Data in pragmatic trials often come from diverse sources such as electronic health records, administrative data, disease registries, and epidemiologic data from surveillance systems. While access and use of such data comes with challenges, such data can be population-based and reflect important variations in patient characteristics and care delivery systems. The primary focus of this section is related to the secondary use of these routinely collected data that are often derived from “real-world” routine care.

Modules from this section, featured in previous weeks, will be posted here over time.
