A systematic review of the evidence for interventions for the prevention and control of meticillin-resistant Staphylococcus aureus (1996–2004): report to the Joint MRSA Working Party (Subgroup A)

SummaryA systematic review was undertaken of the evidence published between 1996 and 2004 on the effectiveness, and associated economic costs, of a range of interventions to prevent and control the transmission of meticillin-resistant Staphylococcus aureus (MRSA) in hospital settings. The review questions focused on screening, patient isolation, use of decolonization strategies, feedback of surveillance data, and environmental hygiene interventions. The reviewers assessed evidence from four recent systematic reviews, 24 non-experimental descriptive studies, five economic evaluations and one recently revised international guideline. The methodological quality of studies retrieved was such that there is currently insufficient high-quality evidence for infection prevention and control interventions in the fields identified for this review. However, evidence from clinically based, non-experimental studies does provide support for the continued use of a range and combination of interventions that contribute to the prevention and control of MRSA within acute hospitals and long-term-care settings. Well-conducted economic evaluations reporting the economic benefits arising from infection prevention and control interventions are lacking.
