It really depends on what your institution in and of itself does. There are probably some great private schools...I just know what up in my neck of the woods.
Hardest rotation?
Typical day is 10-11 hours, monday-friday.
Get there at 6:45AM...print off patient profiles on your acute care service. (15 or so patients)
Catch up on all of them, read what happened overnight. Think about recommendation you need to make, etc.
7:20, go to check-in/prerounds. Catch up on the stories about the new patients from medical team. Review their home meds, make recommendations on the spot.
7:45-9AM - do chart reviews, check out the AM labs/vitals from that morning.
9AM - Preround discussions, talk about every patient in depth, be prepared to answer any question the attending physicians/residents throw your way.
10-12AM - Rounds, visit each patient, observe stuff, answer more questions on the fly.
12-1 - Lunch
1-3 - Research on your own about the things the pharmacy preceptor/attending/residents made you look up. It's never enough time to do it all, sadly. You do the medicine teams stuff first, then take your preceptor's stuff home for tomorrow. And it;s the type of stuff that takes a few hours on pubmed to get correctly.
3-430 - Meet with pharmacy preceptor, discuss what you've found that day about the patient, give them updates on labs/findings/whatever
430-515/30 - post rounds, discuss patients with medical team, etc, etc.
Then you also had to do two 15 presentations during the weekly internal medicine grand rounds about the subject of the attending physicians choice. Those attending include 5 attending physicians, 5 pharmacy preceptors, a slew of residents, and several medical students.
Also, once every 4 days, you had to come in at 545 to do the "night float" admissions with the medical team. That sucked balls. On those days you were there dang near 12 hours.
And I had four of those...while the above was the hardest, all four were in the same league as each other. It really, really sucked, but it DID prepare me for the real world rather well.
