Dx error and librarians -- the sequel!

Nice that we are cued up to do this session again (in a 6 hour format instead of 4) in 2012 at MLA in Seattle:

Lorri Zipperer, Elaine Alligood, Linda Williams, and Barbara Bowers Jones. Diagnostic Error & Patient Safety—Team Up & Tackle It. Minneapolis, MN: Medical Library Association Annual conference: May 13, 2011

Do you have stories, better practices, ideas etc about how an understanding of cognitive bias and failure can inform the design of services and activities of librarians and information professionals in hospitals? If so, do tell! Any front line experiences we can fold into the expanded talk will be appreciated.
