When to consider a cochlear implant evaluation for your client*
Did you know that in New Zealand, approximately 1 in 20 adults who could benefit from a cochlear implant have one?1 If hearing aids are not providing your clients the ability to achieve their listening goals, a cochlear implant may be the next step.
A cochlear implant may be the next step for your client
Cochlear implants are an established treatment for people of any age with moderately severe to profound hearing loss when hearing aids are no longer provide enough benefit.2 Evidence shows that cochlear implants provide access to improvements in the areas of speech understanding, quality of life, cognition, mental health, and well-being.2-15 Research also shows that for people that meet candidacy, earlier implantation is associated with better outcomes.16
A recent study showed that 95% of patients who met traditional indications for a cochlear implant (n=25) had a pure-tone average that was greater than or equal to 60 dB, while 92% had a better ear unaided monosyllabic word score that was less than or equal to 60%. Therefore, patients with hearing losses greater than or equal to 60 dB HL (pure tone average 0.5, 1k, 2 kHz) and speech understanding less than or equal to 60%, should be considered for a referral for a cochlear implant evaluation.17
96% of patients that met the 60/60 referral guidelines were cochlear implant candidates17
Referral guidelines for New Zealand
If your client meets ANY of the criteria below in BETTER ear, consider referring the client for a cochlear implant evaluation to determine candidacy.*,17

If your client meets any of the 60/60 screening criteria, refer your client to the nearest cochlear implant programme.
- If your client lives north of Taupō, refer your client to The Hearing House.
- If your client lives south of Taupō, refer your client to Southern Cochlear Implant Programme..

Did you know?
Many adult cochlear implant users continue to wear a hearing aid on their non-implanted ear, commonly referred to as bimodal hearing. For many people, using a cochlear implant on one ear and a hearing aid on the other is the combination that provides them with their best hearing.
When compared to using a hearing aid or cochlear implant alone, users of bimodal hearing report a more natural hearing experience,18 improved speech understanding in quiet and noise,19-22 improved perception of music,23 and better functioning in real-life environments.19
In a large study, users of bimodal hearing also reported much higher satisfaction with their hearing performance across a range of listening situations, compared to when they used two hearing aids.24
*This provides a recommendation only of when an adult may be referred for a cochlear implant evaluation, but does not guarantee candidacy based on indications. (Only for adults).
