My experience with the Devlet:
Just inside the main door on the left hand side is the "tourism office". I arrived at 9am as this is when the staff open up & transfer from the A&E where they are overnight. Register with your name, address etc. & you must have your residency card, kimlik number & your passport. I forgot my passport (didn't actually think I'd need it as I had a kimlik) & was allowed to visit the doc but that was more by luck than judgement I think!
The staff will then take you to the appt desk & make an appt (you jump to the front of the queue with them!) with the specialist of your choice. There is no GP doctor, you have to choose which type of doc you need to see, I wanted the Cardio doc.
Back to the main entrance where you pay (with a kimlik it's currrently 15.5tl), without a kimlik I believe it's substantially more. The tourism helper then takes you to the waiting area for your specified doctor, you have a number which is traceable on a digital board so can see where you are in the queue at anytime. After you have seen the doc (in my case I waited appx 1 hour) then you will be chaperoned to whichever dept you need.
My personal day continued like this. Full examination from a Cardiac specialist who spoke almost perfect English, blood tests, ecg & echocardiagram, all for 68tl. This was done & dusted by 11.30am, I was asked to come back at 2.30pm to discuss the results. Duly arrived back on time, saw the doc again, he wanted 1 further test done which the Devlet didn't have the facility for so I had to go to the Esnaf, the appt was made by the tourism office on my behalf. Quick dolmus ride, treadmill test done (90tl) & back home.
At all times the tourism staff are there to help, they popped back several times whilst I was waiting to see the doc to make sure I was ok & once he had asked for the further tests the lady was with me all the time to make sure I was seen promptly.
I would have no hesitation in recommending the Devlet & the staff to anyone. I have been having some chest pains & to get all the relevant tests & results in 1 day seems unbvelievable to me. Thanksfully they have found nothing wrong so I'll be here to annoy you all for a bit longer!
On a personal note I'd like to thank Fastlady (Janet) for going with me to show me the layout in the first instance, much appreciated.
