well I am pure private practice pulmonary now
I work 9-5PM though I am often staying after hours to write PFT/CPET reports, finish office notes, fill out DME/O2 forms etc...
My partners and I alternate going to the hospital before 9 and after 5 if we have patients hospitalized (we don't have too many patients hospitalized at any given time fortunately)
When i worked at a NYC community hospital with a fellowship program for a brief while before, the hours were 8AM to 4PM. When on ICU, the usual round with team from 9AM to 12PM. attend conference. do any bronchs in afternoon. attend fellows clinic. wrap up by 4PM. attending ICU call q8 days over night phone call with fellow in house on night float. no night intensivist coverage in this hospital.
