Chlorhexidine-Alcohol Versus Povidone Iodine-Alcohol, Combined or Not With Use of a Bundle of New Devices, for Prevention of Intravascular-catheter Colonization and Catheter Failure

• Status: Completed
• Trial end date: 2019-09-27
• Target enrollment: 0
• Participant gender: All

Summary

Short peripheral intravenous catheters (PVC) are the most frequently used invasive medical devices in hospitals. Unfortunately, PVCs often fail before the end of treatment due to the occurrence of complications, which can be mechanical, vascular or infectious. Complications lead to infusion failure and device replacement, which results in interrupted therapy, pain associated with resiting and increased health care costs for resources and staff time. Catheter related bloodstream infections (CR-BSIs) prolong hospitalization and increase treatment costs and mortality.

Prevention of these complications is based on the respect of hygiene rules and the use of bio-compatible catheters. The choice of the antiseptic solution for skin disinfection is key. Similarly, the use of new technologies such as catheters designed to minimize blood exposure, zero-reflux needleless-connectors, disinfecting caps, and flushing PVCs before and after each medication administration to maintain catheter patency are of theoretical interest, but little scientific data support their use in routine.

The primary objectives of this study are, first, to demonstrate that skin preparation with 2% chlorhexidine (CHG)-70% isopropanol decreases the risk of PVC colonization compared to skin preparation with 5% povidone iodine (PVI)-69% ethanol. Second, to demonstrate that use of a bundle of technologies including a new PVC, zero-reflux needless-connectors, disinfecting caps, and single-use prefilled flush syringes extends the time between catheter insertion and catheter failure.

The secondary objectives are to compare between the four study group incidence of phlebitis, accidental catheter removal, infiltration, catheter occlusion, CR-BSI, local infection, all-cause bloodstream infections, catheter colonization, duration of catheter remaining in place without complication, length of hospital stay, safety and patient satisfaction.

The CLEAN 3 study is an open-label, single centre, investigator-initiated, randomised, four-parallel group, two-by-two factorial trial. Patients requiring PVC for an expected 48 h will be randomised in one of four groups according to skin disinfection method and type of devices used. Randomization will be carried out through a secure web-based randomization system. Inclusions are expected to begin in January 2019 and continue until July 2019, once the number of catheters required has been reached.

Patients will be enrolled at the Emergency department of the Poitiers University Hospital before being hospitalised in one of five wards (neurology, neurology, pneumology, internal medicine and downstream emergency unit).
