Led by the Clinical Effectiveness Group at Queen Mary University of London, in collaboration with the NHS and local authorities, this project employs an innovative algorithm named ASSIGN. Alongside Unique Property Reference Numbers (UPRNs), ASSIGN facilitates the analysis of health data at a household level, providing profound insights into broader health determinants. By linking de-identified patient addresses with geospatial data, the project aims to mitigate health inequalities, support evidence-based policymaking, and optimize resource allocation. With a steadfast commitment to privacy preservation and data-driven decision-making, this initiative epitomizes the transformative potential of geospatial technologies in advancing population health and societal well-being.
