The NIH Pragmatic Trials Collaboratory aims to improve the way clinical trials are conducted by creating a new infrastructure for collaborative research with healthcare systems, ultimately ensuring that healthcare providers and patients can make decisions based on the best available clinical evidence. The Collaboratory supports the design and rapid execution of pragmatic clinical trial Demonstration Projects to address questions of major public health importance and engage healthcare delivery systems in research partnerships. The Collaboratory also provides training resources on how to design, conduct, and disseminate embedded pragmatic clinical trials (ePCTs).
