Establishing Quality Indicators of Real-World Data and Leveraging Use in Clinical Research, 2019.04 - 2022.03

Summary： In order to utilize real-world data (RWD) in clinical research, it is critical to ensure that the data meet the quality standards suitable for the purpose of research. In the present study, we compared the quality of data obtained from clinical trials, which are relatively small but can be quality-controlled, to data obtained from medical records (RWD), which are large but cannot be quality-controlled. By evaluating the quality of RWD, we sought to determine the important considerations and limitations of using RWD in clinical research.
