Yesterday I had an scheduled appointment at Al Khor Hamad Hospital. My scheduled appointment was 9:30am and I arrived early at 8:00am. I went directly to Registration counter but I was advised to come back at 9:00am. Then I realized that they will accommodate you at least 30 minutes prior to the scheduled appointment. So I waited for 1 hour before I got my waiting number. If you have health card you will pay only 30QR and 60QR otherwise. Waiting time is not long enough before you see your doctor, unlike if you have no appointment and you go to Emergency Room, you have to be patient in waiting as there are a lot of patients every day, unless you arrived very early.
