Objective Cochlear implants (CIs) are a cornerstone of hearing rehabilitation for individuals with severe-to-profound hearing loss, yet they remain underutilized among eligible adults. Social determinants of health (SDOH) describe the nonmedical factors shaping health outcomes, including the conditions in which individuals live, work, and age, as well as broader influences like social norms and economic policies. These factors likely contribute to the disparity in CI utilization.
