Importance
Despite the sizeable global burden of hearing loss, cochlear implants have poor penetrance among eligible hearing-impaired individuals. Identifying populations who may benefit from a cochlear implant but among whom penetrance is poor is an important aim in reducing the health-related and economic effects of hearing loss on both individuals and society.
Objectives
To explore the association of socioeconomic status (SES) with cochlear implant candidacy and the decision to undergo cochlear implantation.
Results
A total of 754 individuals underwent candidacy evaluations and were included in the analysis (386 [51.2%] women; mean [SD] age, 64.0 [15.7] years). Of these, 693 (91.9%) were cochlear implant candidates, and 623 candidates (89.9%) underwent cochlear implantation. Multivariable analyses demonstrated that individuals in the highest income quintile had lower odds of cochlear implant candidacy compared with those in the lowest income quintile (odds ratio [OR], 0.26 [95% CI, 0.08-0.91]), and candidates in the highest income quintile had greater odds of undergoing cochlear implant surgery compared with those in the lowest quintile (OR, 2.59 [95% CI, 1.14-5.86]). Living in a small town or a micropolitan or rural area was associated with lower odds of undergoing cochlear implant surgery compared with living in a metropolitan core (OR, 0.18 [95% CI, 0.04-0.83]) after controlling for distance to the primary implant center.
Conclusions and Relevance
The findings of this cohort study suggest that individuals with higher SES are less likely to qualify for a cochlear implant; however, those who qualify are more likely to undergo surgery compared with those with lower SES. These findings highlight a hearing health care disparity that should be addressed through further studies to guide population-based initiatives.
