Randomized Controlled Trial Multicenter StudyAssociation between psychomotor activity delirium subtypes and mortality among newly admitted post-acute facility patients.
Delirium is common among hospitalized elders and may persist for months. Therefore, the adverse impact of delirium on independence often occurs in the post acute care (PAC) setting. The effect of psychomotor subtypes on delirium remains uncertain. The purpose of this study is to examine the association between psychomotor activity delirium subtypes and 1-year mortality among 457 newly admitted delirious PAC patients. ⋯ All three psychomotor disturbance subtypes had an elevated risk of dying during the 1-year follow-up relative to the normal psychomotor group, though the hypoactive group had the highest mortality risk and was the only group with a statistically significantly elevated risk relative to the normal group.
