High prevalence of clinical MRSA strains with elevated vancomycin MIC (2 microg/mL) requires aggressive empirical vancomycin dosing to achieve a trough greater than 15 microg/mL. Combination or alternative therapy should be considered for invasive infections caused by these strains.

FQ exposure from widespread prescribing is a modifiable risk factor for FQ resistance in P. aeruginosa. FQ empirical therapy for Pseudomonas infections may be associated with significant delays in administering effective therapy resulting in adverse outcomes.

Chronic pulmonary infections with

Non-albicans Candida species accounted for the majority of IC in caspofungin-treated patients. Improved outcomes were observed for patients initiated with caspofungin within 72 h of positive culture compared with those who received delayed therapy.
