Population Description

Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
'Number of Participant' totals reflect total Baseline and Intervention participants combined. 45 hospitals were randomized to a study group, 2 dropped due to exclusion criteria, 43 began the assigned intervention. 1 hospital withdrew during the intervention and was included in as-assigned analyses.

Reporting Groups

	Description
Arm 1: Usual Care-Active Surveillance	Active Surveillance in All Adult ICUs, Contact Precautions for MRSA+
Arm 2: Targeted Decolonization	Continue Active Surveillance (AS), MRSA decolonization based on AS, Continue Contact Precautions for MRSA+ Chlorhexidine bath and nasal mupirocin: The intervention / decolonization regimen will consist of the most commonly used topical regimen in the US – a combination of daily baths with 2% chlorhexidine cloths plus 5 days of topical intranasal mupirocin ointment (bilateral nares, twice daily)
Arm 3: Universal Decolonization	Chlorhexidine bath and nasal mupirocin for all, Discontinuation of Active Surveillance, Contact Precautions for MRSA+ Chlorhexidine bath and nasal mupirocin: The intervention / decolonization regimen will consist of the most commonly used topical regimen in the US – a combination of daily baths with 2% chlorhexidine cloths plus 5 days of topical intranasal mupirocin ointment (bilateral nares, twice daily)

Outcome Measures

Show All Outcome Measures

1. Primary:

Main Outcome: Patients With Nosocomial MRSA Clinical Cultures [ Time Frame: The 30-month time frame represents 12-month baseline and 18-month intervention periods. During these time periods, outcomes are defined as events occurring during attributed ICU time: from day 3 of the ICU stay until 2 days after ICU discharge. ]

Show Outcome Measure 1

2. Secondary:

MRSA Bloodstream Infection [ Time Frame: The 30-month time frame represents 12-month baseline and 18-month intervention periods. During these time periods, outcomes are defined as events occurring during attributed ICU time: from day 3 of the ICU stay until 2 days after ICU discharge. ]

Show Outcome Measure 2

3. Secondary:

ICU-attributable All-pathogen Bloodstream Infection [ Time Frame: The 30-month time frame represents 12-month baseline and 18-month intervention periods. During these time periods, outcomes are defined as events occurring during attributed ICU time: from day 3 of the ICU stay until 2 days after ICU discharge. ]
