概要	The Delirium Observation Screening Scale (DOS), developed by Mieke J. Schuurmans and colleagues in 2003, is a brief clinician-rated screening instrument designed to detect delirium in hospitalized older adults. Delirium—acute onset confusion, inattention, and disorganized thinking—is a common complication in hospitals and intensive care units that increases mortality, morbidity, and length of stay. The DOS captures the hallmark features of delirium through direct observation, making it practical for rapid, repeated screening in busy clinical settings.	The Clinical Frailty Scale (CFS), developed by Kenneth Rockwood and colleagues in 2005, is a brief, validated tool for assessing frailty in older adults. Frailty—a syndrome of diminished physiologic reserve, increased vulnerability, and reduced functional ability—is recognized as a distinct clinical state that predicts mortality, disability, and healthcare utilization independent of age and comorbidities. The CFS uses a seven-point (or nine-point in later versions) clinical judgment-based scale, making it practical and rapid for bedside use in hospitals, clinics, and long-term care.
