Look, you don't need any special electives. All you need to know is how to consult efficiently (not effectively though, that's beyond the scope of this post):
Got multiple consults to call? Well the order is important. You're gonna want to page surgery/IR first, as they are in the OR and won't call you back for several hours. ID and renal should be next, because although they'll get back to you quick, they have like a million consults, so best to be on top of the pile. Made it this far? Well it's time to call rheum, and they probably didn't remember to turn their pagers on, so you'll need to get their cell # from the operator. Hey, that's what happens when you only get consults on leap year. While working on that I recommend getting a palliative consult (if you're impressed I knew you needed one, you probably also like those magicians who use math to "guess" the number you're thinking of). Psych should be consulted last because hopefully the patient leaves AMA before psych gets a chance to demand they be put on 1:1 (uh oh, there goes your length of stay metric!)
Ok, now that you're done with all those consults it's time for the real medical decision making -- selecting a DVT ppx. If you're too lazy to look for contraindications to heparin, you can just make it SCDs, but make sure to check that the patient doesn't have BKAs, because the nurse will probably page you at 2am about that. Also, you're going to want to make sure she didn't put the SCD on a prosthetic limb. You know what, ordering heparin is probably easier, scratch the SCDs, everyone gets heparin.
So now just combine the above with whatever you remember from residency and you're good to go.
