Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in this study are patients who require intravenous catheters (IVC) in emergency departments (ED). Consenting participants will receive a IVC inserted by a Vascular Access Specialist (nurses trained in ultrasound-guided IVC insertion) in the intervention group when a PIVC is required in ED. The IVC will remain in situ as long as it is required as per hospital policy. The insertion length of the IVC vary depending on the complexity of patient's venous condition and device is required. Patients will be monitored daily by a research nurse.

Outcomes
Primary outcome [1] 339135 0
First insertion success rate: on first insertion attempt, there is a visible presence of blood at IVC hub afterpiercing through the skin into the vein, and a successful flush of normal saline into the vein is achieved.
Timepoint [1] 339135 0
At the time of IVC insertion in ED.
Secondary outcome [1] 438687 0
Number of insertion attempts: needle punctures to insert device.
Timepoint [1] 438687 0
At the time of IVC insertion in ED.
Secondary outcome [2] 438688 0
IVC failure rate: any causes of ‘failure’ including infiltration/extravasation, occlusion, dislodgement, infection (laboratory-confirmed local or bloodstream infection), phlebitis and thrombosis (confirmed by ultrasound).
Timepoint [2] 438688 0
Daily from IVC insertion until 48 hours after IVC removal.
Secondary outcome [3] 438689 0
Individual complications: infiltration/extravasation, occlusion, phlebitis or infection (positive blood culture from the peripheral vein; clinical signs of infection with no other apparent source except the IVC; and localised IVC site infection (without bloodstream infection).
Timepoint [3] 438689 0
Daily from IVC insertion until 48 hours after PIVC removal.
Secondary outcome [4] 438690 0
Device dwell-time: time from insertion to removal (in hours). This will be assessed by either the Research Nurse (during daily checks), or (if identified by the treating clinician) recorded on a 1 page data collection sheet at the patient's bedside or in the patient's medical record.
Timepoint [4] 438690 0
At the time of IVC removal.
Secondary outcome [5] 438691 0
Number and type of devices needed to complete IV treatment: Total numbers and types of vascular access devices are needed to complete IV treatment when patients are discharged from hospital or no vascular access devices are placed after 7 days.
Timepoint [5] 438691 0
At the end of discharge or 7 days post removal of the previous vascular access device
Secondary outcome [6] 438692 0
Patient satisfaction: on a 11-point Likert scale.
Timepoint [6] 438692 0
At the time of IVC insertion in ED.
Secondary outcome [7] 438693 0
Staff satisfaction: on a 11-point Likert scale.
Timepoint [7] 438693 0
At the time of IVC insertion in ED.
Secondary outcome [8] 438694 0
Cost data: will be collected at both arms. It will focus on collecting direct variable costs (e.g. cost and number of products used and staff for device insertion; costs of treating complications) in a subset of 30 per arm.
Timepoint [8] 438694 0
Daily from IVC insertion until the time of IVC removal.

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)
Research nurses will screen patients daily and liaise with the staff responsible for inserting IVCs in ED. All eligible patients will be approached by staff who will ask patient's permission to be approached. Once they agree, a written informed consent will be obtained by the research nurse. If this is given, the research nurse will log into a centralised web-based randomisation service customised for the trial and be advised of groupallocation. Computer generated allocation is provided by an independent 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)
Randomisation will be in a 1:1 ratio between the two study groups.

Efficacy
Statistical methods / analysis
All randomised patients will be analysed on an Intention to Treat basis. The patient is the unit of measurement with one IVC per patient being analysed. Categorical data will be presented as frequencies and percentages. Continuous data will be presented as means and medians.
Logistic regression will be used to assess first insertion success. Kaplan-Meier survival curves will compare time to device failure rate. Continous variables will be presented as linear regression. Binary outcomes comparsion will use logistic regression while count outcomes by Poission regression. Multivariate regression (Cox) models will test the effect of patient and device variables associated with device failure.Data will be exported into Stata. Prior to analysis, data cleaning of outlying figures, missing, and implausible data will be undertaken, and a random 5% sample of source data re-entered and checked.
Missing data will be modelled for best- and worst-case outcomes to assess for effect on overall results. P values of <0.05 will be considered significant.
