AHRQ has a health literacy curriculum for pharmacists: Strategies to Improve Communication between Pharmacy Staff and Patients: Training Program for Pharmacy Staff.
It includes a slide set and a trainer’s guide. It focuses on communication on medication, but could be used with clinicians other than pharmacists. You can find it at: http://www.ahrq.gov/qual/pharmlit/pharmtrain.htm
