Controlling the risk of MRSA infection: screening and isolating patients.

Methicillin-resistant Staphylococcus aureus (MRSA) continues to be a major cause for concern to health boards and trusts through the UK and the rest of the world. A review of literature sourced via Cinahl, Medline and Pubmed examines the discussions for and against screening patients for MRSA and isolating MRSA-positive patients as a means of managing MRSA within the hospital setting. The research evidence available on the ability of MRSA strains to spread within the healthcare setting and how this influences the opposing arguments is explored. Other factors considered when examining the arguments for and against screening and isolation are: the implications both in cost and resources; the effect of MRSA infection on patient morbidity and mortality; and the need for individual risk assessment of MRSA colonized or infected patients to prevent the transmission of MRSA isolates. The arguments raised lead to the conclusion that screening and isolation should be universal to decelerate the rate of transmission of MRSA.
