Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Preoperative anxiety is frequently experienced by children undergoing anaesthesia and surgery and being separated from parents during the operation. It is associated with a significant number of adverse outcomes such as maladaptive behavioural changes and increased postoperative analgesic requirements. Pharmacological interventions such as midazolam are widely used to decrease preoperative anxiety in children. However, premedication may be associated with undesirable effects such as paradoxical reactions, prolonged sedation and adverse behavioural changes.The aim of this study is to develop and use a serious game, HospiAvontuur, which can be used during the preparation of children for an admission at the hospital. By using this game the researchers aim to reduce the usage of pharmacological interventions and to increase the use of non-pharmacological interventions, such as HospiAvontuur.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The research questions for the primary outcome are formulated in 5 zero hypotheses:

Zero hypothesis 1: there is no difference in anxiety levels measured as mYPAS-SF on T1 between the two groups.

Zero hypothesis 2: there is no difference in anxiety levels measured as mYPAS-SF on T2 between the two groups.

Zero hypothesis 3: there is no difference in anxiety levels measured as ICC on T2 between the two groups.

Zero hypothesis 4: there is no difference in anxiety levels measured as VAK 4-12 on T0 between the two groups.

Zero hypothesis 5: there is no difference in change in anxiety levels measured as difference between mYPAS-SF on 2 moments (T1 versus T2) between the two groups.

The research questions for the secondary outcomes are formulated Zero hypothesis 6: there is no difference in level of emergence delirium (ED) measured during the postoperative period (T3) in the recovery room, at 4 moments, as PAED scale, between the two groups.

Zero hypothesis 7: there is no difference in level of postoperative pain measured during the postoperative period in the recovery room, as FPS-R scale and OPS scale, between the two groups.

Zero hypothesis 8: there is no difference in level of pain as FPS-R scale and problematic behaviour (PB) as modified and simplified version of the PHBQ questionnaire on day 2 and at the end of week 1 after the operation.

Design The design of the study will be a single blinded randomized clinical trial. Children will be divided in 2 research groups: an intervention group (children who will play the game HospiAvontuur as a non-pharmacological at home preparation prior to the hospital admission. These children will not receive any pharmacological preparation - Midazolam - at the hospital) and a control group (children who do not play the game at home and do receive a pharmacological preparation - Midazolam - at the hospital). Participants will be randomly assigned to the intervention group or the control group using a computer-generated random allocation sequence, created by the study investigator (F.V.). Each patient will receive a unique randomized test number.

Outcome measures As primary outcome for this research project, 2 kinds of anxiety will be measured. First the trait anxiety will be measured. Therefore the VAK 4-12 (Vragenlijst Angst Kinderen - attachment 1) will be used. To measure the state anxiety, the mYPAS-SF and the ICC will be used.

Emergence delirium: ED will be measured in the recovery room, using the five-point Pediatric Anesthesia Emergence Delirium Scale (PAED).

Pain will be measured in the recovery room, using the four-point Objective Pain Scale (OPS), at two time moments: the time of the first awaking of the child and the moment of discharge from the recovery room. For the purpose of this study, the FPS-R (Faces Pain Scale - Revised), a self-reporting pain scale, will also be used on the same time moments. This instrument will be used by a researcher.

On two time moments: 2 days after surgery and at the end of the first week after surgery, parents will receive a phone call from one of the doctors from the anesthesia department or the study investigator.

Both postoperative pain and problematic behaviour will be questioned during a semi-structured interview. The FPS-R will be used for pain measurement and 10 questions will be asked in order to get a good impression of the child's postoperative behaviour (table 1).

One version of the FPS-R will be handed over to the parents and the child at the moment of discharge from the hospital. Parents will be informed that they can expect a phone call from a researcher or an anesthesia staff member and that some questions including the pain perception will be asked.

Power analysis

Based on the duration of the research project, the expected subjects that could be included in the study, the controlling of the variables and based on previous research from Marechal et al (2016), the following power analysis was calculated:

A total research population of 164 subjects (82 subjects per group), would be required to demonstrate a 8 point difference in m-YPAS score at time of induction (level of significance of p \< 0.05 and power of 80%). The mean mYPAS score at time of induction, after MDZ premedication in the study of Marechal et al (2016) was 43.74 (SD = 18.32).

