Risk stratification is a research area that involves the identification and classification of individuals or populations based on their likelihood of experiencing a certain health outcome or event. This process involves assessing and analyzing various risk factors, such as demographic characteristics, medical history, genetic predisposition, lifestyle habits, and environmental factors, to determine an individual's level of risk for a particular condition or disease. The goal of risk stratification research is to improve prevention and intervention strategies by targeting high-risk individuals for more intensive monitoring, screening, or treatment, while reducing unnecessary interventions for individuals at lower risk. This approach can help healthcare providers allocate resources more effectively, personalize treatment plans, and ultimately improve patient outcomes. Risk stratification is used in a variety of fields, including cardiology, oncology, epidemiology, and public health.
