LOL. I can only assume you've never been at a well run ACT practice. We supervise between 1:1 and 4:1 depending on the cases. The answer is always that it depends. And I talk quite frequently with colleagues at residency programs and they share horror stories of what they end up covering and with who (and these are at "top 5" and "top 10" programs by any measure).
As for the surgical world ending in the US, it's simple math. My entire state would shut down and so would many others. Surgical volumes would plummet. Does it work in the west? Sure, because the staffing is already in place. You can't just transition the majority of the country from ACT model to MD/DO only care. There aren't enough anesthesiologists. How many get board certified per year? 1200 or so? 1400? You'd have to probably double the number of grads per year and it'd take about 20 years to catch up to the demand that would create. So all those surgeries people can't have aren't exactly "unnecessary". You'd have to ration care drastically.
And nevermind the simple fact that ACT model is proven safe and effective so why bother with trying to get rid of it? The best study ever done with mortality data comparing physician only to ACT model to CRNA only found ACT model had the lowest overall mortality rate (I believe it was from the 70s and 80s from North Carolina data but I'm too lazy to find it right now).
Honestly, right now I can't even think of what ACT stands for. And I can't find studies comparing the three models. But maybe you can find them for me, because honestly I can't.
It works for you. Great. You get bored doing your own cases. I get it. Sometimes I do too. I have only been in one ACT model where I supervised mostly 2 sometimes three rooms, and when I had 3 sick ones or 4 healthy ones, I still felt like I was running around like a chicken with my head off not knowing what was going on in each room and walking into a few disasters with CRNAs who thought knew it all. But hey, at least I had time to eat. I did make a friend who was a CRNA at this practice. However, she truly believed in having the physician there during the key moments and was very respectful and polite from the get go. We are still friends to this day. Plenty of CRNAs are not this way.
It's not a matter of trying to get rid of the ACT model. Its continuing this whole mantra of "it's proven safest and best" that really bothers me. Supervising 4 rooms of nurses, all with different level of skill and experience, with 4 sometimes sick patients like many of these large nationwide companies do, is not safe and beneficial to the patients. Oh, and then the patient gets two bills that they have no clue about. Even better.
We are fed that BS constantly and some, who benefit financially and/or enjoy the ACT model really continue to pass that along like it's golden. Is it really? Or is it it the money? Who did the study? No other first world seems to have this CRNA problem, does that mean they have higher mortality and morbidity since their docs are the ones doing the anesthetics?
I am sure your practice is one of the safest and efficient ones out there where if you do supervise 4 rooms they are all healthy appys, and choleys.
Like I said, maybe if we supervised no more than 2 patients at a time, then we could call it "the best practice". But anymore, seems a stretch that I am sure anyone benefiting financially from this model could come up with a study showing how this is the best level of care.
I found the ACT definition after adding anesthesia to the end of my search subject. But seems like all the studies I see are comparing cost effectiveness and not quality.
