In our accredited CE, are we allowed to discuss new and evolving topics that are not yet based on current science?

Yes, as long as those topics are clearly identified as such.  The ACCME states that accredited CE is an appropriate place to “discuss, debate, and explore new and evolving topics,” but that providers need to find a way to engage with these topics without “advocating for, or promoting, practices that are not, or not yet adequately based on current science, evidence, and clinical reasoning”.  (Standard 1: Ensure Content is Valid)
