That's exactly the issue. 80-90% of the cases are the easy cases even in rural hospitals.
They will punt the more challenging cases. So if u do bread and butter 80-90% of the time. Who wouldn't want to do bread and butter.
If they paid u X amount and u get to do bread and butter all day getting paid the same X amount to do 30% complex patients at another place.
What would you choose? So they keep doing easy cases. Collect their pay checks. Low liability. And still get to claim they are just as safe as MDs.
I'm not arguing they are "just as safe as MDs". I'm saying the opposite. I'm just telling you what actually happens. Plenty of small hospitals have 1 anesthesiologist supervising CRNAs, but you can't have somebody on call 24/7/365 so there are periods of time in a week where there is no anesthesiologist coverage and the surgeons are legally responsible for the CRNA. What happens in those situations is the surgeons will only do the sicker patients/bigger cases during times when the anesthesiologist is around. If it's something that can't wait, they transfer the patient to another facility.
