Protocol for: mixed methods study on diversity of children with cochlear implants and their families engaging with the BEARS (Both Ears) virtual reality training games: improving clinical trial diversity and scale-up inclusiveness
This mixed-methods study protocol outlines a plan to evaluate and improve the sociodemographic diversity of participants in the BEARS virtual reality clinical trial for deaf children with bilateral cochlear implants by analyzing recruitment data, identifying barriers through qualitative research, and implementing targeted interventions to ensure the trial better represents the UK population.

Imagine a world where your ears are like a super-sensitive radio, but sometimes the signal gets fuzzy when there's too much static around you. For many children, doctors can fix this with a tiny device called a cochlear implant, which acts like a digital bridge, sending sound signals straight to the brain. But here's the tricky part: just because a bridge exists doesn't mean everyone can cross it easily. In the world of medical research, scientists often build these bridges, but they sometimes forget to check if the bridge is accessible to everyone—whether that's kids from different neighborhoods, families who speak different languages, or parents who work long hours. If a study only includes kids who live nearby, speak English perfectly, and have parents with lots of free time, the results might look great, but they won't help the kid living far away or the family struggling to make ends meet. This is the big question this paper tackles: How do we make sure medical research includes all kinds of people, not just the ones who are easiest to find?
This paper is a roadmap for a special project called "BEARS" (which stands for Both Ears). The main goal of the BEARS project is to test out some cool Virtual Reality (VR) games designed to help children with cochlear implants hear better in noisy places, like a busy classroom or a loud playground. The scientists want to see if playing these games actually helps, and if it does, they hope to give the games to every child with an implant in the UK. But before they can roll out the games to everyone, they need to make sure the group of kids testing them out is a true mix of the whole population, not just a small, easy-to-reach slice.
Think of the recruitment process like a giant, leaky pipe. At the top, you have all the children in the UK who have cochlear implants. As the water (the children) flows down the pipe toward the bottom (the final group of kids in the study), some of it leaks out. The paper uses a mixed-methods approach—basically, looking at numbers and talking to people—to find out exactly where the leaks are happening. Are we losing kids because their families don't speak English? Are we losing them because the doctors are too busy to invite them? Or are we losing them because the VR equipment feels too complicated or expensive to use at home?
The researchers are currently in the middle of this investigation. They are looking at data from the first six months of the trial to see who signed up and comparing it to the real world. They suspect that certain groups, like families from ethnic minorities, those living in poverty, or those who use sign language, might be getting left behind. To fix this "leaky pipe," they are holding workshops and talking to families who said "no" to the study to understand why. They want to plug the holes so that by the end of the trial, the group of kids playing the VR games looks just like the diverse population of deaf children across the UK. However, there are specific rules for joining the study: children must have received their implants before the age of three (unless they have progressive hearing loss), and those with certain additional needs or unstable implant outcomes are excluded to ensure the results are clear.
The paper doesn't claim to have solved the problem yet; in fact, it admits that finding the right data is hard because some records aren't kept consistently. However, it suggests that by using a "leaky pipe" analogy to track where people drop out, and by listening to the stories of those who didn't join, they can figure out how to make the study fairer. The ultimate goal isn't just to finish a study, but to create a plan for how to share these VR games with every child who needs them, ensuring that the benefits of the research reach everyone, not just the lucky few who fit a perfect profile.
