17Counselling, ethics & informed consent
Candidacy is not only a calculation of benefit; it is a conversation, and an ethical one. A cochlear implant changes how a person hears, communicates and belongs, so the work-up has to weigh more than audiograms: the cultural meaning of deafness — most acutely for a deaf child of Deaf parents, for whom deafness is an identity rather than a deficit — and the patient's own motives and understanding. As candidacy expands into people with learning disability, dementia or multiple disabilities, the apparently routine matter of consent becomes real clinical work, requiring formal assessment of the capacity to understand and agree. And because the device only helps those who use it, honest counselling about what implantation can and cannot deliver is not a courtesy but part of valid consent. This module turns those duties into concrete referral logic.
FDeaf-community ethics
Candidacy includes an explicit cultural step: the team must weigh the medical and the sociocultural views of deafness, rather than treating it purely as a deficit to be fixed. This is most acute for a deaf child of a Deaf family, where the decision touches identity, language and belonging. Respecting that perspective — and ensuring the choice is genuinely the family's — is part of doing candidacy ethically.
CCapacity and informed consent
As candidacy expands, informed consent stops being routine. Candidates with learning disability, dementia or multiple handicaps need a formal assessment of their capacity to understand the procedure and give valid consent, and a qualified interpreter where language requires one. Consent is a process to be supported and documented, not a signature to be obtained.
CThe psychologist and the hearing therapist
Formal psychological assessment has been recommended since the early years of implantation. A severe psychiatric disorder is a relative, not absolute, exclusion, and such patients are hard to identify, so referral is advised for any concern, for non-organic hearing loss, and for questionable consent capacity. Alongside, the hearing therapist runs a holistic real-life assessment — live-voice testing across redundancy levels, a structured interview about everyday areas of difficulty, and quality-of-life, tinnitus and dizziness questionnaires.[1998] A social worker is triggered where support-network or resource barriers exist — psychosocial candidacy turned into concrete referral logic.
CExpectation-setting as consent
Honest expectation management is itself part of consent. Candidates must be told that a small minority — on the order of 3–7% — gain little and cannot be identified in advance; that residual acoustic hearing may be lost; and that effort and rehabilitation are required for the result to come. Setting expectations to the real, gradual trajectory (Module 15) protects against the disappointment and non-use that undo otherwise sound candidacy — which is why it belongs in the consent conversation, before surgery and after.
