That’s funny. When I was in med school and then residency, no academic attending would ever work alone. It was unheard of.
Now many years later there is a large percentage of academic attendings working alone any given day. And the trend keeps growing. It is actually expected for new hires to work alone many days of the month.
What you spout a truth does not match reality.
At my former residency program, there are less than 10% solo attendings on any given day nowadays. There used to be many more 10 years ago.
The main reason some academics work alone is the lack of CRNAs in those programs (the hospitals have grown in the last 10-20 years much more than the approved number of residents). Greed is a very strong human motivator, so I don't think this will last for long even in areas where solo MD anesthesia is still dominant.
And the main reason an ACT shop would hire solo MDs nowadays is the lack of good CRNA candidates (and stupid young grads are only slightly more expensive for "instructor" positions in certain cities). There is a sucker born every minute; those are not good jobs.
Also, once an academic place turns ACT, it will stay ACT, because many academics will lose skills after supervising for years (beside money, money, money!). So, while they may use a few recent grads to fill the holes or for overflow, their long term plan is not solo anesthesia.
Anyway, this is going off-topic, just to satisfy some egos. Let's just agree to differ. There are few people I would recommend anesthesia to, and clever introverts who have better choices are not among them. And, as in the real world, I could care less what entitled residents think, whether they are 30 or 50 years old. They ain't seen nothing yet. As for the medical students, they should not jump into any specialty based on what they read on the Internet.
