The health care industry continues to face demands for cost control, while needing to show improvements in quality of care. Policy makers are taking the lead. The U.S. Accountable Care Act (Obamacare), signed into law in March 2010, identifies these as its core goals. While there seems to be a near equal split between ACA enthusiasts and critics, the “trend towards accountability in healthcare is irreversible,” says to Sangita Singh, a senior vice president and global business head at Wipro Technologies. Health care and life sciences companies must reinvent business strategies to survive and grow, says Patricia Danzon, Wharton professor of health care management.
