Fellowships following the work hour rules? hahahahahaha.
Even if you are accredited, the extra work you will be doing as a fellow is often not 'trackable'.
Expect to 'work' 90-100 hours a week. Not all clinically. Networking, conferences, projects, reading, teaching, research, administrative, etc.
All will eat into your time.
Fellowships are labors of love. You get a concentrated amount of time to learn a subspecialty that will put you in a better position than if you are non-fellowship trained. But the price is hard work.
I don't know a single fellow, yet, who hasn't worked MORE than they ever worked as a resident
