Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Other than the study intervention, (type of peripheral intravenous catheter (PIVC) inserted), all other aspects of PIVC management will be as per local clinical guidelines (Royal Brisbane and Women’s Hospital, 000259: Peripheral Intravenous Cannulation and Infusion Management – Adult and Paediatrics). Hand hygiene is required prior to and throughout the insertion procedure. Skin will be prepped and decontaminated using a large swab or swab stick containing 2% Chlorhexidine Gluconate with 70% isopropyl alcohol. The antiseptic must be allowed to dry prior to inserting the IV catheter. Palpation of the insertion site should not be performed after the application of antiseptic, unless aseptic technique is maintained. If the health professional needs to re-establish the identification of the vein, the site should be re-prepped with the antiseptic solution and allowed to thoroughly dry. It is more efficient to assess the patient’s veins at the outset, determine degree of difficulty of insertion and then risk assess to ascertain if it may be more effective to wear sterile gloves to enable palpating of the cleansed area thereby maintaining Aseptic Non-Touch Technique (ANTT®). Site selection will be determined by inserter following assessment of the patient’s vessel health and in consultation with radiographer/radiologist about procedure and infusion protocol.

Study and control PIVCs will be inserted by trained clinicians (either clinical staff or research nurses), who are existing skilled or competent intravenous inserters. Pre-trial they will have training and simulated practice inserting the study PIVC, until they feel confident that their skills match their competence for control PIVC insertion. If ultrasound is used to guide insertion, this will be recorded. Weekly checks by Research Nurse (ReN) for protocol fidelity will be conducted.

A sterile transparent, semi-permeable, self-adhesive IV dressing must be placed over the insertion site (as per manufacturer recommendations). The PIVC is removed when prescribed therapy is complete or as clinically indicated.

Participants allocated to the Intervention group will have a 20g or 22g (as per clinician preference and assessment), 31.75mm BD NexivaTM DiffusicsTM catheter inserted and used for infusion of contrast. This device has both side and end hole exit points at the distal tip, as opposed a single end hole exit point in standard (control) catheter. Pre-packs of allocated products will be kept in storeroom and monitored daily by the research nurse, who will also confirm time and reason for replacements with nursing staff.

Outcomes
Primary outcome [1] 322066 0
The primary outcome Study feasibility: The feasibility outcome will be determined based on the following criteria:
i. Eligibility: over 90% of screened patients meeting all inclusion and no exclusion criteria;
ii. Recruitment: over 90% of eligible patients providing informed consent (or not opting out);
iii. Retention: fewer than 5% of recruited patients lost to follow up or withdrawing consent;
iv. Protocol fidelity: over 90% of randomised patients receiving their allocated intervention;
v. Missing data: less than 5% of primary endpoint data unable to be collected by study staff; and
vi. Patient and staff acceptability with the study intervention and control: 70% of patient/parents and staff scoring greater than or equal to 7 on a 0-10 point rating scale at study completion.
Timepoint [1] 322066 0
Feasibility outcomes calculated from trial screening logs and database. Protocol fidelity determined from weekly (observational) practice audit and verbal reports by staff. Staff will be invited for to give feedback at the end of the trial.
Primary outcome [2] 322067 0
The primary outcome is PIVC failure (composite endpoint) for reasons of: occlusion, infiltration/extravasation, phlebitis/thrombophlebitis, dislodgement, haematoma, localised or bloodstream catheter-related infections. a) Occlusion is defined as the inability to infuse or inject solution into a catheter. b) Infiltration/extravasation infiltration is defined as the inadvertent permeation of IV fluid (non-vesicant solution) into the interstitial compartment, causing swelling of the tissue around the site of the catheter. Extravasation is the inadvertent administration of a vesicant solution into surrounding tissue. c) Phlebitis/thrombophlebitis phlebitis is defined as irritation and inflammation of a vein wall caused by the presence of the PIVC. It is characterised by the presence of any combination of tenderness, pain, erythema, swelling, warmth, palpable cord, or purulent drainage. In this study phlebitis includes pain (>1 out of 10) alone or plus any of the criteria mentioned above (on questioning, then palpation by the research nurse). Thrombophlebitis is also characterised by a visible clot on removal and/or palpable thrombosis of the cannulated vein. All these are consequence of the inflammation of the vein wall that leads to thrombus formation. In this study the presence of thrombophlebitis will be confirmed by ultrasound of the compromised vessel (if ordered by clinicians). d) Dislodgement is defined as movement of the catheter in and out of, or around and within, the vein resulting in partial or complete dislodgement. This may be characterized as Leaking (partial dislodgement). e) Haematoma is defined as solid swelling of clotted blood within the tissue, caused by a break in the wall of the blood vessel due to the insertion of a PIVC, resulting in device malfunction and triggering the removal of the catheter.' f) Localised venous infection is defined as organisms grown from purulent discharge or vein segment with no evidence of associated bloodstream infection. g) Bloodstream infection is defined as positive blood culture from a peripheral vein; clinical signs of infection (i.e. fever, chills, or hypotension); no other apparent source for the bloodstream infection except the intravenous catheter (in situ within 48 h of the bloodstream infection); and either a colonised intravenous catheter tip culture with the same organism as identified in the blood or purulent drainage from the involved vascular site.

