Combining Real-World and Clinical Trial Data Through Privacy-Preserving Record Linkage: Opportunities and Challenges—A Narrative Review

Written by Aetion | Sep 26, 2025

Randomized clinical trials (RCTs) and real-world data (RWD) each offer valuable observations of the patient journey, yet these insights are often disconnected. Privacy-preserving record linkage (PPRL) can bridge these data sources to strengthen evidence generation by streamlining research and enhancing the quality of available data.

Study Overview

This narrative review, published in Health Science Reports, explores how PPRL connects RCTs and RWD to create richer patient histories and support innovative trial designs. By linking these data sources, researchers can improve decision-making across the pre- and post-marketing phases of drug development. The authors also emphasize the need for additional research and real-world examples to fully demonstrate PPRL’s potential in advancing evidence generation and regulatory decisions.
