Description

Up to 70% of patients in acute care hospitals need a central venous access, and the latter is also widely used in other clinical settings. However, the central venous access usually remains associated with increased infection risks, which can be severe and even lethal.

Most contemporary guidelines recommend infusion set replacement every 4 days with the CDC in US recommending replacement "no more frequently than 96 hours, but at least every 7 days". However, the National Health Commission of the People's Republic of China recommend infusion set replacement every 24 hours in 2021. The previous evidence from neonate were in favor of the administration set changes of every 24 hours, compared with the longer time interval. However, it is unclear whether this conclusion applied to adult critically ill patients in ICU.

The purpose of the current study is therefore to compare the effectiveness of 24-hour versus 96-hours infusion set replacement to prevent central line-associated bloodstream infection (CLABSI) in critically ill adults with central venous access devices.

This study is a multicenter, single-blind randomized clinical trial designed to investigate the efficacy of the 24-hour versus 96-hours infusion set replacement to prevent central line-associated bloodstream infection (CLABSI) in critically ill adults with central venous access devices. The trial will enroll up to 1240 participant. The primary endpoint for this trial is the CLABSI rate. Mortality rate is a key secondary endpoint for the trial.

Specific Aims

1. To demonstrate the efficacy of 24-hour infusion set replacement to reduce the rate of CLABSI, compared with 96-hours infusion set replacement.
2. To demonstrate the efficacy of 24-hour infusion set replacement to reduce the rate of CRBSI, all-cause bloodstream infection, and mortality, compared with 96-hours infusion set replacement.
