But the lack of compliance with prescriptions has enormous financial ramifications. Dr. Steve Miller, senior vice president & chief medical officer, research and clinical sciences for Express Scripts, one of the nation's largest managers of pharmacy benefits, tells host Bruce Japsen about Express Scripts most recent survey on patient behavior when it comes to pharmaceuticals. He also talks about how, based on this research, improved patient compliance and other factors could save the healthcare system $100 billion a year.
