Brief summary

In the intensive care unit, patients' care and secure drugs administration require a central venous catheter. These invasive devices can lead to complications, particularly infections. Most preventive recommendations focus on catheter insertion, line handling, and dressings. Few recommendations adress catheter dwell time, which is certainly the main source of infection. Part of the prevention strategy is the regular and systematic replacement of infusion sets , as they may become contaminated during use, mainly through the hands of healthcare professionals. Prolonged use increases the risk of infection. Infusion lines changes involve disconnecting the old sets, discarding infusion devices containing drug residues, and replacing them with new sterile devices. Current international guidelines recommend replacing these sets every 4 days, and the Center for Disease Control and Prevention recommends not exceeding 7 days. Replacing these devices requires the time of qualified nurses, numerous sterile medical devices, and medications. In addition to the intended effect on infection prevention, the procedure has impacts on workload and costs. The objective of the study is to demonstrate that changing infusion set every 7 days does not increase the rate of central venous catheters related infections compared with changing infusion set every 4 days.

Interventions

PROCEDURE7-day Infusion set replacement

7-day infusion set replacement (Experimental arm) In this group, the infusion sets (the tubes and connectors used to deliver medications through the central venous catheter) will be changed once a week, every 7 days. During each replacement, all sets will be disconnected and replaced with new sterile ones.

PROCEDURE4-day infusion set replacement

4-day infusion set replacement (Active comparator arm) In this group, the infusion sets will be changed every 4 days, which reflects the most common international recommendation. The procedure is the same: all sets connected to the central venous catheter will be replaced with new sterile ones. This strategy represents the current standard of care and will serve as the comparison for the 7-day approach.

Inclusion criteria

* Adult patient * Any ICU patient with a central venous catheter (inserted by venipuncture) in place for less than 72 hours and with an expected dwell time of at least 7 days * Patient affiliated with or covered by a social security system * Patient who has given verbal consent or written consent from a third party or in the event that the patient is unable to give consent.

Exclusion criteria

* Patient with a documented bloodstream infection at the time of inclusion * Patient whose central venous catheter has been in place for more than 72 hours * Patient with suspected catheter-related infection * Patient whose study catheter was inserted using a guidewire exchange * Patient previously enrolled in the study during the same ICU stay * Patient whose condition, according to the clinician, does not allow safe placement of a central venous catheter, such as: * Allergy to catheter material * Confirmed deep vein thrombosis at the time of insertion * Inflammatory skin disorder at the insertion site * Patient admitted for extensive burns * Inadequate understanding of the French language * Pregnant, breastfeeding, or postpartum woman * Person deprived of liberty by judicial or administrative decision * Person receiving involuntary psychiatric care * Person under legal guardianship or other legal protection measure

Design outcomes

Primary

MeasureTime frameDescription
Rate (%) of patients with with a central venous catheter-related infectious complicationFrom central venous catheter insertion until 48 hours after catheter removal during the ICU stay (censored at 90 days).Infectious complications include: 1. Catheter-related infections (CRI) defined as: * A positive catheter culture, with quantitative culture ≥10³ CFU/ml (Brun-Buisson technique) or, if not available, a semi-quantitative culture \>15 CFU (Maki technique), and purulence at the catheter insertion site or tunnelitis. Or * A positive catheter culture, with quantitative culture ≥10³ CFU/ml (or semi-quantitative culture \>15 CFU), and complete or partial regression of systemic signs of infection within 48 hours after catheter removal. 2. Catheter-related bloodstream infections (bacteremia or fungemia) defined as: * The occurrence of bacteremia (or fungemia) within 48 hours before or after catheter removal (or suspected catheter-related infection if the catheter is not immediately removed), And * Either a positive culture with the same microorganism from the insertion site or catheter, with ≥10³ CFU/ml (Brun-Buisson technique) or, if not available, a semi-quantitative culture
