Incidence and risk factors for post-stroke delirium in the elderly: A national inpatient sample (NIS) analysis.

ABSTRACT:

Background

Post-stroke delirium (PSD) is a critical neuropsychiatric condition affecting up to 50% of elderly patients during hospitalization, often leading to poorer outcomes. Despite its prevalence, PSD remains underrecognized in clinical practice, and national-level studies exploring its risk factors are limited.

Objective

To examine the incidence and risk factors associated with PSD in elderly individuals (≥65 years) using a large, nationally representative dataset.

Methods

Data from the Healthcare Cost and Utilization Project National Inpatient Sample (2010-2019) were analyzed. Elderly patients with a primary diagnosis of stroke were selected, and PSD was defined using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM)
