I am currently a resident... This are the ED shift breakdown...
JHH (downtown): intern: 19-21 shifts, about 13-15 of those are 12's, the rest 8's; 2nd yr: 19 shifts, about half are 12's; 3rd yr: 17-18 shifts, only 5-6 12's, 2-3 6 hr, the rest 8's
Bayview: 18 shifts, mostly 12's, 2 months in 2nd & 3rd yr
Howard county adult as pgy3: 14 shifts, all 8hrs
Howard county Peds, intern and 3rd yr: 14 shifts, now all 8's
Pgy4's only work at JHH in a pre-attending role, 10-11 shifts all 8's. The rest of the time is spent in the FAST (the area of specialization for that year)
