Abstract

Background Patients with hemodialysis central venous catheters (HD CVC) are susceptible to health care associated infections, particularly hemodialysis catheter related blood stream infection (HD-CRBSI), which is associated with high mortality and health care costs. There have been few systematic attempts to reduce this burden and clinical practice remains highly variable. This manuscript will summarize the challenges in preventing HD-CRBSI and describe the methodology of the REDUcing the burden of dialysis Catheter ComplicaTIOns – a National approach (REDUCCTION) trial.

Methods The REDUCCTION trial is a stepped wedge cluster randomized trial of a suite of clinical interventions aimed at reducing HD-CRBSI across Australia. It clusters the intervention at the renal service level with implementation randomly timed across three tranches. The primary outcome is the effect of this intervention upon the rate of HD-CRBSI.

Patients who received a HD CVC at a participating renal service are eligible for inclusion. A customized data collection tool allows near to real-time reporting of the number of active catheters, total exposure to catheters over time and rates of HD-CRBSI in each service.

The interventions are centered around the insertion, maintenance and removal of HD CVC, informed by the most current evidence at the time of design (mid-2018).

Results A total of 37 renal services are participating in the trial. Data collection is ongoing with results expected in the last quarter of 2020. The baseline phase of the study has collected provisional data on 5385 catheters in 3615 participants, representing 603,506 days of HD CVC exposure.

Conclusion The REDUCCTION trial systematically measures the use of HD CVCs at a national level in Australia, accurately determines the rate of HD-CRBSI and tests the effect of a multifaceted, evidence-based intervention upon the rate of HD-CRBSI. These results will have global relevance in nephrology and other specialties commonly using CVCs.

Introduction

Patients receiving hemodialysis are highly susceptible to healthcare-associated infections. Most prominent among these infections is hemodialysis catheter-related bacteremia (HD-CRBSI), which is associated with high mortality and high health care costs.(1) Hemodialysis central venous catheters (HD CVC) are ubiquitous in modern nephrology; used in up to 80% of incident maintenance hemodialysis patients, 20% of prevalent hemodialysis patients and universally in patients requiring hemodialysis for acute kidney injury.(2-5)

HD-CRBSI is associated with risks beyond the primary event, such as endocarditis, major organ abscesses, recurrent sepsis and mortality. A 2013 meta-analysis concluded that the healthcare cost per episode of all CVC-related bacteremia, including HD-CRBSI, in the USA was $45,814 (95% CI $30,919- $65,245), constituting 18.9% of the total national cost of healthcare-associated infections or $1.85b per annum.(1) These costs exclude the impact on the patient’s quality of life from additional catheters, hospital admissions and medical procedures.

There have been few systematic attempts to reduce this burden in dialysis services, and clinical practice remains highly variable.(6) Many interventions have been studied with the aim of reducing HD-CRBSI, and the nature of this literature has likely contributed to practice variation.(6-9) The recent Making Dialysis Safer for Patients Coalition initiative, led by the Centers for Disease Control and Prevention (CDC), is testament to the need for standardized approaches to infection prevention in dialysis services as was the success of the Keystone Michigan Project.(10, 11) Herein, we review the research that formed the basis of the design and protocol of the REDUcing the burden of dialysis Catheter ComplicaTIOns – a National approach (REDUCCTION) trial, a stepped-wedge cluster randomized clinical trial of a suite of clinical interventions aimed at reducing the rate of HD-CRBSI across Australian renal services.

Challenges in reducing HD-CRBSI

1. Reporting and comparison of rates of HD-CRBSI A crucial requirement for the implementation and evaluation of strategies to reduce HD- CRBSI is the ability to accurately measure and report the disease burden. While measurement has been done well in RCTs and prospective studies, sustainable, system-wide measurement in clinical practice can be difficult. Historically, HD-CRBSI rates have used different definitions and denominators, with the numerator usually being HD-CRBSI events and denominators using variable measures of catheter exposure, making comparisons difficult.(12, 13) Furthermore, the lack of clinical adjudication of BSI also adds uncertainty around the true rate of HD-CVC BSI. Our survey of ANZ renal services found 84% of services were collecting data on HD-CRBSI rates but only 51% could report a rate.(6) The reported HD-CRBSI rates in the literature vary widely, with published rates of 1.1 - 5.5 episodes per 1000 days of catheter exposure at the time of design of the REDUCCTION trial.(14-17) Studies published from USA and Canada subsequently have published much lower rates of between 0.19-0.84 per 1000 catheter days, making it difficult for clinicians to ascertain appropriate targets.(13, 18) 4