Secondary outcome [2] 377197 0
Device colonisation: Approximately 20 PIVCs (10 from each group) will be analysed by the semi-quantitative method in the QUT QIMR laboratory. PIVCs will be selected based on availability of the Research Nurse when the PIVC is removed and when transfer to the lab is available. Colonisation of intravenous catheter tip will be considered if more than 15 colony-forming units are present. Blood cultures from a peripheral vein, and PIVC skin swabs (if ordered by clinicians) will be cultured by Microbiology Pathology Queensland-Central Lab by blinded scientists

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A participant will be considered enrolled into the study if the participant has met all inclusion criteria and none of the exclusion criteria. The participant will receive a study enrolment number and this will be documented in the participant’s medical record and on all study documents. A separate master log will be created to link the participant’s study number to their medical record. Randomisation will be via a centralised web-based service, which will ensure allocation concealment until study entry. Randomisation will be in a 1:1 ratio between the two groups with randomly varied block sizes. Study products will be in pre-packs and ReNs will liaise closely with clinicians.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation)

Statistical methods / analysis
Feasibility outcomes will be reported descriptively. All randomised patients will be analysed on an Intention to Treat (ITT) basis. Patients will have one PIVC entered in the study so that the unit of analysis (the patient) is independent. For this pilot trial, we will test the feasibility of the statistical analysis that will be used in the definitive trial. Prior to analysis data will be cleaned and checked. All attempts will be made to collect the primary endpoint (PIVC failure (Yes/No). Comparability of groups at baseline will be assessed using clinically relevant indicators and compared statistically using chi-squared tests to compare differences in categorical variables and independent samples t-tests to compare differences in continuous variables. Frequency and Incidence Rate Ratio (with 95% confidence intervals) of device failure will summarise the impact of the intervention. Secondary endpoints will be compared between groups for clinically significant differences, with the impact of the intervention on dwell times assessed using hazard ratio (with 95% confidence intervals) estimated from a Cox proportional hazards model and the impact of the intervention on categorical variables assessed by frequency and incidence rate ratios (with 95% confidence intervals). P values of <0.05 will be considered statistically significant.

Summary
Brief summary
Peripheral intravenous catheters (PIVCs) are small plastic tubes inserted into veins to deliver essential fluids, medications and blood products. Cancer care patients are ‘high end users’ of PIVCs and other vascular devices necessary to receive both anti-cancer and adjunct therapy, including repeated scans using injectable contrast dye for diagnosis and staging. However, current failure rates of PIVCs are unacceptably high (40-50%). Preservation of vessel integrity and reduction of infection risk is a high priority in this vulnerable patient population. This study aims to test the feasibility of evaluating perforated versus non-perforated peripheral catheter design on PIVC complications and failure. Sixty patients (30 per treatment group) requiring injection of contrast via PIVC for a Computerised Tomography (CT) scan for diagnosis or staging of malignant oncology or haematology conditions, will be enrolled. In addition to feasibility outcomes, the impact on device failure and vessel integrity will be evaluated. The results will lay the foundation for follow on trial work and grant applications to support this. Preventing hospital acquired complications is a priority area in modern healthcare.
