I think q4 call with post call days Is a lot better than endless strings of night float, actually.
Agreed. Our prior schedule for junior residents wasn't a strict q4 or q anything schedule, but typically it amounted to 1 (rarely 2) weekday calls and 2 weekends a month (one Friday/Sunday and one Saturday). Postcall days off were when I got my grocery shopping done, ran errands, went to the dentist, etc. I have no problem going with little or no sleep for one night when I can catch up the next day. Additionally, the typical arrangement was that if you were precall, if you had your service tidied up and everything tucked in, the oncall person would take the pager for you starting at around 4. Everyone did this for everyone, so it all evened out.
Now, with night float, I find that I am much more tired. I'm sometimes at the hospital a few hours less during the month but I'm there M-F 5a-6:30/7p. This leaves very little time for the rest of life. By the time I've tried to go to the gym/eat dinner/read a few pages/shower, its past my bedtime again and I feel more perpetually short on time and sleep than I ever did under the previous system. Still taking call two weekends a month, though now its either working straight through on days (but covering multiple services), working nights, or, in the case of our 2nd/3rd years, taking a 30-hour call on Saturday so the interns can work Friday night/Sunday morning. Its complicated, there are more handoffs, and you're typically taking call for services you are not otherwise seeing during the week (so you only see them every other weekend on call) which makes it MUCH harder to know the patients on those cross-cover services than it was when you took call at least one weekday every week.
Nightfloat is miserable IMHO because you are not really involved in the real care of the patients. You're the guy who puts out fires in the middle of the night, cleans up the crap that didn't get taken care of during the day, and you're always worried that any significant decision you make, if not specifically instructed on the possibility at signout, will interfere with the day team's overarching plan of care. I'm in Surgery and on nightfloat there are even fewer opportunities to be in the OR than usual for a junior resident. At my program nightfloat is Sunday-Thursday; you have every Friday & Saturday off, but I wasn't able to switch back to days for just 2 days and thus was wide awake when everyone else was ready for bed. Sure, I had "off" but it was a miserable lonely time.
I have done both overnight call and the system currently in place and I suppose everyone who has done both can have their personal preference - but IMHO the current system is far worse for junior resident fatigue and morale than "traditional" overnight call with postcall days off. We'll suck it up and make it work because that's what we do, but I would jump at the chance to go back to the old system and I suspect the majority of residents who have worked under conditions similar to my program's previous schedule would agree.
