dependent on kindness. The medical establishment should be dealing with this within their protocols. They already know about "pump head," though they don't like to talk about it. And beyond that, the idea that people will experience something they may never fully recover from, simply because they have had to go to the hospital, should certainly suggest a rethinking of the system.
I have experienced within my close family, several different examples of permanent severe negative changes to old people who have been in the hospital in situations where the surgery or procedure or cure was pronounced completely successful. My mother, my mother in law and my father have all experienced "highly successful" outcomes from which they were never anything like themselves afterwords. They lived in a state of diminished health and transformed personality for several years before they finally died. In each case, the medical professionals were very excited at how extremely successful the care had been, and what great patients they had been.
It has come to the point where my husband and I have agreed we will not go to the hospital for any reason after age 75, and we will think very hard before we would go in for any reason starting now (at age 68).
