Trends in hospital consolidation: the formation of local systems

Abstract

During the past decade the hospital industry has made profound organizational changes, including the extensive consolidation of hospitals through merger and the formation of hospital systems. Although the rate of hospital system acquisitions may be slowing, the local presence of hospital systems is growing. Locally concentrated systems have been formed by both for-profit and nonprofit hospitals. Researchers have tended to ignore acquisitions or have portrayed system formation as primarily an issue of hospital ownership conversion, thereby focusing on the expansion of national, for-profit systems. This has left a large gap in policymakers' understanding of how locally concentrated systems may affect patient care and competition.
