Google has collaborated with Ascension to share its healthcare and cloud computing data.  The deal gives access to datasets that could help it tune potentially lucrative artificial intelligence (AI) tools.

Google and Ascension, which operates 150 hospitals and more than 50 senior living facilities across the United States, said the healthcare provider would move some data and analytics tools in its facilities to Google’s servers.

The Wall Street Journal reported that Google would gain personal health-related information of millions of Americans across 21 states.

The Journal reported that the data involved in the project includes lab results, doctor diagnoses and hospitalization records, among other categories, and amounts to a complete health history, along with patient names and dates of birth.

Google has stated that patient data “cannot and will not be combined with any Google consumer data.” Ascension “are the stewards of the data, and we provide services on their behalf,” wrote Tariq Shaukat, president for industry products and solutions at Google Cloud.

In a press release, Ascension said the partnership is in compliance with the Health Insurance Portability and Accountability Act (HIPPA) which safeguards medical information. Google Cloud Chief Executive Officer Thomas Kurian has made it a priority in his first year on the job to aggressively chase business from leaders in six industries, including healthcare.

Ascension said it aims to use AI to help improve clinical effectiveness as well as patient safety. Google said  that the two  companies were in “early testing” on how to make better use of Ascension’s data.
