요약	The CHA₂DS₂-VASc score, developed by Lip, Nieuwlaat, and colleagues in 2010, is a 9-point risk stratification tool for predicting annual stroke and systemic thromboembolism risk in patients with atrial fibrillation. It is the recommended score by major cardiology guidelines for guiding anticoagulation decisions.	The Quick Sequential Organ Failure Assessment (qSOFA) score, introduced by the Sepsis-3 taskforce in 2016, is a rapid 3-variable bedside screening tool for identifying non-ICU patients at high risk of sepsis-related mortality. It uses altered mentation, systolic hypotension, and tachypnea to quickly stratify patients without requiring laboratory testing.	The Wells score, developed by Wells et al. in 1994, is a clinical prediction rule that stratifies patients into low, intermediate, or high pretest probability of deep vein thrombosis (DVT). It combines seven clinical features to guide diagnostic testing decisions and reduce unnecessary imaging in suspected DVT patients.
