Psychblender's right. If I did a one year stint either overseas or as a chief, etc.
Cool, just wanted to make sure I understood your example. So, if I understand your specific situation correctly, this is how it would play out:
4 year HPSP, 1 year internship, 1 year(ish) GMO, 2 year residency...then
straight into a 3 year fellowship = 5 year obligation post fellowship (total AD time = 12)
4 year HPSP, 1 year internship, 1 year(ish) GMO, 2 year residency...then 1 year chief year, 3 year fellowship = 4 year obligation p fellowship (total AD time = 12)
4 year HPSP, 1 year internship, 1 year(ish) GMO, 2 year residency...then 2 year payback tour (BNPG goes back to a ship p residency), 3 year fellowship = 4 year obligation p fellowship (total AD time = 13 years)
4 year HPSP, 1 year internship, 1 year(ish) GMO, 2 year residency...then 3 year payback tour, 3 year fellowship = 3 year obligation p fellowship (total AD time = 13 years)
Or...4 year HPSP, 1 year internship, 1 year GMO, 2 year residency, 3 year payback tour and out.
Bottom line, doing a 3 year fellowship buys you 12 or 13 total years.
BTW, you'll be the best paid peds fellow in the US for those 3 years. Its a sweet deal to get paid as staff to be a fellow. If you wait until you aren't obligated prior to starting fellowship (the last scenario), you're eligible for MSP without increasing your obligation.
