Prevalence and Risk Factors of Delirium Among Stroke Patients

Background Delirium is a common but often underdiagnosed neuropsychiatric syndrome among hospitalized patients, particularly in those with acute neurological conditions such as stroke. Post-stroke delirium (PSD) is associated with prolonged hospital stays, increased mortality, and poorer functional outcomes. While previous studies have explored various risk factors for PSD, findings remain inconsistent across populations and clinical settings. This study aims to investigate the prevalence of delirium among stroke patients and to analyze its risk factors. Methods From October 2023 to July 2024, a total of 281 stroke patients from the Neurology and Neurosurgery Departments of Guizhou Provincial People's Hospital were selected using a convenience sampling method. The Confusion Assessment Method for the ICU (CAM-ICU) was used for delirium diagnosis. Results The overall prevalence of post-stroke delirium (PSD) was 20.28% (57/281). Stroke type, smoking, alcohol consumption, NIHSS score, WBC count, and the presence of physical restraints were identified as risk factors for PSD, while hemoglobin (Hb) served as a protective factor. Conclusions The prevalence of PSD in this study was relatively high. Nursing staff should consider these factors in stroke patient care and take proactive preventive measures to reduce the occurrence of PSD. Clinical Trial Registration: Not applicable.
