Real-World Evidence
Clinical evidence regarding the usage and potential benefits or risks of a device derived from real-world data.

Definition
RWE is the clinical evidence about the usage and potential benefits or risks of a medical product derived from analysis of Real-World Data (RWD), including EHRs, registries, and claims. What the regulation says
The FDA issues guidance on the use of Real-World Evidence (RWE) to support regulatory decision-making for medical devices, as outlined in their "Real-World Evidence Guidance for Medical Devices" document. This guidance details considerations for relevance and reliability of Real-World Data (RWD) sources, aligning with principles for valid scientific evidence. The EU Medical Device Regulation (EU MDR) also acknowledges the value of RWE, particularly for post-market surveillance (PMS) and substantiating clinical benefits and safety in the post-market phase, as described in Annex III, section 1.1(f) regarding clinical evaluation.What this means in practice
FDA accepts RWE to support regulatory decisions when relevance and reliability are demonstrated. RWE is increasingly important for AI/ML monitoring and PMS.Examples
- A medical device manufacturer uses RWE from a national patient registry to demonstrate the long-term safety and effectiveness of their implanted cardiac device in a diverse patient population.
- An AI-powered diagnostic software company utilizes RWE from de-identified electronic health records to support the clinical validity and utility of their algorithm for early disease detection.
- A pharmaceutical company submits RWE derived from insurance claims data to support a new indication for an approved drug, showing its effectiveness in a real-world setting outside of a controlled trial.
Common pitfalls
- •RWE derived from unreliable or biased RWD sources may not be accepted by regulatory authorities, leading to delays or rejection of submissions.
- •Failure to adequately document RWD collection methods and RWE analysis plans can undermine the credibility of the evidence.
- •Generalizing RWE from one population to another without proper justification is a common pitfall.
- •Ignoring potential confounding factors in RWD can lead to inaccurate conclusions about a medical product's performance.
- •Using RWE for indications not supported by the data's scope or context will be viewed critically by regulators, such as the FDA.
Frequently asked questions
RWE is derived from data collected in routine clinical practice or real-world settings, offering insights into product performance in a broader patient population and under typical usage conditions. Traditional clinical trials, conversely, are typically conducted in highly controlled environments with specific inclusion and exclusion criteria.
