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 Malnutrition Screening Tool (MST), developed by Michelle Ferguson and colleagues in 1999, is a brief, validated screening instrument designed to identify hospitalized patients at risk for malnutrition. The tool consists of two simple questions about recent unintentional weight loss and reduced food intake, yielding a quick numerical score. Since its publication, the MST has become widely adopted in acute hospitals, residential aged care facilities, and community settings as a rapid, reliable first-line screen for nutritional risk.
