Abstract
The objective of our study was to assess the efficacy of infection control measures (pre-admission screening and patient segregation) on reducing inpatient exposure to methicillin-resistant Staphylococcus aureus (MRSA).
A prospective case-control study was undertaken, analysing all admissions to three wards over an 83-month period from September 1995 to July 2002 inclusive (a total of approximately 34 000 patients). An orthopaedic ward with active infection control measures was compared with two controls, an orthopaedic ward with no measures and a general surgical ward with no measures. A statistical analysis was performed of the difference between the 3 wards in numbers of new cases of MRSA infection or colonisation. There was a statistically significant difference in numbers of new cases between the ward with the active infection control measures and the two control wards.
The infection control methods described are shown to reduce the exposure of patients to MRSA, which is of importance in orthopaedics, and has further benefits that may be applied in other surgical specialties, notably the choice of antibiotic used with the associated risk of side-effects of the specific anti-MRSA agents, the cost for surgical prophylaxis and patients’ confidence in the admitting surgical unit. As a useful by-product, such segregated inpatient beds are effectively ring-fenced, ensuring availability even during a hospital bed-shortage.
