Consolidation of industries and lack of competition has been an ongoing issue for health care delivery—and a new report illustrates how some companies dominate sectors of health care that have a direct impact on costs to consumers and insurance plans.

The report, “America’s Concentration Crisis,” was released by the Open Markets Institute, based on research by IBISWorld. Although most of the concern about consolidation in health care usually focuses on insurance companies or provider systems, this report outlines how industries such as medical supplies or pharmaceutical manufacturers can also be concentrated among a few names. This concentration can lead to near-monopoly conditions and drive up costs, the institute said.
