Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention devices to be used in the study will be the Coolsense® device and Buzzy® device. Coolsense® is fully registered with the Therapeutics Goods Administration (2013) and is a reusable, non-invasive hand-held device that immediately cools and numbs the skin
at the site of injection. Buzzy® is a vibrating handheld device used to help block sharp pain and provide distraction when giving injections to children. A frozen cooling pad (wings) is placed behind Buzzy® before the device is placed on the child's arm.

Participants will be randomised into one of three arms: Arm 1. Coolsense®, Arm 2. Buzzy® (with cooling pads) and Arm 3. Standard Care (distraction using Bubbles). If the participant is randomised to Arm 1., then the Coolsense® device will be placed on the child's arm at the site of injection for a count of 10 seconds. As soon as the device is removed (after the 10 seconds), the immunisation will be given. If the participant is randomised to Arm 2., then the Buzzy® device will be placed on the child/adolescent's arm at the site of injection for a count of 30 seconds. After 30 seconds the device is left on and lifted up the arm and the immunisation given immediately (below the Buzzy device).

The interventions (Buzzy®, Coolsense® or standard care) are used for the first injection only during the episode of care. The Immunisation Nurse will administer the intervention the participant has been randomised into.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be enrolled and randomised on the day of the vaccination via Redcap. Randomisation will be to Coolsense®, Buzzy® with wings or Standard care with an allocation ratio of 1:1:1. Randomisation will be in randomly permuted blocks of variable length. An independent statistician in the Clinical Epidemiology and Biostatistics Unit(CEBU) at the Murdoch Children’s Research Institute (MCRI) will provide the randomisation schedules to the Immunisation Clinic.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be in randomly permuted blocks of variable length via Redcap Software Version 6013.3©2016 Vanderbuilt University.

Efficacy
Statistical methods / analysis
The sample size has been calculated at 492 participants who will be randomly allocated in a 1:1:1 ratio to Coolsense® (n=164), Buzzy® with wings (n=164) and standard care (n=164). This ensures sufficient power to support both primary outcomes. Since the study aims to assess two primary endpoints (1a. and 1.b), generalised Bonferroni-adjustment of p-values and confidence interval limits will be applied in order to warrant a global type I error probability of 5%.

For the primary objective (Coolsense® versus standard care) and based on the results from a previous pilot RCT, we have powered this trial to be able to detect a difference child/adolescent reported VAS of 2.85 points between Coolsense® and standard care (equivalent to a 25% reduction from pain. in standard care - mean = 3.8) We have based our sample size estimate on a SD of 2.7. To detect a mean difference in VAS score of 2.85 point post immunisation procedure with a two-sided significance level of 2.5% and power of 80% with equal allocation to these two arms would require 155 patients in each arm.

Allowing for 5% loss to follow up, we will recruit 164 participants to each arm, therefore 492 in total.

The intention-to-treat (ITT) population will be used in the analyses. Participants will be compared according to the group to which they were randomly allocated, regardless compliance to the device used, crossover to other groups or withdrawal from the study. This approach preserves the prognostic balance in the study arms achieved by randomisation.

The baseline and demographic characteristics of participants, as well as all the primary and secondary outcomes will be presented for each arm using the mean, standard deviation (or medians and inter-quartile ranges for non-normal data) for continuous data and proportions for categorical data.

Primary outcome
Comparisons between Coolsense® and standard care, and Buzzy® with wings and standard care regarding the primary outcome (post procedure child/adolescent VAS score) will be made using linear regression models with adjustment for the stratification variable (10-17 years inclusive) used in the randomization, with presentation of mean differences and the corresponding 97.5% confidence intervals (CIs).

Secondary outcomes
Comparisons between Coolsense® and Buzzy® with wings regarding the post procedure child/adolescent VAS score will be made using the same linear regression model specified for the primary outcome, with presentation of mean differences and the corresponding 95% CI.
Arms comparisons (Coolsense® versus standard care, Buzzy® with wings versus standard care, Coolsense® versus Buzzy® with wings) regarding continuous outcomes (post procedure nurse reported VAS scores, post procedure parent and nurse reported CFS score) will be made using the same linear regression model specified for the primary outcome, with presentation of mean differences and the corresponding 95% CI.
Arms comparisons (Coolsense® versus standard care, Buzzy® with wings versus standard care, Coolsense® versus Buzzy® with wings) regarding dichotomous outcomes (compliance to technique, technique effectiveness and usefulness) will be made using a binary regression model specified adjusted for e stratification variable used in the randomization, with presentation of mean differences and the corresponding 95% CI.

Summary
Brief summary
The aim of the proposed study, 'Minimising Immunisatin Pain in Younger Children (MIPY) is to evaluate the efficacy of two novel devices, Coolsense® (cools and numbs the skin) and Buzzy® (vibration) with cooling pads (wings) versus standard care, and to minimise pain during immunisations in younger (aged 3.5 - 9 years inclusive) children (MIPY). Outcome measures will include 1. Child/adolescent self report of pain using the Wong Baker Faces pain rating scale, 2. Parent assessment of their child's fear/anxiety using the Child Fear Scale (CFS) (Pre and post procedure), 3. Nurse assessment of child's fear/anxiety using the CFS scale (Pre and post procedure) 4. Nurse report of observed pain using the VAS Scale, 5. Parent perception of usefulness of Intervention and Nurse observed compliance with intervention. We estimate it will take up to 6 months to recruit the required number of children for these studies based on 75% uptake of those that meet the inclusion criteria.

The study groups will be assigned randomly by a computer.

It is hoped 492 children will participate in this study, with 164 participants in each group.

Before each child has their vaccine, we will either apply Buzzy® (with the cooling pad) or the Coolsense®device, or use the standard distraction method (blowing bubbles).

Possible outcomes will be reduced pain and fear/anxiety scores and improved patient and family experience of vaccination.
