The short answer
- Indian hospital studies report waits of 1.5 hours and more for a consultation of 6 to 10 minutes.
- The wait is made before the doctor: everyone arriving at opening time, a late start, and slots shorter than the real consultation.
- Note four times for each patient for one week: arrived, called in, consultation over, bill paid. Fix the biggest gap first.
- Give patients a time, not only a token. Size slots to your real consultation time, with a buffer.
- One Indian hospital cut its average OPD wait from 57 to 24.5 minutes by redesigning the patient's path.
How long do patients wait in Indian OPDs?
Studies from Indian hospitals keep finding the same thing: the wait is ten times longer than the consultation, or more.
Medical college hospital, Kolkata (432 patients, 2023)
6.5 min with the doctor
Neurosurgery OPD, PGIMER Chandigarh (103 patients)
10 min with the doctor
058 min115 min
At PGIMER, 45 of those minutes were spent only on the registration line. Private clinics see smaller numbers, but the causes are the same at every size, and so are the fixes.
Where the time goes: one Monday morning, worked out
Take a doctor with 40 patients on a Monday morning and a consultation of about 7 minutes each.
Today
Tokens only, late start
- Tokens open at 9:00, so most patients come by 9:30.
- The doctor starts at 9:20.
- 40 patients × 7 minutes = 4 hours 40 minutes of consultations.
The last patient is seen at about 1:53 pm. The average patient waits over 2 hours.
With the fixes
Times, an on-time start, vitals at the counter
- Each patient gets a time, 7 minutes apart, and comes 10 minutes early.
- The doctor starts at 9:00.
- Vitals are done while patients wait, so the doctor's minutes go to the consultation.
Most patients wait about 10 to 15 minutes. The morning ends at about the same time.
The doctor works the same hours in both mornings. Only the arrivals and the start time changed.
1. Note four times for one week
Without numbers, every talk about waiting is about feelings. For one week, note four times for every patient:
- 1
Arrived
When the patient reaches the counter.
- 2
Called in
When the patient enters the doctor's room.
- 3
Consultation over
When the patient leaves the room.
- 4
Bill paid
When the patient leaves the counter.
A sheet at the counter is enough. Fifty patients show you where the time goes: before the doctor, inside the room, or at the payment and medicine counters. Fix the biggest gap first. An OPD queue management system records these times by itself.
2. Start the OPD on time
A session that starts 20 minutes late makes every patient in it wait 20 minutes longer, and the queue rarely catches up. Research on appointment systems since the 1950s finds that a late start and slots shorter than the real consultation are among the main causes of waiting.
Write the start time on the board and keep it for a month. When ward rounds or surgery run over, tell reception early, so they can tell waiting patients the new time. A known delay is far easier for patients than an unknown one.
3. Give patients a time, not only a token
A token tells a patient their place in line, not when to come. So everyone comes at opening time and waits. A booking with a time spreads arrivals across the morning. Keep some slots open for walk-ins at the hours they usually come, and put both in one queue.
Show the current token on a screen in the waiting area, as Chandigarh's GMCH-32 is doing across its OPDs, so patients stop asking the counter. Send the time with the booking confirmation on WhatsApp, and ask patients to come 10 minutes early, not an hour early.
4. Size slots to your real consultation time
If a new patient takes 12 minutes and the slot is 8, the queue grows by 4 minutes with every new patient. Use your week of numbers: longer slots for new patients, shorter ones for follow-ups.
Leave one or two empty slots in each session for the patient who takes longer or the emergency that cannot wait. Without a buffer, one long consultation delays everyone after it. With one, the queue catches up by itself.
5. Do the work while patients wait
Vitals, weight, the reason for the visit and old reports can all be taken at the counter or in the waiting area. Then the doctor's minutes go to the consultation, and a high BP is flagged before the patient walks in.
Give one trained person a short fixed list: blood pressure, pulse, weight, temperature and, for diabetic patients, the sugar reading. A fixed list keeps this to two or three minutes per patient.
6. Give quick visits their own lane
Showing a report, renewing a prescription or a dressing takes a few minutes, but waits in the same line as a new patient. Short slots at fixed times, or a separate queue, stop these patients from waiting an hour for two minutes.
Many report reviews do not need the patient in the room at all. If the doctor reads the report first and calls back only the patients who need a change, the queue gets shorter for everyone.
7. One payment step, no second queue
In a Faridabad hospital study, patients waited 61 minutes at the medicine counter and 38 minutes at registration, and rated the medicine counter the worst part of their visit. The consultation is not the only queue.
Have the bill ready when the consultation ends, take UPI at the counter, and time the pharmacy line with the same four times.
Does it work? An Indian example
57 → 24.5 min
Average OPD waiting time at a super-speciality hospital in India, before and after a Lean Six Sigma project that mapped every step from registration to the pharmacy and removed the ones that added no value (Gijo and Antony, 2014).
The spread of waits fell too, from about 31 to 9 minutes, so patients could trust the time they were given. No new building and no new doctors: the same people, working in a better order.
Keep the gains: look every Monday
Waiting time creeps back when no one watches it. Every Monday, look at last week's average wait, the five longest waits and the late starts, with reception and the doctors together.
Doccine's OPD queue management system shows the waiting and consultation minutes on every row, makes long waits stand out, flags vitals at the counter, makes the bill at the counter, and has the day's numbers ready at closing time.
Questions people ask
What is a good OPD waiting time?
India has no single national target. Audits often use 30 minutes as a mark: a government audit of hospitals in Jammu and Kashmir (2016–22) counted how many patients waited more than 30 minutes to see a doctor. Measure your own wait first, then set a target your team can keep.
Tokens or appointments: which is better for an OPD?
Both, in one queue. Appointments with a time spread out the patients who plan ahead. Tokens keep walk-ins in order. The doctor should see one list with both.
How is OPD waiting time calculated?
Waiting time is usually the minutes from registration (or arrival) to entering the doctor's room. Note the arrival and called-in times for each patient, subtract, and average over at least a week, because Mondays are often the busiest.
How does an OPD queue management system work?
Reception registers the patient and gives a token or a time. The queue shows each patient's place and how long they have waited, a screen can show the current token, and the doctor calls the next patient from their own screen. Good systems also record the four times, so you can see where the waiting happens.
Does an OPD queue management system reduce waiting time by itself?
No. It records the times, shows who has waited too long and keeps the front desk and the doctor on one list. The wait falls when you act on what it shows, with steps like the seven above.
