Why
  1. The study's listed conditions name Bacteremia, a narrower term within Infections.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

Intravenous catheters are often placed in large (central) veins in critically ill patients to provide special medications or frequent blood sampling. The body reacts to the presence of foreign material by forming a biofilm on the surface within the catheter. Either due to the patients condition or to emergency access to these intravenous lines can become infected with bacteria and reside within the biofilm. When bacteria is grown from these lines it is referred to as: a central line infection. A medical device company (ICU Medical) has obtained the rights to a device that delivers a controlled amount of a cleaning material called chlorhexidine into the catheter to prevent bacterial growth when not in use. Chlorhexidine is the standard cleaning material used on patients when cleaning the skin for surgical procedures or central intravenous catheter insertion. In laboratory tests and animal studies that chlorhexidine inhibits the growth of bacteria and fungi that often cause central line infections. This study will the first assessment in patients with central lines.

Read the detailed description

Randomization Randomization will be determined using an online random number generator. "www.randomize.net". The research coordinator will randomize the patients and provide bedside staff with the devices when appropriate.

Intervention

Eligible patients that have provided informed consent will be randomized to receive:

  1. Steril-flow® (CHG-Lock™) device OR
  2. Usual care

Test Protocol

  1. For patients randomized to the CHG-LockTM device, attach a attach a BD Posiflush ™ 0.9% Sodium Chloride (Na Cl) 10ml syringe and a CHG-Lock™ device for each IV line that is to be locked. Follow hospital approved protocol for flush, volumes and hand hygiene (see appendix I, II and III).

    After a Catheter has been locked, before re-accessing the catheter for further sampling or infusions, all fluid should be aspirated from the catheter to clear the device of CHG, Heparin and the like. This should also confirm patency of the device.

  2. Discard the syringe and device in biohazard waste.
  3. "Blue Cap" the IV as per routine practice.

    • There is no need to use the CHG-Lock™ device for IV lines with IV solutions infusing or those attached to an IV pressure bag, to maintain IV patency.
    • If the Central Line IV is blocked, access is done by withdraw 2-3 ml discard of blood, flush with 20 mls.
    • If a line is blocked, do not force, the order must be obtained for Cathflo and administered by a certified Cathflo nurse.
    • A CHG-Lock™ device will be applied with every intravenous flush for patients in the Active (CHG-LockTM ) arm.
    • Bedside nurses will be educated on the use of the CHG-Lock™ device.
    • The device will be used for every central line and peripheral IV instillation.
    • All locking solutions must be removed prior to access. This is standard of practice.
    • Bedside nurses will be asked to document application of the device and instillation in the medication profile.
    • Pre-printed Physician Order Set will be created to ensure compliance with device use and protocol.
    • A box with devices will be placed at the bedside to ensure ease of access for nurses and that patients receive the device at every lock episode.

Duration of intervention:

  • The intervention will be used while the central line or peripheral IV remains in situ.
  • The intervention will be discontinued when the patient leaves the ICU or the IV is discontinued.

Measures to be taken to ensure compliance:

  1. Study boxes labeled with patient name and ID at the bedside.
  2. Staff education (see 3.13)
  3. Daily oversight by research coordinator/Assistant

Study arms

  • Experimental
    Antiseptic device

    Patients who are randomized to receive the device will receive Chlorhexidine at a dose of 0.24-0.42 mg/installation into all intravenous lines. The intervention will be administered every 24 hrs and as needed for as long as the intravenous is in place

    Device: Chlorhexidine flush

  • No intervention
    Routine Care

    Patients who are randomized to routine care (no device, no intervention) will receive normal saline flush as per standard ICU care.

Interventions

  • DeviceChlorhexidine flush

    1. For patients randomized to the CHG-LockTM device, attach a attach a BD Posiflush ™ 0.9% Sodium Chloride (Na Cl) 10ml syringe and a CHG-Lock™ device for each IV line that is to be locked.

What researchers measure

Primary outcomes

  1. Compliance with the protocol

    The investigators will consider our study successful if we achieve compliance of than 90% use of device for locking.

    Time frame: Through study completion, an average of 14 days

Secondary outcomes

  1. Bacteremia

    Rates of bacteremia determined by blood cultures obtained through a central line

    Time frame: Through study completion, an average of 14 days

  2. Bacteria colonization of central line

    Central Line Colonization Testing will be completed when the investigators are able to obtain the discontinued central line catheters for Electron Microscopy examination

    Time frame: Through study completion, an average of 14 days

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2017 to primary completion in Nov 2020, 36 months.

Of 34 non-industry interventional studies with no phase under Bacteremia, half reached primary completion within 34 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 64. This study's 36 months is close to that.

Counting every sponsor, half of 35 studies reached it within 34 months; a quarter within 13 and three quarters within 64.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 5, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
