Brief 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).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of catheter-related infectious complications | 8 days | Incidence of catheter-related infectious complications, and include catheter colonisation, local infection and CR-BSI |
| Time between catheter insertion and catheter failure | 8 days | Time between catheter insertion and catheter failure: defined as any premature removal of PVC before end of treatment, other than for routine replacement, and includes phlebitis, infiltration, occlusion, accidental catheter removal, local infection and CR-BSI whichever occurred first |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of infiltration | 8 days | Number of infiltration, defined as the infusion of non-blistering drug leaking through the normal vascular channel and resulting in the swelling of tissue peripheral to the puncture site |
| Number of catheter occlusion | 8 days | Number of catheter occlusion defined as the inability of the catheter to flush (not able to intravenously inject 1ml of normal saline within 30 s) |
| Number of CR-BSI | 8 days | Number of CR-BSI, defined as (1) at least one positive blood culture from a peripheral vein and (2) clinical signs of infection (ie, fever \[body temperature \>38°5\], hypothermia \[body temperature \<36°5\], chills, or hypotension \[Systolic blood pressure \<90 mm Hg\]) and (3) no other apparent source for the bloodstream infection except the PVC (in situ within 48 h of the bloodstream infection); and (4) a colonized intravenous catheter tip culture with the same organism (same species) as identified in the blood. For commensal micro-organisms (coagulase-negative staphylococci, Corynebacterium spp. \[except C. jeikeium\], Lactobacillus spp., Bacillus spp. and Propionibacterium spp., or viridans group Streptococcus isolates and C. perfringens) at least two positive blood cultures will be required. |
