A bad outcome is not necessary to make it a violation. I think you are confusing potential malpractice due to delay in care, with EMTALA violation. They are two separate processes of medico-legal liability.
EMTALA aside you would consider the patient from the original question a "liability dump that needed discharge?" The patient has by the description sepsis secondary to a potentially necrotizing wound infection with a large abscess. I mean even if they are not crumping right this second with hypotension and altered mental status I would still consider that a potentially "sick" patient. I would think surgical debridement is fairly emergent in this case.
Well, I agree, this is where it gets really hard. The "Text book" answer is you demand an in person consult by the specialist in question, and IF after they see the patient they say it requires a higher level of care, so be it. Or you call them on their bull **** and demand they do what needs to be done.
But in reality, you are going to burn a bridge with a surgeon/specialist the hospital probably esteems more highly than you the ER physician (viewed to be a very replaceable cog), and you may ultimately piss away a lot of social capital with your hospital. That may blow back on you in problematic ways down the line.
Ultimately I feel it's not up to us (ER docs) to tell specialists what they can and cannot do. We merely have a duty to notify the most relevant specialist we have. I would say in the exception of exceedingly obvious examples (general surgeon says they cannot manage acute appendicitis, gynecologist says cannot manage an ectopic pregnancy) if the physician says they "can't do it" I kind of have to take that statement at face value, and all I can do is document that. If the receiving hospital wants to file a violation against me for "allowing" the transfer, I'm kinda stuck. All I can hope is they recognize in my documentation that the impetus to transfer was initiated by the specialist who said they were incapable, and the OIG and CMS can decide if that was appropriate behavior from the specialist or not.
A classic ER "lose-lose."
Send the patient POV to hospital for appropriate timely care: EMTALA violation.
Keep the patient awaiting appropriate space and transportation to be mindful of EMTALA, patient dies due to "delay in care:" medical malpractice suit.
Do any of the enforcing entities care that the healthcare system has collapsed and does not have appropriate resources to provide the care they require? No. This is why moral injury in this specialty is so pervasive and burnout exists.
