DaRe2THINK, led by Professor Dipak Kotecha, aims to improve health by screening over 13 million NHS patients' records to prevent strokes, blood clots, and vascular dementia in atrial fibrillation patients. The project requires inviting only 5.3 patients for one to be randomized, surpassing other trials. Supported by a Patient & Public Engagement team, it transforms NHS trial conduct, enhancing participation and contributing to the UK's life science strategy.
