Expanding markets around the world

Over 750,000 cochlear implant users worldwide

Technology is efficient, effective, reliable, ever-improving Abundant research findings on impact of CI, beyond hearing, speech & language‌executive function, improved theory of mind

Our first generation of CI children have grown up and realized academic and vocational goals commensurate with hearing peers

Mounting evidence of the role of hearing in reducing effects of ageing, dementia and improving the quality of life

Global burden of hearing loss • Hearing loss is one of the leading causes of overall disability worldwide • Globally, approximately 466 million adults and children (6%) have a disabling hearing loss

900

• This is projected to rise to 630 million by 2030 and to over 900 million by 2050

• Hearing loss has a substantial impact on people’s lives (e.g. communication difficulties and reduced well-being1)

What do we know?

Benefits have been demonstrated but adoption is low

Delphi consensus process and achieving standard of care Report of clinical evidence and expert opinion on cochlear implantation in adults Findings from the Delphi process have the potential to: o help establish CIs as the standard of care for adults with severe to profound SNHL o raise awareness of CI as a treatment option and when it should be considered o achieve appropriate improved access to CIs for patients who would benefit o help optimize patient pathways, leading to treatment that improves the individual’s hearing function and quality of life 5

Review of immunisation records of 135 Cochlear implant recipients over the last 5 years New Zealand Medical Journal 13 March 2020 Vol 133 No 1511

Results

• 62.2% had influenza vaccination

• 29% had received the PCV 13 vaccine • 40% had received the 23 PPV • 14.8% received a full pneumococcal immunisation schedule • 11.9% had received HiB immunisations

Summary The vaccination rate of CI patients implanted by the Northern Cochlear Implant Programme in New Zealand is low There have been no cases of meningitis post CI in this population Full funding for vaccination for cochlear implant recipients was included in the 2017 revision of guidelines by the Immunisation Advisory Centre http://www.immune.org.nz/hot-topic/fundedvaccines-special-groups-1st-july-2017

Increased awareness about vaccination for cochlear implant recipients in New Zealand is needed

Nicole Zhao MAud Master’s Thesis Electroacoustic Hearing: An exploratory study into the candidacy and benefits of electroacoustic devices in New Zealand

Electro-Acoustic Stimulation (EAS)

Part 1: Questionnaire of NZAS Audiologists knowledge of EAS and current fitting practices of individuals with steeply sloping HL Part 2: Review THH recipients who could be a candidate for EAS Records for 382 individuals aged 19 and above with a N6 or N7 processor Only 12 were identified as fulfilling pre-operative audiometric criteria of thresholds <70dB HL at 250-750Hz. One adolescent recruited- Case Study

Summary and Conclusions • Limitations in knowledge of EAS candidacy has been demonstrated in New Zealand audiologists.

• While audiologists are aware of what EAS is, they may not refer candidates until residual hearing is too poor to take advantage of the technology. This is likely a reflection of restricted

funding and stringent criteria for CI consideration in adults, resulting in limited exposure and awareness of EAS. • For this recipient, use of EAS compared to the electric only program yielded improvements in speech perception outcomes in noise • Greater awareness of CI candidacy to include the population who could benefit from EAS could result in more referrals and potentially better client outcomes with hearing technologies in general.

Support Research at THH and NCIP Research helps us understand the impact of hearing loss and how to best use technologies and/or practices to overcome its consequences.

Research may sometimes be perceived as being time consuming and invasive.

Indeed, it can require extra time and effort but it also offers everyone an opportunity to contribute to the expanding pool of knowledge. Participation is voluntary and â&#x20AC;&#x153;giving backâ&#x20AC;? is always appreciated.

The Hearing House has a special alliance with the University of Auckland and the centres for research within its domain. In addition to sharing personnel resources, there is a mutual focus on collaboration for research. As these projects progress, we will be inviting The Hearing House family to participate as able and as interested.
