Corporate Investors Increased Common Ownership In Hospitals And The Postacute Care And Hospice Sectors [Market Concentration]

The sharing of investors across firms is a new antitrust focus because of its potential negative effects on competition. Historically, the ability to track common investors across the continuum of health care providers has been limited. Thus, little is known about common investor ownership structures that might exist across health care delivery systems and how these linkages have evolved over time. We used data from the Provider Enrollment, Chain, and Ownership System of the Centers for Medicare and Medicaid Services to identify common investor ownership linkages across the acute care, postacute care, and hospice sectors within the same geographic markets. To our knowledge, this study provides the first description of common investor ownership trends in these sectors. We found that the percentage of acute care hospitals having common investor ties to the postacute or hospice sectors increased from 24.6 percent in 2005 to 48.9 percent in 2015. These changes have important implications for antitrust, payment, and regulatory policies.
