Last year my program switched from call and cross-cover to nightfloat, and I was lucky enough to have both a call and cross-cover month, and some night float on the same service. And here's my head-to-head comparison:
Call and cross-cover
Pro:
- you get to follow your own patients through a full 24h period, which is an incomparable learning experience with respect to perioperative surgical care
- I think you own your patients a bit more when you're there, and consequently worry about them a bit more when the other team is on call
- you get that half day off to take care of all those chores that aren't compatible with life as a surgical intern (basically anything that has to be dealt with between 8am and 5pm)
Con:
- the 24-48h period of sleep deprivation is the absolute worst, and the length of call is right smack in the middle
- when you take sign out from the other team, half your brain is still thinking about your own patients, so you may miss something crucial that was said
- you will also never know the other team's patients as well as your own, and it's hard to educate yourself at 3am when you've been up for ~24h already, about all the things the other team forgot to tell you that are now hitting the fan
- the night nurses are completely oblivious to the fact that you've been awake so many hours, because they're all well-rested
Nightfloat
Pro:
- you are much more well-rested, and much less likely to let someone give you a vague and dismissive sign out
- likewise, if the patient's status deteriorates, you are much more alert, and able to gather and sort through information quickly
- you are there every night, not just every 4th night, so there's better continuity from one night to the next
- all the patients are equally yours for the night
- if there are emergent operations, you might still get to operate (I did)
Con:
- you don't get good quality sleep during the day, so you get progressively more tired as the assignment goes on
- you don't have any real say in patient management decisions, which can be frustrating if one of the day interns is an idiot
- because you aren't there on rounds, lots of blame gets heaped onto you that really doesn't belong there
- the day interns will take credit for any changes you made overnight that turn out well
-you need to know what you're doing already, because there's not much learning that goes on, and you can screw things up royally
So that's my list. Overall, I think night float is better for patient care, but not as good for resident education.
