In a recent study, Mahendran and colleagues (2021) sought to compare the rates of cochlear implant (CI) referral and implantation across different races and to compare audiometric profiles of the patients via retrospective analysis.
Demographic and audiometric data were collected for 504 patients between 2010–2020 who underwent CI evaluation or implantation. Of those, 388 met CI candidacy criteria and 258 received a cochlear implant. Of those referred for CI evaluation, approximately 69 percent were White, 19 percent were Black and 12 percent were Asian. Interestingly, the institution’s (academic tertiary care institution) service area is 47 percent White, 42 percent Black and 8 percent Asian.
Black patients referred for CI evaluation had significantly worse hearing and word recognition scores than White patients and Asian patients. Black patients who underwent CI evaluation also had significantly worse AzBio scores than White patients.
The authors concluded that Black patients undergo CI evaluation and implantation at rates disproportionately lower than expected based on local demographics. Black patients also have significantly worse hearing at the time of CI referral than White and Asian patients.
Identifying and increasing awareness of these disparities are essential steps to improving cochlear implant access for disadvantaged populations.

Should we provide cochlear implants earlier for children with large vestibular aqueduct syndrome? Patterson and colleagues (2021) examined outcomes of nine pediatric patients with Pendred syndrome who received cochlear implants between 2003–2017. Pendred syndrome is an autosomal recessive disorder defined by the combination of sensorineural hearing loss, goiter and an enlarged vestibular aqueduct (EVA). All…
Cochlear implantation is generally considered a safe and effective recommendation for healthy adults who have bilateral, moderate-to-severe or moderate-to-profound sensorineural hearing loss and do not benefit from acoustic amplification (i.e., poor speech recognition). However, given the large elderly population and the importance of timely hearing intervention, there is a need to more closely examine the…
Do you work with older adults who have both hearing loss and reduced physical functioning? If so, you will want to read a recent article by Martinez-Amezcua and colleagues (2021) who reported a significant association between hearing loss and reduced physical functioning. These authors also reported an association between hearing loss and reduced walking endurance. …
