Any good programs in the Midwest have this?
On top of BlackNDecker's reccomendation of Mayo, I think it is also worth considering Wash U., UTSW and Michigan, especially if you are interested in research or academic medicine. Subspecialty fellowship matches from these programs also compare very favorably. Also noteworthy is Alabama and Iowa.
Most programs nowadays have a nightfloat system to comply with ACGME requirements while keeping hospitals to capacity.
I think you have to be careful what you are asking for. There are many circumstances where you suffer through inferior ancillary services (and hence more scut) with the tradeoff of having increased autonomy and incredible patient diversity. Many municipal hospitals (like Bellevue(NYU), Parkland(UTSW), etc.) and training programs located in inner city locations (like JHU) provide an amazing level of autonomy. Although you may not see it now, but it's a real rush being the doctor in charge and having first crack at procedures. The same can be said for programs affiliated with VA medical centers. Although ancillary services usually have much to be desired, the vets are a special breed of patients (tough as nails, tolerant of being poked around by trainees, multiple illnesses and very appreciative) whose disease profiles are becoming the bread and butter of community medical practice (diabetes, coronary artery disease, obesity/metabolic disorder, mental illness, COPD, GI bleed, HIV, etc.).
Housestaff happiness seem to change from year to year, and many residencies are continuously tweaking their training programs to comply with ACGME requirements while balancing learning experiences with quality of life. The best thing to do is apply broadly and talk directly with the residents (also go out of your way to find working residents and not just those who show up to volunteer for interview days. you want to avoid cheerleaders but talk with the average schmo to get the pulse of the place). Just remember, the most vocal people tend to be either complainers or cheerleaders. Try hard to get a fair and balanced opinion.
Good luck!
