Summary
This review examines prediction models for cochlear implant (CI) outcomes. While many models exist for speech perception, their clinical utility for predicting CI success in hearing loss patients remains unclear.
Area of Science:
- Audiology
- Biomedical Engineering
- Otolaryngology
Background:
- Cochlear implants (CIs) offer variable clinical outcomes.
- Predicting patient success with CIs is crucial for managing bilateral hearing loss or deafness.
Purpose of the Study:
- To review existing literature on prediction models for clinical outcomes after cochlear implantation.
- To assess the performance and clinical applicability of these prediction models.
Main Methods:
- Systematic review of studies developing or externally validating multivariable prediction models for CI outcomes.
- Screening of 4,042 references, including nine development and one external validation study.
Main Results:
- Speech perception performance was the primary outcome in development studies.
- Common predictors included duration of hearing loss, preoperative measurements, and etiology.
- Many studies lacked information for clinical risk prediction, and external validation was limited.
Conclusions:
- Numerous CI outcome prediction models exist, but their clinical relevance is often uncertain.
- Further research is needed to enhance the clinical utility of current CI outcome prediction models.
