AbstractMethicillin-resistant Staphylococcus aureus (MRSA) infections are associated with increased mortality, costs and length of stay compared to non-MRSA infections. This observational 4-year study analyses the impact of screening and treating orthopaedic healthcare workers for MRSA colonisation. A total of 1,011 swabs were taken from 566 healthcare workers. Positive healthcare workers were treated with topical mupirocin to both anterior nares. The prevalence of MRSA colonisation on initial testing was 4.77%. The rate of positive MRSA colonisation of those tested on more than one occasion fell from 5.88% to 2.71% (p = 0.055) on subsequent screening. All healthcare workers receiving treatment were successfully cleared of colonisation; however, some required more than one course of treatment. These results show that there could be a role for screening and treating orthopaedic staff for MRSA colonisation as part of a strategy to reduce the prevalence of MRSA infections in orthopaedic units.
