What researchers measure

Primary outcomes

  1. Number of Participants With Combination of Gastrointestinal Tract Colonization With Multi-drug Resistant Gram-negative Bacteria, C. Difficile and VRE

    Colonization of the gastrointestinal tract with C. difficile, vancomycin-resistant enterococci, multidrug-resistant Acinetobacter baumannii, and multidrug- resistant Pseudomonas. Colonization occurs when the subject acquires the above organism while in the study.

    Time frame: Participants will be followed while Intubated, an expected average of 7 days. The outcome will be measured 3 days after enrollment and at the end of intubation, average time 7 days)