2. Complex care There are many components to catheter care, with breakdown in any element likely to influence the risk of HD-CRBSI. Published research has focused upon the use of prophylactic antimicrobial agents, either applied topically to the catheter exit site, or as solutions to ‘lock’ the catheter lumen after insertion and between dialysis treatments, as well as non-microbial agents such as citrate taurolidine, and chlorhexidine.(8, 19, 20) Other interventions include catheter dressing types (21), catheter dressing frequency (22), catheters with subcutaneous tunnels (23) and, more recently, antimicrobial catheter lumen caps that form a physical and antimicrobial barrier at the closure of the dialysis catheter.(24) A recent review highlighted the complexity of this literature, presenting challenges for clinicians in untangling the evidence to decide upon optimal catheter care.(25) In addition, various hospital departments may play a role in managing any single HD CVC complicating care and making standardization difficult.(6)

3. Evidentiary limitations The difficulties posed by the literature examining HD-CRBSI are perhaps best illustrated by the differing and often outdated recommendations from guideline groups. The Australia/New Zealand (ANZ) guideline, published in 2012, made a single recommendation based upon high grade (level 1) evidence, and the Canadian guidelines from 2006 made two recommendations with high level evidence.(26, 27) The US guidelines published in April 2020 make multiple recommendations around the use, insertion, management and removal of HD-CVC’s most of which remain based on expert opinion or at best moderate level of evidence.(28) .(29) The limited recommendations, whilst reflecting the available literature at the time of guideline production, is a notable contrast to the myriad elements of catheter insertion, management and care. The guidelines also highlight the gaps in this literature, most notably the paucity of head-to-head studies comparing differing treatments and approaches, such that their relative benefits remain unclear. (23)

In contrast, the CDC guidelines for the prevention of intravascular catheter-related infections updated in 2017 cover 20 sub-topic areas, illustrating the complexity of what most clinicians would consider a relatively routine part of clinical nephrology care.(30) The final recommendation, that of using collaborative performance improvement initiatives and multi-faceted strategies to improve practice, has been central to the development of the REDUCCTION trial.

Many other elements such as insertion site, showering/bathing, use of sterile techniques at insertion and when accessing the catheter, frequency of dressing changes and patient factors (such as socioeconomic status, comorbidities, residence characteristics and patients’ understanding of catheter care) could also influence HD-CRBSI, but are not readily studied. Furthermore, much of the current evidence arises from small studies, many of low quality, testing differing interventions with variable outcome reporting. These characteristics make the distillation of findings into a coherent and implementable practice change at a service level difficult and allow variability in clinical practice to flourish.(25, 31-33) 5

4. Practice variation A survey of ANZ renal services demonstrated wide variation in the processes around catheter care, such as prophylactic antibiotic use, exit site dressings and catheter insertion personnel.(6, 34) This showed that prophylactic antibiotics were used at 21% of renal services and eight different combinations of exit site dressing were in use, with an antibiotic patch being most common (35%).(6)

Reducing such variation has, had some success in reducing CVC-related bacteremia. The Keystone ICU project used a suite of interventions to address healthcare-associated infections, most notably CVC-associated bacteremia, and showed significant reductions in this outcome.(11)

The REDUCCTION trial aims to systematically measure the use of HD CVCs for dialysis access at a national level in Australia, to accurately determine the rate of HD-CRBSI and test the effect of a multifaceted, evidence-based intervention upon the rate of HD-CRBSI.

Methods

Design REDUCCTION uses a stepped-wedge cluster design (Figure 1) (35), clustering the intervention at the renal service level, ensuring that all participating services receive the intervention and serve as their own control. The application of such an intervention at the individual patient level was impractical due to the requirement of having two (or more) systems of HD CVC management within each service and the risk of “contamination” of the intervention practices into the control group. This approach implements the entire suite of interventions at a service level, minimizing contamination, uses the benefits of randomization in the timing of the application of the intervention, and accommodates for changes in practice that occur with time. The trial was registered on the Australia New Zealand clinical trials registry on the 23 June 2016 (ACTRN12616000830493).

Setting The trial is being conducted at 37 renal services across Australia which, collectively, manage 75% of the Australian prevalent dialysis population (Table 1). Many services oversee multiple dialysis facilities, such that a service is defined as a site, or sites (usually hospital-based in Australia), under the same clinical governance as it pertains to clinical decision making around HD CVC management. Australia has a universal health insurance system, covering the costs of inpatient public hospital care and varying proportions of outpatient health services. Dialysis is largely provided in public and is covered by the national insurance scheme, and private facilities manage a small proportion of dialysis patients.

