Delirium in the Geriatric Intermediate Care Unit in Ain-Shams University Hospitals.

Background: Delirium in geriatric patients is one of the most severe and fatal complications during hospital stays, be-ing related to poor prognosis. Aim of Study: Assess the prevalence of delirium in senior patients in the Geriatric Intermediate Care Unit (IMCU), and any potential risk factors. Subjects and Methods: From November 2024 to March 2025, 196 senior patients admitted to the IMCU participated in a cross-sectional study. Delirium was diagnosed using the Confusion Assessment Method (CAM) criteria, and its severi-ty was evaluated using the Confusion Assessment Method Se-verity (CAM-S) short form. Every participant received a thor-ough evaluation that included laboratory tests, Glasgow Coma Scale (GCS), Clinical Frailty Scale (CFS), Sequential Organ Failure Assessment (SOFA) score, Faces Pain Scale – Revised (FPS-R), Charlson Comorbidity Index (CCI), and history of cognitive impairment. Results: The most frequent reason for the geriatric IMCU admission was delirium the prevalence was 37.8%. Hypoac-tive, hyperactive, and mixed were 70.8%, 27.8%, and 1.4%, respectively. Infections are the most frequent cause of delir-ium. Functional, cognitive impairment, length of stay in the IMCU >5 days, GCS ≤13, CFS >7, and WBC >11.5 ×10^3/ uL were risk factors. Conclusion: Elderly patients had a high prevalence of de-lirium; improved results require early detection and control of independent risk factors.
