Non-susceptibility in S. aureus: % MRSA (≥ 48 hours in hospital) BSAC: Respiratory 2008/09, Bacteraemia 2008

Non-susceptibility in S. aureus: MSSA and MRSA (≥ 48 hours in hospital)

Non-susceptibility in Pseudomonas (≥ 48 hours in hospital) BSAC: Respiratory 2008/09, Bacteraemia 2008

Conclusions In infections after ≥ 48 hours in hospital: Resistance rates are broadly similar in blood and respiratory infections for most organism-agent combinations...BUT differ substantially in some cases. Klebsiella and Enterobacter are more prominent (among Enterobacteriaceae) in respiratory infections than in blood. Direct surveillance of resistance in specific infections and settings is preferable to extrapolation when possible.
