MICROBIOLOGY OF OSTEOMYELITIS AT THE OXFORD BONE INFECTION UNIT: MRSA RATES FALLING
2018
Aim This study quantified changes in the microbiology of osteomyelitis in a single specialist centre within the UK. The rate of infection with multi-drug-resistant (MDR) bacteria was measured over a ten year period in 388 patients. Method Patients with confirmed osteomyelitis who received curative surgery from 2013–2017 were included (n=222). Microbiology was compared to patients from a cohort between 2001–2004, using the same diagnostic criteria (n=166).1 The proportion of MDR bacterial pathogens2 from deep tissue culture in these cohorts were compared. Pathogens were analysed according to aetiology and the presence of metal-work. Results Both cohorts had similar baseline characteristics. A median of five tissue samples were submitted for each patient. The proportions of specific pathogens remained unchanged between the two cohorts, with the exception of a decrease in the proportion of coagulase-negative Staphylococcus (CoNS) (12.7% vs 5.3%, p<0.05). Although the overall proportion of Staphylococcus aure...
