Innovative designs for randomized controlled trials (RCTs) utilising existing health data are increasingly used in healthcare intervention research. This includes trial designs that use existing data sources (randomized registry trials, administrative health record trials, and electronic health record trials) as well as Trials within Cohorts (TwiCs) designs. How efficient are these trial designs? How should these designs be analysed?

This one-day international symposium, taking place on May 15, 2019 in London (UK) brings together experts in these designs in order to: share knowledge of the design, provide a forum to discuss and debate, and identify future directions for research. The MiRoR project coordinator, Prof. Isabelle Boutron, is contributing to this event.

A Call for abstracts is now open, closing on 28th February, 2019, welcoming submissions for oral and poster presentations concerning any aspect relating to the efficiency and/or analysis of trials utilising cohorts or routinely collected health data.
