Stroke patients with delirium appear to have unfavorable outcomes when compared with those who do not have delirium, according to a Canadian study. When compared with stroke patients without delirium, those with it had:

Higher inpatient and 12-month mortality rates.
Longer hospitalizations (mean difference, 9.39 days).
A greater degree of post-discharge dependence.

The analysis noted that those with delirium were more likely to be discharged to a nursing home or other institution.
