Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Stepped cluster wedge randomised implementation project
The Project will be carried out in 4 phases:
Phase I: Study site set up Dec 2015-Aug 2016
Phase II: Baseline data collection Dec 2016-ongoing
Phase III: Implementation (stepped wedge randomisation) April 2018-sept 2019
Phase IV: Post implementation data collection phase Sep 2019-Aug 2020

The individual components of the intervention are broken into three milestones in catheter use:
1. Interventions employed at the time of dialysis catheter insertion such as in operating theatres/radiology/renal units/ICU:
a. Ensuring hand hygiene at the time of catheter insertion
b. Use of full barrier protection at insertion
c. Cleansing of the insertion site with antiseptic solution
d. Avoidance of the femoral site for catheter insertion
e. Preference given to the use of subcutaneously tunnelled catheters
2. Interventions employed during the dialysis catheter maintenance phase by nursing staff on dialysis wards:
a. Use of a standardised catheter insertion site dressing technique using topical antimicrobial preparations (+/- intraluminal catheter locks/topical antimicrobial preparations) and standardised frequency of dressing change
b. Provision of standardised nurse-delivered training to patients and their caregivers on the importance of catheter care, along with provision of a patient information sheet on dialysis catheter care
c. Protocol driven training in the aseptic techniques for connection and disconnection of the catheter for each haemodialysis treatment
d. Training and provision of education materials to patients that enhance their skills in managing dialysis catheters
3. Interventions associated with dialysis catheter removal on dialysis wards by nursing and medical staff:
a. Ensure the timely removal of catheters when no longer required

The Interventions have now been finalised, but have not been broadly publicised. The final tranche of sites have implemented the interventions. We will be publishing the interventions in the next 6 months.

Treatment: Other
Comparator / control treatment
This is a stepped cluster wedge randomised implementation project. All sites in the study will function as a control group before they are randomized to receive the suite of interventions. All sites will receive the interventions as part of the implementation phase.
Participating Renal Units will continue their current processes of care around dialysis catheter insertion and management until they are randomised during the implementation phase. This will be governed by existing hospital policies and procedures.
Control group
Active

Outcomes
Primary outcome [1] 298670 0
Rate of dialysis catheter related bacteraemia.
The endpoint will be determined by review of routine hospital laboratory tests performed on the participants (blood, catheter tip, swab cultures)
Dialysis catheter related bacteraemia is defined as meeting one of the following criteria:
*Culture of the same organism from both the catheter tip and at least one percutaneous blood culture.
*Culture of the same organism from at least two blood samples (one from a catheter hub and the other from a peripheral vein or second lumen) meeting criteria for quantitative blood cultures or differential time to positivity.
*Bacteraemia in the absence of another source
*Rate unit is measured per 1000 catheter days.
Timepoint [1] 298670 0
Outcomes will be assessed 2 weeks post catheter line removal for each participant to enable all test results to be collected.
Secondary outcome [1] 324910 0
Suspected or probable catheter related bacteraemia defined as catheter removal for the reason of suspected infection with negative blood cultures
Timepoint [1] 324910 0
2 weeks post catheter removal
Secondary outcome [2] 324979 0
Determination of the burden of exposure to central venous dialysis catheters
The burden of exposure will be measured using line days and bacteraemia rates.
Dialysis catheter related bacteraemia is defined as meeting one of the following criteria:
*Culture of the same organism from both the catheter tip and at least one percutaneous blood culture.
*Culture of the same organism from at least two blood samples (one from a catheter hub and the other from a peripheral vein or second lumen) meeting criteria for quantitative blood cultures or differential time to positivity.
*Bacteraemia in the absence of another source
Timepoint [2] 324979 0
2 weeks post catheter removal
Secondary outcome [3] 324981 0
Determination of Economic burden that arises from dialysis catheter exposure and infection and the economic case for investing in the multi-faceted intervenions.
This will be determined through state-specific linkage to hospitalisation and death datasets and this aspect of the study will be finalised once the data linkage component is finalised.
Timepoint [3] 324981 0
Outcomes will be collected and assessed once data linkage is performed on state hospitalisation, mortality and morbidity data.
Data linkage is intended to be performed once at the end of the study.

Eligibility
Key inclusion criteria

*Initiation of maintenance haemodialysis
*Provision of acute haemodialysis for acute kidney injury (where the care of the dialysis catheter is under the auspices of the participating renal unit)
*Interim haemodialysis due to failure of an existing dialysis access (e.g.: failure of peritoneal dialysis, thrombosis of an existing arterio-venous fistula).
Minimum age
18 Years
Maximum age
No limit

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
No allocation concealment
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The REDUCCTION Project will randomise the study intervention at the unit, rather than the patient, level. The suite of interventions will be rolled out in three successive tranches.

The timing of the implementation of the suite of interventions will be randomised at a unit level using a sequence generated by the Statistics Division, within The George Institute for Global Health (TGI). The Study staff at TGI will then communicate this to the primary contact person at the individual sites.
Masking / blinding

Intervention assignment
Other
Other design features
Stepped Wedge Cluster Randomised trial. All units will be randomised to receive the intervention and the random factor is the timing of randomisation.
There will be 3 successive tranches of site randomisation over a 12 month period, whereby approximately 10 sites at each time-point will be allocated to the study intervention suite.

Type of endpoint/s
Statistical methods / analysis
A formal statistical analysis plan will be derived for the study prior to analysis and publication of study results. The expected baseline rate of dialysis catheter related bacteraemia is 2.5 per 1000 catheter days, derived from Concord data and the published literature and the number of intervention points (n of steps) planned is 3. The powering is based upon the intervention resulting in a 50% reduction in the risk of catheter related bacteraemia. An additional consideration is the inter-cluster correlation co-efficient (ICC) which is conservatively estimated at 0.07 (this study design is robust to an increase in ICC), when the rate seen in a large US study from 2014 was 0.03. On the basis of these figures, the project has a power of over 0.9 to detect a 50% reduction in the bacteraemia rate using a proposed sample of 30 Renal units following 100 patients per ‘step’ in the stepped-wedge design. This is likely a conservative figure as the ICC in other studies has been substantially lower and the number of patients per step is likely to be more than 100 as the duration of follow up post intervention is longer for some units.
