International Clinical Trials Day is celebrated around the world on May 20.
Held each year, it aims to commemorate the day that James Lind started his famous trial on the deadly disease scurvy.
The days is a focal point to raise awareness of the importance of research to health care, and highlights how partnerships between patients and healthcare practitioners are vital to high-quality, relevant research.
Professor Dame Sally Davies, chief medical officer and chief scientific adviser at the Department of Health, said: “Clinical Trials are a vital element of the work supported and funded by the National Institute for Health Research. Our role is to develop the research evidence to support decision making by professionals, policy makers and patients, make this evidence available, and make it available through publication to encourage its uptake and use.”
