Although I complain, hospitals in developed countries are still superior.
When I read about the interactions between the lab and clinicians in underdeveloped regions, it's way scary.
doctors are fallible
Yes they are, the practice of medicine should make one humble, but that doesn't seem to be the case many times.
In those places, you can have doctors that won't trust lab results due to ignorance or pride. At the same time, you could have incompetent lab personnel that fuel that distrust.
I have met doctors like this, and these are the doctors I tend to trust. Everybody is fallible :)
