Personally if I was ever injured permanently or couldnt practice EM, I really would enjoy Palliative Care. Wouldnt be lucrative but at that point Id have disability income as well.
Otherwise UC will likely be where I go when I want to retire for the most part, but dont want to stop entirely and fully dip into my retirement money. That or just work a few ED shifts here and there at a sleepy place.
As for a backup if EM totally melts down in the next 10-15 years, I dont have one. I dont see it totally melting down. I make 100k more now than many of the salaries I was looking at a decade ago in my region of the country. If all of a sudden I made 100k less, Id be pissed, but it would be exactly what I expected to make when I went into the field. I wouldnt leave. And I dont see that happening anyway. At least not in more rural America. For all the doom and gloom about over saturation, my region of the country still has a hard time recruiting physicians.
