My wife's brother, who lives in Munich, say, that it is impossible to leave bad review for doctor or hospital, because here is court decision, that patient is not qualified (doesn't have education and training) to distinguish good medical service from bad one!
I was referring more to a patient not being able to discern whether or not a certain diagnosis or treatment plan is the best option, just as they would not be able to with a car mechanic.
I was more meaning that from the patient’s perspective, it’s hard to tell the difference.
It helps that I live in NZ where you can’t sue very easily for injury, and most medical errors are covered by a national insurance scheme which applies to everyone.
When one doctor says "it is some muscular spasm, take painkiller and wait" and other one remove stones from my ureter (true story), I know that first one didn't give me good medical service, for sure.
Or if doctor starts to speak about homeopathy, osteopathy, thin energies, some concepts from ayurveda (one doctor in expensive clinic with good reputation to my ginger wife: "You are red-haired, so you warm woman, you need to shift your diet that and this"), you don't need to be MD to understand, that it is bullshit, and this doctor is not very good one.
