These guidelines from the IDSA were released in 2009. Though they may seem dated they are the most current guidelines form IDSA on the topic. No new version is expected anytime soon.
There are almost endless clinical scenarios (suspected versus established infection, type of organism, patient characteristics, type of catheter) and treatment options (duration and type of antibiotic, lock therapy, removal versus retention). The guidelines, accordingly, are quite complicated, a bit more than you could be expected to remember. This is a reference the hospitalist needs to have handy.
