Whatever English they speak in "Bangkok Hospital" my guess is that in any mid tier Malaysian hospital they speak and communicate better. My wife went to Bangkok Hospital 2 months ago to get her tests done for Canadian permanent residency. Besides a basic conversational English I was surprised that the hospital is starting to look very neglected in need of repairs. Oh, but they have a piano player in the lobby,
However, I will admit that so far the hospitals I visited.... and I will put them here, Medpark, Vejthani, Ramkhamheang I never had any problems. The last ensoscopy I had at medpark was literally like waking up from sleep. No issues whatsoever, no nothing and the instruments they use are of course modern as it is a new hospital.
My problem is Thailand is what happens if something goes wrong? For the price you pay the hospital should take the responsibility and from what I read they never do.
Also, some doctors I saw are stuck in their ways and are not open to any discussion or opinions. I guess it is that face saving thing again because they know best.
