Google DeepMind’s cofounder has defended the data-sharing agreement that his company signed with the NHS after privacy campaigners questioned the extent of the partnership.
Mustafa Suleyman, cofounder of DeepMind and head of the company’s healthcare division, told The Guardian that Google DeepMind is better placed to handle sensitive data than any other company, pointing to Google’s experience of securing highly personal information in other fields.
“As Googlers, we have the very best privacy and secure infrastructure for managing the most sensitive data in the world,” said Suleyman. “That’s something we’re able to draw upon as we’re such a core part of Google.
“When we developed our information governance toolkit and we submitted that for assessment to the health and social care information centre (HSCIC), which approves these data-sharing agreements, we got 100% for our toolkit. There’s pretty much nobody else who’s been able to get a score as high as that.”
DeepMind was awarded the highest possible rating for its information governance processes (level 3) by the HSCIC, according to Suleyman. “The vast majority of other organisations in the country only have a level two, including most of the hospitals,” he said.
Suleyman’s comments were made after New Scientist revealed that Google DeepMind has access to medical data for 1.6 million patients across three London hospitals: Barnet, Chase Farm, and the Royal Free hospitals.
Through the data-sharing agreement with the NHS, Google DeepMind will be able to see data that is unrelated to kidney function, including whether people are HIV-positive as well as details of drug overdoses and abortions. The data is anonymised, meaning DeepMind staff shouldn’t be able to see whose data they are looking at.
DeepMind announced in February that it was working on two apps in partnership with the NHS: Streams and Hark. The Streams app, which the data-sharing agreement is centred around, aims to monitor and detect acute kidney injuries (AKI), which kill more than 1,000 people a month.
Suleyman highlighted that acute kidney injuries can be treated with antibiotics and intravenous fluid if caught early, saying that the timescale for intervention is a matter of hours.
The data that DeepMind processes is kept separate from the wider Google business but privacy campaigners are angry at the extent of the partnership and confused as to why it was not made public.
Sam Smith, who runs health data group MedConfidential, told New Scientist that this is the first it had heard about DeepMind getting access to full medical records. “This is not just about kidney function,” he said. “They’re getting the full data.”
Neil Lawrence, professor of machine learning and computational biology at the University of Sheffield told Business Insider: “I’m sure they’re [Google DeepMind] well meaning, but I don’t think we should be doing all this in such secrecy. I think it’s a little strange that this information isn’t public as a matter of course.”
DeepMind is known for its work in artificial intelligence but the algorithm being used in the Streams app — outlined on this NHS England website — is devoid of AI. However, Suleyman said DeepMind’s AI technology could be applied to Streams at a later date. Using AI in healthcare could significantly improve the way and speed at which people are diagnosed and treated, according to DeepMind.
The NHS has data-sharing agreements with approximately non-NHS 1,500 organisations, meaning DeepMind certainly isn’t the only one to pull in patient data, process it with an algorithm, and feed it back to front line NHS staff.
