Patients in India read WhatsApp. HIMS uses it to confirm appointments, remind before the visit and nudge a review that is due, all from the same appointment and patient record the front desk is already working in.

A reminder is only useful if it comes from the appointment, not from a list somebody keeps separately. HIMS sends appointment confirmations, reminders before the visit and follow-up nudges over WhatsApp using the appointment book and the patient record as the source, so there is no export, no second contact list and nothing to keep in step.
The reason to use WhatsApp rather than a phone call is simply that it gets read and it does not need anyone at the desk to make it happen. The reason to use it rather than a mass broadcast is that each message relates to a real appointment for a real patient under their UHID. Fewer patients drift away after the first visit when the review that is due actually reaches them.
The visit that never happens leaves no trace, which is why most hospitals underestimate it.
Calling every patient before the clinic is somebody's job until the day gets busy, which is every day.
The consultant says come back in six weeks, it is written on a slip, and nothing in the hospital tracks it.
A marketing sheet of phone numbers drifts out of date from the day it is exported.
The clinic runs light and the reason is never recorded anywhere.
Untargeted messages go to everyone, and patients stop reading the ones that matter.
The slot is created against the patient's UHID with their mobile number already on record.
The patient gets the doctor, the date and the time in writing.
A message goes out ahead of the appointment without anyone at the desk acting.
Registration and the token queue pick up from the same appointment.
The doctor sets the follow-up in the record rather than on a slip.
When the review falls due, the patient is reminded on the same number.
Workflow: Every patient booked for the morning list gets a reminder the evening before, with the doctor and the time.
Result: The front desk stops making rounds of calls.
Workflow: The doctor sets the review in the record and the patient is nudged when it falls due.
Result: The follow-up stops depending on the patient's memory.
Workflow: Affected appointments are identified from the roster and patients are told before they travel.
Result: Nobody arrives to a closed room.
Workflow: The patient is told their report is available and opens it from the portal or a shared link.
Result: Fewer trips made only to collect paper.
Follow-up is most of the practice.
Reminders per doctor and department.
Appointments and reports ready.
One less round of calls every evening.
Empty slots that have a reason.
Yes. Messages are sent from your hospital's WhatsApp Business number so the patient recognises who is writing. Setting that up with WhatsApp, including the message templates, is part of the project and is agreed with you before go-live.
Patients who are reminded turn up more reliably than patients who are not, which is the whole reason to do it. We do not publish a figure for it, because the honest answer depends on your specialty, your patients and how far they travel.
From the patient record created at registration under the UHID, so there is no separate contact list to maintain. See UHID registration for how that record is built.
Yes. When the doctor sets a review date in the record, the patient can be nudged when it falls due, which is usually where more visits are lost than at the booked appointment.
Messages come from your own business number, so replies land with your front desk like any other WhatsApp conversation. How you staff that is worth deciding before you switch reminders on.
Related but separate. Imaging reports are shared through AuraPACS as a secure link that needs no login. See WhatsApp medical report sharing for that workflow.
