MRSA colonisation in patients admitted with hip fracture: implications for prevention of surgical site infection.

In a prospective study we assessed 440 patients, sequentially admitted to the trauma unit with hip fracture. Of the 403 who had a swab on admission, 5.2% (21/403) were found to be colonised with MRSA. Fifty two percent of MRSA colonised patients were admitted from their own home, 29% from residential homes and 19% from nursing homes. MRSA colonisation was found in 3.6% of patients admitted from their own home, 10.9% of residential home patients, and 17.4% of nursing home patients. A high proportion (80.9%) of colonised patients had been admitted to a hospital within the previous one year, and the high prevalence of previous hospitalisation among people from institutional care may explain the higher rates of MRSA carriage among these individuals. When a patient gives a history of hospitalisation within the previous year, it is clearly sensible to consider the use of an agent such as teicoplanin for perioperative prophylaxis.
