Real-World Evidence

Real World Evidence

The explosion in patient-generated data and advancements in technology provide unprecedented opportunities for improving patient care.

Our Thinking

Patient-generated data holds great promise for the future of every phase of clinical research, helping to usher in a new era of pragmatic clinical trials. Data collected from “real-world” patients can improve trial design, aid trial participant recruitment, help to generalize research findings to broader populations, and provide a clearer picture of how therapeutic interventions work outside of the research setting. Yet, along with these opportunities, comes unique challenges. How do we shift real-world evidence beyond its most accepted use in post-approval surveillance models to use in pre-approval phase to streamline clinical trials?  How do we use patient-generated data to help guide policy decisions and improve the drug and device approval process?

Through its collaboration with PCORnet, the NIH Health Care Systems Research Collaboratory, The Robert J. Margolis Center for Health Policy, and others, the DCRI is working to gain and share knowledge about how real-world evidence can make pragmatic trials a powerful tool for evidence generation.

"How do we use data captured from the actual experiences of patients during routine patient care to strengthen the evidence base for the approval, safety, and effectiveness of drugs?"

Noted for using and building national data resources that inform our understanding of health care delivery, the comparative effectiveness and safety of medical products, and patient-centered outcomes across a broad array of clinical conditions and for developing large networks that enable execution of analyses to answer complex questions without transmittal of patient-level data.

Incorporating Real-World Evidence in Clinical Research

Brad Hammill, DrPH, discusses how the DCRI is leveraging new real-world data sources to conduct health services research. He explains that the way data was traditionally collected for clinical trials is changing, and how essential it is for researchers to learn how to utilize real-world data sources moving forward. This includes the best methods for incorporating real-world data and setting the standards necessary to do it responsibly.

DCRI Partners with Datavant to Change Clinical Research

News Item

The DCRI will be working with Datavant, a healthcare technology company, to accelerate data-driven approaches in drug development and facilitate rapid scaling of best practices in clinical research.

Collaboration: The Duke-Margolis
Center for Health Policy

The DCRI is partnering with the Duke-Margolis Center for Health Policy to coordinate resources across Duke and change how scientific discoveries inform policymaking. With the Center for Population Health Sciences, the DCRI and Duke-Margolis are actively pursuing acquisition of Center for Medicare and Medicaid Services claims data that will enable faculty to investigate longitudinal outcomes for questions on clinical outcomes, population health measures, and measures of value and accountable care. Together, the centers are developing outreach, documentation, and governance to maximize access and maintain the highest levels of research integrity and academic productivity.
