The Health Care Debates that occurred in Washington over the past year were largely irrelevant to what’s happening in the health care marketplace. Republicans couldn’t repeal the Affordable Care Act but they made some changes that weakened it. Those changes will increase insurance premiums in the individual market but they do nothing to address the most significant trends that are evolving across the system. To understand the important trends, one must look elsewhere. In March, three researchers from the Harvard T. H. Chan School of Public Health published a study in JAMA analyzing the well-known reality that the United States spends dramatically more on health care than other wealthy countries. They compared the US, where health care consumes 17.8 per cent of gross domestic product, to 10 comparable nations where the mean expenditure is 11.5 percent.
