Plain English Summary

Background and study aims
Deafness is the most frequent human sensory deficit. Cochlear implantation is the primary intervention. Currently, over 6000 people have bilateral cochlear implants (CIs) in the UK, and most of these are children. Two implants are supposed to provide better access to sound, but it is challenging to interpret and integrate what is heard from both sides. The 'Living with cochlear implants' Patient and Public Involvement group reported that everyday communication is challenging and tiring, with extra effort required to integrate information from two ears, especially in noise. They reported that current rehabilitation techniques are not engaging, or appropriate to their lifestyles. To address these issues, researchers have developed a set of virtual reality games called BEARS (Both EARS). BEARS trains sound localisation and listening in noise. These are skills required in everyday listening. The aim of this study is to determine whether using the directional listening training delivered through the BEARS training package for 3 months alongside usual care compared to only receiving usual care improves speech-in-noise perception, hearing experiences, vocabulary and quality of life and reduces listening effort in young people between 8-16 years old (inclusive) with two CIs. The study will be carried out in clinical CI departments in NHS or University hospitals.

Who can participate?
Patients aged 8-16 years with severe/profound bilateral hearing loss who use bilateral cochlear implants

What does the study involve?
Participants will be randomly allocated into one of two groups:
1. Receive the BEARS training package to use for 3 months alongside usual care. This group will be given a head-mounted display or iPad with the BEARS training package pre-installed. The participants will be asked to complete the BEARS training package for a minimum of 2 x 30-minute sessions a week during the 3 months and also complete a training diary and answer some questions about the BEARS training package on a weekly basis.
2. Continue with usual care
All participants will complete hearing assessments and questionnaires before completing the 3-month intervention. They will be followed up for the next 9 months through online and in-person appointments. Participants and clinicians can also consent to interviews.

What are the possible benefits and risks of participating?
Participants who receive the BEARS training package of virtual reality games will be given training separate to usual care, which is hoped will develop and improve their hearing ability.
The BEARS training package will be carried out using either an Oculus virtual reality head-mounted display or an iPad with headphones. Both devices are licensed for everyday use. There are risks associated with using the Oculus virtual reality head-mounted display, which are detailed in the device’s safety manual on the Oculus website. The main risk associated with this trial and using the Oculus device is falling while playing the games. For this reason, all participants must play the games whilst sitting down on a chair.

BEARS Program Development Grant (PDG)
Some people may find it hard to take part in research, especially if they are from a minority community or feel excluded for other reasons. We want our research results to apply to everyone, so we want to make sure that the people who take part are similar to the population as a whole. We have an additional Program Development Grant from NIHR to look at how diverse the children involved in BEARS are, and how we can improve this.

PDG Work plan
We will look at the children who have agreed to take part in the first 6 months of BEARS and see if they are similar to the UK population of deaf children with implants. We will look at their ethnicity, socioeconomic status, home language, sex, number of siblings, and parent/carer educational level. However, first we will need to look at lots of different information sources to find out about the diversity of deaf children in the UK, as this is not known at the moment. We can then compare with the children recruited to BEARS and see which groups are not being included. We will hold a workshop for the BEARS team and the clinicians at the participating centres to plan how to make recruitment fairer for the rest of the trial. We will then interview children and parents who chose not to take part in BEARS and find out what put them off. We will also talk to clinicians, teachers and other family representatives to ask their opinions on what makes it difficult to be involved in BEARS. We can then plan to make the BEARS NHS roll-out after the trial more inclusive. We hope this may also help other researchers to include a more diverse population of families with deaf children in future.

Scientific titleA Phase III, unblinded, multi-centre randomised controlled trial to evaluate whether 3 months of spatial-listening training delivered via the Both EARS training package (BEARS) in addition to Usual Care compared to Usual Care alone improves hearing abilities and quality of life and is cost-effective in older children and teenagers with bilateral cochlear implants
Study acronymBEARS
Study hypothesisThe overall aim of the BEARS clinical trial is to determine whether using the spatial-listening training delivered via the BEARS training package for 3 months alongside usual care compared to only receiving usual care improves Speech-in-Noise perception, hearing experiences, vocabulary and quality of life in young people with bilateral cochlear implants.

ConditionSpeech-in-Noise outcomes in older children and teenagers with bilateral cochlear implants
InterventionParticipants will be randomized using Sealed Envelope, which is an online software application.

Intervention: Both EARS training package (BEARS) and Usual Care:
BEARS is a compilation of virtual reality games designed specifically for young people with bilateral cochlear implants. The hardware is either: a head-mounted display device or an iPad with headphones. The BEARS training package comprises of three games addressing different hearing functions: speech-in-noise perception, music listening and sound-source localisation. Each game is based on an audio-visual task performed through a virtual-reality interface. Players are guided through on-screen visual prompts to support the gameplay with feedback given on their performance and progress through levels of increasing difficulty. The BEARS training package design allows for the training to be self-administered and played anywhere and at any time. There is no upper limit to the frequency of use of the BEARS training package, it is advised to play the games for a minimum of 1 hour a week over a minimum of 2 x 30-minute sessions, all three games will need to be played.

Usual Care:
This is an annual review appointment with the patient and their clinician. This could be face-to-face, virtual video consultation, questionnaire, or cochlear remote care checks. As a minimum this review will check the following: microphone covers changed, reported or recorded device use, all external and internal equipment working (known through no reported or recorded degradation in hearing ability). During the appointment, the clinician would establish if there were any concerns regarding the cochlear implant functioning and the patient's rehabilitation programme. They will then make any repairs or adjustments to the device and manage additional support and contact as required. Between the annual review appointments patients can attend the implant centre for repair appointments or have spare equipment posted. There is no limit to the level of contact between the patient and the implant centre.

All participants will complete hearing assessments and questionnaires before completing the 3-month intervention. They will be followed up for the next 9 months through online and in-person appointments. Participants and clinicians can also consent to interviews.
