refers to the clinical evidence about the usage, benefits, and potential risks of a treatment, medical product, or intervention that is derived from analyzing real-world data (RWD). It uses appropriate statistical and analytical methods to evaluate effectiveness and safety, uncover care gaps, and identify opportunities to improve healthcare delivery in routine clinical practice, outside of the controlled conditions of traditional clinical trials.
Abbreviation: RWE
Example
After a new rheumatoid arthritis medication is approved, researchers collect insurance claims, electronic health records, and patient registries from thousands of people taking the drug in everyday settings. By analyzing this real-world data with advanced statistical techniques, they generate real-world evidence showing the drug’s long-term effectiveness, side-effect profile, and adherence patterns compared to standard treatments.
