FUE hair surgery and hospital location

[Mike2020]

If looking at HT surgeons who can undertake FUE in Eastern Europe and in Turkey, would one criteria for selection be that you should only use a surgeon who is going to undertake the surgery within a hospital?

Are Eastern Europe and also the top clinics in Turkey (the best ones which are often mentioned here on the forum) located within a hospital or are their clinics located separate from a hospital?

Thanks.
