I'm just a 3rd year student, but I'll help you out as best I can--
The program is very much academic-oriented, with formal rounds every morning, etc. Residents and students are constantly drilled with the evidence-based medicine manta, and research/data are always being cited -- you are expected to be familiar with the major trials that back up the treatments we give patients.
Morning report monday through thursday is run by the chiefs, it is generally case-based and always pre-prepared, and takes place before rounds. Friday AM is grand rounds, which is invariably some bleeding-edge bench-to-bedside research that is way over this med student's head, but seems to be well-received. Noon conference is generally topical, and is either presented by one of the chiefs or a resident. FIRM confence takes the place of noon conference on Thursdays, it is presented by one of the teaching attendings, and generally consists of presenting zebra cases or the data and research behind disease treatment regimens.
Each ward team consists of a teaching attending (one of the academic faculty), a resident, two interns, a sub-I, a couple 3rd year students. The teaching attendings are on service for two weeks at a time and are completely dedicated to teaching during the two weeks they're on service. This means they're around to do teaching if there is time in the afternoon while we aren't on call. The hospitalists handle overflow patients.
Except for the hospitalists, the medicine service is entirely resident-run in the sense that private attendings can not admit at the hospital unless they come in and do all of the work themselves.
At any rate, I spend six weeks at NMH and six weeks at the Evanston hospital (which has an entirely separate residency program, and is a more community-based affair). The NMH program is academically rigorous, almost to a fault. If that's what your husband is looking for, he'll certainly find it here.
