Publicly available data for all National Health Service hospitals in England were used to examine whether there is a link between hospital cleanliness and rates of meticillin-resistant Staphylococcus aureus (MRSA) bacteraemia. It was not possible to demonstrate a consistent relationship between hospital cleanliness, as measured by weighted Patient Environment Action Team (PEAT) scores, and the incidence of MRSA bacteraemia. The large sizes of the data sets make it unlikely that a true correlation was missed. While a high standard of hospital cleanliness is a worthwhile goal, it is not helpful to repeatedly link MRSA control measures with improvements in standards of environmental cleanliness.

Randomized Controlled Trial
Impact of treating Staphylococcus aureus nasal carriers on wound infections in cardiac surgery.
Staphylococcus aureus is a common cause of postoperative wound infections, and nasal colonization by this organism is an important factor in the development of infections. Treatment with mupirocin can eradicate the organism in the short term, and prophylactic treatment of colonized patients may prevent postoperative S. aureus infections. A double-blind, randomized, placebo-controlled trial was performed to determine whether nasal mupirocin administered pre-operatively to S. aureus carriers reduces the rates of sternal and leg wound infections after cardiac surgery. ⋯ Among patients receiving mupirocin, 106 (81.5%) cleared S. aureus compared with 59 (46.5%) patients receiving placebo (P<0.0001). There was no significant difference between intention-to-treat and actual treatment groups. Prophylactic intranasal mupirocin administered to S. aureus carriers did not reduce the rates of overall surgical site infections by S. aureus, and only showed a trend towards decreased incidence of nosocomial S. aureus infections.
