Tóm tắt	The Confusion Assessment Method (CAM) is a widely validated diagnostic tool developed by Sharon K. Inouye and colleagues to detect delirium in hospitalized patients. Delirium is an acute change in mental status characterized by inattention, disorganized thinking, and altered consciousness that is often missed in clinical practice. The CAM provides a standardized, reproducible method for identifying delirium, which is associated with increased morbidity, mortality, and hospital costs.	The Early Warning Score (EWS), most commonly known as the National Early Warning Score (NEWS) in the UK, is a standardized tool for identifying acutely unwell patients at risk of deterioration. Developed by the Royal College of Physicians and validated through research by Smith, Prytherch, and colleagues, NEWS combines vital sign measurements and supplemental oxygen use to generate a composite score. High NEWS scores trigger escalated care responses, enabling early intervention before critical illness develops.
