Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
At time of PICCs are indicated for insertion (as identified by screening of PICC insertion theatre and medical imaging lists), patients will be randomised to receive either:
Arm 1) Anti-thrombogenic PICC (size decided by clinician due to vascular size and treatment requirements) BioFlo PICC with PASV (by Angiodynamics®)
Arm 2) Anti-microbial (chlorhexidine gluconate [CHG]) PICC (size decided by clinician due to vascular size and treatment requirements) Arrowg+ard Blue Advance PICC (by Teleflex®).

The allocated PICCs will be provided by the research nurses to the PICC inserter (i.e. physician or nurse; not research staff) immediately prior to PICC inserting procedure. The research nurse will then assess the appropriate PICC has been placed within 24 hours of insertion. The PICCs will remain insitu for the entire treatment duration, as clinically indicated (i.e. the discretion of the clinician).

The haematology substudy will evaluate the same intervention products and patients.

Secondary outcome [13] 355080 0
Sub-study: Bacterial colonisation and CHG resistance: PICC tips removed due to suspected infection and a control group of tips; will be cultured using the roll-plating method on blood agar, with quantification of colony forming units, species identification using Vitek-MS (BioMerieux) and susceptibility testing for a standard panel of antibiotics by Vitek 2 automated broth microdilution. In addition, CHG tolerance will be tested by determining minimum inhibitory concentrations (MICs) against organisms isolated from PICC tips using broth microdilution (with an MIC less than or equal to 4 mg/L defining reduced susceptibility to CHG). Genes known to be associated with CHG tolerance (e.g. qacA/B and smr) will be confirmed by PCR. In patients with suspected CASBI and the same species grown in PICC tip cultures, organisms isolated from both blood and tip cultures will have DNA extracted and whole genome sequencing performed on the Illumina MiniSeq platform. Raw reads will be trimmed, checked for quality, assembled and analysed using a custom pipeline to confirm species identification, define in silico multi-locus sequence type (MLST) and detect the presence of any antibiotic resistance genes. Other genes known to be associated with CHG tolerance and biofilm formation will be sought by BLAST against the assembled genomes. To confirm whether PICC tip and blood culture isolates are clonal, core genome differences between blood and PICC tip isolates are being determined by comparing single nucleotide polymorphisms.

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)
The research nurse (ReN) will screen patients daily (screening Log kept). The study ReN will gain informed consent and perform randomisation. The RN will have the study products in pre-packs and liaise closely with the ordering and inserting clinician. All eligible patients will be approached for written informed consent by the ReN or inserter. If this is given, the staff member uses a centralised web-based randomisation service. Allocation is fully concealed until the patient is randomised.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The ReNs will randomise patients via a central web-based service immediately prior to each PICC insertion to ensure allocation concealment until study entry. Randomisation (patient level) will be a 1:1:1 ratio between groups with randomly varied block sizes (up to 20) and stratification by: (i) hospital and (ii) hypercoagulable state (Adults: high risk of thrombosis as per Michigan Risk Score; Paediatrics; previous thrombosis or active cancer).

Statistical methods / analysis
The key presentation principle is complete-case intention to treat. All participants who were randomized and have evaluable data for the endpoint under investigation will be analysed in the study arm to which they were randomized.

Per protocol analysis will be performed to test the sensitivity of the results to noncompliance. In per-protocol analyses all participants who were randomized, were treated with the device they were randomized to receive and have evaluable data for the endpoint under investigation will be analyzed. in the study arm to which they were randomized. The number of missing observations for each primary and secondary outcome will be reported by study group. If the proportion of missing observations is non-trivial (>5%), consideration will be given to the possible introduction of compliance and attrition bias. The cause of any missing data will be assessed. Sensitivity analyses to investigate the potential impact of stratification variables and missing data will be undertaken by (i) adjusting regression models for covariables included in stratification and (ii) imputing missing data using multiple imputation methods and re-running regression models if appropriate. Any multiple imputation will occur using chained equation methods.

Continuous data will be summarized descriptively using either mean and standard deviation (SD) or median and interquartile range (IQR), depending on the distribution of the variable of interest. Categorical data will be presented as frequencies and percentages. A significance level of alpha = 0.035 will be used to evaluate statistical significance for the primary outcome.

The number and proportion of device’s which experience the primary outcome PICC failure (fail/not fail) will be calculated per group. Between-group differences (hydrophobic vs standard polyurethane and CHG vs standard polyurethane) will be analyzed using logistic regression with study group as the main effect. The result will be presented as an odds ratio (95% CI); P value. To test the sensitivity of the primary outcome between-group comparisons will be stratified by site in order to investigate the level of variability across sites.
