Cochlear implantation in adolescents: Factors influencing compliance

Abstract

ObjectivesTo quantify rates of non- and partial-use of cochlear implants (CIs) in adolescent patients implanted in adolescence and childhood and identify factors influencing compliance.MethodsA retrospective case note review undertaken at The Manchester Auditory Implant Centre. Adolescents were defined as young people aged 11–18 years. Individuals implanted in adolescence were defined as Group 1, individuals implanted in childhood under the age of 3 years and currently adolescents were defined as Group 2 and individuals implanted between the age of 3 and11 years and currently adolescents were defined as Group 3. Non-use was defined as not using the CI at all and partial use was defined as consistently using the CI less than full-time, or fluctuating periods of full and less than full-time use.ResultsIn Group 1 there was 1 non-user (1.3%) and 11 partial-users (13.9%), with an overall non-compliance rate of 15.2%. In Group 2 there was one non-user (1.9%) and one partial-user (1.9%) with an overall non-compliance rate of 3.8%. In Group 3 there were no non-users and eight partial-users (9%), with an overall non-compliance rate of 9%. The factors influencing compliance differed between groups with the most common factor in Group 1 being a preference for the auditory input gained from the contralateral hearing aid (50%). In Groups 2 and 3 the main factors influencing compliance were behavioural and related to wearing the implant only at school (50 and 75%, respectively).ConclusionsPatients implanted during adolescence have higher rates of non- and partial-use compared with their adolescent counterparts who have been implanted during childhood. It is important to investigate factors influencing non-compliance so appropriate support may be provided to the patient and their family.
