Setting and Study Period: This study is a randomized controlled trial and will be conducted in the Emergency Department of the Stollery Children's Hospital (SCH). The SCH is a tertiary care hospital in Edmonton, Alberta whose annual ED census is \>50,000 children. Based on our team's previous successful work in this field,12 months of patient recruitment is anticipated, and projected to occur from February 2017 to January 2018.

Study Population: The study will include children aged 6-11 years attending the SCH ED, and requiring an IV placement. See Eligibility section for detailed inclusion/ exclusion criteria. We plan to recruit 80 patients, overall.

Recruitment: Research Assistants (RAs) will be on shift from approximately 15:00 to 23:00 seven days a week. This time corresponds with peak visits requiring IV placements based on data collected from previous studies conducted in the SCH ED. RAs will identify and approach patients aged 6-11 years who require an IV placement. Inclusion/ exclusion criteria will be further assessed, and if the child is eligible, the RA will explain the study and invite the parent and child to participate. After obtaining written, informed consent from the parent (and assent from the child, if applicable), the RA will randomize the patient into one of two study arms and begin data collection. The RA will ask one parent/ caregiver for each child to participate and complete all relevant questionnaires.

Study Assessments: After consent/ assent has been obtained, the RA will collect information from the parent on baseline demographic variables (ex. age, gender), presenting signs and symptoms (ex. chief complaint), as well as previous history with ED visits and IV placement. Before the procedure, the RA will bring the MEDi (Medicine and Engineering Designing intelligence) robot into the room for children in the distraction group, set it up, and explain how to interact with it. The staff nurse will then perform the routine set up for IV placement. Pain will be measured using the child's self-reported scores on the Faces Pain Scale Revised (FPS-R). These scores will be collected immediately before and after IV placement has occurred. The child's response behaviors to pain will be assessed using the Observational Scale of Behavioral Distress (OSBD). The procedure and child will be video-taped during IV insertion to complete the OSBD scoring. Parental anxiety will be measured pre and post procedure with the State Trait Anxiety Inventory - State Scale Revised Version (STAI-S, Form Y). The degree of the child's engagement with the robot will be measured immediately following the procedure with the Intrinsic Motivation Inventory (IMI). Additionally, vitals will be collected pre, post and during the procedure. Data will be entered in real-time into a secure online database hosted on REDCap (Research Electronic Data Capture).

Randomization, Allocation and Blinding of Study Treatment: Randomization will be determined using a secure online randomization tool, through REDCap, and hosted via the Clinical Research Informatics Core at the University of Alberta. A trained RA will obtain the computer-generated randomized assignment after child and parent consent/assent has been obtained. Allocation will be concealed from the research staff, ED staff, and participants until after consent and randomization has been assigned by computer. Due to the nature of the intervention, it will not be possible to blind the children, parents, RAs, or ED staff. The children and their parents will be informed that the study is to evaluate different forms of distraction but will not know the study hypothesis for the MEDi robot. The data analyst will be blind to treatment assignment through the use of randomization codes that will not identify groups until analysis is complete.

Study Intervention and Comparison: The intervention will be the use of the MEDi robot. The robot will be at the child's eye level, and will be programmed to introduce itself, interact with the child, and make encouraging comments about how brave he/she was. The duration of its actions will coincide with the length of the procedure (approximately 5-8 minutes). The control group will receive standard care, which generally includes the use of topical anesthetic cream. This comparison is based on the pragmatic preferences of physicians at the Stollery Children's Hospital as well as precedent in the literature.Overall, it is felt that any new intervention (e.g., the MEDi robot) should be compared to what is currently in practice (i.e., standard care), as no single distraction therapy is consistently and routinely employed in EDs at this time.
