The report says: ¡°Choosing the top statements from each medical school was made exceptionally difficult by the wide variety of high-quality case studies received. This quality ¨C consistently high across all medical schools ¨C is evidence of a thriving UK academic life sciences sector.

¡°Collaboration between medical schools and movement of researchers from institution to institution are crucial elements of many of the case studies we have featured,¡± it adds.

Other examples include research from the University of Liverpool that led to large-scale vaccination programmes against Japanese encephalitis in Asia, which prevented an estimated 214,000 deaths.

Chris Day, deputy chair of the Medical Schools Council and chair of the REF¡¯s clinical medicine sub-panel, said: ¡°The research excellence framework¡¯s focus on impact has shown how the benefits of medical research can be quantified in powerful terms, such as in lives improved and saved, costs cut to the Health Service and money put into the economy. But those numbers don¡¯t mean anything without understanding the work that brought them about.

¡°Some of the case studies in Health of the Nation will be known to the public but many will not, and these are equally innovative and making huge benefits to the population right now, both in the UK and globally,¡± he added.