Participant inclusion criteria All Australian renal services were approached to participate in the trial in 2016, with 37 proceeding to enrolment. Adult patients who have a HD CVC inserted after the start of the trial at a participating renal service are eligible for inclusion in the data collection. Prevalent dialysis catheters inserted 6

prior to the start of the trial are excluded. Data are collected from the time of HD CVC insertion, or the time the HD CVC comes under the care of the renal service, until the HD CVC is removed, no longer under the care of the renal service, or end of the trial.

Informed Consent Ethics approval was obtained according to institutional processes across 8 states and territories (Supplemental Table 1). The trial uses two approaches to consent; an ‘opt-out’ approach or a ‘waiver of consent’ approach, as decided by local research governance.(Table 1) Renal services using the ‘opt-out’ approach allow patients to opt-out of the data collection following provision of a trial information sheet, but the renal service continues to treat such patients as per the service’s participation in the trial. Services with approval to use the ‘waiver of consent’ approach are not required to perform any study-related consent activities. Any participant is able to decline participation in the data collection at any point in the trial.

Data collection methods A web-based data collection tool was custom designed for the study and data entered by each participating service. Renal services can see, in real-time, all dialysis catheters currently in use, and the total exposure of patients to dialysis catheters over various time periods. Services are able to see their own rates of HD-CRBSI during the baseline phase and, during the trial intervention phase, can also see the HD-CRBSI rate across the entire trial.

The data collection includes baseline patient and catheter characteristics and classifies catheters by their reason for insertion: initiation of maintenance hemodialysis, acute kidney injury requiring hemodialysis (HD CVC is managed by the renal service), interim hemodialysis due to failure of an existing dialysis access e.g. failure of peritoneal dialysis, or thrombosis of an existing arterio-venous fistula. Data on interventions upon the dialysis catheter (e.g. rewiring, re-suturing), surgery for creation or revision of permanent dialysis access, the reasons for catheter removal, and the results of any blood or catheter tip cultures are also collected. (Supplemental Table 3) In addition, service- level data on existing practices around catheter care and dialysis activity within each renal service at trial initiation and prior to implementation is collected. Services were discouraged from making changes to the processes of care for HD CVCs during the baseline phase of the trial.

Reporting of HD-CRBSI uses a standardized definition (Table 2) and a central blinded adjudication process. All possible HD-CRBSI events are reviewed by two adjudicators (clinicians who are independent from the research team). Disagreement between the two adjudicators requires review from the third adjudicator. If agreement is not reached by the third adjudication, the Trial Management Committee) reviews the de-identified event.

Data linkage to state-specific hospitalization and death datasets will complete at the end of the intervention phase, after all trial data collection has ceased, allowing analyses of long-term patient outcomes and economic impacts of catheter complications. 7

Interventions and Implementation The suite of evidence-based interventions, designed by a sub-committee of the REDUCCTION Steering Committee in consultation with the Australasian renal guidelines group (36) and the Australian consumer body (Kidney Health Australia) , was endorsed by the Trial Management Committee. The interventions were informed by the most current evidence at the time of design, including the Keystone Project in Michigan ICUs (15, 16), expert opinion across ANZ and were finalised in January 2018. The components of the intervention were separated into three timepoints in catheter use – insertion, maintenance and removal and were deemed as guiding rather than prescriptive (Figure 2).

All services implemented the entire suite of interventions at their randomly assigned time point, overseen by local physician and leaders. The delivery of the intervention training was in the form of three short videos (one for each component of the intervention) delivered to the service 6 weeks prior to the implementation of the interventions as well as a pre-intervention teleconference. Upon intervention implementation, the data collection tool was modified to allow each service to compare the primary outcome, HD-CRBSI, at their service with the study-wide rate, and additional data prompts and fields were added to remind service staff of the intervention components and allow monitoring. (Supplemental Table 4)

Blinding Blinding of the trial intervention is not possible, but the timing and nature of the trial interventions was kept confidential and revealed prior to implementation at each service. Services were asked to keep the intervention confidential until all services had implemented the intervention.

Outcomes The primary outcome of the trial is the comparative rate of HD-CRBSI per 1000 catheter days of exposure, between the baseline and intervention trial periods (Table 2). A modified version from the the Infectious Diseases Society of America definition was used to define HD-CRBSI as detailed in Table 2.(37) The secondary outcomes are suspected or possible HD-CRBSI; total suspected and possible bacteremia (Table 2).

