Is MRSA admission bacteraemia community acquired? A case control study.
Cases of MRSA bacteraemia admitted to general medicine between 2003 and 2006 were identified and compared to MSSA controls (35, 35 and 34 patients, respectively). 34/35 strains of admission MRSA bacteraemia were healthcare associated, whereas 20 different MSSA strains were identified. No MRSA cases fitted the CDC definition of community-acquired MRSA. MRSA cases had significantly higher levels of previous hospital exposure than MSSA controls, and more co-morbidities. Notably, 63% of MRSA cases were admitted from their own home, as opposed to secondary care facilities. It was concluded that MRSA strains associated with healthcare were responsible for almost all cases of MRSA bacteraemia on admission to hospital. J Infect. 2008;56:163-70.
