Royal Free London publishes audit into Streams app

12 June 2018

The Royal Free London NHS Foundation Trust (RFL) has today published an audit into its use of Streams, an app which is helping to deliver improved care to patients with acute kidney injury (AKI).

The audit was completed to comply with undertakings following an investigation into the use of the app by the Information Commissioner in July 2017.

The audit was carried out by Linklaters LLP. Their conclusion is that RFL’s use of Streams is lawful and complies with data protection laws. While the audit identified areas in which further improvement could be made, it contains the following important conclusions:

  • DeepMind only uses patient information for the purpose of providing Streams. It does so under the direction of RFL and in strictly controlled conditions. DeepMind is not permitted to use patient information for any other purpose
  • Streams does not use artificial intelligence. Instead, it implements a simple decision tree used across the whole of the NHS.
  • The audit revealed nothing that casts doubt on the safety and security of the patient information used in Streams. The audit confirmed appropriate systems and controls are in place to protect patient information.

Streams is a secure instant alert app which delivers improved care for patients by getting the right data to the right clinician at the right time. Similar to a breaking news alert on a mobile phone, the technology notifies nurses and doctors immediately when test results show a patient is at risk of becoming seriously ill, and provides all the clinical information they need to take action.

Each year, many thousands of people in UK hospitals die preventably from conditions like AKI, because the warning signs are not picked up and acted on in time. AKI is estimated to cause 40,000 deaths and cost the NHS over £1 billion every year.

Streams integrates different types of data and test results from a range of existing IT systems used by the Royal Free Hospital. Because patient information is displayed in one place – on a mobile application – it reduces the administrative burden on staff and means they can dedicate more time to delivering direct patient care.

The Streams app was built in close collaboration between experts at DeepMind and clinicians at the Royal Free London. It was introduced in January 2017 and is already helping to provide better, safer and faster care to our patients. Nurses report it is saving them around two hours each day – time which would previously have been spent looking through paper patient notes.

Dr Chris Streather, RFL group chief medical officer, said:  

“The Information Commissioner’s investigation last year identified a number of areas of improvement. We accepted those findings and took a number of remedial steps to address them. We welcome the outcome of the audit which confirms our use of Streams complies with data protection laws and would like to thank the Information Commissioner’s Office for their assistance throughout this process.

“We passionately believe in the power of technology to improve care for patients and that has always been the motivation for our Streams app.

“This project is one of the first of its kind in the UK and we have learnt important lessons which will be applicable to the whole of the NHS. We are pleased that the audit concludes we are getting it right and hope that will reassure our patients.

“We are proud of our partnership with DeepMind and look forward to continuing to work closely with them in the future to ensure that the NHS has the opportunity to benefit from the technology we all use in our everyday lives.”
