Study summary

The Swap Out Trial is a cluster randomized controlled trial of HCA hospitals, evaluating the non-inferiority of two decolonization regimens:

Arm 1 Routine Care: ICU nasal decolonization with mupirocin twice daily for 5 days in the context of chlorhexidine for daily bathing; Arm 2 Intervention: ICU nasal decolonization with iodophor twice daily for 5 days in the context of chlorhexidine for daily bathing Note: that enrolled "subjects" represents 137 individual HCA Hospitals (representing \~235 ICUs) that have been randomized.

Interventions

  • DrugArm 1. Routine Care (Mupirocin/CHG)

    The intervention / decolonization regimen will consist of 5 days of topical intranasal mupirocin ointment (bilateral nares, twice daily) on ICU admission, in the context of continued daily baths with 2% chlorhexidine cloths.

  • DrugArm 2. Iodophor/CHG Decolonization

    The intervention / decolonization regimen will consist of 5 days of topical intranasal iodophor (10% povidone-iodine nasal swabs) (bilateral nares, twice daily) on ICU admission, in the context of continued daily baths with 2% chlorhexidine cloths.

What researchers measure

Primary outcomes

  1. Number of Participants With ICU-attributable Staphylococcus Aureus Clinical Cultures

    Methicillin-resistant Staphylococcus aureus (MRSA) and Methicillin-susceptible Staphylococcus aureus (MSSA) clinical cultures attributable to participating ICUs. Defined as occurring \>2 days into a participating ICU stay through 2 days following ICU discharge. NOTE: this outcome is intended for the primary manuscript.

    Time frame: 18-month intervention

Secondary outcomes

  1. Number of Participants With ICU Attributable MRSA Clinical Cultures

    Methicillin-resistant Staphylococcus aureus (MRSA) clinical cultures attributable to participating ICUs. Defined as occurring \>2 days into a participating ICU stay through 2 days following ICU discharge. NOTE: this outcome is intended for the primary manuscript.

    Time frame: 18-month intervention

  2. Number of Participants With ICU-attributable Bloodstream Infections

    All-cause bloodstream infection attributable to participating ICUs. Defined as occurring \>2 days into a participating ICU stay through 2 days following ICU discharge.Includes subsets of gram positive (GP), gram negative (GN) and fungal (candida) bloodstream infections, as well as key pathogens such as S. aureus (MRSA and MSSA). NOTE: this outcome is intended for the primary manuscript.
