Walk-ins vs appointments in a small clinic. How to run both in one queue and keep it fair.
An Indian OPD cannot refuse walk-ins and cannot ignore bookings. The answer is not to choose but to run one queue with a clear rule for what a booking is worth. This post is that rule, the words to say to each kind of patient, and the handful of cases that cause arguments.

- One queue. A booking buys a place in the order and an arrival window; it does not buy a clock time or a right to go in on arrival.
- Walk-ins get the next place. Nobody is told "we are full" unless the doctor has set a cap for the session.
- Lateness has one rule, stated on the booking and at the desk: hold the place for a fixed grace period, then join where the queue stands.
- Tell patients the position, not the minutes. When the doctor runs behind, say so once, to the room.
A small clinic runs walk-ins and appointments by putting both in one queue, in which a booking earns a reserved place in the order and an arrival window, and a walk-in takes the next free place on arrival. Neither gets a promised clock time. A booked patient who arrives inside the window goes in at their place; one who arrives after the grace period joins where the queue stands. The rule is printed on the booking message and said at the desk, and it is the same for everyone.
Why not go appointment-only, or walk-in-only?
Because neither matches how patients in a tier-2 or tier-3 city actually come. A clinic that turns away walk-ins loses the patient who came because they were unwell today, which is most of them, and the regulation on obligations to the sick (regulation 2.1.1 of the 2002 ethics regulations) says a physician must treat in an emergency and must not arbitrarily refuse treatment. A clinic that takes no bookings makes every patient wait in the room, which is fine for a small morning and unbearable for a crowded evening. The post on appointment booking for walk-in clinics covers why most clinics end up with both; this post is about running the mix.
What does a booking actually earn a patient?
| Booked patient | Walk-in | |
|---|---|---|
| Place in the order | Reserved when the booking is made, held through the grace period | The next place at the moment of arrival |
| Time | An arrival window ("5 to 5:30 baje aaiye"), not a slot | A rough wait stated as patients ahead |
| If late | Past the grace period, joins where the queue stands | Not applicable; a walk-in who steps out keeps the place if the desk is told |
| If the doctor runs late | Told the new estimate, keeps the place | Same |
| Fee | Same fee; a booking does not change the rate | Same |
The row that prevents most arguments is the first. A booking is a place, not a priority. A walk-in who arrived at 4:50 and a booked patient whose window is 5 to 5:30 are both in the order; the booked patient's place was fixed earlier, which is why they go in before the 4:50 walk-in even though they arrived later. Said plainly at the desk, this is accepted. Left unsaid, it looks like queue-jumping.
How many bookings should a session take?
Fewer than the doctor can see. If every place is booked, the first walk-in of the day has nowhere to go and the clinic has become appointment-only by accident. At most small clinics the workable split is to book a part of the session and keep the rest open, with the proportion set by the doctor from how the last few weeks actually ran. There is no right percentage; there is only the doctor's pace and the clinic's walk-in pattern, and both are in the register or the day's report. Revisit the split monthly.
What do you tell each patient?
At booking
The arrival window, the grace period, and that the clinic sees walk-ins too, so there may be a short wait. Put all three on the booking message. A patient who read "5 to 5:30, thoda wait ho sakta hai" does not argue at 5:20.
To a walk-in
The number of patients ahead, a rough time, and that some of the places ahead are bookings. "Aapse pehle saat log hain, do booking wale bhi hain, lagbhag chaalis minute." If the clinic sends tokens to the phone, say they can wait outside and watch for the message.
When the doctor runs behind
Once, to the whole room, with a new estimate. Not patient by patient as they ask. Then update the bookings that have not arrived yet with one message each, so they do not sit in the room for an hour.
The cases that cause arguments, and the rule for each
- Booked patient arrives early. They wait for their place, like anyone; arriving early does not move the place forward.
- Booked patient arrives after the grace period. They join where the queue stands. Say it kindly and say it the same way every time.
- Walk-in insists they are an emergency. The desk does not judge it; inform the doctor at once and let the doctor decide. See an emergency patient at the OPD.
- Booked patient brings a second family member to be seen. The second person is a walk-in and takes the next place.
- No-show. The place is released after the grace period; nobody is moved to fill it, the queue simply closes up. Patterns that cut no-shows are in reducing patient no-shows.
- Two bookings for the same window from two channels (phone and WhatsApp). Only one list may exist. Every channel writes to the same register or system, and the desk checks it before confirming.

Questions
Should booked patients pay a different fee?
No. A booking is a place in the order, not a service. Charging more for it turns the queue into something patients pay to skip, and the room sees it.
What grace period should a clinic set?
Whatever the doctor will enforce every time. A short, stated period applied without exceptions beats a generous one that is argued about. Put it on the booking message.
Can a clinic refuse a walk-in because the session is full?
A clinic can set a cap for the session and say so at the door, but the 2002 ethics regulations (regulation 2.1.1) require a physician to treat in an emergency and not to refuse treatment arbitrarily. A walk-in who may be an emergency is shown to the doctor, cap or no cap.
