PeerAtlas is a database of medical algorithms that are created, edited, and peer-reviewed by the site's a Wikipedia for medical algorithms. The only real difference from a traditional wiki (aside from the user interface) is that after submitting a new algorithm it goes through a peer-review process before being approved for everyone to see. The reviewers are registered users of the site (mostly physicians) who are selected at random and reassigned new algorithms to vote on once per week. Updates to algorithms are approved by the site's moderators.

I've recently added about ten algorithms regarding incidental findings in radiology since that's my specialty, but algorithms from any medical specialty are accepted. Every box in an algorithm can be referenced and I plan on adding references to my algorithms soon.
