The BURQOL-RD project aims to develop a model to quantify the socio-economic burden and health-related quality of life of rare disease patients and caregivers in Europe. The 3-year project will measure these impacts for 10 rare diseases across 8 countries. Associated partners will carry out core activities while collaborating partners provide specific contributions. The project will generate standardized tools, conduct a pilot study, and refine the tools for ongoing rare disease assessment and monitoring across Europe.
