Equity refers to the fairness of delivery, allocation of resources, and achievement of outcomes. Measures of health inequities quantify systematic disparities in health and healthcare between population groups with different levels of social disadvantage.
What We Do
The Three Es Framework: Efficiency, Effectiveness and Equity
One important aspect in the discourse of attainment of equity in health and healthcare is the trade-off between the three Es: Efficiency, Effectiveness and Equity. Generally, efficiency measures how well the system is utilizing its resources and effectiveness is a measure of how well the system meets a need or achieves an objective. In our research projects, we use optimization models to account for the trade-off between the three Es in designing interventions to improve healthcare access and health outcomes.
Research in uncovering geographic disparities has emerged as economic and social equity advocates recognized that where people live influences their opportunities for economic development, access to quality healthcare, and political participation. Within this research focus area, we study statistical and mathematical models that account for both time and regional variations along with identifying underlying contributors to inequities in health and healthcare. The goal is to build the foundation of measuring and monitoring equity in health, to ultimately improve decision making and fairness.
