When we do schedule appointments, we hope that we can stick to the time. When the patient arrives, we then serve the patient within that allocated time. But as you can imagine, it is often not so straightforward to determine ahead of time how that conversation and the consultation with each particular patient will go. Even if we allocate, say, 15 minutes for what we think is a reasonable consultation time, sometimes the patient that comes in that time slot may have a very complex issue or multiple medical problems that takes a far longer conversation and examination to complete. In which case, it may take half an hour and, therefore, it eats into the next patient's consultation time. In a busy clinic, sometimes, such long conversations, on a particular day, you may have quite a few complicated patients that come in sequentially. That means that there will, therefore, be a snowball effect and patients who are seen at the later part of the session, of the morning session or afternoon session, will therefore end up experiencing a longer waiting time, even though they have been given a scheduled appointment.
