Recent statistics indicate that the number of individuals without health insurance has risen to 47 million in the United States. Those with health coverage are facing rapidly rising premiums, as new medical technologies have driven health expenditures in the U.S. to exceed 2 trillion dollars per year. Dr. Mark McClellan, the newly named director of the Engelberg Center for Healthcare Reform at the Brookings Institution joins us to discuss these issues, as well as other challenges facing the U.S. healthcare system. McClellan has a distinguished record in public service and in academia. He is the former administrator for the Centers for Medicare and Medicaid Services (2004-2006) and the former commissioner of the Food and Drug Administration (2002-2004).
