I am wondering if anyone has any tips on how to improve my ID knowledge base. I get some of the most common abx regimens but I am frustrated that I don't remember specifics like what generation cephalosporins.

The EMRA antibiotic guide has a good overview for the common bugs and drugs broken down by site of infection.

I'm not sure the generation matters so much as getting a few down and knowing their side effect profiles and why we would choose one over the other.

Just try to learn a few clinical pearls from your ID rotation that will help you in the future.

Klebsiella is intrinsically resistant to ampicillin. Enterococcus is intrinsically resistant to cephalosporins. Cefepime has pseudomonas coverage over ceftriaxone. Zosyn has pseudomonas coverage over Unasyn. Zosyn and Unasyn have better anaerobic coverage over cefepime and ceftriaxone. Daptomycin doesn't go into the lung. Meropenem is good biliary distribution so can be used for cholangitis. Ertapenem is the carbapenem that doesn't cover pseudomonas. Fosfomycin really concentrates in the urine. Nafcillin is what you want for MSSA cellulitis but if the patient gets AIN or is allergic, you can go with cefazolin. Ampicillin for listeria. Know when antibiotics are enough and when you need source control i.e. surgery or IR. Etc. etc. etc.

Check out the IDSA website (Google "IDSA guidelines"). They have PDF guideline documents sorted by organ system and organism. They can be long but when reviewing broad topics such as endocarditis and pneumonia are good references.
