Cluster Randomized Trial of ICU:<br />
Demonstrated non-Utility of Culture<br />
• Assessed VRE and MRSA surveillance plus<br />
enhanced barrier precautions in the ICU<br />
• 5,434 admissions to 10 intervention ICUs, and 3,705<br />
to 8 control ICUs over 6 months<br />
– Centralized, broth enriched culture used for testing<br />
• Incidence of colonization or infection with MRSA or<br />
VRE per 1000 patient-days at risk did not differ<br />
significantly (P = 0.35)<br />
• Mean (±SD) number of days from when surveillance<br />
swab obtained until it was reported was 5.2±1.4<br />
– 41% of patient days captured after reporting<br />
