Abstract

OBJECTIVE: To test whether a critical care consult team can be used to identify patients who have methicillin-resistant Staphylococcus aureus nasal colonization during a window period at which they are at highest risk for methicillin-resistant S. aureus infection and can most benefit from topical decolonization strategies. DESIGN: Prospective cohort study. SETTING: Two adult tertiary care hospitals. PATIENTS: Patients with at least one risk factor for methicillin-resistant S. aureus nasal colonization who were seen by a critical care consult team for potential intensive care unit admission were enrolled. INTERVENTIONS: Nasal cultures for methicillin-resistant S. aureus were performed on all subjects. All subjects were followed for the development of a methicillin-resistant S. aureus infection for 60 days or until hospital discharge. Demographic and outcome data were recorded on all subjects. MEASUREMENTS AND MAIN RESULTS: Two hundred subjects were enrolled. Overall 29 of 200 (14.5%) were found to have methicillin-resistant S. aureus nasal colonization. Methicillin-resistant S. aureus infections occurred in seven of 29 (24.1%) subjects with methicillin-resistant S. aureus nasal colonization vs. one of 171 (0.6%) subjects without methicillin-resistant S. aureus nasal colonization (p <.001). Methicillin-resistant S. aureus clinical specimens were recovered in 15 of 29 (51.7%) subjects with methicillin-resistant S. aureus nasal colonization vs. two of 171 (1.2%) without methicillin-resistant S. aureus nasal colonization. CONCLUSIONS: A critical care consult team can be used to rapidly recognize patients with methicillin-resistant S. aureus nasal colonization who are at very elevated risk for methicillin-resistant S. aureus infection. The use of such a team to recognize patients who have greatest potential benefit from decolonization techniques might reduce the burden of severe methicillin-resistant S. aureus infections.
