Interventional
Description of intervention(s) / exposure
The IV biosensor (ivWatch® sensor applied within 10–15mm of the peripheral intravenous catheter (PIVC) tip) plus standard clinical observation to detect extravasations and prevent extravasation injury.
The IV biosensor device consists of:
1. A patient monitor with audible alarm,
2. An optical sensor cable, and,
3. A sterile, disposable receptacle for attaching the sensor to the patient’s skin, near the PIVC site

The IV biosensor involves the blue sensor being placed over tissue / polyurethane dressing next to the vein between the intravenous (IV) insertion site and the IV tip (normally around 5-10mm from the insertion site) and plugged into the monitor.
Once applied, this sensor stays in situ until study end (i.e. IV removal or discharge from study hospital), unless the infant needs magnetic resonance imaging (MRI; due to metal in the sensor) or other treatments which are incompatible with the IV biosensor. The IV biosensor is to be applied on the day of enrolment for both newly inserted PIVCs and existing PIVCs.
The IV biosensor will be applied by member of the research team (a Clinical Research Nurse), and monitored hourly by the patient’s bedside nurse throughout the course of their admission or until their PIVC is removed. The patient’s bedside nurse will also continue to monitor the PIVC site hourly for signs of extravasation (per usual, standard clinical practice) in addition to monitoring the IV biosensor patient monitor. All other aspects of PIVC insertion, management and removal will be standardised in accordance with the hospital site’s clinical practice guidelines. Insertion, maintenance and removal will be performed by the usual interdisciplinary staff. The Clinical Research Nurse will monitor and record adherence to the protocol during a daily check.

The IV biosensor uses near infra-red light to continuously monitor the fluid pathway and surrounding tissue for early signs of extravasation. When fluid accumulates in the subcutaneous tissues, there is a significant change in the light scattering, which is recognised by the IV biosensor sensor and results in a “YELLOW CHECK IV” notification on the patient monitor, indicating the possibility of extravasation. If the infusion continues and the light signal further drops below the threshold, the patient monitor will return a “RED CHECK IV” notification, indicating probable extravasation.

Other design features
This is a Type-1 hybrid effectiveness implementation RCT. A 2-arm, superiority, effectiveness RCT will compare the effectiveness of the IV biosensor with standard observation, to detect extravasations and prevent extravasation injury. Concurrently, a mixed methods study will assess the uptake and attitudinal barriers and facilitators for implementation.

Efficacy
Statistical methods / analysis
Sample size calculations are based on binary expression of extravasation (no harm vs mild, moderate, severe). We conservatively estimate 20% of standard care alone participants will develop any extravasation injury (either mild, moderate, severe) and expect 10% of IV biosensor will develop an extravasation injury. That is, we expect the IV biosensor to have a 50% relative risk reduction in extravasation, compared to standard observation alone. With a=0.05 and power=90%, we are required to record outcome data on 266 participants in each group to detect a between-group difference of this size or greater (total sample=532).
The primary analyses will compare between-groups using a binary logistic regression model with treatment group (IV biosensor + standard observation/standard observation alone) entered as the main effect. Effect estimates will be presented as odds ratio and 95% CI. Secondary outcomes will be analysed using linear regression (continuous data), logistic regression (binary data) or Poisson regression (count data) as appropriate. The cause of any missing data will be assessed, and sensitivity analyses to investigate the potential impact of missingness will be undertaken using multiple imputation techniques if appropriate. Analysis will be ‘intention to treat’ with IVs the unit of measurement (one IV per child only). A per-protocol analysis will assess the effect of protocol violations (i.e. non-randomised IV biosensor). p-values =0.05 will be considered significant.

Estimating cost effectiveness
Regression analysis of the total cost per patient as the dependent variable will be conducted using a generalised linear model with trial group allocation as the predictive variable and controlling possible confounders. A gamma family, log-link model has been assumed given the typically skewed nature of health cost data but will be further tested for appropriate model specification. Cost-utility analysis will be carried out and either the incremental cost per quality adjusted life year gained or net monetary benefit will be calculated based on commonly accepted threshold values of a quality adjusted life year. Probabilistic sensitivity analysis will be used to characterise uncertainty in parameters of the economic evaluation and presented using both a scatter plot and cost-effectiveness acceptability curve. Particular consideration will be given to the potential for cost effectiveness to vary by patient, treatment and other characteristics.

Summary
Brief summary
Many babies and infants admitted to hospital need fluids or medicines delivered directly into their veins using an intravenous (IV) catheter. Over time, IV's can dislodge from the veins and some cases, the medicine or fluid can leak into the child's tissue around the vein, causing damage to the skin, tissue and the vein itself. This is called an extravasation injury. An early sign of extravasation injury is pain, however babies and infants cannot always communicate that the IV site is painful making early detection painful. The IV biosensor is a new device that may help detect extravasation injury sooner. A biosensor is a special light similar to an oxygen saturation probe that is placed on the child's skin above the IV site. It uses near infra-red light to scan the tissues to detect extravasation injury and alerts clinicians so the infusion can be stopped to limit damage caused to the surrounding tissue. This trial will examine whether the IV biosensor helps to detect extravasation injury in babies and infants earlier than compared to standard care. It will also assess whether it is safe and easy to use, and whether it decreases the severity of extravasation injuries.
