There's a 0% chance doctors don't talk shit with each other about patients, just like in every other service profession. They literally talk shit about patients on charts sometimes.
The unethical thing would be if they revealed protected information in the process.
My sister doesn't talk specifically about patients by name, but she'll say things about what she told someone to do that they didn't, and the consequence was exactly what she told them. Stuff like that.
Interesting. I'm going to need to hear from more people if I'm going to buy that's standard, though.
There's established medical acronyms like "Funny Looking Kid" or "Get Out Of My ER". The stress thing depends heavily on specialty once out of residency, and a stressful job can actually mean more story time once they're done with a patient - just ask a paramedic.
