Efficacy of the Buzzy® Device on the Prevention of Health Care Induced Pediatric Pain in a Vaccination Center

Study Overview
=================
Brief Summary
-----------------
In vaccination centers, venipunctures and vaccinations are sources of pain and anxiety in pediatric patients. Prior painful experiences can reduce the acceptance of later health care, hence making it more difficult for both patients and nurses. The topical anesthetic cream (lidocaine, prilocaine) and the non-pharmacological (distraction and relaxation) interventions which are usually used for prevention of procedural pain impose certain constraints on families and on vaccination centers. A distraction and local anesthesia (cold and vibration) based medical device (Buzzy®) could overcome these constraints and could be an interesting alternative for healthcare management in vaccination centers and, in a broader perspective, in other medical services. Research on this device has been scarce to date. Three of them have shown an efficacy of Buzzy® in comparison to the absence of prevention of vaccination and venipuncture induced pain. An ongoing study will assess the Buzzy® device in comparison to a topical anesthetic cream, but will be set in an emergency department context. To date, no study has compared Buzzy® to topical anesthetic cream on healthy children in a vaccination center. The research team has formulated the following hypothesis: the Buzzy® device will allow to get a not lower or an equivalent level of pain compared to the level of pain obtained with the usual topical anesthetic cream. The aim of this study is to evaluate the efficacy of the device Buzzy® on vaccination and venipuncture induced pain in a vaccination center.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Buzzy® device<br>Just before the vaccination or venipuncture the device will be applied on the selected site during 30 seconds and then it will be moved 5 cm above the selected site to make the injection or the puncture. The child will choose if he wants to use the cooling system. | Device: Buzzy® device<br>* Just before the vaccination or venipuncture the device will be applied on the selected site during 30 seconds and then it will be moved 5 cm above the selected site to make the injection or the puncture.

| Active Comparator: EMLAPATCH (lidocaine, prilocaine)<br>The patch will be applied during 1 hour to 1 hour and half before the vaccination or venipuncture, on the selected site.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Faces Pain Scale revised (FPS-r) for children | Pain will be assessed by child using the FPS-r. FPS-r is a tool which has been validated and has been shown to be reliable in intercultural children and adolescents population (4 to 17 years). | Day 0 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Faces Pain Scale revised (FPS-r) for parents | Pain will be assessed by a parent using the FPS-r. FPS-r is a tool which has been validated and has been shown to be reliable in intercultural children and adolescents population (4 to 17 years). | Day 0 | 
| Differential cost of the two strategies compared to the differential pain | Differential cost of the two strategies compared to the differential pain, self-reported by children with the FPS-r. Cost assessment of the two strategies will be made by a micro-costing analysis. The parameters analyzed will be : the strategy used (Buzzy® device or EMLAPATCH), the nurses' time and the time spent by child in the vaccination center. This parameters will be aggregated and will be presented in the form of a cost-effectiveness differential ratio and acceptability curves. | Day 0 |
