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.

Allocation to intervention
Randomised controlled trial
Query!
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.

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.

Summary
Brief summary
The primary aim of this randomised controlled trial (RCT) is to compare the clinical and cost eff ectiveness of new Vascular Access Specialist model with the Generalist inserter model (inserted by a doctor or nurse in emergency department). You may be eligible to participate in this trial if you are an emergency department patient more than theage of 18 and are requiring a peripheral venous catheter inserted as part of your therapy. All participants enrolled in this trial will be randomly allocated (by chance) to receive one of two options (inserted by either a Vascular Access Specialist or a doctor/nurse in emergency department). Participants and families will be asked to rate the satisfaction of the insertion, and the peripheral intravenous catheter will be observed closely to examine side effects. It is hoped that the findings of this trial will provide information on which insertion model is the most effective in preventing first insertion failure.
