The NIHR's mission is to improve the health and wealth of the nation.

Funded by the Department of Health and Social Care, we invest over £1 billion a year in research that provides people working in the front lines of the NHS, public health and social care with the evidence they need to better support patients, service users and the public.

Read about how our work is influencing care, and making a positive difference to people, and the economy.

Improving outcomes after trauma and blood loss

NIHR researchers have developed new ways of diagnosing and treating severe bleeding after traumatic injury. Their revised protocol has been adopted by almost all major trauma centres in the UK and incorporated into clinical guidelines around the world, saving hundreds of lives and making significant cost savings for the NHS.

Optimal care homes

Relational working key in delivering high-quality healthcare in care homes

The NIHR-funded Optimal study showed how care home and NHS services can work together to improve residents’ care. Its results have informed national policy and shaped changes to service delivery to improve the quality of life, health care and health planning for people living in care homes.

Saving lives with new treatments for anorexia nervosa

A team at the NIHR Maudsley Biomedical Research Centre has developed a series of new approaches to improve treatment and support for patients with anorexia nervosa and their caregivers at all stages of the illness. Their evidence-based interventions and models of care have been integrated into NICE guidelines and widely adopted within the NHS.

School-based intervention to tackle childhood obesity informs UK policy

A study of 6 to 7 year-old children carried out by NIHR-funded researchers found that school-based interventions alone are unlikely to improve childhood obesity. The results have informed the NHS and other public agencies about the most appropriate methods to prevent and manage childhood obesity.

Using patients’ electronic health records to improve health and care

NIHR-funded researchers developed a data platform called CALIBER for more than 30 studies on the onset and progression of cardiovascular diseases. CALIBER has now expanded to provide access to linked data on more than 50 million patients and has supported over 100 research projects across a range of conditions, including COVID-19.

Changing behaviour to combat tooth decay

A low-cost talking intervention has been shown to prevent tooth decay in children. NHS dental nurses are now offered training in the technique, and commissioners in the North West have committed to introducing the intervention into dental services.

Preventing cancer by extending vaccination to boys

Evidence from NIHR-funded research contributed to a change in immunisation policy that made the human papillomavirus (HPV) vaccine available to boys as well as girls, potentially preventing more than 100,000 cancers over 50 years.

Helping people stay warm at home in later life

NIHR researchers used interviews with older people in South Yorkshire to develop a website and other resources to help health and social care providers and organisations support vulnerable older people to keep warm and well during cold weather. Their resources have informed national and local support aimed at improving older people’s living conditions.

Innovative model identifies high-risk people for priority COVID-19 vaccination

NIHR-funded researchers have developed a model called QCovid® that predicts the risk of people becoming seriously ill or dying from COVID-19. The model has been used to inform UK health policy, and its use by NHS Digital helped prioritise 820,000 people for vaccination.

Free bus travel keeps young Londoners socially connected

Free bus travel in London is a socially inclusive way for young people to access education, services and social activities without reducing their physical activity levels or displacing other age groups from bus travel.
