i was browsing through some anesthesiology program websites and found out that most programs require that we do a year of training prior or additional to our residency. what does that mean? and what kind of training do they require? Also, what is the CA-1? is it the same thing as PGY-1? i am all confused. Initially, i thought that MS4 can match into anesthesia directly. seems like some programs only take PGY-2?
