The British Cochlear Implant Group (BCIG) has published a referral guide which is available to any audiologist who may see patients with a hearing loss that could potentially benefit from a cochlear implant.
It includes referral criteria, details of how you should refer and what information is required about the patient, along with a link to Cochlear Implant centres across the UK.
You can download (and print) the poster here or contact the BCIG for a laminated version.
