Graduated last year from a program that was probably a tad bit more intense yet not super intense and pretty front-loaded. Here's what I remember.
PGY1 -- psychiatry inpatient (6 months): ~55 to 60 hours/week, IM inpatient (2 months): ~70 hours/week, ED (one month): ~18 10 hour shifts, outpatient medicine (1 month): 30 to 40 hours + no call (awesome!), neuro (2 months): ~40 hours (one weekend per month of daytime call)
PGY2 -- predominately all inpatient + consults + state hospital: probably 50 to 60 hours/week overall -- closer to 60 or more on consults and busy inpatient weeks, closer to 40 at state hospital. On call ~2 weekends/month. Nightfloat for 6 weeks, which was straight 60 hours/week yet pretty chill. This is the hardest year in my program.
PGY3 -- 40 to 50 hours/week if you include documentation/administrative stuff after clinic. Weekend call ~ every 4 to 6 weeks. Otherwise, free nights and weekends.
PGY4 -- 30? hours/week. No weekends or evenings. Almost all electives.
Wow, moonlighting 15 to 20 hours/week! Easy phone coverage stuff, or real actual work? I'm too lazy for that. I worked about 12 hours/month moonlighting as a PGY 3 and 4, which was about typical for most of my fellow residents. Or people would do one weekend a month at a hospital.