Data received from the OR database (1/12/2015 - 30/11/2016) show that approximately 300 children undergo ORL surgery over 12 months. Our study will start at 01/09/2017 and will end on 31/05/2018 (a period of 9 months). During this period approximately 225 children will be operated in the OR. As surgeons are able to set parents at ease to participate in the study because no harm will done to the child and since children nor parents won't notice the presence of the researcher in the OR (performing the observations), it is expected that most parents and children will participate. However, some parents are not keen on scientific studies. Others will not be interested in participating because their mind is set on the child that needs surgery rather than on other things. Moreover, the number of children undergoing ORL surgery is not always constant and there is also a risk of loss-to-follow-up. Therefore, the sample size of 164 patients will be inflated to 90 participants per group (180 in total) to account for a possible 10% loss-to-follow-up.

Statistics The significance of the differences between the two groups for the scores of VAK4-12, mYPas at T1, mTPAS at T2, ICC will be tested with Mann-Whitney U-tests. The significance of the differences between T2 and T1 for the two groups will be measured with two-way ANOVA. All statistical analyses will be done in the package SAS.

Ethics During the recruiting of the participants it is important that both parents and children are fully informed about the randomization process. In general, playing a serious game is considered to be a pleasant activity and children who are assigned to the intervention group may consider themselves to be lucky. On the other hand parents may think that playing a game and therefore not receiving the standard pharmacological treatment may be considered as unfavourable. When providing information to parents it is crucial to make it clear that both the non-pharmacological as the pharmacological strategies have a scientific basis and that no harm will be done to the children.

The non-pharmacological preparation of children before surgery is considered standard procedure in many hospitals. At the Jessa Hospital this is not yet the case although questions about this issue have been risen some time ago, according to the anaesthesia department. At this moment there is no specific non-pharmacological alternative in use. Therefore this research project could be an answer to this issue. The results from the study could support the decision in whether a non-pharmacological preparation program could be introduced.

During the observations of the children in the preoperative holding area and in the operating room during anesthesia induction, it is possible that the researcher or the anesthesiologist can happen to hear some information from the child or the parent about gaming experiences. This can be the case when the child recognizes specific information in the OR that he/she has experienced during the gameplay. When this is the case, the researcher and/or the anesthesiologist should make a remark on the observation form. Even if this is the case, the objective observation and scoring on the scale should continue as planned.

The design of the study will be a single blinded randomized clinical trial. Children will be divided in 2 research groups: an intervention group (children who will play the game HospiAvontuur as a non-pharmacological at home preparation prior to the hospital admission. These children will not receive any pharmacological preparation - Midazolam - at the hospital) and a control group (children who do not play the game at home and do receive a pharmacological preparation - Midazolam - at the hospital).

Each patient will receive a unique randomized test number.

Primary Study Purpose

PREVENTION

Blinding Strategy

TRIPLE

Caregivers Investigators Outcome Assessors

Two sets of cartboard boxes will be prepared. The boxes are prepared and numbered by the study investigator (F.V.) (the unique randomized test number) and distributed amongst the consultation offices of the surgeons by the researchers. To blind both the researchers and the surgeons, the 2 sets of boxes will have the same weight. The weight of the ipad is simulated in the boxes of the control group by the use of a coloring book. This will prevent patient selection bias.

After the consultation and when the parent and the child has agreed to participate, the surgeon hands over a box to the parent. The surgeon writes the box number, name of the child, date of birth and the phone number of the child in an excel sheet. This document will be used during data procession.

The patients participating in the trial, the treating physicians, the surgeons dispensing the study boxes, the researchers assessing outcomes and the data-managers will be blinded for group allocation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

HospiAvontuur

Intervention group - Non-pharmacological (HospiAvontuur) preparation HospiAvontuur is a simple point and click adventure game on a I-pad. The game describes the pathway which a child and his parents will take before, during and just after a hospital admission for an elective otorhinolaryngeal procedure under general anaesthesia.

Group Type EXPERIMENTAL

HospiAvontuur

Intervention Type DEVICE

To be included in the study children should play the game at least one time together with one parent

Midazolam

control group: The children of the control group will not play the game HospiAvontuur as an at home preparation for surgery. These children will be prepared for surgery according to the current practice at the Jessa hospital. Children receive only the basic information during the consultation with the surgeon. There is no specific at home preparation required. When admitted at the hospital, children receive a pharmacological preparation, 45 - 60 minutes prior to the induction of the anaesthesia. The medication is administered orally by a small syringe in the mouth and contains Dormicum 0.3mg/kg body weight and atropine 0.02mg/kg body weight supplemented with raspberry syrup.
