In a live discussion on C-SPAN, Dr. Gellad discussed the potential impact of the proposed CVS-Aetna merger.  The merger could transform the way that health care is delivered by making it more accessible to consumers and managing costs.  In taking questions from callers, Dr. Gellad also described how the merger relates to current trends in health care and business, such as availability of care providers in rural areas, competition among pharmacies, and the rise of mail-order pharmaceutical delivery.  The CVS-Aetna, says Dr. Gellad, could more closely integrate pharmacists with the rest of the health care team and potentially remove some barriers to care.
