Influencing global policy on antiretroviral treatment priorities

UCL research showed that expansion of anti-retroviral treatment (ART) in developing countries should proceed, despite the unavailability of viral load testing. There had been concern that such an approach would lead to poorer outcomes and drug resistance but modelling showed that this concern should not hold up the roll-out. There are now nearly ten million people receiving treatment.

A clinical management service for stroke prevention

UCL research has developed international standards for electronic health records (EHRs), enabling patient records to move with them to different health providers and clinicians in different settings to collaborate more effectively. The work has been successfully commercialised as a stroke prevention service through spinout company Helicon Health.

The Marmot Review: national and local policies to redress social inequalities in health

In 2008, Professor Sir Michael Marmot (UCL Epidemiology & Public Health) was asked by the Secretary of State for Health to chair an independent review to propose the most effective evidence-based strategies for reducing health inequalities in England. The Marmot Review, published in 2010, has fundamentally shifted discourse on health inequalities in the UK and internationally.
