What is the National Institutes of Health (NIH)?
The National Institutes of Health (NIH) is the principal U.S. federal agency for biomedical and public health research. It is made up of many separate institutes and centers, each generally focused on particular diseases, organ systems, or areas of science.
The NIH funds research at universities and institutions across the country and around the world, and it also conducts its own studies through intramural programs. Its mission spans the prevention, diagnosis, and treatment of disease.
Why does the NIH matter in healthcare and research?
As one of the largest sources of biomedical research funding, the NIH shapes which scientific questions get pursued and underwrites much of the foundational work that later informs clinical practice. Its grants and programs influence the direction of medical research nationally.
The evidence generated through NIH-supported research ultimately feeds into the diagnostics, treatments, and guidelines that providers rely on. For the broader clinical and regulatory landscape, the agency is a cornerstone of how new medical knowledge is created and validated.
