Insights
Identifying factors influencing pediatric cochlear implant (CI) outcomes is crucial. Key factors for auditory and speech performance include hearing loss type, device usage, communication mode, therapy attendance, and family support.
Area of Science:
- Audiology
- Speech-Language Pathology
- Pediatric Medicine
Background:
- Cochlear implant (CI) outcomes are influenced by numerous factors.
- Standardized assessments for auditory and speech performance in CI users vary globally.
Purpose of the Study:
- To identify factors associated with pediatric cochlear implant outcomes within a specific local context.
- To understand the relationship between various factors and auditory/speech performance in children with CIs.
Main Methods:
- Retrospective analysis of 18 factors including audiological, CI team, speech therapy, and family-related variables.
- Utilized Categorical Auditory Performance II (CAP-II) and Speech Intelligibility Rating (SIR) for outcome measurement.
- Employed Kruskal-Wallis H Test and Fisher Exact Test with a significance level of p < 0.05.
Main Results:
- Significant associations found between post-CI CAP-II and hearing loss type, hearing aid usage, communication mode, attention, therapy attendance, and siblings.
- Significant associations identified for post-CI SIR with hearing aid usage, attention, communication mode, therapy attendance, initiatives, and siblings.
Conclusions:
- Factors influencing CI outcomes are multifaceted and dynamic.
- Some factors demonstrated clear associations with auditory and speech performance, while others did not replicate findings.
- Further prospective research is recommended to refine the understanding of individual factor impacts.
Introduction:
Many factors are associated with cochlear implant (CI) outcomes and various methods of assessment for auditory and speech performance outcomes in CI are available globally. The objective of this study is to identify factors relating to CI outcomes in paediatric population that suits local context.
Materials And Methods:
A total of 18 factors consisted of variables which emphasise on audiological, CI service team, speech therapy, and family-related factors. These factors were then retrospectively analyzed among CI recipients. The outcome measurements of categorical auditory performance II (CAP-II) and speech intelligibility rating (SIR) were used to individually study each factor. Kruskal-Wallis H Test and Fisher Exact Test used with p-value <0.05 were considered significant.
Results:
There were significant associations between post- CI CAP-II with type of hearing loss, hearing aid usage per day and mode of communication, attention, attending audiology and speech session, and siblings. For post-CI SIR, hearing aid usage per day, attention, mode of communication, attending audiology and speech session, initiatives, and siblings were statistically significant.
Conclusion:
The factors affecting the outcome of CI are dynamic. Some of the factors have demonstrated to be associated with the auditory and speech outcome in CI recipients while some factors failed to replicate similar findings. Further prospective research may refine the outcome of individual factors.
