The IVCare Adaptive Platform Trial
Comparative Effectiveness of Interventions to Prevent Infections and Other Complications Arising From Central Venous Access Devices: the IVCare Adaptive Platform Trial.
The IVCare trial is a multicentre adaptive platform study evaluating interventions to prevent infections and other complications associated with central venous access devices (CVADs) in patients with newly inserted or existing devices. The study is organised into domains addressing different aspects of CVAD care and includes patient groups referred to as strata. Domains, strata and interventions may change over time as the study progresses. IVCare also includes an observational cohort study in which patients with CVADs are followed to assess CVAD care practices, infections, and other CVAD-related complications across health services.
The trial starts with two domains. The Connectors/Caps Domain compares antimicrobial connectors and caps with standard-of-care connectors and caps used in Australian hospitals. In the cancer stratum, participants are randomised to receive either Curos™ or standard-of-care connectors/caps. In the kidney disease stratum, participants are randomised to receive either ClearGuard™ HD or standard-of-care connectors/caps. Following a predefined stopping decision for ClearGuard™ HD in the kidney disease stratum, Tego™ will be introduced and evaluated in this group.
The Securement Domain compares the effectiveness of SecurAcath®, a subcutaneous anchor securement system, with standard-of-care securement methods used in Australian hospitals. Participants in both the cancer and kidney disease strata are randomised to receive either SecurAcath® or standard-of-care securement.

详细说明
Participants who have or require a CVAD, including a peripherally inserted central catheter (PICC), non-tunnelled or tunnelled central venous catheter (CVC), or totally implanted venous access port, are eligible for the IVCare trial.
Participation in the observational cohort is a core component of trial participation and occurs for all enrolled participants. Participation in intervention domains is optional. Participants may be enrolled in more than one intervention domain concurrently.
Each domain has its own inclusion and exclusion criteria in addition to core eligibility requirements. Participants will be followed for up to 180 days from enrolment into the observational cohort or randomisation to one or more interventions.
Participants who complete follow-up in the observational cohort and/or one or more intervention domains may be eligible for re-entry, provided they meet eligibility criteria.
There is no fixed sample size for this adaptive platform trial. Recruitment into each domain will be guided by pre-specified interim analyses of accumulating data using Bayesian methods. Predefined decision rules will determine adaptations, including early stopping for futility, non-inferiority, or superiority of interventions within each domain.

干预/治疗 |
|---|---|
|
有源比较器：Connectors/Caps Domain - Standard of care
|
Any needle-free or closed-system connector or cap that does not contain antimicrobial agents and does not incorporate specific infection-prevention design features.
|
|
实验性的：Connectors/Caps Domain - ClearGuard™ HD for the kidney stratum
|
The ClearGuard™ HD cap is designed for use with haemodialysis catheters.
It attaches to compatible catheter hubs to maintain a closed system between dialysis sessions.
The cap is coated with chlorhexidine, which is intended to reduce microbial colonisation at the catheter hub interface.
|
|
实验性的：Connectors/Caps Domain - Tego™ for the kidney stratum
|
Tego™ is a needle-free capping device that closes the end of a catheter, creating a mechanically and microbiologically closed system when attached to the catheter hub.
|
|
有源比较器：Securement Domain - Standard of care
|
Basic securement using sterile tape/adhesion fixation device and a simple transparent dressing, without antimicrobial, antiseptic, or engineered stabilization features.
|
|
实验性的：Securement Domain - SecurAcath®
|
SecurAcath® is a subcutaneous catheter securement system.
The device utilises a small anchor (securement feet) placed just beneath the skin at the catheter insertion site and then attached to the catheter shaft.
It mechanically stabilises the catheter, reducing movement and migration.
|
|
实验性的：Connectors/Caps Domain - Curos™ for the cancer stratum
|
Curos™ is a passive disinfecting cap intended for use with needleless connectors The cap contains 70% isopropyl alcohol.
Its intended mechanism of action is to provide continuous antimicrobial protection of the connector surface between line accesses and act as a physical barrier to contamination, thereby reducing the potential for microbial transmission through the catheter hub
