Sammanfattning	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.	CURB-65, derived and validated by Lim et al. in 2003, is a 5-point severity of illness score for community-acquired pneumonia (CAP). It assesses confusion, urea nitrogen, respiratory rate, blood pressure, and age ≥65 years to stratify mortality risk and guide admission and treatment 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.
