The support from the clinic since I started treatment has been brilliant
What worried me most was what haemodialysis would actually be like and how I would feel. But my doctor was honest about what to expect and explained the whole process very clearly, including the diet and fluid restrictions. As it turns out, I feel better than I expected. I’ve been prescribed three sessions a week, and the support from the clinic since I started treatment has been brilliant. They’re always available, they’ve checked in on how I’m feeling and given me clear instructions. Importantly, there were no additional costs. My advice to future patients would be to prioritise their health above all else.
Everything's fine.

Thank you to your organisation and to you personally, as well as to Angelica from the host organisation, for your help!
I suppose I’d give it a 4.8, really. But that wasn’t down to you. The doctor saw me an hour and a half after the scheduled time. However, the consultation was very informative. Thank you to your organisation and to you personally, as well as to Angelica from the host organisation, for your help!

Given how positive my experience was, I would definitely recommend this clinic to anyone needing similar care
My biggest concern was the anxiety around getting a full-body CT scan, but that worry disappeared quickly. From the moment I walked in, the staff made me feel comfortable and explained every single step, which was incredibly reassuring. The clinic was clean and organized, and the medical team was both professional and genuinely kind throughout the entire process. Everything went smoothly. Given how positive my experience was, I would definitely recommend this clinic to anyone needing similar care. I'm grateful for how they handled my case with such efficiency and compassion.

My experience has been entirely negative. The treatment prescribed did not follow the standard protocol for this condition. Under this treatment, the condition only worsened. I was given information about the most effective treatment currently used worldwide. I never received the doctor’s conclusion following the consultation, even though I asked for it several times. And on top of everything else, judging by the result, it wasn’t worth €500. A treatment that doesn’t work, with no documentation whatsoever. Just a conversation with a professor to whom you have to ask a thousand questions and figure out the treatment options for your condition yourself, because he offers nothing and explains nothing.
Speed of service delivery
The treatment recommended by the professor at the Austrian clinic was completely at odds with standard treatment protocols I never received the discharge summary, even though I had asked for it several times
