Objective: The incidence of post-stroke delirium varies widely from 13% to 48%, but few studies have focused on the effect of delirium on functional outcomes after stroke. The purpose of the present study was to assess the effect of delirium on functional outcomes such as motor skills, balance, cognition, and activities of daily living (ADL).
Methods: 231 new onset stroke patients were enrolled in the study from March 2015 to February 2017 at OO University Hospital. Delirium was diagnosed by psychiatrist according to DSM-V criteria. Baseline demographic and hospital data were collected, and functional data including the Korean version of the Modified Barthel Index (K-MBI), the Korean version of Berg Balance Scale (K-BBS), the Korean version of Mini-Mental State Examination (K-MMSE), the Korean version of the National Institutes of Health Stroke Scale (K-NIHSS), and Screening Tests for Aphasia and Neurologic-Communication Disorders (STAND) were evaluated upon admission and at discharge.
Results: 45 delirium patients were identified among the 231 stroke patients. The mean age of the delirium group was 67.7 ± 12.1 years and 48.9% were male. The length of stay was significantly longer for the delirium group. Right brain hemisphere lesions were dominant, and hemorrhagic stroke was found more frequently in the delirium group. Efficiencies and improvements in K-BBS and K-MBI were significantly higher in the non-delirium group.
Conclusion: Post-stroke delirium adversely affects functional outcomes after a stroke, especially balance, motor skills, and activities of daily living.
