Insights
Cochlear implants (CIs) benefit children with complex needs, showing improvements in auditory skills. However, outcomes were less significant than in children without complex needs, suggesting a need for tailored assessments.
Area of Science:
- Audiology
- Pediatric Otolaryngology
- Speech-Language Pathology
Background:
- Cochlear implants (CIs) offer significant auditory and speech benefits.
- Outcomes for children with complex needs receiving CIs are less reported.
- Assessing CI efficacy in this population requires specific considerations.
Purpose of the Study:
- To evaluate the assessment and outcomes of children with complex needs who received cochlear implants (CIs).
- To compare CI outcomes in children with complex needs against a control group without complex needs.
Main Methods:
- A prospective review of 19 children with complex needs undergoing CI surgery.
- Pre- and 12-month post-implant assessments using audiology, Categories of Auditory Performance (CAP), Meaningful Auditory Information Scale (MAIS), Listening Progress (LiP), and Meaningful Use of Speech (MUSS) scales.
- Comparison with 230 children without complex needs at the Yorkshire Cochlear Implant Service (YCIS).
Main Results:
- Children with complex needs showed improvements in CAP, MAIS, LiP, and MUSS scores post-CI.
- Improvements were less pronounced compared to the control group without complex needs.
- For example, LiP scores improved from 11% to 65% in the complex needs group versus 22% to 81% in the control group.
Conclusions:
- Cochlear implants provide benefits for children with complex needs, though outcomes are less than in typically developing peers.
- Standard outcome measures may not fully capture the benefits for this group.
- Quality-of-life measures should be considered alongside communication development to reflect the true impact of CIs.
Objectives:
Prospective review of the assessment and outcomes of children with complex needs receiving cochlear implants (CIs) at the Yorkshire Cochlear Implant Service (YCIS).
Methods:
Nineteen children with complex needs were assessed pre-implant and 12 months post-implant switch-on using appropriate developmental-related audiology, categories of auditory performance (CAP), meaningful auditory information scale (MAIS), listening progress score (LiP), and meaningful use of speech scale (MUSS). Outcomes were compared with 230 children at the YCIS without complex needs.
Results:
Average CAP scores improved from 0.4 to 3.0, compared with 4.2 in the control group. MAIS scores as completed by parent and teacher improved to 62 and 57%, respectively, compared with the control group who achieved 82 and 70% at 12 months. LiP scores improved from 11 to 65% compared with the control which increased from 22 to 81%. MUSS scores as assessed by parent and teacher improved to 35 and 31%, respectively, at 12 months compared with 52 and 51% in the control group.
Discussion:
CIs in children have been shown to be cost effective and provide benefits in auditory and speech perception; however, there are few reports specifically relating to outcomes in children with complex needs. Improvement was seen across all outcome measures although less than in children without additional needs. Consideration should be given to the use of quality-of-life measurements as the development of oral communication may not be a realistic goal or accurately reflect benefits gained by the use of CIs in this patient group.
