Timely detection of MRSA carriers is crucial to an effective isolation policy. In this issue Harbarth and colleagues report rapid MRSA screening among intensive care unit-admitted patients using a PCR assay. Preemptive isolation for all admissions until screened negative for MRSA was associated with a reduction of intensive care unit-acquired MRSA infections in one of two study units. The data provide preliminary evidence to the effectiveness of a MRSA control strategy combining rapid screening by a molecular method and preventive isolation. Further controlled studies are needed to evaluate the cost-effectiveness of this intervention. Evaluation of rapid MRSA screening and preventive isolation The study reported by Harbarth and colleagues in the previous issue of Critical Care is the first clinical investigation to evaluate the impact of a novel molecular assay for rapid screening of methicillin-resistant Staphylococcus aureus MRSA carriage in the intensive care setting 1 . The authors conducted a multistep intervention cohort study over a period of 32 months in two adult intensive care units ICUs in a university hospital. During a baseline phase screening for MRSA was performed by culture methods in high-risk patients admitted to these .
