SUMMARY: According to a new report from the Institute for Clinical and Economic Review released on Tuesday, combined price hikes from seven drugs, in 2017 and 2018, contributed to a $5.1 billion increase in U.S. spending. None of those drugs had new important evidence to support the price increase, the study concluded. Why is this happening?

KEY SUMMARY: For years, businesses have responded to rising health care costs primarily by shifting more of those costs onto their employees, through higher deductibles and other cost-sharing. The average deductible is now 212% higher than it was in 2008. Employers cover more people than any other insurer and account for about 20% of all health care spending — almost $700 billion in 2017. With rising, costs companies may decide to form their own health insurance organizations.
