The future of pragmatic trials

Edited by: Prof Marion Campbell and Prof Sandra Eldridge

A thematic series published in Trials.

This series includes articles reporting on current understandings of the role and definition of the pragmatic design (including comparative effectiveness research and real world trials), its use and applicability to modern-day healthcare challenges, its relevance to and use with novel trial designs (e.g. cohort multiple, stepped wedge, cluster randomized, registry trials), and considerations of ethical issues (e.g. streamlined research ethics review, patient engagement, different types of consent).

The deadline for submissions to this thematic series was 31 December 2020. Further articles will be added in due course following peer review.
