What can the NHS learn from learning health systems?

What can the NHS learn from learning health systems? Drawing on a seminar held at the Nuffield Trust and on evidence and experience from the UK and internationally, this briefing identifies opportunities for local organisations and systems to make better use of health data, and recommends ways that national policy could promote the collaboration and greater use of analytics which underpin the 'learning health system' concept. We focus on lessons for the NHS – but many of the same actions could be taken across the wider health and care system.
