First, What Are Real-World Data (RWD) and Real-World Evidence (RWE)?

Before we dive into the exciting real world data jobs available, let’s clarify what we mean by Real-World Data (RWD) and Real-World Evidence (RWE). RWD is the raw material – information collected from routine healthcare settings – and RWE is the valuable insight derived from analyzing that data. The crucial link between them is the change of disparate data points into actionable knowledge that can inform medical decisions, drug development, and patient care.

Real-World Data (RWD) encompasses information relating to patient health status and/or the delivery of healthcare routinely collected from a variety of sources. Real-World Evidence (RWE) is the clinical evidence regarding the usage and potential benefits or risks of a medical product derived from analysis of RWD. Think of RWD as the ingredients, and RWE as the delicious, insightful meal prepared from them. For a deeper dive, check out our Real-World Data vs. Evidence: Ultimate Guide.

Real-World Data (Raw Inputs)	Real-World Evidence (Analyzed Outputs)
Raw, unstructured, or structured data	Clinical insights, treatment patterns, safety signals
Directly collected observations	Conclusions drawn from RWD analysis
Foundational information	Actionable knowledge for decision-making
