Steps to Improve Data Gathering of Rare Diseases

The authors of four separate studies on the economic burden of rare diseases recently collaborated on piece in Health Affairs calling for concrete steps to address gaps in data that make it difficult to track rare diseases in the healthcare system. Though the authors came to similar conclusions in their reports, they were also stymied by existing data constraints, such as a lack of codes for rare diseases, differing data structures of electronic health records, and missed opportunities to gather data through public health surveys. We spoke to Joni Rutter, acting director of the National Center for Advancing Translational Sciences; and Annie Kennedy, chief of policy and advocacy for the Everylife Foundation for Rare Diseases, about the economic burden of rare diseases, the data constraints that limit a complete understanding of the impact they have, and what steps can be taken to improve the availability of patient data.
