Lawton Burns is a professor of health care systems and management director of the Wharton Center for Health Management and Economics and author of a new book entitled The Business of Healthcare Innovation. While much has been written about doctors and hospitals government regulations and medical insurance issues Burns’ book looks at an area of healthcare that has not gotten much attention -- the producers of healthcare products ranging from pharmaceuticals and biotechnology to medical devices and information technology. Yet Burns would argue that a focus on the producer side of the healthcare equation is critical -- not just because we are increasingly more reliant on medical technology but also because of the ever escalating costs of advances in these areas. Burns talked to Knowledge at Wharton’s Mukul Pandya and Robbie Shell about the issues raised in his new book.
