As age increases, the prevalence of hearing loss significantly increases, reaching up to 89% of those 80 years and older.

Hearing loss during hospitalization increases the risk of misdiagnosis. There is a lack of empirical data regarding prevalence and recognition of hearing loss in hospitalized older adults. In this article, we describe a variety of negative outcomes that may result when older inpatients are functioning with unrecognized hearing loss.
