Description: Health equity assessment refers to the systematic analysis of access, treatment, and outcomes of healthcare, aimed at identifying and addressing disparities affecting different population groups. This concept involves not only measuring the quality and effectiveness of health services but also considering social, economic, and cultural factors that can influence people’s health. Health equity seeks to ensure that all individuals, regardless of their ethnic background, gender, socioeconomic status, or geographic location, have access to quality healthcare and optimal health outcomes. This approach is fundamental to promoting social justice and improving public health overall, as health inequalities can perpetuate cycles of poverty and marginalization. Health equity assessment is based on ethical principles that demand health systems be fair and equitable, and that measures be taken to eliminate barriers preventing access to healthcare. In this sense, it becomes an essential tool for policymakers, researchers, and health professionals, as it provides valuable information for decision-making and the implementation of interventions that promote health equity.
