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.
