Summary
Children receiving cochlear implants (CI) in West Denmark show poorer speech and language outcomes compared to East Denmark, despite similar hearing levels. This highlights regional disparities in paediatric CI care.
Area of Science:
- Audiology
- Pediatric Health
- Speech-Language Pathology
Background:
- Universal neonatal hearing screening (UNHS) and bilateral cochlear implantation (CI) were introduced in Denmark.
- Regional differences in outcomes for pediatric CI users were investigated.
Purpose of the Study:
- To examine regional variations in outcomes for pediatric cochlear implant recipients in Denmark.
- To assess the impact of UNHS and bilateral implantation on these outcomes.
Main Methods:
- A cohort of 94 pediatric CI subjects was evaluated.
- A comprehensive test battery assessed audition, speech, language, and self-esteem.
- Fisher's exact test and logistic regression analyzed regional differences and rater variability.
Main Results:
- Auditory levels were comparable between West and East Denmark.
- Significant differences in speech and language outcomes favored East Denmark.
- West Denmark children received more speech therapy and support, with lower parental involvement.
Conclusions:
- Remarkable regional disparities in pediatric CI outcomes exist in Denmark.
- The quality and organization of care in West Denmark require thorough evaluation.
- Addressing these disparities is crucial for optimizing pediatric CI rehabilitation.
