Evaluation of interactive videos to enhance benefit for new hearing aid users - HEAR IT

Background and rationale
Hearing aids have the potential to transform the lives of those with permanent hearing loss, yet out of the two million people who have one, around 20 percent – 400,000 people – do not wear their device. Hearing aid non-usage can result in continued difficulties in communication in everyday situations, which can lead to social isolation and withdrawal, and reduced overall quality of life.
As hearing aid follow-up appointments are not routinely offered to everyone in the UK, all the important information often needs to be given at the time of the hearing aid fitting. As such, interactive multimedia videos (or reusable learning objects, RLOs) offer advantages in that they can provide essential and supplementary information, be used at a time that suits the user, used as many times as the user wants and needs, and can be delivered remotely in the home environment.
This project developed a series of RLOs (total duration 1 hour) to explain many of the issues around using hearing aids. The aim of the study was to supplement advice from audiologists and see whether hearing aid users would get more benefit from their hearing aids when they watched the RLOs.
The content of the RLOs was based on principles of learning theory and were developed in collaboration with over 35 hearing aid users to ensure they engaged the targeted audience and provide optimal learning. Each self-contained RLO was structured with learning outcomes, multi-media (videos, photos, animations), and an interactive self-evaluation quiz, as well as powerful testimonials, anecdotes and humour. All RLOs were subtitled.
We completed a randomised controlled trial involving 203 first-time hearing aid users to assess how effective the RLOs were in helping people to get the most out of their hearing aids. In the study, the RLOs were delivered via DVD for TV and PC, and the Internet.
There were a total of seven RLOs (plus an introduction) which covered the following topics:
- Getting to know your hearing aids
- How to insert your hearing aids
- What to expect when wearing hearing aids
- Adapting to wearing your hearing aids
- Communication tactics
- Using the phone and other devices
- Hearing aid care and troubleshooting
Hearing aid users who got the videos at the same time as their hearing aids had significant benefits compared to those who only got hearing aids. These benefits included:
- Better knowledge of hearing aid-related issues
- Better hearing aid handling skills
- Greater use of hearing aids for people who didn’t wear their hearing aids all of the time
- Improved confidence and reassurance in using hearing aids and communicating
- In addition, the RLOs were rated highly useful by hearing aid users and audiologists
- Take-up and adherence was also very high

The success of this research is attributable to the high level of participation by patients and professionals (from NHS Audiology, private sector, hearing-aid industry and charities) at all major stages.
“From ancient scripts to live video conversations, the art of communication and passing on a message has taken many different forms, but up until now information surrounding hearing aid management has relied on either face to face information giving or written text. It is therefore exciting to be involved in the production and use of an interactive video tool for passing on information. Informative, constructive and easily accessible, I cannot wait for the product to be available to all patients issued with an NHS hearing aid.”Karen Advanced Audiologist
“If I did not have the DVD I might have given up wearing my hearing aids. Because of the DVD I have entered a much easier self-directing and informative environment, instead of a wild woolly and noisy world. I think the DVD is a well thought out educational resource.”Hazel Participant
“Everyone should have access to the video tutorials in some form or another’. Her friend who was fitted with hearing aids 10 days later, frequently contacted her for advice enquiring ‘What does the video say?”Isobel Participant
