There were notes to the effect that I appeared to be mentally disabled and likely unable to understand discharge instructions, but that I was under the care of my mother, who would be able to handle them for me. I was apparently not at my best at 3-5 AM, after spending several hours there in agony, and with NO pain management. My mother was there had recently arrived to advocate for me, after I had been unable to get any pain management or any other care, and was being treated worse than an animal.
This judgement about me was made without questioning either myself or my mother.
They also put in my notes that I told them my sons were conceived through "immaculate conception" when I would actually have told them that it was IVF and frozen embryo transfer.
They also got the medications that I was on wrong, in particular an MAOI that had the potential for dangerous or deadly reactions with a number of common medication. Other medications, they got right, but made up the dosages.
Even the discharge instructions were off the wall. I was instructed to contact a particular nurse for some sort of followup, and given her name, phone, and location (hospital and floor). I dutifully called and got her charge nurse who couldn't understand why someone was trying to make an appointment with one of her ordinary floor nurses.
I personally strongly recommend obtaining this information because God only knows what kinds of things they're saying about you, and how completely batshit their overall info about you may be.
Needless to say, it did not improve my level of trust in the providers, and in fact left me with a profound mistrust in both their competence and in their basic human decency. It did not improve my knowledge of my own health.
After that experience, I'd say that I would be far less likely to go to an ER again if I could possibly avoid it.
Anyway, that's my experience.
