When you call an ambulance, you have to wait for it whereas, if you go immediately, you spend less time. This is my point of view as traffic will always be there. Just bring the patient to Hamad Emergency with the patients' QID and everything else will be taken cared of with professionalism and care. It happened to me before and the caring and support is world class. From the time I arrive until discharge and post operative care. I was so impressed, REALLY.
