Few communities in the United States have been exempt from the recent wave of consolidation among health care providers, whether it is hospital-to-hospital mergers and acquisitions (horizontal consolidation) or hospital acquisitions of physician groups and other ambulatory service providers (vertical consolidation). Increased provider concentration has been demonstrated to lead to higher provider reimbursement rates and thus higher premiums for people with private insurance, although outcomes vary, market to market.
To examine the strategies that private insurance companies and employer-purchasers use to constrain health care cost growth and how they are affected by increased provider consolidation, we conducted six market level, qualitative case studies, focusing on mid-sized health care markets in which there had been recent consolidation activity.
