A waiting-room screen is a privacy decision before it is a TV
The screen in the waiting room answers the one question every patient asks: has my number been called? It is also a broadcast to everyone in the room. This guide separates what helps a patient from what exposes them, then covers connecting the screens and running them every day.
Every waiting room asks the same questions: "Has my number been called?" "How many are ahead of me?" Each time one of them lands at the front desk, another patient's check-in stops. A calling screen answers them without anyone raising their voice, which is why it has become a fixture of busy clinics.
But a screen on a wall in a public room broadcasts to everyone in it: other patients, the people with them, sometimes a patient's neighbours. So this guide starts with what should appear on it and what never should, then moves on to connecting and running it. If your problem is the crowding itself rather than the calling, start with the guide to patient flow in a clinic.
What is a calling screen actually for?
Before choosing what to show, decide what the screen has to achieve. There are only three jobs, and anything that serves none of them can go:
- Tell the called patient it is their turn and where to go: the number, and the doctor's name or the room.
- Show the people waiting that the queue is moving: who was called a moment ago, and who is next.
- Cut interruptions at the desk: every question the screen answers is one that never reaches reception.
What the screen should show
| Element | Why | When |
|---|---|---|
| Ticket number | Identifies the patient without revealing who they are | Always |
| Doctor or room | Tells the patient where to go | Always |
| Recent calls | For anyone who looked away at the moment of the call | Always |
| Next in line | Fewer "am I next?" questions | Usually |
| First name or initials | Helps people who forget their number | Clinic's choice |
| Clock and clinic message | Proof the screen is live, and general notices | Optional |
Notice that the number alone is enough for most patients. A name is a comfort for a particular group — older patients and anyone who never looks at their ticket — not something the screen needs in order to work.
What must never appear on it
Whatever is on the screen is announced to the whole room, and it cannot be taken back once someone has read it. Data protection laws in the region treat health information as sensitive, so the safe rule is that the screen shows nothing a patient does not need in order to move. The PDPL compliance checklist for clinics covers what that means for a clinic as data controller.
- Full name: enough for neighbours and colleagues to recognise the patient.
- File or ID number: a permanent identifier of no use to anyone in the room.
- Phone number and date of birth: the raw material of impersonation.
- Reason for the visit or complaint: health information, plainly.
- What the patient owes: a public embarrassment that collects nothing.
- Internal notes: written for staff, not for the room.
The name of the department is health data too
A line like "Noura O. → Fertility clinic" discloses the reason for the visit without naming a diagnosis. In sensitive specialties, show the doctor's name or the room number rather than the specialty.
Numbers only, first names, or initials?
Numbers only is the safest option and suits most clinics. The trouble comes with an older patient, or a relative who never kept the ticket: they hear the chime and cannot tell whether the number is theirs. The common answer is a first name with the family initial — "Mohammed Q." — which is enough for the patient to recognise themselves and not enough for anyone else to.
A full name belongs on a screen in an area only staff enter, such as the corridor where a nurse collects patients. Whichever you choose, tell patients with a sign near reception, and leave out anyone who asks not to be named.
How to connect the screens
Pick the device
Any smart TV with a browser, a tablet, or an old monitor attached to a small PC. Calling needs no special hardware.
Connect it without signing in
A screen should never carry a staff account, because whoever holds the remote has it. The right way is a short code shown on the screen, or a QR scanned from a manager's phone, leaving a key on the device that can be revoked from Settings.
A TV cabled to the reception computer
If the TV is plugged into the reception PC, open the screen in a second window and drag it across. No code, and no internet connection on the TV itself.
Set each screen up on its own
Its branch, whether it shows every doctor or one doctor at their door, the language, a light or dark look, the call chime, and a message along the bottom.
Test it with a real call
Call a number from the reception screen and stand at the furthest seat in the room: can you read it, can you hear it? Fix the font size and the placement before day one.
Keeping it running all day
- Sound: browsers block audio until someone taps the screen or presses a button on the remote once. Make it part of opening up.
- Sleep mode: turn off the TV's power saving, or it will switch itself off mid-session.
- A network drop: a good screen keeps its last picture and shows that it is reconnecting, instead of going blank in front of the room.
- After a power cut: the screen should come back when opened, without being paired again.
- A lost device: a tablet that was stolen or moved should be disconnected in one tap from Settings, and stop showing anything.
The small details that matter
Call again: a patient who missed their number should not be skipped. A button that shows the number again with the chime is faster than looking for them in the room. A screen on the door: in larger clinics, a small screen on each doctor's door showing only their queue cuts traffic in the corridors. Both languages: if some of your patients do not read Arabic, show Arabic and English together rather than alternating. Branches: in a multi-branch clinic, a branch's screen must never show another branch's queue.
How 3yadtk does it
Waiting-room screens in 3yadtk are built on the rules above. You connect as many screens as you like at no extra cost, with an eight-character code or a scanned QR, or with Show on this computer for a TV cabled to reception. A screen shows ticket numbers only by default, and the clinic can choose first names or initials; full names are offered only for screens in staff areas. Data such as the file number, phone number or amount owed never reaches any screen, whatever the settings. Only the owner or a manager can switch screens on or disconnect a device, and every change is in the activity log. The details are on the features page.
