More relevant to thread topic I've come close to reporting a fellow physician twice:
1. My wife had our first kid and had some post-partum complications while I was on my IM rotation. Took her to our local ER a week after d/c from the hospital d/t concerns for a PE. She was medically cleared and couldn't have been happier with her care, the whole team was fantastic. A week later she got extremely pale, like paper white with lips being the same color, and was short of breath. Took her back to the same ER and got a different doc, he looked at her vitals which were stable and was going to d/c without any further work-up, didn't even order labs or do a physical.
I mentioned I was an intern and asked if it wasn't standard to at least get a CBC and he got labs but no imaging. Hgb was ~6.5 and it had been around 10 the previous week. He said that it wasn't an issue and whenever he calls the OB/gyn they say not to worry about it as it's probably just still post-partum bleeding (2.5 weeks after birth...). Meanwhile, she's oozing blood from her c-section wound. When I pointed it out, he did a 10-second physical exam on the wound (only physical exam he did the entire encounter) and used liquid sutures to try and close it without actually cleaning the area WHILE IT WAS ACTIVELY BLEEDING. Said it was fine and discharged her. Couple hours later she's still feeling awful, the sutures have oozed away, and I'm still worried.
So I called my senior resident who was married to the OB/gyn chief resident where our kid was born to ask if I should take her somewhere else. His wife said to take her straight to their unit/office and they took her straight upstairs for exam. U/S showed she had a 7x13x3 cm hematoma near her open wound and IR got a stat consult with transfusion. She got admitted for 2-3 days for obs and stabilization. Every doc I talked to at that hospital was flabbergasted that the ER doc discharged her. I got talked out of reporting it by family because I was still an intern, but wish I had. Looking back the level of neglect still disgusts me.
2. A few months ago I had a situation in our ER that was more of a psych/legal issue that more pissed me off than anything. Patient took her highly inebriated husband to a different ER and while there became extremely agitated when they wouldn't let her back to talk to him. Apparently when hospital police arrived it triggered her PTSD and she lost control and attempted to strike several officers. So instead of taking her to jail they placed her on an involuntary psych hold in their ER, put her in an ambulance, and sent her to our ER because admin "banned her" from their ER the same day. Basically was an EMTALA violation as they have all the same level of services that our hospital does with a full inpatient psych unit and everything. I didn't file a board complaint on advice from out legal/RM teams, but it did elevate to risk management who are apparently dealing with the state regarding the issue. The other hospital is notorious for discharging patients from their ER who need admission (hospital has a psych unit at their facility) and then patients coming straight to us for admission, but this was the first time they'd actually broken a law in doing so.
I've seen plenty of other situations where the med management was just so awful that I wanted to report, but haven't because as others pointed out the standard of care/standard of what is unacceptable is absurdly low.
