Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Background: The investigators developed a Shower Technique protocol (STP) for hemodialysis (HD) patients with healed central venous catheter (CVC) exit sites, designed to permit showering but not increase infection risk.

Research question: Is it feasible to conduct a randomized control trial comparing the rate of CVC related bacteremia (CRB) in adult satellite HD patients using STP versus standard CVC care alone with 6 month follow up? Study Design: This pilot study is a multi-centre randomized control trial. Eligible participants will be randomized to STP versus standard care after meeting predefined criteria to confirm healed tunneled CVC exit site.

Primary Outcome: Feasibility will be determined based on 5 outcome measures: accuracy of the CRB rate documentation in the satellite setting, percentage of patients screened, recruited, educated successfully in the STP (intervention arm), and aspects of STP (% of contaminated patients in the control arm).

Study Setting: In satellite units affiliated with 2 academic and 3 community centres in south central Ontario, Canada.

Patient Population: Adult satellite HD patients dialyzing via CVC with healed CVC exit sites.

Intervention: STP and standard CVC care; or Control: standard CVC care; Analysis: Each measure of feasibility has its statistical threshold for success. If the threshold is reached in 4 of the 5 measures, the full HIPPO SAT study will be deemed feasible.

Discussion: A pilot feasibility study of the larger study is critical due to the potential challenges associated with recruitment, compliance and contamination.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

CVC related infections are associated with increased morbidity and hospitalization rates, high treatment costs, and poor survival compared to use of an arteriovenous access. To prevent infection, patients should preserve the integrity and dryness of their CVC dressings. Showering should be avoided, as it is difficult to attain full protective coverage of the exit site using dressings and barriers. Wet dressings place patients at increased infection risk, especially if their CVC exit site is not fully healed. However, in a survey of 274 CVC dependent HD patients, 64% indicated that the recommended prohibition to shower was moderately to extremely inconvenient and reduced their quality of life. Additionally 77% of patients admitted to showering at least once while they had a CVC.

While submersion of the CVC in water is discouraged by clinical practice guidelines, they also state that if precautions can be taken to reduce the likelihood of bacterial CVC entry then showering may be acceptable. However, this guidance is opinion based with no evidence to support specific precautions. Thus, to address the patients' desire to shower safely, at least 2 separate dialysis facilities in Ontario, Canada have developed a showering procedure as an alternative method of CVC care. Preliminary data from a small proof-of-concept study of 65 patients suggests acceptable CRB rates (0.46/1000 CVC days) using such showering procedures. The study was conducted in satellite HD units on a select population of patients who were infection-free for 6 months using the same CVC. Satellite units offer dialysis in an outpatient setting for those patients who are stable and require less intensive care than in-centre patients. The satellite HD population is typically younger and healthier, and likely more able to perform showering procedures than in-centre patients. With increasing patients in satellite HD, it is crucial that a pragmatic, yet effective, prophylactic CVC infection strategy be formally tested and established for this setting.

Following the proof-of-concept study, nephrologists, vascular access coordinators, and HD centres from five dialysis centres across Ontario, collaborated to create a formal Shower Technique Protocol (STP) which includes chlorhexidine applicators after showering to minimize the risk of bacterial entry at the CVC exit site. STP is designed specifically for patients with a fully endothelialized CVC tunnel and healed exit site. Participants allocated to STP are able to shower and change their dressing up to 3 times per week. Prior to more widespread implementation of the STP, it is critical to determine whether it is safe for use in patients with healed CVC exit sites. In other words, to confirm that CRB rates in patients using STP are not greater than the CRB rates in patients using the gold standard of CVC care. It is unknown whether using the STP improves patient satisfaction with their CVC care.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Shower Technique Protocol (STP)

Participants will be given a minimum 30 minute personalized educational session by the study coordinator. They will be taught safe and clean techniques for showering with their CVC. If the participant passes the Shower Technique Test, they will be provided a pamphlet on the STP, not to be shared with other participants, to be kept as a reference and placed in their bathroom/household. They will also be given the necessary supplies for the STP.

Group Type EXPERIMENTAL

Shower Technique Protocol

Intervention Type OTHER

Video and educational pamphlets of the STP will be used to assist in training participants randomized to this intervention. The participant must successfully demonstrate the STP on a training mannequin and be deemed by the study coordinator as ready to independently and correctly perform it before proceeding.

Standard CVC Care

Intervention Type OTHER

Nuanced differences may be present at participating units; however, the key components of the intervention are 1) HD nurse delivery of CVC care 2) chlorhexidine or povidone cleansing 3) dry gauze dressing 4) standardized frequency. For both STP and control arms, participants whose HD centre uses polysporin triple ointment as part of standard CVC care will continue to have it applied as per program policy.

Standard CVC care

Standard CVC Care consists of cleansing with chlorhexidine 2% or povidone (if allergic to chlorhexidine) at the CVC exit site by trained HD nurses followed by placement of a dry gauze dressing by the HD nurse 1x/week or when clinically indicated. In order to participate in the standard CVC care arm, participating sites must have in their policy that it is trained HD nurses who will apply the Polysporin Triple Ointment after standard cleansing with chlorhexidine 2% or povidone during HD, according to guideline recommendations or as per hospital patient care standards and nursing regulations.
