*All multivariable logistic regression models were adjusted for total number of adult acute care or ICU beds, medical school affiliation, involvement in HAI collaborative, overall support for infection control programme from hospital leadership, presence of a hospital epidemiologist and whether the lead infection preventionist is certified in infection control. Other domain-specific independent variables (eg, perception of how important it is to hospital leadership to prevent CAUTI, CLABSI or VAP, and various CAUTI, CLABSI and VAP surveillance measures) were included within multivariable models if significant in bivariable analyses.
†Sample sizes for CAUTI prevention practices were as follows: portable bladder ultrasound=476, urinary catheter reminder/stop order and/or nurse-initiated catheter discontinuation=469, silver alloy catheters=467, condom catheters in men=465, aseptic technique during catheter insertion and maintenance=469, intermittent catheterisation=469.
‡Sample sizes for CLABSI prevention practices were as follows: maximum sterile barrier precautions during central catheter insertion=476, antimicrobial catheters=466, antimicrobial dressing with chlorhexidine=481, use of midline catheters instead of central venous catheters=473.
§Sample sizes for VAP prevention practices were as follows: antimicrobial mouth rinse=449, ‘Sedation vacation’=449, subglottic secretion drainage=431, topical and/or systemic antibiotics for selective digestive tract decontamination=433, silver-coated endotracheal tubes=427.
