It's not just medical residents. Doctors do refresh their knowledge from videos online. And they totally google for information. But I don't think it's what many people imagine when reading it.
> How can doctors tell which videos are valid and which contain bogus information?
They're doctors. They had years of training and know the basics of what they're booking up. It's closer to experienced developers looking up specific usage for some tool which they're familiar with otherwise, rather than learning from scratch.
Sure, there's going to be some extreme bad cases, but those are bad doctors in general, the source of info is not relevant.
