Of note, although speech-language pathologists (SLPs) do not diagnose delirium, SLPs may administer delirium screening tools as part of a multidisciplinary effort to prevent and manage delirium.</div>

<div>Limitations of this review include the small number of included studies. Additional research is needed to investigate the accuracy of the DOS across various clinical settings and populations.</div>
