In a hospital the standard of care changes over the years. 

If you had a cold in the late 1800s, your doctor would prescribe heroin as a cough suppressant.

 If you had schizophrenia in the 1930s, your doctor would perform a lobotomy. 

But despite the increase in knowledge and research, doctors still aren't perfect. 

Even today, your doctor's not likely to offer pain relief for an IUD placement, even though it can be more agonizing than a vasectomy. 

We expect doctors to not make mistakes. But the history of medicine is a history of flawed judgment. 

Beneath the white coats and fancy titles, medicine is just humans treating humans. The most brilliant surgeons have made questionable choices. 

No one gets it right all the time.
