Abstract Background There is an increasing use of daily chlorhexidine gluconate (CHG) bathing to decrease healthcare associated infections (HAI). Daily bathing of patients with CHG has been successfully used to prevent multidrug-resistant organisms (MDROs) HAI in intensive care units (ICU). Methods This was a 12-month, single-center, open, cluster randomized trial, conducted at four ICUs of the University Hospital of Universidade Federal de São Paulo, Unifesp, Brazil. ICUs were randomized to either perform daily bathing of the patients with pH neutral soap and water – control units, or daily bathing with 2% CHG detergent solution – intervention units. We evaluated the incidence density rate of central line-associated bloodstream infection (CLABSI), ventilator-associated pneumonia (VAP), catheter associated urinary tract infection (CAUTI), Klebsiella pneumoniae carbapenemase (KPC)-producing enterobacteria HAI, and death in the intervention and control units. Results A total of 1,640 admissions of 1,487 patients occurred during the study period (41.2% control group, and 58.8% intervention group). Incidence density rates of KPC-producing enterobacteria HAI were 5.01 and 2.25 infections/1000 patient-days in the control units and in the intervention units (p = 0.013) and mortality rates were 28.7% and 18.7% in the control units and in the intervention units (p<0.001), respectively. No difference between groups was observed in CLABSI incidence (p = 0.125), VAP incidence (p = 0.247) and CAUTI incidence (p = 0.435). No serious skin reactions were noted in either study group. Daily 2% CHG detergent solution bathing is a feasible, low cost option for HAI prevention in ICU.
