So I've been looking into which Abx treat which pathologies and why. For instance, why do we love nitrofurantoin for UTI, but we rarely if ever give it for pyelo? I did the research, it seems the same bugs typically are involved with both with the exception of proteus, which has high resistance to nitrofurantoin and is susceptable to bactrim and rocephin. That's the sense I could make out of it anyway. I would love to have a stormer grasp of Abx and their coverage and what to go to in case of allergies etc. I use EMRA which I think is great, and I downloaded bugs and drugs which shows local SMS national resistance. I feel like my attendings have such a strong grasp of Abx and their coverage, I hate giving a med because "that's what we give for pneumonia." I really want a good understanding. Am I on the right track? Anyone know of a good app/website that breaks it down well?
