What is RWD (Real World Data)

RWD is observational data obtained outside regulated clinical trials and generated during routine clinical practice. The US Food and Drug Administration (FDA) states that this data may come from a number of sources including electronic health records (EHRs), medical claims and billing activities, product and disease registries, patient-generated data (including in home-use settings) and data gathered from sources that can inform on health status, such as mobile devices.
