overdo it
Decide a maximum frequency for each type of message. Watch opt-outs and complaints; if they rise, you are sending too much or the wrong things.
Follow-up checklist
- Each message type has a clear, patient-centred purpose.
- Consent recorded, with separate consent for promotional messages.
- Easy opt-out that is honoured quickly.
- No clinical details in reminders.
- Replies reach a named person.
- Frequency limits and a monthly check of opt-outs.
