Diagnostic assessment of different environmental cleaning monitoring methods.
In a simultaneous assessment of 250 environmental surfaces after terminal cleaning using aerobic cultures as a gold standard, both fluorescent marker and an adenosine triphosphate bioluminescence assay system demonstrated better diagnosticity compared with subjective visual inspection. These results support the use of these environmental monitoring systems in the health care setting.

Effect of central line bundle on central line-associated bloodstream infections in intensive care units.
This study was conducted in 4 intensive care units (ICUs) to investigate the effect of the central line (CL) bundle on central line-associated bloodstream infection (CLABSI). ⋯ The higher adherence to the CL bundle was not positively correlated to a reduction in the CLABSI rate in adults, but it was related to a zero CLABSI for 18 months among children in the ICUs.

Disinfection of needleless connectors with chlorhexidine-alcohol provides long-lasting residual disinfectant activity.
The optimal disinfection method for needleless connectors (NCs) is unclear. We used an experimental model of microbial NC contamination to test different scrub times (swipe, 5, 15, 30 seconds) of chlorhexidine-alcohol versus alcohol and for residual disinfectant activity. Swipe with alcohol did not adequately disinfect NCs, particularly when contaminated with Staphylococcus aureus or Pseudomonas aeruginosa. With ≥5-second scrub, chlorhexidine-alcohol and alcohol performed similarly, but chlorhexidine-alcohol showed residual disinfectant activity for up to 24 hours.
