Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients in this study have peripherally inserted central catheters (PICCs) in medical, surgical, anaesthetic and intensive care departments, and only paediatric patients. Consenting parents or legal guardians, and patients (if appropriate) will have their PICCs secured with one of the following randomly assigned dressings and securements:

Arm 1: Tissue Adhesive (TA) is a medical grade 'superglue'
(cyanoacrylate) used mainly to close skin lacerations/wounds as an alternative to sutures and staples. A bordered polyurethane dressingwill also be applied.

Arm 2: Combined securement and dressing product: extra-reinforced borders, with an absorbent layer around the polyurethane claimed to ‘wick’ moisture away from the wound

Arm 3 (Control): Sutureless Stabilisation Device (SSD) have a large adhesive padded footplate with locking clasp made of hard plastic. SSD are used in addition to bordered polyurethane. Bordered polyurethane (BPU) dressings involve a clear
polyurethane with an added external adhesive border of foam or cloth fabric.

The randomly allocated dressing will be applied until completion of therapy, hospital discharge or at 4 weeks. The dressing will be applied at PICC insertion and then changed every 7 days, or on disruption of the dressing integrity.

Outcomes
Primary outcome [1] 293778 0
PICC failure or complication: Composite measure of any reason for unplanned PICC removal or complication, prior to the completion of therapy. This includes (i) Central Line-Associated Bloodstream Infection (CLABSI); (ii) local infection of skin or sutures: (iii) dislodgement: (iv) occlusion; (v) CVAD breakage or (vi) venous thrombosis. The primary outcome of device failure is an objective measure, assigned by clinical staff (not research staff or investigators). This is routine clinical practice. Research staff will collect the primary endpoint from the medical records with additional information obtained from the clinical staff/patients if required

Secondary outcome [1] 311805 0
Central line-associated bloodstream infection (CLABSI):
A laboratory-confirmed bloodstream infection (LCBI) in a patient who had a central line within the 48 hour period before the development of the BSI, and that is not related to an infection at another site. The CLABSI must meet one of the following criteria of LCBI: Criterion 1: Patient has a recognised pathogen cultured from one or more blood cultures and
Organism cultured from blood is not related to an infection at another
site. OR Criterion 2: Patient has at least one of the following signs or
symptoms: fever (greater than 38 degrees C), chills, or hypotension, and signs and symptoms and positive laboratory results are not related to an infection at another site, and common skin contaminant* is cultured from two or more blood cultures drawn on separate occasions. Examples of common skin contaminants: diphtheroids [Corynebacterium spp.], Bacillus [not B. anthracis] spp., Propionibacterium spp., coagulasenegative staphylococci [including S. epidermidis], viridans group streptococci, Aerococcus spp., Micrococcus spp.

Dislodgement:
Partial: any post-insertion change in the length of the PICC body from the hub to the PICC tip, as measured by the catheter marking in closest approximation to hub.
Total: PICC body completely leaves the vein, or must be removed because PICC tip is no longer in the superior vena cava (diagnosed by XRay/leakage from site on injection/clinician diagnosis)

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 (RN) will screen patients daily (screening log kept), gain informed consent, and perform randomisation. The RN will have the study products in pre-packs and liaise closely with the ordering and inserting surgeon. All elligible patients (or
their representative) will be approached for written informed consent by the RN or inserter. If this is given, the staff member use 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)
Computer generated. Randomisation will be in a 1:1:1 ratio between the three study groups. Permuted blocks in randomly varied sizes will be used.

Efficacy
Statistical methods / analysis
All randomised patients will be analysed by intention to treat, regardless of treatment received. The patient is the unit of measurement with one PICC per patient.
Feasibility outcomes will be described using descriptive statistics
including mean, median, range, IQR, counts and percentages.
Comparability of groups at baseline will be assessed using clinical parameters. Relative incidence rates of PICC and dressing failure per 100 devices and per 1,000 device days with 95% confidence intervals (CIs) will summarise the impact of each dressing, and to test difference between groups. Kaplan-Meier survival curves (with log rank Mantel-Cox test) will compare PICC failure over time. Secondary endpoints including dwell-time, costs, dislodgement, occlusion, breakage, patient/staff satisfaction scores and adverse events will be compared between groups using parametric/nonparametric
techniques as appropriate. Data will be exported into PASW 21.0 (SPSS Inc, Chicago, IL). Prior to analysis, data
cleaning of outlying figures, missing, and implausible data will be undertaken, and a random 5% sample of source data rechecked. All attempts will be made to collect the primary endpoint. Missing data will be modelled for best- and worst-case outcomes to assess for effect on overall results. A per-protocol analysis will assess the effect of protocol violations. P values of <0.05 will be considered significant.

Sample size and study power: This is a pilot study to gain information to prepare for an efficacy trial. Thirty participants per study arm will be recruited - totaling 90 participants.
