A Senate inquiry seeks details from Ascension about its partnership with Google called Project Nightingale. The Wall Street Journal previously reported that Project Nightingale allows Google to gain access to the health records of Ascension’s patients in 21 states without their consent. Both Google and Ascension have stressed that their partnership complies with HIPAA’s rules permitting covered entities to share PHI with business associates. The Senate previously investigated Google’s involvement in Project Nightingale, but Senators Bill Cassidy, M.D. (R-LA), Elizabeth Warren (D-Mass), and Richard Blumenthal (D-Conn) described Google’s response as incomplete. The Senators now seek to obtain the information that Google failed to provide about Project Nightingale, including a list of the PHI that Google is receiving from Ascension and the number of health records that Ascension has provided Google. Ascension’s response is due by March 23.
