Man, I have been waiting for you to chime in on this topic before I went and shattered everyone's dreams about just how great the imipenem....errr, Sanford guide is. First day of my new program, there was a new imipenem guide on all of our desks (conveniently bunched with the package inserts for caspofungin, imipenem/cilastatin, and fosaprepitant; you know, as a welcome present from our Merck representative). Everyone got excited and tossed them in their lab coats; I immediately tossed mine in the trash. They were all perplexed. I informed them that I did not need a guide to tell me how to recommend/order imipenem/cilastatin for every indication under the sun. This made for great first impressions.
In fact, I rarely can think of any setting PERIOD that I would recommend imipenem/cilastatin (rare occasion = cefepime insensitive acinetobacter, but even then I am not completely sold).