Statistical methods A covariate-based constrained randomization determined the division of participating services into three balanced tranches and the commencement of the intervention over the trial period.(35, 38) The allocation sequence was informed by the total number of catheters inserted in the baseline phase of the trial (December 2016 - January 2018). One hundred thousand random allocation sequences were generated, and those that achieved a degree of balance of no more than a 10% different from the average number of dialysis catheters in the trial (between 73.2-89.8 average catheters per arm) were retained. Of the original sequences generated, 6865 met our balance criteria, and the final randomization allocation was chosen randomly from this subset.

Pilot data collected from a Sydney service (unpublished) allowed us to estimate that an average of 100 dialysis catheter insertions (100 observations) occurred per year at a medium sized Australian 8

renal service (defined based on number of dialysis patients as per ANZDATA), with each catheter lasting for a mean of 46 days. The expected rate of baseline HD-CRBSI was 2.5 per 1000 catheter days, derived from a combination of pilot data and the published literature at the time.(17) Further considerations included the inter-cluster correlation co-efficient (ICC) which we estimated at 0.07 when the rate seen in a large US study from 2014 was 0.03, (9) and the number of intervention points (number of steps) planned was three. The powering was based upon the intervention resulting in a 50% reduction in the risk of catheter-related bacteremia which was a conservative estimate based on the Key Michigan project outcomes.(11, 39)

On the basis of these figures, the trial was estimated to have a power of over 0.9 to detect a 50% reduction in the bacteremia rate using a proposed sample of 30 renal services 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, 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 services, and the trial has included 37 renal services to ensure that 100 patients per ‘step’ during implementation is met. A formal statistical analysis plan has been derived for the trial and will be published on the REDUCCTION study site. (URL to be confirmed).

Additional analyses There are two planned sub-group analyses of the primary outcome. The first examining for differences in the primary outcome on the basis of renal service size, and the second on the basis of whether renal services were using either an impregnated dressing or an antimicrobial catheter lock, as per the KHA-CARI guidelines (27), at baseline. A prospective process evaluation is being conducted during the baseline and intervention phases of the trial to better understand the factors that influence the implementation of evidence-based practices around dialysis catheter management.(40)

In addition, this uniquely large prospective cohort of patients receiving dialysis catheters will allow future exploration of the effects of a variety of factors, including renal service, patient, clinical and HD CVC characteristics upon important patient outcomes such as HD-CRBSI, hospitalization, and mortality. These analyses will use trial data and linkage to administrative (hospitalization and death) datasets, allowing assessments of the healthcare costs of catheter practice.

Key Limitations A limitation of the trial and its design is that the completeness of data collection is not known, and there is a risk that this could change between baseline and intervention phases. Potentially the risk of the primary outcome across services may also have varied between the two study phases, but the absence of tools to guide clinicians in such patient selection makes this unlikely. Most importantly, the Hawthorne effect may impact the trial outcomes: the phenomenon whereby individuals change their behavior as a result of their knowledge of being observed.(41) To mitigate this, services are discouraged from changing to their clinical practices around catheter care during the trial, beyond those changes arising from the trial intervention. The risk of under-reporting of HD-CRBSI remains but is mitigated by the requirement to centrally report all possible infectious events and the central adjudication of these events. 9

Results

Participant characteristics Data collection commenced on the 20th of December 2016 and is ongoing. A provisional extract from the trial dataset, encompassing the intervention phase at all services, includes data on 5385 HD CVCs in 3615 participants, representing 603,506 days of HD CVC exposure.

The average age of the participants was 63.0 years (IQR 50-73.0 years), 60.1% (n=2174) were male, and 43.7% (n=1578) had diabetes (Table 3). The majority of HD CVCs inserted were tunnelled catheters with a median catheter duration of 90.0 days (IQR 28-207 days). Non-tunnelled HD CVC had a median catheter duration of 6 days (IQR 3-8 days).

The major indications for HD CVC insertion were for acute kidney injury (n=1896, 35.0%), or for initiation of maintenance hemodialysis without permanent access (n=1703, 31.6%) (Table 4). The majority of tunnelled catheters were inserted by interventional services (n=2699; 67%) while the non-tunnelled catheters were inserted predominantly by intensive care units (n=753; 55.8%). The internal jugular vein was the most popular site for HD CVC insertion (total 4619; tunnelled =3780 (81.8%); non-tunnelled= 838 (18.1%)) with femoral being the second most popular site (total 577; tunnelled =83 [14.4%]; non-tunnelled= 494 [85.6%]).

Conclusion

REDUCCTION is a large stepped wedge cluster randomized trial which systematically measures the use of dialysis catheters across 37 Australian renal services in real-time. It will study the effect of a standardized suite of evidence-based interventions around catheter care upon the rate of HD-CRBSI at the service level and, by virtue of its scale and robust design, will provide novel insights into dialysis catheter care and its impacts upon patients.
