I recently heard BJ Fogg speak at a design conference. He has facsinating material on persuasion.
He also has developed a great model of behavior change which I feel could help redesign heathcare worker’s behavior in terms of safety practices.
Here is a link to his model http://www.behaviormodel.org/
Here is a link to his behavior grid http://www.behaviorgrid.org/
Here is a link to his interactive behvavior change wizard http://www.behaviorwizard.org/wp/
Book on Mobile persuasion http://mobilepersuasion.com/
