Ballard AY, et al. – Authors conduct this study to explore the patterns of use and barriers and facilitators to use of two decision aids, the Statin Choice Decision Aid (SCDA) and the Diabetes Medication Choice Decision Aid (DMCDA), in primary care practices where the decision aids are embedded in the electronic medical records (EMRs). Although guidelines for both the treatment of blood cholesterol with a statin and for the treatment of hyperglycemia in type 2 diabetes recommend shared decision making, there appeared lack of routine use of tools that facilitate shared decision making even when embedded in the EMR. Even when decision aids are used, their use may not reflect patient centered care.
