Over here the medical staff is extremely overloaded. And they work very hard.  They really don't have the time to explain the same stuff over and over again to the next patient who is overwhelmed by medical speak.  The nurses did all they could (as far as it is allowed). It all looks great, until you start to question why certain things are not allowed. Why is a corporate nutrient drink that tastes as horrible as it smells being pushed as if it is something magical.  While the hospital food is not as nutritious as it could be.  My day survived an aneurysm several years ago so i'm grateful that the medical system rescued him and gave him a second chance.  Though it seems that the blood he received is the reason he got leukemia later on in life.  Its just the things that you notice that are there for 'corporate reasons' and those push actual healthcare on the side.   To some extend healthcare seems to have turned into a one size fit's all system. And if it doesn't work for you, ah bad luck...   Or if youdon't want certain 'standard' chemicals being pumped into your body then there simply is no alternative.
This is how we repair an engine, ... with a hammer. deal with it...  :-)
And for an aneurysm that indeed works. Much respect for the brave people who just cut, dig up the leaky pipe and jam a silicone tube in to fix it, and stitch everything together again.   It's just that corporate reasons should not make the rules.

The medical jargon just doesn't make sense to people who are rushed into a hospital then get an emotional experience and on top need to digest all the medical speak they never had to deal with.  This makes it impossible for elderly people to make decisions

First they are happy to open their eyes an be alive.
the next second a specialist overwhelms them with words they never knew existed.
then the next person waters it down into layman's terms that cause even more confusion.  My dad would say, why speak Latin to me? i'm in a Dutch hospital, right?
And right after that the family rolls in with all kinds of questions. Add bad hearing, and people who just don't really listen.  And an already exhaused patient is confused to the max by all the chatter.  Happy to be alive, and happy to have the people around. But unaware that the information is getting lost on the spot. 
Then the next day all that confusion is in the mind. And then the specialists come back to 'make a decision' And as the patient is lost for words the specialist just do what is common. And all is done and dusted.   
Not really anyone's fault.  But if the first explanation had been in 'normal' language that the patient had been able to comprehend then things would have been a lot less difficult for the patient.  
It's stuff like that that seems to go under the radar.  As all people do this. If a car mechanic explains how to fix car he basically does the same. :-)
No hard feelings to anyone,i'm grateful that there are so many people who really go trough great lengths to save other peoples lives.  It's often very underestimated.
