About - RWD versus RWE
Real World Data and Real World Evidence – What’s the difference?
Real World Data (RWD) is health data, usually created by healthcare professionals and also by patients, as part of routine health care and not as part of a research study. It is usually held in hospital and GP electronic health record systems, and by patients in personal health records and various apps. When Real World Data are analysed as part of research, the new evidence (knowledge) generated from this is called Real World Evidence (RWE).
