Senate Finance Committee Chairman Ron Wyden and Ranking Member Chuck Grassley are asking providers, patients, insurers, entrepreneurs, and other stakeholders for ideas on ways to improve the availability and utility of health care data, while protecting patient privacy. In particular, the Senators are requesting information on: the data sources that should be made more broadly available; the form such data should be conveyed; ways to reduce the unnecessary fragmentation of health care data; and reforms to overcome barriers that stand in the way of effective use of existing data sources. Comments will be accepted until August 12, 2014.
